Basic idea of bearing cage design
1 The design of the main parameters is determined according to the service conditions of the bearing in the main engine and the requirements of the guide clearance (which can be divided into inner diameter guide, outer diameter guide or rolling fatigue experiment body guide)
2. According to the load, speed, temperature rise, lubrication, corrosion resistance and other requirements of the bearing parts, the materials and processing technology shall be reasonably selected
3. According to the working conditions of the bearing, there are special performance requirements such as impact resistance, fatigue resistance, high strength, wear resistance, corrosion resistance, self lubrication, etc. for the cage with excellent heat resistance and environmental resistance, the surface strengthening, surface chemical treatment, surface copper plating, silver plating, gold plating and other processes in recent years should be carried out to improve the effective service performance. The design and calculation of the main parameters of all kinds of cages can touch the industries of new energy vehicles, high-end equipment manufacturing, information technology, energy conservation and environmental protection, biomedicine, etc., and can be designed and calculated with reference to the relevant product design methods. The general principle is to ensure that the bearing cage correctly guides the rolling element without dropping or clamping the rolling element, and that the pocket clearance is appropriate, the rotation is flexible, and there is no blockage.
