WGI type drum gear coupling

description:WGI-type drum-shaped gear coupling The so-called drum-shaped 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-shaped gear coupling can allow greater angular displacement ( Compared with the straight tooth coupling), the contact condition of the tooth can improve the torque transmission ability and prolong the service life.

Detailed introduction:

WGI type drum gear couplingThe so-called drum tooth is to make the external teeth into a spherical surface. The spherical surface is on the gear axis. The tooth side clearance is larger than that of the general gear. The drum tooth coupling can allow larger angular displacement (compared to the straight tooth coupling). The contact condition of the tooth can improve the torque transmission ability and prolong the service life.The contact state along the tooth width when there is angular displacement. When the gear coupling is working, the two shafts produce relative angular displacement. 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. , Gear couplings need to work in a good and sealed state.Gear couplings have small radial dimensions and large load-bearing capacity. They are often used in shaft transmissions under low-speed and heavy-duty conditions. The dynamically balanced gear couplings can be used for high-speed transmissions, such as gas turbine shaft transmissions.Because the angular compensation of drum gear couplings is greater than that of straight gear couplings, drum gear couplings are widely used. Straight gear couplings are obsolete products, and those who choose them should try not to use them.

WGI type drumGear couplingIt belongs to 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 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 couplings), the contact conditions of the teeth can be improved, the ability to transmit torque is improved, and the service life is prolonged.
