在机器维修中有时会遇到这样一种情况:轴承损坏且散架,轴承外套镶在盲孔中无法取出。笔者为之设计了一套取套工具,只用了几分钟就将盲孔中紧压着的轴承外套取了出来。其中外套3、内套4和螺栓规格可根据轴承型号和规格选取:螺栓的有效长度应由盲孔的深度来确定,如过深则可先行垫入适当的衬铁在盲孔底部;外套3的内锥及内套4的外锥取1:5左右;外套3的最大外径以刚好能通过轴承外套2的最小径为原则,而其外圆表面形状则视轴承套的内表面而定,加工好后应以手锯开口以便于胀开。将内套4轻放入外套3小端孔中,然后将两套一并放入轴承套2孔中;以螺栓5和衬套6将内套4慢
In the machine maintenance sometimes encountered such a situation: bearing damage and Sanjia, bearing jacket set in the blind hole can not be removed. The author designed a set of tools, took only a few minutes will blind hole squeezed bearing coat taken out. The outer sleeve 3, inner sleeve 4 and bolt specifications can be selected according to the bearing type and specification: the effective length of the bolt should be determined by the depth of the blind hole. If too deep, the appropriate lining iron can be padded into the bottom of the blind hole; And the outer cone of the inner sleeve 4 is about 1: 5; the maximum outer diameter of the outer sleeve 3 is the principle that the minimum diameter of the outer sleeve 3 can pass through the outer sleeve 2; and the shape of the outer surface thereof depends on the inner surface of the bearing sleeve , After processing should be hand saw openings in order to expand. Lightly insert the inner sleeve 4 into the small end hole of the outer sleeve 3, and then put the two sleeves into the two holes of the bearing sleeve together with the inner sleeves 4
