Abstract
The invention relates to a nut, in particular to a high-strength nut. The high-strength nut comprises a primary nut connected with a bolt or a stud in a pre-tightening mode, a secondary nut and an adjustment gasket, wherein the primary nut is composed of a primary nut reinforcing portion and a primary nut pre-tightening portion, and a transition position between the primary nut reinforcing portion and the primary nut pre-tightening portion is provided with an unloading groove; inner threads connected with the bolt or the stud in a pre-tightening mode are arranged on the primary nut and run through the entire primary nut; the primary nut reinforcing portion is provided with outer threads, the outer threads and the secondary nut can be connected in a screwing-up mode, and the adjustment gasket for adjusting the distance between the primary nut and the secondary nut is arranged between the primary nut and the secondary nut. By the adoption of the high-strength nut, the thread pitch of the inner threads of the primary nut is manually adjusted through tensile elastic deformation generated when the primary nut reinforcing portion and the secondary nut are screwed up, elastic deformation generated when teeth of the inner threads of the primary nut are loaded is compensated, further the number of the teeth of connecting threads participating in load bearing is increased, the connecting strength is improved, and the problems of low threaded connecting strength and poor reliability are solved.
Description
Technical field
The present invention relates to a kind of nut, specifically a kind of high strength nut.
Background technique
In the scyewed joint of routine, between nut and bolt, transmit screwing force by worm tooth, realize the compression of workpiece.In the connection process of reality, screw thread tooth can produce resiliently deformable due to stressed, pitch is changed, the worm tooth of actual bearing load is caused to be only limitted to 3-5 tooth of bottom, all the other teeth do not bear or bear very little load, therefore when using, bearing capacity is low, and when withstanding shocks load, nut easily loosens, and greatly limit intensity and the reliability of scyewed joint.
Summary of the invention
The present invention seeks to the deficiency produced for overcoming above-mentioned technical problem, a kind of high strength nut being provided, by artificially adjusting thread pitch, compensating the resiliently deformable that screw thread tooth stand under load produces, and then increase the number of teeth of the connection screw thread participating in carrying, greatly can improve the intensity of connection.
The present invention for solving the problems of the technologies described above adopted technological scheme is: a kind of high strength nut, comprises with mother nut, the secondary nut of bolt or stud coupling and adjusts pad; Described mother nut is made up of mother nut reinforcing part and mother nut pretension portion, is provided with spron between mother nut reinforcing part and mother nut pretension portion; Run through whole mother nut and be provided with internal thread with bolt or stud coupling; Described mother nut reinforcing part is provided with outside thread, and set outside thread can be tightened with secondary nut and connect, and is provided with the adjustment pad of adjustment distance between mother nut and secondary nut.
Described mother nut pretension portion is multi-sided hollow prism, and described hollow prism body is hexagon hollow prism body or four limit hollow prism bodies etc.
Described mother nut reinforcing part is hollow cylinder.
Beneficial effect is: a kind of high strength nut of the present invention, design ingenious, comprise mother nut, secondary nut and adjustment pad, mother nut is provided with inside and outside two-layer screw thread, during use, mother nut internal thread and bolt or stud coupling, mother nut outside thread and secondary nut coupling, for adjusting the spacing of mother nut and secondary nut, between mother nut and secondary nut, be provided with adjustment pad.The present invention is by the pitch of the tensile elasticity distortion artificial adjustment screw thread of mother nut reinforcing part, compensate the resiliently deformable that mother nut internal thread tooth stand under load produces, and then increase the number of teeth of the connection screw thread participating in carrying, improve the intensity connected, solve the problem of the low and poor reliability of screw thread connection strength.
Accompanying drawing explanation
Fig. 1 is the three dimensional sectional view of high strength nut of the present invention;
Fig. 2 is the plan view of high strength nut of the present invention;
In figure, mark is: 1, mother nut, 11, mother nut reinforcing part, 12, mother nut pretension portion, 2, secondary nut, 3, adjustment pad.
Embodiment
As shown in the figure, a kind of high strength nut, comprises with mother nut 1, the secondary nut 2 of bolt or stud coupling and adjusts pad 3.Described mother nut 1 is made up of mother nut reinforcing part 11 and mother nut pretension portion 12, and the two is as a whole, and concentrate for reducing stress, intermediate location is provided with spron; Run through whole mother nut 1 and be provided with the internal thread connected with bolt or stud; Described mother nut reinforcing part 11 is provided with outside thread, and set outside thread can be tightened with secondary nut 2 and connect, and is provided with the adjustment pad 3 of adjustment distance between mother nut and secondary nut.
Described mother nut pretension portion 12 profile is multi-sided hollow prism, and described hollow prism body is hexagon hollow prism body or four limit hollow prism bodies etc.; Described mother nut reinforcing part 11 profile is hollow thin-wall cylindrical body.
High strength nut of the present invention, in use, first mother nut 1 spiral is tightened on bolt or stud, then getting adjustment pad 3 overlaps on the mother nut reinforcing part 11 of mother nut 1, finally by secondary nut 2 spiral on mother nut reinforcing part 11, and apply screwing force make mother nut reinforcing part entirety occur tensile elasticity distortion, mother nut reinforcing part internal thread pitch is changed, and then increase the quantity of the screw thread tooth that mother nut connects with bolt or stud, increase substantially linking intensity and reliability.
