Rates gear drives based on a fixed thermal equilibrium at an artificial limit of 95 °C oil sump temperature.

ISO/TR 14179-2 is the second part of a two-part document on gear thermal capacity. While provides calculation methods for thermal behavior of gear units (based on lubricant temperatures and heat balance), Part 2 gives supporting information, examples, and practical guidance on applying the thermal capacity calculations.

The entire methodology of the standard relies on the physical law of conservation of energy. For a gearbox operating in a steady-state (quasi-stationary) condition, the generated power loss ( PVcap P sub cap V ) must exactly equal the total dissipated heat ( PQcap P sub cap Q PV=PQcap P sub cap V equals cap P sub cap Q iso tr 14179-2 pdf

If you are working on a specific calculation using this standard, please let me know:

Heat generated inside the gearbox leaves the system through several pathways: Rates gear drives based on a fixed thermal

It is developed by (Technical Committee on Gears, Subcommittee on Gear Capacity Calculation) and carries the ICS classification 21.200 (Gears and gearing).

The core objective of ISO/TR 14179‑2 is clearly stated in its abstract: The entire methodology of the standard relies on
