摘　　要：谐波减速器具有传动平稳、传动精度和传动效率高、传动比范围大、承载能力高、结构简单、体积小、质量轻等优点,被广泛应用于航空航天、工业机器人、精密医疗等领域。目前,国内外谐波减速器刚轮材料多采用球墨铸铁和合金钢,刚轮制造多采用慢走丝、滚齿或插齿工艺,效率低,成本高,而采用粉末冶金法制备的材料尚未在谐波齿轮中应用。鉴于此,本工作将铁基Fe-Ni-Mo-Cu-C粉末冶金材料用于谐波减速器刚轮的制备,采用面摩擦磨损试验机对材料的摩擦磨损性能进行研究。白光干涉形貌、光学显微镜、扫描电镜和500 h台架实验的测试结果表明,粉末冶金法制备的Fe-Ni-Mo-Cu-1.0C材料具有优异的摩擦磨损性能,能够满足谐波减速器刚轮的使用要求。Harmonic gear drive is widely used in aerospace,industrial robots,precision medical and other fields,owing to its excellent properties,such as stable transmission,high transmission accuracy and efficiency,a wide range of transmission ratio,high bearing capacity,simple structure,small volume,light weight and so on.The material of rigid gear for harmonic gear drive at home and abroad is mostly ductile cast iron and alloy steel,and the rigid gear is mainly manufactured through low speed wire cut,gear hobbing or gear shaping,which have the disadvantages of low efficiency and high cost.The material prepared by powder metallurgy has not been applied in harmonic gear drive.This work herein proposed the application of Fe-Ni-Mo-Cu-C material made through powder metallurgy process in rigid gear of harmonic gear drive.The friction and wear properties of the mentioned powder metallurgy material were studied by the surface friction and wear tester.According to the results of white-light interference morphology,optical microscopy(OM),scanning electron microscope(SEM)and 500 h bench test measurement,the Fe-Ni-Mo-Cu-1.0C material prepared by powder metallurgy has excellent friction and wear performance,which can meet the requirements of rigid gear for harmonic gear drive.
