This thesis meets a need of selecting and using appropriate involute spur gear design approaches for all designers including the expert designers and novice learners who are practicing a spur gear design. Five design approaches with different level of difficulty, including the most commonly used machine elements textbooks, national and international standards were selected for comparison of design results. The results of each approach were analyzed by using a finite element method, ANSYS. And the loss or gain obtained from each of the approach was determined and results were given comparatively considering the gear failures criteria, speed ratios and power transmission ranges. Useful 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 multiply the results of simple gear design approaches to ANSI/AGMA standards or in any of the five selected one. It also offers the best approach for students and designers who aim to optimize the gear design.
