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.
