Heat transfer through the housing walls based on the Stefan-Boltzmann law and surface finish coefficients.

The methods described in ISO/TR 14179-2 were heavily influenced by research from the and the FVA (Forschungsvereinigung Antriebstechnik e.V.) in Germany. A widely used industrial software, WTplus , incorporates these exact calculation procedures for gearbox design. Where to Obtain the PDF

Unlike ISO/TR 14179-1 , which focuses on a simplified analytical model for rating gear drives at a fixed 95 °C sump temperature, offers a more detailed approach that includes measurements on original gear units under practical conditions. Key Methodology: The Thermal Balance
