A Parametric Study of Spur Gear Bending Strength

The variables affecting bending strength of spur gear teeth have been reviewed with the purpose of showing the magnitude and trend in the change of strength as a result of a change in a variable. Also presented is a unique interactive computer program giving numerical results as well as displaying the tooth profile as it is being generated by the hob. This demonstrates the dramatic change in the tooth profile which can result while either developing the maximum strength of the tooth or optimizing the strength of a gearset.
