Projects for 2019-2020 school year:


Design Project 2019-1

Title: 3D printing of spiral bevel gears
Supervisor: Prof.  Paul Zsombor-Murray
The term(s) to begin: Fall 2019 or Winter 2020
Brief project description: Gear transmissions continue to be the most efficient means of transmitting mechanical
power through a step change in shaft speed. Efficiency is achieved by tooth profile designs that optimize rolling
between engaged tooth surfaces. Contact force is more widely distributed among teeth if they are spiraled about
the rotating axes. To this day bevel gearing, i.e., with intersecting rather than parallel axes, are not manufactured
according to design based on optimal form which engenders involute curves on a continuum of pitch-spheres in
the case of spiral bevel gearing (SBG). This project is to produce a 3D printed model of an optimally designed gear
pair; a proof of concept before attempting to evaluate potentially achievable efficiency improvement compared
to a similar commercially available gear set. A non-optimal pair of printed SBG and a design sketch summarizing
the principle of optimal SBG design are appended.
