某舰的螺旋桨尾轴长期处在恒定载荷作用下，虽然尾轴应力在弹性极限范围内，但是尾轴局部还是很容易发生微量的塑性变形。
Tiny deformation will appear in the local of the propeller shaft of certain ship which is endured an invariableness load, although the shaft stress is within the elastic limit range.
所以对螺旋桨尾轴进行蠕变分析是十分有意义的。
So it is significative to carry out a research on room temperature creep characteristic of propeller shaft .
全系列产品均可以匹配齿轮箱销售，部分机型可以连带尾轴，螺旋桨销售。
All Marine engines could be sold with gearbox, and some engines could be sold with tail shaft and propeller.
