JMⅡ type non-counterbore basic diaphragm coupling
Summary:The JMⅡ type non-counterbore basic diaphragm coupling is composed of several groups of diaphragms (stainless steel thin plate) which are alternately connected with two halves of the coupling with bolts. Each group of diaphragms is formed by stacking several pieces. The diaphragm is divided into two groups. It is a connecting rod type and a whole piece type of different shapes.
The JMⅡ type non-counterbore basic diaphragm coupling is composed of several groups of diaphragms (stainless steel thin plate) which are alternately connected with two halves of the coupling with bolts. Each group of diaphragms is made up of several pieces. The diaphragm is divided into two groups. It is a connecting rod type and a whole piece type of different shapes.Its elastic deformation compensates 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, has a compact structure, high strength, long service life, no rotation gap, and is not subject to temperature. It has the characteristics of acid resistance, alkali resistance and corrosion resistance.
JMⅡ type non-counterbore basic diaphragm coupling is 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, which are applied to high-speed transmission after dynamic balance Shafting has become more common.
