Abstract
A combination flywheel, fan and pulley assembly is provided having a three piece construction, namely a central hub, at least one metal disk, and a stamped sheet metal centrifugal fan. The central hub is provided with a first circumferential surface for supporting at least one metal disk and a centrifugal fan. The hub is further provided with a bore extending at least partially through the central hub to enable the hub to be mounted on the motor shaft. The centrifugal fan has a plurality of circumferentially spaced apart radial extending blades which project axially from a generally flat face. The fan and at least one disk are securely mounted to the hub providing an integral unit. The construction method enables a wide variety of flywheel weights and hub geometries to be simply fabricated with minimal expense and production delay.
