ABSTRACT:
A drive system having a toothed pulley and a cooperating toothed power transmission belt wherein the teeth of the belt are provided with transverse slots opening inwardly through the center of the tip of the tooth. The teeth are formed of resilient material, permitting the teeth to be constricted longitudinally as an incident of engagement thereof with the pulley to substantially close the slot in the engaged relationship with the pulley, thereby substantially eliminating backlash between the belt teeth and the pulley teeth, while effectively eliminating tooth deflection.
