摘要： A rotary atomizing head (7) is provided with an outer peripheral surface washing passage (14) open onto anatomizing head outer peripheral surface (13) for causing wash fluid supplied from a feed tube (6) to flow out into an annular clearance (20) between the rotary atomizing head (7) and a shaping air ring (15). An outflow opening (14C1) of an outflow passage (14C) constituting the outer peripheral surface washing passage (14) is provided in a position closer to the backside into the annular clearance (20) by a length dimension (L1) than a front end surface (17A) of a front ring section (17) constituting the shaping air ring (15). Further, the outflow opening (14C1) opens to the annular clearance (20) in an angle (α1) that is an acute angle to the atomizing head outer peripheral surface (13).

摘要： The coating machine is provided with an air motor (3), a rotational shaft (4) that is rotatably supported by the air motor (3), a feed tube (5) that extends to a tip end of the rotational shaft (4) through the inside of the rotational shaft (4), a rotary atomizing head (6) that is mounted to the tip end of the rotational shaft (4), and a shaping air ring (7) that surrounds an outer periphery of the rotary atomizing head (6) and an axial tip end of which is arranged in back of a paint releasing edge (6D) of the rotary atomizing head (6). The shaping air ring (7) includes a great number of first shaping air spurting holes (9), and a great number of second shaping air spurting holes (10). An inner diameter dimension (d1) of the first shaping air spurting hole (9) is set to be larger than an inner diameter dimension (d2) of the second shaping air spurting hole (10). The number (N2) of the second shaping air spurting holes (10) is set to be smaller than the number (N1) of the first shaping air spurting holes (9).

摘要： A bearing air passage through which bearing air is supplied toward an air bearing of an air motor and a turbine air passage through which driving air is supplied toward a turbine are provided in a housing. An annular space surrounding the air motor is provided between the housing and a cover. A bearing air branch passage connecting the annular space and the bearing air passage to each other and a turbine air branch passage for connecting the annular space and the turbine air passage to each other are provided. The air branch passages lead a part of the compressed air to the annular space and keep the cover in a heated state.

摘要： A shaping air ring (10) is configured of a body (11), a cover (13) and a nozzle (15). A tapered conical protrusion (17) is provided in a front end of the nozzle (15) to abut on the cover (13) in contact therewith without a clearance therebetween. Numerous inclined recessed grooves (20) are provided on a forward tapered surfaces (17C) of the conical protrusion (17) over the entire periphery. Further, a first shaping air ejecting hole (23) is formed between each of the inclined recessed grooves (20) and an inner peripheral surface (13B2) of the cover (13) to eject shaping air toward a releasing edge (9E) of a rotary atomizing head (9). Second shaping air ejecting holes (24) are provided on an inner peripheral surface (16A) of the nozzle (15) to eject shaping air along an outer peripheral surface (9C) of the rotary atomizing head (9).
