ABSTRACT:
A blower wheel assembly and method is characterized by a steel hub with protruding lugs that mate with a corresponding array of holes in a backplate of the assembly. The lugs are riveted or otherwise deformed to upset the lug material, thereby permanently and securely attaching the hub to the backplate. The lugs are formed on the hub by a cold heading process whereby the hub is forcefully impacted by a heading punch or die which has recesses in it corresponding to the shape and configuration of the lugs. The impact causes the hub to deform, with the steel flowing into the recesses of the die, thus forming the lugs.
