WGI type drum gear coupling

WGI typeDrum gear couplingIt is composed of internal gear ring with the same number of teeth and 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 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 spur gear coupling), the contact condition of the teeth can be improved, the ability of transmitting torque is improved, and the service life is prolonged.

WGI type drum gear coupling The so-called drum gear 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. The drum gear coupling can allow greater angular displacement. (Compared with the straight tooth coupling), it can improve the contact condition of the teeth, increase the torque transmission ability, and prolong the service life.In the contact state along the tooth width when there is angular displacement, 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 of WGI drum-shaped gear couplings are divided into two types: straight teeth and drum-shaped teeth. When the gear coupling is working, the two shafts produce relative angular displacement, and the tooth surfaces of the internal and external teeth act as the axis periodically. Sliding relative to each other will inevitably cause tooth surface wear and power consumption. Therefore, the gear coupling must work in a good and sealed state.

When the WGI drum gear coupling is working, the two shafts produce relative angular displacement, and the tooth surfaces of the internal and external 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 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.Since the angular compensation of drum gear couplings is greater than that of spur gear couplings, drum gear couplings are widely used. Straight gear couplings are obsolete products and should not be used as much as possible.
