New energy passenger car gearbox bearing materials and Key technical control of thermal processing

New energy passenger car transmission bearings include deep groove ball bearings, angular contact bearings, four-point contact bearings, tapered roller bearings,  cylindrical roller bearings.

Working characteristics of new energy vehicle bearings: high speed, high load, low friction, low noise, long life.

In order to improve the service life of new energy vehicle gearbox bearings, in addition to using computer simulation software for simulation design on the bearing structure, low-friction optimization design is carried out on the bearing raceway, microscopic modification, and early failure caused by stress concentration are reduced; the interior of the bearing is simulated Stress cloud map, calculation of maximum contact stress, friction torque and technical parameters such as stiffness, efficiency, preload, etc., it is also necessary to control the key factors that determine the life of the bearing: material, thermal processing technology.
