DEVICE FOR RELAXATION OF RESIDUAL STRESSES AND STABILIZATION OF GEOMETRICAL PARAMETERS OF PARTS OF CYLINDRICAL SHAPES Russian patent published in 2024 - IPC B23P25/00 B24B39/00 

FIELD: machine building.

SUBSTANCE: invention relates to a device for relaxation of residual stresses of cylindrical parts. Device comprises three rolls arranged at angle of 120° between them. Each roller is fixed by means of two carriages and a plate on two rail guides. Plate is fixed by means of screws with a hexagonal head on carriages, each of which is made with possibility of sliding along the rail guide. Each plate is made with possibility of actuation by means of screw pair. Each roller is fixed on a plate in a cage, in which a radial thrust bearing is installed. Mating part of each roll is connected by means of adapter shaft to mating yoke attached by means of spider to yoke of cardan shaft axle. On the opposite end the cardan shaft has a yoke connected by means of a spider with a yoke of a sliding shaft with splines, which is installed in a planetary reduction gear, which is made with possibility of being actuated by a step motor with feedback of the main drive.

EFFECT: as a result, the efficiency of the treatment process is increased.
