The cooperation between the thrust bearing and the shaft is usually a transitional cooperation; the cooperation between the race and the bearing housing hole is usually the cooperation of the gap, and the middle shaft of the two-way thrust bearing should be fixed on the shaft; to prevent the transformation of the thrust bearing relative to the shaft; Under normal conditions, the shaft rotation is mostly; therefore, the cooperation between the inner ring and the shaft is a win-win cooperation; the cooperation between the outer ring of the bearing and the bearing chamber is the cooperation of the gap.
When installing the thrust bearing; check the straightness of the axial line of the shaft ring and the shaft. The method is to fix the dial gauge to the end face of the casing; make the contact of the watch top on the bearing shaft raceway to change the bearing; Pointer; if the pointer is yaw; clarify that the middle line of the shaft and the shaft is not straight. When the box hole is deep; it can also be checked with the extended dial gauge. When the thrust bearing device is correct; the seat can actively get used to the roll of the roll. Ensure that the rolling body is located in the upper and lower ring raceways. If it is reversed; not only the bearing operation is not normal; and the cooperation faces will be severely worn. Because the shaft ring and the seat ring are not very significant; the device should be taken care of; Do not make mistakes. In addition, there should be a gap of 0. 20.5 mm between the seat of the thrust bearing and the hole of the bearing housing; to compensate for the inaccurate formation of the parts and the inaccurate formation of the device; In the middle offset; this gap can ensure its active adjustment; prevent collisions; make it work properly; otherwise; will cause severe damage to the bearing.
