Many jumboes are largely connected in design for convenience of dismantling and repairing using bolt in mechanical industry industry
Connect.Bolt and nut why can play a part of connection fastening, be bolts and nuts screw thread between and nut with set
There is frictional force between standby part can prevent nut loosening.People reach often through the coefficient of friction for increasing bolt and nut
To locking purpose.Some check bolt nut products (such as sawtooth nut, nylon nut, double toothed pads etc.) are in structure design
Upper increase coefficient of friction, its torque coefficient is very big, is tightened in the case of equal moment of torsion, due to the ratio that coefficient of friction error is accounted for
Greatly, so the pretightning force error of bolt is just very big, the pretightning force deviation of same part difference bolt is very big, and pretightning force is uneven then
The connection reliability of equipment can be caused to decline；(such as lock glue, perforate latch, electric welding, breaks the methods such as ring screw thread and prevents for some producers
Pine) increase coefficient of friction after bolt is tightened, cause then be checked if any loosening after equipment operation in bolt and nut and obtain
Know, cannot also carry out the operation that loose bolts pretightning force is supplied.In a word, it is accurate if necessary to bolt and nut pretightning force, Ren Mentong

Need the method using coefficient of friction is improved and reduce torque coefficient.Bolt and nut pretightning force is accurately required and locking requirement
It is forever conflict body, in the centuries that there is development of modern industry, up to the present nobody proposes real feasible solution
Certainly scheme.
Current most of bolt connections are all fastened using moment of torsion tightening method.The moment of torsion method of tightening is revolved using torque tool
Turn nut, by the relative displacement between nut and the screw thread of bolt, makes bolt be forced stretching and produces elastic deformation, so that spiral shell
Bolt produces the pretightning force of resilience.Because positioned at nut and part base surface (such as flange or equipment sheet of same position diverse location
Body) between coefficient of friction it is uneven, acting on identical moment of torsion on nut can not obtain identical bolt elastic deformation amount, turn round
Square is converted into bolt pretightening and is also just not quite similar；During calibrated wrench method tightens nut, needed while action torque is applied
Apply a reaction torque, this reaction force can be typically acted on the fulcrum of bolt annex, cause bolt deflection, according to
Leaning against causes unbalance loading on the side of screwed hole；In the case where nut is tightened, the moment of torsion of nut can be delivered on bolt, bolt
Another side makes bolt that transfer will not occur by head of screw coefficient of friction or support spanner back strength, so results in bolt and produces one
Individual overall torsional shear stress.
In actual moving process, the operating mode such as vibration, the temperature difference, pressure difference, pretightning force is inaccurate, it is whole to exist to exist which
Body torsional shear stress or the bolted bolt and nut of the less mechanical equipment component of coefficient of friction loosen.Bolt pretightening without
Method remains requirement during original plant equipment industrial design, it may occur that large scale equipment collapses, petrochemical equipment leakage
The serious work safety accident such as gas, oil leak.In order to improve the safety in operation of equipment, the method being usually taken is regular for enterprise
The mechanical engineer of (weekly, three months, half a year or 1 year) group specialty takes professional bolt tightening device, and (bolt torque is tightened
Equipment), associated bolt nut is checked one by one, bolt looseness regular inspection is referred to as in industry.In the work of equipment bolt regular inspection,
Check whether bolt is loosened, it is necessary to spend engineer's substantial amounts of time.Safety during in order to ensure engineer's operation, in equipment spiral shell
During anchoring inspection work, equipment is required out of service, and this causes damage the yield of the equipment of reduction.Enterprise is annual in tools for bolts ' pretension
Power is inspected periodically with maintenance work, and artificial, purchase or lease check the equipment whether bolt loosen and caused by shutdown
Yield reduce etc. aspect it is costly.

A taper tolerance more than 0 degree is produced after tightening, the threaded collar is embedded in the packing ring and the work to carve type loop type
Make in the middle of bolt, play the locking effect of bolt and nut connection.
Under the moment of torsion effect that moment of torsion tightens method, bolt and nut produces relative movement to slotted nut, and bolt produces elasticity to become
Shape, when bolt is in the case of stress, the associated components of packing ring skidproof bottom end-tooth and equipment (flange or other need to be connected
Part) surface of base engagement, so as not to produce relative rotation, the other end of smooth surface of packing ring and the smooth bottom of nut
Face contacts, and makes nut relatively small with the coefficient of friction of packing ring and uniform, and then bolt is obtained accurate pretightning force；Due to pad
Circle skidproof bottom end-tooth is engaged and will not turned with equipment associated components (part that flange or race ring or other needs are connected)
It is dynamic, and threaded collar is coordinated by interior external splines and packing ring, so threaded collar also will not be rotated mutually, can only be along flower in packing ring
Key is slided up and down.Bolt is coordinated by screw thread with threaded collar, when bolt is by nut screwing clamping, because threaded collar will not be rotated, and spiral shell
Bolt is forced to rotate, and can only pull up displacement by nut, so bolt will not produce entirety during being tightened
Twisting stress；When the taper tolerance between nut screwing clamping rear thread ring and packing ring makes threaded collar that pad is embedded in the form of carving type ring
Between circle and bolt, playing effectively prevents the connection between work bolts and nuts from loosening.
