Document Type and Number:
WIPO Patent Application WO/2012/020997
Kind Code:
A2
Abstract:
The present invention relates to an apparatus for rotating a table of a machining tool, and more particularly, to a structure for a table-rotating apparatus in which the abrasion of a gear for driving the table in rotation is reduced and gear backlash is minimized. The apparatus for rotating a table of a machining tool according to one embodiment of the present invention comprises: a table (100) on which a workpiece is fixed; an annular table-rotating gear (110) arranged beneath the table (100); a first connection gear unit (200) which contacts one side of the table-rotating gear (110) so as to rotate the table (100); a second connection gear unit (300) which contacts the other side of the table-rotating gear (110) so as to rotate the table (100); a first driving gear (400) which contacts the first connection gear unit (200) to transmit power; a second driving gear (500) which contacts the second connection gear unit (300) to transmit power; and a driving motor (600) connected to the first driving gear (400) and to the second driving gear (500).
