Abstract

Planetary transmissions are important mechanical devices used in modern automobiles. They are composed of sun gears and planet gears that can be combined in different ratios to achieve different speeds. Central Washington University has a Ford Model-T planetary transmission with no effective way to demonstrate its function to students. This project explores the design and manufacture of a suitable fixture to effectively show the transmission as it operates to students. This was accomplished though shear and bending stress analysis of the frame members. Stress analysis in drive shafts and axles used in the fixture was also performed, along with a gear analysis of the transmission. This project also shows the manufacturing methods used during construction such as welding and machining. The analysis resulted in correct sizing and placement of frame members, sizing and location of shafts, and gear ratio values.
