Description of the embodiments
The utility model is described in further detail below with reference to the drawings and the detailed description.
As shown in fig. 1, 2 and 3, the bearing special for the electric air conditioner press of the new energy automobile comprises an outer ring 1, an inner ring 3, a retainer 4 and balls 5, wherein the retainer comprises an annular main body, pockets 9 are arranged on the upper portion of the annular main body along the circumferential direction at intervals, the balls 5 are respectively arranged in the corresponding pockets 9 in a one-to-one correspondence manner, and the pockets 9 are arranged in a cylindrical manner along the radial direction of the annular main body. I.e. the pocket is of an open cylindrical shape, which is different from the prior art, in that the ball 5 can move to a certain extent in the direction of the center of the cylindrical shape, i.e. in the radial direction of the cage 4. When the bearing works in the electric air conditioner press of the new energy automobile, the bearing not only rotates, but also rotates at the same time, in the rotating process, the balls generate centrifugal force to act on the retainer 4, while the conventional bearing adopts a spherical pocket, the balls are limited in the spherical pocket, the centrifugal force acts on the retainer, the retainer is mainly made of nylon materials, and after a certain degree, the condition of fracture and the like can occur, so that the service life of the bearing is greatly reduced. The pocket is designed to be cylindrical, so that in the radial direction of the retainer, the balls 5 have a certain movement space, and in the process of revolution, centrifugal force acts on the inner wall of the bearing outer ring 1, the bearing outer ring is made of metal, and the centrifugal force has little influence on the service life of the bearing outer ring.
A connecting part 7 is arranged between the pocket holes, a first groove 8 is formed in the connecting part 7, and the width of the first groove 8 gradually decreases from the radial outer side to the radial inner side. The bottom of the annular main body is inwards provided with a second groove 2 corresponding to the position of the connecting part, and the two circumferential sides of the second groove 2 are in arc connection with the bottom surface of the annular main body. The first groove and the second groove are arranged to reduce the weight of the retainer, thereby reducing the acting force of the retainer in the high-speed movement process.
The connecting portions on two sides of the first groove extend upwards in an arc shape along the pocket walls of the corresponding pockets to form holding claws 10, the pocket walls on two sides of each pocket extend upwards in an arc shape to form holding claws 10, and one side, far away from the pocket, of each holding claw is arranged obliquely upwards from the bottom surface of the first groove. The top end arc surfaces 11 of the opposite surfaces of the holding claws on both sides of each pocket are provided. The holding claw is in order to limit the ball in the pocket, because the pocket cylindricality sets up, then in holding claw top position, the appearance matching nature with the ball is relatively poor, carries out the arcwall face setting with its top, guarantees the matching nature with the ball, reduces the frictional force that causes because of the matching problem.
Arc grooves are formed in the positions, corresponding to the balls, of the outer surface of the inner ring and the inner surface of the outer ring, and arc guide angles are formed at the edges of the inner ring and the outer ring. The inner diameter of the inner ring is 15mm, the outer diameter of the outer ring is 42mm, the height of the outer ring is 11mm, and 7 pockets are arranged. The size bearing is the size of the special bearing of the electric air conditioner press of the new energy automobile.
The pocket hole is designed to be columnar along the radial direction by the existing spherical shape, then in the working process, the balls are not limited in the radial direction, the centrifugal force acts on the inner wall of the outer ring, namely, the inner wall of the outer ring bears the centrifugal force, so that the retainer cannot break, the outer ring is made of metal, the service life of the retainer cannot be influenced, and the service life of the bearing is prolonged.
According to the utility model, through redesigning the pocket holes on the retainer, the bearing can transfer the bearing direction of centrifugal force to the bearing outer ring under the revolving working condition, so that the influence on the retainer is reduced, the service life of the retainer is prolonged, and the service life of the bearing is prolonged.
