teeth on helical gears are cut at an angle to the face of the
gear this increases the strength of the teeth because of the elongated
helical wrap around.
two teeth on a helical gear system engage, the contact starts
at one end of the tooth and gradually spreads as the gears rotate,
until the two teeth are in full engagement.
This gradual engagement makes helical gears operate more smoothly
and quietly than spur gears. For this reason, helical gears are
commonly used in automotive transmissions.
