我厂是生产油泵调速器单位,调速器出厂试验时,需拆下轴承外套,非常难拆。经研究设计了拆轴承外套工具,其结构见附图。使用时,先将弹性圈1放入轴承外套与零件的间隙处,然后将冲柱2(1:5锤柱并涂些黄油)套入弹性圈内,并用锤敲打冲柱2,使其凸肩与弹性圈平面接触,此时弹性圈1便向径面扩大直径2～3mm,嵌入间隙内, Our factory is the production of pump governor units, governor factory test, the need to remove the bearing jacket, very difficult to demolish. After studying the design of the demolition bearing sleeve tool, the structure shown in the drawings. When used, put the elastic ring 1 into the gap between the bearing sleeve and the part first, then insert the punch 2 (1: 5 hammer and apply some butter) into the elastic ring and hammer the punch 2 with the hammer to make the convex Shoulder and elastic ring plane contact, then the elastic ring 1 to the diameter of the surface to expand the diameter of 2 ~ 3mm, embedded in the gap,
