Embodiment Construction

[0015] The present invention will be further described now in conjunction with accompanying drawing.

[0016] see figure 1 , figure 2 with image 3 , the present invention designs a slotted round nut provided with variable-tooth-type anti-loosening threads, including a slotted round nut body and a slotted round nut internal thread. There is a wedge-shaped slope 3 at the bottom of the slotted round nut internal thread 2 of the slotted round nut body 1, and the angle between the wedge-shaped slope 3 and the reverse extension line of the lower plane of the slotted round nut internal thread 2 is 30° . The angle between the lower plane and the upper plane of the slotted round nut internal thread 2 is 60°. A phosphating layer is provided on the surface of the internal thread 2 of the slotted round nut, and a phosphating layer is provided on the surface of the wedge-shaped slope 3 . The slotted round nut body 1 is a slotted round nut with a specification of M60×1.5mm.

Abstract

The invention relates to the technical field of mechanic, in particular to a grooved round nut with a variable tooth type anti-loosening thread. The grooved round nut with the variable tooth type anti-loosening thread includes a grooved round nut body and a grooved round nut inner thread. A wedge inclined plane is arranged at the tooth bottom of the grooved round nut inner thread of the grooved round nut body. The angle between the wedge inclined plane and the reverse extension line of lower plane of the grooved round nut inner thread is 30 degrees. Compared with the prior art, the wedge inclined plane of 30 degrees is added at the tooth bottom of the grooved round nut inner thread, so that great locking force is produced when a bolt are screwed with the grooved round nut, the problem thatthe grooved round nut on pressing position of an axle hub bearing is prone to loosening, is avoided; and phosphating layers are correspondingly added on the surface of the grooved round nut inner thread and the surface of the wedge inclined plane, so that it is ensured that the clamping force of threaded connection is stable, and the phosphating layers play a role of rust prevention.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a slotted round nut provided with variable tooth-type anti-loosening threads. Background technique [0002] With the development of the automobile industry, the requirements for automobile fasteners are getting higher and higher. The existing slotted round nuts have insufficient locking force, which leads to easy loosening of the slotted round nuts at the compression parts of the axle hub bearings. Therefore, it is very important to design a slotted round nut with variable tooth anti-loosening thread that can improve the locking force. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art, and provide a slotted round nut with a variable tooth anti-loosening thread that can improve the locking force. [0004] In order to achieve the above-mentioned purpose, the present invention designs a slotted round nut pro...
