Transmission Of Power By Belt And Rope Drives

A compound belt drive is used when power is transmitted on more than one shaft.
Transmission of power by belt and rope drives. Power is achieved by specially designed belts and pulleys. Types of belt drives used for power transmission and industrial application types of belt drives. A belt drive consists of two parallel shafts and a pulley is mounted on each shaft. The industrial power transmission market works with basic power transmission open drive products like belt drives chain drives gear drives and each has its own set of advantages and disadvantages.
Power transmission belts are the cheapest utility for power transmission between shafts that may not be parallel. Where power has to be transmitted between two shafts which are a distance apart a belt or rope drive is frequently used. The demands on a belt drive transmission system are large this has led to many variations on the theme. A rope drive is a form of belt drive used for mechanical power transmission.
It may be noted that the use of flat belts is limited for the transmission of moderate power from one pulley to another when the two pulley is not more than 8 metres apart. In any industrial facility turbines and motors are used to produce rotational mechanical motion to perform different kind of tasks. Rope drives use a number of circular section ropes rather than a single flat or vee belt. An endless belt runs over the surface of the pulley.
