摘　　要：为满足狭窄安装环境下大行程升降机构的需求,本文设计了一种适配电动桌的紧凑型大行程升降机构,在传统螺杆/螺母升降副的基础上借助钢丝拉索机构实现了大行程两级升降,并借助分析软件ANSYS对该升降机构进行了稳定性分析.样机运行实验表明:新型升降机构能在狭窄的筒柱状桌腿内进行配装并稳定运行,其升降比接近2.5:1,是同类采用传统螺杆/螺母升降机构的1.5倍;基于该新型升降机构的电动桌,其桌面可在700 mm至1 700 mm的高度区间内任意调节,其承重载荷可达1500 N,能满足该类产品的使用要求.In order to meet the requirements of large stroke lifting mechanisms to be installed in a narrow space, this study designs a compact large stroke lifting mechanism suitable for electric tables. On the basis of conventional screw / nut lifting pair, large travel two-stage lifting is achieved using a wire cable mechanism. An analysis of the stability of the lifting mechanism is made using the software ANSYS. The prototype running testing shows the new lifting mechanism can be installed in the narrow cylinder-shaped table legs and runs stably. The lifting ratio is close to 2.5：1 and is 1.5 times of the conventional screw / nut lifting mechanism; the tabletop of the electric table fitted with the lifting mechanism can be adjusted at random between the height of 700 mm and 1700 mm, and its bearing load can be up to 1500 N and can meet the requirements for such products.
