Coupling diaphragm

Diaphragm coupling byCoupling diaphragmIt is a kind of high-performance flexible coupling with strong metal components. It does not need lubricating oil, has a compact structure, high strength, long service life, no rotation gap, and is not subject to temperature. And oil pollution, suitable for shafting transmission in high temperature, high speed, and corrosive environment

Coupling diaphragm product structure

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.

Coupling diaphragm product features

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.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 important to ensure that the deviation is within the tolerance range of the normal operation of the coupling.Choosing a suitable coupling is a key step to make good use of the coupling. You have to consider what type of coupling to choose in the design stage.
