根据驱动系统输出转矩之和维持不变的条件 ,导出了以主要影响因素即输送带的弹性伸长率、传动滚筒直径偏差的相对值以及电动机外特性表示的电机功率不平衡度公式·分析了电动机功率不平衡的原因和主要影响因素对功率平衡的影响规律·分析结果表明 :为了使电机功率分配相对均衡 ,在多滚筒传动的场合 ,输送带最好采用钢丝芯胶带 ;第 1滚筒的直径可以略大于第 2滚筒的直径·
According to the condition that the sum of the output torque of the drive system is kept unchanged, the formula of motor power imbalance expressed as the main influencing factors, ie the elastic elongation of the conveyor belt, the deviation of the drive roller diameter and the characteristics of the motor, is derived The reason of unbalance of motor power and the influence law of main influencing factors on power balance are analyzed. The results show that in order to make motor power distribution relatively balanced, it is better to use steel core tape in the case of multi-roller transmission. The diameter may be slightly larger than the diameter of the second roller
