VIBRATION INSTALLATION WITH THREE-DIMENSIONAL MOTION OF WORKING CHAMBER Russian patent published in 2006 - IPC B24B31/73 

FIELD: machine engineering, possibly finishing and strengthening parts with use of granulated medium.

SUBSTANCE: vibration installation includes elastically mounted on base tore-like working chamber with vibrator. Chamber includes sections formed of strips bent to one side along straight lines inclined relative to strip edges and alternatively forming (along strip length) equilateral and isosceles triangles. At two sides of largest equilateral triangle bases of two similar isosceles triangles are arranged. At lateral sides of said similar isosceles triangles two similar equilateral triangles are arranged in such a way that bases of two similar isosceles triangles are abutted to them. In one isosceles triangle equilateral triangle is arranged. Sides of less equilateral triangles differ from sides of large equilateral triangles by the same linear value. Chamber sections are mutually joined along free sides of said triangles.

EFFECT: enlarged manufacturing possibilities, improved efficiency.
