一般对外锥内圆结构滑动轴承的修理,都是先以床头箱孔为基准,在轴承放松的情况下把外圆刮好,再把主轴装入轴承,收紧轴承,进行刮配,直到刮好为止。这样,内圆虽是圆的,但外圆却由于不均匀的收缩而变成椭圆了,造成轴承与床头箱孔的接触不良,影响接触刚度,从而影响加工光洁度。我们采用了锁紧轴承,使其内孔等于主轴轴径时与床头箱孔刮配,这样就消除了轴承外圆的椭圆度,解决了轴承与床头箱的接触刚度问题。为达到此目的,我 General external cone internal structure of the sliding bearing repair, are first bedside box hole as a benchmark in the case of relaxation of the outer cylindrical scraping, and then the spindle into the bearing, tighten the bearing, scraping with until Shave so far. In this way, although the inner circle is round, but the outer circle due to uneven shrinkage and become oval, resulting in poor contact between the bearing and the bedside box hole, affecting the contact stiffness, thus affecting the processing finish. We use a locking bearing, so that the bore is equal to the spindle shaft diameter with the bed box hole scraping, thus eliminating the outer diameter of the bearing ovality, to solve the bearing and headstock contact stiffness problem. For this purpose, I
