What is the disassembly method of the miniature spherical bearing?

- Mar 04, 2019-

The micro spherical bearing is used to fix the inner ring of the bearing and the shaft through an eccentric sleeve, and the hexagon socket screw on the eccentric sleeve is used for fastening. When disassembling such a bearing, first loosen the locking screw on the eccentric sleeve of the bearing with an Allen key, then insert the small iron rod into the counterbore on the eccentric sleeve of the top cover, and loosen the eccentric sleeve against the rotation direction of the shaft. .

 

Loosen the bolts that secure the bearing housing. Remove the bearing from the shaft together with the housing. Note before removing the bearing housing at one end of the shaft. The bearing block bolts at the other end of the shaft should be loosened to prevent the bearings at both ends from being damaged by each other. When installing the miniature spherical bearing, the fixing pin of the bearing outer casing must be unplugged, and the surface of the journal surface should be smoothed and cleaned, and the oil is rust-proof and lubricated at the journal.

 

Apply lubricant to the bearing seat and bearing mating surface, and install the bearing into the bearing housing. Then the assembled bearing is placed on the shaft together with the bearing housing. Push to the desired location for installation. The bolts of the fixed bearing housing should not be tightened first, so that the bearing housing can rotate in the bearing housing. Also install the other end bearing and seat on the same shaft, turn the shaft a few turns, and let the bearing itself automatically find the position. Then fasten the bearing block bolts.

 

Finally, the eccentric bushing is placed on the eccentric step of the bearing inner sleeve, and the hand is screwed in the direction of the shaft. Then insert or hold the small iron rod against the counterbore on the eccentric sleeve. Tap the small iron rod with the hammer in the direction of the shaft to make the eccentric sleeve securely fast, and finally lock the hexagon socket screw on the eccentric sleeve.
