摘　　要：无齿轮曳引机因节省能源、体积小、运行平稳、免维护等优点,在市场上得到广泛的应用。但电梯采用无齿轮曳引机相对于有齿轮曳引机,曳引轮和钢丝绳的使用寿命普遍要短。分析了无齿轮曳引机自身的特性,探讨了其对钢丝绳的使用寿命影响。Gearless traction machines are widely used in the elevator market due to the advantages of energy saving,small size,stable operation,and maintenance free.However,it is found that the service life of gearless machines is shorter than that of traction sheave and ropes of gear machines.The characteristics of gearless machines are analyzed and its influence on the service life of the rope is explored.

关 键 词：电梯 无齿轮曳引机 曳引轮 钢丝绳 寿命
