BELT AND BELT DRIVE ASSEMBLY

摘要

A flexible power transmission belt used in conjunction with toothed and/or grooved pulleys of a belt drive assembly and capable of driving from opposite portions thereof. The belt includes one driving portion which is preferably transversely toothed to mesh with toothed pulleys and an opposite longitudinal plural V-ribbed driving portion which engages at least one grooved pulley. The belt is particularly useful in belt drive assemblies in which the arc of contact between the plural V-ribbed driving portion of the belt and the pulley is small or relatively small with the required high tension materially increasing stresses on the tension member of the belt.
