A method for early damage recognition of a machine, and program and control unit for executing the method are disclosed. The method is disclosed for early damage recognition, wherein a frequency-transformed signal, filtered of dominant excitations, is supplied to a comparative early damage recognition, and wherein, after the filtering, damage of the machine is recognized by comparing the signal to a comparison value.

Method for early damage recognition, and program and control unit for executing the method

A hydrostatic machine includes a housing and a drive shaft. The housing has an inner housing part, configured to receive a force flow, an outer housing part, configured to seal and damp, and a housing floor. The drive shaft is configured, on an input side, to pass coaxially through the housing floor and is configured, on an output side, to pass coaxially through a swash plate. The drive shaft is connected to a cylinder drum in a rotationally fixed manner. The hydrostatic machine is configured in a weight-saving manner and is configured such that propagation of vibrations in the hydrostatic machine, and noise generation therefrom, are reduced. To this end, the drive shaft is further configured to pass only partially through the inner housing part and is rotatably mounted in the housing floor and the inner housing part.
