BELL CUP FOR ROTARY ATOMIZING TYPE ELECTROSTATIC COATING DEVICE

摘要

Provided is a bell cup (11) installed on a rotation axis (CL) of a rotary atomizing electrostatic coating apparatus (1), a coating material diffusion surface (111) on an inner surface of the bell cup being supplied with a coating material, a first range (114) extending from an end part (117) of the coating material diffusion surface to a center part (116) of the coating material diffusion surface, the end part (117) being disposed toward the proximal end of the bell cup, is constituted by a convex curved surface facing towards the rotation axis; and a second range (115) extending from the center part (116) to the distal end edge (113) of the bell cup is constituted by a concave curved surface facing towards the rotation axis.
