    Abstract: A method and system for re-indexing a pitch bearing of a wind turbine includes: installing a plurality of first mounts to the fixed outer race of the pitch bearing; positioning the rotor blade to a downwardly-oriented; installing a hydraulic system; pressurizing the hydraulic system so as to support the weight of the rotor blade with the hydraulic system; detaching the rotor blade from the pitch bearing; lowering the rotor blade a predetermined vertical distance from the hub; installing a plurality of second mounts to the rotor blade; attaching a plurality of supports between the first mounts and the second mounts; transferring the weight of the rotor blade from the hydraulic system to the plurality of supports; disengaging the hydraulic system; and re-indexing the pitch bearing so as to engage a new set of pitch bearing teeth.

    Abstract translation: 用于对风力涡轮机的变桨轴承进行重新分度的方法和系统包括：将多个第一安装件安装到变桨轴承的固定外圈; 将转子叶片定位成向下定向; 安装液压系统; 对液压系统进行加压，以便利用液压系统支撑转子叶片的重量; 从变桨轴承上拆下转子叶片; 从所述轮毂将所述转子叶片降低预定的垂直距离; 将多个第二安装件安装到转子叶片上; 在所述第一安装件和所述第二安装件之间附接多个支撑件; 将所述转子叶片的重量从所述液压系统传递到所述多个支撑件; 解除液压系统; 并对变桨轴承进行重新分度，以便接合一组变桨轴承齿。
