| 20090116780 | Bearing Systems - Bearing arrangements are described which enable rotation about a vertical axis with a very extended diameter bearing, for example 20 meters diameter. A usually stationary base supports a rotating member, e.g. on a fluid cushion. Separately, a ring of radially adjustable arcuate surface support pads on an outer member acts against a cylindrical surface of an inner member. The adjustability of the radially movable support pads enables them to increase their thrust at parts of the circumferences of the bearing relative to others. This enables considerably smoother running to be achieved, both to compensate for the difficulties of producing complete circularity with a bearing diameter of substantial size, and for varying direction lateral loadings, e.g. as experienced by a vertical axis wind-driven turbine. | 05-07-2009 |

The apparatus has a transmitter for electromagnetic radiation, and a receiver for the radiation emitted by the transmitter. A space-saving and simple apparatus for detecting the load on the bearing ring of the bearing is achieved, by virtue of the fact that an optical waveguide is provided, into which the transmitter couples the electromagnetic radiation, and by virtue of the fact that the optical waveguide is arranged on a surface of the at least one bearing ring, and by virtue of the fact that the at least one bearing ring is in the region of an evanescent field coming from the optical waveguide.

| 20090285518 | AXIAL ROLLING BEARING - The invention relates to an axial rolling bearing having a cage which contains rolling bodies that are arranged between two running disks. The running disks each have a radial section that forms a raceway and an axially aligned collar which adjoins the raceway. The collars are aligned opposite to one another and overlap in the axial direction. The radially outer disk has a larger diameter than the radially inner running disk. According to the invention, the radial and the axial extent of the two collars of the running disks and the cage are coordinated with one another in such a way that, between them, a labyrinth seal, composed of a plurality of gaps, is formed, and the cage is guided on the collar of the radially inner running disk. | 11-19-2009 |
| 20100278473 | CAGE FOR ROLLER BODIES - A cage for roller bodies, for example axial bearings or flat guides, which is approximately W-shaped in the longitudinal cross-section, having side walls forming W-shaped limbs and webs connecting them, between which the roller bodies are accommodated. The profile of the webs is suitable for limiting the freedom of movement of the roller bodies to at least two degrees of freedom. Furthermore, the profile of the webs is designed such that the freedom of movement of the roller bodies can be limited in at least one additional degree of freedom. | 11-04-2010 |
| 20090041402 | THRUST BEARING ASSEMBLY - A thrust bearing assembly generally includes a cage and a plurality of rolling elements. The cage has first and second cage halves with each cage half having a respective radial segment with a plurality of circumferentially spaced openings. Each opening has an opening perimeter. The cage halves are interconnected with portions of the radial segments circumferentially between the plurality of openings abutting along a given plane and the respective openings aligned to defined rolling element pockets. The rolling elements are positioned in the rolling element pockets such that a centerline of each rolling element lies in or in proximity to the given plane. A flange extends along at least a portion of each opening perimeter to retain the rolling elements within a respective one of the rolling element pockets. | 02-12-2009 |
| 20100303401 | THRUST BEARING - In a thrust bearing, an axially outer end portion of each pin of a pin-type retainer is fixed to an outside ring by a weld, and a threaded shaft, formed at an axially inner end portion of each pin, is screwed into a threaded hole formed in an inside ring. An inner peripheral surface of the inside ring slides on an outer peripheral surface of a rotary shaft, whereby the rotation of the pin-type retainer is guided, | 12-02-2010 |

| 20120076451 | THRUST BEARING ASSEMBLY - A thrust bearing assembly having a plurality of rollers positioned in a cage is provided. A first race washer is positioned on a first axial side of the rollers and the cage, with the first race washer including a first axially extending flange axially overlapping the cage and the rollers, and having at least one protrusion extending in a direction away from the cage. A first retention band including a first axially extending band and a first retaining flange that extends radially from the first axially extending band is provided. The first retention band has at least one recess or opening and is complementary in size to the first race washer flange and engagable thereon. Engagement is accomplished via the at least one protrusion on the first axially extending flange engaging the at least one recess or opening in the first retention band. The first retaining flange has a width that is sized to overlap a portion of the cage on a second axial side. A second race washer and second retention band can be provided for a fully encapsulated thrust bearing assembly | 03-29-2012 |
| 20110274385 | AXIAL ROLLER BEARING CAGE WITH INCREASED CAPACITIES - The axial roller bearing cage has an inner ring, an outer ring, and a plurality of alternating cage bars and roller pockets, which are formed between the inner ring and the outer ring. The roller pockets of the axial roller bearing cage extend along the entire length of the cage bars, accommodating rollers of maximum length, which also enables a compact cage design for a given roller length. The cage enhances the friction characteristics between the ends of the rollers and the cage bars. The ends of the rollers are supported on a centerline, which reduces frictional torque by reducing the length of the frictional moment arm on each roller, allowing for a symmetric loading. The ends of the rollers are also supported by the inboard smooth surface of the formed flanges of the connecting elements, which increases oil film development and allows the bearing to operate at higher speeds. | 11-10-2011 |
