Abstract

A backup ring assembly has a plurality of radially offset ring members including an outermost ring member formed from plurality of axially extending segments. Each of the plurality of axially extending segments includes an outer surface. A first interlock member support is coupled to the outer surface of one of the plurality of axially extending segments of the outer most ring member. A second interlock member support is coupled to the outer surface of an another one of the plurality of axially extending segments of the outermost ring member. An interlock member includes a first end supported at the first interlock member support and a second end supported at the second interlock member support. The interlock member restrains radially outward expansion of the ring and circumferential expansion of a gap extending between the one of the axially extending segments and the another one of the axially extending segments.

Claims (12)

What is claimed is:
1. A backup ring assembly comprising: a plurality of radially offset ring members including an outermost ring member formed from plurality of axially extending segments, each of the plurality of axially extending segments including an outer surface; a first interlock member support coupled to the outer surface of one of the plurality of axially extending segments of the outer most ring member; a second interlock member support coupled to the outer surface of an another one of the plurality of axially extending segments of the outermost ring member; and an interlock member including a first end supported at the first interlock member support, and a second end supported at the second interlock member support, the interlock member restraining radially outward expansion of the ring and circumferential expansion of a gap extending between the one of the axially extending segments and the another one of the axially extending segments.
2. The backup ring assembly according to claim 1, wherein the first interlock member support is integrally formed with the outer surface of the one of the plurality of axially extending segments and the second interlock member support is integrally formed with the adjacent one of the plurality of axially extending segments.
3. The backup ring assembly according to claim 1, wherein each of the one of the plurality of axially extending segments and the another one of the plurality of axially extending segments includes a first surface portion, a second surface portion arranged at an angle relative to the first surface portion, and a transition region arranged between the first surface portion and the second surface portion.
4. The backup ring according to claim 3, wherein the first interlock member support is coupled to the first surface portion of the one of the plurality of axially extending segments and the second interlock member support is coupled to the first surface of the another one of the plurality of axially extending segments.
5. The backup ring according to claim 4, further comprising: a third interlock member support coupled to the outer surface of the second surface portion of the one of the plurality of axially extending segments, a fourth interlock member support mounted to the outer surface of the second surface portion of the another one of the plurality of axially extending segments, and an interlock member extending between the third interlock member support and the fourth interlock member support.
6. The backup ring according to claim 4, further comprising: a fifth interlock member support coupled to the outer surface of the transition region of the one of the plurality of axially extending segments, a sixth interlock member support mounted to the outer surface of the transition region of the another one of the plurality of axially extending segments, and an interlock member extending between the fifth interlock member support and the sixth interlock member support.
7. The backup ring according to claim 1, wherein the first end of the interlock member includes a first head, and the second end of the interlock member includes a second head, the first and second heads engaging with corresponding ones of the first and second interlock member supports to limit circumferential expansion of the one of the plurality of axially extending segments relative to the another one of the plurality of axially extending segments.
8. The backup ring according to claim 1, wherein each of the plurality of radially offset ring members is formed from plurality of axially extending segments.
9. The backup ring assembly according to claim 8, wherein gaps between each of the plurality of axially extending segments in one of the radially offset ring members are circumferentially offset relative to gaps between each of the plurality of axially extending segments in an another one of the radially offset ring members.
10. The backup ring assembly according to claim 8, wherein the another one of the plurality of axially extending segments is positioned adjacent to the one of the plurality of axially extending segments.
11. The backup ring assembly according to claim 1, whereon the first end of the interlock member is moveably supported at the first interlock support.
12. The backup ring assembly according to claim 11, wherein the second end of the interlock member is moveably supported at the second interlock support.
