PROCEDURE FOR CONTROL OF EXTREMUM AXIS MISALIGNMENT Russian patent published in 2010 - IPC G01B5/25 

FIELD: machine building.

SUBSTANCE: measuring device made as source of light equipped with rulers crossing at angle of 90° on axle of cone and shaft is fixed on axle of one of shafts by means of cone. A screen is fixed on another shaft; the screen is equipped with an identical measuring device and is additionally equipped with the ruler whereat measuring point begins from the point of rulers crossing at the screen; the ruler is designed to rotate around the point of the benchmark. The source of light is switched on; the additional measuring device is rotated on the screen till matching with projection of the axle of another shaft; distance between crossing points is measured and extremum misalignment is evaluated.

EFFECT: independent from diameters (radii) of shafts measuring and elimination of search of extremum misalignment.
