Installing a thrust bearing, shaft circle shall be checked and verticality of shaft centerline.
Method is to fix the dial gauge box shell end face, make the table touch the top of the head of the ring raceway on bearing axle bearing, and observe the dial gauge pointer, if the pointer deflection, axial circle and not vertical shaft centerline.
Box shell hole deep, also can use extended dial gauge head test.
Thrust bearing installed correctly, the seat can automatically adapt to roller rolling, to ensure that the rolling elements located at the top and bottom ring raceway.
If installed backwards, bearing not only don't work properly, and the matching surface will badly worn.
Due to axial ring and seat and the difference is not obvious, the assembly should be extra careful, do not make a mistake.
In addition, the seat of thrust bearing and the bearing holes should also be left between 0.
2 -
0.
5 mm clearance to compensate parts processing, installation error caused by inaccurate, when the bearing ring during operation center offset, the clearance can be adjusted to ensure the automatic, the avoidance of friction, make its normal operation.
Otherwise, will cause bearing severe damage.
