THE DIAPHRAGM COUPLING MOVES AXIALLY TO THE WORKING POSITION

When installing the diaphragm coupling, pay attention to aligning the concentricity of the two shafts. Before installation, check whether the diaphragm elastic coupling has been damaged during transportation.During the installation process of the disc couplings, the parts should be properly lifted or supported, and the surface of the disc elastic couplings should be properly packaged. In particular, the flange and stop should be protected from scratches and burrs. Check whether there are defects such as bruises, cracks, excessive deformation and other defects on the outer surface of the diaphragm group of the disc coupling. If it exists, it should be replaced in time.

When the shaft hole fit of the elastic disc couplings is a clearance fit, you can directly install the hub on the shaft, and tap the half coupling with a soft hammer. For example, the shaft hole fit of the diaphragm elastic coupling is If there is an interference fit, the hub needs to be heated before installation.The hub of the diaphragm coupling moves axially to its working position, and the distance moved from the starting position to the working position is called the axial advancement value. Sometimes in order to achieve the desired interference value, the hub can be heated.
