Power Transmission • Pulley Stock & Flanges

Pulleys are used to change the direction of an applied force and transmit rotation motion or create a mechanical advantage.

A pulley is a mechanism composed of a wheel on an axle or shaft. Between two flanges around the pulley’s circumference is a groove in which a rope, belt, cable, or chain is positioned in order to change the direction of applied force. When two or more pulleys are combined, they are referred to as a block and tackle.Pulley flanges are used to ensure that contact between belt and pulley is maintained by preventing the belt from slipping off. Constructed from metals or plastics, they fit directly onto pulleys of the same size and pitch--the distance from the midpoint of one tooth to the midpoint of the adjacent tooth.Leading manufacturers: CMT, IPG, JJC and Associates, HM Manufacturing, York Industries, Neuman, Artom, Inc.
