Abstract (en)
[origin: WO2007068448A1] The invention relates to a device (1) for monitoring the state of hydrostatic displacement units (2), in particular, axial piston machines (3) which are actuated as a pump or a motor. Said device comprises (1) a detector unit (4) comprising a plurality of sensors (5) which are arranged on the hydrostatic displacement unit (2) for detecting monitoring data (6) and operational data (7), in addition to an evaluation unit (8) which comprises a device (9) for analysing the monitoring data in the frequency range and a device (10) for analysing the monitoring data in a period of time. A diagnosis unit (11), which comprises an output unit (13), is connected to the evaluation unit (8).
