ABSTRACT:
A power transmission belt having a load carrying band with a length, and a plurality of blocks attached to the load carrying band at preselected, spaced intervals along the length of the load carrying band. The plurality of blocks have a thickness (t), measured in a direction along the length of the load carrying band, and a width (W), measured in a direction transversely to the length of the load carrying band. Each of the plurality of blocks is made from synthetic resin material and has no shape-determining insert therein. The synthetic resin material is made from a synthetic resin having a bending modulus of 15 to 20 GPa. The ratio of t/W is from 0.11 to 0.20.
