New relationships for involute spur gear geometry are introduced and integrated with new methods of correlating lubricant traction and windage test data. Compact math models for lubricant density and viscoSity under contact prtssun are proposed. A modem approach to dimensional anaiysis is introduced to characterize lubricant traction data and gear windage data with dimensionless terms which apply to gear systems which may have aconfiguration and/or size different from those tested. Finally, system considerations for optimal gearbox efficiency arc proposed.
