The correct choice of diaphragm coupling has the following points:
1, The diaphragm coupling is composed of at least one diaphragm and two sleeves. The diaphragm is fastened to the sleeve with a pin and generally will not loose or cause backlash between the diaphragm and the sleeve. There are some productions The supplier provides two diaphragms, and also provides three diaphragms, with one or two rigid elements in the middle, and the two sides are connected to the shaft sleeve.
2, 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 itself is very thin, so it is easy to bend when the relative displacement load is generated, so it can withstand Deviations of up to 1.5 degrees, while generating lower bearing loads in the servo system. 
3. Diaphragm couplings are often used in servo systems. Diaphragms have good torque rigidity, but are slightly inferior to bellows couplings. 
4. Choosing a suitable 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. 
5. On the other hand, the diaphragm coupling is very delicate, and it is easy to damage if it is misused or not installed correctly during use. Therefore, it is very necessary to ensure that the deviation is within the tolerance range of the normal operation of the coupling.
