Description
Technical field
The present invention relates to a kind of fastener constructions, the most individually controllable elastic cover stop nut.
Background technology
It is one conventional in mechanical connection manner that bolt connects, and has and can repeat dismounting, it is simple to the advantage of maintenance.But bolt connects also an obvious shortcoming, it is simply that easily loosen.Causing bolt looseness easily with respect to rotation between nut and screw rod, especially vibration can cause bolt looseness.In order to stop bolt looseness, existing frequently with the method for solution problem have a few class.The first kind is to utilize machinery body to block to prevent bolt looseness.Block mainly by mechanical body between nut and screw rod in bolt and prevent bolt looseness.Equations of The Second Kind is to utilize various frictional force to prevent bolt looseness.Including the friction utilized between bolt and connected piece to prevent bolt looseness and to utilize in bolt the friction between nut and screw rod to prevent bolt looseness.
Utilizing the friction between bolt and connected piece to the method preventing bolt looseness, commercially available bolt has a lot of such example.The contact surface being included in bolt and connected piece arranges ripple increase this kind of method of friction.This method has a feature, it is simply that affect connected body, is affected by connected body again simultaneously.This kind of bolt must be to be fastenedly connected to the contact relation of connected body, and pine not at all can be anti-loosening, and being located by connecting more can not be anti-loosening.Connected body is not necessarily required to this fastening, it is not necessary to can bear this fastening and additional friction.Meanwhile, the moment of torsion determined needed for bolted fastening is also disturbed by additional friction.And this method can not prevent from vibrating loosening, because great majority vibration directly conducts from connected body of causing well.
Utilizing the friction between nut and screw rod is the method being relatively improved to prevent bolt looseness.Friction produces between nut and screw rod, and the anti-loosening function of bolt will not interfere with connected body, also will not be disturbed by connected body.This kind of method of origin according to friction can be divided into again three kinds:
1, by being parallel to screw rod axle center, screw rod applying tension force is caused friction.Modal, relatively screw on a screw rod with two nuts, two nuts mutually just can produce pair of parallel in the tension force in bolt axle center to extruding pressure, and the frictional force of tension force generation can prevent bolt looseness to a certain extent.The friction that this axial tensile force that what the utility model patent of Patent No. ZL201120036053.0 was intended to construct and utilize is also causes.The most very well, frictional force is little, and the bolt looseness effect causing anti-vibration is limited for the effect of the anti-bolt looseness of the most this method.
2, cause friction by screw rod is applied shearing.Such as utilizing and relatively rotate around the eccentric shaft being parallel to screw thread axle center between two nut parts, cause the screw thread axle center dislocation of two nut parts that translation occurs, nut part is applied with shearing to screw rod.The shearing of screw rod can be designed to very big by this nut part, and corresponding frictional force is very big, and the modular construction producing frictional force is totally independent of connected body, and it is controlled that friction prevents the effect of bolt looseness to be completely independent.The problem of this method is that stop nut difficulty of processing is bigger, and for the bolt of small dimension size, the center displacement amount of this nut is difficult to accurate machining control.
3, cause friction by screw rod is applied chucking power.The utility model patent of Patent No. ZL201220525689.6 is exactly an example, and this patent is to produce chucking power and friction by nut thread reducing.This kind of chucking power and friction can also be produced by arranging flexible rubber ring or flexure strip inside nut.Certain this fixing clamp structure can not be designed with the biggest chucking power and frictional force, otherwise can affect the mounting or dismounting of bolt.ZL201220337786.2 utility model patent is the improvement to this method, its nut part (Rotary-table) in substance form an elastic cover, elastic cover can be become big along with the installation elastic cover (Rotary-table) of nut by (cylinder) extruding to the chucking power of screw rod, and frictional force can also become the biggest.This patent formula major defect be this chucking power be passive generation, the process that elastic cover (Rotary-table) is extruded Bei (cylinder) is uncontrollable.Likely bolt does not also completely arrive at predetermined link position, and the real Tightening moment needed also is not up to, and elastic cover (Rotary-table) is deformed the friction that produces and moment of friction first creates in a large number, and result disturbs the correct fastening of bolt.In this way needing to improve, the process that is extruded making elastic cover is the most independent with the fastening installation process of bolt, makes the frictional force of opposing bolt looseness to be actively controlled.
Summary of the invention
For the problem easily loosened between nut and screw rod in prior art, the present invention proposes the individually controllable elastic cover stop nut that a kind of anti-loosening frictional force can control.
The individually controllable elastic cover stop nut of the present invention, check bolt is cooperatively formed with screw rod, it is characterized in that this stop nut includes the nut part (1) of band elastic cover and independent control parts (2), wherein: the nut part (1) of band elastic cover is internal to be threaded, one end is plain nut, contacting with connected piece, the other end is taper elastic cover, and taper elastic cover edge is longitudinally at least provided with a straight joint；The independent parts (2) that control are set to the conical pipe of nut part (1) the taper elastic cover close contact with band elastic cover, and nut part (1) and independently control parts (2) control relative motion by the screw thread cooperated.
Nut part (1) the taper elastic cover outer surface of described band elastic cover arranges taper thread, cooperates with the independent interior taper thread arranged of parts (2) conical pipe that controls.
Optionally, nut part (1) the taper elastic cover outer surface of described band elastic cover is smooth surface, and independent control arranges plain nut outside parts (2) conical pipe, and the screw thread of plain nut cooperates with screw rod.
On screw rod, when the nut part of the band elastic cover of close contact and independent control parts move toward one another, conical pipe extruding taper elastic cover, the deformation of taper elastic cover can be made to tighten up and to hold screw rod tightly, make to produce between nut and screw rod pressure and frictional force, be possible to prevent bolt looseness；When nut part is separated from each other with the independent control opposing reverse motions of parts, conical pipe unclamps taper elastic cover, taper elastic cover relies on natural resiliency deformation to loosen screw rod, above-mentioned pressure and frictional force in bolt disappear, and this stop nut just can coordinate repeated disassembled and assembled to use with screw rod as plain nut.
