Thrust bearing must carry on the inspection after installation, the installation when thrust bearing must first inspection shaft and shaft centerline of verticality.
Test method is: in the end will dial gauge box shell, make the table touch the top of the head on the bearing axis ring raceway on bearing, and then observe the dial gauge pointer, if shaft ring and shaft centerline is not vertical deflection of the pointer.
Dial gauge pointer is longer, if the tank shell hole deep, also can choose to use extended test dial gauge head.
Seat can automatically adapt to roller rolling, to ensure that the rolling body located at the top and bottom ring raceway, then thrust bearing installed correctly.
If the wrong thrust bearing, if appear such circumstance.
Bearing is not working, and bearing the mating surface will badly worn.
The difference between the shaft ring and seat is not very obvious, so should be extra careful in assembly.
And, when installing thrust bearing seat and the bearing hole there should also be between 0.
2 -
0.
5 mm gap, the gap to compensate parts processing, installation error caused by inaccurate, if unexpected, when the bearing ring during operation center offset, the gap will produce very big effect, can ensure that the automatic adjustment, the avoidance of friction, make bearing can run properly.
If there is no this gap will cause bearing severe damage.
The bearing damage cannot be used.
