No matter how severe the vibration is, the constant elasticity is kept. The self-locking is reliably realized. The reusability is good and the practicability is strong.
Description
Technical field
The utility model relates to a kind of shock-proof check self-locking fastener, and more particularly, the utility model relates to a kind of shock-proof check self-locking thread fastening piece.In particular for communication (letter), electron trade as regulate, the shock-proof check Self-locking screw of tuning usefulness.
Background technique
In the prior art, for solve be hit, threaded fastener connected the locking mode that three kinds of working principles have been adopted in possible getting loose automatically when vibration or varying load and temperature variation were big: utilize frictional force locking; It is locking to utilize mechanical component directly to pin; The kinematic relation of destroying screw pair is locking.Anti-loose method commonly used has friction locking, comprise, to jacking nut, spring washer, self-locking nut, to jacking nut is that pairs of anti-loose nut is to use two nuts on screw rod, eliminates screw backlash between nut and screw rod by the pretightening force between two nuts, increases frictional force between nut and the screw rod to reach certain locking purpose.After two nuts are tightened the top, make the pressure that added all the time between screw thread and the effect of frictional force of screwing.When work loads had change, this frictional force still existed, and the method is when violent or service time is long in vibration, and two nuts can become flexible the disappearance that causes pretightening force and not have locking effect, can not eradicate the nut loosening problem under long-term vibration operating conditions; Moreover can not be used for to use the occasion of nut; The use of two other nut also causes the increase of cost.Be only applicable to steadily, the connection of low speed and heavy duty.
Spring washer is that the back cushion circle flattens and the elastic reaction that produces makes to screw between screw thread and compresses.Simultaneously the tip of the packing ring angle supporting surface that props up nut and coupled also has locking effect.Simple in structure, locking convenience, but because the elastic force inequality of packing ring, under the operating conditions of impacting, vibrating, its anti-loosing effect is relatively poor, can't be used for using the structure of packing ring, generally is used for the connection of of such little moment.
Self-locking nut is radially to close up after nut one end face is made non-circular closing in or cracked.Behind nut screwing clamping, the closing in spreading utilizes the elastic force that closes up to make to screw between screw thread and compresses.Simple in structure, locking reliable, can repeatedly install and remove and do not reduce anti-loosening property.Be applicable to more important connection, but can't be used for using the structure of nut.
Machinery is locking to comprise that mainly cotter pin and slotted nut are locking, lock washer, and the series connection steel wire is locking.Behind the locking flute profile nut screwing clamping of cotter pin and slotted nut cotter pin is penetrated in the groove of bolt tail aperture and nut.Cotter pin and slotted nut are locking, cotter pin are penetrated in the groove of bolt tail aperture and nut after slotted nut is tightened.And the cotter pin afterbody broken into two with one's hands with the nut side be adjacent to.Also available plain nut replaces slotted nut, but needs to join draw-bore again behind the fastening nut.Be applicable to greater impact, the connection in the speed governing machinery of vibration.
Lock washer is that monaural or lock washer with double ears are adjacent to nut and coupled 's side bending respectively, promptly nut can be pinned behind the nut screwing clamping.If when two bolts need duplex locking, can adopt the duplex lock washer, two nuts are braked mutually.Simple in structure, easy to use, locking reliable.
The steel wire of connecting is locking to be to penetrate in the hole of each screw head with mild steel wire, and each screw is together in series, and it is braked mutually, must be noted that the direction that penetrates of steel wire during use.Be applicable to that set screws connects, locking reliable, but mounting or dismounting inconvenience.
In order to solve nut anti-looseness, the U.S. executes and must firm Co., Ltd set up the Shanghai Detroit Precision Fastener Co., Ltd that specializes in loose-proof self-lock nut in Shanghai.Executing firm nut to be a kind of variable-tooth type lock nut, and dividing in the tooth bottom of nut has 30 ° of wedge shape inclined-planes, when bolt and nut meshes, the bolt cusp is along with the screw thread rotation line, all withstand on 30 ° of inclined-planes of nut, form one spiral from locking wire, make its self-locking.As everyone knows, be threaded normally is to lean on the middle footpath of screw thread to realize, this increase screw thread frictional force method is by the screw thread reducing, changes the tooth form angle, sacrifices the intensity of tooth form root, and screw thread is clamp-oned screw pair by force, not only reduced the concatenation ability of normal helical thread portion, strengthened the tooth bottom stress and concentrated, intensity further is lowered, and causes the wearing and tearing in footpath, screw thread top easily and not wear-resisting, fatigue ruption takes place under frequent sharp pounding environment easily, has reduced locking reliability.And the lock nut manufacture difficulty of the kinematic relation of this bad screw pair of breaking is high, and manufacture cost is big.
In sum, present threaded fastener all is that the axial pre tightening force that produces when tightening is realized.This pretightening force reduces will cause becoming flexible gradually in strenuous vibration.The form of bolt looseness has three kinds of forms such as horizontal transposition, transverse translation and axial strain, and these loosening forms all can cause between screw or the displacement between nut and supporting surface---occur from loose phenomenon.Loosing Prevention Technology was all once done excessive quantity research both at home and abroad, had adopted multiple way, for example: nylon self-locking nut, metal self-locking nut, spring washer, inside and outside spring washer and anaerobic adhesive locking etc.The shock-proof check mode that the prior art fastening piece adopts all will be separately advantage and application occasion separately, also there is the deficiency of different running environment in the while.Particularly under the complex vibration environment, the conduct adjusting that communication (letter), electron trade adopted in the past, tuning plain screw, when reaching work in transit, cause screw loosening because of vibration and temperature variation easily, cause that screw departs from the working position, cause the drift of electrical signal, thereby make the equipment can't proper functioning, even damage.
