【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。更多还原

【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.更多还原
