Gear Coupling

The purpose of the gear coupling is to connect two independently supported shaft trains and transfer the torque, compensating 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 and therefore no aging parts.
  • Gear couplings are used for longitudinal and angular compensation and to compensate for the displacement of two parts to each other.
  • The couplings should not, as far as possible, generate external forces and preferably produce no vibrations.

Gear couplings fundamentally consist of three parts, namely two hubs (rigid elements), mounted on the shafts to be coupled, and a floating member. The hubs can be produced with external or internal toothing. The sleeve is manufactured to fit accordingly.
