Document Type and Number:
WIPO Patent Application WO/2019/172665
Kind Code:
A1
Abstract:
Disclosed is a bearing screw conveying device for converting a rotational motion of a screw shaft into a linear motion by means of a bearing. The bearing screw conveying device according to the present invention comprises: a rotating screw shaft; and a first drive bearing and a second drive bearing which covert the rotational force of the screw shaft into the translational force of a movable plate disposed above the screw shaft while moving along the thread root portion of the screw shaft, wherein: a dihedral thread root portion is formed on the screw shaft; the outer ring of the first drive bearing moves along the dihedral thread root portion while coming in contact with one face of the dihedral thread root portion; the outer ring of the second drive bearing moves along the dihedral thread root portion while coming in contact with the other face of the dihedral thread root portion; and the first drive bearing and the second drive bearing are coupled symmetrically to each other in the back-and-forth direction of the movable plate while being inclined to the movable plate, whereby both the outer rings of the drive bearings are exposed in the back-and-forth direction of the movable plate.
