PLANT FOR SURFACING INNER CYLINDRICAL SURFACES OF PARTS BY CENTRIFUGAL CASTING Russian patent published in 2000 - IPC

FIELD: restoration of worn inner cylindrical surfaces of parts. SUBSTANCE: proposed plant includes rotatable ingot mold, mechanism for centering the part relative to ingot mold, mechanism for feeding part to ingot mold and locking it there and device for heating the part which is just inductor mounted on rod by means of bracket which is rigidly connected with shaft. Movable and fixed rings are secured on shaft which is mounted for longitudinal motion in load-bearing bushes. Distance through which inductor is inserted into part is regulated by means of movable locking ring. EFFECT: facilitated mounting of units and readjustment in case of change of sizes of parts to be reconditioned; improved quality of parts treated due to reduction of heating of surfaces which are not treated. 4 dwg
