Coupling diaphragm

Compared with the gear coupling, the diaphragm of the coupling has no relative sliding, no lubrication, sealing, no noise, basically no maintenance, easy to manufacture, and can partially replace the gear coupling.

The coupling diaphragm consists of at least one diaphragm and two shaft sleeves.The diaphragm is fastened to the shaft sleeve with a pin and generally does not loosen or cause backlash between the diaphragm and the shaft sleeve.Some manufacturers provide two diaphragms, and some provide three diaphragms, with one or two rigid elements in the middle, and the two sides are connected to the shaft sleeve.The difference between the single diaphragm coupling and the double diaphragm coupling is the ability to handle various deviations. In view of the complex bending of the diaphragm, the single diaphragm coupling is not suitable for eccentricity.The double diaphragm coupling can bend in different directions at the same time to compensate for eccentricity.

The characteristic of the coupling diaphragm 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.
