This information sheet utilizes an analytical heat balance model to provide a means of calculating the thermal transmittable power for a single- or multi-stage gear drive lubricated with mineral oil. The calculation is based on standard conditions of 25C maximum ambient temperature and 95C maximum oil sump temperature in a large indoor space, but provides modifiers for other conditions. This document is not identical to ISO/TR 14179-1 as a) errors were identified and corrected, b) text was added to clarify the calculation methods, and c) an illustrative example was added to assist the reader.
