Friction-Induced Heating in Axially Loaded Ball Bearings

Abstract

This paper compares theoretical and experimental results on the friction-induced heating in thrust-loaded ball bearings at constant speed. Heat transfer and friction heat-generation models are developed for the bearings using computer techniques. The comparisons indicate that the models are reasonable since the predictions are within ±10 percent of the measured values. More work is needed, however, before a more accurate prediction technique will be available.
