    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： 公开了一种用于替代风力涡轮机的主轴承中的油脂的方法，所述主轴承位于壳体中并且所述壳体具有至少一个盖板。 将轴承盖板从壳体中取出，将润滑脂从主轴承上手动移除，并将冲洗盖安装在壳体上以取代轴承盖板。 冲洗盖具有至少两个部件，这些部件围绕主轴装配，并且每个部件具有密封件，从而当其附接到轴承壳体时，冲洗盖与主轴形成密封。 冲洗盖有孔，可以通向主轴承，溶剂或油通过其中一个孔喷洒到主轴承上以去除油脂，其余的孔由可移除的塞子密封。 溶剂或油通过壳体底部或冲洗盖上的端口泵出壳体。 每个孔重复此过程，取下冲洗盖，主轴承装满润滑脂，并重新固定轴承盖板。 喷雾步骤包括将溶剂或油从储存器泵送到喷嘴，并且将溶剂或油泵出轴承壳体的步骤涉及通过返回软管将溶剂或油泵送到储存器。 这意味着在更换润滑脂期间溶剂或油被回收。 还描述了用于从风力涡轮机的主轴承冲洗润滑脂的装置。
