Method for adjusting axial endplay gap of closed main reducer driving gear

Abstract

The invention provides a method for adjusting an axial endplay gap of a closed main reducer driving gear, and relates to a method for adjusting an axial endplay clearance of a bearing. The method comprises the steps as follows: outer rings of an inner bearing and an outer bearing and an inner ring of an inner bearing of an axle drive bevel pinion are firstly pressed in position, and a standard shim is preassembled between the inner bearing and the outer bearing; and the inner ring of the outer bearing is pressed to push the axle drive bevel pinion to move up and down, displacement of up-and-down movement of the axle drive bevel pinion is measured, a thickness value of an adjusting shim is figured out according to the displacement of up-and-down movement of the axle drive bevel pinion and the thickness of the standard shim, the standard shim is replaced by the adjusting shim, the axle drive bevel pinion is pulled to be assembled in position, the inner ring and a flange of the outer bearing are assembled, and whether the start-up force is qualified is detected. According to the invention, the accurate shim thickness is measured and figured out on the basis of actual endplay amount of the inner bearing and the outer bearing, mounted on a main reducer casing, of the axle drive bevel pinion, a reasonable axial endplay gap of the driving gear bearing can be guaranteed, the manufacturability is reasonable, the operation is convenient and fast, the service life of a main reducer is prolonged, the assembly efficiency is high, and the quality is stable and reliable.

Description

technical field [0001] The invention relates to a method for adjusting the axial movement clearance of a bearing, in particular to a method for adjusting the axial movement clearance of a closed main reducer and main tooth. Background technique [0002] Closed main gear reducer Since the main reducer housing and the rear axle housing are cast in one piece, it is difficult to install the active bevel gear in place in a semi-enclosed space, and it is difficult to adjust the axial movement clearance of the main gear bearing. After assembly, it is difficult to detect the main gear start The torque is often out of tolerance. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a closed-type method for adjusting the axial movement clearance of the main reducer and the main gear, which can be quickly and easily press-fitted and can accurately adjust the axial movement clearance of the bearing, so as to improve the assembly e...
