Core Content of ISO TR 14179-2
If you obtain the ISO TR 14179-2 pdf, you will find detailed methodologies for calculating the thermal limit. Here is a breakdown of the major sections: Gear Mesh Losses ($P_VZ$): It provides formulae for
5. Permissible Thermal Power
The final output is a thermal rating curve (Power vs. Speed). If your application exceeds this curve, you must add external cooling.
The technical report breaks down the thermal load-carrying capacity into several major components:
You're looking for information related to ISO/TR 14179-2, which is a Technical Report (TR) published by the International Organization for Standardization (ISO).
- Gear Mesh Losses ($P_VZ$): It provides formulae for calculating friction coefficients based on sliding and rolling action. It accounts for the influence of gear geometry (involute contact ratio) and lubrication regimes.
- Bearing Losses ($P_VL$): It includes methods for estimating frictional torque in rolling element bearings, heavily referencing ISO 281 and bearing manufacturer data.
- Seal Losses ($P_VD$): Though typically minor, the document accounts for friction at shaft seals.
- Auxiliary Losses: It discusses losses from oil pumps or other internal components.
