Gear types can be classified according to the relative position of their axes of revolution. For example, there are gears for parallel shafts, gears for intersecting shafts, and gears for skewed shafts. Spur and helical gears are two different types of mechanical gears falling under the category of “gears for parallel shafts”. Spur gears are used in many devices, like the electric screwdriver, wind-up alarm clock, and washing machine. Helical gears, on the other hand, operate much more smoothly and quietly than spur gears. Helical gears are used in almost all car transmissions. Look as hard as you like, but you won’t find spur gears in your car!
