摘要： A wind turbine rotor shaft arrangement comprising a shaft supporting wind turbine blades and a non-rotating first housing structure (mounted to a wind turbine nacelle framing) along with a first rolling bearing supporting (in a first axial direction) the shaft to the first housing structure at a first support point. The first rolling bearing is a self-aligning bearing comprising a first inner ring, a first outer ring and a set of rolling elements interposed therebetween. Each roller is asymmetric, having a curved raceway-contacting surface contacting at least one of the curved inner/outer raceways of the first inner/outer ring, respectively. A contact angle between each roller and the respective raceway is inclined respective to the shaft radial direction. A non-rotating second housing structure (mounted to the wind turbine nacelle framing) supports the shaft. A second rolling bearing supports the shaft by the second housing structure at a second support point.

摘要： 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.
摘要翻译：一种用于使用轴向定位轴承的流体机械应用的轴承装置。轴向定位轴承包括：邻近第二角度自对准接触轴承布置的第一角度自对准接触轴承。第一角度自对准接触轴承和第二角度自对准接触轴承中的每一个包括一组排列成一列的滚动元件，并且插入在相应的弯曲内滚道和相关联的弯曲外滚道之间。每个辊子是具有弯曲的轨道接触表面的对称的圆柱形辊。每个辊子相对于轴的轴向倾斜相应的接触角。滚子支撑轴向力和径向力。沿轴向方向看，轴向定位轴承位置与轴向定位轴承位置间隔开。流体机械应用的实例包括：风力涡轮机，水轮机或推进涡轮机。

摘要： 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.
