Each group diaphragm membrane coupling set by the number of pieces stacked together, the diaphragm is divided into different shapes-link and the entire piece. SJM diaphragm coupling by elastic deformation of the diaphragm to compensate for the relative displacement of the two axes Union, is a high performance metal elastic element flexible coupling. SJM diaphragm coupling high mechanical strength, high load capacity, light weight, small size structure, high transmission efficiency and accuracy, reliability, easy assembly and disassembly, and possessed with or without sliding, no lubrication, long life, no noise, acid, corrosion and other characteristics, diaphragm couplings can be used for high temperature, low temperature and oil, water and corrosive environmental conditions. Diaphragm couplings whole model specification, suitable for medium and high-speed, high torque shaft drive and a variety of mechanical devices shaft drive loads of little change, highly versatile. Botou Jie Thai Machinery Manufacturing diaphragm couplings, the choice of qualified material, in accordance with product quality standards and design process, the application of advanced manufacturing equipment, the product of self and mutual inspection and after each session, the cost savings to customers, improve work efficiency.
