The diaphragm coupling relies on the elastic deformation of the diaphragm to compensate for the relative displacement of the two shafts connected. It is a high-performance flexible coupling with metal elastic elements. It does not require lubrication, has a compact structure, high strength and long service life. No rotation gap, not affected by temperature and oil pollution, with acid resistance, alkali resistance, and corrosion resistance. It is suitable for shafting transmission in high temperature, high speed, and corrosive medium working conditions. It is widely used for shafting 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 (helicopter), high-speed power transmission of ships The system, after being dynamically balanced, is commonly used in high-speed transmission shafts.

Diaphragm couplings For flexible and toothed couplings, some are lubricated with grease.That is, when the coupling is working, it can be lubricated due to the squeeze of grease.When assembling, grease is applied to ensure that there is sufficient lubrication inside.The grease used in high-speed devices must ensure that the oil and soap do not separate under the action of centrifugal force, otherwise the coupling oil leakage will reduce the lubrication effect.At the same time, multi-efficiency is required, that is, heat resistance and a certain degree of cold resistance when working at low temperatures.The lubrication of spring-type couplings mostly uses grease.When assembling, the grease must fill the gap between the grids and be wrapped up to prevent grease leakage.Regular inspections are required during work, and extreme pressure lithium grease is generally used for refilling grease.
