Abstract
The utility model relates to the technical field of machinery, in particular to a nut with variable thread form type anti-loose threads. The nut with the variable thread form type anti-loose threads comprises a nut body and inner threads, wherein a wedge-shaped inclined plane is arranged at the lower portion of teeth of the inner threads of the nut body, and an included angle between the wedge-shaped inclined plane and a reverse extending line of a lower plane of the inner threads is 30 degrees. Compared with the prior art, due to the facts that the 30-degree wedge-shaped inclined plane is added to the lower portion of the teeth of the inner threads of the nut body, the nut with the variable thread form type anti-loose threads generates great tight locking force when a bolt and the nut are mutually tightened, and the problem that the nut arranged at a compressing position of an axle hub bearing is prone to loose is avoided. Phosphate coating layers are added to the surface of the inner threads and the surface of the wedge-shaped inclined plane, and therefore clamp force of threaded connection is enabled to be stable and the phosphate coating layers have an antirust function.
Description
Technical field
The utility model relates to field of mechanical technique, specifically a kind of nut that is provided with the variable-tooth type checknut.
Background technique
Along with the development of car industry, more and more higher to the requirement of fastening parts of automobiles.Existing nut check power is not enough, thereby the nut that causes the axle hub bearing to compress the position easily occurs loosening.Therefore, a kind of nut that is provided with the variable-tooth type checknut that can improve nut check power of design is vital.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of nut that is provided with the variable-tooth type checknut that can improve nut check power is provided.
In order to achieve the above object, the utility model has designed a kind of nut that is provided with the variable-tooth type checknut, comprise nut body and internal thread, it is characterized in that: the internal thread tooth bottom of nut body is provided with a wedge shape inclined-plane, and the angle between described wedge shape inclined-plane and described internal thread lower plane reverse extending line is 30 °.
Angle between described internal thread lower plane and upper plane is 60 °.
Described interior threaded surface is provided with phosphating coating.
Described wedge shape chamfered surface is provided with phosphating coating.
Described nut body is grooved round nut or locking nut, and the specification of grooved round nut is M88 * 1.5mm, and the specification of locking nut is M80 * 1.5mm or M85 * 1.5mm.
The utility model is compared with prior art, sets up the wedge shape inclined-plane of 30 ° in nut inner thread tooth bottom, when bolts and nuts are tightened mutually, produces very large coupling mechanism force, and loosening problem easily appears in the nut of having avoided the axle hub bearing to compress the position; Set up respectively phosphating coating in interior threaded surface and wedge shape chamfered surface, guarantee that the clamping force that is threaded is stable, and played antirust effect.

Referring to Fig. 1, Fig. 2 and Fig. 3,1 is nut body; 2 is internal thread; 3 is the wedge shape inclined-plane.
Embodiment
Now by reference to the accompanying drawings the utility model is described further.
Referring to Fig. 1, Fig. 2 and Fig. 3, the utility model has designed a kind of nut that is provided with the variable-tooth type checknut, comprises nut body and internal thread.The internal thread 2 tooth bottoms of nut body 1 are provided with a wedge shape inclined-plane 3, and the angle between wedge shape inclined-plane 3 and internal thread 2 lower plane reverse extending lines is 30 °.Angle between internal thread 2 lower planes and upper plane is 60 °.Internal thread 2 surfaces are provided with phosphating coating, and 3 surfaces, wedge shape inclined-plane are provided with phosphating coating.Nut body 1 is that the grooved round nut of M88 * 1.5mm or locking nut or specification that specification is M80 * 1.5mm are the locking nut of M85 * 1.5mm for specification.
When the utility model was screwed into nut at bolt, the externally threaded cusp of bolt withstood on the wedge shape inclined-plane 3 of internal thread 2, produces very large coupling mechanism force, has reached the purpose that prevents nut loosening.
The utility model is set up the wedge shape inclined-plane 3 of 30 ° in the internal thread 2 tooth bottoms of nut body 1, when bolts and nuts are tightened mutually, produce very large coupling mechanism force, and loosening problem easily appears in the nut of having avoided the axle hub bearing to compress the position; Set up respectively phosphating coating on internal thread 2 surfaces and 3 surfaces, wedge shape inclined-plane, guarantee that the clamping force that is threaded is stable, and played antirust effect.
