Adjuster for conical bearing of differential

Abstract

The invention provides an adjuster for a conical bearing of a differential. The adjuster for the conical bearing of the differential comprises a device body; a step through hole is formed in a central shaft of the device body for mounting a bearing outer ring of the conical bearing; the step through hole comprises a thick hole and a fine hole; a rotary transmission shaft driving a tire to rotate passes by the step through hole and the bearing outer ring is arranged in the thick hole; external threads are arranged at the outer surface of the device body for being matched with internal threads arranged on a shell of the differential. According to the adjuster for the conical bearing of the differential, the external threads for being matched with the internal threads on the shell of the differential are arranged on the outer surface of the device body, and the starting torque of the conical bearing of the differential of a speed changer can be adjusted by adjusting the screwing down length of the external threads, so the adjuster for the conical bearing of the differential does not need massive test equipment for measurement, and is simple in process and fast to mount; when an axial gap is enlarged, adjustment can be performed by changing the screwing down length of the external threads, and the service life of the conical bearing is prolonged.

Description

technical field [0001] The invention relates to the technical field of adjusting differential starting torque, in particular to an adjusting device for differential cone bearings. Background technique [0002] The starting torque of the differential cone bearing of the transmission refers to that after the transmission is assembled, use a special tool to insert the internal splines of the side gears at both ends of the differential to make the side gears at both ends into one, and then use a torque meter to measure the transmission. The torque at which the differential assembly starts to rotate. [0003] The starting torque is directly related to the appropriate axial preload of the differential cone bearing. If the axial preload of the cone bearing is large, the differential’s starting torque will be large, which will lead to accelerated wear of the cone bearing and transmission failure. The transmission efficiency is reduced; the axial preload of the tapered bearing is sm...

Problems solved by technology

[0007] The purpose of the present invention is to provide an adjusting device for differential cone bearings, which solves the need for more equipment for the selection of the existing adjusting shims for adjusting the starting torque, and the adjusting shims can only be adjusted once, and it is not easy to adjust the bearing after the bearing is worn out. Adjustment leading to technical problems of tapered bearing premature failure
