How do you calculate the tooth surface stress profile in straight bevel gears?
Introduction
A straight bevel gear is a type of bevel gear that has straight teeth and a conical shape. It is used to transmit power between intersecting shafts at a right angle. The teeth of a straight bevel gear are cut straight and parallel to the generator cone, resulting in a gear with a straight tooth profile.
