摘　　要：使用温压成形技术制造的粉末冶金斜齿轮耐磨性好,成本低。利用有限元法建立了包含齿轮副、传动轴、轴承和箱体的齿轮系统完整的动力学模型。计算了在动态激励下粉末冶金斜齿轮系统的振动响应,通过试验验证了有限元分析模型;研究了粉末冶金斜齿轮传动效率特性,分析了材料因素对齿轮传动效率的影响。结果表明:粉末冶金斜齿轮传动效率比38CrMoAl斜齿轮高,传动更平稳,磨损小,因而具有广阔的应用前景。The powder metallurgy helical gears manufactured in warm compaction technique have good wearability and low cost. The integrated dynamics model, which includes gear pair, transmission shaft, bearing and gearbox, has been built using finite element method. The vibration response of the helical gear transmission system on dynamic excitation has been calculated. The finite element analysis model has been verified by experiment. The efficiency of the powder metallurgy helical gear is higher than that of 38CrMoAl helical gear, at the same time, it works more steadily, with better lubricating capability and less abrasion when meshing. It has wide applying foreground.
