| 20080304781 | Radial Rolling Bearing, Especially Single-Row Deep Groove Rolling Bearing - The invention relates to a radial rolling bearing, especially a single-row deep groove rolling bearing, which substantially consists of an outer bearing ring and of an inner bearing ring as well as of a multitude of rollers, arranged between the bearing rings and held at uniform distances from one another in the peripheral direction by a bearing cage which is assembled from two ring halves. The rollers of the radial rolling bearing are configured in the form of spherical disks that each have two parallel lateral surfaces which are symmetrically flattened from a basic spherical shape and which roll off in two groove-type raceways with their faces. Said raceways are incorporated into the inner face of the outer bearing ring and into the outer face of the inner bearing ring. The bearing cage according to the invention is characterized by having individual cage pockets for each roller, said pockets encircling the roller on a reference line. The rollers are axially guided between the bearing rings via two low-friction line contacts between their lateral surfaces and the longitudinal webs of the cage pockets. The rollers are configured to have a defined degree of freedom for self-alignment to the pressure angle of the radial rolling bearing. | 12-11-2008 |
| 20110116734 | PUNCHED RETAINER, SELF-ALIGNING ROLLER BEARING, AND METHOD OF MANUFACTURING PUNCHED RETAINER - It is desired to form a flange and roller guide surfaces on each retainer of a self-aligning roller bearing easily and with high precision. Each punched retainer include a large-diameter annular portion ( | 05-19-2011 |
| 20120020605 | BEARING COMPONENT, ROLLING BEARING, AND METHOD FOR PRODUCING BEARING COMPONENT - An outer ring, an inner ring and a roller serving as a bearing component that adopts as a source material a steel ensuring a large fracture toughness value and also having an alloy element added thereto in a reduced amount and also provides sufficient wear resistance, are configured of a steel containing 0.15-0.3% by mass of carbon, 0.15-0.7% by mass of silicon, and 0.15-1.0% by mass of manganese, with a remainder of iron and an impurity, and have a raceway/rolling contact surface included in a region having a carbon enriched layer and a nitrogen enriched layer. In the nitrogen enriched layer the raceway/rolling contact surface has a nitrogen concentration equal to or larger than 0.3% by mass. | 01-26-2012 |

| 20150030277 | BEARING ARRANGEMENT OF A WIND TURBINE AND METHOD FOR ADJUSTING THE PRELOAD OF A BEARING ARRANGEMENT - To facilitate adjusting a bearing arrangement, particularly in a wind turbine, for different operating situations, the bearing arrangement has an adjusting device with which the bearing preload can be adjusted starting from a base preload. This can allow, for example signs of wear to be compensated, manufacturing tolerances or design inaccuracies to be corrected and in particular current loading states to be addressed. This design avoids the otherwise usual overdimensioning of the bearing arrangement, thereby increasing the efficiency of the wind turbine as well as the service life of the bearing arrangement. | 01-29-2015 |
| 20150043858 | BEARING SYSTEM AND METHOD FOR OPERATING A BEARING SYSTEM - A bearing system for supporting components that are movable relative to one another includes at least one bearing and a preload mechanism for changing a preload of the at least one bearing based on an operating state of the bearing system, where the preload mechanism includes, for example, a piezoelectric element, a Peltier element, an expansion material or a micromechanical element. | 02-12-2015 |
| 20150125104 | BEARING ARRANGEMENT FOR FLUID MACHINERY APPLICATION - A bearing arrangement for a fluid machinery application employing an axially locating bearing. The axially locating bearing includes: a first angular self-aligning contact bearing arranged next to a second angular self-aligning contact bearing. Each of the first angular self-aligning contact bearing and the second angular self-aligning contact bearing includes a set of rolling elements arranged in a row and interposed between a respective curved inner raceway and an associated curved outer raceway. Each roller is a symmetrical cylindrically-shaped roller having a curved raceway-contacting surface. Each roller is inclined respective to the axial direction of the shaft by a respective contact angle. The rollers support an axial force and a radial force. The axially non-locating bearing position is arranged spaced apart from the axially locating bearing position, as seen in the axial direction. Examples of fluid machinery applications include: a wind turbine, water turbine or a propulsion turbine. | 05-07-2015 |
| 20150139583 | BEARING UNIT FOR FLUID MACHINERY APPLICATION - A bearing unit for a fluid machinery application having a double-row bearing, the double-row bearing comprising: a first angular self-aligning contact bearing arranged next to a second angular self-aligning contact bearing for locating and rotatably support a shaft; each angular self-aligning contact bearing having a respective set of rolling elements formed of rollers arranged in a row and interposed between an associated curved inner raceway and a curved outer raceway. Each roller is a symmetrical cylindrically shaped roller having a curved raceway-contacting surface engaging with the curved inner and outer raceways. Each roller is inclined in relation to the axial direction of the shaft by a respective first or second contact angle. The rollers are arranged to cooperate with the associated curved inner and raceways for supporting an axial force and a radial force. Examples of fluid machinery applications include: wind turbine, water turbine or propulsion turbine arrangements. | 05-21-2015 |
| 20160138648 | ANGULAR CONTACT SELF-ALIGNING TOROIDAL ROLLING ELEMENT BEARING - An angular contact self-aligning toroidal roller bearing comprising an inner ring, an outer ring, and a set of rolling elements formed of rollers arranged in an intermediate configuration between the inner and outer rings. Each roller is arranged to self orient in its axial direction in relation to the inner and outer rings in a loaded zone during operation. Furthermore, a method for determining dimensional parameters of structural members of an angular contact self-aligning toroidal rolling element bearing and a method for manufacturing an angular contact self-aligning toroidal rolling element bearing are described herein. | 05-19-2016 |
