<p>A double-acting power transmission belt having a plurality of elastomeric teeth positioned along both its inner and its outer peripheral surfaces, each such tooth possessing a certain spring rate, and inner and outer jackets, respectively, formed over the teeth and over the land portions between the teeth at each of the inner and outer peripheral surfaces, said inner jacket cooperating with the associated teeth such that the spring rate of each jacketed tooth on the inner one of the peripehral surfaces is from 1.2 times to 3 times the spring rate of a corresponding non-jacketed tooth.</p> |
