METHOD FOR JOINING PARTS WITH INTERFERENCE Russian patent published in 2000 - IPC

FIELD: machine engineering, namely joining parts such as shaft-sleeve with interference. SUBSTANCE: method comprises steps of making on joined surface of male part recesses and forming annular protrusions along perimeters of recesses by plastic deformation at using tool including retainer with rolling bodies and movable member with bearing surface concentric relative to joined surface of male part; imparting rotation to retainer and imparting radial motion to movable member; at making recesses limiting their depth by means of annular stop with end face; providing contact of said end face (at termination of deforming process) with surface of male part; forming gap between joined parts, connecting them one to another and taking up gap. EFFECT: increased loading capability of joined unit. 4 dwg
