DEVICE FOR MEASUREMENT OF INTERNAL RIBS HEIGHT Russian patent published in 2008 - IPC G01B5/02 

FIELD: physics, measurement.

SUBSTANCE: invention is related to measuring equipment and is intended for measurement of heights of internal ribs (corrugations) of annular articles. Device for measurement of internal ribs heights consists of assembled casing, on which the following components are installed: measuring indicator with tip, basic supports and clamp with the possibility of displacement. At that casing is equipped with guide lines, in which clamp is installed arranged in the form of wheel installed in slider, basic supports are arranged in the form of generatrices of rotary bodies with the same diameter, have common axis of rotation and are installed in the casing with provision of clearance between ends that is symmetrical to axis of indicator tip. At that axis of indicator tip, axis of basic supports rotation, axis of wheel rotation and axis of guidelines symmetry are installed in one plane, and axes of wheel and basic supports rotation are parallel to each other and perpendicular to indicator tip axis.

EFFECT: provision of possibility of measurement of height and height difference of annular article rib along the whole perimeter.
