Calculation of Bearing Elastic Deformation Temperature Rise Simulation Research

Abstract

High-end equipment bearings require long life, high precision, and high stability, and their influencing factors need to be thoroughly and systematically investigated. Temperature increase will greatly promote the organizational structure changes, which will directly affect the fatigue life of bearings. This paper adopts a numerical simulation calculation method to simplify the bearing model in the alternating stress elastic deformation of the temperature change. Based on the finite element analysis method to establish the steady-state thermal analysis model of the bearing, the simulation calculation results show that compared with the load change, the temperature rise caused by the speed change is more drastic, and the effect of speed on the bearing temperature is more obvious.
