Novel planetary circular tooth type speed reducer

Abstract

The invention discloses a novel planetary circular tooth type speed reducer. The speed reducer comprises a cycloid shell, an input end cover, a first input end bearing, an input end flange, a second input end bearing, a first cycloidal gear, a second cycloidal gear, a hinge pin, an eccentric shaft, a first output end bearing, an output flange, a second output end bearing and an output end cover, outer teeth distributed in an encircling mode are arranged on the outer side walls of the first cycloidal gear and the second cycloidal gear respectively, inner teeth distributed in an encircling mode are arranged on the inner wall of the cycloid shell, and rolling needles are arranged between the outer side walls of the first cycloidal gear and the second cycloidal gear and the inner wall of the cycloid shell. Accordingly, the overall structure supported by the two covers, the two flanges and the two bearings is adopted, and positioning of the output end cover and the cycloid shell uniformly adopts an inner hole of the input end cover; by means of the structure, the stability of the speed reducer is better, the rigidity is higher, bearing is larger, and the machining technology of parts is better.

Description

technical field [0001] The invention relates to the technical field of reducers, and more specifically, relates to a novel planetary gear reducer. Background technique [0002] The reducer plays the role of matching speed and transmitting torque between the prime mover and the working machine or the actuator. The reducer is a relatively precise machine. The purpose of using it is to reduce the speed. According to the number of transmission stages, it can be divided into single-stage And the shape of the multi-stage reducer can be divided into cylindrical gear reducer, bevel gear reducer and conical-cylindrical gear pulley reducer; according to the layout of the transmission, it can be divided into expansion type, shunt type and coaxial type reducer device. The reducer is an independent component composed of gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid shell. It is often used as a reduction transmission device between the prime mover a...
