Diaphragm couplingOften used in servo systems, the diaphragm has good torque rigidity, but it is slightly inferior to the bellows coupling.
2. The diaphragm coupling is composed of at least one diaphragm and two shaft sleeves.The diaphragm is fastened to the shaft sleeve by a pin and generally does not loosen or cause backlash between the diaphragm and the shaft sleeve.
3. The initially selected coupling size of the bearing coupling, that is, the diameter of the shaft hole and the length of the shaft hole, should meet the requirements of the shaft diameter of the driving and driven ends, otherwise the coupling specifications must be adjusted according to the shaft diameter.
4. The characteristic of 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. Withstand deviations of up to 1.5 degrees, while generating lower bearing loads in the servo system.
5. On the other hand, the diaphragm coupling is very delicate, and it can be easily damaged 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.
