For each active gear mesh, the torque dependent efficiency shall be set to constant values of ηm:

external – external gear meshes

  • ηm = 0,986

    • external – internal gear meshes

  • ηm = 0,993

    • angle drive gear meshes

  • ηm = 0,97

    • (Angle drive losses may alternatively be determined by separate testing as described in paragraph 6. of this Annex)
