20120301063 | SELF ALIGNING OIL FILM BEARING - An oil film bearing for rotatably supporting a shaft comprises a spherical housing having a bore in which the shaft is rotatably supported, and an outer spherical surface. A chock contains the spherical housing. The chock is internally configured with an inner spherical surface coacting with the outer spherical surface of the spherical housing to define a raceway configured to accommodate angular rotation of the shaft about a central point. | 11-29-2012 |
20140248008 | TILTING PAD RADIAL BEARING WITH AN ALIGNING DEVICE FOR A SINGLE-SHAFT TURBOMACHINE - A tilting pad radial bearing for a single-shaft turbomachine is provided having a support ring, tilting pad, and tilting pad support with an aligning device rigidly fixed to the inner face of the support ring and which has a convex sliding surface facing inwards and concave sliding surface facing outwards, the concave sliding surface rigidly fixed to the outer lying rear face of the tilting pad. The sliding surfaces lay one above the other, and each surface is a circular arc in each sliding surface longitudinal section. The aligning device keeps the axial position of the tilting pad adjustable relative to the support ring such that an angle of attack of the sliding surface of the tilting pad is adjustable relative to the axis of the tilting pad radial bearing dependent on the axial position of the concave sliding surface relative to the axial position of the convex sliding surface. | 09-04-2014 |
20140270607 | Trailing Edge Cooling On Hydrodynamic Bearings - A trailing edge cooled bearing provides an illustrative embodiment of an apparatus for increasing heat transfer in various bearings, including but not limited to radial and axial tilting pad bearings. In the illustrative embodiment, the trailing edge cooled bearing may comprise at least one journal pad having a leading and trailing edge. The trailing edge may include a trailing edge face having one or more grooves formed therein. A spray bar may having one or more apertures formed therein may be positioned adjacent the trailing edge face to deliver fluid thereto. | 09-18-2014 |
20150049969 | Radial Bearing - The invention relates to a radial bearing, comprising a housing, a housing bore extending along a bearing axis, several tilting segments that are arranged around the bearing axis in order to support a shaft and each have a radially outer bearing surface, by means of which the tilting segments are supported on a supporting surface on the housing. The radially outer bearing surface of each tilting segment and the supporting surface are arranged facing each other. Each tilting segment is movably arranged relative to the housing. The invention is characterized by the following features: a first one of the surfaces forms a first section curve with a first section plane perpendicular to the bearing axis; the first section curve is convexly curved and has a first main radius of curvature, and the second surface forms a second section curve with the section plane perpendicular to the bearing axis; the second section curve is correspondingly concavely curved and has a second main radius of curvature, wherein the magnitude of the first main radius of curvature of the first surface is smaller than the magnitude of the second main radius of curvature of the second surface; the first surface forms a third section curve with a second section plane parallel to the bearing axis; the third section curve is convexly curved and has a first secondary radius of curvature, and the second surface forms a fourth section curve with the second section plane parallel to the bearing axis; and the fourth section curve is correspondingly concavely curved or not curved and has a second secondary radius of curvature or correspondingly has no curvature, the two secondary radii of curvature being different from each other. | 02-19-2015 |
