Problems solved by technology

[0005] After the inner edge of the shaft sleeve and the end face of the side gear is chamfered to form a bevel, the sealing ring is arranged between the bevel and the root of the journal of the side gear, which not only solves the sealing problem there, but also does not It affects the firmness of the connection between the bushing and the side gear, and the sealing ring will not be worn due to the rotation of the side gear during work, which improves the service life of the sealing ring and greatly improves the connection between the bushing and the side gear. The reliability of the seal

Embodiment Construction

[0008] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0009] Such as figure 1 , figure 2 As shown, in the sealing structure between the rear axle sleeve and the differential side gear provided by the present invention, the journal of the side gear 2 is located in the shaft sleeve 1, and the shaft sleeve 1 is axially connected to the end of the side gear 2 The chamfering of the inner edge of the face-to-face contact end forms a bevel 3 , and a sealing ring 5 is arranged between the bevel 3 and the journal root 4 of the side gear 2 . After the inner edge of the contact end of the shaft sleeve 1 and the side gear 2 is chamfered to form a bevel 3, the sealing ring 5 is arranged between the bevel 3 and the journal root of the side gear 2, which solves the problem The sealing problem does not affect the firmness of the connection between the shaft sleeve 1 and the side gear 2, and the sealing ring 5 will not be wor...

Abstract

A sealing structure between a rear axle sleeve and a differential axle gear, wherein the journal of the axle gear (2) is located inside the axle sleeve (1), and the axle sleeve (1) is axially connected to the axle gear ( 2) The chamfering of the inner edge of the contact end of the end face forms a bevel (3), and a sealing ring (5) is arranged between the bevel (3) and the arc-shaped transition surface of the shaft journal root (4) of the side shaft gear (2). The invention makes the seal between the shaft sleeve and the half shaft gear more reliable and has a longer service life without affecting the fastness of the connection between the shaft sleeve and the half shaft gear.

Description

technical field [0001] The invention relates to the improved design of the sealing structure between the upper half shaft sleeve of the rear axle and the half shaft gear of the differential device. Background technique [0002] There is usually no seal between the axle sleeve of the existing motorcycle rear axle and the differential axle gear in the axial direction. The radial gap between them seeps out, so that the inside of the differential is not fully lubricated. In order to prevent oil leakage, some people add a sealing ring between the rear axle sleeve of the motorcycle and the end face of the differential axle gear. The sealing ring is pressed on the end face of the axle gear by the axial force of the axle sleeve. Although the problem of oil sealing here has been solved to a certain extent, due to the existence of sealing rings, the rear axle bushing is in a non-rigid connection in the axial direction with the differential axle gear, and it is easy to appear between ...
