NGCLZ drum 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.The contact state along the tooth width when there is angular displacement.
