METHOD OF MAKING FLEXIBLE ELEMENTS FOR SEALING ANTIFRICTION BEARINGS Russian patent published in 2001 - IPC

FIELD: production of industrial rubber articles, production of bearings and in other industries. SUBSTANCE: proposed method provides stamping out of flexible elements for antifriction bearings from ring piece blank. To form elements with double-edge symmetrical working profile of hole cross-section blank is compressed axially to 0.3 - 0.8 of its initial thickness and then deformed convex contour on hole is cut off. To form elements with double-edge asymmetrical profile of hole cross-section, blank is first axially bent and then compressed by application of axial force to 0.3-0.8 of its initial thickness, and deformed convex contour is cut off. EFFECT: reduced cost of manufacture of rubberized-metal seals for antifriction bearings. 2 cl, 4 dwg
