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 and a pair of radial air bearings. A slide plate is fixed onto the rear end of the rotary shaft. An electrode, continuously contacting the slide plate, is arranged in the housing. A negative high voltage is applied to the housing of the painting device. In addition, the negative high voltage is also applied to the spray head via the electrode, the slide plate and the rotary shaft.
