Description

Novel bearing retainer Technical Field The utility model belongs to the technical field of bearing retainers, and relates to a novel bearing retainer. Background The defects of the existing bearing retainer in the aspect of bearing stress uniform distribution are mainly characterized in that the friction difference between rolling bodies and the deformation problem of the retainer cannot be completely eliminated. Because the cage is not always capable of ensuring that the friction force of each rolling body contacted with the cage is completely consistent in design, uneven stress can occur among the rolling bodies in the running process of the bearing. In addition, the retainer may deform during high-speed rotation or heavy load bearing, further exacerbating uneven stress. Conventional coping methods include optimizing the design of the cage, such as by using symmetrical structures and reducing friction between the rolling bodies and the cage by lubrication. However, these methods have drawbacks in that the optimization of design and improvement of machining accuracy are often accompanied by an increase in cost, while lubrication can reduce friction, lubrication effects may be greatly impaired at high temperature, high rotation speed or in severe environments, and periodic maintenance and replacement are required, increasing maintenance costs and complexity, and thus, a new bearing cage is now demanded to solve the above problems.
