NGCLZ type intermediate shaft drum gear coupling with brake wheel

NGCLZ type connecting intermediate shaft with brake wheelDrum gear coupling, Gear coupling 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.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, 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 must have a good and Work in a 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. Straight gear couplings are obsolete products, and those who choose them should try not to use them.
