Description
Technical field
The utility model relates to a kind of motor, especially relates to a kind of engine without connecting bar and crankshaft.
Background technique
At present, known motor all is to be converted to by the to-and-fro motion that crankshaft connecting rod type mechanism imports power to rotatablely move, but in the practical application, the fretting wear loss of crankshaft connecting rod type driving mechanism is too high, thereby transmission efficiency is lower, and the raising of the total efficiency of motor also is a greater impact.There is research to indicate, the friction power loss of piston connecting bar system can account for 75% of entire internal combustion engine mechanical loss, and why it exists so high frictional loss and loss in efficiency, main cause is: 1, during engine operation, piston crank mechanism directly contacts with high temperature and high pressure gas, and the friction power loss of cylinder sleeve-piston ring is very big; 2, the special mode of transfer force of crankshaft ﹠ connecting also makes the frictional loss of each revolute joint of crankshaft ﹠ connecting strengthen, and the result causes the machinery driving efficiency of motor and the raising of total efficiency to be restricted; 3, owing to use crankshaft ﹠ connecting, the fretting wear of parts such as the piston ring of motor, cylinder sleeve, connecting rod, bent axle is violent, makes the life-span of motor driving parts also greatly reduce.During 4, owing to the crankshaft-link rod engine operation, piston assembly and connecting rod small end do reciprocating linear motion in cylinder and can produce reciprocal inertia force, and the crank, crank pin and the connnecting rod big end that depart from crankshaft center line are made circular movement around crankshaft center line and then can be produced rotating inertia force.The synergy of above-mentioned reciprocal inertia force and rotating inertia force can make motor produce violent vibration, has also strengthened the distortion and the degree of wear of motor parts simultaneously.This shows, current on motor widely used crankshaft ﹠ connecting, it is the raising of limiting engine transmission efficiency not only, also has influence on simultaneously the life-span of driving parts, the low excessively waste that causes the energy of efficient, the life-span crosses the low waste that then causes resource.
The model utility content
Technical problem to be solved in the utility model is at above-mentioned deficiency of the prior art, a kind of engine without connecting bar and crankshaft is provided, it is simple and reasonable, frictional loss is low and transmission efficiency is high, can replace the type of belt drive that traditional crankshaft ﹠ connecting realizes that it will be realized fully.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of engine without connecting bar and crankshaft, comprise cylinder and link to each other with described cylinder and by the engine drive mechanism that it drives, it is characterized in that: described engine drive mechanism comprises supporting frame, drive the power lever of doing straight reciprocating motion by described cylinder, two motive power wheels that lay respectively at the power lever left and right sides and rotate by the power lever drive, drive two drive wheels rotating by described two motive power wheels respectively and drive and be sleeved on the transmission shaft and drive the follower that transmission shaft rotates by described two drive wheels; Between described two motive power wheels and two drive wheels or between two drive wheels and the follower two overrunning clutchs are installed, the operating state of described two overrunning clutchs is opposite; Described two motive power wheels are set on two axles that are installed on the supporting frame, transmission shaft be installed on the supporting frame and its with supporting frame between be connected by bearing.
The kind of drive between described motive power wheel and the power lever is the gear rack kind of drive or the friction wheel friction lever kind of drive.
The kind of drive between described drive wheel and the follower is gear transmission, sprocket driving or belt pulley transmission.
Described two drive wheels correspondence respectively are sleeved on described two axles, between the motive power wheel and follower that described overrunning clutch is installed on each to be installed.
The kind of drive between described motive power wheel and the described drive wheel is gear transmission, sprocket driving or belt pulley transmission.
The corresponding respectively top and the bottom that are sleeved on follower of described two drive wheels, described overrunning clutch correspondence is installed between two drive wheels and the follower.
Described follower is the clutch bushing of described overrunning clutch.
The piston or the piston rod of described power lever and described cylinder join.
The utility model compared with prior art has the following advantages, 1, simple and reasonable, frictional loss is little and transmission efficiency is high: under the condition that does not adopt traditional crankshaft ﹠ connecting, by the direct kind of drive of power lever and motive power wheel, the power-converting of linear reciprocating motion is become unidirectional lasting rotation motion and power; Owing to do not adopt traditional crankshaft ﹠ connecting, the side direction impacting force that connecting rod produces piston when also just having avoided crankshaft ﹠ connecting work, thereby improved the operating conditions of piston greatly, make the frictional loss between piston and the cylinder body greatly reduce, piston and cylinder body eccentric wear phenomenon can not take place yet again; Also avoid simultaneously the frictional loss of crankshaft ﹠ connecting revolute joint, in a word, it has been avoided because of the excessive frictional loss of using crankshaft ﹠ connecting to produce, thereby makes the frictional loss of motor mechanisms littler, machinery driving efficiency is higher, makes that also the total efficiency of motor is higher; That is to say, under the identical situation of output work, the energy of consumption is reduced, thereby realize energy saving, reduce consumption and reduce the effect of discharging.2, owing to do not adopt bent axle, linkage mechanism, the crank, crank pin and the connnecting rod big end that have not also just had to depart from crankshaft center line are made the rotating inertia force that circular movement produces around crankshaft center line, thereby the vibration during engine operation greatly alleviates; Simultaneously, owing to there have not been driving parts such as bent axle, connecting rod, the wearing and tearing of these parts also just no longer exist, and the bulk life time of motor driving parts has obtained bigger raising; 3, the application is wide: not only can effectively replace the crankshaft ﹠ connecting that tradition is used on internal-combustion engine, the external-combustion engine, but also can be used as the power conversion mechanism of wave motor or generator and jolt vibration engine or generator, in addition, it can also external pressurized gas such as pressurized air etc. and directly produce rotating power, and power performance is better; 4, can adopt non-petroleum product to do fuel, as adopting the power fuel as motor such as ethanol, gunpowder, coal.To sum up, the utility model is simple and reasonable, frictional loss is low and transmission efficiency is high, can replace the type of belt drive that traditional crankshaft ﹠ connecting realizes that it will be realized fully, it is under the situation that does not adopt crankshaft ﹠ connecting, convert the to-and-fro motion of power lever the folk prescription of follower to continuing rotation, can directly drive the rotational motion of load, realize higher machinery driving efficiency, thereby make the total efficiency of motor higher.The alternative traditional law of Crankshaft-Link mechanism in engine of this mechanism is widely used in explosive motor, external-burning engine, gunpowder type engine, wave motor, the motor that jolts etc. and linear reciprocating motion need be converted to folk prescription to the occasion that continues rotation motion.
