Description
Technical field
The utility model relates to a kind of nut more particularly to a kind of screw rods for being adjustable aperture, nut anti-looseness combination unit.
Background technique
Existing screw rod, nut, ordinary circumstance are batch productions, will not be directed to each piece of screw rod actual size, then special
The nut exactly matched therewith, so all there is more or less error, they are being screwed up in practical manufacture, use process
When, there can be gap between screw thread, be that 100% cannot coincide, can only be that part coincide.Engagement between screw thread mainly relies on
Nut tightens the reaction force of (axial direction) longitudinal caused by fixture, makes to generate press effect between screw thread, loading characteristic:
First is that there are biggish gaps between screw rod and nut；Second is that unbalance stress, is concentrated mainly on the 1st, 2 screw threads, easily office
Portion's deformation, so that whole be gradually damaged；Third is that the forced area of screw thread is limited, the downside of upper track screw thread is often confined to under
Between the upper side of road screw thread；Fourth is that the stubborn power that nut can bear is limited, usually in order to promote frictional resistance with locking, twist
Tension directly causes thread damage, the above a variety of factors, and the engagement of screw thread is difficult securely to arrive never becoming loose.
But in the modern life, production, there are many equipment, such as train, generator, engine, vibration hammer, at work
Huge vibration can be produced, fixture, screw rod can make rapidly irregular longitudinally, laterally relative displacement between nut, produce huge
Big destructive power destroys the screw thread among engagement step by step, finally causes to loosen, to make not loosen, it is necessary to increase resistance when loosening
Power, to prevent thread looseness.
In order to locking, domestic and abroad scientific and technical personnel did a large amount of practices, but were confined in the improvement of nut, for example, now in
" the Hard Lock of the never becoming loose of Japanese Hard Lock Kogyo K. Co. that the country such as state, Japan or even Germany generallys use
Nut ".It is also only the principle by chock, solves the problems, such as easy loosening using 2 eccentric nuts, but for screw thread unevenness
Even stress problem (chock circumferential pressure is especially big), still not can effectively solve, and Reusability be easy to cause local damage, and raw
Production. art is miscellaneous multiple, although structure very simple, production difficulty is very big, many enterprises's " object is hoped to heave a sigh ".It is existing locking to solve
The problem of technology, the utility model provides a kind of nut for being adjustable aperture, the anti-pine combination of screw rod, not only to nut
Be transformed, completely new innovation also proposed to screw rod and fixture, first is that improve screw thread tightness degree, increase stress and
Forced area significantly increases frictional force when loosening, second is that making screw thread more evenly stress, breaks caused by effective decomposition vibration
Bad power, third is that screw diameter is not equal big above and below, it is up big and down small, stop nut to be loosened from bottom to top, fourth is that being arranged in screw rod
Partial several concane gaps can effectively stop relative displacement between screw thread, prevent nut from curling up loosening, and five are locked out fixation
Object, screw rod, nut, lateral displacement when reducing vibration between them, mitigate the destructive power of vibration, sixth is that production from source
Equipment, technique are of less demanding, and production is simple.
