Home - Gear Coupling

A gear coupling is a mechanical device for transmitting torque between two shafts that are not coaxial. A gear coupling that utilizes a sleeve is considered a flexible coupling, as they allow for some degree of misalignment between shafts. A complete gear coupling consists of at least two hubs, and if flexible at least one sleeve.
