Jiangsu NGCL type drum gear coupling with brake wheel

NGCL type drum gear coupling with brake wheel has two types: A type and B type. Type A is suitable for NGCL1～NGCL13, and B is suitable for NGCL14.

When the gear coupling is working, the two shafts produce relative angular displacement, and 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. The gear coupling must be in a good and sealed manner. Work under 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.

Drum gear is made of external teeth 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 larger angular displacement relative to the straight gear coupling, and the teeth can contact. Conditions, improve the transmission torque capacity, extend the service life, have the radial, axial and angular axis deviation compensation capabilities, have the advantages of compact structure, small gyration radius, large carrying capacity, low transmission, low noise and long maintenance cycle. .

NGCL type drum gear coupling with brake wheel is composed of internal gear ring with the same number of teeth and flange half coupling with external gear.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 a general gear. Larger angular displacement (compared to spur gear couplings), the contact conditions of the teeth can be improved, the torque transmission capacity is improved, and the service life is prolonged.
