V-Tooth, Hirth, Voit, and Curvic Couplings

An extremely high precision coupling primarily used for power exchange between and impeller and a driving shaft.  Can also be used in shaft-to-shaft power transfer designs.

  • High precision couplings for high speed power transfer.

  • Made under rush time constraints

  • Cryogenic gas compression applications

  • Gas expanding impeller/turbine combinations

  • High torque transfer ability

  • Indexing of impeller to turbine allows for greater control during balancing
