Addendum circle is the circle drawn through the top of the teeth and is concentric with the pitch circle. Dedendum circle is the circle drawn through the bottom of the teeth. It is also called root circle. Pitch circle is an imaginary circle which by pure rolling action, would give the same motion as the actual gear.

An imaginary circle which by pure rolling action, gives the same motio...
Explanation:
The imaginary circle that gives the same motion as the actual gear by pure rolling action is called the pitch circle. The pitch circle is an important concept in gear design and is used to determine the size and shape of gears.
Definition of Pitch Circle:
The pitch circle is a theoretical circle on which the teeth of a gear are placed. It is a circle that represents the average diameter of the gear and is used to determine the gear ratio and the spacing of the teeth.
Key Points:
- The pitch circle is the circle that two gears roll on each other without slipping.
- The pitch circle is defined by the number of teeth on the gear and the diametral pitch (teeth per inch of pitch diameter).
- The pitch circle diameter is calculated by dividing the number of teeth on the gear by the diametral pitch.
- The pitch circle is used to determine the gear ratio, which is the ratio of the number of teeth on the driving gear to the number of teeth on the driven gear.
- The pitch circle is also used to determine the center distance between two gears, which is the distance between the centers of two meshing gears.
- The pitch circle is important in gear design because it allows for the accurate sizing and spacing of gear teeth.
- The pitch circle is also used to determine the addendum circle, dedendum circle, and base circle of a gear.
Conclusion:
In conclusion, the pitch circle is an imaginary circle that gives the same motion as the actual gear by pure rolling action. It is an important concept in gear design and is used to determine the size and shape of gears. The pitch circle is defined by the number of teeth on the gear and the diametral pitch, and it is used to calculate the gear ratio and spacing of the teeth.
