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:
“A good aphorism is too hard for the teeth of time and is not eaten up by all the centuries, even though it serves as food for every age: hence it is the greatest paradox in literature, the imperishable in the midst of change, the nourishment which—like salt—is always prized, but which never loses its savor as salt does.”
—Friedrich Nietzsche (1844–1900)
“I light matches and put them in my mouth,
and my teeth melt but the greenery hisses on.
I drink blood from my wrists
and the green slips out like a bracelet.
Couldn’t one of my keepers get a lawn mower
and chop it down if I turned inside out for an hour?”
—Anne Sexton (1928–1974)
