A pulley, composite in nature, including a fabricated wheel defining a rim channel into which a ring is positioned. The ring is rigidly held within the channel by tabs and interlocking arrangements. The ring is designed to include any one of a number of pulley gripping surfaces such as teeth and V grooves.

Pulley construction

A pulley particularly developed for timing belt systems for engines where the outer pulley surface is formed from a corrugated strip butt welded together. The resulting cylindrical ring is fixed to an inner formed wheel and conveniently positioned during assembly by tabs protruding inwardly from the cylindrical ring. The wheel is further fixed to an inner hub for placement on a shaft or the like. Protrusions on the outer surface of the wheel cooperate with recesses on the inside of the cylindrical ring to help interlock and locate the ring thereon.
