Temperature Field Analysis and Temperature Control of Vacuum Ultra High Speed Angular Contact Ball Bearings

In order to investigate the temperature field distribution of bearings under vacuum and ultra-high-speed conditions and put forward a good temperature control method, this paper adopts the local method to analyse and calculate the temperature of various parts of the bearing, and establishes a simulation model of the bearing by using the finite element analysis method of ANSYS, and carries out a test on the experimental platform of the vacuum and ultra-high-speed motors, which proves that the temperature of the rollers is the highest, followed by the inner-ring raceway and the outer-ring raceway, and provides effective theoretical methods for the analysis of the temperature field of the angular contact ball bearing under the conditions of high vacuum and high speed; the temperature of the bearing as a whole is controlled by the structure of the installed water jacket.
