METHOD OF MANUFACTURING CLOSED METAL RING AND DEVICE FOR REMOVING POLYMERS FROM CLOSED METAL RING

摘要

FIELD: technological processes.;SUBSTANCE: invention relates to the field of manufacturing of the variator belts of vehicles using the technology of preventing nitriding defects. In a drum made of polymers, a closed metal ring is polished, a cleaned ring is rolled, nitrided and the adhered polymers are removed. The device comprises a holding tool, a rotation mechanism, a washing tank with an ultrasonic cleaning fluid, and an ultrasonic wave generator.;EFFECT: elimination of nitriding defects.;8 cl, 15 dwg
