Abstract
A shaft extension for attachment to a crankshaft of an electric motor driven air compressor to axially extend the crankshaft for engagement with an outboard rotational bearing. The electric motor driven air compressor includes a bearing plate, an inboard rotational bearing mounted on the bearing plate, the crankshaft projecting through both of the inboard rotational bearing and the bearing plate and terminating in a distal end disposed exterior of the bearing plate. The air compressor also includes an electric motor, the electric motor having a stator frame, a stator fixedly mounted within the stator frame, and a rotor fixedly mounted to the crankshaft for rotation therewith and disposed interior of the stator. The air compressor further includes the outboard rotational bearing disposed axially outboard of the stator frame, the stator, and the rotor. The shaft extension includes an extension member having an extended major axis and a minor axis extending substantially transverse to the extended major axis and a connection mechanism for connecting the extension member to the distal end of the crankshaft.
