The diaphragm coupling is composed of a 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.
The difference between the double diaphragm coupling and the single 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, while the double diaphragm coupling The piece coupling can be bent in different directions at the same time to compensate for eccentricity.
The function of the double diaphragm is to adjust the centering deviation of the installation shaft, such as angular deviation, parallel deviation and axial deviation.The single diaphragm coupling does not have the ability to adapt to parallel deviation, while the double diaphragm can.In addition, there is a difference between a heavy-duty and a light-duty double diaphragm, and the light-duty type is generally used in precision motion control.
