Description
Technical field
The present invention relates to frame for movement technical field, specially a kind of convoluted diaphragm structure, suitable for shaft coupling field.
Background technique
In shaft coupling field, metallic membrane is widely used, significant effect as a kind of variable bit transfer medium, uses
Service life.In long-term use, the radial rigidity of diaphragm is big many relative to axial direction, angular stiffness, and radial rigidity will have one
A reasonable value, too big that a big radial force can be then generated to machine tool and working machine, too small there will be the possibility for generating resonance.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of convoluted diaphragm structure, this convoluted diaphragm structure can be greatly
Radial force is reduced, the bearing of host and working machine, the service life of sealing ring are greatly improved, can greatly reduce installation length
Degree.
In order to solve the above technical problems, convoluted diaphragm structure of the invention, including it is provided with the diaphragm structure middle position
Through slot, part between the diaphragm structure outer edge and through slot forms S-shaped rugosity ripple struction, the diaphragm structure outer edge
Equipped with multiple lugs, the through-hole for connecting external devices is offered on the lug.
As a currently preferred technical solution, the through slot is round through slot.
As a currently preferred technical solution, S-shaped rugosity ripple struction is surrounded on the diameter of round through slot circumference
To.
As a currently preferred technical solution, the diaphragm structure with a thickness of 1~3mm.
As a currently preferred technical solution, the lug and the diaphragm structure are integrally formed.
As a currently preferred technical solution, shape connection of girdling the waist between multiple lugs.
As a currently preferred technical solution, the adjacent protrusion in S-shaped rugosity ripple struction two sides is relative to convex
Ear height is consistent, is 2~6mm.
The beneficial effects of the present invention are:
1. radial force can be reduced greatly, the bearing of host and working machine, the service life of sealing ring are greatly improved.
2. installation length can be reduced greatly, in order to compensate for radial missing displacement, the method used now is using two-wheel
Diaphragm adds intermediate shaft structure, and a wheel convoluted diaphragm now can be used, do not have to jackshaft, so that it may achieve the effect that compensation.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
As shown, this convoluted diaphragm structure includes the through slot 3 for being provided with the diaphragm structure middle position, the diaphragm knot
Part between structure outer edge and through slot 3 forms S-shaped rugosity ripple struction 1, which is equipped with multiple lugs
2, the through-hole 4 for connecting external devices is offered on the lug 2；For example, above-mentioned through slot is for working machine or master
The axis body of machine passes through, and external devices are shaft coupling, which is connected thereto installation by through-hole 4, it should be noted that at one
In embodiment, this convoluted diaphragm structure uses metal material.
In one embodiment of the invention, the through slot 3 is round through slot.
As in currently preferred one embodiment, S-shaped rugosity ripple struction 1 is surrounded on the diameter of round through slot circumference
To.
In one embodiment of the invention, the diaphragm structure with a thickness of 2mm.
In currently preferred one embodiment, the lug 2 is integrally formed with the diaphragm structure.
Shape of girdling the waist in currently preferred one embodiment, between multiple lugs 2 connects.
In currently preferred one embodiment, the adjacent protrusion in S-shaped rugosity ripple struction two sides is relative to lug 2
Height is consistent, is 5mm.
In order to better understand the present invention, by taking shaft coupling as an example, the metallic membrane in shaft coupling will have power transmission, correction two
A function, wherein wherein correction should be X Y Z displacement variation, variable quantity=△ KXL, L is elastic element stressed length, one
Then radial rigidity is with regard to small greatly for the radial-deformation of diaphragm under the action of fixed radial force, and as shown in Figure 2, Figure 4 shows, existing diaphragm is only
There is increased radius value to can be only achieved the purpose for increasing radial-deformation, and convoluted diaphragm structure proposed by the present invention, same
Under radius, so that it may it is easily reached the target for increasing radial-deformation, under conditions of same deflection, the radial direction of convoluted diaphragm generation
Power wants much less, because the mechanism that they are generated is entirely different, existing diaphragm will generate radial elastic stretching, the tension with diaphragm
Intensity δ b is related, and convoluted diaphragm structure of the invention generates radial elastic and stretches in a certain range the only shearing with diaphragm
Intensity τ is related, and τ is 0.2-0.5 times of δ b, for example, the δ of τ=0.4 b.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
