Correct Answer - Option 1 : 2 mm
Concept:
Circular pitch:
It is the distance along the pitch circle or pitch line between corresponding profiles of adjacent teeth.
\(P_c=\frac{\pi D}{T}\)
Module:
It is the ratio of diameter (in mm) and the number of teeth of gears.
\(m=\frac{D}{T}\)
∴ Pc = π × m
Calculation:
Given:
No of teeth, T = 22 and Pitch circle diameter, D = 14 mm
Circular pitch (Pc):
pc = π × m
\(p_c= \frac{22}{7}\times\frac{14}{22}\)
pc = 2 mm.
