METHOD FOR IMPULSE-PERCUSSION FINISHING OF CYLINDRICAL GEAR WHEELS WITH CIRCULAR TEETH Russian patent published in 2004 - IPC

FIELD: plastic metal working, strengthening gear wheels. SUBSTANCE: method comprises steps of working different recesses of circular teeth by means of impulse-percussion tool mounted on tool spindle with possibility of rotation around its own axis and having body with central axial opening and deforming members arranged along annular line with diameter equal to nominal diameter of circular teeth of worked gear wheel. In order to enlarge manufacturing possibilities, axis of impulse-percussion tool is arranged normally relative to rotation axis of worked tool. Tool has retainer which is provided with deforming members, rolling bodies arranged between deforming members, elastic members arranged on deforming members and designed for returning them to initial position after percussion; disc arranged in tool body and having peripheral ducts-nozzles inclined by 45 degrees relative to surface of central axial opening of tool body; ring secured to end of retainer and designed for preventing falling out of deforming members. EFFECT: enhanced efficiency of working. 7 dwg, 1 ex
