Abstract: A wind-turbine gearbox system includes an input gear stage having mating gear surfaces finished to a surface roughness of less than 0.25 micron and at least one bearing supporting the input gear stage. A lubrication circuit is arranged to deliver lubricant to the input gear stage and the bearing during operation of the wind-turbine and includes an inline filter for removal of particles of less than 2 micron from the lubricant prior to delivery. A lubricant for use in the system may have a relatively low viscosity compared to conventional wind turbine gearbox lubricants.

Abstract translation: 风力涡轮机齿轮箱系统包括具有完成到小于0.25微米的表面粗糙度的匹配齿轮表面和支撑输入齿轮级的至少一个轴承的输入齿轮级。 润滑回路被布置成在风力涡轮机运行期间将润滑剂输送到输入齿轮级和轴承，并且包括在输送之前从润滑剂中除去小于2微米的颗粒的在线过滤器。 与常规风力涡轮机齿轮箱润滑剂相比，在系统中使用的润滑剂可具有相对较低的粘度。
