METHOD OF CENTERING MACHINE SHAFTS Russian patent published in 2010 - IPC G01B5/25 

FIELD: mechanics.

SUBSTANCE: invention refers to engineering industry and can be used for centering shafts of the machines containing couplings with long spacing part. Method consists in the fact that offset of shafts relative to each other is measured at their synchronous turn through 180° simultaneously with two indicators out of four ones, which are installed in pairs diametrically opposite on each flange of coupling spacer part in vertical or horizontal planes. Their position is corrected. At that, indicators are installed at equal distance from rotation axis; before shafts are turned, scales of indicators are set to zero. After shafts are turned, one of the machines is turned till readings of diagonally located indicators coincide; after that, one of the machines is moved parallel relative to the position reached during turn till axes of shafts coincide. This position is controlled when readings of all indicators are decreased by two times.

EFFECT: improving accuracy of centering machine shafts and reducing labour input.
