Can Opener Gearbox Design
MIE243 Dissection Project | Fall 2020
For my MIE243 - Mechanical Engineering Design course, we were to get into groups and
complete a 'dissection' every week, which consisted of "taking apart" (virtually) a
mechanism and re-designing and improve upon it.
For our third dissection, we took apart a can opener
and created a CAD of the internal gearbox, as well as design changes to increase the torque output of the gear
train by 25% to 50%.
I was responsible for the CAD design of the motor, the gear attached to the motor,
the middle 2 gears and the case/housing of the gearbox.
This project taught me a significant amount
about gear ratios, gear designs and gear parameters (pitch circle diameter, diametral pitch, etc.). I also
learned how to work collaboratively using SOLIDWORKS to design things.
