AGMA, ISO, and BS Gear Standards Part II - Pitting Resistance Ratings
The article "AGMA, ISO, and BS Gear Standards Part II - Pitting Resistance Ratings" appeared in the January/February 1991 issue of Gear Technology.
In Part I differences in pitting ratings between AGMA 218, the draft ISO standard 6336, and BS 436:1986 were examined. In this part bending strength ratings are compared. All the standards base the bending strength on the Lewis equation; the ratings differ in the use and number of modification factors. A comprehensive design survey is carried out to examine practical differences between the rating methods presented in the standards, and the results are shown in graphical form.
