ABSTRACT:
A toothed belt and belt-adapted pulley system provides a high-load capacity and increased durability by reducing stress concentrations on dedendum portions and further preventing localized bending of belt tensile cords. Smooth engagement of elastic teeth of a belt is possible due to minimization of interference between the elastic teeth upon engagement or disengagement with a pulley. Reduced vibration, low noise, and a reduction in skipping under high loads result from the inventive system. Each tooth of the belt has a peripheral length m.sub.0 and a dedendum portion with a length m.sub.1, where m.sub.1 /m.sub.0 is 0.1 or less. Each tooth of the pulley has a peripheral length n.sub.0 and a dedendum portion having a length n.sub.1, where n.sub.1
.sub.0 is 0.1 or less.
