DJM type expansion sleeve diaphragm coupling
Main features of DJM type expansion sleeve diaphragm coupling:
1. The allowable range of eccentricity is large and can be flexibly applied to various transmission systems.
2. Disassembly and assembly are of high importance for assembly.
3. Good environmental adaptability, can operate at high temperature.
4. Simple structure and light weight.
5. No maintenance is required, and faults can be checked with the naked eye when shutting down.
6. No lubrication, no noise and wear.There are no sliding, friction, or rotating parts, which can reduce energy loss.
7. High transmission accuracy.High sex and long life.
DJM type expansion sleeve coupling elastic diaphragm coupling 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 systems, steam turbines, piston-type power mechanical transmission systems, crawler vehicles, and high-speed, high-power mechanical transmission systems of generator sets, After being dynamically balanced, it is relatively common to apply to high-speed transmission shafting.
