Cycloidal-pin wheel or small tooth difference type differential speed reduction device and speed reducer

Abstract

The invention relates to the field of mechanical transmission and the field of mechatronics, in particular to the fields of speed reducers, robots and biomimetic robots. Similar cycloidal-pin wheel and small tooth difference differential speed reduction devices or speed reducers in the prior art are reformed, so that acting force or counter-acting force of transmission parts is balanced in the axial direction, and meanwhile centrifugal force generated by planetary motion of the transmission parts is balanced, so that the vibration problem of speed reduction devices and speed reducers of the same kind in the prior art is solved; the problem that in the speed reduction devices and speed reducers in the prior art of the same kind, part of bearings need to additionally bear acting force two times of acting force borne by eccentric bearings on a cycloidal-pin wheel speed reducer or a small tooth difference speed reducer with the same output torque is solved; and use of bearings is reduced. According to the technology, the effects which are not lower than the effects capable of being achieved by the prior art of the same kind can be obtained in practical application, and meanwhile all the beneficial effects are obtained without generating technical conditions of new problems.

Description

technical field [0001] The invention relates to the field of mechanical transmission and electromechanical integration, in particular to the fields of reducers, robots and bionic robots. Background technique [0002] Among the existing disclosed technologies, the Chinese patent application with the publication number CN112013094A partially solves the vibration problem of the similar differential reducer disclosed in the applications with the publication numbers CN109268452A, CN111005987A, CN111022588A, etc., but this type of invention application In the technical solution, there is the problem that the eccentric bearing needs to withstand the force borne by the eccentric bearing on the cycloidal pin gear reducer or the reducer with a small tooth difference that is twice the same output torque, and other bearings in this reducer The problem of bearing an additional force equal to the above-mentioned force has not been solved.
