Abstract
The utility model relates to a serpentine steel flex coupling, which comprises a cover shell, wherein the cover shell is annular; an assembly cavity is formed in the cover shell; two openings communicated with the assembly cavity are axially formed in the cover shell; a driving joint and a driven joint are arranged in the assembly cavity through the openings; sealing structural members are respectively arranged on parts, which are attached to the openings of the cover shell, of the driving joint and the driven joint; an edge is formed at one end of the driving joint and the driven joint which are positioned in the assembly cavity; gaps are distributed on the outer sides of the edges at equal intervals; and the gaps of the driving joint are linked and fixed with the gaps of the driven joint through a serpentine spring. The serpentine steel flex coupling is characterized in that each sealing structural member comprises a sealing positioning ring; the sealing positioning ring is an elastic structural member of which the cross section is L-shaped; the long end of the L-shaped elastic structural member is pressed between the cover shell and the serpentine spring to position the serpentine spring; and the short end of the L-shaped elastic structural member is compressed between the cover shell and the circumferential surface of the driving joint or the driven joint, so that an aim of sealing is fulfilled. By the technical scheme, the snake-shaped coupler is assembled stably and high in sealing property.
Description
Technical field
The utility model relates to a kind of coupling, is specifically related to a kind of Falk flexible coupling.
Background technique
Now, along with the application area of coupling is more and more wider, its usage requirement is also increasingly high.Existing Falk flexible coupling comprises case, serpentine spring, active joint and driven joint; Utilize serpentine spring along the limit moving the saving of principal and subordinate to be carried out UNICOM through initiatively joint and driven joint; Again case is coated on the connection position, initiatively joint is connected the purpose that reaches shaft coupling with driving shaft respectively again with driven joint with driven shaft, makes it to rotate jointly with transmitting torque; Traditional case only plays the effect of protection, and serpentine spring is easy to generate in working order and rocks.
Summary of the invention
To the deficiency that existing technology exists, the purpose of the utility model is to provide a kind of stable installation, the Falk flexible coupling of good airproof performance.
For realizing above-mentioned purpose; The utility model provides following technological scheme: comprise case, case is a ring-type, and the case set inside has installation cavity; Case axially is provided with two openings with installation cavity UNICOM; Initiatively joint and driven joint are arranged in the installation cavity through opening, and initiatively joint and driven joint and case opening joint place are respectively arranged with sealing component, and the end that active joint and driven joint are positioned at installation cavity is provided with along the limit; Along the breach that is equally spaced along the outside, limit; Through serpentine spring initiatively the breach of joint and driven joint link fixingly, it is characterized in that: said sealing component includes the sealing positioning ring, said sealing positioning ring is the L-shaped resilient member of cross section; Said L shaped long end is butted on the location of playing between case and the serpentine spring serpentine spring, and said L shaped short end is compressed in the effect of playing sealing between case and active joint or the driven joint side face.
Through adopting technique scheme, the setting of sealing positioning ring not only makes serpentine spring can accurately be fixed in case, and increases the sealing between case and active joint and the driven joint.
The utility model further is set to: be respectively arranged with auxiliary seal ring between the axial periphery face of said case and active joint and driven joint, said case is provided with the groove suitable with auxiliary seal ring.
Through adopting technique scheme, fitted seal positioning ring, auxiliary seal ring make the sealing effect in the case better.
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
