Abstract
The bowl according to the invention is equipped with first magnetic coupling means adapted to cooperate with second complementary magnetic coupling means fixed on a non-rotary part of a sprayer, these first and second coupling means being adapted to exert an at least partially axial effort inducing the coupling in rotation of the bowl with a corresponding drive member. The radial width of an annular or truncated surface defined by the first coupling means is greater than the total radial width of the coupling means borne by the non-rotary part.
Claims19
Spraying bowl in combination with a non-rotary part and a rotary drive member for a rotary sprayer spraying coating product, the spraying bowl rotating when said rotary sprayer is in operation, wherein said spraying bowl has a first coupling surface and is equipped with first magnetic coupling means fixed on said spraying bowl for cooperating with second complementary magnetic coupling means, the second magnetic coupling means being fixed on the non-rotary part of said rotary sprayer, the non-rotary part and the second complementary magnetic coupling means being mounted to not rotate when said bowl rotates, said first and second coupling means together constituting means for exerting an at least partially axial force with respect to the axis of rotation of said bowl, said force acting to mechanically firmly couple said bowl with a corresponding second coupling surface of the rotary drive member.
Rotary sprayer for spraying coating product, comprising a bowl mounted to rotate when said rotary sprayer is in operation, said bowl having a first coupling surface, a member for driving said bowl in rotation, said member having a second coupling surface complementary to said first coupling surface, and a non-rotary part that does not rotate when said bowl is rotating,
- wherein said rotary sprayer comprises means for magnetic coupling between said bowl and said non-rotary part of said rotary sprayer, said means exerting an at least partially axial force with respect to the axis of rotation of said bowl, said force inducing a firm mechanical coupling between said first coupling surface of said bowl and said second coupling surface of said member for causing said bowl and said member to rotate as a unit, wherein said means for magnetic coupling includes a magnetic coupling element fixed on said bowl.
