v-belt pulley specification pdf

Typically, v-belt drives operate between 1,500 to 6,000 ft/min, with 4,500 ft/min the ideal capacity for standard belts. Some narrow v-belts can operate at speeds of up to 10,000 ft/min, but these pulleys must be dynamically stabilized.

Single or multiple grooves V-belt pulley. Variable Speed. Pulley faces or flanges adjust axially to vary pitch diameter. Idler. The pulley contains bearing to rotate freely; used as belt tensioner. Companion. Companion pulleys have ribbed webs for high strength-to-weight ratio. Step. Step pulleys include multiple size pulleys in a step-down or

A pulley consists of a wheel turning on a fixed axle, with a groove along the edges to guide a rope or cable. It is also known as a machine made with a rope, chain or belt wrapped around a grooved wheel. A pulley modifies the direction of the force, making it easier to lift things. It is a system of ropes and wheels that achieve the purpose of making an object easier to lift.
