WebGear is one of the most critical component in a mechanical power transmission system, and most industrial rotating machinery. Spur gear is cylindrical in form and has teeth, which are of involute form in most cases [1]. A pair of spur gear teeth in action is generally subjected to two types of stresses: bending stresses and contact stress. WebInvolute Gear Calculator.
