Specific embodiment
Specific introduction is done to the utility model with reference to the accompanying drawings and examples.
As shown in Figs 1-4: the present embodiment is a kind of tricot machine lever jack flange bearing, including self-aligning bearing, aligning axis
The steel ball 1 held is rolled by retainer 2 to be arranged between bearing inner race 4 and bearing outer ring 5, and the bearing inner race 4 of self-aligning bearing is
Taper sheath, is interspersed with tightening tapered sleeve 3 in the bearing inner race 4 of self-aligning bearing, and self-aligning bearing is socketed in guide by tightening tapered sleeve 3
On bar, the outer circumference surface of tightening tapered sleeve 3 includes cylinder face and taper face, the cone of bearing inner race 4 taper sheath and tightening tapered sleeve 3
The cooperation of shape face, the cylindrical surface portion of tightening tapered sleeve 3 is located at 4 outside of bearing inner race of self-aligning bearing, in 3 outer circumference surface of tightening tapered sleeve
Cylinder face be formed with screw thread and be threaded with nut 7, by rotating nuts 7 pull tightening tapered sleeve 3, tightening tapered sleeve 3
Taper face and the cooperation of 4 taper sheath of bearing inner race generate deformation, and then lever jack and bearing inner race 4 are fastenedly connected.
In the present embodiment, the outside cladding of the bearing outer ring 5 of self-aligning bearing is provided with injection molded flange structure 6, is being molded
It is provided with mounting hole on flange arrangement 6, is used for integral installation in bearing block.
In the present embodiment, nut 7 is the nut of locking notch, and lock banking stop 8 is arranged between nut 7 and bearing inner race 4,
Multiple claws are distributed on lock banking stop 8, after nut 7 is tightened, one of claw is embedded in inside the locking notch on nut 7, lock
Firmly nut 7 prevent nut 7 from loosening.
The present embodiment on nut 7 in practical application, can also be formed with multiple locking notch, and the lock on nut 7
