The limit value of the steam turbine's relative differential expansion is stipulated synthetically according to the structure, material and the installational axialgap size and so on.
汽轮机相对胀差上下极限值是根据汽轮机的结构、材料、安装轴向的间隙尺寸等因素综合考虑规定的。
2
The ball screw can be pre pressed, because the pre pressure can make the axialgap reach negative value, and then get higher rigidity.
滚珠丝杠可以加预压，由于预压力可使轴向间隙达到负值，进而得到较高的刚性。

By analyzing the formula of reasonable gap for log bunk. the effects of the gap on the axial load and the adhesion of trucks and trains were elaborated.
