A household elevator comprises an elevator shaft and a passenger box; the inner wall of the elevator shaft is cylindrical and matched with the cylindrical passenger box, bearing rods distributed along a spiral line are arranged on the inner wall of the elevator shaft, rolling bearings are arranged on the bearing rods, and a screw capable of rotating relative to the passenger box is arranged above or below the passenger box; the radius of the addendum circle of the screw is larger than the radius of the passenger box, so that helical teeth on the screw are in contact with the outer surfaces of the bearings, and helical lines of the screw are matched with helical lines arranged on the elevator shaft bearings, so that the helical teeth of the screw can be in contact with the multiple bearings simultaneously to obtain balanced supporting force; and the screw is driven by a motor or a manual rocker to rotate relative to the passenger box so as to drive the passenger box to move up and down.
一种家用电梯,包括梯井和客箱,梯井内壁成圆筒形与圆柱形客箱匹配,梯井内壁设置沿螺旋线排布的轴承杆,轴承杆上设有滚动轴承,客箱上方或下方设有可相对客箱转动的螺杆,螺杆齿顶圆半径大于客箱半径使得螺杆上的斜齿与轴承外表面接触,螺杆的螺旋线与梯井轴承排布的螺旋线匹配使得螺杆的斜齿可以同时与多个轴承接触获得平衡的支撑力,螺杆通过电机或手动摇杆驱动使得螺杆相对客箱转动可带动客箱上下移动。
