Abstract: A drive turbine for a rotary atomizer, having a turbine rotor with a rotatably mounted turbine shaft. The turbine shaft is stepped along its axis of rotation with different shaft diameters, including different inner diameters and/or different outer diameters.

Abstract: The disclosure relates to a turbine drive for a rotary atomizer, having a rotatable turbine wheel with a plurality of turbine blades, a first drive nozzle for delivering a drive gas, in particular compressed air, to the turbine blades of the turbine wheel, to drive the turbine wheel, a first drive gas supply for supplying the drive gas to the first drive nozzle, and a second drive nozzle for discharging the drive gas onto the turbine blades of the turbine wheel to drive the turbine wheel. The disclosure additionally provides a second drive gas supply for supplying the drive gas to the second drive nozzle, wherein the second drive gas supply is separate from the first drive gas supply, so that the second drive nozzle can be supplied with the drive gas independently of the first drive nozzle.

Abstract: The disclosure concerns a robot hand, preferably for carrying an application apparatus preferably comprising a print head device, with a first joint structure which is rotatable about a first axis, a second joint structure which is rotatable about a second axis, and a third joint structure which is rotatable about a third axis, a line feed-through which extends through the first joint structure and through the third joint structure and preferably in which at least one line runs, and an offset between the first axis and the second axis.

Abstract: The disclosure relates to a bearing system for a drive turbine of a rotary atomizer, having a rotatable turbine shaft for receiving a bell cup which is used for spraying off the paint, and having a radial bearing for rotatably supporting the turbine shaft. The disclosure provides that the radial bearing has at least one foil bearing or a spiral groove bearing.
