: Provides means for determining thermal capacity via measurement of power loss, heat dissipation, or quasi-stationary oil sump temperatures in splash-lubricated units.
The document establishes standard protocols for evaluating the thermal equilibrium of gear drives. It balances the total power losses generated by internal friction against the environment's ability to dissipate that heat. The framework rests on two distinct tracks: and an analytical calculation model . iso tr 14179-2 pdf
| | Relationship | | :--- | :--- | | ISO/TR 14179-1:2001 | Part 1 focuses on rating gear drives with thermal equilibrium at a 95°C sump temperature.
