Measure all external surfaces. The standard includes a correction for ribs and protrusions.
The standard provides detailed empirical formulas for calculating the (f_T). If f_T is less than 1.0, the gearbox will overheat under continuous operation. iso tr 14179-2 pdf
“The PDF is just theoretical math with no real-world use.” Truth: The formulas are validated against hundreds of production gearboxes from manufacturers like Flender, SEW, and Sumitomo. Measure all external surfaces
is a Technical Report (TR) titled "Gears — Thermal capacity — Part 2: Thermal load-carrying capacity". It provides a standardized framework for evaluating how much power a gear unit can handle before reaching critical operating temperatures. Purpose and Scope iso tr 14179-2 pdf
This is the power of having the PDF at your desk.
