Comparison of heat generation estimation methods for angular contact ball bearings

Abstract

The article reviews domestic and foreign methods of estimating heat generation in angular contact ball bearings. Models for general-purpose bearings and for aviation angular contact ball bearings are considered. Models adopted at bearing manufacturers FAG (Germany) and SKF (Sweden) are considered for general-purpose bearings. Models developed at the KAI, CIAM named after P.I.Baranov and MTU (Germany) are considered for aviation bearings. The results of heat generation obtained in testing bearings 126206 (306216 mm) and 176126 (13020033 mm) are presented. The calculated heat generation values, obtained by various methods, are compared with the experimental data. On the basis of the research the models that yield the calculated values of heat generation in ball bearings closest to the experimental data are specified. They can be used to estimate heat generation in aviation roller bearings with oil jet lubrication.
