摘要：A bushing and washer forming a bearing asmbly at the outer radial end of a stator vane, the outer bearing asmbly, and the bearing asmbly at the inner radial end of the stator vane, the inner bearing asmbly, that facilitate durability, effectiveness and
reduced cost. Both the inner and outer bearing asmblies are designed to rotate relative to the vane shaft and the respective mating shroud or ca to even out the wear around the circumference of the bushing. However, the bushing is designed so that if the relative wear rate between the bushing material and the vane or the shroud/ca is high, the bushing will not rotate relative to that material. When a rotating bushing is ud, a flange on the bushing is designed to be positioned on the inside of the ca, so that a pressure differential across the ca applies a force to the vane to move it outwardly against the flange and the flange against the ca, thereby minimizing air leakage. The vane is designed to have an axial bearing face adjacent to a vane stem at each end, such that the axial bearing face bears against the bushing flange or a washer to minimize wear and friction. The axial bearing face has a larger diameter for harder, less wearing materials than the adjacent bushing flange and a smaller diameter than the adjacent bushing flange for a softer, more wearing surface to minimize edge effects and “digging-in” abrasion. The sliding contact forces between the le
ver arm, vane stems and their respective shroud or ca are fully carried by the bushings and washers for the design life of the asmbly.太太的拼音
