An endless flexible, elastomeric or plastic power transmission belt has a series of outwardly projecting, longitudinally spaced teeth having bases integral with the belt body and an opposite free end for meshing with teeth of a pulley. The free end of each tooth is smaller in longitudinal dimension than the base and the surfaces facing adjacent teeth of the series are curved outwardly toward the adjacent teeth. The curvature is defined by the trigonometric tangent of the angles between a straight line tangent to the curvature and a straight line parallel to the base. The trigonometric tangent increases linearly from the free end of the tooth towards the base according to a constant coefficient that is a function of the mechanical characteristics of the material from which the belt is made and the dimensions of the tooth. |
