Reducer gasket, reducer and method for determining thickness of reducer gasket

Abstract

The invention discloses a reducer gasket, a reducer and a method for determining the thickness of the reducer gasket, and particularly relates to the technical field of transmission equipment. The reducer gasket comprises an integrated circular sheet and a plurality of connection through holes formed in the circular sheet, wherein the circular sheet is arranged between a planet carrier and a rigiddisk and located in a sunken table formed by the inner circle of a main bearing matched with the rigid disk and the end face of the rigid disk; and the circular sheet is separated from a cycloidal gear of the reducer. According to the reducer gasket, the same pretightening force of a bearing system in the reducer can be guaranteed, a main bearing system is prevented from tilting, the reducer is in the optimal operating state advantageously, and the service life is prolonged.

Description

technical field [0001] The invention relates to transmission equipment, in particular to a reducer gasket, a reducer and a method for determining the thickness of the reducer gasket. Background technique [0002] RV reducer is one of the core components of robot transmission. Compared with other reduction methods, RV reducer has the advantages of large reduction ratio, coaxial transmission, high transmission accuracy, high rigidity, and compact structure. It is widely used in electronics, aviation, etc. Aerospace, robotics and other industries. The robot RV reducer has a complex structure, including cycloidal wheel, crankshaft, pin gear housing, planetary carrier, rigid disc and other components. Among them, the planet carrier and the rigid disc can be combined into a planet carrier rigid disc assembly, which is an important part of the robot RV reducer; The inner bearing chamber is set inside the rigid disc assembly of the frame to install the roller bearing and the crank...

AI Technical Summary

Problems solved by technology

When applying preload to the bearing system, it is necessary to ensure that the rigid disk of the planetary carrier is in a state of fit in advance. However, due to the inconsistent assembly height of the currently used bearings, it is impossible to ensure that the preload of the bearing system in each reducer is the same, resulting in bearings Deviating from the best working life state, affecting the bearing life and overall machine performance

like figure 1 As shown, in order to solve the above-mentioned problems, in the prior art, the inconsistency of the assembly height is generally compensated by adding a small spacer (19) respectively on the six supporting columns, but a plurality of small spacers (19) are assembled separately, and the assembly The process is cumbersome, and because the thickness of each gasket (19) cannot be absolutely consistent, there is a difference in thickness between each gasket (19), which will cause the bearing system to tilt during assembly, affecting the normal operation of the reducer
