Abstract
The invention discloses an elastic connecting piece on a coupler for prolonging the service life; the elastic connecting piece is formed by punching, and comprises a circular steel piece; the center of the circular steel piece is provided with a central circular hole; a plurality of connecting holes are uniformly distributed around the circumferential direction of the circular steel piece; and sharp bulges for making sure that the connecting holes are arranged at the same circumferential positions when being installed and formed are arranged on the side surface of the outer circumference of the circular steel piece. When the elastic connecting piece is used, the stress on all steel pieces is uniform, so that the steel pieces are effectively prevented from being broken, and the service life of the elastic connecting piece is prolonged.
Description
Technical field
The present invention relates to a kind of flexible connection piece for improving the life-span on the coupling, be specifically related to a kind of can effectively overcome since positioning tolerance cause one group connect can not producing balanced forces a kind of for the flexible connection piece on the coupling.
Background technique
The two ends of coupling connect respectively driving shaft and driven shaft, make it jointly to rotate with transmitting torque.When the load of driven shaft was larger, the moment of torsion that coupling will carry was larger, has preferably anti-twisting property in order to make coupling, usually at coupling flexible connection piece is set, with the suffered torsion of main carrying coupling.
Flexible connection piece adopts the steel sheet material and by impact briquetting, in order to reach certain anti-twisting property, connecting sheet is to use in groups, and several pieces connecting sheets superpose vertically and are connected on the coupling by circumferential several uniform attachment holes.
The coupling that is provided with at present flexible connection piece such situation can occur in use, often slight crack occurs on one, two flexible connection piece therein, and slight crack generally comes from the connection hole.By analysis, reason be stamping forming flexible connection piece on it circumferential position of attachment hole have certain positioning tolerance, the multi-disc flexible connection piece when mounted, because the circumferential position tolerance of attachment hole, so that the concentricity of each the group attachment hole on one group of connecting sheet is relatively poor, like this connecting sheet when carrying torsion, can not the while balancedly stressed, and wherein one, two connecting sheet acts on connecting bolt and carries torsion often, and this phenomenon fails to be well solved always.
Summary of the invention
The objective of the invention is the defective that exists in the above-mentioned prior art in order to solve, a kind of flexible connection piece for improving the life-span on the coupling is provided, and the position of the position of this connecting sheet when installing during with impact briquetting is consistent effectively to eliminate and processes and the positioning tolerance of formation during installation.
In order to achieve the above object, the invention provides a kind of flexible connection piece for improving the life-span on the coupling, this flexible connection piece is formed by steel plate punched, comprises a circular steel disc; This circle steel disc center is provided with center hole, and along circumferential several the uniform attachment holes of described steel disc, circular steel disc outer circumferential sides face is provided with for guaranteeing that attachment hole is in the sharp protruding of same circumferential position when installing with moulding.
Sharp protruding circular-arc projection for being smoothly connected with described flexible connection piece excircle wherein.
Each steel disc adopts 50CrV, and thickness is 0.5mm.
When flexible connection piece of the present invention is applied on the coupling, be respectively equipped with above-mentioned flexible connection piece between the driven transmission body outer end of coupling, active transmission body and the driven transmission body.Initiatively the corresponding position of the attachment hole of transmission body and driven transmission body and flexible connection piece is respectively equipped with bolt connecting hole; Flexible connection piece passes attachment hole by bolt respectively and links to each other with driven transmission body with the active transmission body with bolt connecting hole; Bolt is provided with sleeve outward.
The present invention has the following advantages compared to existing technology:
1, by the sharp protruding attachment hole location of carrying out on the flexible connection piece, guarantee that attachment hole is in same circumferential position when installing with moulding, thereby the tolerance that exists between the attachment hole when eliminating owing to steel disc production, so that the multi-disc flexible connection piece in use, stressed even, effectively prevent the flexible connection piece fracture, increased the working life of connecting sheet.
2, when utilizing bolt to be assembled to this flexible connection piece on the coupling, effectively increase assembly precision by the overcoat cylinder.
Description of drawings
Fig. 1 is for forming the structural representation of flexible connection piece of the present invention;
Fig. 2 is the structural representation of the coupling of employing flexible connection piece of the present invention.
Among the figure, the 1-flexible connection piece, the 2-attachment hole, the 3-point is protruding, the driven transmission body of 4-, 5-is transmission body initiatively, 6-sleeve, 7-bolt.
Embodiment
Below in conjunction with accompanying drawing the flexible connection piece that the present invention is used on the coupling is elaborated.
The flexible connection piece 1 of present embodiment is the circular steel disc that the 50CrV steel plate punched of 0.5mm forms by thickness, its structure as shown in Figure 1, stamping forming flexible connection piece 1 thickness is 0.5mm, outside diameter is 130mm, the centre is provided with the center hole that diameter is 52mm, along the attachment hole 2 that circumferential uniform 4 diameters are 15mm, flexible connection piece 1 excircle side is provided with point protruding 3, sharp protruding 3 and flexible connection piece 1 excircle is smoothly connected.Point protruding 3 is circular-arc, and radius is 1.5mm, and the center of circle is on the excircle of flexible connection piece 1.
Above-mentioned flexible connection piece 1, be used for being installed on the coupling, it is 6 such as one group of connecting sheet, during installation, sharp protruding 3 alignment with 6 flexible connection pieces 1, the circumferential position of circumferential position when the upper attachment hole 2 that has guaranteed like this each flexible connection piece 1 is installed during with impact briquetting is consistent, thereby eliminates owing to install and the accumulation of the inconsistent positioning tolerance that causes of moulding two positions.
The specific embodiment that flexible connection piece shown in Figure 1 is used for a coupling such as Fig. 2.This coupling comprises driven transmission body 4 and the active transmission body 5 that is attached thereto.Coupling links to each other with driving shaft with the driven shaft of different institutions with active transmission body 5 by driven transmission body 4 respectively.Above-mentioned flexible connection piece 1 is provided with two groups, every group 6, one is mounted on the outer end of driven transmission body 4, passes the bolt connecting hole (not shown) that two attachment holes on flexible connection piece 1 Vertical direction and driven transmission body 4 corresponding positions are provided with by bolt 7, is fixedly linked with driven transmission body 4; Another is mounted on driven transmission body 4 and initiatively between the transmission body 5, passes successively two attachment holes and transmission body 5 initiatively on driven transmission body 4, flexible connection piece 1 substantially horizontal by bolt 7, is fixed on driven transmission body 4 and initiatively between the transmission body 5.Attachment hole upper sleeve through sleeve 6, bolt 7 are set in the sleeve 6, and the smooth surface by sleeve 6 makes each connecting sheet can uniform stressed.
