The characteristic of the diaphragm coupling is a bit like a bellows coupling, in fact the way the coupling transmits torque is similar.
The diaphragm coupling adopts austenitic stainless steel diaphragm, which can withstand large deformations while transmitting torsion, thereby compensating for the misalignment of the two shafts.
Compared with gear couplings, diaphragm couplings have no relative sliding, no lubrication, sealing, no noise, basically no maintenance, and more convenient manufacturing.
Applying predictable low additional load to the connected device Compared with similar flexible transmission elements, the diaphragm coupling exerts a predictable small force and bending moment on the connected device.
Allowable high torque-is the large critical value for the damage of the diaphragm coupling during use.
The diaphragm coupling can actively compensate for the axial, radial and angular offset caused by the motor, as well as the influence caused by factors such as manufacturing errors, installation errors, bearing deformation and temperature rise.
The projection of the movable end face circle of the motor on the fixed end face is approximately regarded as a perfect circle, because the distance from the movable end to the fixed end face remains unchanged.
The diaphragm group is the main elastic element of the diaphragm coupling.During operation, the diaphragm group is subjected to complex forces such as stretching, squeezing, and shearing, and is in a complex state of force, and thus transmits torque and motion, while absorbing vibration and compensating for deviation.
