Diagram).Here, the function of being realized according to each above-mentioned building block, can also be referred to as gear unit by bevel gear 30；Will cone
Gear 50 and spur gear 60 are collectively referenced as output unit；Bevel gear 40, worm gear 70, worm screw 80 and servomotor is (not shown) altogether
With referred to as speed adjustment unit.The structure of above-mentioned building block is described in detail below with reference to Fig. 1.
According to the direction shown in Fig. 1, driving shaft 10 is fixed in bearing block 90, and driving shaft 10 is the power of whole device
Input, wherein, driving shaft 10 can be driven by motor to be rotated, and motor is not shown in Fig. 1.
Driving shaft 10 and the connection of the cross of differential shaft 20.In one embodiment, it is provided with axle on driving shaft 10
Hole, differential shaft 20 is connected through above-mentioned axis hole with driving shaft 10；In another embodiment, it is provided with axle on differential shaft 20
Hole, driving shaft 10 is connected through above-mentioned axis hole by way of axle key coordinates with differential shaft 20.Above two embodiment, equal energy
Realize that differential shaft 20 rotates entirely around driving shaft 10.Driving shaft 10 and differential shaft 20 are that square crossing connects in the embodiment
Connect, certainly, in other implementations, driving shaft 10 and differential shaft 20 can also be that oblique is connected.
Bevel gear 30 is respectively arranged with the two ends of differential shaft 20, bevel gear 30 can be by bearing (not with differential shaft 20
Diagram) it is connected, bevel gear 30 can rotate around the axial direction of differential shaft 20.
According to the direction shown in Fig. 1 can be seen that with bevel gear 30 and meanwhile engage be connected have on the left of bevel gear 50 and
The bevel gear 40 on right side, the bevel gear 50 in left side is introduced first below.
Together with bevel gear 50 is fixedly and coaxially connected with spur gear 60, and bevel gear 50 and spur gear 60 can also pass through one
Bearing (not shown) is connected with main shaft 10, above by the agency of mistake, and driving shaft 10 is power intake, the spur gear 60 of the position
For specific clutch end.In addition, two bevel gears 30 of bevel gear 50 simultaneously with the two ends of differential shaft 20 are while the company of engagement
Connect.
According to the direction shown in Fig. 1, in the right-hand member of bevel gear 30, bevel gear 40 and worm gear 70 are fixedly and coaxially connected one
Rise, and bevel gear 40 and worm gear 70 can be connected by a bearing (not shown) with main shaft 10, bevel gear 40 is while and differential shaft
Two bevel gears 30 at 20 two ends engage connection simultaneously.
Worm gear 70 is connected with the engagement of worm screw 80, and what is be connected with worm screw 80 also has servomotor (not shown), the servo at this
Motor primarily serves the effect of speed adjustment, by adjusting the steering of servomotor, and then final realize adjusts the straight of output end
The effect of the rotating speed of gear 60.
The structure of the velocity adjustment apparatus of the embodiment of the present application offer is mainly provided above, below will be to its operation principle
It is introduced.
As it was previously stated, driving shaft 10 is power intake, spur gear 60 is clutch end, in the course of work, if cone
Gear 40 and worm gear 70 keep not rotating, then output end spur gear 60 can keep with driving shaft 10 be adapted speed and constant speed transport
Turn.
When carrying out speed adjustment, if turn of (indirect) rotation direction for driving worm gear 70 of servomotor and driving shaft 10
When dynamic direction is consistent, the rotating speed (can be linear velocity) of output end spur gear 60 increases., whereas if the rotation direction of worm gear 70
When opposite with the rotation direction of driving shaft 10, the rotating speed reduction of output end spur gear 60.The change of the rotating speed of output end spur gear 60
Amplitude depends on the rotating speed size of worm gear 70.The crawl of small electromotor, step-operated can realize the micro- of output end spur gear 60
Velocity compensation is measured, continuously running for small electromotor can realize the continuous velocity compensation of output end spur gear 60.
In speed adjustment unit in the embodiment, bevel gear 40 drives rotation by worm gear 70 and worm screw 80, at least includes
There is following three aspect：
First, worm gear and the auto-lock function of worm screw (lead angle of worm screw 80 is less than the equivalent friction angle that worm gear 70 takes turns between cog),
So, when being adjusted without speed, bevel gear 40 and worm gear 70 are by remains stationary, because worm gear 70 can not drive worm screw 80 to revolve
Turn.
2nd, the characteristics of the big speed ratio of worm and gear, i.e., worm screw 80 is that speed adjustment can be achieved with less dynamic rotation
Function；
3rd, while worm and gear realizes big speed ratio, because worm screw 80 can realize that higher speed is rotated, and band
Dynamic worm gear 70 is easy to implement micro, the accurate adjustment to the speed of output end spur gear 60 with less speed transmission.
Certainly, in other implementations, bevel gear 40 can also be driven by other actuating units, such as sprocket wheel is passed
Dynamic, V belt translation, Spur Gear Driving.When using Spur Gear Driving, what is be connected with spur gear can also have reductor and reductor
Servomotor of connection etc..In this kind of embodiment, when carrying out speed adjustment, servomotor drives reductor, spur gear successively
And bevel gear 40 rotates, realize and the rotating speed of output end spur gear 60 is adjusted.When being adjusted without speed, servomotor
Stop the rotation, reductor will control connected spur gear and bevel gear 40 to remain static, the meeting of output end spur gear 60
Keep with driving shaft 10 be adapted speed and constant speed operate.
The velocity adjustment apparatus provided using the embodiment of the present application, by set with the differential shaft of driving shaft interconnection,
The gear unit set in the end of differential shaft, the output unit being connected with gear unit rotation, and, rotated with gear unit
The speed adjustment unit of connection, due to the above-mentioned spatial relation of driving shaft, differential shaft and gear unit, driving shaft is exported
Power travel direction conversion, so, adjustment unit is simultaneously participated in driving shaft to the power between output unit
In output procedure, when carrying out speed adjustment, driving shaft still keeps stable power resources, passes through adjustment unit of regulating the speed
Velocity of rotation, you can realize and be adjusted to the speed of output unit.
In addition, whole velocity adjustment apparatus is simple in construction, compact, manufacturing cost is relatively low；Watching in speed adjustment unit
Crawl type micro speed governing can both have been realized by taking motor, can also realize continuous speed adjustment；The embodiment uses mechanical differential formula speed
Adjustment mode, stability, the reliability of transmission system is higher.
The velocity adjustment apparatus that the embodiment of the present application is provided, be particularly suitable for use in the mechanical of the multiple loads of same motor drag
Transmission mechanism, and each load movement needs synchronism to adjust.
In order to introduce the velocity adjustment apparatus of the embodiment of the present application offer in further detail, below with reference to application scenarios pair
It describes in detail.
