Abstract:
The invention relates to an apparatus (1) and a method for the condition-dependent maintenance of hydrostatic displacement units (2), in particular axial piston machines (3) operated as pumps or motors. Mounted on the hydrostatic displacement unit (2) are acceleration sensors (4) and/or contamination level sensors (5) which capture vibration data and/or contamination data of the hydrostatic displacement unit (2) and are connected to an evaluation unit (6) which temporarily stores the vibration data and/or contamination data. A communication unit (7) connected to the evaluation unit (6) retransmits said data.
