Detailed Description

In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.

As shown in fig. 1-4, a low-noise bearing comprises an inner ring 10 and an outer ring 11, a retainer 12 is arranged between the inner ring 10 and the outer ring 11, at least two balls 13 are arranged on the retainer 12, the balls 13 are uniformly distributed on the retainer 12 along the circumferential direction of the retainer 12, two first clamping grooves are formed in the outer end face of the inner ring 10, two second clamping grooves are formed in the inner end face of the outer ring 11, a sealing gasket 14 is detachably arranged between the first clamping grooves and the second clamping grooves which are located on the same horizontal line, and lubricating oil is filled between the two sealing gaskets 14.

In the embodiment, a mounting block 15 is arranged on the retainer 12 between two adjacent balls 13, and an abutting component is arranged in each mounting hole 15;

the butt subassembly is equipped with location axle 16 including setting up the direction of height along holder 12 in placing hole 15, and location axle 16 goes up the cover and is equipped with two backup pads 17 through the torsional spring, is equipped with a butt section of thick bamboo 18 between two backup pads 17, still is equipped with clutch blocks 19 on the end wall that lies in backup pad 17 and keep away from a butt section of thick bamboo 18 on placing hole 15, and clutch blocks 19 is the semicircle setting towards a side end face of backup pad 17.

Under the initial state, under the action of the friction force of the abutting block 19, the two support plates 17 are positioned in the arrangement hole 15, at the moment, the torsion spring sleeved between the support plates 17 and the positioning shaft 16 is in a force storage state, along with the running of the bearing, the grooves of the inner ring and the outer ring of the bearing and the outer surfaces of the balls are worn, the distance between the two grooves of the inner ring and the outer ring of the bearing is increased, the retainer 12 drives the balls 13 to shake between the inner ring and the outer ring of the bearing, the retainer 12 drives the balls 13 to collide with the inner ring and the outer ring of the bearing when shaking between the inner ring and the outer ring of the bearing, under the action of the external impact force, the support plates 17 overcome the friction of the friction block 19, under the action of the torsion spring between the support plates 17 and the positioning shaft 16, the support plates 17 rotate on the positioning shaft 16, the abutting cylinder 18 is abutted against the outer end surface of the inner ring or the inner end surface of the outer ring of the bearing, and the stability of the retainer 12 and the balls 13 between the inner ring and the inner ring of the bearing is ensured, when the retainer 12 and the plurality of balls 13 shake, the condition that the balls and the inner and outer rings of the bearing are abraded more quickly and the service life of the bearing is shortened is avoided;
