Abstract
The invention discloses a deformed-face grooved locknut. The deformed-face grooved locknut comprises a jam nut and a grooved nut, wherein the grooved nut is provided with a groove; the non-bearing face of the grooved nut comprises a compressing face; a deformed face is arranged close to the compressing face in an extending manner; the compressing face is located at the upper end of the groove mouth of the groove. During installation, the bearing surface of the grooved nut is in contact with a clamped workpiece, the non-bearing face of the grooved nut is screwed, tightened and compressed by the jam nut, the compressing face of the grooved nut bears pressure to compress the groove of the grooved nut, and locking is completed. The deformed-face grooved locknut has a better anti-looseness effect. Owing to the down-pressing function of the jam nut, the friction moment between the compressing part and the nut can be well controlled. The deformed-face grooved locknut can provide a stable and reliable anti-looseness moment, is simple in process, utilizes a mature grooved nut processing technology, and is relatively low in cost.
Description
Technical field
The invention belongs to machanical fastener field, particularly, the present invention relates to a kind of antarafacial and cut groove lock nut.
Background technique
After plain bolt and nut are installed, keep relatively fixing by the principle of " self-locking " and do not loosen.But due to the impact of mechanical equipment vibration etc., on nut and bolt, self-lock force may be decayed or disappear.
Nut anti-looseness have a large class to be called friction is locking, its major way is the friction torque by increasing between bolts and nuts, improves the moment that needs when loosening thus plays locking effect.
Like closer with us in the market, scheme mainly contains two kinds:
Double nut, by two nut anti-looseness successively tightened, its cardinal principle has remained pretightening force and friction torque, when change appears in work loads screwing on screw thread after two nut, this friction torque exists all the time, thus two nuts can be remained on bolt.Although nut can be fixed on bolt by double nut scheme, its fixing pretightening force is less, there will be loosening when vibrating violent.
HRADLOCK assembled nut, the program processes an eccentric conical surface on nut, when upper cap nut is screwed into lower nut, eccentric conical surface is squeezed, thus make the thread hold-down bolt of conical surface inside, increase the friction torque between lower nut and bolt, improve anti-loose ability.HARDLOCK nut anti-looseness ability is better, but complex-shaped, and cost is higher, and upper lower nut all needs to adopt special purpose machine tool processing.
Summary of the invention
The invention provides a kind of antarafacial for solving the problem and cut groove lock nut.By introducing extra locking mechanism and mounting type, make to keep locking torque between screw bolt and nut, thus the effect locking to antivibration
For reaching above-mentioned technique effect, technological scheme of the present invention is:
A kind of antarafacial cuts groove lock nut, comprises and cuts groove nut, cuts groove nut and is provided with and cuts groove, described in cut groove nut non-bearing face comprise a seal face, next-door neighbour's seal face extends and is provided with a deformation plance, and wherein seal face is positioned at the upper end of the notch cutting groove; During installation, cut the supporting plane of groove nut and clamped absorption surface, screw to compress cut the seal face of groove nut by locking nut, what the seal face cutting groove nut bore that pressure compaction cuts groove nut cuts groove, completes locking.
Optimal technical scheme provided by the invention is, described deformation plance is inclined-plane, and deformation plance is downward-sloping away from notch direction from seal face.The inclination of described deformation plance is 5 °-30 °.
Or described deformation plance is curved surface, and deformation plance is downward-sloping away from notch direction from seal face.
In addition, described deformation plance is the step plane lower than seal face.
In above-mentioned technological scheme, the position, boundary of described deformation plance and seal face is positioned at the notch side of cutting groove nut.
The present invention has following beneficial effect:
1. better anti-loosing effect.Due to the suppressing action of locking nut, can be good at the friction torque controlling pressing section and bolt, lock nut of the present invention can provide reliable and stable locking moment.
2. technique is simple.What present invention utilizes maturation cuts groove nut processing technology, and cost is lower.

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
Fig. 1 is the plan view that antarafacial of the present invention cuts groove nut; Fig. 2 is the plan view of Fig. 1; Fig. 3 is the stereogram that antarafacial of the present invention cuts groove nut; With reference to accompanying drawing 1, Fig. 2 and Fig. 3, a kind of antarafacial of the present invention cuts groove lock nut, comprise and cut groove nut 2, cut groove nut 2 to be provided with and to cut groove 21, the non-bearing face (i.e. upper-end surface) of cutting groove nut 2 comprises a seal face 30, the extension of next-door neighbour's seal face 30 is provided with a deformation plance 31, and deformation plance 31 is inclined-plane, and deformation plance 31 is downward-sloping away from notch 22 direction from seal face 30.The inclination θ of deformation plance 31 is 5 °-30 °, and the present embodiment adopts 15 °.Wherein, seal face 30 is positioned at the upper end of the notch 22 cutting groove 21; Deformation plance 31 is positioned at notch 22 side of cutting groove nut 2 with the position, boundary of seal face 30.
Fig. 4 is installment state schematic diagram of the present invention; Fig. 5 is installation view of the present invention; During installation, first tighten according to the moment of regulation and cut groove nut 2, ensure that the deformation plance 31 cutting groove nut 2 is positioned at top, supporting plane is in below, then locking thin nut 1(is tightened as shown in Figure 4 by the moment of regulation), locking nut 1 is pressed on and cuts on the seal face 30 of groove nut 2, is screwed the seal face 30 compressing and cut groove nut 2 by locking nut 1, what the seal face 30 cutting groove nut 2 bore that pressure compaction cuts groove nut 2 cuts groove 21, completes locking (as shown in Figure 5).
When locking thin nut 1 and constantly tightening, axial pressing force is produced to the compression position of cutting groove nut 2, the screw thread of this part is pressed on the corresponding screw thread of construction bolt, becomes drive fit between the two, considerably increase bolt and the frictional force of cutting on groove nut 2 tooth.
When mounted workpiece is subject to oscillating load, vibration can be passed to cuts on groove nut 2, due to the friction torque that pressing section increases, cuts the locking moment that groove nut 2 can provide larger, greatly improves anti-loosening ability.
Through test, the program can provide good anti-loosening property.
Fig. 6 is another one embodiment provided by the invention, and deformation plance 31 is curved surface, and deformation plance 31 is downward-sloping away from notch 22 direction from seal face 30.Specifically be installed on previous embodiment identical, repeat no more herein.
As shown in Figure 7, deformation plance 31 can also be adopted as the form of the step plane lower than seal face 30.
The explanation of above example just understands core concept of the present invention for helping; Meanwhile, for one of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
