JMⅠ basic diaphragm coupling with counterbore
Summary:The JMⅠ basic diaphragm coupling with counterbore 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 free from temperature and oil pollution. It has the characteristics of acid resistance, alkali resistance and corrosion resistance.
The JMⅠ basic diaphragm coupling with counterbore 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 free from temperature and oil pollution. It has the characteristics of acid resistance, alkali resistance and corrosion resistance.Compared with the gear coupling, there is no relative sliding, no lubrication, sealing, no noise, basically no maintenance, more convenient to manufacture, and can partially replace the gear coupling.
The JM Ⅰ basic diaphragm coupling with counterbore produced by our company is suitable for shafting transmission in high temperature, high speed, and corrosive medium working conditions. It is 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 machinery, textile machinery, chemical machinery, mining machinery, metallurgical machinery, aviation (helicopters), naval high-speed power transmission system, after dynamic balance It has been widely used in high-speed transmission shaft systems.
