This part of the software rates gears exactly as intended by the American Gear Manufacturers Association Standards:
“ANSI/AGMA 2001-D04 and ANSI/AGMA 2101-D04, AMERICAN NATIONAL STANDARD, Fundamental Rating Factors and Calculation Methods for Involute Spur and Helical Gear Teeth.”
RATE2001 performs the following additional analyses:
Life Rating - given the transmitted power and speed, the pitting life and bending fatigue lives are calculated for a single load and speed, or for an entire spectrum of loads and speeds with the resultant lives determined from Miner's Rule.
Power Rating - given the pinion speed and required design life, the allowable transmitted power based on gear tooth pitting and bending fatigue is calculated for both the pinion and gear. The allowable power rating of the gearset is the minimum of the four power capacities.
