摘　　要：由于常规的力矩电机直接驱动方式难以满足大承载惯导测试与运动仿真设备的驱动要求,提出了一种基于平面二次包络环面蜗杆副及双蜗杆副相组合的消隙传动机构设计方案,并分析了该机构的结构特点及设计要素。实验结果表明:基于该机构的伺服系统达到了角秒量级的位置控制能力,运行平稳,可以满足设备的总体设计要求。Since the conventional direct-drive of torque motor is difficult to meet the design requirements of the test and motion simulation equipments for large payload, the planar double-enveloping worm pair gearing with backlash elimination was presented. The structural characteristics of the gearing mechanism and the design elements were analyzed. The experiment result shows that the system with the worm gearing reaches the position accuracy in 5arc seconds and keeps running smoothly to meet the requirement of design.
