Technical Field
The utility model relates to a bearing technical field especially relates to a bearing for automobile ABS motor.
Background
The bearing is a component for fixing and reducing the load friction coefficient in the mechanical transmission process. It can also be said that the member for reducing the friction coefficient during power transmission and keeping the center position of the shaft fixed when the other members are moved relative to each other on the shaft. The bearing is a lightweight part in modern mechanical equipment. Its main function is to support the mechanical rotating body to reduce the friction coefficient of mechanical load of equipment in the transmission process.
The existing bearing is directly installed on the motor, and because the motor bearing belongs to a high-rotating-speed bearing, the ultrahigh rotating speed can generate high-frequency vibration in the operation process, and the motor with the failed bearing is finally scrapped due to the displacement caused by the vibration and the service life.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem who solves: the bearing for the automobile ABS motor is provided with the special-shaped anti-drop rubber ring after the outer diameter of the bearing is grooved aiming at the defects in the prior art.
The utility model provides a technical problem can adopt following technical scheme to realize:
a bearing for an automobile ABS motor comprises a bearing outer ring and a bearing inner ring, wherein a retainer is arranged between the bearing outer ring and the bearing inner ring, and balls are arranged in a ball pocket of the retainer; the bearing is characterized in that three annular grooves are formed in the outer ring surface of the bearing outer ring, and a special-shaped anti-falling rubber ring is arranged in each annular groove.
In a preferred embodiment of the present invention, the three annular grooves are uniformly distributed around the middle of the outer annular surface of the bearing outer ring.
In a preferred embodiment of the invention, each annular groove radial section is constituted by an approximately drum-shaped groove located on the inside and an approximately cylindrical groove located on the outside.
In a preferred embodiment of the present invention, the inner annular surface of the bearing outer ring and the outer annular surface of the bearing inner ring are both provided with an annular arc-shaped groove for limiting movement of the balls.
Due to the adoption of the technical scheme, the beneficial effects of the utility model reside in that: the special-shaped anti-falling rubber ring arranged on the outer ring surface of the bearing outer ring is matched with the bearing seat, so that the bearing is fixed in the bearing seat, and the anti-falling structure of the rubber ring cannot fall off in the installation process, so that the bearing is positioned. The anti-falling rubber ring arranged in the annular groove can effectively solve the influence of vibration generated by the motor in a high-rotating-speed state on the bearing by utilizing the characteristic of good rubber elasticity, and can provide better sealing performance. The performance of the bearing cannot be influenced by load change of bearing displacement caused by long service time; the annular arc-shaped grooves on the inner ring surface of the bearing outer ring and the outer ring surface of the bearing inner ring enhance the stability of the balls in the bearing during working.

Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.
Referring to fig. 1 to 3, the bearing for the ABS motor of the automobile is shown to be installed in a bearing seat, and includes a bearing outer ring 10, a bearing inner ring 20, a retainer 30, a pair of sealing rings 40, a plurality of balls 50, and three irregular anti-drop rubber rings 60 installed on an outer ring surface, wherein the retainer 30 is disposed between the bearing outer ring 10 and the bearing inner ring 20, a plurality of ball pockets 31 are uniformly distributed on the retainer 30, and the balls 50 are disposed in the ball pockets 31, so that the load of the bearing is effectively uniform.
One seal ring 40 is installed between the bearing outer ring 10 and the bearing inner ring 20 on both left and right sides in the axial direction of the retainer 30, respectively, to prevent dust from entering the inside of the bearing. Annular arc grooves 11 and 21 for limiting movement of the balls 50 are formed in the inner annular surface of the bearing outer ring 10 and the outer annular surface of the bearing inner ring 20.
Three annular grooves 12 are provided on the outer circumferential surface of the bearing outer ring 10 centering on the middle of the outer circumferential surface of the bearing outer ring 10, and each of the annular grooves 12 is formed with an approximately drum-shaped groove 12a and an approximately cylindrical groove 12b in the radial section, wherein the approximately drum-shaped groove 12a is located on the inner side and the approximately cylindrical groove 12b is located on the outer side.
The three annular grooves 12 are internally provided with special-shaped anti-falling rubber rings 60, and the special-shaped anti-falling rubber rings 60 positioned in the approximately drum-shaped grooves 12a partially bulge outwards, so that the special-shaped anti-falling rubber rings 60 can be prevented from falling out of the annular grooves 12.
The outer annular surface of the bearing outer ring 10 is matched with the bearing seat, so that the bearing is fixed in the bearing seat, and the special-shaped anti-falling rubber ring 60 cannot fall off in the installation process, so that the positioning effect is achieved.
The special-shaped anti-drop rubber ring 60 arranged in the annular groove 12 can effectively solve the problem of influence of vibration generated by the motor in a high rotating speed state on the bearing by utilizing the characteristic of good rubber elasticity. The performance of the bearing cannot be influenced by load change of bearing displacement caused by long service time; the annular arc grooves 11, 21 on the inner circumferential surface of the bearing outer ring 10 and the outer circumferential surface of the bearing inner ring 20 enhance the stability of the balls 50 in the bearing in operation.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
