Abstract

The adjusting nut for the drive axle of the utility model comprises an annular ring body, an internal thread arranged in the inner hole of the ring along the circumferential direction, a plurality of protruding teeth arranged on one side of the ring body along the circumferential direction, and a plurality of protruding teeth arranged on one side of the ring body along the circumferential direction and arranged on the ring along the circumferential direction. Several inwardly concave grooves on the other side of the body. When the nut is tightened, a steel roller can be inserted into the tooth groove between two adjacent convex teeth, and the top of the steel roller can push the convex tooth to drive the ring body to rotate by knocking the steel roller, so that the driving axle can be gradually used Tighten the adjusting nut. It solves the problem that conventional tools cannot be used to tighten the nut due to the limited space. Since one side of the ring body is provided with a groove, the lubricating oil can flow from the groove into the bearing adjacent to the adjusting nut of the driving axle after installation, which improves the lubrication performance of the adjacent surface of the bearing and the nut. After the nut is tightened, the flange of the dust cover on the flange is inserted into the groove, so the interlacing of the flange of the dust cover and the groove improves the sealing performance and effectively prevents the entry of dust.

Description

Adjusting nut for drive axle

technical field

The utility model relates to the technical field of auto parts, in particular to an adjusting nut for a drive axle.

Background technique

At present, during the assembly process of the drive axle, it is inconvenient to tighten and adjust the nuts in the axle to adjust the preload of the bearings. The contact surface between the nuts and the bearings affects the lubrication of the bearings and has a certain impact on the life of the bearings. There are certain restrictions in the design of the bridge, which is not conducive to dust prevention in the bridge.

Contents of the invention

In order to overcome the deficiencies of the above technologies, the utility model provides an adjusting nut for a drive axle that is convenient for tightening and adjusting and has a good lubricating and dustproof effect.

The technical solution adopted by the utility model to overcome its technical problems is:

The adjusting nut for the drive axle includes a circular ring body, an internal thread arranged in the inner hole of the ring along the circumferential direction, a number of protruding teeth arranged on one side of the ring body along the circumferential direction and arranged on the other side of the ring body along the circumferential direction. There are several inwardly recessed grooves on one side, a tooth groove is formed between every two adjacent protruding teeth, and the side of the ring adjacent to the protruding teeth is provided with a dust-proof device that is concave toward the direction of the groove along the circumferential direction. Groove, the groove width of the dust-proof groove matches the outer edge of the dust-proof cover of the flange.

The beneficial effect of the utility model is: when the nut is tightened, the steel roller can be inserted into the tooth groove between two adjacent convex teeth, and the top of the steel roller pushes the convex tooth to drive the ring body to rotate by knocking the steel roller. The drive axle can be tightened gradually with the adjusting nut. It solves the problem that conventional tools cannot be used to tighten the nut due to the limited space. Since one side of the ring body is provided with a groove, the lubricating oil can flow from the groove into the bearing adjacent to the adjusting nut of the driving axle after installation, which improves the lubrication performance of the adjacent surface of the bearing and the nut. After the nut is tightened, the flange of the dust cover on the flange is inserted into the groove, so the interlacing of the flange of the dust cover and the groove improves the sealing performance and effectively prevents the entry of dust.

Detailed ways

Below in conjunction with accompanying drawing 1, accompanying drawing 2, accompanying drawing 3 the utility model is described further.

The adjusting nut for the drive axle includes a circular ring body 1, an internal thread 2 arranged in the inner hole of the ring body 1 along the circumferential direction, several convex teeth 3 arranged on one side of the ring body 1 along the circumferential direction, and The direction is provided on the other side of the ring body 1 with several inward recessed grooves 5, and a tooth groove 4 is formed between every two adjacent convex teeth 3, and the side of the ring body 1 adjacent to the convex teeth 3 A dust-proof groove 6 recessed toward the groove 5 is provided along the circumferential direction, and the groove width of the dust-proof groove 6 matches the outer edge of the dust-proof cover 8 of the flange 7 . When tightening the nut, a steel roller can be inserted into the tooth groove 4 between two adjacent convex teeth 3, and the top of the steel roller can push the convex tooth 3 to drive the ring body 1 to rotate by tapping the steel roller, so that the ring body 1 can be gradually tightened. The drive axle is tightened with an adjusting nut. It solves the problem that conventional tools cannot be used to tighten the nut due to the limited space. Since one side of the ring body 1 is provided with a groove 5, the lubricating oil can flow from the groove 5 into the bearing adjacent to the adjusting nut of the driving axle after installation, which improves the distance between the adjacent surface of the bearing and the nut. lubricating properties. After the nut is tightened, the flange of the dust cover 8 on the flange 7 is inserted into the groove 5, so the interlacing of the flange of the dust cover 8 and the groove 5 improves the sealing performance and effectively prevents the entry of dust.
