FACILITY FOR ROTOR STRENGTHENING OF SCREW AND COMPLEX CONTOURED SURFACE Russian patent published in 2009 - IPC B24B39/04 

FIELD: metallurgy.

SUBSTANCE: invention relates to metal deformation process. Particularly it relates treatment of impulse - impact surface plastic deformation. Facility contains body, allowing individual control and implemented in the form of cover ring blank with link rail on its inner surface, on which there are located deformation elements, link and compression spring, providing pressure to link. Ring is installed in link with ability of providing the additional oscillatory motion relative to blank longitudinal axis. Link is pivotally suspended on hollow bearing assembly sleeve, the letter is located on the one end of carrier, and on the other end of carrier it is installed mentioned individual control with the ability of rotary motion translation to the ring with deformation elements.

EFFECT: as a result there are manufacturing capability expanding, it is provided control ability of strengthened layer depth, degree of strengthening and surface microrelief.
