Abstract
The utility model discloses a kind of dextrorotation round nut, comprise a main structure body, this main structure body is an annulus, arranges organize screw thread more in described annulus inner ring, and described annulus comprises the round cap and pillar that are connected, and described screw thread is the right-handed thread of inverted trapezoidal.By inner ring trapezoidal groove composition screw thread, just can realize tightening fixing without the need to appended claims, structure is simple, be convenient to large-scale promotion and use, and cost is low, effectively economizes on resources, and meets effective use of different field and special screne.
Description
Technical field
The utility model relates to a kind of joint, is specifically related to a kind of dextrorotation round nut.
Background technique
Round nut is normal with round nut lock washer adapted, inserted in the groove on axle by tongue in packing ring, and by the groove of the outer tongue embedding round nut of packing ring, namely nut is locked during assembling.The axial restraint of Chang Zuowei rolling bearing.Conventional rounding nut is because of screw thread and precision problem thereof, and often needing extra anti-take-up to assist use to realize, it is firm.
At present, when the end of major diameter axostylus axostyle needs nut to tighten, because axostylus axostyle is major diameter, so nut is not easy to tighten, and machinery vibrations operationally also can cause nut generation to loosen, and can cause degradation during mechanical movement, even can lead to a disaster.For preventing the generation of nut loosening phenomenon, have special locking nut, but this locking nut should punch on axostylus axostyle, nut simultaneously, twines after mounting again and ties up iron wire, and can not reuse; Also there is a kind of locking nut encapsulating to realize, can not reuse equally; Also have and use anti-loosening left-right rotary screw thread combination bolt and nut, this assembling bolt nut is by reciprocity law power when left-right rotary screw bolt, nut screw connection, reaches anti-loosening effect.But two nuts come anti-loosening by frictional force, and due to the effect of frictional force, can make set screw nut Hui Song, locking effect is not very good yet; And constantly reciprocity law power can make frictional force constantly change, such pretightening force is just not easily predicted; When needing locking to major diameter axle head, be also not easy to tighten.
In a word, traditional round spin nut will realize tightening fixing, all needs extra annex to realize.
Model utility content
The purpose of this utility model is to provide a kind of dextrorotation round nut.
A kind of dextrorotation round nut, comprise a main structure body, this main structure body is an annulus, arranges organize screw thread more in described annulus inner ring, and described annulus comprises the round cap and pillar that are connected, and described screw thread is the right-handed thread of inverted trapezoidal.
Especially, described round cap cross-section area is greater than described pillar cross-section area.
Especially, described pillar is cylindrical body or regular polygon structure.
Especially, described screw thread is made up of the trapezoidal groove regular array that many groups cave inward.
Especially, the interior chamfering of described screw thread is less than 90 degree, and interior chamfering top is not higher than described circle ring inner surface height.
The beneficial effects of the utility model are: the dextrorotation round nut that the utility model provides, by inner ring trapezoidal groove composition screw thread, just can realize tightening fixing without the need to appended claims, structure is simple, be convenient to large-scale promotion use, and cost is low, effectively economize on resources, meet effective use of different field and special screne.
Accompanying drawing explanation
Fig. 1 is the structural representation of dextrorotation round nut;
Fig. 2 is the worm structure schematic diagram of dextrorotation round nut
001 annulus, 002 screw thread, 003 circle cap, 004 pillar.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1-2 show schematically show according to a kind of dextrorotation round nut of the present utility model.
A kind of dextrorotation round nut that the present embodiment provides, as shown in Figures 1 and 2, comprise a main structure body, this main structure body is an annulus 001, in described annulus inner ring, many group screw threads 002 are set, described annulus 001 comprises the round cap 003 and pillar 004 that are connected, and described screw thread 002 is the right-handed thread of inverted trapezoidal.
Especially, described round cap 003 cross-section area is greater than described pillar 004 cross-section area.
Especially, described pillar 004 is cylindrical body or regular polygon structure.
Especially, described screw thread 002 is made up of the trapezoidal groove regular array that many groups cave inward.
Especially, the interior chamfering of described screw thread 002 is less than 90 degree, and interior chamfering top is not higher than described circle ring inner surface height.
A kind of dextrorotation round nut of the dextrorotation round nut that the utility model provides, by inner ring trapezoidal groove composition screw thread, just can realize tightening fixing without the need to appended claims, structure is simple, be convenient to large-scale promotion use, and cost is low, effectively economize on resources, meet effective use of different field and special screne; The utility model illustrates implementation method of the present utility model and apparatus structure by above-described embodiment; but the utility model is not limited to above-mentioned mode of execution; namely do not mean that the utility model must rely on said method and structure could be implemented; person of ordinary skill in the field should understand; to any improvement of the present utility model; implementation method equivalence selected by the utility model is replaced and and the interpolation of step, concrete way choice etc., all drop within protection domain of the present utility model and open scope.
Finally should be noted that; above embodiment is only in order to illustrate the technical solution of the utility model; but not the restriction to the utility model protection domain; although done to explain to the utility model with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify to the technical solution of the utility model or equivalent replacement, and not depart from essence and the scope of technical solutions of the utility model.
