Engineering Technologies, Safety, and Construction Faculty Scholarship
In studying mechanical gear train analysis, some students struggle with relatively simple gear design concepts, and virtually all have difficulty with the complexities of planetary gear sets. This paper describes two labs developed for an undergraduate senior level machine design course. One lab uses a three-speed manual synchromesh transmission with parts of the case cut away to demonstrate the operation of the gears, shifting mechanism, bearings, and other aspects of the design. Students then count teeth and analyze the gear ratios using standard gear train analysis methods. The other lab uses a 1924 Ford Model T planetary transmission to observe …
