ABSTRACT:
A one-piece metallic belt driven pulley has a hub, an annular belt engaging wall having an outer belt engaging surface and a radially extending web that connects the hub and belt engaging wall. The hub has an internal bore defined by a tubular inner surface. At least a portion of the tubular inner surface that defines the bore has a plurality of axially spaced threads to form an axially extending threaded portion. In use, the threaded portion of the bore is threaded onto an axially extending thread on an outer surface of the shaft to secure the pulley to the shaft. One end of the hub takes the form of a nut having a hexagonal outer configuration that is adapted to be engaged by a tool for screwing the pulley onto the shaft. The other end of the hub forms an axially extending integral spacer, the end of which is located outwardly of an end surface of the pulley.
