Abstract
An electrically insulated shaft coupling may include a first metallic portion, a second metallic portion, and an electrically insulating portion that separates the first metallic portion and the second metallic portion. The first metallic portion may include a first plurality of splines configured to interface with splines of a first rotating shaft, and the second metallic portion comprises a second plurality of splines configured to interface with splines of a second rotating shaft.
Claims17
An electrically insulated shaft coupling comprising:
- a first metallic portion, wherein the first metallic portion comprises a first plurality of splines configured to position within a first cavity of a first rotating shaft and interface with splines of the first rotating shaft;
- a second metallic portion, wherein the second metallic portion comprises a second plurality of splines configured to position within a second cavity of a second rotating shaft and interface with splines of the second rotating shaft;
- an electrically insulating portion that separates the first metallic portion and the second metallic portion;
- and
- an axial connector extending from a first end positioned in the first cavity to a second end positioned in the second cavity, wherein the axial connector is configured to axially retain the first and second metallic portions relative to each other.
