Abstract:
A spindle structure capable of accelerating the flow of a fluid in through holes of a rotor. The spindle structure includes a rotatable rotation part. The rotation part includes a tool holding part provided at an axial direction one end of the rotation part and through holes that penetrate the rotation part and open at the end in the axial direction. Further the spindle structure includes a vane provided in the through holes. When the rotation part rotates, the vane rotates with the rotation part to allow a fluid in the interior of the through holes to flow toward the end in the axial direction.

Claim (Index 1):
A spindle structure of a machine tool, comprising:\n an electric motor including a stator and a motor rotor rotatably arranged radially inside of the stator, the motor rotor having a first through hole; a spindle device arranged adjacent to the electric motor in one direction of an axial direction of the electric motor, and including a spindle housing and a spindle rotor rotatably arranged radially inside of the spindle housing, the spindle rotor being coupled to the motor rotor so as to rotate integrally with the motor rotor, the spindle rotor including:\n a tool holding part provided at an end of the spindle rotor in the one direction of the axial direction; and \n a second through hole extending through the spindle rotor so as to open at the end of the spindle rotor in the one direction of the axial direction, the second through hole being in fluid communication with the first through hole; \n a first group of fluid flow members arranged in the first through hole so as to align along the first through hole, each of the first group of fluid flow members having a plurality of vanes rotating together with the motor rotor so as to make a fluid present in the first through hole flow toward the one direction of the axial direction when the motor rotor is rotated; and a second group of fluid flow members arranged in the second through hole so as to align along the second through hole, each of the second group of fluid flow members having a plurality of vanes rotating together with the spindle rotor so as to make a fluid present in the second through hole flow toward the one direction of the axial direction when the spindle rotor is rotated.
