Dynamic Modeling of Local Defect Angular Contact Ball Bearing Considering Retainer Action under Elasto-fluid Lubrication

The traditional method mainly considers the centrifugal force and contact force when modeling the rolling bearing with local defects under the condition of EHL. It ignores that the retainer is the core part of the bearing. Due to the hydrodynamic pressure effect of the lubricant, there is interaction between the retainer and the guide ring. To solve this problem, a dynamic model of local defected angular contact ball bearing under EHL is proposed.
