摘要： A method is disclosed for replacing grease in a main bearing of a wind turbine, the main bearing located in a housing and the housing having least one cover plate. the bearing cover plate is removed from the housing, grease is manually removed from the main bearing, and a flushing cover is installed on the housing in place of the bearing cover plate. The flushing cover has at least two parts, the parts fitting around the main shaft, and each part having a seal so that when its attached to the bearing housing, the flushing cover forms a seal with the main shaft. The flushing cover has holes allowing access to the main bearing, and a solvent or oil is sprayed via one of the holes onto the main bearing to remove grease, the remaining holes being sealed by a removable plug. Solvent or oil is pumped out of the housing via a port at the bottom of the housing or flushing cover. The process is repeated for each hole, and the flushing cover removed, the main bearing packed with grease, and the bearing cover plate re-affixed. The spraying step involves pumping solvent or oil from a reservoir to the spray nozzle, and the step of pumping solvent or oil out of the bearing housing involves pumping solvent or oil to the reservoir via a return hose. This means that the solvent or oil is recycled during the replacing of the grease. An apparatus for flushing grease from a main bearing of a wind turbine is also described.
摘要翻译： 公开了一种用于更换风力涡轮机的主轴承中的润滑脂的方法，位于壳体中的主轴承和具有至少一个盖板的壳体。 将轴承盖板从壳体中取出，从主轴承上手动取出润滑脂，并且将外壳上的冲洗盖安装在轴承盖板上。 冲洗盖具有至少两个部件，部件围绕主轴安装，每个部件具有密封件，使得当其附接到轴承壳体时，冲洗盖与主轴形成密封。 冲洗盖具有允许进入主轴承的孔，并且通过一个孔将溶剂或油喷射到主轴承上以除去油脂，剩余的孔被可移除的塞子密封。 溶剂或油通过外壳或冲洗盖底部的端口从外壳中抽出。 每个孔重复该过程，拆下冲洗盖，装有油脂的主轴承和轴承盖板重新固定。 喷射步骤包括将溶剂或油从储存器泵送到喷嘴，并且将溶剂或油抽出轴承壳体的步骤包括通过返回软管将溶剂或油泵送到储存器。 这意味着溶剂或油在更换润滑脂期间被循环使用。 还描述了用于从风力涡轮机的主轴承冲洗润滑脂的装置。

摘要： An apparatus for stabilizing a shaft in an essentially horizontal position while an anchoring object at one end of the shaft is replaced without removal of an object at the opposite end of the shaft that would otherwise tend to destabilize the shaft from its essentially horizontal position includes a half-spool member configured to clamp above and around the shaft to resist torque around the rotor, under supports configured to attach to the half-spool member and clamp an underside of the shaft below the half-spool member, and a hydraulic or mechanical brake configured to resist torque on the shaft when the brake is engaged.
