First spring is connected with fixture block, and the side wall of the annular mounting groove is provided with the annular slot of fixture block matching, in the bearing inner race
The threaded rod laterally set is rotatably connected to by tumbler, and threaded rod is set through bearing inner race, the side of the threaded rod
Wall is arranged with matched nut, and the side wall of the nut is provided with push rod, and push rod is set through the side wall of annular slot, institute
The side wall for stating annular slot is additionally provided with two chutes, and two chutes are located at the both sides of fixture block respectively, and two chutes are logical
Sliding block is crossed to be slidably connected with fixture block.
Preferably, the surface of the bearing outer ring is coated with anticorrosion material.
Preferably, the bottom of the annular mounting groove is provided with oil filler point.
Preferably, the opening of the annular mounting groove is arranged with dust cover.
Preferably, it is enclosed with rubber protecting jacket on the threaded rod.
The present invention is simple in construction, and easy to operate, bearing outer ring and bearing inner race can be carried out changing, because both are cards
It is buckled together, so installation, dismounting are all more convenient, during dismounting, rotates threaded rod, the nut on threaded rod is because there is push rod
Limitation, so threaded rod drive nut movement, nut drive push rod by annular slot fixture block ejection goes, fixture block retraction it is recessed
In groove, mounting blocks are pulled out annular mounting groove, bearing outer ring and bearing inner race separation by second spring, and both, which are disassembled, separates, peace
During dress, threaded rod is rotated backward, threaded rod drives nut reverse movement, and nut is with push rod return-to-home position, then by fixture block
In pinch groove, mounting blocks are fitted into annular mounting groove, the first spring snaps into fixture block in annular slot, and bearing outer ring is pacified
On bearing inner race, this is simple and practical, easy to operation.
