If the tooth profiles are not designed as per the law of gearing then the motion transfer will not be proper because of improper meshing which results in vibration and tooth damage. Every Conjugate profile must satisfy the Law of gearing. They are as follows:
Cycloid:
- A cycloid is a curve traced by a point on the circumference of a circle which rolls without slipping on a fixed straight line.
Involute:
- An involute toothed profile of a circle is a plane curve generated by a point on a tangent, which rolls on the circle without slipping or by a point on a taut string which is unwrapped from a reel.
- Cycloid gear profile is a combination of epicycloid and hypocycloid curves.
- The face of a cycloidal gear consists of a portion of an Epicycloid, whereas the flank consists of a portion of a Hypocycloid.
