A pulley is a wheel on an axle or shaft enabling a taut cable or belt passing over the wheel to move and change direction, or transfer power between itself and a shaft. A sheave or pulley wheel is a pulley using an axle supported by a frame or shell (block) to guide a cable or exert force.
What is a Pulley. A pulley is a simple machine consisting of a wheel rotating about its axle. It is constructed by looping a rope or a cable around the groove of the wheel. Therefore, the three main parts of a pulley are the wheel, axle, and rope.
A pulley is simply a collection of one or more wheels over which you loop a rope (or chain) to make it easier to lift things. Here's an everyday example: Photo: A pulley mounted on a huge lifting frame to make it safer to use.
A pulley is a wheel that carries a flexible rope, cord, cable, chain, or belt on its rim. Pulleys are used singly or in combination to transmit energy and motion. Pulleys with grooved rims are called sheaves.
