This is advantageous, since in this way the coating device 1 can be constructed in a space-saving manner even in confined spaces. For example, this allows bearing seats of wind turbines to be coated on site when installed.
- the material feed device 3 has a wire magazine 30 and at least one rotary feedthrough 31.
- the wire magazine 30 is by means of the drive rotatable by means of 11.
- the wire magazine 30 is operatively connected to the supply pipe 29.
- the wire magazine 30 has a support frame 32.
- the support frame 32 is rotatably mounted.
- each of the spray wire 29 is wound on the support frame 32.
- the spray wire 29 extends from the wire spools 33 to at least one wire feed roller, in particular to a plurality of wire feed rollers 34.
- the wire feed rollers 34 are driven by a motor.
- the material feeding device 3 has a frame 35 and a magazine carriage 36.
- the wire magazine 30 is disposed on the magazine carriage 36.
- the wire magazine 30 is rotatably mounted with the support frame 32.
- the wire magazine 30, in particular the support frame 32 is rotatably connected to a tubular body 40.
- the tubular body 40 is connected to the supply pipe 28.
- the drive means 11 is arranged on the magazine carriage 36.
- the drive means 11 is preferably designed as an electric motor and drives a belt, wherein the belt wraps around the outer circumference of the tubular body 40. As a result, the drive means 11 forms a rotary drive for the wire magazine 30.
- the rotational movement is transmitted via the supply pipe 28 to the arm 13 and thus to the spray gun 8.
- the magazine carriage 36 is arranged movably on the frame 35.
- the magazine carriage 36 has corresponding rollers 37 and at least one guide roller 38.
- the guide roller 38 engages under a corresponding guide rail 39 of the frame 35.
- the axial feed of the coating device 2 can be moved by the wire magazine 30 on the frame 35.
- the wire magazine 30 is disposed within a non-rotatable housing 41.
- the rotary leadthrough 31 is fastened to the housing 40 with a corresponding connection part. Via the rotary feedthrough 31 is gas (not shown) and el. Electricity (not shown) can be fed. The electricity is over corresponding lines led to the two spray wires 29.
- the spray gun has a nozzle 42 at one end.
- the spray wires 29 enter from the nozzle 42 in a Abschmelz Scheme.
- Abschmelz Rail (not shown in detail) is formed between the approaching spray wires 29, an arc.
- the ends of the spray wires 29 are melted in the arc.
- the molten metal particles are thrown by the gas flow on the prepared inner surface 6 of the bore 7 a, 7 b.
- spray gun 8 is rotated together with the supply pipe 28 and the wire magazine 30 and axially displaced, and simultaneously in the axial direction in the bore 7a, 7b leads, the entire inner surface 6 of the bore 7a, 7b is coated by the spray jet 43.
- the spray gun 8 is preferably interchangeable with a mechanical processing device (not shown), wherein with the mechanical processing device, a mechanical processing of the inner surface 6 is feasible.
