SKF bearing vibration model and the difference between ordinary - bearing knowledge

Vibration type of SKF bearing ring and the shaft or hole, need certain transition fit or interference fit, size of interference to SKF bearing work under load, the SKF bearing ring at the hole with the shaft or does not produce 'creeping' phenomenon on the surface for the principle. Type a, said first SKF bearing vibration, SKF bearing vibration model of inside and outside the ring and roller adopts vacuum degassed bearing steel, fatigue resistance performance is good. And keep the frame adopts aluminum iron manganese bronze material, high strength, good elasticity, wear-resisting performance is better. Second, look at the normal SKF bearing, SKF bearing type inside and outside the circle and using the ordinary bearing steel roller. And keep using zinc brass material, low strength, poor elasticity. So, how to choose to be with SKF bearing vibration type or SKF bearing type? Fixed load, the following three points for reference: 1, the characteristics of fixed load is a synthesis of radial load vector and the relative static ring. 2 rotating load, rotating load characteristic is synthesized radial load vector rotate relative to the ring. 3 oscillating load and variable load, oscillating load refers to the rotating load is much lower than the fixed load and synthetic load. Oscillating load refers to some ring load may sometimes is rotating load, sometimes is a fixed load, sometimes is oscillating load.
