Description

A compact spur gear stage for a (fictional) conveyor retrofit. The brief was to fit an existing motor flange while dropping the output speed without a larger housing.

I modelled the gear pair in SolidWorks from the module and tooth counts, checked the mesh and backlash in a motion study, and produced fully toleranced manufacturing drawings for the gears, shafts and base plate.
