Abstract

The focus of this project was to design a drive system that could replace the conventional chain drive system, improving on both the efficiency and reliability, in addition to being low cost and lightweight. This report will provide background into why this group chose this as the subject of their project, as well as challenges faced throughout the design process. The design developed was a drive shaft driven by a system of pinions and gears, with a freewheel mechanism that allowed the system to coast when not pedaling. Due to cost and time constraints, only a prototype was created, with additional research into materials selection and testing of our design. Despite this, there is still an enormous amount of potential to explore from this project as to alternatives to the traditional chain and sprocket drive shaft. We would like to thank our advisor David Peters for guiding us through this project, as well as Dr. Greg Morscher for assisting us with the materials selection software.
