Analysis for Thermal Characteristics of High-Speed Angular Contact Ball Bearing under Different Preload

摘要

A large amount of heat is produced due to the friction between components within the bearing, resulting in an increase in temperature of the bearing system. The value of the preload directly affects the temperature of the bearing, and will affect the performance of bearing. Based on ball bearing of quasi-statics and thermal analysis, the heat generation of the high speed angular contact ball bearing is calculated and analyzed under different preload, rotation speed and contact angle. The temperature distribution of the bearing under steady state condition is obtained by using ANSYS for the numerical simulation of the bearing different conditions, and the influence rule of preload on heat generation of bearing is given. The research results provide a reference for the temperature distribution of rolling bearing and its application research.
