详细说明
A cage (bearing cage, also known as bearing cage) refers to a bearing part that partially encloses all or part of a rolling body and moves with it to isolate the rolling body, usually guiding the rolling body and keeping it in the bearing.
When the rolling bearing is working, especially when the load is complex and the speed is rotating, the cage has to bear great centrifugal force, impact and vibration, and there is great sliding friction between the cage and the rolling body, and a lot of heat is generated.The combined effect of force and heat can result in cage failure, and in severe cases, cage burns and breakage.Therefore, the cage material is required to have good thermal conductivity, good wear resistance, small friction coefficient, a small density, a certain strength and toughness with good elasticity and stiffness.The coefficient of expansion similar to that of the rolling body.And good processing technology performance.In addition, the cage is also subject to chemical media, such as lubricants, lubricant additives, organic solvents and coolants.
