Involute tooth equation

WebCalculating the forces on an involute spur gear is easy. Because of the involute tooth design, the worst loading cast is when the gears mesh where the pitch diameters intersect at the tangent point. Since the gears mesh at the pressure angle (14.5°, 20° or 25°). we will have two components to deal with. The tangential force and the radial force. WebIn involute gear design, contact between a pair of gear teeth occurs at a single instantaneous point (see figure at right) where two involutes of the same spiral …
