ABSTRACT:
A rotary type electrostatic spray painting device comprising a rotary shaft and a spray head fixed onto the front end of the rotary shaft. Paint is fed onto the cup shaped inner wall of the spray head. The rotary shaft is supported by a single thrust air bearing, a pair of tilting pad radial air bearings, and a single static pressure radial air bearing. The static pressure radial air bearing serves to support the rotary shaft when the rotation of the rotary shaft is stopped. An electrode, continuously contacting the rear end of the rotary shaft, is provided. A negative high voltage is applied to the housing of the paint device. In addition, the negative high voltage is also applied to the spray head via the electrode and the rotary shaft.
