python-gearbox#

Gear strength with ISO 6336 and AGMA 2001, and finite-element analysis of gear teeth.

Will this pair of gears survive? python-gearbox answers with the standards designers use, shows every factor behind the answer, and — when a standard is not enough — lets you mesh the real tooth and solve it with finite elements.
