Abstract

A vibration isolating bushing assembly may comprise a first T-bushing configured to receive a fastener, a second T-bushing configured to couple to the first T-bushing and the fastener, a first isolating washer, and a second isolating washer, wherein the first isolating washer and the second isolating washer are configured to couple between the first T-bushing and the second T-bushing.

Claims (41)

1. A vibration isolating bushing assembly, comprising:

a first T-bushing configured to receive a fastener;

a second T-bushing configured to couple to the first T-bushing and the fastener;

a first isolating washer; and

a second isolating washer, wherein the first isolating washer and the second isolating washer are configured to couple between the first T-bushing and the second T-bushing,

wherein each of the first T-bushing and the second T-bushing comprise an annular cylindrical structure extending between a base end and a flange end, wherein a flange extends about the flange end perpendicular to the annular cylindrical structure,

wherein the flange of the first T-bushing comprises a slot, and

wherein the slot is configured to engage with a protrusion of a turbine engine component and inhibit the first T-bushing from rotating with respect to the turbine engine component.

2. The vibration isolating bushing assembly of claim 1 , wherein the annular cylindrical structure of the second T-bushing is configured to be disposed within the annular cylindrical structure of the first T-bushing.

3. The vibration isolating bushing assembly of claim 1 , wherein the annular cylindrical structure of the second T-bushing comprises a threaded surface at an inner diameter of the annular cylindrical structure.

4. The vibration isolating bushing assembly of claim 1 , wherein in response to receiving the fastener, the base end of the first T-bushing contacts the flange of the second T-bushing.

5. The vibration isolating bushing assembly of claim 1 , wherein the first isolating washer and the second isolating washer comprise a wire mesh material.

6. The vibration isolating bushing assembly of claim 1 , wherein each of the first isolating washer and the second isolating washer comprise a coupling portion configured to couple with a bushing retainer cup.

7. A gas turbine engine, comprising:

a compressor section configured to compress a gas;

a combustor section aft of the compressor section and configured to combust the gas;

a turbine section aft of the combustor section and configured to extract work from the gas;

and vibration isolator assembly, coupled between a turbine engine component and a structural member, and configured to attenuate a vibrational load from the structural member and,

wherein, the vibration isolator assembly comprises vibration isolating bushing assembly comprising:

a first T-bushing configured to receive a fastener;

a second T-bushing configured to couple to the first T-bushing and the fastener;

a first isolating washer; and

a second isolating washer, wherein the first isolating washer and the second isolating washer are configured to couple between the first T-bushing and the second T-bushing,

wherein each of the first T-bushing and the second T-bushing comprise an annular cylindrical structure extending between a base end and a flange end, wherein a flange extends about the flange end perpendicular to the annular cylindrical structure,

wherein each of the first T-bushing and the second T-bushing comprise an annular cylindrical structure extending between a base end and a flange end, wherein a flange extends about the flange end perpendicular to the annular cylindrical structure,

wherein the flange of the first T-bushing comprises a slot, and

wherein the slot is configured to engage with a protrusion of the turbine engine component and inhibit the first T-bushing from rotating with respect to the turbine engine component.

8. The gas turbine engine of claim 7 , wherein the annular cylindrical structure of the second T-bushing is configured to be disposed within the annular cylindrical structure of the first T-bushing.

9. The gas turbine engine of claim 7 , wherein the annular cylindrical structure of the second T-bushing comprises a threaded surface at an inner diameter of the annular cylindrical structure.

10. The gas turbine engine of claim 7 , wherein the first isolating washer and the second isolating washer comprise a wire mesh material.

11. The gas turbine engine of claim 7 , wherein each of the first isolating washer and the second isolating washer comprise a coupling portion.

12. The gas turbine engine of claim 11 , wherein the vibration isolator assembly comprises an elongate coupling member, wherein a bushing retainer cup is coupled to the elongate coupling member, and wherein the coupling portion is configured to couple to the bushing retainer cup.

13. The gas turbine engine of claim 7 , wherein the turbine engine component is a duct.

14. The gas turbine engine of claim 7 , wherein, in response to receiving the fastener, the base end of the first T-bushing contacts the flange of the second T-bushing.

15. An article of manufacture including a vibration isolating bushing assembly, comprising:

a first T-bushing comprising a first annular cylindrical structure extending between a first base end and a first flange end, wherein a first flange extends about the first flange end perpendicular to the first annular cylindrical structure;

a second T-bushing comprising a second annular cylindrical structure extending between a second base end and a second flange end, wherein a second flange extends about the second flange end perpendicular to the second annular cylindrical structure,

wherein, the second annular cylindrical structure is disposed within an inner diameter of the first T-bushing and wherein the second annular cylindrical structure comprises a threaded surface at an inner diameter of the second annular cylindrical structure; and

an isolating washer comprising a flexible material coupled about an outer diameter of the first annular cylindrical structure and compressed between the first flange and the second flange,

wherein the flange of the first T-bushing comprises a slot, and

wherein the slot is configured to engage with a protrusion of a turbine engine component and inhibit the first T-bushing from rotating with respect to the turbine engine component.
