History. The mechanical belt drive, using a pulley machine, was first mentioned in the text the Dictionary of Local Expressions by the Han Dynasty philosopher, poet, and politician Yang Xiong (53–18 BC) in 15 BC, used for a quilling machine that wound silk fibers on to bobbins for weavers' shuttles. The belt drive is an essential component to the invention of the spinning wheel.

The drive is transferred to another pulley using a vee belt (both pulley and vee belt are shown in the image above). This type of pulley (with multiple grooves) is called a 'step pulley'. Step pulleys are used to adjust the speed of rotation of the final drive without having to take the pulley .

Idlers maintain consistent tension on belts to reduce slippage and move belts away from obstacles. Timing belt pulleys have grooves that provide maximum surface contact with the belt teeth for good power transmission and minimal slipping. V-belt pulleys provide maximum friction and torque in compatible V-belt drive systems.

Nov 13, 2013· We had three basic design constraints: 1. can it be made using a lathe or mill itself prior to the conversion and 2. low-cost and 3. relatively easy to make. Since turning v-belt pulleys takes some skill (especially if working with a smaller lathe like the 7×12 or even the 8×12), we wondered if we could use timing belt pulleys instead.

The pulley is one of the six simple machines. Basically, all that a pulley is is a wheel spinning around an axle to aid the motion of a belt. The sprockets on a bike, for example, are a type of pulley, because when they spin, they drive other sprockets on the bike, that in turn rotate the rear wheel.
