Abstract

The driving and driven gears located in the rear axle of a vehicle play a crucial role in power transmission. The bearings that support these gears are vital components whose longevity and operational conditions directly impact the efficiency of power transfer. This study focuses on enhancing the structural rigidity of both the gears and bearings by investigating the optimal spacing between two bearings on the driving gear. By extending the lifespan of these bearings, the overall performance of the main reduction unit is improved, leading to a reduction in noise and vibration, thereby enhancing the vehicle's NVH (Noise, Vibration, and Harshness) characteristics.
