Iso Tr 14179-2 Pdf File

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

Instead of hunting for a free, illegal copy riddled with errors, invest in the official PDF from ISO or your national standards body. The cost is negligible compared to a single gearbox failure caused by thermal scoring.

ISO TR 14179-2

is a Technical Report titled: "Gears – Thermal capacity – Part 2: Thermal load-carrying capacity." iso tr 14179-2 pdf

Oil Sump Temperature

: Specifically for splash-lubricated gear units, it provides methods to determine the quasi-stationary temperature in the oil sump. Key Components of Thermal Balance

Conclusion:

Heat generated (4.0 kW) >> Heat dissipated (0.6 kW) The gearbox will overheat instantly. You need a cooling fan or external oil cooler. ISO/TR 14179-2 - EVS standard evs

Analytical Calculation

: Offering an alternative method to calculate individual components of power loss and heat dissipation for all gearbox components.

Common Mistakes When Applying ISO TR 14179-2

Thermal Balance

: Includes equations for heat dissipation via natural and forced convection, radiation (based on the Stefan-Boltzmann law), and heat transfer through rotating parts or the foundation. Key Components of Thermal Balance Conclusion: Heat generated

ISO/TR 14179-2 is an indispensable tool for gear engineers aiming to optimize efficiency and reliability. By providing a standardized way to calculate thermal load-carrying capacity, it ensures that industrial machinery can run longer and hotter without catastrophic failure.
