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 belt toothhas a longitudinal cross- sectional configuration that defines a pair of spaced side facesthat respectively have free end portions thereof that are remote from adjacent rootsthereof. The teeth of the pulley and the belt are so constructed and arranged that eachbelt tooth would have the pair of free end portions thereof compressed radially
outwardly and inwardly toward each other by the respective adjacent pulley teeth if thatbelt tooth is fully received in the cavity between those respective adjacent pulley teethand those respective adjacent pulley teeth are just making contact with the land areas ofthe belt on each side of that belt tooth while being spaced from the respective roots ofthat belt tooth.
