I completed this gearbox design over the course of two classes focused on learning SolidWorks. I was given instruction on modeling the different parts and assemblies in SolidWorks, but these parts were initially filled with design flaws, courtesy of our mechanical design instructor. Through learning design principles such as fastener specification, tolerance specification, the use of standard fit tables, design for manufacturability and design for assembly, I was able to apply those principles to accurately specify retaining ring and bushing sizes, as well as properly design and tolerance the mating features on the designed parts such as the shaft fits and groove dimensions and tolerances.

​

I also independently brainstormed and developed design solutions for the gearbox to better design for manufacturability and assembly. I concluded my design by integrating the two side covers holding the worm gear shaft into the housing as well as going from two different sizes of cap screw to one size.

Completing this gearbox was a huge learning process for becoming comfortable using SolidWorks to do mechanical design and proficient in applying mechanical design principles, that university engineering graduates seldom have at graduation.
