Abstract
A pulley construction, drive system utilizing the pulley construction and method of making the pulley construction are provided, the pulley construction being utilized with an endless drive belt and comprising a body member having a peripheral groove therein for receiving part of the belt therein and having a securing unit, and a hub member having a securing unit secured to the securing unit of the body member so as to hold the members in aligned assembled relation to rotate in unison, the hub member having structure for being interconnected to a shaft so that the pulley construction and the shaft will be adapted to rotate in unison, the securing units are so constructed and arranged that the securing unit of one of the members has a part thereof that is adapted to break away from the one member under a certain normal driving force of the belt when the shaft is prevented from rotating so as to permit relative rotational movement between the members while the securing units maintain the thus relatively rotatable members in the aligned assembled relation thereof.
