Abstract

It relates to a dual wave cycloid wheel damper of a power drive. It solves the failure like poor loose teeth drive stability, and fatigability of the soft wheel of the harmonic gear. The cycloid wheel is fixed inside the major housing, with its inside mating with the roller, the wave generating wheel located in the center of the body, fixed on the input shaft, cased on the drive disk whose drive groove loaded sliding freely and fitted shaft pin and roller. The shaft pin fits with the soft ball shaft bearing on the wave generating wheel, with the rotary arm fastening with the drive plate, output shaft to form the output device. With the rotation of the input shaft, speed is distributed on the roller and cycloid wheel to reduce output. It is simple, endurable, stable and highly efficient.

Description

Technical field [0001] The invention relates to a dual-wave cycloid reducer for power transmission. Background technique [0002] The existing harmonic gear drive has the advantages of simple structure, high precision, and good stability. However, due to its high bending frequency and insufficient toughness, it is easy to fatigue and break. This is the main failure form of the transmission. The Chinese patent 86200768 raceway reducer provides a technical solution that uses a single eccentric shaft to change the structure of the harmonic gear transmission. This type of reducer has the following shortcomings: the eccentric shaft must be equipped with a balance weight to achieve the transmission purpose; under the condition of high-speed rotation, the stability is poor, the efficiency is reduced, and the accuracy is affected. Summary of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the present invention provides a double-wave cycloid reducer, ...
