Abstract
System for fixing a rotary spraying element to a drive rotor. According to the invention, the rotary spraying element (12) for projecting the coating product is attached to drive means (14) by means of an elastic coupling element (25). Centrifugal force increases assembly retaining force.
Claims16
Liquid coating product sprayer device comprising a rotary sprayer member (12) and drive means (14) for rotating said sprayer member, characterized in that said rotary sprayer member is attached to said drive means by an elastic coupling member (25) including at least one nesting ring (26) adapted to expand radially in response to centrifugal force and engaged with an interior annular surface of a relatively more rigid part of said rotary sprayer member or said drive means.
Tool for mounting/demounting a rotary sprayer member coupled to drive means by a nesting elastic coupling member in accordance with any one of the preceding claims characterized in that it includes a plurality of flexible clamps (63) arranged in a ring at the end of a handle, (60), each clamp including a notch (64) shaped to fit to an edge of said rotary member, and a clamping ring (65) extending coaxially around said ring and having a substantially frustoconical inside surface (67) engaged with said flexible clamps (63), said clamping ring being mobile axially relative to said ring to cause simultaneous flexing of said clamps.
