Abstract

The invention relates to the technical field of stress calculation, and provides an RV reducer main bearing stress analysis and calculation method for a robot, and the method comprises the steps that:1, the internal stress analysis of an RV reducer is carried out; 101, the contact acting force of a cycloidal gear and a pin wheel is obtained; 102, the contact acting force of the cycloidal gear anda crankshaft is obtained; 103, the contact acting force of the crankshaft and a flange plate is obtained; 2, external stress analysis is conducted on the RV speed reducer; and 3, a main bearing of the RV speed reducer is optimally designed. The reasonability and the analysis efficiency of the stress analysis amount of the main bearing can be improved.

Description

technical field [0001] The invention relates to the technical field of force calculation, in particular to a force analysis and calculation method for a main shaft of an RV reducer for a robot. Background technique [0002] The RV reducer is a two-stage reduction transmission mechanism composed of planetary gear transmission and planetary cycloid transmission. It has the advantages of large transmission ratio, small size, high rigidity, large bearing capacity, high transmission accuracy and high transmission efficiency, and is widely used in industry. In the robot joint drive device. The main bearing is a key supporting component of the RV reducer, and its performance and life directly affect the performance, reliability and safety of the reducer. The main bearings used in Japanese RV reducers are provided by companies such as NSK and NTN. The related technologies are kept secret, and the specific parameters and processes are unknown. However, domestic research on RV reduc...
