Embodiment Construction

[0040] figure 1 A schematic diagram of a robot drive 1 between two axes 2, 3 of a multi-axis robot that can be used, for example, as a painting robot or Used as a handling robot. In this case, the robot transmission 1 enables a rotation of the shaft 3 relative to the shaft 2 about an axis of rotation 4 .

[0041] The axis of rotation 4 is in this case angled at an angle α relative to the vertical line 5 in order to show that different spatial orientations of the robot transmission 1 can be achieved during operation, which for the robot transmission The lubrication of 1 is meaningful, as will be explained in more detail.

[0042] The robot transmission 1 has a transmission housing 6 indicated by dashed lines, which is completely filled with transmission oil during operation. During operation, however, friction-induced heat is generated in the robot transmission 1 , which leads to heating of the transmission oil and to a corresponding expansion of the transmission oil.

Abstract

The invention relates to a robot transmission (1) for a multi-axis robot, in particular for a painting robot or a hand-held robot of a painting system for painting motor vehicle body components. Said transmission comprises a transmission housing (6) which is filled, when in operation, at least partially with a lubricant according to an operationally-dependent lubricant pressure, in order to lubricate the robot transmission (1), and has a construction-defined maximum pressure for the lubrication pressure. The transmission housing (6) is not air-tight if the lubrication pressure in the transmission housing (6) exceeds the maximum pressure. According to the invention, the robot transmission also comprises a pressure compensation device (7) which compensates the pressure in the transmission housing (6) and thus prevents the lubrication pressure in the transmission housing (6) from exceeding the maximum pressure.

Description

technical field [0001] The invention relates to a robot drive for a multi-axis robot, in particular a painting robot or a handling robot of a painting plant for painting body parts of motor vehicles. Background technique [0002] In modern painting installations for painting motor vehicle body components, multi-axis robots are used, on the one hand as a painting robot for the paint application and on the other hand as a handling robot for handling the components to be painted (e.g. hood openers, door openers). Such a robot has a plurality of robot transmissions for moving the individual robot axes, which are usually lubricated with oil. For this purpose, the transmission housing of the corresponding robot transmission is partially filled with oil. [0003] In this case, on the one hand, the oil level in the transmission housing must be so high that all components to be lubricated lie below this oil level and are therefore sufficiently lubricated. [0004] On the other han...
