Embodiment Construction

[0018] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0019] The invention discloses a gasket structure with enhanced wear resistance, which comprises a gasket 1 body, and at least one oil passage groove 2 penetrating through the working end surface is arranged on one end surface or both sides of the gasket 1 .

[0020] Generally, the gasket 1 is set in the axial gap between the gear and the gear or between the bearing assembly and the bearing surface. When the original gasket structure is in working condition, there is a certain amount of lubricating oil around the gasket 1. , but the gasket 1 is in contact with the gear or bearing and the bearing surface and generates friction on one or both sides of the end surface. Due to the effect of pressure, it is closely attached to the gear, so the lubricating oil cannot enter the working end surface of the gasket 1.

[0021] In the present invention, th...

Abstract

The invention discloses a gasket structure capable of enhancing wear resistance. The gasket structure comprises a gasket body. At least one oil through groove which penetrates through the end face is formed in the working end face on one side or the working end faces on the two sides of the gasket body. According to the gasket structure capable of enhancing the wear resistance, due to the fact that the at least one oil through groove which penetrates through the working end face is formed in the working end face of the gasket body, the gasket structure is changed, then, lubricating oil around the gasket body enters the oil through groove, when the gasket body is rotated, the oil through groove rotates along with the gasket body, the lubricating oil in the oil through groove can make contact with the working end face of the gasket body, lubricating oil films are formed on the contact surface, therefore, the gasket body has the self-lubricating effect, and the wear extent of the gasket body is reduced.

Description

technical field [0001] The invention belongs to the technical field of automobiles, relates to the structure of automobile spare parts, in particular to a gasket structure. Background technique [0002] The friction mode inside the transmission is divided into rolling friction and sliding friction. Rolling friction is mainly carried out by bearings, while sliding friction is mainly on the axial contact surface. It is difficult to arrange bearings in such places, or the increased cost cannot keep up with the effect produced. During the sliding friction process, the friction surface will be worn, and the wear of the axial contact surface will inevitably lead to an increase in the axial clearance, which will lead to an increase in the amount of axial movement, which is not conducive to bearing or gear transmission, and even causes transmission failure. At present, in view of the contact and sliding friction between the gear and the gear end face, generally a gasket is directly ...
