When the device thrust SKF 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; the top of the contact of the watch is transformed into the SKF bearing on the raceway of the SKF imported bearing shaft ring; Investigate the dial indicator; if the pointer is yaw; clarify that the collar and the middle of the shaft are not straight. When the box hole is deep; you can also use the extended dial gauge to check. Inspection is very important; this is no matter mechanical novice Still the demand for mechanical internals is concerned. The quality of SKF bearings is still very good; but the demand is also tested; if the test is not good, it is basically impossible. We want to use SKF bearings is really not a A simple job; the demand has a lot of bearing professional knowledge to be able.
When the thrust SKF 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 SKF bearing operation is not normal; and the cooperation faces will be severely worn. Because the shaft The circle and the seat are not very noticeable; 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 SKF bearing and the hole of the SKF bearing seat. Used to compensate for errors in parts processing and inaccurate device formation; when the SKF bearing ring is offset in the middle of work; this gap can ensure its active adjustment; prevent collision conflict; make it work normally; otherwise; will lead to SKF bearing Severe damage.
