Double V Belts
AA, BB and CC Thermoid Double v-belts are essentially Prime Mover v-belts but either side of the belt can be used as a driving surface.
Double V-belts are essentially Prime Mover Belts. Either side of the belt can be used as a driving surface. They are used on equipment where a number of shafts have to be driven in opposite directions, at the same time, by a single belt. Our Double V-belts are found on cotton gins, rock crushers, grain combines, and other machinery. The sections are AA, BB and CC (the counterparts of Prime Mover A, Band C sections). The effective pitch circumference (P.C.) of a Double V-belt is determined in exactly the same manner as the effective outside circum·ference (D.C.) of a Prime Mover belt. Thus, the effective P.C. of a BB-97 is equal to the effect ive D.C. of a B-97.
