DEVICE FOR REVERSIBLE CIRCULAR MOTION OF WORKING TOOL Russian patent published in 2024 - IPC F16H37/04 F16H19/08 B24B39/04 

FIELD: metal working.

SUBSTANCE: invention relates to metal working and can be used for processing of external surfaces of rotation by finishing-hardening treatment by reverse burnishing. Device comprises a base, a housing, an electric motor, bearing assemblies, a driven shaft with a working tool, tooth gears with full and incomplete teeth and a drive shaft connected by a coupling to the electric motor. On the drive shaft a gear is fixed, having at least two sectors of internal teeth located on the side of the working tool. On the inner side of this gear on the drive shaft there is rigidly fixed a gear with sectors of external teeth, which are located in zones of sectors with no teeth in the gear with internal teeth. Gear with full teeth is fixed on driven shaft with possibility of engagement with sectors of gear with internal teeth. Number of sectors of teeth of each gear and value of angle of each sector depend on value of angle of circular reverse of working tool.

EFFECT: enabling conversion of rotary motion of electric motor into circular reverse motion with preset angle amplitude.
