## Detailed Solution

Explanation:

Following are some basic gear terminologies used in gear design.

Gear TerminologiesMeaningModule (m)

It is the ratio of the pitch diameter to the number of teeth.

m=dT

where d = pitch diameter and T = number of teeth.

Circular pitch (p)

It is the distance measured along the circumference of the pitch circle from a point on one tooth to the corresponding point on the adjacent tooth.

p=πdT⇒πm

Diametral pitch (P)

It is the number of teeth per unit length of the pitch circle diameter.

P=Td

Gear ratio (G)

It is the ratio of the number of teeth on the gear to that on the pinion.

where T, t = number of teeth and gear and pinion respectively.

Pitch point

The point of contact of two pitch circles is known as pitch point.

Space width (b)

It is the width of the tooth space along the pitch circle.
