ABSTRACT:
A drive assembly for rotating a shaft of a pulley driven device. The drive assembly includes a hub in the form of an annular body of ferrous metal having a groove in an external periphery thereof. A belt driven pulley is provided in the form of ferrous sheet metal and has a web portion. A structural connection is defined between the hub and the pulley web portion such that the hub is in fixed, abutted relation with the pulley web portion. The hub and the pulley web portion have a bore therethrough defining a single, machined annular surface. The annular surface is constructed and arranged to engage a periphery of the shaft in an interference-fitted manner so as to maintain torque transfer to the shaft in the event of failure of the structural connection. The groove is constructed and arranged to be operatively engaged by a pulling tool for removing the annular surface from engagement with the shaft.
