●JMI type basic type with counterboreDiaphragm couplingIt is a high-performance flexible coupling with metal elastic elements. It does not require lubrication, has a compact structure, has a long service life, has no rotation gap, and is not affected by temperature and oil. It has the characteristics of acid, alkali, and high temperature resistance , High-speed, corrosive medium working conditions, shafting transmission, widely used in shaft transmission of various mechanical devices, such as water pumps (especially high-power, chemical pumps), fans, compressors, hydraulic machinery, petroleum machinery, printing High-speed power transmission systems of machinery, textile machinery, chemical machinery, mining machinery, metallurgical machinery, aviation (helicopters), and naval vessels are commonly used in high-speed drive shaft systems after dynamic balance.
●Compared with gear coupling, JMI type diaphragm coupling with counterbore has no relative sliding, does not require lubrication, sealing, noise, basically does not require maintenance, and is more convenient to manufacture. It can partially replace gear couplings. Device.Diaphragm couplings have been widely used in the industrially developed industry. In practical applications, the intermediate shaft type is generally used to improve the performance of two-axis offset compensation.
