以前我厂(指作者过去的工作单位长城钢厂)锻钢机的中心架升降机构及大车行走机构中,都是使用弹性圈柱销联轴器(JB106—60或ZB109—62),传递的功率为7.5kW,936r/min,大车行走机构的自重为7吨。由于锻钢机的操作工艺要求联轴器在几秒到几十秒钟的时间内作频繁的正反转,惯性力引起的冲击载荷往往使半联轴器上的锥孔磨损变形而成喇叭口,弹性圈柱销螺钉松动以至脱落,弹性圈损坏更换费时,严重的可造成减速器低速轴断裂。几年前,我们根据锻钢机的正反转冲击载荷特性,试制了嵌镶式弹性联轴器。由于降低了联轴器的扭转
Before I plant (referring to the author's past work unit Great Wall Steel) forging center frame lifting mechanism and trolley walking agencies are the use of elastic ring pin coupling (JB106-60 or ZB109-62), delivery The power of 7.5kW, 936r / min, trolley body weight of 7 tons. Due to the operation of the forging machine requires the coupling in a few seconds to dozens of seconds for frequent positive and negative rotation, the inertial force caused by the impact load is often half-coupling tapered bore wear and tear and a horn Mouth, elastic ring pin bolt loose or even fall off, elastic ring damage replacement time-consuming, serious can cause reducer low-speed shaft fracture. A few years ago, based on the positive and negative impact load characteristics of the forging machine, we made a trial of the embedded elastic coupling. Due to reduced torsion of the coupling
