Description

Magnetic composite diaphragm coupling

Technical Field

The utility model relates to a shaft coupling.

Background

The diaphragm coupling transmits torque by shearing force of the bolt. The stressed diameter of each bolt is fixed, so that the transmission torque of the coupling with the same specification is limited. Meanwhile, due to factors such as starting, installation and use conditions and the like, the diaphragm coupler is overloaded and bears impact force, and the rated torque of the unit is greater than that of the coupler, so that unstable starting, and the conditions of diaphragm tearing and bolt breakage are easily caused.

SUMMERY OF THE UTILITY MODEL

The utility model discloses an improve to prior art diaphragm coupling's not enough, provide one kind and start the stationarity good, the transmission vibration is little, and anti overload damage ability is strong, the big magnetic force composite diaphragm coupling of transmission moment of torsion.

The utility model discloses a magnetic force composite diaphragm coupling, which comprises an input end half coupling, a middle coupling, an output end half coupling, a diaphragm component, a compensation cushion block, a driving bolt and a nut; the flange end plate of the input end shaft coupling and the flange end plate of the middle coupling and the flange end plate of the output end shaft coupling and the flange end plate of the middle coupling are respectively connected by the membrane assembly, the compensating cushion block, the driving bolt and the nut in a matching way, and the device is characterized in that:

the flange end plate of the input end half coupling and the flange end plate of the output end half coupling are respectively fixedly connected with an L-shaped outer sleeve through screws, the inner annular surface of the L-shaped outer sleeve is provided with a circular groove, and an outer magnetic steel block is fixedly arranged in the circular groove;

the outer circular surfaces of the left end flange end disc of the middle section and the right end flange end disc of the middle section are provided with circular ring grooves, inner magnetic steel blocks are fixedly arranged in the circular ring grooves, and the outer magnetic steel blocks are correspondingly matched with the inner magnetic steel blocks;

the driving bolt holes on the left end flange end disc of the middle section and the right end flange end disc of the middle section are circular arc-shaped slotted holes.

The utility model discloses during operation, because the drive bolt hole on the left end flange end disc of middle section and the right-hand member flange end disc of middle section is the circular arc groove hole, when starting shaft coupling operation transmission like this, middle section and input semi-axis festival and output semi-axis festival can take place certain relative rotational displacement, the outer magnetic steel piece on the L shape overcoat on input semi-axis festival and the output semi-axis festival produces mutual magnetic attraction effect transmission torque with the interior magnetic steel piece on the flange of middle section, make the shaft coupling realize the soft start of elasticity like this, and play the elastic cushioning effect to the rotational vibration of input, output shaft, the speed change impact of reducing speed in operation; meanwhile, the transmission torque can be improved through magnetic transmission, the sizes of the driving bolt and the diaphragm can be relatively reduced, or the transmission torque is improved, so that the stable operation of the diaphragm coupling is facilitated; when the mutual attraction of the outer magnetic steel block and the inner magnetic steel block reaches the maximum, the driving bolt is gradually stressed, and when the unit is stable and fully loaded, the driving bolt and the magnetic transmission simultaneously transmit torque.

The utility model discloses simple structure, it is simple and convenient to make, the instantaneous shearing force that the drive bolt received when reducible start to effectively prevent drive bolt fatigue fracture, its L shape overcoat can also effectually play the effect of protection membrane piece subassembly, prevents that membrane piece subassembly in use from tearing the departure, is particularly suitable for using under the environmental nature that the operating mode produced the change or use under inverter motor.
