A pulley is a wheel on an axle or shaft that is designed to support movements and change of direction of a taut cable or belt, or transfer of electricity between your shaft and wire or belt. In the case of a pulley supported by a frame or shell that does not transfer power to a shaft, but is employed to guide the cable or exert a pressure, the assisting shell is called a prevent, and the pulley may be called a sheave.
A pulley may have a grooveor grooves between flanges around its circumference to locate the wire or belt. The drive element of a pulley program could be a rope, cable, belt , or chain .
The earliest evidence of pulleys date back to Mesopotamia in the early 2nd millennium BCE,[1] and Ancient Egypt in the Twelfth Dynasty (1991-1802 BCE).[2] In Roman Egypt ,Hero of Alexandria (c. 10-70 CE) identified the pulley as one of six simple devices used to lift weights.[3] Pulleys are assembled to create a prevent and tackle in order to give mechanical advantage to use huge forces. Pulleys are as well assembled as part of belt and chain drives so that you can transmit power from one rotating shaft to another.
The pulley, a simple machine, helps to perform work by changing the direction of forces and making easier the moving of large objects. … With this sort of pulley – known as a set pulley – pulling down on a rope makes an object go up off the ground. Additionally, there are movable pulleys and pulley devices.
