Dynamics-Based Calculation of the Friction Power Consumption of a Solid Lubricated Bearing in an Ultra-Low Temperature Environment

Abstract

Bearings operating in ultra-low-temperature environments are commonly lubricated with solid lubricants. This study first focused on measuring the traction coefficients of molybdenum disulfide (MoS2) solid lubricant under various working conditions. Based on this data, the friction power consumption of the bearings was calculated and analyzed using a dynamic model. Additionally, experimental verification of the bearing friction power consumption in ultra-low temperature environments was conducted. The research findings will serve as a foundation for the application of solid lubrication bearings in ultra-low-temperature environments.
