Timing Pulley Terminology Timing belts and pulleys — in order to handle a wide range of loads, speeds and applications at highest possible efciencies — are made in ve stock pitches. Circular pitch (usually referred to as pitch) is a basic consideration in the selection of timing pulleys as with gear and chain drives. Pitch is the distance between groove centers and is measured on the pulley pitch circle. On the belt, pitch is the distance between tooth centers and is measured on the pitch line of the belt. The pitch line of the belt is located within the tension member and coincides with...

Timing Pulley Terminology Timing Pulleys Timing pulleys have evenly spaced axial grooves cut in their periphery to make correct, positive engagement with the mating teeth of the belt. These pulleys are designed so that the teeth of the belt enter and leave the grooves with negligible friction. All pulleys, stock and made-to-order, have minimum tooth-to-groove clearance (backlash). The pulley’s pitch diameter will always be greater than its outside diameter. Pulleys are available in a wide range of stock widths and diameters. Minimum Pulley Diameters pitch recommended minimum* pitch diam....
