拆卸轴承是机床修理工作中经常遇到的事。一般情况下,只要用皮带扒子就可以把轴承拆卸下来,但有时遇到如图1(轴台肩大于或等于轴承外环)及图3(轴承座孔是盲孔),皮带扒子的爪伸不进去,拉不着轴承。为此,我们根据轴承内外环都有圆角R1～1.5毫米的圆弧部分,设计了拉轴承外环、内环的工具(图1～3)。拉轴承外环时(图2),特别要注意圆弧处R1.5的加工,既不要太大,也不要太小。工具内孔与轴承外环配合为D/d,然后,铣开成两瓣,用两个螺钉联 Bearing removal is often encountered in the repair of machine tools. Under normal circumstances, as long as the belt can be used to disassemble the bearing Pa, but sometimes encountered as shown in Figure 1 (bearing shoulder greater than or equal to the outer ring) and Figure 3 (bearing hole is a blind hole) Claws can not go in, can not pull the bearings. To this end, we have designed a bearing outer ring, the inner ring of the tool (Figure 1 ~ 3), according to the circular part of the bearing inner and outer rings R1 ~ 1.5 mm. Pull the outer ring bearing (Figure 2), with particular attention to the arc R1.5 processing, neither too much nor too small. Tool bore and bearing outer ring with the D / d, then, milling into two, with two screws
