Simulation of Generation Process for Asymmetric Involute Gear Tooth Shape with and without Profile Correction

Abstract

In order to achieve any design study on a gear tooth or to carry out any type of analysis on a complete gear drive, the first step is the representation of the actual form of this tooth under consideration. In this work, a mathematical simulation of generation process for the symmetric involute gear teeth shapes based on the principle of the gear shaping process with a rack-shaped cutter has been developed to take into account the effect of asymmetric tooth profiles and the use of profile correction on each side of tooth with different design parameters for each side of tooth. As a result of this work, a computer program based on this mathematical simulation has been built to represent graphically step-by-step the actual form of symmetric and asymmetric gear teeth shapes with and without profile correction for different gear design parameters.
