摘　　要：以MWT100-1.0 MW型风力发电机组低速输入轴轴承为例,根据轴承在全寿命周期下的设计载荷工况,基于Romax Designer仿真分析了轴承径向游隙与润滑对风机低速输入轴轴承疲劳寿命的影响,得到当径向游隙为-10~0μm、润滑油膜参数为3.21时,风机低速输入轴轴承寿命最高,并探讨了考虑径向游隙的风机低速输入轴轴承疲劳寿命预测公式。Taking low speed input shaft bearings in MWT100 - 1.0 MW type wind turbines as examples, according to design load condition of the bearings under whole life cycle, the influence of radial clearance and lubrication on fatigue life of the bearings are simulated and analyzed based on Romax Designer. It is concluded that the life of the bearings is the longest when the radial clearance is - 10 - 0 μm and the lubricating oil film parameter is 2. 437. A formula for predicting fatigue life of the bearings considering radial clearance is discussed.
