Apparatus and method for the condition-dependent maintenance of hydrostatic displacement units
First Claim
1. An apparatus for the condition-dependent maintenance of hydrostatic displacement units of axial piston machines operated as pumps or motors, said apparatus comprising:
- at least one first acceleration sensor and at least one contamination level sensor which capture vibration data and contamination data of a hydrostatic displacement unit and which are connected to an evaluation unit which evaluates the vibration data and the contamination data, said at least one contamination level sensor being mounted on the hydrostatic displacement unit, wherein said at least one first acceleration sensor is provided on a pump or motor housing surface in a bearing region of the hydrostatic displacement unit for detection of shaking or vibrations deleterious to the hydrostatic displacement unit,a communication unit, which is connected to the evaluation unit and retransmits said data for further processing, said retransmission being effected via an intranet or Internet connection, the communication unit being integrated in an onboard electronic unit of the hydrostatic displacement unit, anda Web server being installed in the communication unit.

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.
