Variable to Constant Gearbox Prototype

This is part of a study being done by Dr. Salim Azzouz of the McCoy School of Engineering at Midwestern State University. Senior Engineering students were challenged to find and/or design a gearbox that would transform a variable rotational input to an output at a constant angular velocity. This is the resulting study prototype, which uses a printed planetary gear train to accomplish the desired results.

If the single shaft is used as the input, it will drive the output (sun gear) at the same
