Abstract

A motion guide apparatus cooling nozzle is provided which can gas-cool a motion guide apparatus. Cooling nozzles 1 a and 1 b of the present invention are mounted on a block 4 of the motion guide apparatus to cool at least one of a guide rail 2 and a block 4 that is assembled to the guide rail 2 via a rolling element 6 in such a manner as to be movable relatively. The cooling nozzles 1 a and 1 b include an inner passage 18 into which gas is introduced, an opening 12 a configured to emit a gas flow introduced into the inner passage 18 , a deflection surface 22 a that is provided adjacently to the opening 12 a to bend the gas flow emitted from the opening 12 a , and a guiding surface 32 a configured to attract gas outside the cooling nozzles 1 a and 1 b.

First claim

The invention claimed is:

1. A motion guide apparatus cooling nozzle for cooling at least one of a guide rail and a block assembled to the guide rail via a rolling element in such a manner as to be movable relatively, the cooling nozzle comprising:
an inner passage into which gas is introduced;
an opening configured to emit a gas flow introduced into the inner passage;
a deflection surface, provided adjacently to the opening, to bend the gas flow emitted from the opening; and
a guiding surface configured to attract gas outside the cooling nozzle.

2. The motion guide apparatus cooling nozzle according to claim 1 , further comprising:
a center portion facing an upper surface of the guide rail; and
a leg portion facing a side of the guide rail, wherein
the opening includes the guide rail-specific opening for cooling the guide rail, and
the guide rail-specific opening includes an upper side opening placed in the center portion, and a side opening placed in the leg portion.

3. The motion guide apparatus cooling nozzle according to claim 2 , further comprising a baffle plate configured to separate a gas flow emitted from the upper side opening and a gas flow emitted from the side opening.

4. A motion guide apparatus with a cooling nozzle, comprising:
the motion guide apparatus cooling nozzle according to claim 1 ; and
the motion guide apparatus.

5. A motion guide apparatus cooling system comprising:
the motion guide apparatus cooling nozzle according to claim 1 ; and
means configured to introduce gas into the inner passage of the cooling nozzle.

6. The motion guide apparatus cooling nozzle according to claim 1 , wherein the cooling nozzle is attached to the block.

7. The motion guide apparatus cooling nozzle according to claim 6 , further comprising an inclined surface, provided adjacently to the deflection surface, to guide the gas flow emitted from the opening to at least one of the guide rail and the block.

8. The motion guide apparatus cooling nozzle according to claim 6 , further comprising:
a center portion facing an upper surface of the guide rail; and
a leg portion facing a side of the guide rail, wherein
the opening includes the guide rail-specific opening for cooling the guide rail, and
the guide rail-specific opening includes an upper side opening placed in the center portion, and a side opening placed in the leg portion.

9. The motion guide apparatus cooling nozzle according to claim 6 , wherein the opening is placed not in an inner surface, which faces the guide rail, of the cooling nozzle but in an outer surface of the cooling nozzle.

10. The motion guide apparatus cooling nozzle according to claim 9 , further comprising an inclined surface, provided adjacently to the deflection surface, to guide the gas flow emitted from the opening to at least one of the guide rail and the block.

11. The motion guide apparatus cooling nozzle according to claim 6 , wherein the opening includes
a guide rail-specific opening for cooling the guide rail, and
a block-specific opening for cooling the block.

12. The motion guide apparatus cooling nozzle according to claim 11 , further comprising an inclined surface, provided adjacently to the deflection surface, to guide the gas flow emitted from the opening to at least one of the guide rail and the block.

13. The motion guide apparatus cooling nozzle according to claim 11 , further comprising:
a center portion facing an upper surface of the guide rail; and
a leg portion facing a side of the guide rail, wherein
the opening includes the guide rail-specific opening for cooling the guide rail, and
the guide rail-specific opening includes an upper side opening placed in the center portion, and a side opening placed in the leg portion.

14. The motion guide apparatus cooling nozzle according to claim 11 , wherein the opening is placed not in an inner surface, which faces the guide rail, of the cooling nozzle but in an outer surface of the cooling nozzle.

15. The motion guide apparatus cooling nozzle according to claim 14 , further comprising an inclined surface, provided adjacently to the deflection surface, to guide the gas flow emitted from the opening to at least one of the guide rail and the block.

16. The motion guide apparatus cooling nozzle according to claim 1 , wherein the opening is placed not in an inner surface, which faces the guide rail, of the cooling nozzle but in an outer surface of the cooling nozzle.

17. The motion guide apparatus cooling nozzle according to claim 16 , further comprising an inclined surface, provided adjacently to the deflection surface, to guide the gas flow emitted from the opening to at least one of the guide rail and the block.

18. The motion guide apparatus cooling nozzle according to claim 16 , further comprising:
a center portion facing an upper surface of the guide rail; and
a leg portion facing a side of the guide rail, wherein
the opening includes the guide rail-specific opening for cooling the guide rail, and
the guide rail-specific opening includes an upper side opening placed in the center portion, and a side opening placed in the leg portion.

19. The motion guide apparatus cooling nozzle according to claim 1 , further comprising an inclined surface, provided adjacently to the deflection surface, to guide the gas flow emitted from the opening to at least one of the guide rail and the block.

20. The motion guide apparatus cooling nozzle according to claim 19 , further comprising:
a center portion facing an upper surface of the guide rail; and
a leg portion facing a side of the guide rail, wherein
the opening includes the guide rail-specific opening for cooling the guide rail, and
the guide rail-specific opening includes an upper side opening placed in the center portion, and a side opening placed in the leg portion.
