Skidding and spinning investigation for dry-lubricated angular contact ball bearing under combined loads

Abstract Sliding and spinning behaviors significantly affect the performance of rolling bearings, especially for dry-lubricated micro macro sliding may lead to increased wear solid lubricating film. A unified contact tribology analytical model is proposed angular ball bearings (ACBBs) considering extreme conditions including high combined loads effects. comprehensive solution framework ensure robustness under different loading conditions. Equilibrium equations are solved study effects friction coefficients, rotating speeds, on skidding characteristics ACBB. The results show that Further analysis reveals mechanism related interaction between kinematical motion traction forces. developed proved more accurately predict bearing tribological behavior as it discards raceway control hypothesis considers macro/micro-slipping, creepage, self-spinning motions ball, which validated using both existing pure axial ACBB classical Jones—Harris model. would provide some guidance structure lubrication design ACBBs.
