摘要
通过疲劳寿命计算得出三级轴瓦的疲劳寿命,对比三级轴瓦实际的失效周期,说明失效的轴瓦上的可见裂纹不是由疲劳引起的,而是由于轴与轴瓦发生干摩擦所导致的。
The fatigue life of the stage 3 bearing bush is computed, and through comparing the calculated life with the practical maintaining cycle it is found that the fatigue strength of the bearing bush is enough and the crackle on the bush surface is due to dry contact between shaft and bush.
