Description

Technical Field

[0001] The utility model relates to the technical field of bearing rings, in particular to a corrosion-resistant bearing ring. 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. Under a certain load, the number of revolutions or hours that a bearing experiences before pitting occurs is called the bearing life. In order to compare the bearing's anti-pitting capacity, the rated life of the bearing is specified to be one million revolutions. The bearing ring is an annular part of a radial rolling bearing with one or more raceways.

[0003] China's publicly authorized invention: CN220726879U discloses a corrosion-resistant and wear-resistant bearing ring, including an inner ring, a first outer ring, a second outer ring, a retaining frame and a ball. The outer side of the inner ring is provided with a first outer ring and a second outer ring, and the first outer ring and the second outer ring are fixedly connected by fixing bolts. A retaining frame is provided between the inner ring and the first outer ring and the second outer ring. A limit rod is fixedly provided on the inner side surface of the lower end of the pulling rod, and a guide groove is provided on the outer side surface of the upper end of the pulling rod. The corrosion-resistant and wear-resistant bearing ring, by injecting a sufficient amount of lubricating oil into the liquid storage chamber, enables the bearing ring composed of the first outer ring and the second outer ring to continuously replenish lubricating oil at the retaining frame during the rotation of the bearing, and utilizes the rotation of the retaining frame and the inner ring to allow the lubricating oil to splash onto the inner side surfaces of the first outer ring and the second outer ring, thereby ensuring that the inner ring, the first outer ring and the second outer ring can maintain a good lubrication state and reduce the corrosion rate;

[0004] However, there are still some problems with the device. In actual use, due to the gap between the inner ring and the outer ring, large particles of dust can easily enter the raceway through these gaps, rubbing against the ball and raceway surfaces, resulting in severe wear of the ball and raceway. Therefore, we proposed a corrosion-resistant bearing ring to solve the above problem. Utility Model Content
