Abstract

The invention relates to a planetary reducer. An end cover is fixed at the right end of a box body of the planetary reducer and a fixed gear is fixedly mounted at the center of the inner end surface of the end cover; a planet carrier is mounted in the middle of the inner cavity of the box body through a third bearing and a fourth bearing, and an output shaft gear is mounted at the left end of theinner cavity of the box body through a fifth bearing; an input gear shaft is concentrically inserted into central cavities of the end cover fixed gear and the output shaft gear through a first bearingand a second bearing; a first planetary gear, a second planetary gear and a third planetary gear are symmetrically mounted on the planet carrier, the first planetary gear is engaged to the fixed gear, the second planetary gear is engaged to the input gear shaft, and the third planetary gear is engaged to the output shaft gear; and power is input from the input gear shaft and is output from the output shaft gear. The planetary reducer provided by the invention is compact in structure and high in speed ratio, input and output are concentrically transmitted, and the planetary reducer has relatively high transmission precision and relatively high mechanical efficiency.

Description

technical field [0001] The invention relates to the technical field of reduction mechanisms, in particular to a planetary reduction gear. Background technique [0002] There are many types of traditional planetary reducers, but it is difficult to obtain a large speed ratio, large torque, and small size. The existing robot joint reducer has complex transmission structure, high power consumption, low efficiency and difficult maintenance. Especially in the case of limited transmission ratio and limited volume, it is difficult to adapt to high-power and high-torque transmission. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a planetary reducer, which not only has a compact structure, a small volume, and a large transmission speed ratio, but also has concentric transmission of input and output, large transmission torque, high transmission accuracy and high mechanical efficiency. Especially suitable for robot ...
