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. 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. Each of the radial air bearings comprises a plurality of pads cooperating with the rotary shaft, and a bearing support frame supporting the pads via support pins. The bearing support frame is mounted on the outer wall of the housing via O rings. The bearing support frame and the housing are interconnected to each other by a bolt for preventing relative rotation therebetween.
