Description

Technical Field

[0001] The utility model relates to the technical field of automobile bearings, in particular to a wear-resistant automobile bearing. Background Art

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Life: The number of revolutions or hours that a bearing experiences before pitting occurs under a certain load is called the bearing life. The life of a rolling bearing is defined by the number of revolutions: within this life, the bearing should not experience initial fatigue damage (peeling or defect) on any of its bearing rings or rolling elements.

[0003] At present, when the existing automobile bearings are in use, the long-term rotation of the balls on the raceways will cause the raceways to wear, resulting in deflection of the rolling balls, which will affect the service life of the bearings. In this regard, we have proposed a wear-resistant automobile bearing to solve the above-mentioned problems. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model improves the wear resistance of the raceway of the automobile bearing by installing a detachable reinforcement ring made of high manganese steel on the bearing ring. At the same time, after the automobile bearing is used for a long time and the raceway is worn, only the reinforcement ring needs to be replaced without replacing the entire bearing ring. This improves the wear resistance of the automobile bearing and reduces the maintenance cost of the automobile bearing, and has strong practicality.

[0013] 2. The utility model can provide good protection for the raceway and the ball by setting a cover plate between the two bearing rings of the automobile bearing, thereby preventing external dust and impurities from entering the raceway and the ball and causing bearing wear. The heat dissipation port opened on the cover plate can facilitate the heat dissipation of the ball and the reinforcing ring, and the dustproof net set on the heat dissipation port can prevent external dust and impurities from entering the inner cavity of the automobile bearing through the heat dissipation port.
