Bearings with taper inner bore are installed on the taper shaft
Deep groove ball bearings with a stop groove on the outer ring of the bearing can be positioned with a stop ring. Positioning of the bearing inner ring When installing the bearing inner ring on the shaft, the bearing is generally fixed by the shoulder on one side, and the other side is fixed with a nut, a stop washer or a spring ring. For positioning with more than one screw, use a stop washer or iron wire to tighten to prevent loosening. This type is used when the stop shoulder cannot be processed in the housing hole due to conditions, or the part must be reduced in outline size.
It is suitable for places with small axial loads.. Use the nut and the stop washer to locate, put the inner key teeth of the stop washer into the keyway of the shaft, and then bend one of the teeth on the outer ring into the notch of the nut. 2.1. It is necessary to make the axial load check against the shaft and the bearing. The end cover uses screws to locate and compress the outer ring of the bearing, and the end cover can also be made into a labyrinth sealing device. Otherwise, even if the nut is tightened, the installation position of the bearing and the normal working condition of the bearing will be damaged, and the rotation accuracy and service life of the bearing will be reduced. (6) Special positioning In some special circumstances, when the shoulder and fillet dimensions of the shaft cannot be determined according to the installation dimensions listed in this catalog, transition gaskets can be used as axial support.
Especially when the fit between the inner bore of the bearing and the shaft is a loose fit, strict control is required. An adjustment ring is added between the bearing and the spring to facilitate adjustment of the axial position. The dimensions of the contact part between the shaft shoulder and the axial fixed parts and the inner ring of the bearing can be determined according to the installation dimensions of the various bearings listed in the bearing size table.

Adapter sleeve positioning The spherical roller bearing, which has a low bearing speed and bears smooth radial load and low axial load, can be installed on the optical axis with the aid of a tapered adapter sleeve. In this case, the combined threaded ring can be clamped into the groove of the shaft, and then the nut can be used to locate the bearing. (1) Nut positioning When the bearing speed is high 625 ball bearing and bearing a large axial load, the end face of the nut and the inner ring of the bearing should be perpendicular to the rotation center line of the shaft. Bearings with taper inner bore are installed on the taper shaft. At this time, it can be used to adjust the axial clearance of the bearing
