摘　　要：为提高齿轮箱的传动效率,降低功率损耗,提出了一种齿轮箱传动效率的仿真计算方法。基于KISSsys建立齿轮箱系统的传动模型,计算齿轮、轴承、轴封等损耗,并应用于双螺杆挤出机齿轮箱的传动效率分析,通过加载试验得到齿轮箱的效率数值,并与理论仿真计算的结果进行对比,结果表明仿真计算与试验结果的最大偏差为0.28%,提出的仿真计算方法能够很好的预测双螺杆挤出机齿轮箱的效率;并分析齿轮的压力角和润滑油类型对传动效率的影响,KISSsys分析结果显示齿轮压力角从20°增大到25°,齿轮的负载损耗降低了22.26%,传动效率提高了0.24%;使用聚乙二醇类合成润滑油,齿轮负载损耗平均降低了28.83%,轴承损耗平均降低了19.68%,传动效率平均提高了0.59%。In order to improve the transmission efficiency of the gearbox and reduce power loss,a simulation calculation method for the transmission efficiency of the gearbox is proposed.Establish a transmission model for the gearbox system based on KISSsys,calculate the losses of gears,bearings,shaft seals,etc.,and apply it to the transmission efficiency analysis of the twin-screw extruder gearbox.Obtain the efficiency value of the gearbox through loading experiments and compare it with the results of theoretical simulation calculations.The results show that the maximum deviation between simulation calculation and experimental results is 0.28%,and the proposed simulation calculation method can predict the efficiency of the gearbox of the twin-screw extruder well;The influence of gear pressure angle and lubricating oil type on transmission efficiency was analyzed.The KISSSsys analysis results showed that increasing the gear pressure angle from 20°to 25°reduced the load loss of the gear by 22.26%and increased the transmission efficiency by 0.24%;By using polyethylene glycol synthetic lubricating oil,the average gear load loss was reduced by 28.83%,the average bearing loss was reduced by 19.68%,and the transmission efficiency was improved by an average of 0.59%.
