Gear Couplings transfer the torque between two independently supported shaft trains. This served to compensate relative angular, radial and axial displacement of the shafts occurring in operation.
Requirements of Gear Couplings:
Transmission of torque without slip and therefore without wear and tear to any coupling components.
No elastic elements meaning, no aging parts. Gear couplings are used for longitudinal and angular compensation as well as to compensate for the displacement of two parts to each other. The couplings shouldn’t generate external forces and should not cause vibrations.
Gear couplings consist of three fundamental parts. Basically these parts are two hubs, mounted on the shafts, to be coupled, and a floating element. The hubs can be manufactured with external or internal toothing. The sleeve is made to fit accordingly.
