FIELD: machine building.
SUBSTANCE: there are measured spectres of envelope of vibration signal at two modes of machine operation: at travel of a machine drive in whole working range and at alternate travel of the machine drive in values corresponding to possible backlashes in the drive. Further, there are determined average values of peak factors at two modes of machine operation at frequencies corresponding to frequency of rolling bodies and multiple to frequency of rolling bodies. Actual backlash in machine drive is determined by comparing above said average values of peak factors at two modes of machine operation.
EFFECT: measuring backlashes in drives at full travels during machine operation.
