In helical gears, the distance between similar faces of adjacent teeth along a helix on the pitch cylinders normal to the teeth, is called

A normal pitch
B axial pitch
C diametral pitch
D module

Correct Answer: normal pitch

Normal pitch is the distance between similar faces of adjacent teeth along a helix on the pitch cylinders normal to the teeth. Axial pitch is the distance, parallel to the axis, between similar faces of adjacent teeth.
