Features of diaphragm coupling

Diaphragm couplingThis characteristic is a bit like a bellows coupling, in fact the way the coupling transmits torque is similar.The diaphragm itself is very thin, so it is easy to bend when the relative displacement load is generated, so it can withstand up to 1.5 degrees of deviation, while generating a lower bearing load in the servo system.Diaphragm couplings are often used in servo systems. Diaphragms have good torque rigidity, but are slightly inferior to bellows couplings.On the other hand, the diaphragm coupling is very delicate and can be easily damaged if it is misused in use or not installed correctly.Therefore, it is very necessary to ensure that the deviation is within the tolerance range of the normal operation of the coupling.Choosing the right coupling is a key step to make good use of the coupling. In the design stage, you have to consider what type of coupling to choose.Compared with the gear coupling, the diaphragm coupling has no relative sliding, no lubrication, sealing, no noise, basically no maintenance, easy to manufacture, and can partially replace the gear coupling.Diaphragm couplings are common in developed countries in the world. Machinery industry standards have been formulated in our country, and *recently, they have been revised as new industry standards: JB/T 9147-1999 (instead of ZB/T J19022-90).
