METHOD OF MEASURING CLEARANCES Russian patent published in 1999 - IPC

FIELD: measuring clearances between movable and fixed parts of articles. SUBSTANCE: cocking of movable part relative to fixed one is created by successive application of force to movable part in two opposite directions. Every time when cocking is created, axial misalignment and position of movable part relative to fixed one are measured. Then movable part is shifted relative to fixed one from one extreme position to the other and length of movable part is checked on opposite sides in plane of its contact with fixed part. EFFECT: enhanced accuracy of measurement of clearances due to taking into account curvature of movable part. 5 dwg
