JMⅡ diaphragm coupling

description: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.

Detailed introduction:

JMⅡ diaphragm couplingDiaphragm couplings belonging to the JM series are composed of several groups of diaphragms (stainless steel thin plates) that are alternately connected to the two halves of the coupling with bolts. Each group of diaphragms is composed of several pieces stacked together. The diaphragms are divided into Rod type and different shapes of the whole piece type.Its elastic deformation compensates for the relative displacement of the connected two shafts. It is a high-performance flexible coupling with metal elastic elements.No need for lubrication, compact structure, long service life, no rotation gap, not affected by temperature and oil pollution, and has the characteristics of acid resistance, alkali resistance, and corrosion resistance.

JMⅡDiaphragm couplingIt is a common diaphragm coupling suitable for shafting transmission in high temperature, high speed, and corrosive medium conditions. It is widely used for shafting transmission of various mechanical devices, such as water pumps (especially high-power, chemical pumps), Fans, compressors, hydraulic machinery, petroleum machinery, printing machinery, textile machinery, chemical machinery, mining machinery, metallurgical machinery, aviation (helicopters), naval high-speed power transmission systems, after being dynamically balanced, are applied to high-speed transmission shaft systems.
