Abstract
A spindle device includes a spindle housing, a spindle shaft rotatably supported inside the spindle housing, a spindle mount having an insertion cavity into which the spindle housing is inserted along the axial direction of the spindle shaft, and a mount cover covering the spindle mount. A temperature regulator for adjusting the temperature inside the mount cover is provided inside the mount cover.
Claims11
A spindle device comprising:
- a spindle housing;
- a spindle shaft configured to be rotatably supported inside the spindle housing;
- a spindle mount having an insertion cavity into which the spindle housing is inserted along an axial direction of the spindle shaft;
- a mount cover configured to cover the spindle mount;
- and
- a temperature regulator provided inside the mount cover and configured to adjust a temperature inside the mount cover,
- wherein
- part of a seal gas supplied to a gap between a rotating member rotatably arranged on one end side of the spindle shaft in the spindle housing and a cover member covering an outer peripheral surface of the rotating member flows into a gas supply tube;
- the gas supply tube is connected to the mount cover;
- the temperature regulator includes a radiator plate fixed to an outer peripheral surface of the spindle mount;
- the radiator plate includes a first radiator piece and a second radiator piece arranged so as to be separated by a space from the first radiator piece;
- the second radiator piece is arranged closer to one end side of the spindle shaft where a rotating member rotatable in conjunction with the spindle shaft is arranged, than the first radiator piece is;
- and
- a tube through which a coolant flows is attached to the radiator plate.
