Pulley Calculator is a engineering calculator to calculate Belt Length, Ratio, RPM, Belt Speed, Pulley Gap. Features: - Instant calculation - Result are copy able to other apps - RPM are calculate once one of the RPM[Larger or Small] receive input - Formulas are include as reference A pulley is simply a wheel with a groove in it, and a rope in the groove. It is also called a drum or a sheave. The groove is important because it helps to keep the rope in place. It is used to lift up or lower heavy objects. With a pulley, an object to be lifted can be tied to one end of the rope, and a force is applied to the other end by pulling the rope downwards. The downward force turns the wheel with the rope and pulls the load upwards at the other end. it designed to support movement and change of direction of a taut cable or belt, or transfer of power between the shaft and cable or belt. In the case of a pulley supported by a frame or shell that does not transfer power to a shaft, but is used to guide the cable or exert a force, the supporting shell is called a block, and the pulley may be called a sheave. A pulley may have a groove or grooves between flanges around its circumference to locate the cable or belt. The drive element of a pulley system can be a rope, cable, belt, or chain.
