Method used

Wherein, in order to realize the purpose that dustproof cover 22 is installed, this device adopts following technical scheme to realize: bearing outer ring 1 both sides inner walls are all fixedly connected limit ring 19, two limit rings 19 opposite side surfaces are An annular groove 20 is provided, and a sealing ring 21 is provided in the two annular grooves 20, and a dust cover 22 is provided on the opposite side of the two limit rings 19, and the outer wall of the dust cover 22 is socketed with the bearing outer ring 1 to prevent The inner wall of the dust cover 22 is rotatably connected with the outer wall of the bearing inner ring 2. An extrusion ring 23 is fixedly connected to one side of the dust cover 22. The extrusion ring 23 is inserted into the limit ring 19 through the annular groove 20. The dismounting assembly is symmetrically arranged, and the dismounting assembly includes a movable block 24 and a second spring 25. The surface of the dust cover 22 is provided with a movable groove 26, and the movable block 24 is slidably connected with the dustproof cover 22 through the movable gr...

Abstract

According to the technical scheme, the pretightening force adjustable precise combination bearing comprises a bearing outer ring, a bearing inner ring is coaxially arranged on the inner side of the bearing outer ring, a plurality of balls are arranged between the bearing outer ring and the bearing inner ring and distributed in a circumferential array mode, retainers are arranged on the two sides between the bearing outer ring and the bearing inner ring, and the retainers are arranged on the two sides between the bearing outer ring and the bearing inner ring. The precise combination bearing with the adjustable pretightening force has the beneficial effects that the pretightening adjusting mechanism is arranged, the adjusting bolt is limited through the locking nut, so that the spacing distance between the two retainers can be adjusted, and the pretightening force is adjusted through elastic extrusion of the first spring, so that the pretightening force is adjusted, and the precision of the pretightening force is improved. According to the retainer for the ball bearing, by arranging the arc-shaped plates, every two opposite arc-shaped plates can clamp the balls to different degrees, so that pre-tightening force adjustment is achieved, and the problems that the pre-tightening force of an existing retainer for the ball bearing is fixed during installation, adjustment cannot be conducted according to the sizes of the balls or actual situation needs, and use is inconvenient during combination and assembly are effectively solved.
