scope:

This standard provides a method to determine the power rating of gear sets for cylindrical grinding mills, kilns, coolers, and dryers. The formulas are applicable to steel and spheroidal graphitic iron gears with machined spur, single helical, double helical, or herringbone gear teeth commonly used for this purpose. Calculations determine the allowable rating for pitting resistance and bending strength of external spur and helical involute gear teeth.
