Spur Gear Design 3 - Construct, Edit and Animate

How to design and make a working spur gear, calculate the involute of the circle and animate. This video shows how to manipulate the template gear using equations.

This video follows on from parts 1 & 2 which details how gears of different diameters interact or mesh, identifies which characteristic control the gear ratio and why the module is important. The relationship between addendum and dedendum in terms of clearance is also discussed. Video 2 details how the involute of a circle is calculated. characteristics of gear design including the top land, face, flank, bottom land, gear tooth profile, pitch circle, circular pitch, dedendum, addendum, whole depth, addendum circle, clearance circle, root circle, base circle, pressure angle, line of action and angle of interaction are all discussed in this series..
