  WGC vertical installationDrum toothCouplingIt is composed of internal gear ring with the same number of teeth and flange half coupling with external teeth.When the gear coupling is working, the two shafts produce relative angular displacement. The tooth surfaces of the internal and external teeth periodically slide relative to each other in the axial direction, which will cause tooth surface wear and power consumption. Therefore, the gear coupling must have a good and Work in a sealed state.
WGC vertically installed drum 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. Highly and dynamically balanced gear couplings can be used for high-speed transmissions, such as combustion engines. The shafting transmission of the steam turbine.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 spherical surface is on the gear axis. The tooth side clearance is larger than that of ordinary gears. Drum-shaped gear couplings allow Larger angular displacement (compared to straight tooth coupling) 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.Since 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. Straight gear couplings are obsolete products. Those who choose should try not to use them. .
