Abstract

A method for manufacturing a gear includes providing a rim gear, a hub and a core wherein the core is annular and has a core forging temperature below a hot hardness temperature of the rim gear and the hub. The rim gear and the hub are rotated about an axis relative to the core. During the relative rotation, the rim gear and the hub are in contact with the core to generate friction heat to raise an interface temperature of the core to the core forging temperature. The hub is driven into the core to upset a first portion of the core into an outer annular groove defined in a first faying surface of the hub. The rim gear is driven over the core to upset a second portion of the core into an inner annular groove defined in a second faying surface of the rim gear.
