What is a gear? By: Fatima
What is a gear? A gear is a toothed wheel, cylinder, or cone that transmits motion from one part of a machine to another.
What is a helical gear? • A helical gear is similar to a spur gear, but its teeth are twisted instead of straight. • Helical gears can be used to transmit motion between shafts that do not intersect and are at any angle with respect to each other.
What is a worm gear? • A worm gear, meshed with a threaded cylinder, or worm, that resembles a screw, is used to transmit motion between perpendicular, nonintersecting shafts.
