摘　　要：为了保证偏航轴承可靠运行,在其组件上置入了径向、轴向位移和温度传感器,以在线监测轴承的运行状态,并及时对其维护或更换。介绍了传感器在轴承组件中置入的位置,并分析了置入传感器后局部结构的改变对轴承结构强度的影响,分析表明:置入传感器后轴承沟道的最大接触应力增幅为10%～15%,且轴承的最大接触应力和结构变形对轴承上传感器置入槽的高度变化比较敏感,因此,在进行轴承结构设计时,应严格确定槽高,并在设计完成后重新校核轴承的承载能力。To ensure reliable operation of the, yaw bearing, the radial displacement, axial displacement and temperature sensor are putted into the bearing assembly, so that the bearing can be on-line monitored, maintained or replaced on time. The installation location of the sensor is introduced and the effects of local structure change on structural strength of the bearing are analyzed after inserting sensor. The analysis shows that the maximum contact stress of bearing race-way increases by 10 % to 15%, and the maximum contact stress and structural deformation of the bearing is more sensitive to the height of the inserting slot for sensor. Therefore, the slot height should be strictly determined, and the load capacity of the bearing should be rechecked when designing bearing structure.
