The cooperation of the shaft ring and the shaft of the thrust bearing is usually a transitional cooperation; the cooperation between the race and the bearing housing hole is usually the cooperation of the gap; therefore, the bearing is easier to install; the middle shaft of the two-way thrust bearing should be fixed on the shaft; Relative to the axis transition.
When the thrust bearing device is equipped with a thrust bearing; the straightness of the axial line of the shaft ring and the shaft should be checked. The method is to fix the dial gauge to the end face of the casing; and to make the contact of the table top change the bearing on the bearing raceway; Dial indicator; if the pointer is yaw; clarify that the center line of the shaft and the shaft is not straight. When the box hole is deep; it can also be checked with a long dial indicator.
When the thrust bearing device is correct; its seat can actively get used to rolling of the rolling body; 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 and the difference 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 bearing housing hole; Errors in parts processing and device inaccuracies; when the bearing ring is offset in the middle during operation; this gap can ensure its active adjustment; prevent collisions; make it work normally; otherwise; it will cause severe damage to the bearing.
