ISO/TR 14179-2 is the second part of a two-part document on gear thermal capacity. While provides calculation methods for thermal behavior of gear units (based on lubricant temperatures and heat balance), Part 2 gives supporting information, examples, and practical guidance on applying the thermal capacity calculations. iso tr 14179-2 pdf

You have a helical gearbox transmitting 150 kW at 1500 rpm. The ambient temperature is 30°C. You want the maximum oil temperature to be 80°C. Let’s walk through a simplified application of the

Scuffing is a form of gear failure caused by the welding together of gear tooth surfaces, followed by tearing. It happens when the lubricant film breaks down due to high local temperatures. ISO TR 14179-2 provides the mathematical formulas to predict the "Flash Temperature"—the momentary temperature spike that occurs when gear teeth mesh.
