ABSTRACT:
A rotary type electrostatic spray painting device is provided with 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 in a no-contact state by a single thrust air bearing, a pair of radial air bearings, and a magnetic bearing arranged between the radial air bearings. An electrode for providing continuous electrical contact with the rear end of the rotary shaft, is cooled by being at least partially arranged in a flow path of compressed air. A negative high voltage is applied to the housing of the painting device, which is applied to the spray head via the electrode and the rotary shaft.
