Description

Technical Field

[0001] The utility model relates to the technical field of waste recycling of bearing retainers, in particular to a bearing retainer processing waste recycling device. Background Art

[0002] Commonly used cages are divided into metal cages and non-metallic cages according to the type of material. Generally, metal cages are more common. When the bearing is working, especially when the load is complex and the bearing rotates at high speed, the cage must withstand large centrifugal forces, impacts and vibrations. There is a large sliding friction between the cage and the rolling element, and a large amount of heat is generated. The combined effect of force and heat will cause the cage to fail. In severe cases, it will cause the cage to burn and break. Therefore, the bearing cage needs to be recycled after being discarded.

[0003] Application No. 202122198710.8 discloses a waste material processing device for bearing retainer processing, including a crushing box, two rollers are rotatably installed on the inner walls of both sides of the crushing box, and the outer walls of the two rollers are fixedly connected with a plurality of crushing blades.
