Description
The utility model relates to the universal component of mechanical transmission fields, particularly coupling.
Safety coupling mainly is a shear pin formula safety coupling at present, and its structure is by the shear pin transmitting torque.When transmitting torque surpassed certain value, shear pin was cut off, and coupling disconnects the transmission contact, and driving component is protected.Mainly there is the defective of three aspects in present this coupling: 1, rigid joint, once destructive the use.2, too responsive to the moment overload, cause the unnecessary damage of shear pin.3, need the easily damaged parts that more renews after fixing a breakdown.When 4, limiting the moment of torsion change, need to change corresponding shear pin.
The purpose of this utility model provides does not a kind ofly have component wear, can avoid component wear that momentary overload brings, need not to change easily damaged parts and be applicable to the intelligent and safe coupling of different qualification moments of torsion.
The purpose of this utility model is achieved in that the utility model comprises input end, interior friction plate, outside friction disc, output terminal, clamping piston, sensor and controller.There is a shaft shoulder at the input end middle part, and the shaft shoulder outside is a splined shaft.Interior friction plate and outside friction disc are sleeved on the splined shaft of input end successively, and wherein interior friction plate external diameter is the cylndrical surface, and endoporus is a splined hole, and this splined hole cooperates with the splined shaft of input end; The outside friction disc endoporus is the cylndrical surface, and its aperture is greater than the big footpath of input end splined shaft, and external diameter is external splines (being equivalent to splined shaft).The end of output terminal is provided with splined hole, and this splined hole matches with the external splines of outside friction disc, and the path of splined hole is greater than the external diameter of interior friction plate; In this splined hole inboard cylindrical hole is arranged, clamping piston is placed in this cylindrical hole, and cylindrical hole links to each other with compressed pneumatic pump by the through hole in the output terminal.In the groove of the external cylindrical surface of input end and output terminal a magnet steel is housed respectively, with the corresponding position of magnet steel sensor installation respectively, sensor connects controller by electric wire.
During two shaft drive, at first need the cylindrical hole in output terminal to feed pressurized gas, and by clamping piston make in friction plate closely contact with outside friction disc, when input end rotates, driving interior friction plate by its splined shaft rotates, interior friction plate drives outside friction disc by frictional force and rotates thereupon, and outside friction disc drives output terminal by its external splines and rotates.Because adopt friction to connect, the Shi Buhui that breaks down causes component wear.Can carry out intelligent decision by controller to the moment overload, not report to the police when not surpassing specified value.Fault is got rid of the back as long as get final product work by controller by reset button, and need not change easily damaged parts.Can adjust by controller different qualification moments of torsion.
The utility model is described in further detail below by accompanying drawing.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an A-A sectional view among Fig. 1.
See Fig. 1 and Fig. 2, the utility model comprises input end 1, interior friction plate 2, outside friction disc 3, output terminal 4, clamping piston 5, sensor 7 and controller.There is a shaft shoulder at input end 1 middle part, and the shaft shoulder outside is a splined shaft.Interior friction plate 2 and outside friction disc 3 are sleeved on the splined shaft of input end 1 successively, in order to increase frictional force, can be a plurality of in friction plates 2 and outside friction disc 3 alternately be sleeved on the splined shaft of input end 1.Wherein interior friction plate 2 external diameters are the cylndrical surface, and endoporus is a splined hole, and this splined hole cooperates with the splined shaft of input end 1; Outside friction disc 3 endoporus are a cylndrical surface, and its aperture is greater than the big footpath of input end 1 splined shaft, and external diameter is external splines (being equivalent to splined shaft).The end of output terminal 4 is provided with splined hole, and the external splines of this splined hole and outside friction disc 3 matches to merge and is sleeved on the external splines of outside friction disc 3, and the path of splined hole is greater than the external diameter of interior friction plate 2; In this splined hole inboard cylindrical hole is arranged, clamping piston 5 is placed in this cylindrical hole, and cylindrical hole links to each other with compressed pneumatic pump by the through hole in the output terminal 4.In the groove of the external cylindrical surface of input end 1 and output terminal 4 magnet steel 6 is housed respectively, with magnet steel 6 corresponding positions sensor installations 7 respectively, sensor 7 connects controller by electric wire.
During operation, at first carry out parameter and set (setting when initial use maybe need be changed parameter) by controller.After parameter is set, " startup " of pressing basis weight controller.After the startup, pressurized air is injected in the cylindrical hole by the through hole in the output terminal 4, produces frictional force between friction plate 2 and the outside friction disc 3 in making, in order to transmitting torque.
During momentary overload, if input end 1 does not surpass permitted value with output terminal 4 speed discrepancies, controller is not reported to the police, the utility model proper functioning.
During overload, interior friction plate 2 and outside friction disc 3 skid, input end 1 produces speed discrepancy with output terminal 4, after the sensor by controller relatively after, when speed discrepancy surpassed permitted value, controller sent alarm signal, alarm equipment alarm, controller instruction simultaneously disconnects pressurized air, and friction plate 2 and outside friction disc 3 are thrown off in making, not transmitting torque.
After the warning, should discharge fault, pending fault " resets " by controller after getting rid of, and the utility model is proper functioning again.
When needing to change moment of torsion, adjust compressed-air actuated pressure, can transmit different moments of torsion by controller.
The utility model is suitable for using in the higher production line of automated procedures that steel rolling production-line, paper production line, rubber production line etc. work continuously.
