Description

The solid lock nut of never becoming loose

Technical field

" the solid lock nut of never becoming loose " patent of invention be it is a it is novel by nut firmly solid lock on screw rod it is permanent not The solid lock technology loosened again, right-angled intersection power type solid lock principle is utilized in it, has nut tight with left and right strength up and down Gu achieving the purpose that nut no longer loosens in prolonged vibration, because any one acts on the shake on fixed nut Power (wave) is all being effect back and forth in straight line at that moment, once add lateral locking to it, just to giving it again A mortise pin (or keeper) is added, it is difficult to loosen again, to achieve the purpose that solid lock steady in a long-term, just as we give A lock is the same on nut, so, we are its " solid lock nut ".It is suitable for industrial production, mechanical equipment, traffic fortune In many fields such as defeated, aerospace, and have three great society advantages: (1) production cost is low；(2) simple process；(3) it is applicable in Field is wide.

Technical background

In China, sciemtifec and technical sphere makes rapid progress today of rapid development, and in industrial machinery, high-speed railway rail, wheel etc. all lacks not Stabilization of the screw to object, lasting fixation；However, most of screws are fixed, can be issued in mechanical long-time vibration Nut loosening gives mechanical equipment, and the running of vehicles etc. brings great hidden danger, and " the solid lock nut of never becoming loose " is exactly base In this premise, invention devise this allow nut firmly solid lock on screw rod, allow it is firm for a long time no longer loosen, reach Industry, the permanent running purpose of the every field such as traffic: I just started to conceive this patent before 10 years, never at Function, since it is considered that it must have three big features: (1) production cost is low；(2) simple process；(3) social suitable application area is wide.

Not long ago, seeing that the never becoming loose nut of Japan occurs on the net, I considers or else to make the best use of time to develop, It may be just at chrysanthemum after rain.

By the effort more than lasting half a year, our China will be belonged to finally " the solid lock nut of never becoming loose " successfully research and develop Out: (1) it has production cost low, may be only the half or so of import Japan never becoming loose nut cost: (2) its work Skill is simple, and almost all ordinary enterprises can produce and process: (3) society suitable application area is wide, due at low cost and simple work Skill determines that its suitable application area socially is more extensive.

Japan " never becoming loose nut " and three big disadvantages: (1) its production technology is very accurate, be known as the whole world all without Method is copied；(2) production cost is excessively high, is 5 times or so of our this patent nut cost；(3) applicable field is very narrow, Due to its production technology precision and feature at high cost, its social scope of application is limited to significantly, can not popularize.

" the never becoming loose solid lock nut " in China emerges, and the fastening history in world's nut field will be rewritten from this, it is also desirable to State Intellectual Property Office is generalized to China's industry, and the every field such as machinery contribute widow's mite for Chinese industrial development, more Wish to be generalized to the whole world to promote the well-being of mankind society.

Summary of the invention

" never becoming loose solid lock nut " is made of tooth nut and set two parts of nut: (1) tooth nut is exactly in nut Upper to design a tooth, tooth inside and outside has silk thread mouth: (2) cover nut, and exactly one for covering the nut on tooth nut Set, nut set are made of upper and lower 2 silk thread mouths of different sizes, a minor thread silk mouth, are used for solid lock screw rod, a centrifugation Round major thread silk mouth reaches right-angled intersection power type curable type purpose by screwing fastening tooth nut and screw rod.

In use, set nut and tooth nut are packaged, tooth nut is under, and set nut is upper, and there are certain between 2 nuts Gap, while being screwed on screw rod, following tooth nut is first fastened, then fasten set nut above, this completes nuts Nut is fastened on screw rod simultaneously up and down in this way, forms right-angled intersection power type solid lock, just reached screw by solid lock screw rod The purpose that fastening no longer loosens for a long time.

Principle: on the object fixed, the external shaking force (wave) of any one is in active force at that moment All show off rectilinear direction to act on back and forth, if we are fixed with right-angled intersection power type, is equivalent to laterally go up a lock to it, jail Jail has been locked in that position, and the deviation of screw position no longer occurs, that is to say, that nut is once be used for right-angled intersection power type Solid lock, it is by permanent solid lock on screw rod, because at any time, any environment all will not there are two different directions simultaneously Active force at that moment simultaneously act on the nut being fixed on object, if there are two active force simultaneously shake, Substantially equidirectional active force can only increase the dynamics of this direction active force, and the active force of substantially opposite direction can only reduce this The dynamics in one direction, the reason is that because it and screw rod are fixed on object together: for example, the cart on a track, You push away it from positive direction and will move ahead, you push away it from side positive direction, still can move ahead by orbital direction: if you from opposite direction or Direction of tossing about pushes away it, will reduce the thrust of positive direction, that is, the power of positive direction receives resistance.

Detailed description of the invention

Fig. 1, right side view: design has a tooth on tooth nut, and the inside and outside of tooth is all with silk thread mouth, and set nut is Be made of upper and lower two inner ring silk thread mouths: being small silk mouth above, for solid lock in screw rod, big sealing plug below be one from Heart circle, is fastened on screw rod for entangling to screw the thread of tooth nut: the purpose of the eccentric circle on set nut, due to eccentric position It sets, the thread on tooth nut can be entangled, when screwing, since eccentric circle position is deviateed, when the more stubborn set nut the tighter, Tooth nut is increasing by fastening force of the thread on screw rod, achievees the purpose that solid lock.
