Description
Technical field
The present invention relates to a kind of locking device, in particular, relate to a kind of major diameter axle head left and right sides spin nut locking device.
Background technique
At present, when the end of major diameter axostylus axostyle needs nut to tighten, because axostylus axostyle is a major diameter; So nut is not easy to tighten; And machinery also can to cause nut to produce in the vibrations in when operation loosening, the degradation in the time of can causing mechanical movement, even can lead to a disaster.
For preventing the generation of nut loosening phenomenon, have special-purpose locking nut, but this locking nut should punch simultaneously on axostylus axostyle, nut, after assembling, twine again and tie up iron wire, and can not reuse; Also there is a kind of locking nut to realize, can not reuses equally with encapsulating;
Also have to use and revolve screw thread combination bolt and nut about anti-loosening, this assembling bolt nut be through about revolve screw bolt, reciprocity law power when nut cooperates, reach anti-loosening effect.But two nuts are next anti-loosening through frictional force, because function of friction also can make set screw nut Hui Song, locking effect is not very good; And constantly reciprocity law power can make frictional force constantly change, and pretightening force just is difficult for prediction like this; The major diameter axle head is needed also to be not easy to tighten when locking.Up to the present, a kind of reusable major diameter left and right sides spin nut locking device does not appear on the market as yet.
Summary of the invention
The objective of the invention is well to tighten the end and the easy loosening phenomenon of nut of major diameter axostylus axostyle, and a kind of major diameter axle head left and right sides spin nut locking device is provided to existing nut.
Major diameter axle head of the present invention left and right sides spin nut locking device; Comprise major diameter axostylus axostyle, clamped body and locking device; Revolve screw thread about the end E section of said major diameter axostylus axostyle and F section are provided with, described locking device by set screw nut, stretching screw, push screw open and locking nut is formed, set screw nut is tightened on E section screw thread; Locking nut screws at F section screw thread; Set screw nut and locking nut spacing 0.5mm-20mm, stretching screw be connected and fixed nut and locking nut are pushed screw attachment set screw nut and locking nut open.
The end E section of said major diameter axostylus axostyle is dextrorotation, and the F section is left-handed, and said set screw nut is left-handed following in the dextrorotation, and locking nut is left-handed going up under the dextrorotation.
The end E section of said major diameter axostylus axostyle is left-handed, and the F section is dextrorotation, and said set screw nut is under the left-handed last dextrorotation, and locking nut is left-handed following in the dextrorotation.
Described set screw nut and locking nut spacing 5mm-10mm.
The front end of said stretching screw has screw thread, and the rear end does not have screw thread, and there is screw thread said rear end of pushing screw open; Front end does not have screw thread, 1-3 blind hole of processing on the said set screw nut circumferencial direction, 1-3 interior threaded hole; Blind hole and interior threaded hole intercross arrangement, 1-3 light through hole of processing on the described locking nut circumferencial direction, 1-3 internal thread through hole; Light through hole and internal thread through hole intercross arrangement; The light through hole that the threaded front end of stretching screw passes on the locking nut connects with interior threaded hole on the set screw nut, and the rear end screw thread of pushing screw open screws in the internal thread through hole on locking nut, and front end withstands in the blind hole on the set screw nut.
Beneficial effect of the present invention: (1) simple in structure, be easy to make; (2) practical, can reuse, and can well prevent mechanical shock and the loosening phenomenon that produces; (3) pretightening force is constant, effectively prevents the loosening of nut; (4) avoid mutual friction between nut, prolonged the service time of nut; (5) easy for installation.

Embodiment
Revolve screw thread about the end E section of said major diameter axostylus axostyle 1 and F section are provided with, said E section is dextrorotation, and the F section is left-handed; Said set screw nut 3 in the dextrorotation left-handed down, locking nut 5 be left-handed under the dextrorotation, locking device by set screw nut 3, stretching screw 4, push screw 6 open and locking nut 5 is formed; The front end of said stretching screw 4 has screw thread, and the rear end does not have screw thread, and there is screw thread said rear end of pushing screw 6 open; Front end does not have screw thread, 2 blind holes of processing on said set screw nut 3 circumferencial directions, 2 interior threaded holes; Blind hole and interior threaded hole intercross arrangement, 2 light through holes of processing on described locking nut 5 circumferencial directions, 2 internal thread through hole; The light through hole that light through hole and internal thread through hole intercross arrangement, stretching screw 4 threaded front ends are passed on the locking nut 5 connects with interior threaded hole on the set screw nut 3, and the rear end screw thread of pushing screw 6 open screws in the internal thread through hole on locking nut 5; Front end withstands in the blind hole on the set screw nut 3, and set screw nut 3 is 10mm with locking nut 5 spacings.
