GAS BEARINGS FOR GAS LASERS |
摘要 |
GAS BEARINGS FOR GAS LASERS An improved drive coupling and bearing assembly for a recirculation fan in a long-life gas laser unit includes a plurality of frictionless gas bearings which allow journals supporting the recirculation fan to ride on a cushion of compressed laser gas. Mechanical power is transmitted from an external source to the recirculation fan through a magnetic coupling assembly, so that the walls of the sealed laser unit do not have to be breached. Additional structure is provided for spacing the driven magnet in the magnetic coupling assembly from the interior wall of the long-life laser unit. |
