Abstract

The invention relates to a planetary reducer. The planetary reducer comprises a shell, a planetary reduction set, an output shaft and a rear end cover, wherein the planetary reduction set is arranged in a cylindrical space of the shell and comprises a planet carrier and a planetary gear which is rotatably mounted on positioning pins of the planet carrier. According to the planetary reducer, first protrusions capable of abutting against gaskets are formed on the side, close to the adjacent gaskets, of the planetary gear, the contact area of the planetary gear and the adjacent gaskets is reduced through the first protrusions, friction is reduced, and then noise generated when the planetary reducer works is reduced.

Description

technical field [0001] The invention relates to a reducer, in particular to a planetary reducer. Background technique [0002] The planetary reducer is a versatile industrial product that can reduce the speed of the motor while increasing the output torque. It generally includes structures such as an inner ring gear, a planetary carrier, a planetary gear, a gasket, and an output shaft. During the working process of the planetary gearbox, the planetary gear moves relative to its adjacent gasket. [0003] However, the planetary gears are in contact with the adjacent gaskets in a large area, resulting in relatively large noise generated when the planetary gears move relative to the gaskets, and spread to the outside of the planetary reduction box. Contents of the invention [0004] In view of the above problems, the present invention is proposed to provide a planetary reducer that overcomes the above problems or at least partially solves the above problems. [0005] The pla...
