Abstract

This invention provides a driving link of chain and its application in a transmission. The driving link of chain comprises at least a cable-shaped actuating member penetrating into an annular engaging member, whose ends are connected to each other to form a link of chain. The cable-shaped actuating member can be one kind or several kinds of tightwire, iron chain, steel ball and resistance glue-rope. The annular engaging member can be either a spring or a string of steel loop. The said driving link of chain can be used to replace ordinary driving link of chain to construct a single-stage transmission or multi-stage transmission. And the said driving link of chain can be used to engage with a V-shaped groove having the activity and variability forming between an umbrella rotary table group of the driving wheel and an umbrella rotary table group of the driven wheel. Thus, a variable drive may be constructed of the driving link of chain, a governor and the V-shaped groove having the activity and variability between an umbrella rotary table group of the driven wheel. Comparing with the conventional tightwire loop, belt loop or toothed belt loop, the engagement of the driving chain having the engaging member and the actuating member and the umbrella toothed rotary table groups, the radial (or umbrella) web rotary table groups or the ratchet rotary table groups is easier. Furthermore, the driving chain is of simply structure and powerful transmission and it can't take place belt creep or disengagement no matter whether the rotate speed is quick or slow.

Description

 Transmission chain ring and application in transformer

Technical field

 The present invention relates to a transmission chain link of a mechanical transmission and its application in a single-stage, multi-stage or continuously variable transmission. technical background

 The most common transmission chains of mechanical transmissions include knotted links (such as bicycle links), iron links, smooth belt rings, toothed belt rings, endurance rubber ropes, etc., which are widely used, with advantages and disadvantages. In the transmission of wheels and driven wheels, the chain ring is both a transmission member and an engaging member, which is used to construct the transmission. The chain ring must meet the engagement with the transmission wheel and also bear the pulling force of the transmission. Take into account.

Taking the conventional continuously variable transmission as an example, the simplest continuously variable transmission is composed of an umbrella-shaped smooth turntable, a belt ring, and a governor. The governor continuously adjusts the width of its V-shaped groove to achieve stepless Speed adjustment, simple structure, 'easy maintenance, because both the belt ring and the umbrella turntable are smooth and easy to slip. If the belt ring is tightened, the belt is easy to grow and wear, and even break. If a steel grommet is used, it is not easy to break. The belt loop, although wear-resistant, is more slippery and not conducive to transmission. Some people have changed the umbrella-shaped smooth turntable into an umbrella-shaped toothed disc, and the smooth belt ring has been changed into a toothed belt ring. In the meantime, a special gear set is used to switch to stepless speed change; there are also ratchet-shaped turntables with movable ratchets. Step in or out in order to change the torque of the turntable to achieve stepless speed change. Both can be used, but the structure is complex and the efficacy is not good. The reason is that, regardless of the inclination of the umbrella-shaped tooth disc, whether it is the narrow inner and outer width of the tooth or the narrow outer width of the tooth groove, it is impossible for the tooth and the tooth groove to have the same inner and outer width, and the larger the diameter of the turntable Or, the smaller the inclination, the greater the difference between the inner and outer widths of the alveolar groove. This is the crux of the above-mentioned improvement scheme which is difficult to overcome. The spring is flexible and can be flexed and flexed arbitrarily. When the two ends are connected into a ring, the ring is similar to a ring chain. correspond. If the ring-shaped spring sleeve is clamped on the umbrella gear, whether it is sleeved on the inner, middle or outer periphery of the umbrella gear At one point, the gap between the tooth groove and the steel ring or the teeth and the steel ring can be engaged with each other. Even if only the half plate is fitted, the other half is not fitted. It can still be engaged, which fully shows the adaptability of the spring. Unfortunately, the spring cannot be used directly. It is used as a chain link for transmission, because the spring will be stretched during transmission, and cannot transmit power. Assuming that the spring can be prevented from extending, shouldn't it be used instead of a belt loop for transmission? The present invention is inspired by this to design a transmission chain link. The transmission chain link is decomposed into a meshing member and a force transmitting member, and it is used for general transmission and continuously variable transmission. The meshing member is matched with the umbrella gear and is specially used for adjustment. Speed ratio, power transmission parts are dedicated to transmitting power. Object of the invention

 One of the objectives of the present invention is to use a spring chain or a steel chain as a transmission chain. The transmission chain is decomposed into meshing elements and force transmission elements. The meshing elements mesh with the master and slave wheels. The force transmission elements are dedicated to transmitting power. , Improve the performance of the drive chain.

 Another object of the present invention is to replace the above-mentioned transmission chain rings with ordinary transmission chains, such as iron chain rings, smooth belt rings, toothed belt rings, endurance rubber ropes, etc., and apply them to known single-stage or multi-stage governors. To improve the transmission performance of this type of governor by taking into consideration both the meshing and force transmission aspects.

 A third object of the present invention is to design a continuously variable transmission by using the above-mentioned transmission chain ring, an umbrella-shaped turntable, and a governor to overcome the defects of easy slipping or complicated structure of the existing continuously variable transmission. Summary of invention

 The technical solution of the present invention is: a transmission chain link, which is characterized in that it is a chain link formed by at least one cable-like force transmitting member, which is threaded in the ring-shaped engaging member, and the two ends are respectively engaged. The member is any one or more of a steel cable, an iron chain, a steel ball string chain, or an endurance rubber rope, and the ring-type engaging member is any one of a spring or a string of steel rings.

 The transmission chain ring designed by the present invention is divided into a special spring-shaped steel wire chain ring and a string of steel ring-shaped ring chain links according to the difference of the engaging elements, and has the same effect and has wide adaptability.

Another technical solution of the present invention is as follows: The above-mentioned transmission chain ring is sleeved in the fixed U-shaped or V-shaped grooves of the single-stage or multi-stage governor set and the secondary turntable set. The surface of the U-shaped or V-shaped groove is the arrangement of teeth and grooves, or the arrangement of ratchets and grooves, or the teeth and grooves and ratchets and The mixed arrangement of spinous grooves may also be an arrangement of radial (or umbrella) nets and radial (or umbrella) grooves.

 In this solution, the above-mentioned transmission chain is used instead of the ordinary transmission chain ring in fixed V-grooves and U-grooves (the structure of the known driving wheels and driven wheels) to form a transmission with a fixed gear ratio. Engages with teeth, cogging or ratchet teeth, ratcheting or radial (umbrella) nets, radial (umbrella) grooves in the grooves of the driving wheel and the driven wheel, and the power transmission member specializes in power transmission, both Each division of labor makes the transmission more reliable.

 Another technical solution of the present invention is: a continuously variable transmission including the above transmission chain ring, comprising a governor and a main wheel umbrella type turntable group and a slave wheel umbrella type turntable group constituting a variable V-shaped groove, It is characterized in that the transmission chain ring is used to clamp the movable V-shaped grooves of the main umbrella-shaped turntable group and the slave-shaped umbrella-shaped turntable group, and the turntable surfaces on both sides of the variable V-shaped groove It is the arrangement of teeth and alveolar teeth, or the arrangement of ratchets and alveolar grooves, or a mixture of teeth and alveolars and ratchets and rachis, or a radial (or umbrella) mesh and radiation. Arrangement of like (or umbrella) grooves.

 In this solution, a spring or a series of steel rings are used as engaging elements, which are embedded in the movable variable V-shaped groove of the umbrella-shaped turntable group, and the movable variable V can be changed under the action of the governor. The width of the groove, which realizes the displacement of the meshing point, is specifically used for stepless adjustment of the speed ratio, which has nothing to do with the transmission of force; and the endurance rubber rope, steel cable, iron chain or steel ball string worn therein is used as a force transmission member The driving wheel is connected with the driven wheel to transmit power, and has nothing to do with the meshing of the transmission chain ring and the umbrella-type turntable group. This type of transmission chain link composed of a meshing element and a force transmission element is easier to connect with a umbrella-shaped tooth turntable group or a ratchet-shaped turntable group or a radial shape (umbrella type) than the traditional steel grommet, belt ring and toothed belt ring. The mesh turntables mesh with each other, no matter it runs fast or slow, they will not slip or come loose. The structure is simple and the transmission is more powerful.

If necessary, refer to the relevant sections in the above figures. Summary of the Invention

Referring to Figure 1-7, the conventional cable-like force-transmitting steel cable 117 is made of endurance rubber rope, iron chain 204 (see Figure 3-2, Figure 3-3) or steel ball string. Engagement piece whole spring steel In the wire ring 118, the two ends of each wire are welded into a ring at the welding points 119 and 120 to form a special spring-shaped steel wire chain link, which becomes a transmission chain link. The loop formed by the steel cable 117, the iron chain 204, the steel ball string, and the endurance rubber rope can prevent the spring from elongating. At least one cable-like force transmitting member (see 202 shown in Fig. 2-1 and Fig. 3-1) or two or more (see Fig. 2-2 and 203 shown in Fig. 3-2) to increase the pulling force The strength is limited by the capacity of the spring steel wire ring 118. Any one or more of steel rope, iron chain, steel ball chain, or endurance rubber rope can be used. The ring-shaped engaging member can be any spring or a series of steel rings, which have the same function and are used to mesh with the driving wheel.

 The above transmission chain rings can be used instead of ordinary transmission chain rings to construct single-stage or multi-speed transmissions. At least one (sometimes two or more transmission chain rings can be used at the same time to increase tension) In the fixed U-shaped or V-shaped grooves of the transmission's main turntable and slave turntable groups, the surface of the fixed U-shaped or V-shaped grooves should be set as the arrangement of teeth and grooves, or ratchet and The arrangement of ratchet grooves, or a mixed arrangement of teeth and tooth grooves and ratchet teeth and ratchet grooves, can also be an arrangement of radial (umbrella) nets and radial (umbrella) grooves. For the arrangement of these, refer to Figure 1 -1, Figure 1-2, Figure 1-3, Figure 1-4, and Figure 1-5 show the structure of the movable U-shaped or V-shaped groove surface, thereby forming a single-stage or multi-stage with more reliable work. Gearbox.

The above transmission chain ring can be used to replace the ordinary transmission chain ring for the construction of a continuously variable transmission. The conventional movable smooth umbrella-shaped turntable is changed to a movable umbrella-shaped turntable 110, as shown in Figure 1-1 and Figure 1-2. Or, it can be changed to a movable ratchet-shaped turntable 110, as shown in Figure 1-5, or it can be changed to a radial (umbrella) network turntable, as shown in Figure 1-11. This network turntable is similar to the conventional "electric fan net" The "cover" is composed of a net disk inner frame 10, a net disk outer frame 11, a net disk auxiliary frame 12, a radial (umbrella) net 13, a radial (umbrella) slot 15, and the like, among which the radial (umbrella) net 13 Welding point 14 is at the interface with the outer frame 11 of the disk. The width of the teeth 112 or the ratchet 115 should be aligned, and the inner and outer widths should be the same. The groove 113 should be narrower and wider than the outer diameter. When the turntable V-groove 201 (located on the master wheel) and 301 (located on the slave wheel) are inside, the teeth can be squeezed into the spring gap, or the steel ring of the spring can be squeezed into the groove and mesh with each other, as shown in Figure 1- As shown in Figure 6; or radial (umbrella) nets can be squeezed into the spring gap, or spring steel rings can be squeezed into radial (umbrella) grooves Engaged with each other, shown in Figure 1-12; small inclination, the peripheral tooth The slot is too wide, you can add shorter teeth 112, increase the number of teeth, as shown in Figure 1-1 and Figure 1-2, you can also add ratchet teeth at this position; umbrella teeth can be integrated with the turntable, as shown in Figure As shown in 1-2, one side of the wire 114 of the same type as the spring can also be pressed into a flat surface 116 to increase the welding surface and weld directly to the turntable, as shown in Figures 1-3 and 1-4, to enhance the firmness. To become arc-shaped turntable teeth; change the smooth turntable into a bevel-shaped or ratchet-shaped turntable with a rough surface, the purpose is to intermesh with the spring steel ring of a special spring-shaped ring-shaped steel cable chain link, like tooth-like engagement, Does not slip or come loose. Then two umbrella-shaped or ratchet-shaped turntables are combined into one set, at least two sets are combined into one set, one is a master turntable, and the other is a slave turntable, as shown in Figures 2 and 3, as if conventional In each group, one turntable 110 is fixed to the master wheel rotation shaft 200 or the slave wheel rotation shaft 300, and the other turntable 210 or 310 has a hole 111 in the master wheel rotation shaft 200 or the slave wheel rotation shaft 300. It is fixed and movable, and pressed and positioned by the conventional telescoping spring 121 shown in Fig. 1-8. The two turntables are opposed to each other to form a movable V-shaped groove 201 (located on the master wheel) and 301 (located on the slave wheel). Finally, as shown in FIG. 4, the special spring-shaped steel wire chain link described above is sandwiched between the V-grooves 201 and 301 of the master turntable and the slave turntable, instead of the conventional smooth or toothed i¾ belt ring, and The stepless speed governor of the present invention can be constituted by being equipped with a conventional speed governor. However, it is better to use a simpler speed governor with a simpler structure, as shown in FIGS. 1-9 and 1-10. A speed-adjusting plate 122 with a long bevel 124 is thin at the end 123 and is thick at the other end 125. The long beveled plate has a long oval shaft hole 126, which is sleeved on the rotating shaft, and is pulled back and forth by a speed-adjusting cable 128 at one end. Moving, the traction hole 127 is located at one end of the speed regulating plate 122, and the width of the V-shaped groove is adjusted by using the thickness change of the slope 124.

 The transmission mechanism of the present invention is different from the user, and is detailed below:

As shown in Figure 2-1, when the speed-adjusting steel cable 128 is fully relaxed, the special spring-shaped ring-shaped steel cable chain caught in the V-groove 201 of the main wheel turntable squeezes the movable umbrella-type turntable 210 in the main wheel turntable. Moving outward, forcing the beveled speed governor 122 to slide along the middle long elliptical shaft hole 126 to the thinnest end 123. The two disks are far away. The V-groove 201 of the main turntable is the widest. At this time, the special spring-shaped ring steel The chain link is squeezed into the innermost ring of the turntable, which is close to the axis and has the smallest torque diameter. The extra length of the spring link is bound to be accommodated by the turntable; see Figure 3-1, which results in the V from the turntable. Grooved grooves 301, The ring pressure is the smallest, and the movable umbrella turntable 310 on one side is pushed and pushed by the extension spring 121 on the outer side, and the umbrella turntable 110 is fixed to the other side. The two plates are close to reduce the width of the V-shaped groove 301 from the turntable. , Becomes the narrowest, at this time, the special spring-shaped steel wire chain link is squeezed and moved to the outer periphery of the slave wheel, and the diameter of the slave wheel torque becomes the largest, which can accommodate the torque transmitted by the reduction of the torque of the main wheel. Extra chain length; In this case, the special spring-shaped steel cable chain ring is clamped on the innermost ring of the main wheel turntable. The V-groove 201 is the widest, but the cogging 113 on both sides is the narrowest. Only one spring steel ring 118 can be squeezed into the tooth groove. However, the outer periphery of the turntable where the special spring-shaped steel wire chain link is located, the V-shaped groove 301 is the narrowest, and the tooth groove 113 is the widest. One tooth A plurality of spring steel rings 118 can be squeezed into the groove 113. If necessary, the number of teeth can be increased to improve the engagement with the spring steel rings 118. Thus, the torque of the main wheel has the smallest diameter, the fastest rotation, and the torque of the slave wheel. Largest diameter, slowest speed change, suitable for load or climbing.

 As shown in Figure 2-2, the speed-adjusting steel cable 128 is gradually tightened to the middle, and the long oval shaft hole 126 in the middle of the bevel speed-adjusting plate 122 is gradually moved along the main axis to the inclined surface 124, forcing the movable turntable 210 to move inward and shrinking. The V-shaped groove 201 of the main wheel, at this time, the special spring-shaped steel wire chain link sandwiched between it is squeezed and expanded outward, the torque diameter gradually increases from the minimum, and the cogging 113 on both sides also gradually changes. At this time, one tooth slot may be squeezed into two or three steel rings 118, and the length of the chain ring in the secondary turntable is relatively reduced; see Figure 3-2. When driving to the secondary turntable, the chain ring must compress the secondary ring. The movable umbrella-shaped turntable 310 of the turntable moves outwards, widens from the V-groove 301 of the turntable, and the special spring-shaped steel cable chain ring sandwiched therebetween moves toward the inner ring of the groove 301. It becomes smaller, and the cogging 113 on both sides also gradually narrows. At this time, the number of steel rings 118 in one cogging is reduced to three or two, and the length of the remaining steel wire chain link has been transferred into the main wheel turntable. The length of the ring and the chain ring clamped by the ring are mutually increasing, and the torque of the two is gradually approaching or equal. Constant or almost no shift.

See Figure 2-3. Continue to tighten the speed control cable 128, the slanted speed control plate 122 slides to the thickest end 125, the V-groove 201 of the main wheel is the narrowest, and the special spring-shaped ring-shaped cable is sandwiched between it. The chain ring is squeezed and expanded to the outermost periphery of the turntable, with the highest torque. The cogging 113 on both sides is the widest. Multiple steel rings 118 can be squeezed into one cogging 113 to further reduce the length of the chain ring from the turntable. See Figure 3-3. When driving to the carousel, the movable umbrella carousel 310 from the carousel is moved to the outermost side under pressure. Wide, at this time, the special spring-shaped steel wire chain link sandwiched between them is moved to the innermost ring of the turntable, close to the center of the wheel, the torque diameter is the smallest, and the cogging 113 on both sides is the narrowest. A steel ring 118 is squeezed in, and the excess chain link length is transmitted to the main wheel turntable. Like the innermost ring of the previous main wheel turn, the reverse constitutes the slowest rotation of the main wheel turn and the fastest speed change from the turntable. It is suitable for Light load or fast turn.

 According to the above process, the cycle is repeated to achieve stepless speed change. The characteristics of squeezing a ring, a second ring, a third ring, and a multi-ring respectively by using the width of the alveolar groove are the biggest advantages of the present invention and also the key point.

 In order to prevent tooth jumping, the conventional toothed disc is considered to be replaced once the tooth is worn into a triangular tooth shape. However, the present invention requires that the teeth of the turntable should be ground into a triangular tooth shape or an arc shape, or simply with the same spring wire, as shown in Figures 1-3 and 1-4. One side 116 is slightly flattened and welded into wire teeth 114 The surface is smooth and the spring steel ring is easy to squeeze in, which fully shows the characteristics and adaptability of the special spring-shaped steel wire chain link.

The embodiments of the present invention can also make the following changes: The force transmission members used in the transmission chain for pulling are the steel cables, iron chains, endurance rubber ropes or steel ball strings in the spring, not the spring itself. The main role of the spring is only The engaging piece is used to mesh with the teeth or ratchet teeth or radial (umbrella) nets on both sides of the turntable to prevent the steel cables, iron chains, endurance rubber ropes or steel ball strings from slipping in the ring. It also has protection and does not require Pull and drive, even if the spring is worn or broken into several sections, it can be used as usual. Therefore, a string of steel rings is used to replace the spring. The steel ring is penetrated by endurance rubber rope, steel ball strings, steel cables or iron chains to form another special transmission chain, that is, a string of steel ring-shaped chain links that rotates. It has the same effect as transmission and special spring-shaped steel wire chain links; and the outer sides of the spring or steel chain links can be deformed into inclined trapezoids, as shown in Figure 2-2 and Figure 3-2. 207, it is easier to embed the turntable to engage, increase the engagement surface with the turntables on both sides, and the degree of engagement is better; the thickness of the spring or the thickness of the steel ring and the spacing between the springs and the turntable teeth or ratchet teeth or radial (umbrella) mesh So that the spring or steel ring can easily be squeezed into the teeth or ratchets or radial (umbrella) mesh, and the width of the tooth or ratchet or radial (umbrella) groove should also be sufficient to squeeze into the spring or steel ring, In order to engage with each other, as for the spring or steel ring, a steel cable 117 (that is, 202 shown in Fig. 2-1 and Fig. 3-1) and an iron chain (shown in Fig. 2-3 and Fig. 3-3) 204), bead, endurance rubber rope, etc., as long as it can prevent the spring from being stretched or the steel ring from loosening and not easily broken; umbrella-shaped teeth The teeth and the alveolar (or The width and narrowness of the ratchet tooth disk and the ratchet groove) should preferably be the same width as the inside or outside of the tooth or ratchet. The narrow and wide width of the tooth or ratchet is the best. The grooves are both narrow inside and wide outside. The inclination of the turntable should be small in order to obtain the maximum difference in speed ratio with the smallest V-groove width variation. If the outer cogging is too wide, short teeth or ratchets can be added. Increase the number of teeth and increase the pulling force; the umbrella gear can be the arrangement of the aforementioned umbrella teeth and the umbrella teeth, or the aforementioned arrangement of the ratchet teeth and the ratchet grooves, or a mixed arrangement of the ratchet teeth and the ratchet grooves; The force-transmitting elements in the transmission chain, that is, the steel cables, iron chains, beads, and endurance rubber strings that are sheathed in springs or steel rings can be single strands (202 shown in Figure 2-1 and Figure 3-1), also It can be the same or different multiple strands (203 shown in Figure 2-2 and Figure 3-2). Care should be taken to disperse the welding points 119 of each strand to avoid concentration. It is too stiff and not beating smoothly. The tooth turntable group or ratchet turntable group and the movable V-shaped grooves from the wheel umbrella type turntable group or the ratchet turntable group can be clamped simultaneously The two or more transmission chains mentioned above increase the pulling force and can restrain each other to avoid loosening or slipping. As for the governor, because the structure of the master turntable group and the slave turntable group are the same, the function is the same. The slanted speed governor 122 of the present invention, or another conventional governor, can be installed on the master wheel axle 200 or the slave wheel axle 300.
