Abstract
The utility model discloses a self-locking nut with an aim to solve the problem that limiting, positioning and locking methods of axial parts in the prior art are poor in locking effect and high in production cost. The self-locking nut comprises a nut body, the inner circular threaded surface of the nut body is provided with two threaded key grooves, threaded keys matched with the threaded key grooves are arranged in the threaded key grooves, threads on the threaded keys are same with the thread on the nut body, a central angle formed between the two threaded keys is smaller than 18 degrees, the nut body is provided with fastening screw holes corresponding to the threaded keys, and the threaded keys are locked by fastening screws. The self-locking nut is efficiency, safe and reliable in locking, material saving and low in production cost.
Description
Technical field
The utility model relates to a kind of Self-lock nut for axial limit, positioning and locking.
Background technique
Common method used when parts on shaft needs axial limiting, location, locking has: the first is to lock with wire circlip or circlip for shaft, and still, when axially loaded is larger, this mode spacing, that locate or lock just can lose efficacy; The second is to lock with double nut, and while adopting double nut locking, axial dimension lengthens, and has increased raw material, and then has improved cost of production; The third is when axial dimension is restricted, selects with the locking nut of jump ring or nut, to join check washer or lock nut and add steel wire and lock, yet while adopting in this way, if one of them lost efficacy, can cause that axial limiting, location and locking lost efficacy; The 4th kind is on some lathe horizontal axis, to adopt a screw thread briquetting or threadless briquetting and nut fit applications to lock, but while encountering large journal axle or vertical shaft, this structure is just inapplicable.
Model utility content
For the problems referred to above, that the utility model provides a kind of and saves material, reduces production costs is efficient, safety, Self-lock nut reliably.
For achieving the above object, the utility model Self-lock nut, comprise nut body, inner circle flank of thread at described nut body is provided with two screw thread keyways, in described screw thread keyway, be provided with the screw thread key suitable with described screw thread keyway, screw thread on described screw thread key is consistent with the screw thread of described nut body, the central angle forming between two described screw thread keys is less than 180 °, on described nut body corresponding described in each screw thread key be provided with fastening screw, described screw thread key is locked by fastening screw trip bolt.
Preferably, described in each, screw thread key is locked by two described fastening screw trip bolts, and wherein the first fastening screw trip bolt is locked described screw thread key and the suitable male thread of nut body, and the second fastening screw trip bolt is locked the first fastening screw trip bolt.
Particularly, described screw thread key and vertical setting of described the first fastening screw trip bolt.
Particularly, the axis of described fastening screw is through the axle center of described nut body.
The utility model Self-lock nut, by two screw thread keyways are set on described nut body, the screw thread key suitable with described screw thread keyway is set in described screw thread keyway, and the screw thread on described screw thread key is consistent with the screw thread of described nut body, described screw thread key is carried out to axial limiting, location and locking by fastening screw trip bolt.Compared with prior art, the utility model Self-lock nut, simple in structure, easy to operate, be not subject to anyly axially and the restriction of radial dimension can easily realize self-locking, self-lock ability is efficient, safety, reliably, can effectively save raw material, and then reduce production costs simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model Self-lock nut;
Fig. 2 is the work schematic diagram of the utility model Self-lock nut.
Embodiment
Below in conjunction with Figure of description, the utility model is further described.
As shown in Figure 1-2, the utility model Self-lock nut, comprise nut body 1, inner circle flank of thread at described nut body 1 is provided with two screw thread keyways, described in each, in screw thread keyway, be provided with the screw thread key 2 suitable with described screw thread keyway, screw thread on described screw thread key 2 is consistent with the screw thread of described nut body 1, the central angle forming between two described screw thread keys is less than 180 °, on described nut body 1 corresponding described in each screw thread key 2 be provided with fastening screw, the axis of described fastening screw is through the axle center of described nut body 1, described screw thread key 2 is locked by fastening screw trip bolt.
The utility model Self-lock nut, described in each, screw thread key 2 is locked by two fastening screw trip bolts, i.e. the first fastening screw trip bolt 3 and the second fastening screw trip bolt 4, wherein the suitable male thread 5 of 3 pairs of described screw thread keys 2 of the first fastening screw trip bolt and nut body 1 is locked, and second 4 pairs of fastening screw trip bolts the first fastening screw trip bolt 3 is locked.
The utility model Self-lock nut, described screw thread key 2 and the vertical setting of described the first fastening screw trip bolt 3, can make like this 3 pairs of vertical application of forces of described screw thread key 2 of described the first fastening screw trip bolt, so that described fastening screw trip bolt exerts pressure to described screw thread key 2 better, thereby by described Self-lock nut locked being fixed on described male thread 5 firmly.
Be illustrated in figure 2 the utility model Self-lock nut work schematic diagram.When the described Self-lock nut of assembling, first two described screw thread keys 2 are respectively installed in two described screw thread keyways, described nut body 1 is rotated in place together with described screw thread key 2, with described the first fastening screw trip bolt 3, described screw thread key 2 is tightly locked with described male thread 5, with the second fastening screw trip bolt 4, described the first screw 3 is firmly locked afterwards, while noting assembling, according to former order separately, along hand of spiral, be rotatably fixed on described male thread 5 and limit, locate.Like this under the acting in conjunction of two fastening screw trip bolts, described screw thread key 2 tightly fits together with described male thread 5, no matter be subject to great axial force, thereby described Self-lock nut all cannot be realized rotation and produce axial displacement, realize the most efficient, safety, the axial object of limit, positioning and locking reliably.
The utility model Self-lock nut, the screw thread of described nut body is applicable to standard or the odd-pitch screw of various series, do not need special, simple in structure, easy to operate, be not subject to any axially or the restriction of radial dimension, can realize easily self-locking, and self-lock ability safety, reliable, has application prospect very widely.
Above; it is only preferred embodiment of the present utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim was defined.
