DESCRIPTION

A bench top base plate contains all elements for this experiment.

Three gears are located onto the base plate. A large gear and small gear mesh together and can be rotated to produce analysis of ratios. A third gear is removable to allow students to review its tooth form, pitch circle diameter (PCD) and other key geometry of a tooth form.

The apparatus also explains the form of an involute curve and how this is used to create a gear tooth profile. To help describe what an involute curve is, paper can be placed into the apparatus and an involute curve drawn. A set of vernier callipers is provided to allow the removable gear to be measured to help give a practical analysis of the gear form. Labels are used on the unit to help clearly explain gear theory.
