非接触式章动减速电机一体化设计

Integrated design of a non-contact nutation speed-reduction motor

针对电机和章动减速传动机构分体使用状态下,存在着结构不紧凑、使用不便利的问题,提出并设计一种非接触式章动减速电机。该设计是探索部分零件共用实现非接触式章动传动机构与直流电机有机融合,达到进一步减少等效轴向尺寸、部分零件的目的。采用三维建模软件完成三维模型信息构建、虚拟装配等,为3D打印快速制作和调试样机提供了保证,最后对样机进行减速比实验。结果表明,该减速电机减速比稳定,也为机电集成设计提供了一种思路。

A non-contact nutation speed-reduction motor was proposed and designed to tackle problems in the separation of motor and nutation gear drive mechanism, including non-compact structure and inconvenience to use. The design was aimed to integrate the non-contact type nutation gear drive mechanism with a DC motor by sharing some parts to reduce the equivalent axial size and certain parts. 3D modelling software was employed to complete the information construction and virtual assembly of the 3D model, which can ensure the rapid prototyping and debugging of 3D printing. Finally, the reduction ratio experimentation was conducted. The results show that the speed reducing motor has a stable reduction ratio, which has provided an effective way for electromechanical integration design.
