Abstract
The utility model discloses a regulation helicitic texture splines wherein is equipped with at least one public tooth that splines, and sets up a plurality of according to the female tooth of splining of angle partition on the internal thread engaging teeth of nut face on the engaging teeth of screw rod external screw thread face. The utility model discloses an including, be provided with a plurality of teeth that splines on the engaging teeth face of external screw thread, guarantee through the meshing of the tooth that splines that public box thread can not the relative slip, guarantee the auto -lock ability of screw thread.
Description
Technical field
This utility model relates to a kind of threaded engagement mechanism, particularly relates to a kind of spline regulation helicitic texture.
Background technology
The most general screw thread, particularly triangle fine thread, itself also possess self-lock ability, but this self-lock ability can
The highest by property, particularly there iing the environment of vibrations, in the case of being not added with other spline structures, be also to be easier to get loose, and lead to
Cooperation position cannot be accurately positioned by screw thread itself with screw thread, apply to during adjustment structure, need other structure auxiliary positioning.
Utility model content
The purpose of this utility model is to provide one makes male and female screw thread will not relatively slide and ensure that screw thread self-locking ability can
The spline regulation helicitic texture leaned on.
For achieving the above object, solution of the present utility model is:
A kind of spline regulation helicitic texture, wherein: on the cooperation flank of tooth of external thread of screw, be provided with at least one spline public
Tooth, and spline mother's tooth of several angularly deciles is set on the screw-internal thread fit flank of tooth of nut.
The flank of tooth that coordinates of described external thread of screw is provided with several spline public affairs teeth of angularly decile, externally threaded spline
The decile angle of male tooth is the multiple proportion of point angles such as female thread spline mother's tooth.
The height gap more than spline public affairs tooth height is left in the non-cooperation face of described external thread of screw and nut inner thread.
It is equipped with spring between described nut and screw rod.
A kind of spline regulation helicitic texture, wherein: several are set on the cooperation flank of tooth of external thread of screw angularly etc.
The spline mother's tooth divided, and on the screw-internal thread fit flank of tooth of nut, it is provided with at least one spline public affairs tooth.
The screw-internal thread fit flank of tooth of described nut is provided with several spline public affairs teeth of angularly decile, the spline of female thread
The decile angle of male tooth is the multiple proportion of point angles such as external screw thread spline mother's tooth.
The height gap more than spline public affairs tooth height is left in the non-cooperation face of described external thread of screw and nut inner thread.
It is equipped with spring between described nut and screw rod.
After using such scheme, this utility model is by being provided with some splines in coordinating of internal and external screw thread on the flank of tooth
By the engagement of baffle teeth, tooth, ensures that male and female screw thread will not slide relatively.This thread mechanism mainly applies to need reliable spline
The accurate adjustment structure of pressure or position.This structure can accurately regulate the position of engagement of screw thread, thus by accurate to screw rod or nut
It is positioned in desired location, or is converted into accurate force value by exact position.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model external thread of screw；
Fig. 2 is the structural representation of this utility model nut inner thread；
Fig. 3 be this utility model screw rod with nut coordinate schematic diagram；
Fig. 4 is the partial enlarged drawing of Fig. 3.
Detailed description of the invention
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figures 1 to 4, this utility model discloses a kind of spline regulation helicitic texture, the external screw thread on screw rod 1
Coordinate several splines public affairs tooth 1a that or angularly decile are set on flank of tooth 1b；And the cooperation of the female thread on nut 2
Being provided with the spline mother tooth 2a of several angularly deciles on flank of tooth 2b, the decile angle, θ 1 of externally threaded spline public affairs tooth 1a is interior
The multiple proportion of the decile angle, θ 2 of thread rotation stopping mother's tooth, to ensure the reliable fit of baffle teeth.
If female thread top has spline mother tooth n, then,N is the integer more than or equal to 1.
If nut 2 rotates relative to screw rod 1 during operationIndividual tooth, then the angle that nut 2 rotates relative to screw rod 1.If the pitch of screw thread is P, now nut 2 has moved distance relative to screw rod 1 in the axial direction。
If being assembled with spring n1 that coefficient of elasticity is K between nut 2 and screw rod 1, then this governor motion just can be increased or decreased
Pressure
As it is shown on figure 3, need when whole mechanism works to apply one such as Fig. 3 in fact at nut 2 after screw rod 1 and nut 2 are installed
The power of the heart direction of arrow, it is ensured that the cooperation face 2b of nut 2 is close on the cooperation face 1b of screw rod 1, the now spline public affairs tooth on screw rod 1
In spline mother tooth 2a on 1a inserted num 2, prevent whole mechanism group from relatively rotating when long-term vibration.
When impaction state, a gap S is left in the non-cooperation face of the external screw thread of screw rod 1 and the female thread of nut 2,
Gap S needs the height more than spline public affairs tooth 1a.So when needing the relative position adjusting screw rod 1 and nut 2, as Fig. 3 is hollow
Arrow is put to screw box, and the position turning to need decontrols nut 2, the work of such nut 2 filled arrows power the most in the drawings again
Return under with on operating position, spline male tooth 1a and the engagement of spline mother's tooth 2, prevent screw rod 1 and nut 2 from relatively rotating.
Certainly, on the cooperation flank of tooth of the female thread that described spline public affairs tooth may be provided at nut, then spline mother tooth is just arranged
On the cooperation flank of tooth of external thread of screw, equally realize above-mentioned functions.
In sum, this utility model mainly applies to need the accurate adjustment structure of the pressure of reliable spline or position.Should
Structure can accurately regulate the position of engagement of screw thread, thus screw rod 1 or nut 2 is accurately located in desired location, or by essence
Really position is converted into accurate force value.
The above, be only preferred embodiment of the present utility model, not make technical scope of the present utility model
Any restriction, therefore the change in every case done according to claim of the present utility model and description or modification, all should belong to this practicality
Within the scope of new patent is contained.
