Reduction Gearbox

At the end of my second year MECH 2409 Machine Elements Design course, our professor gave us one last assignment.  For it, he asked us to work with a couple other peers to create a gearbox design that met given requirements, using what we had learned in class over the term.

The requirements for the design were as follow:

  1. Reduction Ratio of 0.5
  2. Angular Input Speed of 360 rpm.
  3. Shaft distance of 18 to 22 cm.
  4. Output Torque of 60 Nm

For this project,  we were required to create conceptual designs, free body diagrams, SOLIDWORKS modelling and simulations, and some calculations.

Below is one of my group’s conceptual designs,

and below this is our final design.

For this project my group used helical gear, which added a bit more difficulty to our work as it added an extra factor to our AGMA calculations, which spur gears did not need.  After completing the AGMA Calculations, we found our factor of safety values to be as follow:

Our group then conducted SOLIDWORKS simulations including stress, deformation, and strain, and once all of this was completed we also included a maintenance plan for any consumer wishing to purchase our design.  To find these, click the link at the bottom of the page to view our presentation.
