DETERMINATION OF ENDLESS CYLINDRICAL SURFACE CURVATURE RADII Russian patent published in 2015 - IPC E01B35/06 G01B21/10 G01B21/20 

FIELD: transport.

SUBSTANCE: invention relates to determination of endless surface curvature radius, for example, that of the track rail working surface. Wheel rolling path width is defined as well as the segment height measured from the chord subtending the circle arc of the rolling path surface outline. Quotient of the division of the sum of squares of the wheel rolling path half width and said segment height is calculated by said double height of the segment. Said segment height is measured in the axis extending from the rolling path centre perpendicular the chord subtending the extreme points of the rolling part surface.

EFFECT: possibility of determination under open pit conditions without complicated calculations and shaping the worn-out rails in due time.
