The cooperation between thrust bearing and shaft is the current research, investigation and analysis; it can be said that only one cooperation between the two is for the transition cooperation; the cooperation between the seat and the bearing housing hole is usually the cooperation of the gap, how can the thrust bearing be installed; Check the straightness of the shaft ring and the middle line of the shaft. The method is to fix the dial gauge to the end face of the box; make the contact of the watch top on the bearing shaft raceway and change the bearing; while investigating the dial indicator; if the pointer is yaw ; clarify that the collar and the middle of the shaft are not straight.
Because the shaft ring and the seat ring and the difference are not very significant; the device should be taken care of; do not make mistakes. The middle shaft ring of the two-way thrust bearing should be fixed on the shaft; to prevent the transformation relative to the shaft. Under normal conditions, the rotation of the shaft 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. If it is reversed; not only the bearing operation is not normal; Severe wear and tear.
In addition, there should be a gap of 0. 20.5 mm between the seat ring of the thrust bearing and the bearing housing hole; to compensate for the error in the machining of the parts and the inaccurate formation of the device; when the bearing ring is offset in the middle during operation; This gap can ensure its active adjustment; prevent collisions; make it work properly; otherwise; it will lead to severe damage to the bearings. It can be said that these are the time-consuming needs of the device.
