METHOD FOR ABRASIVE-DIAMOND INTERMITTENT ELECTRIC-CONTACT WORKING OF GEAR WHEELS WITH CIRCULAR TOOTH Russian patent published in 2004 - IPC

FIELD: working of gear wheels, gear grinding. SUBSTANCE: method comprises steps of working by means of abrasive-diamond tool at rolling around during forward and backward strokes different recesses of teeth while using abrasive-diamond intermittent cup-shaped cylindrical tool having two generating surfaces for simultaneously profiling convex and concave faces of teeth. Such tool has dents and indentations and it is mounted on tool spindle whose axis is normal relative to rolling around direction. Indentations of tool are filled with impregnator being copper- graphite alloy. Electric current is supplied to worked part and to tool due to contact of tool dent and part; when indentation of tool enters contact zone of tool and part, electric current is cut off. EFFECT: enhanced efficiency of working. 3 dwg, 1 ex
