4.计算传动装置的运动和动力参数
(1) 各轴转速
= =1440/2.3=626.09r/min
= =626.09/3.24=193.24r/min
= / =193.24/2.33=82.93 r/min
= =82.93 r/min
(2) 各轴输入功率
= × =3.25×0.96=3.12kW
= ×η2× =3.12×0.98×0.95=2.90kW
= ×η2× =2.97×0.98×0.95=2.70kW
= ×η2×η4=2.77×0.98×0.97=2.57kW
则各轴的输出功率:
= ×0.98=3.06 kW
= ×0.98=2.84 kW
= ×0.98=2.65kW
= ×0.98=2.52 kW
(3) 各轴输入转矩
= × × N•m
电动机轴的输出转矩 =9550 =9550×3.25/1440=21.55 N•
所以: = × × =21.55×2.3×0.96=47.58 N•m
= × × × =47.58×3.24×0.98×0.95=143.53 N•m
= × × × =143.53×2.33×0.98×0.95=311.35N•m
= × × =311.35×0.95×0.97=286.91N•m 高校教学实践论文
输出转矩: = ×0.98=46.63 N•m
= ×0.98=140.66 N•m
= ×0.98=305.12N•m
= ×0.98=281.17 N•m
