    • 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.
    • 一种用于具有双列轴承的流体机械应用的轴承单元,所述双列轴承包括:第一角度自对准接触轴承,布置在第二角度自对准接触轴承旁边,用于定位和可旋转地支撑轴; 每个角度自对准接触轴承具有由一组排列成一列的介于相关联的弯曲内滚道和弯曲外滚道之间的辊组成的各组滚动元件。 每个辊子是一个对称的圆柱形辊子,其具有与弯曲的内部和外部滚道接合的弯曲的滚道接触表面。 每个辊相对于轴的轴向方向倾斜相应的第一或第二接触角。 辊被布置成与相关联的弯曲的内部和滚道协作以支撑轴向力和径向力。 流体机械应用的示例包括:风力涡轮机,水轮机或推进涡轮机装置。
