COOLING NOZZLE FOR SCREW DEVICE AND COOLING NOZZLE FOR MOVEMENT-GUIDING DEVICE

摘要

There is provided a nozzle for a screw device with which it is possible to effectively gas-cool a screw device. This cooling nozzle (4) for a screw device is arranged so as to enclose at least one of a screw shaft (1) and a nut (2). The cooling nozzle (4) has an internal passage (8) into which gas is led, an opening (7) for releasing the gas flow led into the internal passage (8), a deflection surface (27) provided adjacent to the opening (7), the deflection surface (27) curving the gas flow released from the opening (7), and a guide-in channel (10) for drawing in gas from outside the cooling nozzle (4).
