摘要

服务机器人、安防侦察车等设备移动范围大、作业空间复杂，易受撞击、堵转或外力冲击等导致过载，从而造成驱动系统齿轮折断和支撑轴弯曲，极大地限制了微小型伺服驱动系统的应用。针对该问题，提出了一种微小型减速器离合保护结构；结合有限元思想，准确地设计了离合弹簧及其保护阈值，并通过离合性能试验进行了验证。结果表明，设计的微小型减速器在过载情况下可以准确地实现离合功能；且实测的离合保护阈值与设计期望值较为吻合，可以限制齿轮承载的最大阈值，使微小型减速器的齿轮工作于设计负载范围内，提高了微小型减速器的工作可靠性。

Abstract

For service robots， security reconnaissance vehicles， etc. their mobile range is large and working space is complex. The drive system is vulnerable to impact， blocking or overload due to external impact， thereby resulting in tooth fractures and large bending of support shafts. The application of micro servo drive system is greatly limited. Aiming at this problem， a clutch structure is proposed to protect miniature reducer in this study. Using the finite element method， basic parameters of the spring and the protection threshold of the clutch structure is designed. Then， the threshold is captured and verified through the clutch performance test rig. Experimental results show that the miniature reducer can realize the clutch function accurately under the overload condition， and the measured clutch protection threshold is in good agreement with the design threshold. The clutch structure can limit the maximum threshold of the gear load， enable the gears of the miniature reducer to work within the design load range and improve the working reliability of the miniature reducer.
