摘要:
The invention relates to a gear wheel pump with two meshing gear wheels which are rotatably mounted within a pump housing by means of a driven driveshaft and a crankshaft journal and which form a pumping channel system between a pump inlet and a pump outlet. Several gaps are formed between the pump housing, the gear wheels, the driveshaft, and the crankshaft journal. One of the gaps between the driveshaft and one of the gear wheels contains means for the rotationally fixed connection of the driveshaft to the gear wheel. In order to prevent leakages penetrating to the connecting means, according to the invention the gap between the driveshaft and the gear wheel is sealed, with respect to the front faces of the gear wheel, by means of a sealant.

The invention relates to a coating device, in particular for painting motor vehicle bodies, comprising a sprayer (1) for applying a coating material by means of an application element and an internal color-changer valve assembly (3), said assembly having several color inlets (4-7) for selecting coating materials of different colors. The internal color-changer valve assembly (3) is integrated into the sprayer (1) and is connected by its outlet to the application element (2), in order to feed the selected coating material to the application element (2). The invention also comprises an external color-changer valve assembly (14) with several color inlets for selecting coating materials of different colors, said external color-changer assembly (14) having a separate structure from the sprayer (1) and being connected by its outlet to the application element (2), in order to feed the selected coating material to the application element (2). The invention also relates to a corresponding operating method.
摘要:
For grounding or electrically charging the shaft of an electrostatic rotary atomizer working with external or direct charging, there are opposing, annular or spiral-shaped sharp edges in the outer surface of a part of the shaft and in the inner surface of a stationary bearing part at the desired potential, which have different, preferably opposite, thread directions, so that the edges intersect each other at points.

The invention concerns a method for controlling a robot or a first robot (LR1) and at least one further second robot (LR2), wherein the robot or the first robot (LR1) and the at least one further second robot (LR2) is provided to run through a plurality of positioning ranges (SB11, SB22) during operation. Preferably, a dynamic behavior and/or a load characteristic value of the robot in at least one first positioning range is adapted to a dynamic behavior and/or a load characteristic value in at least one second positioning range of the robot and/or a dynamic behavior and/or a load characteristic value of the first robot (LR1) in at least one first positioning range (SB11) is adapted to a dynamic behavior and/or a load characteristic value of the second robot (LR2) in at least one second positioning range (SB22). The invention further concerns a corresponding control system, a corresponding computer program resp. computer-readable medium and a corresponding robot.
摘要:
A method and apparatus for smoothing a surface of a component, e.g., of large structures, as for example ship hulls for subsequent painting, is disclosed. An exemplary method may include measuring an unevennesses of the surface of the component, levelling the unevennesses by material removal and/or by material application of a levelling mass, adding reference markings at certain locations on the surface to be measured before the measurement of the surface, and taking account of the reference markings during the measurement of the unevennesses of the surface.
摘要:
An application robot, specifically a painting robot, for coating workpieces with a coating medium and an appropriate operating method. The painting robot has multiple movable axes and a spatially positionable end effector. Multiple application devices are attached to the end effector.
摘要:
A coating material supply device is disclosed, such as for a paint facility. An exemplary coating material supply device may include a coating material reservoir and a coating material meter. During application of coating material, the coating material reservoir may be at ground potential and may be located upstream from the coating material meter, which may be at a high-voltage potential. The reservoir may be connected via an insulating path to the coating material meter. The coating material meter may be at ground potential when the coating material reservoir supplies coating material to the coating material meter. Before the coating material meter is returned to a high-voltage potential for continued application of coating material, the insulating path may be emptied to insulate the coating material meter from the coating material reservoir.
摘要:
Exemplary painting devices for painting components, e.g., motor vehicle bodies or parts thereof, and associated exemplary methods are disclosed. An exemplary painting device may include a multi-axis painting robot positioning an atomizer, a robot controller for controlling the painting robot, and a controls enclosure comprising the robot controller. An exemplary controls enclosure may be a load-bearing column that mechanically supports the painting robot.
摘要:
A painting station, e.g., for serially painting components such as motor vehicles, is disclosed. A painting station may include at least one painting cell in which components are coated, e.g., with a paint, that has a certain layer thickness. At least one measuring cell is provided for measuring the layer thickness of the paint, e.g., with a radiation source, a radiation detector, and a conveying path along which the components to be coated are conveyed through the painting and measuring cells. The radiation source may emit light in the visible wavelength range.
