Teeth
There are two issues regarding tooth shape. One is the cross-sectional profile of the individual tooth. The other is the line or curve on which the tooth is set on the face of the gear: in other words the line or curve along which the cross-sectional profile is projected to form the actual three-dimensional shape of the tooth. The primary effect of both the cross-sectional profile and the tooth line or curve is on the smoothness of operation of the gears. Some result in a smoother gear action than others.

Famous quotes containing the word teeth:
“An Indian’s teeth are strong, and I noticed that he used his often where we should have used a hand. They amounted to a third hand.”

Couldn’t one of my keepers get a lawn mower
and chop it down if I turned inside out for an hour?”

With eyes as wide as a football-pool,
Ears like bombs and teeth like splinters:
A blitz of a boy is Timothy Winters.”
