Abstract
A rotor connection support comprising a main connection ring configured to reduce the moment load on fastener locations (such as threaded fastener locations) by integrating stand-off posts into a high strength plate are discussed herein. These stand-offs may be configured to reduce the stresses on the high stress concentration/low cross section threads. Also, included is an improved wire routing and wire support configured to maximize the fatigue cycles of the main field lead wires.
Claims10
A rotor connection ring comprising:
- a threaded stand-off configured to couple to a male threaded coupler,
- wherein the threaded stand-off comprises female threading,
- wherein at least a portion of the female threading is located above a plane defined by a top outwardly facing surface of the rotor connection ring,
- wherein the male threaded coupler comprises a wire support fastener configured to retain a wire cover,
- the wire cover is positioned at least partially overlapping a wire support,
- the wire support comprises a pair of channels configured to house two different wires, and
- the pair of channels are substantially aligned in the same axial plane.
A DC rotor system comprising:
- a connection ring comprising:
- a wire support fastener stand-off configured to couple to a wire support fastener, wherein the wire support fastener is configured to retain a wire cover, wherein wire support fastener stand-off comprises female threading, wherein at least a portion of the female threading is located above a plane defined by a top outwardly facing surface of the connection ring, and
- a wire support retained by the wire cover, wherein the wire support comprises a pair of channels configured to house two different wires wherein the pair of channels are substantially traverse the same axial plane.
A DC rotor system comprising:
- a connection ring comprising:
- a wire support fastener stand-off configured to couple to a wire support fastener, wherein the wire support fastener is configured to retain a wire cover, wherein wire support fastener stand-off comprises female threading, wherein at least a portion of the female threading is located above a plane defined by a top outwardly facing surface of the connection ring, and
- at least one of:
- a counter balance weight formed integral to the connection ring;
- and
- a DC coupler stand-off configured to couple to a male threaded coupler, wherein DC coupler stand-off comprises female threading, wherein at least a portion of the female threading is located above the plane defined by the top outwardly facing surface of the connection ring.
A DC rotor system comprising:
- a connection ring comprising:
- a wire support fastener stand-off configured to couple to a wire support fastener, wherein the wire support fastener is configured to retain a wire cover, wherein wire support fastener stand-off comprises female threading, wherein at least a portion of the female threading is located above a plane defined by a top outwardly facing surface of the connection ring, and
- a DC coupler stand-off, wherein the DC coupler stand-off and the wire support fastener standoff are configured to carry at least one of axial loads and radial loads.
