Abstract
The utility model discloses a locknut assembly for a rotating shaft. The locknut assembly comprises a fastening thread, a locking thread, a clamp nut and a lock nut, wherein the fastening thread and the locking thread are sequentially arranged on the rotating shaft from outside to inside along the rotating shaft; the spiral direction of the fastening thread is opposite to that of the locking thread, the outer diameter of the locking thread is larger than that of the fastening thread, and the length of an internal thread of the clamp nut is larger than the length of the fastening thread. The locknut assembly for the rotating shaft solves the technical problem that lock nuts on the rotating shaft get loose easily, and is simple in structure and excellent in using effect.
Description
Technical field
The utility model relates to hot-rolled steel section field, and particularly, the utility model relates to a kind of for the anti-loosen screw nut component on running shaft.
Background technique
When running shaft adopts locking nut locking axial workpiece, because axle rotation and axial workpiece are subject to impact load, usually cause locking nut loosening, even employing locking device, larger load on difference and axle during due to assembling, usually also can cause locking nut loosening, the accident that even axial workpiece is deviate from.
Model utility content
It is a kind of for the anti-loosen screw nut component on running shaft that the purpose of this utility model is to provide, and this anti-loosen screw nut component has solved easily loosening technical problem of running shaft upper locking nut, and simple in structure, using effect is splendid.
For achieving the above object, the technical solution adopted in the utility model is as follows:
For the anti-loosen screw nut component on running shaft, described anti-loosen screw nut component comprises binding thread 1, locking screw 2, tightening nut 3, locking nut 4, and described binding thread 1 and locking screw 2 are successively set on running shaft along running shaft ecto-entad; The rotation direction of described binding thread 1 and locking screw 2 is contrary, and the external diameter of locking screw 2 is greater than the external diameter of binding thread 1; The internal thread length of described tightening nut 3 is greater than the length of binding thread 1.
Binding thread in the utility model, locking screw can be for the various screw threads of GB, such as V thread screw or trapezoidal thread etc.
The standard nut of described tightening nut 3 for matching with binding thread.
The standard nut of described locking nut 4 for matching with locking screw.
An anti-loose method based on above-mentioned anti-loosen screw nut component, described method comprises the steps:
1) on locking screw 2, screw locking nut 4, locked the component on running shaft;
2) on binding thread 1, screw tightening nut 3, make together with tightening nut 3 abuts against with locking nut 4.
In the utility model locking nut rotate to tightening nut together with time, locking nut is to axial force of tightening nut, direction is pointed to tightening nut, tightening nut is to axial force of locking nut simultaneously, direction is pointed to locking nut.Locking nut internal thread (side) is under the effect of axial force, tightly lean against locking screw (side), making has larger frictional force between locking nut screw thread and locking screw, this frictional force stops the relative screw thread rotation trend of nut, also has this kind of effect simultaneously and between tightening nut binding thread.
During running shaft rotation of the present utility model, can make tightening nut and locking nut have relative rotation trend, the oriented inner rotary trend of locking nut, the oriented inward turning of tightening nut transfers toward gesture, two nuts are more tightly close together, between locking nut and binding thread, active force is larger, and between nut and screw thread, frictional force is larger, and anti-loosing effect is better.
The utility model has solved the locking problem of running shaft locking nut, and special in the larger running shaft type component of impulsive load, using effect is better, and this apparatus structure is simple, using effect is splendid, applies very extensive.
Accompanying drawing explanation
Fig. 1 is that the utility model is for the structural representation of the anti-loosen screw nut component on running shaft;
Wherein, 1, binding thread; 2, locking screw; 3, tightening nut; 4, locking nut.
Embodiment
With the drawings and specific embodiments, the utility model is described in further detail below.
As shown in Figure 1, a kind of for the anti-loosen screw nut component on running shaft, described anti-loosen screw nut component comprises binding thread 1, locking screw 2, tightening nut 3, locking nut 4, and described binding thread 1 and locking screw 2 are successively set on running shaft along running shaft ecto-entad; The rotation direction of described binding thread 1 and locking screw 2 is contrary, and the external diameter of locking screw 2 is greater than the external diameter of binding thread 1; The internal thread length of described tightening nut 3 is greater than the length of binding thread 1.
Described locking screw and binding thread are V thread screw.
Described locking nut and the tightening nut standard nut for matching with locking screw and binding thread.
Wherein, 3 millimeters of locking screw and locking nut M100 millimeter *, 60 millimeters of locking screw length, 90 millimeters of locking nut thickness; 3 millimeters of binding thread and tightening nut M90 millimeter *, 40 millimeters of binding thread length, 30 millimeters of tightening nut thickness.
An anti-loose method based on above-mentioned anti-loosen screw nut component, described method comprises the steps:
1) on locking screw 2, screw locking nut 4, locked the component on running shaft;
2) on binding thread 1, screw tightening nut 3, make together with tightening nut 3 abuts against with locking nut 4.
It should be noted that, locking screw and binding thread are V thread screw in the present embodiment, but in other embodiments, the type of screw thread can change according to need of production, as are trapezoidal thread etc.
It should be noted last that, above embodiment is only unrestricted in order to the technical solution of the utility model to be described.Although the utility model is had been described in detail with reference to embodiment, will be understood by those skilled in the art that, the technical solution of the utility model is modified or is equal to replacement, do not depart from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
