摘要：The combination of a toothed pulley and a toothed belt and method of makingthe same are provided. The toothed belt has teeth that serially mesh with cavities of thepulley that are respectively disposed between adjacent teeth thereof. Each pulley cavityhas a longitudinal substantially trapezoidal cross-sectional configuration. Each belt toothhas a longitudinal cross-sectional configuration that defines a pair of spaced side facesthat respectively has free end portions that are remote from adjacent roots thereof andthat are spaced apart from each other by a bottom face of the tooth. The teeth of thepulley and the belt are so constructed and arranged that each belt tooth would have thepair of spaced apart free end portions thereof compressed radially outwardly andinwardly toward each other by the respective adjacent pulley teeth if that belt tooth isfully received in the cavity between those respective adjacent pulley teeth and thoserespective adjacent pulley teeth are just making contact with the land areas of the belton each side of that belt tooth while being spaced from the respective roots of that belttooth.
