摘要 机械磨损是机械设备在使用过程中不可避免的现象,不仅会影响设备的性能,还会导致设备的失效和损坏。花键磨损和联轴器磨损均属较为常见的机械磨损故障类型。以海洋钻井平台现场遇到的几起花键磨损和联轴器磨损典型故障为例,在对故障情况及其影响进行简要介绍的基础上,对机械磨损的规律及影响因素进行了较为详细的论述,然后结合宏观检查方法及理化检测方法,对花键磨损及齿式联轴器磨损的原因进行了深入分析,据此提出合理选型与设计、更换或修复部件、润滑维护、改善安装工艺、引进新技术等改进和预防措施。 As an inevitable phenomenon during mechanical equipment operation,mechanical wear not only affects equipment performance but also leads to equipment failure and damage.Spline wear and coupling wear are common mechanical wear faults.In this study,several typical spline wear and coupling wear faults encountered in offshore drilling platforms were taken as examples.Based on a brief introduction of the faults and effects,the law and influencing factors of mechanical wear were discussed in detail.Then,the causes of spline wear and gear coupling wear were further analyzed by the combined method of macroscopic inspection and physiochemical detection.At last,improvement and prevention measures were put forward,including reasonable selection and design,replacement or repair of assembly units,lubrication,and maintenance,installation technology improvement,as well as new technology introduction.
