[0022] 1、 本发明通过在叶轮缸体内壁设置齿圈, 将齿圈与各行星轮啮合, 由各行星 轮带动太阳轮把增速后的旋转动能传递至发电机轴, 从而带动发电机发电。 本 发明解决了低风速下采用中速永磁直驱发电机正常运行的难题, 充分体现了速 度感与力量感, 其不仅具有节省空间、 降低成本的优点, 还极大的提高了做工 效能, 特别应用于聚风风力发电类产品吋有效降低空载启动阻力矩, 和负载转 矩脉动, 通过合理的选取永磁直驱发电机的相数、 极数和槽数, 就可以提高发 动机的运行特性, 达到低风速多发电的目的。
[0023] 2、 本发明根据项目目标地区的常年风速状况, 确定发电机的额定转速, 以狭 管聚风进口到狭管最窄处的平方面积比为依据, 由齿圈产生大扭矩、 低转速, 额定转速为 40〜50r/min,采用多个行星轮分流高扭矩带来的旋转动能, 将旋转动 能增倍 1 : 3〜1: 7, 同吋将发电机同步转速控制在 180〜250r/min的合理区间 ( 传统水平轴风机 2MW—般额定最高转速为 18r/min) , 因此可以将发电机的体积 、 重量及价格大幅度降低, 其平稳度好、 可靠性高、 系统误差少、 摩擦系数低
[0024] 3、 本发明中管式支撑箍与增强复合桥之间设置的垫圈采用高柔性胶质抗震垫 圈, 该垫圈不仅可以承担增强复合桥上几十吨重量, 并且在叶轮增速系统正常 运行吋, 能缓释叶轮增速系统旋转吋产生的离心重力, 尤其对于缓冲及抵抗恶 劣天气瞬间产生的波动性振动具有极佳效果。
[0025] 4、 本发明中通过布置毂式构件来连接叶轮缸体及管式支撑, 其具有强度高、 高承载力、 安全可靠稳定的优点。 双轨结构架的布置便于发电机的安装。 整流 罩的布置其能防止发电机在恶劣环境下淋雨受潮, 并且对来风具有整流作用。 增强复合桥对双轨结构架起支撑作用, 便于工作人员安装维修。
[0026] 5、 本发明在叶轮缸体与毂式构件的连接处布置回转轴承, 其在起到连接作用 的同吋还具有分散作用力的功能, 通过回转轴承使叶片做功的力、 叶片自身重 量及叶轮缸体的重量不再由太阳轮轴来承担, 该太阳轮轴只承担行星轮旋转吋 带给太阳轮的扭力, 使系统的整体安全性、 稳定性得到极大的提高与保障。
[0027] 6、 本发明通过布置第一刹车装置及摩擦片, 当叶轮缸体受压使摩擦片与第一 杀车装置间摩擦力增加, 从而达到刹车目的。 第二刹车装置与刹车盘抱紧实现 太阳轮轴停转的目的, 便于工作人员在吊装、 维修吋进行停车, 同吋该刹车装 置还用于风力太大防止飞车吋停机使用。

, 另一方面可以防止各行星轮及太阳轮 8转动吋润滑油飞溅。
[0029] 8、 叶轮缸体与回转轴承外圈连接处承受的重力扭矩大, 叶轮缸体在与回转轴 承外圈连接处的缸体壁厚、 加强筋厚度均要厚于叶轮缸体另一端与叶轮端盖 10 连接处的缸体壁厚, 叶轮缸体一端与回转轴承外圈的连接处的承受重力、 旋转 扭矩大于叶轮缸体另一端叶轮端盖, 使叶轮缸体形成非对称非均质缸体, 该缸 体充分突出支撑重点、 坚固静态、 动态安装工序, 在提高叶轮缸体强度的前提 下, 使叶轮缸体重量为相同功率机型的 60%。

[0060] 本发明的具体工作过程如下:
[0061] 如图 1、 图 12所示, 由于在叶片底座 12上连接叶片, 各叶片受外部风能影响驱 动叶片底座 12及叶轮缸体 11旋转, 由于叶轮缸体 11的内壁固接齿圈 2, 同吋齿圈 2与各行星轮 3啮合, 因此齿圈 2的转动驱动各行星轮 3随转, 由于各行星轮 3均与 太阳轮 8啮合, 因此外部风能通过齿圈 2、 行星轮 3及太阳轮 8转化为增速的旋转 动能, 该旋转动能通过太阳轮轴 801、 联轴器 19传递至发电机 21的输出轴, 从而 带动发电机 21发电。
[0062] 在实际运行过程中, 受各种因素变化的影响, 负荷工况变化多段, 本发明根据 项目目标地区的常年风速状况, 确定发电机的额定转速, 以狭管聚风进口到狭 管最窄处的平方面积比为依据, 由齿圈产生大扭矩、 低转速, 额定转速为 40〜5 Or/min,采用多个行星轮 3分流高扭矩带来的旋转动能, 将旋转动能增倍 1 : 3〜1: 7, 同吋将发电机同步转速控制在 180〜250r/min的合理区间 (传统水平轴风机 2 MW—般额定最高转速为 18r/min) , 因此可以将发电机的体积、 重量及价格大 幅度降低, 其平稳度好、 可靠性高、 系统误差少、 摩擦系数低, 本发明技术极 大地推动了半直驱风力机的变革和满足各种风况的安全运行特征, 也为聚风类 风力发电走出了一条全新的道路, 因此极易推广及应用。
[0063] 以上描述是对本发明的解释, 不是对发明的限定, 本发明所限定的范围参见权 利要求, 在不违背本发明的基本结构的情况下, 本发明可以作任何形式的修改
