Abstract

The invention discloses a fully sealed integrated RV speed reducer which comprises a second grade cycloidal-pin wheel speed reducing structure composed of a pin wheel housing, a cycloid line wheel and a roller pin, a first grade planet speed reducing mechanism composed of an input shaft and a planet wheel, and an output plate rack, wherein an output end cover is arranged at the outer side of the output plate rack and the output end cover is fixed on the output plate rack of the RV speed reducer through a screw; a plurality of through holes being corresponding to the output threaded holes formed in the output plate rack are formed in the output end cover, the pin wheel housing is connected with an input flange, an input shaft support bearing is arranged between an input end flange and the input shaft, and a framework oil seal is arranged between the input end flange and the input shaft; a plurality of threaded holes used for mounting a servo motor are formed in the input end flange. The fully sealed integrated RV speed reducer is reasonable in structure, good in work performance, and has fully sealed structure.

Description

technical field [0001] The present invention relates to an RV reducer. Background technique [0002] RV reducer is a new type of reducer developed on the basis of cycloidal pinwheel transmission. There are two-stage deceleration structures: 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. Compared with the simple cycloid pinwheel planetary transmission, it has a smaller volume and greater overload capacity. In the transmission mechanism of Japanese robots, it has been largely used. Gradually replace the simple cycloidal pinwheel planetary drive and harmonic drive. [0003] figure 1 It is a schematic diagram of the structure of a traditional RV reducer. Main parts: pin gear housing 1, eccentric shaft 2, planetary gear 3, input shaft 4, output disc frame 5, angular contact ball bearing 6, cycloidal...
