Abstract

The invention provides an integrated robot joint mechanism. The integrated robot joint mechanism comprises an output end body, a pin gear shell of an RV reducer, a fixed end body, an integrated motor,an output disc frame of the RV reducer, an eccentric shaft, a planet wheel, an angular contact ball bearing and a cycloid wheel, wherein the integrated motor comprises a motor main body and an inputshaft connected with the motor; the integrated motor and an RV reducer pin gear shell are combined into an integrated unit; the pin gear shell of the RV reducer of the integrated unit is fixedly connected with the fixed end body; the output disc frame of the RV reducer is connected with the output end body; and the eccentric shaft comprises a cam, an eccentric shaft concentric circle, a tapered roller bearing and a needle roller retainer. In the technical field of RV speed reducers, the problems of large noise, complex debugging and high installation precision requirement of an existing robotjoint structure are solved by adopting the integrated robot joint mechanism.

Description

technical field [0001] The invention relates to the technical field of RV reducers, in particular to an integrated robot joint structure. Background technique [0002] RV reducer is a new type of reducer developed on the basis of cycloidal pinwheel transmission. There are two stages of deceleration structure: the first stage is a planetary deceleration structure, and the second stage is a cycloidal pinwheel deceleration structure. It has the advantages of high rigidity, high precision, high torque, and high transmission efficiency. It has smaller volume and greater overload capacity than the simple cycloid planetary transmission. In the transmission mechanism of Japanese robots, it has been used to a large extent Gradually replace the simple cycloid planetary transmission and harmonic transmission. [0003] figure 1 It is a schematic diagram of the structure of the RV reducer. Main components: pin gear housing 2, eccentric shaft 6, planetary gear 7, input shaft 41, outpu...
