Gear Teeth.
Abstract
ANSI/AGMA 2001 specihes a method for rating the pthing resistance and bending strength of spur and helical involute gear pairs. A detailed discussion of factors influencing gear survival and calculation methods are provided.
ANSI/AGMA 2001 provides a method by which different gear designs can be theoretically rated and compared. It is not intended to assure the performance of assembled gear dnve systems. These fundamental rating formulas are applicable for rating the pitting resistance and bending strength of internal and external spur and helical involute gear teeth operating on parallel axes. The formulas evaluate gear tooth capacity as influenced by the major factors which affect gear tooth pitting and gear tooth fracture at the fillet radius. The knowledge and judgment required to evaluate the various rating factors come from years of accumulated experience in designing, manufactunng, and operating gear units. Empirical factors given in this standard are general in nature. AGMA application standards may use other empirical factors that are more closely suited to the particular field of application. This standard is intended for use by the experienced gear designer, capable of selecting reasonable values for the factors. It is not intended for use by the engineering piElic at large.
