Background technology
In the design of all kinds of gearings, cycloidal planetary gear speed reducer has many advantages, such as that reduction ratio is big and small and progressively replaces The conversion equipment of speed and torque is widely used in for gear reduction unit and worm decelerating machine, and as driving or deceleration device In.But since cycloidal planetary gear speed reducer structure is sufficiently complex, requirement on machining accuracy is high, and will during design and installation Certain process gap is left, rotates that not steady enough, noise is big low with rotational efficienty when causing work, can not meet the modern times The needs of Machine Design development.
In the prior art, transmission link can significantly be simplified to carry out transmission using ball, so as to simplify internal junction Structure substantially increases reduction ratio, torque and transmission efficiency.Therefore, the cycloid speed reducer being driven using ball is also operated And it gives birth to.In transmission process, cycloid disc can only be revolved round the sun around input shaft by an anti-rotation mechanism limitation and be unable to rotation, and input Axis high-speed rotation limits eccentric disc certainly by anti-rotation mechanism then is only translatable;At this point, cycloid disc and power output device are led to Cross ball engagement so that speed is shunted, and the rotation of deceleration propulsion power output device exports so as to which output shaft slows down.
However, the hypocycloid raceway and epicycloid raceway of existing power output device are curtate cyclod list arc raceway Or curtate cyclod duplex circular ares profile race, and intensive steel ball is clipped between hypocycloid raceway and epicycloid raceway.Due to inputting For axis when input rotates at a high speed, the transmission performance of cycloidal ball is decided by the shape of two cycloid orbits, and the steel that the patent is intensive Pearl forms certain phase difference in hypocycloid raceway and epicycloid rolling path rolling, the rotational angle for output of having cancelled out each other, so as to The reduction ratio of speed reducer is caused to reduce, reduces transmission efficiency.Meanwhile existing power output device is suitable only for single axis Cycloid speed reducer, and deceleration output can not be carried out as the component of more crankshaft deceleration machines;Moreover, it can not also realize speed reducer Two-sided output causes the output face that speed reducer is distinguished in speed reducer and output equipment are using installation process, subtracts so as to reduce The convenience and versatility that fast machine uses.
The content of the invention
It is an object of the invention to overcome shortcoming and deficiency of the prior art, a kind of simple in structure and difficulty of processing is provided The power output device of small more bent axle cycloid speed reducers, which changes the movement locus of ball, so as to carry The transmission performance of high ball, and then effectively improve the reduction ratio and transmission efficiency of speed reducer.Meanwhile the power output device can be real Now speed reducer is two-sided can install with output equipment, and so as to improve convenience and the versatility that speed reducer uses, it is suitable for more Power output part is used as in bent axle cycloid speed reducer.
