Abstract
A high-speed coupling subassembly and a high-speed overrunning clutch assembly including the subassembly are provided. The subassembly includes a powdered metal member. The member includes an axially extending coupling portion and a recess portion. The recess portion has a coupling face and a joining face spaced apart from the coupling face and being formed with a first pilot. The coupling face has at least one recess. Each of the recesses defines a load-bearing shoulder. A powdered metal hub includes an axially extending connecting portion and a mounting portion being formed with a second pilot. The mounting portion of the hub is joined to the recess portion of the member at a joint at the joining face. The first and second pilots are in contact at a pilot diameter to concentrically align the hub and the member during joining to improve performance of the assembly during a high-speed overrun condition.
