    • The invention relates to a drive arrangement for a wind turbine, and to a wind turbine incorporating a drive arrangement. In one embodiment, a drive arrangement (12) for a wind turbine (10) is disclosed which comprises a rotor shaft (20); a gearbox assembly (22) for transferring torque from the rotor shaft to an electrical power generator (18), the gearbox assembly comprising: an input shaft (40); an output shaft (42); a primary gear stage (44); and a secondary gear stage (46), each gear stage having a plurality of planet gears (52; 58) positioned around the output shaft, an annular gear (84; 86) meshed with the planet gears, and a sun gear (82; 88) meshed with the planet gears and arranged to transfer torque to the output shaft. The drive arrangement also comprises a drive transfer mechanism (24) for transferring torque from the rotor shaft into the gearbox assembly via the input shaft; and a primary load carrying member (56) for releasably mounting the gearbox assembly to a housing (34) of the wind turbine. The rotor shaft is at least partly hollow, having an internal cavity (28) in which at least part of the gearbox assembly and at least part of the drive transfer mechanism are located. The gearbox assembly comprising the input shaft, output shaft, primary and secondary gear stages is mountable within the rotor shaft as a single unit by means of the primary load carrying member.
    • 本发明涉及一种用于风力涡轮机的驱动装置和涉及驱动装置的风力涡轮机。 在一个实施例中,公开了一种用于风力涡轮机(10)的驱动装置(12),其包括转子轴(20); 用于将扭矩从转子轴传递到发电机(18)的变速箱组件(22),所述变速箱组件包括:输入轴(40); 输出轴(42); 主齿轮级(44); 和副齿轮级(46),每个齿轮级具有围绕输出轴定位的多个行星齿轮(52; 58),与行星齿轮啮合的环形齿轮(84; 86)和太阳齿轮(82; 88)与行星齿轮啮合并布置成将扭矩传递到输出轴。 驱动装置还包括用于经由输入轴将转矩从转子轴传递到齿轮箱组件中的驱动传递机构(24) 以及用于将所述齿轮箱组件可释放地安装到所述风力涡轮机的壳体(34)的主负载承载构件(56)。 转子轴至少部分是中空的,具有内腔(28),齿轮箱组件的至少一部分和驱动传递机构的至少一部分位于其中。 包括输入轴,输出轴,初级和次级齿轮级的变速箱组件可通过主负载承载构件作为单个单元安装在转子轴内。
