Product Overview and Application Boundary
A gear coupling is usually composed of two externally toothed hubs, an internal gear sleeve, end covers, seals and fasteners. Torque is transmitted through internal and external gear meshing, giving the coupling high torque capacity in a compact envelope. It is suitable for hoists, conveyors, winches, reducer output shafts and heavy-duty drives with limited installation space. Selection should check nominal torque, allowable speed, bore d1/d2, keyway standard, shaft-end distance, lubrication, sealing and alignment condition. For replacement projects, drawings, old part photos or measured dimensions help verify tooth strength, bore fit, material, heat treatment and interchangeability.
