The pulley is a transmission motion organ and consists of a disk able of turn around its axis, but some models also include one or more grooves to accommodate one or more ropes, cables and similar races. Depending on the model can rotate on its axis for driving or return, or it can be keyed to a crankshaft to give movement. To vary rapidly and continously the speed of rotation of two shafts, it is possible to use a variable speed pulley, with no need to stop the transmission,. These, also known as variable-interest, are divided into two large families: - Consist of two plates which slide symmetrically on a hub, transmitting the movement to a pulley (with variation ratios through adjustment of the interest between the two pulleys) - Consisting of a pair of pulleys but with a single mobile disc that allows the variation of the speed by adjusting a wheel placed on the driving pulley. The best pulleys on the market must ensure reliability and wide range of choice, a simple assembly and high precision of execution, guaranteed by a certified production made in Italy, as well as a competitive value for money.
