Abstract

The invention relates to the technical field of speed reducers, and provides an RV speed reducer and a robotic.The RV speed reducer comprises an output frame, a supporting flange, a first-stage speed reducing mechanism, a second-stage speed reducing mechanism and a pin wheel housing, a center connecting shaft and a circumferential connecting shaft are arranged on the output frame, and a center through hole and a circumferential through hole are formed in the supporting flange; the first fastener penetrates through the central through hole and the central connecting shaft, and the second fastener penetrates through the circumferential through hole and the circumferential connecting shaft, so that the output frame is connected with the supporting flange; a planetary gear of the first-stage speed reducing mechanism is mounted on the supporting flange; the two ends of a crankshaft of the second-stage speed reduction mechanism are connected with a planetary gear and an output frame correspondingly, an upper cycloidal gear and a lower cycloidal gear are rotationally connected with a first eccentric part and a second eccentric part of the crankshaft correspondingly, and the upper cycloidal gear and the lower cycloidal gear are sleeved with a pin gear housing and connected with the upper cycloidal gear and the lower cycloidal gear in a meshed mode. The RV speed reducer has the effects of being large in torsional rigidity and high in bearing capacity.

Description

technical field [0001] The present application relates to the technical field of reducers, in particular, to an RV reducer and a robot. Background technique [0002] The RV reducer is a reducer developed on the basis of the traditional pendulum planetary transmission. It usually includes a first-stage cylindrical gear planetary reduction mechanism and a second-stage cycloidal pinwheel reduction mechanism. It has small size, light weight, and transmission With a series of advantages such as large specific range, long life, stable precision, high efficiency, and smooth transmission, it is widely used in robotics and other fields. [0003] The existing RV deceleration device has the disadvantages of small torsional rigidity of the output structure and weak bearing capacity. Contents of the invention [0004] In view of the problems existing in the above-mentioned prior art, the purpose of the embodiment of the present application is to provide an RV deceleration device and a...
