Abstract

PURPOSE: To use a small diametrical screw shaft and small motor for a moving device consisting of the screw shaft and moved body side nut screwed to said screw shaft, by arranging moving speed of a moved body to resultant speed obtained from those of individual rotary speed of the screw shaft and the nut.
CONSTITUTION: To an output shaft 9 of a speed reducer 11 driven by a motor, a screw shaft 6 vertically supported with a bearing by a bracket 5 is coupled through a universal joint 7, then a nut 13 mounted to a frame 12 provided at the side part of an elevation object 1 is screwed to said screw shaft 6. To the periphery of the nut 13 a driving cylinder 18 is fixedly engaged, which is supported to a supporting cylinder 15 fixed to the frame 12 through a radial bearing 23 and thrust bearing 24. Further to the driving cylinder 18 a sprocket 28 is secured, and the nut 13 is so arranged as to be reversibly rotatably driven through a chain 31 bridged over between the sprocket and a sprocket 30 secured to a speed reduction motor 29 with a brake.
