摘　　要：作为复合天轮式长冲程抽油机柔性传动件的钢丝绳，在装机试验初期的使用寿命只有400h左右。针对抽丝、断股、磨扁和剪断等失效形式，在选材、结构设计和加工制造等方面，采取一系列措施，改善了钢丝绳的抗疲劳能力，使用寿命已达到12000h以上。这些措施包括选用适当强度和直径的钢丝绳，以改善其受力状态；设计合理的天轮直径尺寸，使其与钢丝绳直径之比在50～60之间；在轮缘上镶嵌橡胶衬垫，以降低接触压力，以及钢丝绳通过销轴与横梁联接，使钢丝绳处于受拉状态等。In the light of the various failure patterns of wireline for a pumping unit with compound crown sheave, a series ofmeasures are put forward fiom such aspects as material selection, structural design and machining, thereby the fatigue re-sistance of the wireline is improved, the service life of the wireline reaches 12000 hours. The measures includes: select-ing wireline with proper strength and diameter to improve its force condition, designing rational diameter of crown sheaveto make the ratio of diameters of crown sheave and wireline being 50 ~ 60, inserting rubber liner on the sheave edge toreduce contact pressure, and making the wireline being pull by pin and cross beam connection.
