Iso Tr 14179-2 Pdf
ISO/TR 14179-2:2001 is a technical report that provides standardized methods for determining the thermal load-carrying capacity of gear units. It focuses on assessing how much power a gearbox can transmit without exceeding safe operating temperatures, which is critical for preventing lubricant failure or mechanical damage. Scope and Purpose
The PDF shows her that natural convection isn't enough. Using the formulas in Section 6.5 , she calculates exactly how much external cooling iso tr 14179-2 pdf
Radiation from the housing based on the Stefan-Boltzmann law. ISO/TR 14179-2:2001 is a technical report that provides
- Annexes with real test rig data from gearboxes ranging from 1 kW to 1 MW.
- Permissible oil sump temperatures for mineral, PAO, and PAG lubricants.
- A worked example stepping through a 50 kW industrial gear unit – showing how ignoring Part 2 leads to a 25°C underestimation of operating temperature.
Without this document, you are essentially guessing the thermal safety margin of your gear drive. Exceeding the thermal capacity leads to: Annexes with real test rig data from gearboxes
Determine if a gearbox requires auxiliary cooling (like fans or heat exchangers).
Who Should Use This?
- Gearbox designers needing to predict thermal limits without over-engineering cooling.
- Application engineers selecting standard gear units for high-ambient or enclosed environments.
- Failure analysts investigating thermal damage (scuffing, oxidation, seizure).
- Students or researchers studying gear tribology or power transmission.
