Abstract
The utility model discloses a kind of set screw nut, comprise nut main body (1), nut main body (1) in hollow cylinder shape and in establish internal thread, nut main body one end is provided with stopper (2), stopper is also in hollow cylinder shape, stopper external diameter is greater than nut main body external diameter, sphere boss (3) is provided with stopper adjacent, aperture, sphere boss openings place and nut main body internal diameter size match, and sphere boss (3) matches with the chamfering of hub stud holes.The utility model structure is simple, and installing/dismounting is all very convenient, can significantly improve nut anti-looseness performance.
Description
Technical field
The utility model relates to a kind of set screw nut.
Background technique
For the ease of the dismounting of tire, the diameter of bolt hole on wheel hub is greater than the external diameter of bolt usually, has comparatively Multiple level after installation.Wheel hub and the wheel in gap are installed, center line both it is not on the same axis, wheel is easily caused to produce irregular running when walking, particularly when pitch and brake impact, wheel hub easily produces great shearing force, the working life of tire bolt can be shortened like this, by causing the expansion of wheel hub upper bolt hole, even destroy wheel hub.
Model utility content
The technical problems to be solved in the utility model is, for the above-mentioned defect of prior art, provides a kind of installation, dismounting easily, is conducive to the set screw nut protecting wheel hub.
The utility model adopts following technological scheme: a kind of set screw nut, comprise nut main body (1), nut main body (1) in hollow cylinder shape and in establish internal thread, nut main body one end is provided with stopper (2), stopper is also in hollow cylinder shape, stopper external diameter is greater than nut main body external diameter, sphere boss (3) is provided with stopper adjacent, aperture, sphere boss openings place and nut main body internal diameter size match, and sphere boss (3) matches with the chamfering of hub stud holes.
The nut main body (1) of above-mentioned model utility is in regular hexagon column.
Stopper (2) exterior contour of above-mentioned model utility is rounded.
The stopper (2) of above-mentioned model utility is provided with ring-type ear body (4) near nut main body side.
The utility model structure is simple, and installing/dismounting is all very convenient, can obviously protect wheel hub not to be damaged, be particularly suitable for the occasion of high vibration or dynamic load.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is model utility structural representation;
Fig. 2 is the worm's eye view of Fig. 1.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1 and Figure 2, a kind of set screw nut, comprise nut main body 1, nut main body 1 in hollow cylinder shape and in establish internal thread, nut main body one end is provided with stopper 2, and stopper is also in hollow cylinder shape, stopper external diameter is greater than nut main body external diameter, be provided with sphere boss 3 with stopper adjacent, aperture, sphere boss openings place and nut main body internal diameter size match, and sphere boss 3 matches with the chamfering of hub stud holes.Nut main body 1 is usually in regular hexagon column, and stopper 2 exterior contour is rounded, plays reinforcement fixation by clamping wheel hub, and stopper 2 can establish ring-type ear body 4 near nut main body side, and ear body plays the effect of support stopper.
The sphere boss of the utility model set screw nut coordinates with the chamfering of hub stud holes, after set screw nut locking tire, the sphere boss of set screw nut and wheel hub produce an axial force and shear bearing capacity, axial force is that bolt connection increases coupling mechanism force, radial shear power carries the shearing force that tire produces when pitch and brake impact, tire keeps same axis to operate in walking always, greatly can improve the stability that tire is in operation.Because tire tire when pitch and brake impact does not produce skew, bolt does not also just produce destruction to the bolt hole of wheel hub, thus protects wheel hub.
In a word, the utility model structure is simple, and installing/dismounting is all very convenient, can obviously protect wheel hub not to be damaged simultaneously, be applicable to the occasion being applied to high vibration or dynamic load.
Claims (4)
1. a set screw nut, comprise nut main body (1), it is characterized in that: nut main body (1) in hollow cylinder shape and in establish internal thread, nut main body one end is provided with stopper (2), stopper is also in hollow cylinder shape, stopper external diameter is greater than nut main body external diameter, sphere boss (3) is provided with stopper adjacent, aperture, sphere boss openings place and nut main body internal diameter size match, and sphere boss (3) matches with the chamfering of hub stud holes.
