Service life and lubrication conditions of different grease types in high-speed rolling bearings

摘要

This paper deals with the influence of lubricating grease composition on grease service life and tribological performance characteristics in high-speed rolling bearings. First of all the test rig including the measuring system used to determine the lubricant film thickness in operation as well as the greases used in the study will be explained. Experimental results will then be used to analyse the influence of thickener type and contant, base oil type and viscosity and anti-oxidants on grease service life, lubricant film thickness, bearing temperature and friction torque.
