BACKGROUND

[0002] The anti-vibration and anti-loose wheel hub wedge locking nut is a technical upgrade version of the anti-vibration and anti-loose wedge locking nut developed by Mr. Huang Linchuan.

[0003] The anti-vibration and anti-loose wedge locking nut technology inherits the wedge fastening principle in the traditional Chinese five-thousand-year technology, so that the nut realizes both upward and downward fastening and also realizes horizontal fastening, so that the nut has super strong anti-vibration and anti-loose performance.

[0004] The anti-vibration and anti-loose wedge locking nut has undergone high-frequency vibration experiments of various specifications and models in the national general parts quality supervision and detection center in accordance with the national horizontal vibration experiment standard (GB / T 1043 12008), and the detection data shows that the fastening and stability of our wedge locking nut reaches 95%-99%.

[0005] The anti-vibration and anti-loose wheel hub wedge locking nut is an upgraded version of the wedge locking nut mainly suitable for the automobile field according to the substantial needs of various automobile fields. SUMMARY

[0006] The anti-vibration and anti-loose wheel hub wedge locking nut structure is composed of a wedge nut (1) and a sleeve nut (2); a bolt (3) and a bolt thread (9); the wedge nut (1) has an arc wedge platform (4), a conical base (5), a wedge nut thread (11), and an (r) wedge platform angle; the sleeve nut (2) has a wedge groove (6), an (m) wedge groove angle, a sleeve top (7), a threaded hole groove (8), and a (10) sleeve nut thread; the fastened object (12) is the object clamped when the wedge nut (1) and the sleeve nut (2) are fastened with the bolt (3), and the arc of the arc wedge platform (4) on the wedge nut (1) is less than or equal to 180 degrees.

[0015] Marked in the figure: wedge nut (1); sleeve nut (2); bolt (3); arc wedge platform (4); conical base (5); wedge groove (6); sleeve top (7); threaded hole groove (8); bolt thread (9); sleeve nut thread (10); wedge nut thread (11); fastened object (12); wedge platform angle (r); wedge groove angle (m). DETAILED DESCRIPTION

[0016] The "anti-vibration anti-loose hub wedge nut" should be screwed on the bolt (3) first during use, after clamping the fastened object (12), tighten 60%-80% according to the standard torque of different specifications and models of nuts, then screw the sleeve nut (2) onto the bolt (3), the two nuts of the wedge nut (1) and the sleeve nut (2) are screwed together, the sleeve nut (2) is tightened to 100% according to the standard torque of different specifications and models of nuts, in this way, the wedge nut (1), the sleeve nut (2) and the bolt (3) realize both upward and downward fastening and also realize horizontal fastening.

[0017] The wedge platform angle (r) of the arc wedge platform (4) on the wedge nut (1) is the same as the wedge groove angle (m) in the wedge groove (6) of the sleeve nut (2), which makes the inclined surface of the arc wedge platform (4) and the inclined surface of the wedge groove (6) fit together when the wedge nut (1) and the sleeve nut (2) are fastened to each other. Thus, the "anti-vibration anti-loose hub wedge nut" realizes both upward and downward fastening and also realizes horizontal fastening, thereby realizing the principle of "crossed fastening", so that the "anti-vibration anti-loose hub wedge nut" has super strong anti-vibration and anti-loose performance, even in the process of long-term high-frequency strong vibration, the hub wedge nut is not easy to loosen.

[0018] The "anti-vibration anti-loose hub wedge nut" is mainly produced by two production processes: one is numerical control precision machining process; the other is die upsetting process.

[0019] The numerical control precision machining process of the anti-vibration and anti-loose wheel hub wedge lock nut can be carried out by numerical control lathe and numerical control milling machine, or numerical control turning and milling combined lathe, or numerical control walking heart machine tool. This process has high precision and slightly high cost, and is mainly applied to some high-end and precision mechanical equipment of the country, such as aviation, aerospace, high-speed train, precision equipment and the like.

[0020] The die upsetting process of the anti-vibration and anti-loose wheel hub wedge lock nut is to customize various types of molds for various types of wheel hub wedge lock nuts, and each type of mold is divided into a wedge nut (1) mold and a sleeve nut (2) mold. Then, through the cold upsetting or hot upsetting production process, the raw material block is upset into the shape of the wedge nut (1) and the sleeve nut (2), and then the numerical control lathe is used for shape finishing, so as to complete the die upsetting process of the anti-vibration and anti-loose wheel hub wedge lock nut. The die upsetting process has the characteristics of low precision, low cost, wide application field, etc., and is mainly applied to the middle-end market which has not high precision requirement for nuts, such as rail transit, building bridge, national power, mine exploration, mechanical equipment and the like.

[0021] The nut standard of the anti-vibration and anti-loose wheel hub wedge lock nut can match various types of bolts of national standard and various international bolt standards.

[0022] The anti-vibration and anti-loose wheel hub wedge lock nut can be produced and processed by using various metal materials and composite materials to adapt to various fields of society.
