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. An annular step portion, radially extending outwardly from the tip edge of the cup shaped inner wall of the spray head, is formed on the tip of the spray head. A thin annular tip wall axially projects from the outer periphery of the annular step portion. 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. 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.
