摘　　要：根据一起实例,从钢丝绳与曳引轮槽的匹配、轮槽磨损及钢丝绳与曳引轮包角三方面的因素,进行计算分析并找出了引起曳引力变化的原因。得出了在设计值符合国标的情况下,由于安装、使用、维护的不到位也会导致曳引系数的增大的结论,并提了相关几点改进建议。According to the case, the reason of traction capacity change is found through calculating and analyzing three factors including the match between wirerope and traction concave-groove, the abrasion of concavegroove, the cornerite between wirerope and traction wheel. Designing under GB, the conclusion shows that the traction coefficient will increase because of poor installation, using and maintenance. Some improvement suggestions are given.
