    Abstract: A bearing system includes a bearing housing that includes a sleeve and a mounting structure for connecting the bearing system to a compressor housing. The sleeve has a radial inner surface that defines a cylindrical bore, and includes a locking feature located along the radial inner surface. The mounting structure is located radially outward from the sleeve. The bearing system also includes a foil bearing assembly positioned within the cylindrical bore. The foil bearing assembly includes an outer foil, an inner foil, and a bump foil positioned between the outer foil and the inner foil. At least one of the outer foil and the inner foil includes a bearing retention feature cooperatively engaged with the locking feature to maintain the foil bearing assembly within the bearing housing at a fixed rotational position.

    Abstract: A bearing system includes a bearing housing and a foil bearing assembly. The bearing housing includes a sleeve that defines a cylindrical bore and includes at least one bearing assembly locking feature, and a mounting structure. The foil bearing assembly includes an outer foil assembly, an inner foil assembly, and a bump foil assembly positioned between the outer foil assembly and the inner foil assembly. The outer foil assembly includes at least one outer foil pad that extends circumferentially from a first end including a bearing retention feature to a second end. The bearing retention feature is cooperatively engaged with the at least one bearing assembly locking feature. The inner foil assembly includes a plurality of circumferentially-spaced inner foil pads. Each inner foil pad extends circumferentially from a tab to a free end. At least one inner foil pad is welded to the outer foil assembly along the tab.
