Mechanisms: Pulleys | |
   | Pulleys are used to transfer rotating motion, via a belt, from one shaft to another. The vacuum cleaner uses a pulley to transmit power from the electric motor to the rotating brushes. If both pulleys are the same diameter, then they will both rotate at the same speed. If one pulley is larger than another then mechanical advantage and velocity ratio are introduced. A large drive pulley will cause a smaller driven pulley to rotate faster. |
