2.齿轮X 方向和Y 方向轴线不平行度对轮齿载荷分布的影响造成齿轮X 方向和Y 方向轴线不平行度的原因很多。除了制造精度不良外.还有以下几点:(1)齿轮箱热变形不均匀。主机隔热不良可能造成对齿轮箱体的局部辐射热,二级齿轮减速器的中间轴承座温度有可能比两端的轴承座温度高;(2)齿轮两端的支持 2. Gear X-direction and Y-axis axial non-parallelities on gear tooth load distribution caused by the gear X-axis and Y-axis axial non-parallelities for many reasons. In addition to poor manufacturing accuracy, there are the following: (1) uneven thermal deformation of the gear box. Host insulation may cause poor heat radiation of the local gear box, two-stage gear reducer intermediate bearing temperature may be higher than both ends of the bearing seat temperature; (2) both ends of the gear support
