The utility model discloses a roller-diaphragm combined coupling, belonging to a coupling of mechanical transmission devices. The coupling consists of an external gear ring 1, a drum-shaped roller 2, an internal gear ring 17, a diaphragm group 11, a half coupling 16, and the like. The roller-diaphragm combined coupling is characterized in that the drum-shaped roller 2 is arranged inside a dentiform trough that is arranged between the external gear ring 1 and the internal tooth gear 17; the external gear ring 1, a screw 5 and a pressing plate can restrict the drum-shaped roller 2 from moving in an axial direction; an end cover 4 is fixed on the internal gear ring 17 by a screw 18, thus tightly pressing a sealing ring 3; the end cover 15 is fixed on the internal gear ring 17 by a screw 13, thus tightly pressing the sealing ring 14; the diaphragm group 11 is assembled together by a fixed pin 10 and a fixed sleeve 12; and spring washers 9 are fixed on the internal gear ring 17 and the half coupling 16 respectively by a bolt 7 and a nut 8. The roller-diaphragm combined coupling can synthesize the respective advantages of the roller shaft coupling and the diaphragm shaft coupling, can compensate greater angular displacement and axial displacement, relieve impact and vibration, reduce the stress of a diaphragm, and improve the working condition of a roller, thus prolonging the service life of the coupling.

Description

A kind of roller-membrane combination coupling
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, rolling mill etc.), the coupling arrangement of transmission of power.
Background technique:
The coupling that can compensate angular displacement, axial displacement has gear coupling, ball coupling, diaphragm coupling, polytypes such as universal joint cross coupling.Gear coupling needs good lubricating condition, has the cost height, shortcomings such as compensate for displacement ability.Though ball coupling can big angular displacement, the axial displacement of compensate for slower, exists defectives such as impact resisting vibrating ability.Diaphragm coupling has the mitigation impact shock, generally need not lubricate, be convenient to advantages such as installation and maintenance, but under bigger angular displacement, axial displacement situation, diaphragm bears additional stress, and diaphragm damages easily.The universal joint cross coupling can be regulated bigger angular displacement, but is not suitable for high speed, heavily loaded occasion.A kind of roller-membrane combination coupling is a kind of novel coupler, have and to transmit bigger torque, allow bigger Displacement error, allow high speed rotating, can relax advantage such as impact shock, be widely used in industries such as military affairs, shipbuilding, aviation, petrochemical industry, machinery, metallurgy, can replace coupling arrangements such as gear coupling, rubbercushioned sleeve bearing coupling, ball coupling, diaphragm coupling, universal joint cross coupling.
A kind of roller-membrane combination coupling, it is by external toothing 1, cydariform roller 2, ring gear 17, diaphragm group 11, half-coupling 16 compositions such as grade, its characteristics are, in the serrate slot between external toothing 1 and the ring gear 17 cydariform roller 2 are housed, by external toothing 1, screw 5 and pressing plate 6 restriction cydariform rollers 2 move axially, end cap 4 is fixed on the ring gear 17 by screw 18, compresses seal ring 3, and end cap 15 is fixed on the ring gear 17 by screw 13, compress seal ring 14, diaphragm group 11 is by fixing pin 10, and fixed cover 12 fits together, by bolt 7, nut 8, compression spring 9 are separately fixed on ring gear 17 and the half-coupling 16.
Summary of the invention:
The technical problems to be solved in the utility model is, provide a kind of can the big angle of compensate for slower, axially, radial displacement, reduce the suffered stress of diaphragm, improve the roller operating conditions, improve the coupling in the working life of coupling.
The utility model provides a kind of a kind of roller-membrane combination coupling with following structure for solving above technical problem.It is by external toothing 1, cydariform roller 2, ring gear 17, diaphragm group 11, half-coupling 16 compositions such as grade, its characteristics are, in the serrate slot between external toothing 1 and the ring gear 17 cydariform roller 2 is housed, by external toothing 1, screw 5 and pressing plate 6 restriction cydariform rollers 2 move axially, and end cap 4 is fixed on the ring gear 17 by screw 18, compress seal ring 3, end cap 15 is fixed on the ring gear 17 by screw 13, compresses seal ring 14, and diaphragm group 11 is by fixing pin 10, fixed cover 12 fits together, by bolt 7, nut 8, compression spring 9 are separately fixed on ring gear 17 and the half-coupling 16.
A kind of roller-membrane combination coupling combines the advantage of Roller coupling and diaphragm coupling, the big angle displacement of energy compensate for slower, axial displacement relax impact shock, reduce the suffered stress of diaphragm, improve the roller operating conditions, thereby improve the working life of coupling.
Description of drawings:
Fig. 1---a kind of roller-membrane combination coupler structure schematic representation
Embodiment:
Provide embodiment of the present utility model below in conjunction with accompanying drawing, be used for further specifying technical solution.
With reference to figure 1, find out that by accompanying drawing a kind of roller-membrane combination coupling is by external toothing 1, cydariform roller 2, ring gear 17, diaphragm group 11, half-coupling 16 compositions such as grade, its characteristics are, in the serrate slot between external toothing 1 and the ring gear 17 cydariform roller 2 is housed, by external toothing 1, screw 5 and pressing plate 6 restriction cydariform rollers 2 move axially, and end cap 4 is fixed on the ring gear 17 by screw 18, compress seal ring 3, end cap 15 is fixed on the ring gear 17 by screw 13, compresses seal ring 14, and diaphragm group 11 is by fixing pin 10, fixed cover 12 fits together, by bolt 7, nut 8, compression spring 9 are separately fixed on ring gear 17 and the half-coupling 16.
Moment of torsion is passed on the ring gear 17 through roller 2 by external toothing 1, and through bolt 7, diaphragm group 11 passes to moment of torsion on the half-coupling 16 of opposite side, finishes the transmission of power and motion.Roller 2 is the cydariform roller, is contained in the teeth groove of external toothing 1 and ring gear 17, and this structure allows external toothing 1 and ring gear 17 that certain angular displacement is arranged.The teeth groove of ring gear 17 is long, allows external toothing 1 and ring gear 17 that certain axial displacement is arranged.Diaphragm group 11 is by fixing pin 10, and fixed cover 12 fits together, by bolt 7, and nut 8, compression spring 9 is separately fixed on ring gear and the half-coupling.This structure can either compensate certain angular displacement, axial displacement, has the impact shock of mitigation effect again.End cap 4 is fixed on the ring gear 17 by screw 18, compresses seal ring 3, and end cap 15 is fixed on the ring gear 17 by screw 13, compresses seal ring 14.End cap 4, seal 3, end cap 15, seal 14 is formed Seal cage with ring gear 17, prevents that dust from entering in the tooth cavity of external toothing 1 and ring gear 17 formations, in order to avoid worsen the working condition of roller, the working life of reducing coupling.
