The diaphragm coupling 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.
The JMⅡ diaphragm coupling belongs to the JM series of diaphragm couplings. It is composed of several groups of diaphragms (stainless steel thin plate) that are alternately connected with two halves of the coupling with bolts. Each group of diaphragms is made up of several pieces. , Diaphragm is divided into connecting rod type and whole piece type of different shapes.
The JMⅡJ diaphragm coupling has a strong ability to compensate for the misalignment of the two axes. Compared with the gear coupling, the angular displacement can be doubled, the reaction force is small in the radial displacement, the flexibility is large, and some axial and radial directions are allowed. And angular displacement. The JMⅡJ diaphragm coupling is different from the ordinary diaphragm coupling. It is not only connected with an intermediate shaft to extend the transmission distance, but also equipped with two diaphragms to increase the amount of flexibility compensation, so it is also called a double diaphragm coupling.
The DJM expansion sleeve diaphragm coupling compensates the relative displacement of the two shafts connected by the elastic deformation of the diaphragm. The diaphragm is divided into a connecting rod type and an integral type.The structure is composed of several sets of diaphragms that are alternately connected with the two halves of the coupling by bolts. The ordinary diaphragm coupling and the drive shaft are connected by a keyway, while the DJM type expansion sleeve diaphragm coupling is through an additional The taper sleeve is connected with the drive shaft, so it is also called "taper sleeve type elastic diaphragm coupling".
