How do you calculate the tooth surface hardness profile of 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.
