Title:
電動リフト装置及び電動リフト装置を備えたロールプレス装置
Document Type and Number:
Japanese Patent JP7024857
Kind Code:
B2
Abstract:
A lifting apparatus of the present invention includes: a ball screw; a frame configured to support bearings for the ball screw; an electric motor supported by the frame and having an output shaft being rotatable; and a rotational force transferring mechanism configured to transfer a rotational force of the output shaft as a rotational force of a threaded shaft of the ball screw. A first moving body providing a first sliding surface inclined at a predetermined angle with respect to a plane including a direction of an axis is fixed to a nut of the ball screw. A second moving body is arranged to be movable linearly in a direction perpendicular to the direction of the axis with respect to the frame, has a second sliding surface configured to be slidably movable with respect to the first sliding surface, and is caused to move linearly in the direction perpendicular to the direction of the axis by a slidably movement between the first sliding surface and the second sliding surface when the nut and the first moving body moves linearly in the direction of the axis. The threaded shaft extends through the first moving body in the direction of the axis, and the pair of bearings is arranged on both sides of the first moving body.
