Abstract:

This thesis meets a need of selecting and using appropriate involute bevel gear design approaches for all designers from the expert to novice learners who are practicing a straight bevel gear design. Four straight bevel gear design approaches with different level of difficulty, including the ones available in the most commonly used machine elements textbooks, national and international standards were selected for comparison of design results. The results of each approach were analysed by using a finite element method, ANSYS. And the variations on the design results of each of the approach were determined, and the results were given comparatively considering the gear failures criteria, speed ratios and power transmission ranges. The outputs, practical curves and charts were introduced to select the appropriate design approach. In addition to this, the study provides conversion factors which may be used to translate the results of simple gear design approaches into ANSI/AGMA international standards or in any of the four selected one by multiplying with the appropriate conversion factors. It also offers the best approach for students and designers who aim to optimize the bevel gear design.
