slewing ring bearings 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 wear resistance of parts. The surface is rough, with the effective contact area between the surface pressure is smaller, faster, slewing ring bearings‍ and wear.

2, the surface 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 crossed roller bearing slewing rings‍ of 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.                                                                                                                            ‍
