Description

Technical Field

[0001] The present application relates to the technical field of bearing gaskets, and in particular to a wear-resistant bearing gasket. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. In the assembly of automotive parts, a large number of bearings are often required. The gap between the half-shaft and the bearing in the mechanical equipment will cause axial deviation and affect normal operation. Therefore, the purpose of adding gaskets to the bearings is to fill these gaps and keep the bearings running normally.

[0003] Patent announcement number CN218510123U discloses an automobile gearbox bearing adjustment gasket. The anti-rust function is achieved by setting an epoxy anti-rust paint layer, an inorganic zinc silicate primer layer and an epoxy iron red paint layer to avoid corrosion caused by environmental factors. The wear-resistant function is achieved by setting a titanium nitride coating, a phenolic resin coating layer and a fluorocarbon coating layer to avoid damage to the adjustment gasket body due to excessive friction, greatly improving the service life of the adjustment gasket body, and solving the problem that the existing gasket does not have the wear-resistant function. When in use, the friction between the gasket and the gear is large, which easily causes damage to the gasket, greatly reducing the service life of the gasket.

[0004] Although the above device solves the problem that the existing gasket does not have the wear-resistant function, it is similar to the existing gasket structure and is an integrated design, which results in the aperture and overall size of the gasket being relatively fixed. Once the gasket is damaged somewhere, the entire gasket needs to be replaced, which is correspondingly not conducive to controlling the cost of use. Utility Model Content
