我厂在加工大型发电机主轴时,因轴的自重、形状及挠度大等因素,在实际加工时,如直接将中心架搭在主轴上,很难保证主轴的形位误差要求,从而影响产品质量,为此我们从工艺工装着手,设计制造一个中心架过渡调整支承圈(如图1),来弥补直接搭中心架造成形位误差不理想的缺陷。设计时,使调整支承圈内孔稍大于轴的外径,并在其两 When machining large generator spindle, due to the weight, shape and deflection of the shaft and other factors, in the actual processing, such as the center frame directly on the spindle, it is difficult to ensure the spindle position error requirements, thus affecting the product Quality, for which we started from the process tooling, design and manufacture of a center frame transition adjustment support ring (Figure 1), to make up directly to the center frame made of shape defects error is not ideal. Design, make adjustment bearing ring hole slightly larger than the outer diameter of the shaft, and in its two
