摘　　要：为提高板式定量输送机启动和加速时运行的稳定性和安全性,对链传动系统的驱动力的计算问题进行了研究。采用逐点计算法求得链传动系统稳定运行工况下的最大静张力,提出采用多轴电力拖动系统的折算方法,将直线移动部分和旋转部分的惯性阻力折算到驱动轴得出加速载荷,由最大静张力和加速载荷确定最大驱动力。结果表明,加速载荷约为最大驱动力的35%,计算驱动功率及破断力时除考虑保持运行的最大静张力外,必需考虑加速载荷的影响。For improving the stability and security when the plate quantitative conveyor start-up and the accelerating operation,the calculation problem of driving force of chain drive system is studied.The maximum static tension of the chain drive system on stable operating conditions is calculated by point by point calculation method.The multi-axis electric drive system conversion method is proposed and the acceleration load is calculated by converted the inertial resistance of linear moving parts and rotating parts to drive shaft.The maximum driving force is sum of maximum static tension and the acceleration load.The results show that,the acceleration load account for the driving force about 35%,the drive power and breaking force calculation is necessary to consider the impact of the acceleration load in addition to the maximum static tension.
