The coupling diaphragm is made up of several groups of diaphragm (stainless steel thin spanner) and bolts are interlaced with two semi shaft couplings. Each diaphragm is made up of several sheets. The diaphragm is divided into connecting rod type and whole shape with different shapes.
By the elastic deformation of diaphragm coupling diaphragm to compensate the relative displacement of the two connected axles, is a high performance metal elastic element of flexible coupling, no lubrication, compact structure, high strength, long service life, no rotation clearance, not affected by temperature and oil, has the characteristics of acid resistance and alkali resistance, corrosion resistance. Suitable for high temperature and high speed, the drive shaft corrosion conditions, widely used in various mechanical shaft drive device, such as pumps (especially large power, chemical pump), blower, compressor, hydraulic machinery, petroleum machinery, printing machinery, textile machinery, chemical machinery, mining machinery, metallurgical machinery, aviation (helicopters and naval vessels) high speed power transmission system, the dynamic balance is applied to the high-speed transmission shaft is prevalent.
Heavy machinery with diaphragm coupling has high mechanical strength, large bearing capacity, light weight, small size, transmission efficiency and high precision, good reliability, convenient assembly and disassembly, and has no relative sliding, no lubrication, long service life, no noise, acid and alkali resistance, corrosion resistance, can be used for high temperature at low temperature, and oil, water and corrosive conditions. It is suitable for middle, high speed and large torque shafting transmission. As well as the shafting transmission with little change in the load of various mechanical devices, it is very versatile.
First, before installation, we should clean the end face of two axes and check the cooperation of the end of the end bond.Second, after installation of diaphragm couplings, all the screws must be checked if a class is normally operated. If we find loosening, we must tighten it up, so we can repeat several classes to ensure that it will not loose.Third, in order to prevent the fretting wear of the diaphragm from running at high speed, resulting in the micro cracks of the bolt holes, the diaphragm can be coated with solid lubricant such as molybdenum disulfide or wear reducing coating on the surface of the diaphragm.Fourth, the occurrence of overloading and operation of the accident should be avoided.Fifth, During the work operation, it is necessary to check the abnormal phenomenon of the diaphragm coupling, such as the abnormal phenomenon and the maintenance.Sixth, appropriate safety measures must be taken in every site that may cause the accident of personal and equipment accidents due to diaphragm coupling.
