摘要： A spherical roller bearing having an outer ring providing at least one inner raceway, an inner ring providing a first and a second outer raceway, a plurality of roller elements arranged in a first and second roller row in-between the at least one inner raceway and the respective first and second outer raceway is provided. The bearing provides a cage for guiding the roller elements in the first and second roller row, the cage includes a plurality of cage pockets, wherein in each cage pocket one of the roller elements is disposed. The bearing further presents a specific pitch circle diameter (PCD), and the cage is essentially in-pitch roller centered in relation to the pitch circle diameter (PCD) when there is an axial force acting on the bearing. In addition, the present invention regards a bearing arrangement and a wind turbine bearing arrangement.

摘要： A double-row spherical roller bearing, comprising an outer ring including at least one spherical inner raceway on a radially inner peripheral surface, an inner ring including a first and second axial end and at least one outer raceway on a radially outer peripheral surface. Spherical roller elements are located in first and second roller rows interposed in-between the inner and outer raceways. A first flange is located at the first axial end, extending in a circumferential direction of the outer peripheral surface. The inner ring is subjected to an axial load in a first axial direction wherein the first flange approaches the first roller row. An axial extension of the first flange extends without contacting any first roller row roller elements during bearing operation, when an axial load is acting on the inner ring in the first axial direction. The bearing can be integrated into a wind turbine.

摘要： A bearing arrangement for low speed rotating machinery includes a shaft and at least one double row spherical roller bearing supporting the shaft. The bearing has an inner ring providing a radially outer circumferential surface having a first and a second inner raceway and an annular portion separating the first and second inner raceway in an axial direction. An outer ring provides a radially inner circumferential surface with at least one outer raceway. Spherical rollers are located in a first and a second roller row, the first and second roller row disposed between the at least one outer raceway and the first and second respective inner raceway. A cage has a central portion located between the roller rows. The central portion provides a radially inner circumferential surface and axial protrusions to separate at least two rollers in one of the first and second rollers rows.
