     Causes of damage to the drum gear coupling:
    1. When using couplings, the equipment in the shafting system, such as diesel engines, gearboxes, shafting and high-elastic couplings, must complement each other in design and use, and the level of design and manufacturing is relatively high. , The quality of the ship designed in this way is also very high.
    2. The main reason is that the vibration damper of the main engine has sunk, which makes the shafting of the coupling appear asymmetry, thereby increasing the additional torque, which makes the highly elastic coupling in use When there is a breakage accident due to fever.
    3. Because the use range of couplings is relatively wide, they are widely used in many industries.It may be improperly used in specific situations, or it may be used without consideration, which will also cause the coupling to be damaged during use.
    Drum-shaped gear couplings are rigid, flexible, and inelastic, so they are not suitable for machinery that requires damping, cushioning, and two-axis alignment.
    1. Strong carrying capacity.Under the same outer diameter of the inner gear sleeve and the maximum outer diameter of the coupling, the carrying capacity of the drum gear coupling is on average 15-20% higher than that of the straight gear coupling.
    2. The tooth end of the outer gear sleeve is in the shape of a horn, which makes the assembly and disassembly of the inner and outer teeth very convenient.
    3. The transmission efficiency is as high as 99.7%.
    4. The drum-shaped tooth surface improves the contact conditions of the inner and outer teeth, avoids the disadvantages of spur tooth end edge extrusion and stress concentration under the condition of angular displacement, and at the same time improves the friction and wear of the tooth surface, and reduces Noise, long maintenance period.
    5. Large angular displacement compensation.When the radial displacement is equal to zero, the allowable angular displacement of the spur gear coupling is 1º, and the allowable angular displacement of the drum gear coupling is 1º30, which is increased by 50%. When wide, the angular displacement of the drum-shaped gear is larger than that of the straight tooth.
    Couplings are 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 generator sets high-speed, high-power mechanical transmission systems, which are applied to high-speed transmission shafts after dynamic balance Has become more common.The diaphragm coupling is composed of at least one diaphragm and two shaft sleeves.The diaphragm is fastened to the shaft sleeve with a pin and generally does not loosen or cause backlash between the diaphragm and the shaft sleeve.Some manufacturers provide two diaphragms, and others provide three diaphragms, with one or two rigid elements in the middle, and the two sides are connected to the shaft sleeve.
