Abstract
The invention discloses a rotation-stopping adjusting thread structure. At least one rotation-stopping male tooth is arranged on a matched tooth surface of an external thread of a screw rod, and a plurality of rotation-stopping female teeth divided by angles are arranged on a matched tooth surface of an internal thread of a nut. By arranging the rotation-stopping teeth on the matched tooth surfaces of the internal thread and the external thread, a male thread and a female thread do no relatively slide due to the meshing of the rotation-stopping teeth, so that the self-locking capacity of the threads is guaranteed.
Description
Technical field
The present invention relates to a kind of screw-thread fit mechanism, refer to that a kind of spline regulates worm structure especially.
Background technique
Screw thread general at present, particularly triangle fine thread, itself also possesses self-lock ability, but this self-lock ability reliability is not high, particularly having the environment of vibrations, not adding in other spline structure situations, is also be easier to get loose, and universal threaded by screw thread accurately location fit position itself, cannot need other structure auxiliary positioning when applying to regulation structure.
Summary of the invention
The object of this invention is to provide one makes male and female screw thread can not relative sliding and ensure that the reliable spline of screw thread self-locking ability regulates worm structure.
For achieving the above object, solution of the present invention is:
A kind of spline regulates worm structure, wherein: on the cooperation flank of tooth of external thread of screw, be provided with the public tooth of at least one spline, and on the screw-internal thread fit flank of tooth of nut, arranges the female tooth of spline of several angularly deciles.
The cooperation flank of tooth of described external thread of screw is provided with the public tooth of several splines of angularly decile, and the decile angle of the male tooth of externally threaded spline is the multiple proportion of point angles such as the female tooth of internal thread spline.
The non-fitting surface of described external thread of screw and nut inner thread leaves the gap that is highly greater than the public tooth height of spline.
Spring is equipped with between described nut and screw rod.
A kind of spline regulates worm structure, wherein: the female tooth of spline arranging several angularly deciles on the cooperation flank of tooth of external thread of screw, and on the screw-internal thread fit flank of tooth of nut, is provided with the public tooth of at least one spline.
The screw-internal thread fit flank of tooth of described nut is provided with the public tooth of several splines of angularly decile, and the decile angle of the male tooth of spline of internal thread is the multiple proportion of point angles such as the female tooth of outside thread spline.
The non-fitting surface of described external thread of screw and nut inner thread leaves the gap that is highly greater than the public tooth height of spline.
Spring is equipped with between described nut and screw rod.
After adopting such scheme, by the engagement of baffle teeth, the present invention, by being provided with some baffle teeths on the cooperation flank of tooth of internal and external screw thread, ensures that male and female screw thread can not relative sliding.This thread mechanism mainly applies to the pressure or the position fine adjustment structure that need reliable spline.This structure can the engaging position of fine adjustment screw thread, thus screw rod or nut is accurately positioned in desired location, or converts accurate force value to by exact position.
Accompanying drawing explanation
Fig. 1 is the structural representation of external thread of screw of the present invention;
Fig. 2 is the structural representation of nut inner thread of the present invention;
Fig. 3 be screw rod of the present invention with nut coordinate schematic diagram;
Fig. 4 is the partial enlarged drawing of Fig. 3.
Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As shown in Figures 1 to 4, present invention is disclosed a kind of spline and regulate worm structure, outside thread on screw rod 1 coordinates the public tooth 1a of several splines flank of tooth 1b arranging or angularly decile; And the cooperation flank of tooth 2b of internal thread on nut 2 is provided with the female tooth 2a of spline of several angularly deciles, the decile angle θ 1 of the male tooth 1a of externally threaded spline is the multiple proportion of the decile angle θ 2 of the female tooth of internal thread spline, to ensure the reliable fit of baffle teeth.
If the female tooth n of spline is arranged at internal thread top, so
,
n be more than or equal to 1 integer.
If nut 2 rotates relative to screw rod 1 during operation
individual tooth, so nut 2 angle of rotating relative to screw rod 1
.If the pitch of screw thread is P, now nut 2 in the axial direction relatively screw rod 1 to have moved distance
.If be assembled with spring n1 that elasticity coefficient is K between nut 2 and screw rod 1, so this controlling mechanism just can increase or reduce pressure
Screw rod 1 and nut 2 after installing as shown in Figure 3, need during whole institution staff to apply the power as Fig. 3 filled arrows direction at nut 2, ensure that the fitting surface 2b of nut 2 is close on the fitting surface 1b of screw rod 1, in the female tooth 2a of spline on spline male tooth 1a insert nut 2 now on screw rod 1, prevent whole mechanism group from relatively rotating when long-term vibration.
When impaction state, the non-fitting surface of the outside thread of screw rod 1 and the internal thread of nut 2 will leave a gap S, and gap S needs the height being greater than the public tooth 1a of spline.Like this when needing the relative position adjusting screw rod 1 and nut 2, as Fig. 3 hollow arrow is put to screw box, the position turning to needs decontrols nut 2 again, get back on working position under the effect of such nut 2 just filled arrows power in the drawings, the male tooth 1a of spline and the female tooth 2a engagement of spline, prevent screw rod 1 and nut 2 from relatively rotating.
Certainly, the public tooth of described spline can be arranged on the cooperation flank of tooth of the internal thread of nut, then the female tooth of spline is just arranged on the cooperation flank of tooth of external thread of screw, can realize above-mentioned functions equally.
In sum, the present invention mainly applies to the pressure or the position fine adjustment structure that need reliable spline.This structure can the engaging position of fine adjustment screw thread, thus screw rod 1 or nut 2 is accurately positioned in desired location, or converts accurate force value to by exact position.
The above is only preferred embodiment of the present invention, not imposes any restrictions technical scope of the present invention, therefore the change in every case done according to claim of the present invention and specification or modification, all should belong within scope that patent of the present invention contains.
