ABSTRACT:
A rotary type electrostatic spray painting device is comprised of a housing and a rotary shaft. The housing has an end plate having a circular hole, and the rotary shaft has a front end which passes through the circular hole. The diameter of the front end of the rotary shaft is slightly smaller than that of the circular hole thereby permitting air to pass therebetween. A spray head is fixed onto the tip of the front end of the rotary shaft at a distance from the end plate. 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 which are arranged near the rotary shaft at a hollow portion thereof. An electrode, continuously contacts the rear end of the rotary shaft to electrically connect a negative high voltage at the housing of the device to the spray head via the rotary shaft.
