ABSTRACT:
The invention relates to a fluid film bearing, and more particularly the improvement of the load capacity and stability of such a bearing.
The fluid film bearing comprises a housing 7 and several bearing sub-assemblies each comprising a flexible leaf 2, a leaf reinforcing element and a support bar (5), the sub-assemblies of the bearing being fixed to the housing by insertion of each bar 5 into a groove provided in the housing. The reinforcing element comprises an upper stiffener 3 secured to the bar of a sub-assembly, and a lower stiffener 4 secued to the bar of an adjacent sub-assembly, the two stiffeners 3 and 4 overlapping on at least one part of one of their faces. The bearing is advantageously provided with a preloading spring 6.
The bearing is particularly useful in turbo engines, especially whey they form part of aircraft, more particularly military aircraft.
