Surface roughness analysis effect of crossed roller bearing properties
Effect of surface flanged ball bearing roughness on the performance of cross roller bearings parts is mainly manifested in the following aspects:
1, the surface roughness affect the 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 roughness effects of cross roller bearing ring with the properties of stability. The clearance fit, the surface of the Full complement cylindrical roller bearings 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 bearing parts. There is a big trough surface roughness of parts, they are like sharp
Angular notch and slewing bearing crack, the stress concentration is very sensitive,
