Drum Gear Coupling

RFQ information to confirm before quotation

A drum gear coupling consists of two crowned external gear sleeves and a pair of straight internal gear rings. Torque is transmitted through internal and external gear meshing, while the crowned sleeve can swing inside the internal gear ring to compensate angular, axial and radial misalignment between shafts. The crowned tooth profile improves tooth contact, giving the coupling high torque capacity, large angular displacement, smooth transmission, high efficiency and long service life. It is widely used in metallurgical machinery, heavy machinery, mining equipment, cranes and conveying systems.
