The Effects of Grease Filling Amount on Temperature Performance of High-Speed Sealed Angular-Contact Ball Bearings

摘要

More than 80 percentages of high-speed sealed angular-contact ball bearings are lubricated by grease. The grease filling amount has a great influence on bearing performance and service life. The static space ratio λ_s and movement space ratio λ_d were analyzed and calculated in this paper. Bearing temperature performance tests were conducted using different amounts of filling grease. The temperature performance of bearings with different grease was compared under different working conditions. The optimum grease filling amount of this kind of bearings is obtained through experiments. The conclusion can provide reference for bearing application.
