The problems of the matched tapered roller bearing preloads in the bearing assembly of bevel drive pinion assembly of truck are studied in this paper. The study includes the relation among the bevel drive pinion bearing preloads, axial displacement and locknut screwing moment and the relation between the start-up frictional moments and axial displacement. And the bearing preloads moment and start-up friction moment are calculated. Based on these researches, the equipment of automatic bevel drive pinion assembly is developed, which has the function of automatically measuring screwing moment and start-up friction moment. The equipment works smoothly after being used and solves the technical difficulty of the bevel drive pinion assembly successfully, which improves the assembling quality and efficiency of bevel drive pinion assembly.
