Abstract
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.
Claims20
A stub shaft comprising:
- a threaded extension configured to be received in a threaded bore of a rotary shaft;
- a mounting extension co-axial with the threaded extension and configured to receive a driven load;
- and
- a shoulder portion disposed between the threaded extension and the mounting extension, the shoulder having a load surface configured to contact an outer end surface of the rotary shaft around the threaded bore to support a moment resisting loading by the driven load.
A stub shaft system comprising:
- a rotary shaft having an inner threaded bore extending along a central axis thereof, and an outer end surface surrounding the threaded bore;
- and
- a stub shaft having a threaded extension configured to be received in the threaded bore of the rotary shaft, a mounting extension co-axial with the threaded extension and configured to receive a driven load, and a shoulder portion disposed between the threaded extension and the mounting extension, the shoulder having a load surface configured to contact the outer end surface of the rotary shaft around the threaded bore to support a moment resisting loading by the driven load.
