ISO/TR 14179-2:2001 provides standardized methods for calculating the thermal load-carrying capacity of gear units, balancing internal power losses against heat dissipation to determine maximum power transmission. The technical report covers both analytical calculations and practical measurement methods for gear, bearing, and seal losses to estimate oil sump temperatures. Official copies of the standard are available through organizations like ISO and DIN Media . ISO/TR 14179-2 - EVS standard evs.ee
The report defines the thermal equilibrium of a gearbox as the point where the (heat generated) equals the heat dissipation (heat removed). Power Loss Sources : iso tr 14179-2 pdf
