V-belt pulleys (also called vee belt sheaves) are devices which transmit power between axles by the use of a v-belt, a mechanical linkage with a trapezoidal cross-section. Together these devices offer a high-speed power transmission solution that is resistant to slipping and misalignment.

V-Belt Pulleys

V-belt pulleys are used with a compatible V-belt to transmit mechanical rotating power to a shaft. The V-shaped grooves in a V-belt pulley prevent slippage and misalignment and provide maximum friction and torque in a drive system. They are found in many rotating mechanical power applications such as fans, pumps, air compressors, and conveyors.

The V-groove pulley is an indispensable transmission part for mechanical operations. Different mechanical equipment has V-groove pulleys of different specifications and sizes, especially large V-groove pulleys for large machinery are more expensive, so pay attention to maintenance. V-groove pulleys are suitable for high power and transmissions that require a compact transmission mechanism. V-groove pulleys are mainly used for long-distance transmission of power, such as small diesel engine power output, agricultural vehicles, tractors, automobiles, mining machinery, machining equipment, textile machinery, packaging machinery, lathes, forging machinery, some small horsepower motorcycles and automobiles Power transmission, agricultural machinery power transmission, air compressor, reducer, generator, cotton gin, etc.

A pulley, also known as a sheave, is a mechanism consisting of a wheel or shaft that may have a groove between two flanges around the circumference of the wheel or shaft. If present, a belt or chain usually runs over the wheels and in grooves.

Pulleys are used to change the direction of applied force, to transmit rotational motion, or to achieve mechanical advantage in linear or rotary motion systems. It is one of six simple machines. Two or more pulleys together are called a pulley block.

V-Belt Pulley Specifications

The following parameters are important when selecting v-belt pulleys.

Belt profile, or the style and sizes of the belt being integrated.

Outside diameter, or the distance across the pulley when measured between groove edges.

Center diameter is the distance or distances between the shafts of the pulleys in the transmission. V-belt transmissions are limited by center distances, which must be no more than three-times the diameter of the largest pulley, lest significant slipping can occur.

Grooves, the grooves located on the pulley, including the number, and angle and width of the flanges.

Pitch diameter, or the diameter of the pulley where the belt is engaged, and is critical to the drives strength-to-weight ratio.

Arc of contact, the degree of which the belt wraps around the pulley.

Also known as: Step Pulleys, Multi Groove Pulleys, Multi V-Pulleys, Multi V-Belt Pulleys, Cone Pulleys, Stepped Cone Pulleys.
Stepped pulleys provide a low cost and efficient means of enabling a selection of speeds. Speed changes are made when the drive is stationary, the belt tension must first be released and the belt manually relocated in an alternative set of grooves.
In many arrangements the pulley centre distance remains virtually unchanged. Stepped pulleys are produced from a one piece aluminium casting and are machined with groove profiles to accept standard V-Belts. Where the diameters allow wedge belts may also be used.
