Please educate me on this subject:
Gear calculations typically use only allowable stress and hardness to calculate power ratings and gear life. These values are listed by the AGMA number like A1 or A5.
Designing a set of gears I only have mechanical information for a specific type of Alloy- tensile and yield strengths.
SO:
What is the allowable stress? -I know this is listed by AGMA and modified by operating factors, but how is it calculated to start with? I only have tensile and yield strength to start with for the particular alloy I have selected.
Is the allowable stress the same as the endurance limit (fatigue strength) of the particular alloy?
Is there a cross-reference for the AGMA numbering system to AISI?
Anyone know?
