　　GCLD (GⅡCLD) type 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. 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.With radial, axial and angular axis deviation compensation capabilities, GCLD (GⅡCLD) type drum gear coupling has compact structure, small turning radius, large load capacity, high transmission efficiency, low noise and long maintenance cycle, etc. Advantages, especially suitable for low-speed and heavy-duty working conditions, such as metallurgy, mining, lifting and transportation industries, and also suitable for shaft transmission of various machinery such as petroleum, chemical industry, general machinery, etc.

　　When the GCLD (GⅡCLD) type 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. The shaft device needs to work in a good and sealed state.Gear couplings have small radial dimensions and large load-bearing capacity. They are often used for 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-shaped gear couplings is greater than that of straight-tooth couplings, drum-shaped gear couplings are widely used both inside and outside. Straight-tooth couplings are obsolete products, and those who choose them should try not to use them.
