The primary feature of ISO/TR 14179-2 (officially titled "Gears — Thermal capacity — Part 2: Thermal load-carrying capacity") is that it provides a practical framework for determining the thermal power limit of a gear unit through both empirical measurement and analytical calculation. ISO - International Organization for Standardization Core Technical Features Thermal Balance Assessment

: While Part 1 focuses on rating gear drives at a fixed 95 °C equilibrium, Part 2 offers a more flexible analytical heat balance model and experimental alternatives. Accessing the PDF iso tr 14179-2 pdf

: For splash-lubricated gears, it provides a way to determine the stable temperature of the oil in the sump. The primary feature of ISO/TR 14179-2 (officially titled

The document guides the engineer through solving the heat balance equation: $$P_V = Q_air + Q_oil + Q_rad$$ It helps determine the "Thermal Rating" of the gearbox—the horsepower limit at which the gearbox stabilizes at a safe operating temperature. The document guides the engineer through solving the

is a Technical Report titled: "Gears – Thermal capacity – Part 2: Thermal load-carrying capacity."

Most gearbox designers obsess over tooth bending stress (ISO 6336) or pitting resistance. But the silent killer of gearboxes isn't stress—it's . Every year, millions of dollars are lost to lubricant coking, tooth scuffing, and oil seal failure caused by underestimated thermal loads.
