Abstract
The utility model relates to a connecting component in the mechanical transmission field, in particular to a torque-adjusted coupling. A sleeve is provided with a plate-type sprocket wheel. An annular paired sprocket wheel is arranged between the driven sprocket wheel and the plate-type sprocket wheel. A frictional piece A is arranged between the plate-type sprocket wheel and the sleeve, and a frictional piece B is arranged between the plate-type sprocket wheel and a hold-down plate. A buffered element is arranged between the hold-down plate and a guidance plate. The outer side of the guidance plate is connected with an adjusting element positioned on the sleeve. The frictional piece A, the frictional piece B, the plate-type sprocket wheel, the hold-down plate, the buffered plate and the guidance plate are connected with sleeve. A overload protection is shaped between the working machine and the priming engine so that the occurred failure cannot cause the damages to the components, therefore, the components easily damaged need not to be displaced, which not only protects the safe and reliable operation for the equipment, but also improves the working efficiency, thereby being usable for the overload protection for the changed load in the chemical industry, the light industry and architectural machineries.
Description
Technical field:
The utility model relates to the connected element of mechanical transmission fields, relates in particular to a kind of coupling.
Background technique:
The kind of coupling is a lot, be widely used in papermaking, glass, rubber and other chemical industry, in light industry and the building machinery field, but change in torque takes place in coupling at work sometimes, if between working machine and prime mover, do not have overload protection, burn out drive motor easily, so safety coupling just arises at the historic moment, in mechanical design handbook, introduce a kind of safe pin coupling is arranged, as load-carrying unit, when work loads surpassed allowable value, straight pin was cut off automatically with straight pin, thereby cut off the transmission between working machine and prime mover, can play overload protective function, but, recover to reinstall straight pin before the transmission owing to be to be rigidly connected; Since too responsive to the moment overload, so cause the unnecessary damage of straight pin easily; When limiting the moment of torsion change, need to change corresponding straight pin, the operation trouble wastes time again, uses very inconvenient.
Summary of the invention:
The utility model provides a kind of torque adjustable coupling at above deficiency exactly, between working machine and prime mover, form overload protection, transferable torque is demarcated in advance to coupling, when load strengthens, produces skidding between two shaft couplings automatically; In case load reduces, can recover the synchronous rotation between two shaft couplings again automatically.
The technical solution adopted in the utility model is:
The adjustable coupling of a kind of torque is included in the driven sprocket of working machine input shaft connection, the sleeve that connects on driving motor, also be connected with board-like sprocket wheel on its middle sleeve, driven sprocket and board-like sprocket wheel are socketed with double strand chain, has friction plate A between board-like sprocket wheel and the sleeve, has friction plate B between board-like sprocket wheel and the pressing plate, shock absorber is located between pressing plate and the guide plate, and the fixedly connected adjustment piece of the outside of guide plate and sleeve is connected.
Board-like sprocket wheel, pressing plate, guide plate all are socketed on the sleeve.
Also be provided with axle sleeve between board-like sprocket wheel and the sleeve.
Shock absorber adopts butterfly spring.
Adjustment piece comprises adjusting screw and adjusting nut, and adjusting screw is by adjusting nut and guide plate apical grafting.
The beneficial effect that the utility model can reach is:
1, the utility model adopts double strand chain to connect two sprocket wheels, changes the moment of demarcating by adjustable variation in pressure between two friction plates and board-like sprocket wheel, forms overload protection between working machine and prime mover.
2, the utility model adopts friction to connect, and the Shi Buhui that breaks down causes component wear, therefore needn't change easily damaged parts, has both improved the safety reliability of equipment operation, has improved working efficiency again.
3, the utility model has adopted shock absorber, has alleviated startup effectively, has stopped the impulsive load with transmission process, has guaranteed the accuracy of demarcating.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
The utility model will be further described below in conjunction with accompanying drawing:
As shown in Figure 1, the utility model comprises the driven sprocket 1 that connects with the working machine input shaft, the sleeve 2 that on driving motor, connects, on sleeve 2, also be set with board-like sprocket wheel 11, between driven sprocket 1 and board-like sprocket wheel 11, be set with annular double strand chain 3, has A friction plate 4 between board-like sprocket wheel 11 and the sleeve 2, has B friction plate 10 between board-like sprocket wheel 11 and the pressing plate, shock absorber 6 is located between pressing plate 5 and the guide plate 9, the outside of guide plate 9 is connected A friction plate 4 with adjustment piece on being installed in sleeve 2, B friction plate 10, board-like sprocket wheel 11, pressing plate 5, shock absorber 6, guide plate 9 all is socketed on the sleeve 2.Also be provided with axle sleeve between board-like sprocket wheel 11 and the sleeve 2.Shock absorber 6 adopts butterfly spring.The outside of described guide plate 9 is meant is fixed with adjusting nut 8 on sleeve 2 with being installed in adjustment piece apical grafting on the sleeve 2, and adjusting screw 7 is installed on adjusting nut 8, and the screw-thread fit by adjusting screw and adjusting nut holds out against guide plate with adjusting screw.
The adjustable coupling of this torque is included in the driven sprocket 1 of working machine input shaft connection, the sleeve 2 that connects on driving motor, wherein on sleeve 2, be set with A friction plate 4, board-like sprocket wheel 11, B friction plate 10, pressing plate 5, butterfly spring 6 and guide plate 9 successively, guide plate 9 and adjusting screw 7 apical graftings that pass through adjusting nut 8, driven sprocket and board-like sprocket wheel are socketed with double strand chain 3, also are provided with axle sleeve between board-like sprocket wheel 11 and the sleeve 2.
Before the adjustable coupling of this torque is installed, torque request according to working machine, by regulating the gap between guide plate and the nut, change the pressure of disk spring to friction plate, thereby change the frictional force between two friction plates and the board-like sprocket wheel, demarcate the good berth torque, then it is installed between driving motor and the working machine.When torque that operation torque is set less than us, the friction torque that board-like sprocket wheel bi-side produce is greater than operation torque, the friction torque of driving motor by producing between sleeve, pressing plate, two friction plates and board-like sprocket wheel, by the double strand chain that is enclosed within on two sprocket wheels, transmission of power is arrived the working machine part; When torque that operation torque is set greater than us; to produce relative skidding between board-like sprocket wheel and two friction plates; make the relative leaf chain wheel of the sleeve idle running of driving motor; thereby cut off the transmission between driving motor and the working machine; protected the safety of drive motor; when can be used in chemical industry, light industry, the building machinery load variations, to the overload protection of prime mover.
