The software suite has integrated ISO/TR 14179 as a standard module:

ISO/TR 14179-2 is informative, not normative. It does not replace ISO 14179-1 but helps you apply it correctly.

When a gearbox operates, a small percentage of the transmitted mechanical energy is inevitably lost and converted into heat. If the heat generated exceeds the amount dissipated into the surrounding environment, the oil sump temperature will spiral upward.

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

Given a targeted transmitted torque and speed, engineers can calculate the exact steady-state oil sump temperature. This determines whether a standard oil formulation will survive or if a premium synthetic variant is required. 2. Maximum Continuous Transmittable Power iso tr 14179-2 pdf

The final output is a (Power vs. Speed). If your application exceeds this curve, you must add external cooling.

Understanding ISO/TR 14179-2: Thermal Capacity of Gear Units

Because Part 2 uses a detailed analytical approach, it allows designers to modify specific variables—such as housing shape, oil levels, and ambient wind speed—to optimize a gearbox for thermal efficiency. Why Thermal Capacity Matters in Gear Design

Ensuring large, continuous-duty drive systems do not overheat in dusty, stagnant underground environments. The software suite has integrated ISO/TR 14179 as

Unexpected structural failures halt production lines. Core Contents of the ISO/TR 14179-2 Document

ISO/TR 14179‑2:2001 is an essential tool for any engineer working with gear drives where thermal limits are a concern. It offers a for determining the thermal load‑carrying capacity of gear units, combining direct measurement (where possible) with alternative calculation methods for situations where testing is impractical.

Directly tracking the differential between input torque and output torque to isolate thermal conversion. If the heat generated exceeds the amount dissipated

Uncontrolled thermal escalation causes severe operational issues:

These are caused by the "churning" of oil as gears rotate and "windage" (air resistance). These depend heavily on speed and oil viscosity. 2. Dissipation Factors

To offset internal power losses, heat is pushed out through multiple channels:
