Manually calculating thermal capacity with the PDF is tedious. Most modern gear design software includes this standard: iso tr 14179-2 pdf

The thermal load-carrying capacity is expressed as the maximum power a gear unit can transmit while maintaining its oil sump temperature within safe operating limits (typically at or below a specified allowable temperature). Exceeding this limit can lead to: Exceeding this limit can lead to: ): Friction
): Friction inside the rolling element or journal bearings, influenced by shaft speed and external loads. Seal Losses ( PVdcap P sub cap V d end-sub
Many beginners confuse this standard with others. Here is a quick comparison:
