摘要
超环面机电传动是一种有机结合电磁驱动和减速机构的空间机电传动,在机器人和航空航天等要求结构紧凑的领域具有很好的应用前景。在对该机电传动结构特点及驱动机理进行分析的基础上,对单个行星齿输出转矩进行了解析计算。通过对内外定子与行星轮的电磁啮合关系进行分析,讨论了行星轮齿数和蜗杆包角等结构参数对输出转矩的影响,推导出多齿参与啮合的输出转矩解析关系,对输出转矩的波动性做了分析计算。
The toroidal electromechanical drive is a kind of space mechanical and electrical drive with the combination of electromagnetic drive and retarding mechanism. It has a good application prospect in the field of robotics and aerospace. Based on the analysis of the structure characteristics and driving mechanism,the output torque of the single planet tooth is analytically calculated. Based on the analysis of the electromagnetic meshing relation between the internal stator and external stator and the planetary gear,the influence of the structural parameters such as the number of planet tooth and the worm wrap angle on the output torque is discussed. The analytical relationship among the output torque of multi tooth engagement is deduced. The fluctuation of the output torque is analyzed and calculated.
