Abstract
For grounding or electrically charging the shaft of an electrostatic rotary atomizer working with external or direct charging, there are opposing, annular or spiral-shaped sharp edges in the outer surface of a part of the shaft and in the inner surface of a stationary bearing part at the desired potential, which have different, preferably opposite, thread directions, so that the edges intersect each other at points.
