In mathematics, an involute (also known as an evolvent) is a particular type of curve that is dependent on another shape or curve. An involute of a curve is the locus of a point on a piece of taut string as the string is either unwrapped from or wrapped around the curve. [1] The evolute of an involute is the original curve.
In effect, the involute shape of the gear teeth allows the contact point to move smoothly, transmitting the motion. Therefore, the involute curve is the ideal shape for gear teeth. Features : Conjugate action is relatively independent of small errors in center distance; Can be manufactured at low cost since the tooth profile is relatively simple

The definition of involute curve is the curve traced by a point on a straight line which rolls without slipping on the circle. The circle is called the base circle of the involutes. Fig. 3.3 The Involute Curve. In Fig.3.3, invα stands for Involute Angle (Involute α). The units for inv α is radians. θ is called involute rolling angle.
