目的研究扭力矩对机构运动性能的影响．方法从理论和试验结果两方面对惯性筒加扭矩后的结果进行了分析和讨论．结果推证了复和受力蛇形槽保险机构下降运动和上升运动动力学模型．结论从提高机构远距离解除保险性能的角度出发，提出了一种新的组合受力曲折槽保险机构结构设想． Objective To study the influence of torsional moment on the movement performance of mechanism. Methods The results of the moment of inertia cylinder torque are analyzed and discussed from both theoretical and experimental standpoints. The results corroborate the descending and ascending kinetic models of complex serpentine slot insurance mechanism. Conclusion From the point of view of improving the insurance mechanism of long-distance disassembly, this paper proposes a new concept of the structure of wind-chute insurance mechanism.
