APPARATUS FOR CIRCULAR OSCILLATION OF A WORKING TOOL Russian patent published in 2022 - IPC B24B39/04 

FIELD: shaping.

SUBSTANCE: invention relates to an apparatus for processing outer surfaces of rotation by finishing and hardening processing by surface plastic deformation and is intended for use in various branches of the metal working industry. The apparatus comprises a body, an electric engine, disks, bearing assemblies, a drive shaft, and a driven shaft connected with the working tool. In order to create circular oscillation on the output shaft, the apparatus comprises two disks of different diameters interconnected by a rod. The disk of a smaller diameter is secured on the drive shaft, configured for constant rotational movement. The disk of a larger size is secured on the driven shaft and receives the oscillating motion transmitted to the working tool. The rotational motion of the electric engine is converted into a circular oscillating motion with a predetermined amplitude.

EFFECT: reliability of operation is increased, dimensions of the apparatus are reduced with the maintained quality of processing.
