摘　　要：为了分析计算单眼棉纺精梳机分离罗拉伺服驱动电机的输出转矩,基于弹性力学理论建立了后分离胶辊和分离罗拉的动力学模型,得出了分离罗拉总驱动力矩在一个工作周期内的变化规律。运用等效动力学方法建立了分离罗拉伺服驱动轮系的动力学模型,得到了伺服电机输出转矩在一个工作周期内的变化规律及伺服电机输出最大转矩和平均转矩。分析及计算结果表明:在单眼棉纺精梳机工作速度400钳次/min时,一个工作周期内伺服电机的输出转矩最大值为13.8 N·m,均值为3.6 N·m;在伺服电机输出转矩最大值中,分离罗拉驱动力矩占比为56.0%,电机转子惯性力矩占比为20.3%,过桥齿轮惯性力矩占比为18.0%。在ZGFA600型单眼棉纺精梳机上,在工作速度400钳次/min时,实测分离罗拉伺服驱动电机的实际最大输出转矩及实际平均转矩略大于理论计算值。In order to analyze and calculate output torsional torque of detaching roller servo driving motor on the monocular cotton comber,dynamical model of back detaching rubber-covered roll and detaching roller was established based on elastic mechanics,variation law of total driving torque of detaching roller in one working cycle was obtained.Dynamical model of detaching roller servo driving gear train was established by equivalent dynamics.The variation law of the servo motor output torque in one working cycle,the maximum and average output torsional torque of servo motor were obtained.The analysis and calculation results showed when the working speed of the monocular cotton comber was 400 nips/min,the maximum output torsional torque of the servo motor in one working cycle was 13.8 N·m and the average value was 3.6 N·m.Among the maximum output torsional torque of servo motor,driving torque of the detaching roller accounted was 56.0%,inertial torque of the motor rotor accounted was 20.3%and inertial torque of the carrier gear accounted was 18.0%.On ZGFA600 monocular cotton comber,when the working speed was 400 nips/min,the actual maximum output torsional torque and the actual average torsional torque of the detaching roller servo driving motor were tested,and the results obtained were slightly larger than the theoretical calculation value.
