Document Type and Number:
WIPO Patent Application WO/2016/006528
Kind Code:
A1
Abstract:
Provided is a positioning device that easily responds to changes in a feed screw that is driven by a composite-oscillator-type stator. Nuts (20, 80) are connected to an inner ring (31) of a rolling bearing (30), and a stator (40) is connected to an outer ring (32) of the rolling bearing (30). As a result, the present invention is capable of responding to changes in a feed screw (a screw shaft (10) and the nut (20)) by means of changes in only output-side components such as the nut (20) that is linked to the inner ring (31).
