解放、东风等车变速器第一轴的前轴承,安装在曲轴后端的盲孔中,属于过盈配合,不易拆卸。为此,我们制作了一种专用拉具,以拆卸该轴承,现简介如下。 本拉具由锥头螺栓、膨胀套、螺母Ⅰ、螺母Ⅱ和支架所组成。 使用时,将处于原始状态的膨胀套及锥头螺栓伸入轴承内,接着旋进螺母Ⅰ.使膨胀套胀开,最后 Liberation, Dongfeng car transmission, such as the first axis of the front bearing, mounted in the blind hole at the back of the crankshaft, are interference fit, not easy to disassemble. To this end, we have produced a special pull to remove the bearing, are as follows. The puller consists of a tapered bolt, expansion sleeve, nut Ⅰ, nut Ⅱ and bracket formed. Use, the original state of the expansion sleeve and the cone head bolts into the bearing, and then screwed into the nut I. Expand the expansion sleeve, and finally
