在现代轧机传动中,棒销联轴器有逐渐取代齿轮联轴器的趋势,它比齿轮联轴器有更多的优点:构造简单、结构紧凑、不需要维修和润滑;寿命长、易损件少、易损件仅是个尼龙棒销,更换方便;易损件尼龙棒加工简单,精度要求不高,有耐磨自润滑和消振吸音性能;棒销联轴器的费用不到齿轮联轴器的10％。我厂400×2开坯轧机配套的1000kW电机和110减速机之间原来配用CL11齿轮联轴器,但寿命很低,一般用3个月即需更换,
In modern mill drives, dowel couplings have the tendency to replace gear couplings and have many advantages over gear couplings: simple construction, compact construction, no maintenance and lubrication, long life and easy wearing Less parts, wearing parts is only a nylon rod and pin, easy to replace; wearing parts of nylon rod processing is simple, less demanding precision, wear-resistant self-lubricating and vibration absorption sound performance; rod coupling costs less than gear 10% of the shaft. Our factory 400 × 2 open-air rolling mill supporting 1000kW motor and 110 reducer originally equipped with CL11 gear coupling, but life is very low, usually with 3 months to be replaced,
