The boss in the shell 5, the bushing 6 and the end cover 3 are matched with each other, so that the axial direction 8 positioning of the bearing is realized.
The tapping component comprises a locking screw 1, an upper positioner 2, a hollow shaft 7, a screw tap 9 and a lower positioner 10.
The hollow shaft 7 is provided with a stepped outer surface cylinder, a shaft shoulder on the outer circle and a circular through hole inside, the top is provided with a boss with a threaded hole along the radial direction, and the bottom is provided with a section of internal thread. Go up 2 insides of locator and be circular through-hole, this hole diameter and screw tap 9 external diameter unanimous, go up 2 outward appearance wholly and be ladder cylindricly, the less one end of diameter inserts the inside of hollow shaft 7 (and hollow shaft 7 hole be clearance fit), the great one end of diameter is processed a plane to along radial design has a circular through-hole, this through-hole and hollow shaft 7 upper end screw thread through-hole are adjusted well, and keep same axis. The lower locator 10 is internally provided with a circular through hole, the shape of the lower locator is similar to a bolt, and the lower locator 10 is screwed on the thread at the lower end of the hollow shaft 7. The upper positioner 2 is arranged at the upper end of the hollow shaft 7 (in clearance fit with the hollow shaft), the lower positioner 10 is arranged at the lower end of the hollow shaft 7, the screw tap 9 penetrates through the upper positioner 2 and the lower positioner 10 (the screw tap 9 is in clearance fit with the upper/lower positioners), and the locking screw 1 penetrates through a threaded hole in the upper end of the hollow shaft 7 and a circular hole in the upper positioner 2 and is in contact with the screw tap 9 to lock the screw tap 9, so that the screw tap 9 and the hollow shaft 7 synchronously rotate.
