The present invention solves a problem of a trade-off between increases in paint discharge rate and maintenance of painting quality. A rotary atomizing electrostatic applicator includes a bell cupwhose backis hit by atomization air SA-IN at an angle of 90 degrees or less; and first air holesadapted to discharge the atomization air SA-IN directed at the backof the bell cup, wherein the first air holesare arranged at equal intervals on a circumference centered around a rotation axis of the bell cup, the first air holesare oriented in a direction opposite to a rotation direction of the bell cup; and the atomization air SA-IN discharged through the first air holesis twisted in the direction opposite to the rotation direction of the bell cupat an angle of 50 degrees or more and less than 60 degrees.

Rotary atomizing electrostatic applicator and shaping air ring for the same

The rotary atomizing painting device is provided with a bell cup () disposed at the most front part in the paint spray direction X and axially supported by a rotating shaft () and a shaping air ring () disposed rearward of this bell cup () in the paint spray direction and in which a plurality of discharge openings () is formed on the periphery centered on the rotating shaft (). The plurality of discharge openings () is formed such that the axial direction of the plurality of discharge openings () is in a direction and a slant to the rotating shaft (). The axial direction of the plurality of discharge openings () is formed to aim at a back surface part (), which is a part on the back surface side of the bell cup () from the paint spray direction.
