Product Details

JZMJ type heavy machineryDiaphragm couplingIt is composed of several groups of diaphragms (stainless steel thin plate) which are connected with two halves of the coupling in a staggered manner with bolts. Each group of diaphragms is composed of several stacked ones. The diaphragms are divided into connecting rod type and whole piece type of different shapes.

The JZMJ diaphragm coupling for heavy machinery is a flexible coupling with metal elastic elements. It does not need lubrication, has a compact structure, has a long service life, has no rotation gap, is not affected by temperature and oil, and is acid and oil resistant. The characteristics of alkali, suitable for high-temperature, high-speed, and corrosive medium shafting environment.

JZMJ diaphragm couplings for heavy machinery are 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, textiles High-speed power transmission systems of machinery, chemical machinery, mining machinery, metallurgical machinery, aviation (helicopters), and naval vessels are commonly used in high-speed transmission shaft systems after being dynamically balanced.

JZMJ type diaphragm coupling device for heavy machinery has large load capacity, light weight, small structure size, transmission efficiency and transmission, good performance, convenient assembly and disassembly, and has no relative sliding, no lubrication, slip, and long service life , No noise, acid and alkali resistance, etc., can be used in high temperature, low temperature, oil, water and corrosive media working environment.Suitable for medium, high speed and large torque shaft transmission.As well as various mechanical devices, shaft transmission with little change in load, versatility.
