Abstract
To lower the cost and weight of a belt pulley and permit its installation without the use of large numbers of spacer discs, the belt pulley is composed of two substantially identical stamped sheet metal halves which are so configured as to define a hub region when assembled. One or both of the pulley halves may be provided with a radially inwardly extending nose which engages a key-way in the shaft on which it is mounted, thereby preventing relative rotation of pulley and shaft.
