Specific embodiment
Below in conjunction with the accompanying drawings and embodiment specifically describes to the present invention.
The present invention includes bearing unit 1, thrust washer 2, adjusting nut 3 and snap ring 4.
Described bearing unit 1 is supported on axle 5, and thrust washer 2 is coordinated with bearing unit 1 plane.
Fig. 2 show the structural representation of adjusting nut of the present invention.
Described adjusting nut 3 is outside to be hierarchic structure, is provided with anti-slip tank in the outer of adjusting nut 3.
Described adjusting nut 3 is internal to be female thread structure, and this female thread structure is mated with the screw thread on axle 5；In female thread
One end of structure is provided with annular groove 6.
Fig. 3 show the structural representation of snap ring of the present invention.
Described snap ring 4 is made up of Maranyl, has higher toughness and intensity.May also be employed other have higher
Toughness and the material of intensity.
The internal diameter of described snap ring 4 is coordinated with the thread interference on axle 5.
Fig. 4 show the generalized section after snap ring of the present invention is pressed into adjusting nut.
It is rigidly connected, do not have relative motion with adjusting nut 3 in the annular groove 6 of described snap ring 4 force fit adjusting nut 3.
Fig. 1 show the assembling schematic diagram of the present invention.
Described bearing unit 1 is supported on axle 5, and the two plane coordinates；Thrust washer 2 and the cooperation of bearing unit 1 plane and
Axle 5 plane coordinates；Adjusting nut 3 is threadeded with axle 5 and the cooperation of thrust washer 2 plane, the spiral shell on the internal diameter of snap ring 4 and axle 5
Stricture of vagina interference fit.
The method of adjustment of the present invention：
First, by interior for the annular groove 6 of snap ring 4 force fit adjusting nut 3 so as to be rigidly connected with adjusting nut 3 there is no phase
To motion；
Thrust washer 2 is placed on axle 5 and coordinates with bearing unit 1 plane；
Then tighten adjusting nut 3, realize the axial limiting of bearing unit 1, the adjusting nut 3 after tightening ensures that wheel hub turns
Dynamic flexible.
When adjusting nut 5 automatic rotary or lax when, be arranged on the snap ring 4 of adjusting nut 3 and the screw thread on axle 5 occur
Relative motion trend, produces stiction and realizes locking.
Adjusting nut 3 can be reused：After snap ring 4 lost efficacy, to adjusting nut 3 mating surface cleaning treatment, then change
Snap ring 4 can achieve the reuse of adjusting nut 3.
The operation principle of the present invention：
Adjusting nut 3 of the present invention is threadeded with axle 5, axle 5 and bearing unit 1 or hub-bearing unit axial direction
Plane coordinates；Adjusting nut 3 and the cooperation of thrust washer 2 plane, realize axial limiting；Thrust washer 2 and the cooperation of axle 5 plane, with
Limit the rotation of axle 5；Thrust washer 2 and the cooperation of bearing unit 1 plane, to realize the axial limiting of bearing unit 1；Adjusting nut
3 carry out axial limiting to bearing unit 1 indirectly by thrust washer 2；Snap ring 4 force fit adjusting nut 3, with adjusting nut 3
There is no relative motion, coordinate with the thread interference on axle 5, by the rotation of snap ring 4 and the friction power restriction adjusting nut 3 of screw thread
Turn, and then limit the rotation of bearing unit 1, realize locking effect.
The present invention is compared with the prior art：
1) compare with opening pin adjusting nut：
Need adjusting nut groove with the hole mated on axle to it, in order to opening during the assembling of opening pin adjusting nut
The assembling of pin；The adjusting nut of the present invention, then without the concern for this problem, also save dress this operation of split pin simultaneously, carry
High efficiency of assembling, and avoid and come off the fault leading to because of split pin, long service life.
2) compare with sheet type adjusting nut：
During the assembling of sheet type adjusting nut, after tightening adjusting nut, the thin slice on adjusting nut is knocked on coupling axle
Groove；The adjusting nut of the present invention, saves the thin slice that will hit against on adjusting nut and knocks in coupling this operation of axle it is only necessary to twist
Tight adjusting nut, easy to assembly.Join efficiency high, it also avoid adjusting nut thin slice simultaneously and lost efficacy or adjusting nut locking
Disabler.
In the built-in snap ring of adjusting nut, snap ring and axle interference fit, by the friction between snap ring and axle thread for the present invention
Resistance realizes the locking of adjusting nut.Only need to during adjustment to tighten adjusting nut and can achieve, have that structure is simple, assembling side
Just, the advantage of efficiency high and long service life, the locking mechanism relatively commonly used at present, it is more suitable for bearing unit and hub bearing
Unit.
The embodiment above of the present invention, is merely illustrative, and is not only, all within the scope of the present invention or equivalent this
Change in the range of invention is all surrounded by the present invention.
