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

Assessment of requirements for oil coolers or injection lubrication systems. Practical Implementation

The report breaks down internal heat generation into several factors:

Calculations based on empirical data from bearing manufacturers' catalogs.

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

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
