Abstract

A bearing joint assembly may include a bearing sleeve, a first collar, a first mount, a pair of second mounts and a fastener, which projects through the bearing sleeve and secures the bearing sleeve to the second mounts. The bearing sleeve extends axially along a centerline and includes a spherical bearing. The first collar is configured with the bearing sleeve. A first annular channel is formed by and extends axially between the spherical bearing and the first collar. The first mount is mounted on and slidably engages the spherical bearing. The spherical bearing and the first collar are axially between the second mounts.

First claim

What is claimed is:

1 . A bearing joint assembly, comprising:
a bearing sleeve extending axially along a centerline and including a spherical bearing; a first collar configured with the bearing sleeve, wherein a first annular channel is formed by and extends axially between the spherical bearing and the first collar; a first mount mounted on and slidably engaging the spherical bearing; a pair of second mounts, the spherical bearing and the first collar axially between the second mounts; and a fastener projecting through the bearing sleeve and securing the bearing sleeve to the second mounts.

2 . The bearing joint assembly of claim 1 , wherein the first collar is mechanically attached to the bearing sleeve.

3 . The bearing joint assembly of claim 1 , wherein the first collar is bonded to the bearing sleeve.

4 . The bearing joint assembly of claim 1 , wherein the bearing sleeve comprises a first material, and the first collar comprises a second material different from the first material.

5 . The bearing joint assembly of claim 1 , wherein
the spherical bearing includes a radial outer spherical surface with a minimum radius value; and the first collar includes a radial outer collar surface with a maximum radius value that is greater than the minimum radius value of the radial outer spherical surface.

6 . The bearing joint assembly of claim 5 , wherein
the radial outer spherical surface has a maximum radius value; and the maximum radius value of the radial outer collar surface is less than or equal to the maximum radius value of the radial outer spherical surface.

7 . The bearing joint assembly of claim 5 , wherein
the radial outer spherical surface has a maximum radius value; and the maximum radius value of the radial outer collar surface is greater than the maximum radius value of the radial outer spherical surface.

8 . The bearing joint assembly of claim 1 , wherein the first collar includes a radial outer collar surface, and at least a portion of the radial outer collar surface tapers radially inwards as the first collar extends axially towards the spherical bearing.

9 . The bearing joint assembly of claim 8 , wherein the at least a portion of the radial outer collar surface is a first portion, and a second portion of the radial outer collar surface has a cylindrical geometry.

10 . The bearing joint assembly of claim 1 , further comprising:
a second collar configured with the bearing sleeve; wherein a second annular channel is formed by and extends axially between the spherical bearing and the second collar; and wherein the spherical bearing is axially between the first collar and the second collar.

11 . The bearing joint assembly of claim 1 , further comprising:
a strut comprising the first mount; and a turbine engine component comprising the second mounts.

12 . A bearing joint assembly, comprising:
a bearing sleeve extending axially along a centerline and including a spherical bearing, wherein the spherical bearing includes a radial outer spherical surface with a minimum radius value; a first collar configured with the bearing sleeve, wherein the first collar includes a radial outer collar surface with a maximum radius value that is greater than the minimum radius value of the radial outer spherical surface; a first mount mounted on and slidably engaging the spherical bearing; a pair of second mounts, the bearing sleeve and the first collar axially between the second mounts; and a fastener projecting through the bearing sleeve and securing the bearing sleeve to the second mounts.

13 . The bearing joint assembly of claim 12 , wherein the first collar is mechanically attached to and/or bonded to the bearing sleeve.

14 . The bearing joint assembly of claim 12 , wherein an annular channel is formed by and extends axially between the spherical bearing and the first collar.

15 . The bearing joint assembly of claim 12 , wherein
the radial outer spherical surface has a maximum radius value; and the maximum radius value of the radial outer collar surface is less than or equal to the maximum radius value of the radial outer spherical surface.

16 . The bearing joint assembly of claim 12 , wherein
the radial outer spherical surface has a maximum radius value; and the maximum radius value of the radial outer collar surface is greater than the maximum radius of the radial outer spherical surface.

17 . A bearing joint assembly, comprising:
a bearing sleeve extending axially along a centerline and including a spherical bearing; a first collar mechanically attached to and/or bonded to the bearing sleeve, wherein a first annular channel is formed by and extends axially between the spherical bearing and the first collar; a second collar configured with the bearing sleeve, wherein a second annular channel is formed by and extends axially between the spherical bearing and the second collar; and a linkage including a first mount slidably engaged with the spherical bearing, wherein the spherical bearing is captured within an aperture extending axially through the first mount.

18 . The bearing joint assembly of claim 17 , wherein the second collar is mechanically attached to and/or bonded to the bearing sleeve.

19 . The bearing joint assembly of claim 17 , wherein the bearing sleeve comprises a first material, and the first collar comprises a second material different from the first material.

20 . The bearing joint assembly of claim 17 , wherein
the spherical bearing includes a radial outer spherical surface with a minimum radius value; and the first collar includes a radial outer collar surface with a maximum radius value that is greater than the minimum radius value of the radial outer spherical surface.
