COOLING NOZZLE FOR MOTION GUIDE DEVICE, MOTION GUIDE DEVICE WITH COOLING NOZZLE, AND COOLING SYSTEM FOR MOTION GUIDE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a cooling nozzle for a motion guide device enabling a motion guide device to be subjected to gas cooling.SOLUTION: Cooling nozzles 1a, 1b are mounted on a block 4 of a motion guide device, and cool at least one of a guide rail 2 and the block 4 assembled into the guide rail 2 in a relatively movable manner through a rolling body 6. The cooling nozzles 1a, 1b have: an internal passage 18 into which gas is introduced; an opening 12a discharging gas flow introduced into the internal passage 18; a deflection surface 22a provided adjacently to the opening 12a, and curving gas flow discharged from the opening 12a; and a guide surface 32a drawing in gas outside the cooling nozzles 1a, 1b.SELECTED DRAWING: Figure 6
