Abstract
The utility model discloses an arched diaphragm coupling, which belongs to a coupling of a mechanical drive. The diaphragm coupling comprises shafts (1, 1'), keys (2, 2'), half couplings (3, 3'), bolt assemblies (4, 4'), a diaphragm assembly (5) and the like. The diaphragm coupling is characterized in that on the basis of the prior diaphragm coupling, the structure and shape of the diaphragm assembly are changed, and the diaphragm assembly is of a strip-shaped arched structure. The technical problem which the utility model needs to solve is to provide the arched diaphragm coupling which can compensate certain radial, angular and axial displacement, reduce the stress on the diaphragm, decrease the affection of the error of the space between bolt holes, improve the operating conditions and prolong the service life.
Description
Technical field:
The utility model relates to a kind of coupling of mechanical transmission, is the motion between prime mover (as motor, internal-combustion engine etc.) and the working machine (as pump, speed reducer etc.), the coupling arrangement of transmission of power.
Background technique:
Diaphragm coupling is widely used in industries such as military affairs, shipbuilding, aviation, petrochemical industry, machinery.Because its have certain compensation radially, angle, axial displacement and do not need to lubricate, can replace coupling arrangements such as gear coupling, rubbercushioned sleeve bearing coupling.Diaphragm in the diaphragm coupling is an easily damaged parts, needs timely maintenance, replacing after work a period of time.Because the alignment error that error that produces in the diaphragm manufacturing process and diaphragm coupling installation process produce, make that coupling is easy to generate radially, angle, axial displacement, or cause the diaphragm applied force inequality, cause diaphragm to bear additional stress thus.Additional stress makes the diaphragm coupling operating conditions worsen, and diaphragm damages easily.In addition, local additional stress can have influence on the applying working condition of whole diaphragm in the diaphragm that manufacturing or alignment error cause, and falls short of problems such as the easy fracture of diaphragm so traditional diaphragm coupling exists working life.The coupling damage can cause associate device to shut down, and increases the device maintenance time, improves cost of production, even security incident may occur.
Summary of the invention:
The technical problems to be solved in the utility model is, provides a kind of and can simplify diaphragm structure, reduces the suffered stress of diaphragm, improves working conditions, and improves the arc diaphragm coupling of diaphragm coupling usability.
The utility model provides a kind of arc diaphragm coupling with following structure for solving above technical problem.It is by axle (1,1 '), key (2,2 '), half-coupling (3,3 '), bolt group (4,4 '), diaphragm group compositions such as (5).Be characterized in that on the basis of original diaphragm coupling, change diaphragm group structure and shape, diaphragm is the strip bow-shaped structural.
A kind of mode of execution preferably of present technique solution is, the profile of this arc diaphragm and and the mode that is fixedly connected of half-coupling, both can have axial when waiting displacement, reduce diaphragm effectively and bear extra bending load, can also solve the influence of the additional stress that produces because of bolt hole interval error in the manufacture process effectively, the working life of improving coupling to whole diaphragm group.
Present technique solution another kind is mode of execution preferably, it is characterized in that, the tinsel quantity of diaphragm group (5) determines that according to the coupling size its monolithic quantity is the 2-10 sheet.
Because the utility model adopts arc diaphragm, make the more reasonable stress of diaphragm group, the influence that reduced radially, angle, displacement such as axial and bolt hole interval error produces, thereby reduced the possibility that diaphragm is damaged, reached the purpose that improves coupling working life, improves the reliability that connects.

Fig. 3---arc diaphragm group structural representation
Embodiment:
Provide embodiment of the present utility model below in conjunction with accompanying drawing, be used for further specifying technical solution.
Embodiment 1, with reference to figure 1, Fig. 2.Find out that by accompanying drawing arc diaphragm coupling is by axle (1,1 '), key (2,2 '), half-coupling (3,3 '), bolt group (4,4 '), diaphragm group compositions such as (5).Be characterized in that on the basis of original diaphragm coupling, change diaphragm group structure and shape, the diaphragm group is the strip bow-shaped structural.
With reference to figure 3, diaphragm group (5) is made the arc foil of strip (6) by the 2-10 sheet and is formed, and the centre is a circular port, links together by compressing clasp group (7).
Working principle: moment of torsion is passed on the half-coupling (3) through key (2) by axle (1).Because half-coupling (3) and diaphragm group (5) adopt the articulation hole Bolt Connection, be that bolt group (4) and half-coupling (3) and diaphragm group (5) adopt cooperation to connect, so moment of torsion passes on the bolt group (4) from half-coupling (3), by bolt group (4) moment of torsion is passed on the diaphragm group (5).And diaphragm group (5) passes to the bolt group (4 ') of opposite side with moment of torsion, and the half-coupling (3 ') of this bolt group and opposite side links, so moment of torsion is passed to key (2 '), axle (1 ') is finished the transmission of power and motion.
In like manner, the technical solution according to the utility model provides can also provide other embodiment.
As comparing with above embodiment 1, the structure of other parts is constant, and only changes the embodiment of tinsel quantity on the transition diaphragm.
Claims (2)
1. arc diaphragm coupling, it is by axle (1,1 '), key (2,2 '), half-coupling (3,3 '), bolt group (4,4 '), diaphragm group compositions such as (5) is characterized in that diaphragm group (5) is the strip bow-shaped structural.
2. according to claim 1, the tinsel quantity of diaphragm group (5) determines that according to the coupling size quantity is the 2-10 sheet.
