GEAR TESTING ROLLER GUIDE Russian patent published in 1997 - IPC

FIELD: metallurgy, continuous casting of steel. SUBSTANCE: gear testing roller guide is manufactured in the form of measurement section moved along roller guide and composed of spring-loaded guides for two pairs of rollers placed in opposition and having limiter of their longitudinal relative displacement and sensor of mutual position of guides. Novelty of invention lies in its provision with one more sensor of mutual position of guides that is mounted between them with displacement relative to first sensor along guide. In this case mutually mobile parts of both sensors are fixed rigid on guides. Thus guides and sensors in assemblage form aid ensuring continuous measurement of spread of rollers over considerable parts of their circumferences. Given measurements may serve to detect lack of roundness of surface of roller and eccentricity of axes of oscillation and symmetry of rollers which enhances accuracy of adjustment of zone of secondary cooling of MNLZ. EFFECT: continuous measurement of spread of roller guide of MNLZ over considerable part of circumference of roller. 5 dwg
