PURPOSE:To obtain a beautiful painted surface with pulverized spray paint and prevent the entry of a thinner into the device by improbing a supporting mechanism for a revolving shaft provided with a paint ejection part, etc. thereby obtaining high revolutions in a titled device used for painting the bodies of automobiles, etc. CONSTITUTION:A revolving shaft 8 which is built in a rotary atomization device 1 and is in contact with an electrode 66 for application of negative voltage to paint at all times is supported by noncontact type radial bearings 22, 23 and a noncontact type thrust bearing consisting of runners 39, 40 and an annular plate 44. The shaft 8 is supported by the compressed air ejected by at least one of these radial bearings 22, 23, and thrust bearings 39, 40, 44. This ejected air is ejected through a through- hole 86 having a micro-annular spacing, by which the entry of paint into a housing 2 is prevented. Since the shaft 8 is revolved at high speeds by using such support mechanism, etc. the spray paint is pulverized, and the beautiful surface is obtained. Also, the occurrence of a fire owing to a thinner is prevented. |
