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 keyway flange diaphragm coupling relies on the elastic deformation of the diaphragm to compensate for the relative displacement of the connected two shafts. It is a high-performance flexible coupling with metal elastic elements. It does not require lubrication, and has a compact structure and high strength. Long life, no rotation gap, not affected by temperature and oil pollution.
The high-speed diaphragm coupling is composed of several groups of diaphragms (stainless steel thin plates) which are interlaced with the two halves of the coupling with bolts. Each group of diaphragms is made up of several pieces. The diaphragms are divided into rod type and different shapes. Whole piece.
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".
