Description

Technical Field

[0001] The utility model relates to the technical field of retaining frames, in particular to a retaining frame for a deep groove ball bearing. Background Art

[0002] Cage (i.e. bearing cage, also known as bearing retainer) refers to a bearing part that partially wraps all or part of the rolling elements and moves with them, used to isolate the rolling elements, and usually guides the rolling elements and keeps them in the bearing. When the rolling bearing is working, especially when the load is complex and the rotation is high-speed, the cage must withstand great centrifugal force, impact and vibration, there is a large sliding friction between the cage and the rolling elements, and a large amount of heat is generated. The combined effect of force and heat will lead to cage failure, and in severe cases, it will cause the cage to burn and break. Therefore, the cage material is required to have good thermal conductivity, good wear resistance, low friction coefficient, low density, a certain strength and toughness combination, good elasticity and stiffness, expansion coefficient similar to the rolling elements, and good processing performance. In addition, the cage is also affected by chemical media, such as lubricants, lubricant additives, organic solvents and coolants. Commonly used cages are mainly divided into metal cages and non-metallic cages according to the type of material. There are also composite cages. Bearing cages for special purposes should also meet the requirements of special working conditions, such as high temperature resistance, corrosion resistance, self-lubrication (for use in vacuum) or non-magnetic, etc.
