摘　　要：为了确保磨机传动系统具有足够的可靠性,避免系统停机维修而造成损失,在设计之初就对传动系统进行较全面的可靠性计算十分必要。磨机传动系统承受由转矩、扭转振动和磨机横向振动带来的载荷。通过扭振分析识别运行时的频率,结合主要激励频率绘制坎贝尔图,计算得到磨机正常工作时的转矩放大因子。根据工程经验,在工程应用中磨机故障的多发位置往往是小齿轮轴。因此,对正常工作时产生的转矩、横向载荷进行处理,分别计算不同载荷下小齿轮轴的可靠性,可以有效保证磨机的正常可靠运行,降低因小齿轮轴故障造成的损失。In order to ensure that the drive system of the mill is reliable enough to avoid the loss caused by system shutdown and maintenance,it is necessary to carry out a comprehensive reliability calculation of the drive system at the beginning of design.The mill drive system bears loads from torque,torsional vibration and transverse vibration of the mill.In this paper,the operating frequency was identified by torsional vibration analysis,and then combining the main excitation frequency,the Campbell diagram was drawn,so the torque amplification factor of the mill was calculated thereafter.According to engineering experience,the pinion shaft was the most common location of mill failures in engineering applications.Therefore,processing the torque and transverse loads generated during normal operation and calculating the reliability of the pinion shaft under different loads could effectively ensure the normal and reliable operation of the mill and reduce the loss caused by pinion shaft failures.
