摘要： The present invention relates to a spindle drive. A spindle drive according to an exemplary embodiment of the present invention includes: a body that is disposed at a side of a machine tool; a spindle that is disposed at the body, with a ring gear disposed thereunder; a gear box that is disposed at a side of the body; a plurality of driven shafts that is disposed at the gear box and engaged with the ring gear; an idle shaft that is disposed at the gear box and engaged with a plurality of driven gears at a side; a high-speed driving shaft that is disposed at the gear box and drives the idle shaft while changing the speed by a driving force of a spindle motor; a low-speed driving gear that is disposed at the gear box, engaged with the driven shafts, and pressed by a pressing unit such that backlash is removed; a decelerator that is disposed at the low-speed driving gear and driven by a servomotor to drive the low-speed driving gear; and a clutch unit that is disposed between the servomotor and the low-speed driving gear and controls power transmission of the servomotor.
