Description

Technical Field

[0001] The utility model relates to the technical field of bearing ring production, and more specifically to a bearing ring with a self-lubricating function. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies and reduce the friction coefficient during their movement. Bearing rings are an important component of bearings. However, during use, commonly used bearing rings facilitate the contact between lubricating oil and rolling elements, but they do not have the function of storing oil and self-lubricating the rolling elements. When users are unable to apply lubricating oil frequently, the bearings will wear faster and their service life will be shortened.

[0003] For example, the bearing ring and the bearing having the bearing ring disclosed in Publication No. CN206555292U, the bearing ring includes a raceway and a shoulder located on one side or both sides of the raceway in the axial direction of the bearing ring, and is characterized in that a plurality of oil guide grooves are arranged on the shoulder of the bearing ring.

[0004] It can be seen from the above-mentioned public scheme that a plurality of oil guide grooves are arranged on the surface of the bearing ring to facilitate the contact between the lubricating oil and the internal rolling elements. However, the bearing ring cannot store the lubricating oil and requires the user to apply the lubricating oil frequently to achieve lubrication. It does not have the function of self-lubrication. Forgetting to apply the lubricating oil for a long time may cause accelerated wear of the bearing ring and the rolling elements, thereby shortening the service life of the bearing.

The bearing ring can come into contact with the lubricating oil during the rolling process of the rolling body, has a self-lubricating function, and greatly extends the service life of the bearing. In addition, through the sealing sleeve, not only can the oil storage groove be sealed, which is convenient for the setting of the oil storage groove, but also the supporting strength of the outer ring of the bearing can be increased, thereby ensuring the supporting stability of the outer ring of the bearing.
