Speed Gear Reducer

This Gear reducer was made @ University project. It is all started from 0, with all based calculus ( speed ratio, angles, pitches, degrees, forces, torques, payloads, material properties and more ). The main condition for that project was to draw it on the paper and just some drawings on CAD software, 2D drawings, but i went further and did this gear-box reducer assembly ! It looks nice ! :-)
