The Gear Tooth Form 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. Gear Tooth Form Apparatus a bench top base plate contains all elements for this experiment. Three gears are located onto the base plate. 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. A large gear and small gear mesh together and can be rotated to produce analysis of ratios.
A set of vernier calipers is provided to allow the removable gear to be measured to help give a practival analysis of the Gear Tooth Form Apparatus.
Experimental Capabilities:
Explanation of Gear Ratios
Explanation of Gear Modules
Explanation of Gear Form
Explanation of Gear Trains and Rotational Direction
Experimental determination of shape and construction of an involute curve.
