Abstract
A welding wire conveyor roller for conveying a welding wire includes a receiving aperture for receiving a receiving pin, and a running surface for the welding wire, and a feeding device for conveying a welding wire includes a drive motor, at least two receiving pins arranged at a distance to each other, and at least two welding wire conveyor rollers with running surfaces for the welding wire which are placed upon the receiving pins by appropriate receiving apertures. For achieving improved conveying properties even with different welding wires, an area elastically deformable in the radial direction is arranged between the running surface and the receiving aperture of the welding wire conveyor rollers.
Claims16
A welding wire conveyor roller (3, 4) for conveying a welding wire (6), comprising a receiving aperture (10) for receiving a receiving pin (8, 9) and a running surface (12) for the welding wire (6), wherein an area elastically deformable in the radial direction is arranged between the running surface (12) and the receiving aperture (10).
A feeding device (1) for conveying a welding wire (6), comprising a drive motor (2), at least two receiving pins (8, 9) arranged at a distance to each other, and at least two welding wire conveyor rollers (3, 4) with running surfaces (12) for the welding wire (6) which are placed upon the receiving pins (8, 9) by appropriate receiving apertures (10), wherein at least one welding wire conveyor roller (3, 4) comprises an area elastically deformable in the radial direction between the running surface (12) and the receiving aperture (10), and wherein the welding wire conveyor rollers (3, 4) are pressed against each other by the receiving pins (8, 9).
