high speed bearing Surface roughness analysis

Surface roughness analysis effect of crossed roller bearing properties
Effect of surface roughness on the performance of cross roller bearings parts is mainly manifested in the following aspects:
1, the surface roughness affect the high speed bearing wear resistance of parts. The surface is rough, with the effective contact area between the surface pressure is smaller, faster, and wear.
2, the surface Double Row Ball Slewing Bearing roughness effects of cross roller bearing ring with the properties of stability. The clearance fit, the surface of the more
Rough, more easy to wear, so the work process of intermediate gap gradually
Increased; the interference fit, the assembly will micro convex peak crowded flat, reduces the effective interference, reduce the
The strength of the bond.
3, the surface roughness of fatigue strength of Thin section bearings bearing parts. There is a big trough surface roughness of parts, they are like sharp
Angular notch and crack, the stress concentration is very sensitive,
Thus affecting the fatigue strength of parts.
