Title:
ELECTRIC SHAFT DRIVING DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/035914
Kind Code:
A1
Abstract:
The present invention relates to a driving device that rotates and linearly moves a shaft. An electric shaft driving device of the present invention is characterized by comprising: a housing; a linearly moving shaft installed to pass through the housing and be capable of linear reciprocal movement in an axial direction, and having screw threads formed on the outer periphery thereof; a clamping block installed inside the housing, and generating a magnetic field through an externally-applied power source; a first clamping plate and a second clamping plate installed to be capable of rotating and moving in an axial direction with respect to the linearly moving shaft (20) on the respective sides of the clamping block within the housing, and formed as magnetic bodies that are moved toward the clamping block and attached by means of the magnetic field generated in the clamping block; a cylindrical connecting member that connects the first clamping plate and the second clamping plate to each other and is inserted in the linearly moving shaft, and has female screw threads formed in the inner periphery thereof that screw couple to the screw threads of the linearly moving shaft; a linear driving unit that generates linear movement of the linearly moving shaft (20) in an axial direction by rotating the first clamping plate; a rotating shaft coaxially connected by a weight supporting member to one end of the linearly moving shaft, and installed to rotate with respect to the linearly moving shaft; and a rotation driving unit for rotating the rotating shaft with respect to the linearly moving shaft.
