Positioning of bearing outer ring

When the bearing outer ring is installed in the shell hole, the inner side of the shell hole generally has a fixed bearing position for the shoulder, and the other side is positioned with an end cover, a thread ring and a hole with an elastic stop ring.

(1) End cover positioning

End cover positioning is used for all types of centripetal bearings and angular contact bearings in the case of high bearing speed and large axial load. The end cover uses screws to locate and press the outer ring of the bearing, and the end cover can also be made into a labyrinth sealing device.

(2) Thread ring positioning

When the bearing speed is high and the axial load is large, and the end cover is not suitable for positioning, the threaded ring can be used to locate the centripetal bearing and thrust bearing, and the axial clearance of the bearing can be adjusted at this time.

(3) Positioning of elastic baffle ring

This positioning method occupies a small axial position, convenient installation and disassembly, simple manufacturing, suitable for bearing small axial load. An adjustment ring is added between the bearing and the spring to facilitate the adjustment of the axial position.

(4) Deep groove ball bearings with stop grooves on the bearing outer ring can be located by stop rings.

This type is used when the stop shoulder cannot be processed in the shell hole due to the limitation of conditions, or the parts must be reduced in outline size.
