Detailed description of the invention
It is described more fully with example embodiment referring now to accompanying drawing.But, example embodiment can be with multiple shape
Formula is implemented, and is not understood as limited to embodiment set forth herein；On the contrary, it is provided that these embodiments make the present invention incite somebody to action
Fully and completely, and by the design of example embodiment those skilled in the art is conveyed to all sidedly.Accompanying drawing identical in figure
Labelling represents same or similar structure, thus will omit their detailed description.
When the element of the present invention or the preferred embodiment of the present invention is described, word " ", " one ", " being somebody's turn to do " and " described " meaning
It is intended to refer to there is one or more element.Term " includes ", " comprising " and " having " etc. is intended to opening and refers to
Be in addition to listed element outside also can there is other element.
The uiform section design diaphragm coupling that prior art uses, when the outer load born is mainly displacement load and rotating speed load
During lotus, in the case of being unsatisfactory for intensity and Life Design, need to change the section thickness of diaphragm for convenience, but use and change
Prismatic diaphragm thickness is sometimes increased or decreased thickness all cannot make the stress of diaphragm coupling reduce.
Fig. 2 is a kind of diaphragm coupling stress envelope under spin load and drift angle load, as can be seen from Figure 2, film
Sheet shaft coupling the most not all sites stress is the highest, belongs to cycle of operation near the position of bolted connection 91
The middle region of high stress 93, the middle part then stress connecting sheet 92 is the most on the low side, for the mesolow power district 94 in cycle of operation, material
The utilization rate of material is the highest, and structure efficiency is relatively low, causes diaphragm coupling stress under many circumstances higher and weight lays particular stress on.
For above-mentioned stress distribution, as it is shown on figure 3, the present invention uses variable cross-section design to the diaphragm of diaphragm coupling, also
I.e. use variable cross-section diaphragm.The variable cross-section diaphragm of the embodiment of the present invention, can be used for but be not limited to for the embodiment of the present invention
Diaphragm coupling.The diaphragm coupling of the embodiment of the present invention, has the variable cross-section diaphragm of the embodiment of the present invention, can be used for electromotor
The use occasion such as accessory drive.The variable cross-section diaphragm of the embodiment of the present invention, it is also possible to the field needing to use diaphragm for other
Close.
As it is shown on figure 3, the variable cross-section diaphragm of the embodiment of the present invention, including multiple bolted connection 1 and connection sheet 2, multiple
Bolted connection 1 is positioned on same circumference, and as shown in Figure 4, it is the center of circle that these multiple bolted connection 1 are positioned at same center of circle O
On the circumference of reference circle；In the present embodiment, the number of bolted connection 1 is 6, and 6 bolted connection 1 and 6 connection sheets 2 can
With one-body molded, but the present invention is not limited thereto, and the number of bolted connection 1 can be 4,8 etc., and bolted connection 1
Number with connect sheet 2 number identical.
Bolted connection 1 includes cylindrical portion 11 and bolt hole 10, and bolt hole 10 is opened in the shaft core position of cylindrical portion 11 also
There is female thread.Connect sheet 2 to be then connected between adjacent two bolted connection 1, be particularly connected to adjacent two spiral shell
Between the cylindrical portion 11 of bolt connecting portion 1, connect sheet 2 and have at thickness minimum, to the company between bolted connection 1 at thickness minimum
The thickness of contact pin 2 is gradually increased and smoothly transits.
Here thickness, refers to that the upper surface connecting sheet 2, to the distance of lower surface, is also to extend by being perpendicular to connection sheet 2
The plane in direction goes to cut the height in the cross section connecting sheet 2 gained, the change of thickness namely the change of depth of section.And connect sheet 2
E.g. straight-line extension between two bolted connection 1, then to connect the cross section of each position on sheet 2 the most parallel, connect
The gradual change of sheet 2 thickness namely the gradual change of above-mentioned depth of section.And the variable cross-section diaphragm of the embodiment of the present invention, its described variable cross-section
Mainly connecting the variable cross-section in the above-mentioned cross section of sheet 2, it is less and close that the thickness of connection sheet 2 is designed as connecting sheet 2 interior thickness
Connection sheet 2 thickness at bolted connection 1 is relatively big, and connects the thickness of sheet 2 relative to using symmetric design at thickness minimum.
And at for thickness minimum, can have two embodiments, one is that thickness minimum is at geometry intermediate cross-section 20, should
The distance of the bolted connection 1 of its both sides of cross-sectional distance is identical, and connects on sheet 2 with geometry intermediate cross-section 20 apart from phase etc.
The thickness connecting sheet 2 is the most identical, namely relative to geometric center cross section 20 symmetric design.The two ends connecting sheet 2 are respectively connection
End 21,22, connects the bolted connection 1 of both sides respectively.Connect sheet 2 and connect the maximum of the thickness at end 21,22, close to cylinder
The height in portion 11.
Meanwhile, in the present embodiment, the thickness connecting the minimum thick bottom of sheet 2 is designed to about connect the company at sheet 2 two ends
Connect 1/2nd of end 21,22 thickness, and the thickness of whole connection sheet 2 smoothly transits along the length connecting sheet 2.But this
Bright be not limited thereto, connect the thickness at the minimum thickness of sheet 2 can be connect end 21, the 22 thickness end 1 to four/3rds/
Any value between three, for example, 3/4ths, 5/8ths, three/first-class.
Described above is all the thickness connecting sheet 2, as it is shown on figure 3, the width connecting each position of sheet 2 can be homogeneous
With.It addition, the variable cross-section diaphragm of the embodiment of the present invention can have axial centre plane, and the variable cross-section diaphragm of the embodiment of the present invention
Symmetrical above and below relative to described axial centre plane.Meanwhile, the material of the variable cross-section diaphragm of the embodiment of the present invention can be rustless steel,
High-strength spring steel or titanium alloy etc..
The diaphragm coupling of the embodiment of the present invention is carried out simulation calculation, by the diaphragm coupling of present invention design, weight
Amount alleviates about 8%, and stress reduces about 10%, and resultant effect is the most obvious.
Should be understood that multiple example described above can along multiple directions (as tilted, reverse, level, vertical, etc.) and
It is utilized with multiple structures, without departing from the principle of the present invention.Embodiment shown in accompanying drawing is only used as the principle of the present invention
