摘要：

本文以大庆Ⅰ—130钻机绞车为例,以钻速曲线和起升曲线为前提,推算出绞车各挡链条所传递的当量功率,并对部分链条进行了疲劳寿命计算。从理论上提出了当置功率的折算和链条疲劳寿命计算的新方法。

关键词： 钻机;绞车;链条;寿命;疲劳

Abstract: The paper, taking a winch of Daqing I-130 drilling machines as an exam-ple, presupposing drilling velocity curves and lifting curves, develops equi-valent power transported by chains for every gear and fatigue life of partsof the chains.The paper theoretically mentions new methods which convert equivalentpower and work out fatigue life of chains.

Keywords: drilling machine;winch;chain;fatigue
