Axis under normal circumstances is mostly the case, the inner ring and shaft had to win to tie in with the bearing outer ring and bearing for the clearance fit with the room. Install thrust bearing, it should ring and check the shaft centerline of the vertical axis. Methods are: the dial gauge fixed on the end of shell, so that the head touch the table in the upper bearing shaft rotation bearing ring raceway, while observing dial gauge pointer, if the pointer deflection, indicating that ring and the shaft axis is not perpendicular to the centerline. Tank shell hole deeper, longer in the dial gauge can also be used the first test. Thrust bearing is installed correctly: the seat that automatically adapts to the rolling rolling, rolling to ensure that rings at the upper and lower raceway. If installed backwards, not only the bearing is not working properly, and each with the surface would be subjected to severe wear. Circle and the shaft seat and not very obvious difference, the assembly should be careful not to mistake. In addition, the thrust bearing seat and bearing holes should be left between the 0.2-0.5mm gap, to compensate for part processing, the error caused by inaccurate installation, when running in the bearing ring center offset, this gap to ensure its automatic adjustment, avoid touching the friction, so that normal operation. Otherwise, it will cause severe damage bearings. How to install the thrust bearing and install the thrust bearing installed after the test, you should check the shaft ring and the center line of vertical axis. The dial gauge is fixed on the end of shell, so that the head table in the bearing axis touch ring raceway bearings rotate on top, while observing dial gauge pointer, if the pointer deflection, indicating that ring and the shaft axis is not perpendicular to the centerline. Tank shell hole deeper, longer in the dial gauge can also be used the first test.
