Abstract
The utility model discloses a double-diaphragm shaft coupling belonging to a shaft coupling of a mechanical driving device, and comprises a semi-coupling node 1.11, bolt groups 2,4,7,10, diaphragm groups 3,5,8,9 and a middle node 6. The double-diaphragm shaft coupling is characterized in that one group of diaphragms is increased on the basis of an original diaphragm shaft coupling, and the diaphragm groups are connected. The double-diaphragm shaft coupling can effectively complement bigger angular displacement, axial displacement and radial displacement, lowers stress forced by the diaphragms, and improves the service span of a shaft coupling.
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 a kind of novel elastic coupling flexible coupling, have and to transmit bigger torque, allow bigger Displacement error, allow high speed rotating, relax impact shock, generally need not lubricate, be convenient to advantages such as installation and maintenance, be widely used in industries such as military affairs, shipbuilding, aviation, petrochemical industry, machinery, can replace coupling arrangements such as gear coupling, rubbercushioned sleeve bearing coupling.Yet, because the structure of existing diaphragm coupling is very unreasonable, exist angle, axially, during radial displacement, the compensation ability deficiency of existing diaphragm coupling under the effect repeatedly of alternating stress, causes diaphragm to damage easily.The diaphragm damage can directly have influence on the safe in utilization and personal safety of coupled equipment, brings great loss for enterprise or individual.
Summary of the invention:
The technical problems to be solved in the utility model is, diaphragm group easy-rupturing phenomenon at existing diaphragm coupling existence, provide a kind of and can reduce axially, angle, radial displacement be to the influence of diaphragm usability, or improve angle, axial, radial displacement compensation rate, improve a kind of pair of diaphragm coupling in the working life of coupling.
The utility model provides a kind of a kind of pair of diaphragm coupling with following structure for solving above technical problem.It is by half-coupling 1,11, bolt group 2,4,7,10, and diaphragm group 3,5,8,9, middle segmentum intercalaris 6 is formed.Be characterized in, on the basis of original diaphragm coupling, increase by one group of diaphragm, with diaphragm group and diaphragm set associative, two diaphragm groups of composition link with half-coupling 1,11 and middle segmentum intercalaris 6 respectively again.
A kind of mode of execution preferably of present technique solution is, the connecting mode of this pair of diaphragm can have angle, axially, during radial displacement, reduce diaphragm effectively and bear extra bending load at coupling, improves the working life of coupling.
Present technique solution another kind is mode of execution preferably, it is characterized in that, the tinsel quantity of diaphragm group 3,5,8,9 is the 2-10 sheet.This structure and connecting mode can improve the reliability of connection.
The present technique solution the third preferably mode of execution be, bear extra bending load in order to reduce diaphragm, improve the working life of coupling, increased by one group of diaphragm.It is characterized in that, half-coupling, middle segmentum intercalaris respectively with the diaphragm set associative.
Because the utility model adopts the connecting mode of two diaphragm groups, make the more reasonable stress of coupling, reduced axially, the influence of displacement such as angle, thereby reduced the possibility that diaphragm is damaged, reach and improve the coupling purpose in working life.

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, found out by accompanying drawing, and a kind of pair of diaphragm coupling is by half-coupling 1,11, bolt group 2,4,7,10, and diaphragm group 3,5,8,9, middle segmentum intercalaris 6 is formed.
The diaphragm group is made up of 2-10 sheet foil 3c, and the centre is a circular port, and fastening ring group 3a, 3b are evenly distributed on circumference.
Working principle: moment of torsion is passed on the diaphragm group 3 through bolt group 2 by active half-coupling 1, segmentum intercalaris 6 during the bolt group 7 that links through bolt group 4, diaphragm group 5, with middle segmentum intercalaris 6 passes to again, pass to diaphragm group 8, bolt group 10 through bolt group 7 again, pass to driven half-coupling 11 through bolt group 2, finish the transmission of power and motion.
Embodiment 2, with reference to figure 3, found out by accompanying drawing, and a kind of pair of diaphragm coupling is by half-coupling 1,11, bolt group 2, diaphragm group 3,5, bolt group 4 compositions such as grade.
Working principle: moment of torsion is passed on the diaphragm group 3 through bolt group 2 by active half-coupling 1, passes to diaphragm group 5 through bolt group 4 again, through passing to driven half-coupling 11 with the driven half-coupling 11 bolt group 2 that links, finishes the transmission of power and motion again.
