LYHY deck crane bearing,wheel bearing,wind power bearing

Bearing is the other parts on the shaft will produce relative motion, used to reduce friction coefficient during power transmission and keep the machine shaft center fixed position, its main function is to support the rotary body, in order to reduce the equipment in the transmission process of mechanical load friction coefficient. According to the motion of the frictional properties of different components, bearings can be divided into two types of rolling bearings and sliding bearings.

deck crane bearing the main reason for the formation of the spiral line

1 grinding wheel dressing is bad, not chamfered corner, without the use of cooling liquid dressing;

Track 2 table guide lubrication oil too much, cause the work station floating;

3 machine tool accuracy is not good;

4 the grinding deck crane bearing pressure and so.

(two) with the formation of the spiral line

1.V guide not good rigidity, the grinding wheel edge offset, just contact with the work surface;

2 dressing noisy round table reversing speed is not stable, the precision is not high, the grinding wheel is a slightly less edge trimming;

The 3 workpiece itself poor rigidity;

4 wheel is broken too peeled off the sand and angular contact bearing grinding of iron deposition in the grinding wheel on the surface, this should be trimmed grinding wheel with cooling water rinse or wash clean;

5 wheel dressing is not good, local projection etc..

Analysis of causes of bearing grinding traces generated.
