Abstract / scope
This document specifies a means for determining the thermal load-carrying capacity of a gear unit that includes measurement on original gear units under practical conditions. This takes the form of either measurement of the power loss, heat dissipation or both, or, in the case of splash-lubricated gear units, the determination of the quasi-stationary temperature in the oil sump.
An alternative method is all the methods of calculation for all individual components of power loss and heat dissipation described in this document.
