摘　　要：本文对液压绞纲机的主轴进行了可靠性设计。可靠性设计法可以定量地回答机械产品在工作过程中的失效概率或可靠度，从而可以弥补常规设计法的不足。设计结果表明，该轴最危险截面直径取160mm就足够了，而非按常规设计的轴径为200mm。因此，采用可靠性设计方法可以得到既经济又安全的机械产品，具有较大的使用价值。Reliability designology can deal with the failure probability under working conditions of machine products and therefore compensate for the shortcomings of traditional method. The reliability design of the spindle of the hydraulic winch is discussed in this paper. Case study shows that the diameter of the critical cross-section can be reduced from 200mm to 160mm, and that the reliability design possesses even more economy and safety than that of traditional method.
