    GCLD type drum gear coupling

    Product introduction:

     When the drum gear coupling is working, the two shafts produce relative angular displacement, and the tooth surfaces of the inner and outer teeth periodically slide relative to each other in the axial direction, which will inevitably cause tooth surface wear and power consumption. Therefore, the gear coupling needs to be Work in a good and sealed state.Gear couplings have small radial dimensions and large load-bearing capacity. They are often used in shafting transmissions under low-speed and heavy-duty conditions. High-precision and dynamically balanced gear couplings can be used for high-speed transmissions, such as gas turbine shafting. transmission.Because the angular compensation of drum gear couplings is greater than that of straight gear couplings, drum gear couplings are widely used at home and abroad.

     

    The characteristics of the drum gear coupling: the drum gear coupling has strong load-bearing capacity and high transmission efficiency. Under the same outer diameter of the inner gear sleeve and the maximum outer diameter of the coupling, the load of the drum gear coupling The average capacity is 15-20% higher than that of the straight gear coupling, and the transmission efficiency of the drum gear coupling is as high as 99.7%.The angular displacement compensation of the drum-shaped gear coupling is large.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', an increase of 50%.Under the same modulus, number of teeth, and tooth width of the drum gear coupling, the allowable angular displacement of the drum gear is larger than that of the straight tooth. The drum tooth surface improves the contact conditions of the inner and outer teeth and avoids the angular displacement. Under the condition of displacement, the edge of the straight tooth is squeezed and the stress is concentrated. At the same time, it improves the friction and wear of the tooth surface, reduces the noise, and has a long maintenance period. Dismantling is very convenient,

    The drum gear coupling is a rigid-flexible coupling. The gear coupling is composed of an internal gear ring with the same number of teeth and a flange half coupling with external teeth.The external teeth are divided into straight teeth and drum teeth. The so-called drum teeth means that the external teeth are made into a spherical surface. The center of the spherical surface is on the gear axis. The tooth side clearance is larger than that of ordinary gears. The drum-shaped tooth coupling can Allows a larger angular displacement (compared to the straight tooth coupling), which can improve the contact conditions of the teeth, increase the torque transmission capacity, and prolong the service life.The contact state along the tooth width when there is angular displacement.It has the ability to compensate for axis deviation in radial, axial and angular directions. It has the advantages of compact structure, small turning radius, large carrying capacity, high transmission efficiency, low noise and long maintenance cycle. It is especially suitable for low-speed and heavy-duty conditions, such as Metallurgy, mining, lifting and transportation industries, and also suitable for shafting transmission of various machinery such as petroleum, chemical industry, general machinery, etc.
