Document Type and Number:
WIPO Patent Application WO/1989/012531
Kind Code:
A1
Abstract:
A shaft support (10), which supports both end portions of an elongated screw shaft (12) for use in moving a movable element, such as an arm of an industrial robot in a predetermined direction, is fixed to the upper surface of a base plate (14) via a gear box (30) which supports a driving motor (22) and the elongated screw shaft (12), and which contains reduction gears (24) therein, in such a manner that a projected area of the shaft support (10) on a plane perpendicular to the longitudinal direction of the elongated screw shaft (12) is reduced. When the gear box (30) is fixed to the base plate (14), a circular boss (32b), which is provided on the lower surface of the gear box (30) for use in positioning the gear box (30) in the plane of the base plate (14), and a bore (14a) provided in the base plate (14) are used. The vertical positioning of the gear box (30) is done by a positioning member (40) having a predetermined height.
