Flange shouldered screw-in stub shaft

摘要

A stub shaft arrangement is provided for mounting loads on rotary shafts, such as the rotor shaft of an electric motor. The stub shaft has a load mounting extension, a threaded extension, and a shoulder disposed therebetween. The threaded extension is designed to interface with a threaded bore of a rotary shaft to secure the stub shaft in place. The shoulder bears tightly against an outer or end surface of the rotary shaft to resist overhung loads on the stub shaft. The arrangement of the shoulder permits a greater distance to be obtained for a moment that resists the loading.
