摘　　要：以兆瓦级风电机组圆锥滚子主轴承为研究对象,建立主轴和主轴承的热结构接触计算模型,研究其在安装过程中滚道表面的Hertz接触应力、变形和温度分布规律。研究结果表明:主轴承内壁接触表面的各接触点相应的Hertz接触应力数值与主轴/主轴承的过盈量成正相关关系,与主轴壁厚/主轴承径向厚度的比值成反相关关系。Taking the tapered roller main bearing of megawatt wind turbine as the research object,the thermal structure contact calculation model of main shaft and main bearing is established,the Hertz contact stress,deformation and temperature distribution of raceway surface under the installation are studied.The results show that:the Hertz contact stress value of each contact point on the inner wall contact surface of the main bearing is in positive proportion to the interference of the main shaft/main bearing,and is inversely proportional to the ratio of the main shaft wall thickness to the main bearing radial thickness.
