Cast Iron V Belt Pulley

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.
