AB  - Design and Fabrication of a Planetary Gearset as Part of a Hybrid PowertrainConcept retention between courses is a recurring problem for engineering educators – a problemexacerbated by the disjointed nature of the engineering curriculum. One possible solution to theproblem, a multi-year design/build/test project, is currently being studied by the authors. Theproject discussed in this paper – the design and fabrication of a planetary gearset – is the “heart”of a bench-scale hybrid powertrain completed by our students over the course of five semesters.This is the latest installment in a series of papers discussing the project; see [1-4] for a fulldescription.Most gearsets have a single input and a single output; e.g. the speed reducing gears in a foodprocessor or window opener. Planetary gearsets, in contrast, have two inputs and one output.This makes them very useful where motion from two sources must be integrated, as in a hybridpowertrain where power from an electric motor and an internal combustion engine is combinedto produce the desired speed at the wheels. For this project, mechanical engineering juniors in aMachine Design course were given the task of designing and fabricating a planetary gearset tocombine input from an electric motor (the same for every team, with a speed range of 0-1000rpm) with input from the student-constructed air motor (speed range dependent on theteam’s design) to produce an output speed that can be regulated to 500rpm (by varying the speedof the electric motor).To begin, the students were presented with SolidWorks models of twelve possible planetarygearset configurations. To help the students to visualize the counterintuitive behavior ofplanetary gearsets, three faculty prototypes were constructed, and will be described in the fullpaper. Each student team was given a $20 budget to purchase gears, bearings and otheressentials. An extensive website describing planetary gearsets and their design has beendeveloped by the authors, and is freely available to instructors at other institutions. This websiteand the results of conducting this project on two cohorts will be discussed in the final paper.[1] M. Acosta, K. Bhatia, E. Constans, J. Kadlowec, T. Merrill, H. Zhang, B.
