一、引言 轧机主传动系统经常承受着巨大的冲击和强烈的扭转振动,这是造成传动系统中的电机、齿轮、轴承和联轴器严重磨损和事故的主要原因,也常常是导致地脚螺丝松动断裂、机架结构以及基础本身破坏的主要原因。 目前,多数轧机的传动系统都采用传统的套筒式齿型联轴器。这种刚性传动部件对两轴对中的要求很高,在结构上也存在着传动间隙,就更加剧了传动系统中的冲击和振动,重大事故时有发生。由于钢锭重量、轧制速度和电动机功率的日益增大,有的轧机尽管安全系数取得很大,仍然发生了不少用 I. INTRODUCTION The main drive system of a rolling mill is often subjected to huge impacts and strong torsional vibrations, which are the main causes of serious wear and tear of the motors, gears, bearings and couplings in the transmission system, and often also cause the ground screws Loose fracture, the main cause of the rack structure and the destruction of the foundation itself. At present, most mill drive systems use conventional sleeve-type gear couplings. This rigid transmission parts of the two-axis alignment requirements are high, there are also in the structure of the transmission gap, the more aggravated the transmission system shock and vibration, major accidents have occurred. Due to the ingot weight, rolling speed and motor power increasing, and some mills despite the safety factor made great, still occurred a lot of use
