METHOD FOR LAPPING WORKING PROFILE OF GEAR WHEELS AND APPARATUS FOR PERFORMING THE SAME Russian patent published in 2004 - IPC

FIELD: machine engineering, restoration and improving quality of gear wheels.

SUBSTANCE: method is realized in medium of low electrically conducting liquid at working position of gearing and at supplying electric current from source through electric current leads arranged on lapped gear wheels. In order to enhance quality of engagement of gear wheels, preliminarily resistance pickup is adjusted according to designed contact pressure between teeth. The electric current is turned-on and gear wheels are driven to rotation; load value is controlled due to applying electric current to braking or acceleration winding of rotor of loading device in proportion to error signal value between designed and measured values of contact pressure. Apparatus for performing the method includes engaged gear wheels, one wheel is connected with loading device. In order to achieve the same result, loading device is arranged on driven gear wheel with possibility of operating in acceleration or braking mode and through converter and resistance pickup adjusted for designed contact pressure between teeth of gear wheels it is connected with driving gear wheel.

EFFECT: enhanced quality of engagement of gear wheels.
