BELL CUP FOR ROTARY ATOMIZING TYPE ELECTROSTATIC COATING DEVICE

摘要

This bell cup (11) is installed on the axis of rotation (CL) of a rotary atomizing type electrostatic coating device (1) and coating material is supplied to a coating material diffusion surface (111) on the inside surface thereof. A first span (114) from the end part (117) on the bell cup base end side to the middle part (116) of the coating material diffusion surface is constituted of a convexly shaped curved surface oriented toward the axis of rotation, and a second span (115) from the middle part (116) to the tip end edge (113) of the bell cup is constituted of a concavely shaped curved surface oriented toward the axis of rotation.
