摘要： A bushing for aircraft landing gear includes a cylindrical wall having an interior surface defining a bore extending between a first and second axial end thereof and a cylindrical recess extending into the interior surface. The bushing includes a cylindrical self-lubricating liner which is substantially flush with the interior surface is disposed in the recess. The cylindrical wall includes a flange that has an annular recess that receives an annular self-lubricating liner that has a planar axial bearing surface. The planar axial bearing surface is coplanar with an inboard axial surface of the flange. The bushing has an electrically conductive path that conducts electrical current and that extends around the cylindrical self-lubricating liner and the annular self-lubricating liner and through the cylindrical wall and the flange.

摘要： A trunnion bearing (10) includes an inner ring (12) having exterior and interior surfaces (12E, 12K); and an outer ring (14) having interior and exterior surfaces (14K, 14E). A portion of the inner ring (12) is disposed in the outer ring (14). A lubricious liner (70) is disposed between the inner ring (12) and the outer ring (14). The trunnion bearing (10) includes a bushing (20) disposed in the inner ring (12). The bushing (20) has a first lubricant reservoir (20R) formed therein to dispense a lubricant (30) therefrom, and at least one recess (90G) in the lubricious liner (70), the at least one recess (90G) being configured as a second lubricant reservoir (90R) for dispensing a second lubricant (50) between the lubricious liner (70) and the first exterior surface (12E) of the inner ring (12).

摘要： A trunnion bearing includes an inner ring that has a first exterior surface and a first interior surface. The first exterior surface has a spherical contour. The trunnion bearing includes an outer ring that has a second interior surface and a second exterior surface. The second interior surface has a spherical contour. The inner ring is disposed at least partially in the outer ring. A metallic liner made of a copper based alloy is disposed between the first exterior surface of the inner ring and the second interior surface of the outer ring. The inner ring and/or the outer ring are made from a titanium based alloy.
