Advantages and structure of diaphragm coupling

Diaphragm couplingCompared with the gear coupling, there is no relative sliding, no lubrication, sealing, no noise, basically no maintenance, easy to manufacture, and can partially replace the gear coupling.Diaphragm couplings are common in developed countries in the world. Machinery industry standards have been formulated in our country, and *recently, they have been revised as new industry standards: JB/T 9147-1999 (instead of ZB/T J19022-90). The relationship between the torques of the shaft.

DiaphragmCouplingIt is composed 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 others 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.
