ZJM swelling diaphragm couplings production, factory direct wholesale ZJM swelling diaphragm couplings and expansion sets marked as DJMT diaphragm couplings. Diaphragm coupling shafting Transmission: shaft drive usually consists of one or several of the main diaphragm couplings, driven shaft connected together to form shaft drive system to transmit rotation or movement. Diaphragm coupling was mainly due to the motor, reducer and working machine shaft connection, its shaft hole forms, connection type and size depends mainly on the type and size of the connecting shaft, product design generally cylindrical and conical shaft International standard design deep shaft, deep standard for shaft design. Various forms of the metal diaphragm and a series of coupling design in the structural design, the magnitude of the torque transmitted to the diaphragm structure and the hub coupling strength as the basis, to determine specifications metal diaphragm shaft coupling hole range (maximum and minimum shaft hole) and the shaft length of the bore, each specification only one shaft hole length. In other countries, diaphragm coupling diaphragm coupling of enterprises in different standards, specifications are each only a diaphragm coupling shaft hole lengths. As GB/T3852 misleading, causing the diaphragm coupling of each product standard specifications as the shaft hole corresponds to a variety of changes in the length of the shaft hole, the foreign diaphragm couplings standards into our standards when plus a variety of shaft hole length, it seems that the only way be regarded as complete conversion. Diaphragm couplings are widely used in various mechanical devices shaft drive, such as water pumps (especially in high-power, chemical pumps), fans, compressors, hydraulic machinery, petroleum machinery, printing machinery, textile machinery, chemical machinery, mining machinery, metallurgical machinery, aviation (helicopter), ship speed drivetrain, turbine, piston powered mechanical transmission, tracked vehicles, as well as high-speed generators, high power mechanical transmission, high-speed transmission used by the dynamic balance after shafting has been more common. Features: 1, high concentricity, good stability; 2, high sensitivity, large torque; 3, Zero Backlash, easy accessibility; 4, the shaft hole equipped with Z1-type expansion sleeve, can withstand continuous instantaneous braking or stopping; 5, can also be made into a drogue form.
