is a technical report that provides a comprehensive framework for determining the thermal load-carrying capacity of industrial gear units . While structural strength often dictates gear design, the thermal limit—the power a gearbox can transmit without overheating—is equally critical to prevent lubricant degradation, scuffing, or component failure. Core Purpose and Scope

Heat transferred through the foundation and connected shafts or couplings.

This technical report describes how to assess the thermal balance of a gear unit by calculating the equilibrium between (heat) and heat dissipation to the environment. It is applicable to various gear types, including cylindrical, bevel, hypoid, and worm gears. iso tr 14179-2 pdf

Includes both load-dependent losses (related to tooth friction) and no-load (churning) losses.

Heat transfer through the housing walls based on the Stefan-Boltzmann law and surface finish coefficients. is a technical report that provides a comprehensive

Heat generated by shaft seals and other rotating elements. 2. Heat Dissipation Paths It provides equations for how heat leaves the system:

The report breaks down internal heat generation into several factors: This technical report describes how to assess the

The methods described in ISO/TR 14179-2 were heavily influenced by research from the and the FVA (Forschungsvereinigung Antriebstechnik e.V.) in Germany. A widely used industrial software, WTplus , incorporates these exact calculation procedures for gearbox design. Where to Obtain the PDF
