Diaphragm type coupling
Diaphragm Couplings This feature is a bit like a bellows coupling. In fact, the coupling transmits torque in much the same way. The diaphragm itself is very thin, so it is easy to bend when generated by relative displacement loads, so it can withstand deviations of up to 1.5 degrees while producing lower bearing loads in the servo system. Diaphragms Couplings are commonly used in servo systems where the diaphragm has good torque rigidity but is still slightly inferior to the bellows coupling. On the other hand, the diaphragm coupling is very delicate and can be easily damaged if it is misused or not properly installed. The diaphragm coupling is easy to use, so it is necessary to ensure that the deviation is within the normal operating range of the coupling. Choosing the right coupling is a key step in using the coupling. It is important to consider what type of coupling to use during the design phase.
Compared with the toothed coupling, the diaphragm coupling has no relative sliding, no lubrication, no sealing, no noise, no maintenance, and is easy to manufacture. It can partially replace the gear coupling. Diaphragm couplings have been widely used in industrialized countries in the world. Machinery industry standards have been formulated in China, and new industry standards have been revised: JB/T 9147-1999 (instead of ZB/T J19022-90) Couplings The relationship between torques.
