Abstract
A driver for coupling a driving device and a driven device includes a core defining a plurality of corner chamfers and a casing formed on and encasing the core. The casing has a contoured perimeter surface and a variable casing thickness, and is compressible during an interference fit installation to a coupling socket to provide a non-lubricated coupling which has zero backlash and substantially no running noise. The core is made of a metal-based material and includes a shaft bore for receiving an input shaft. In an illustrative example, the driver core is made of a stainless steel core and the casing is made of a high wear thermoset urethane material. The metal core can be recycled from the coated driver by removal of the polymeric casing, then recoated with a new casing to form a new coated driver including the recycled metal core.
