JZM type heavy diaphragm coupling bolt is required to adopt the standard hexagonal head hinged hole bolt, it can be according to the hole diameter of the diaphragm group to choose the corresponding bolt type, the length of the bolt can be determined according to the two half coupling flange and the total thickness of the diaphragm group. The bolt shall be made of 45# steel tempered or medium carbon steel, mainly the mechanical properties of the bolt shall be up to the performance class 8.8.

JZM type heavy duty diaphragm coupling is a high performance flexible coupling of metal elastic element, metal elastic element refers to the diaphragm group, the diaphragm group of the coupling is composed of stainless steel sheet. The coupling has the advantages of no lubrication, high strength, compact structure, long service life, no rotation clearance, not affected by oil pollution and temperature, but also alkali resistant, acid resistant, not easy to corrosion characteristics, suitable for high temperature, high speed and corrosive media environment, in order to extend the service life of the coupling, it is recommended to set the shaft deviation within 1/3 of the allowable value. Do not tighten the screws until the mounting shaft is inserted, otherwise it will cause deformation of the coupling. When tightening screws, use a torque wrench. Do not use screws other than those attached. If abnormal sound occurs during operation, please stop operation immediately and check installation accuracy and screw loosening. It is recommended to apply adhesive to the outer surface of the screw after installation and debugging to improve the protection performance. The JZM heavy-duty diaphragm coupling has a very high transmission efficiency of up to 95%. Especially suitable for medium and high speed power transmission.

JZM heavy-duty diaphragm coupling is capable of compensating the axial, radial and angular offset caused by manufacturing errors, installation errors, load deformation and the influence of temperature rise changes between the drivers and the drivers. JZM type heavy diaphragm coupling is a flexible coupling of metal elastic elements, which relies on the metal coupling diaphragm to connect the main and transfer torque from the motor, has the advantages of elastic vibration reduction, no noise, no lubrication, is the replacement of general coupling products.
