What is the distance between a point on the face of one gear tooth to the same point on the next tooth?

• A. Diametral pitch
• B. Circular pitch
• C. Working depth
• D. None are correct.

Answer: (B)

The distance between a point on the face of one gear tooth to the same point on the next tooth is known as the circular pitch. This measurement is crucial in understanding the spacing and arrangement of the teeth on a gear. Circular pitch is defined as the distance measured along the pitch circle from one tooth to the corresponding point on the adjacent tooth. It helps in determining how gears will mesh and function together in a mechanical system, contributing significantly to the system's efficiency and performance. In contrast, the diametral pitch refers to the number of teeth per inch of the gear diameter, which is related to the size of the teeth rather than the spacing. Working depth is a measure associated with the depth of the tooth engagement but does not pertain specifically to the distance between teeth. Thus, the only correct term for the distance in question is circular pitch.
