METHOD OF MAKING GEAR WHEEL Russian patent published in 2016 - IPC B23H5/02 B23H7/02 B23H9/00 

FIELD: machine building.

SUBSTANCE: in method first with workpiece spark erosion machining required profile of gear wheel is formed, and after by its electrochemical treatment required surface parameters are provided. Electric erosion treatment is carried out on wire-cutout machine with programmed numerical control, providing as per part drawing production of preset profile of gear wheel with allowance for further processing. During electrochemical treatment of gear wheel is engaged with electrode-tool and checked with voltmeter for absence of short circuit, after which spindle rotation is switched on and repeatedly verified absence of short circuit, then electrolyte is fed to one of electrode surfaces at rate of outflow from nozzle, equal peripheral velocity of mutually rolling electrode surfaces, voltage is supplied to electrodes and gear wheel is processed for time t with rotation first in one direction, after which rotation in opposite direction is switched on and gear wheel is processed for same period of time t.

EFFECT: production of gear wheels with required parameters of precision and surface roughness.
