METHOD OF JOINING SHAFT WITH BUSHING WITH INTERFERENCE Russian patent published in 1997 - IPC

FIELD: mechanical engineering. SUBSTANCE: parts of different hardness are used for the joining. By means of plastic deforming elliptic hollows as well as projections, whose height varies over the periphery, are made on the mated surface of higher hardness. Rolling bodies set in the cage and movable member whose side interacts with them are used as a tool for the plastic deforming. The plastic deforming is carried out by radial movement of the rolling bodies due to axial movement of the movable member which acts on them. The movable member can be set in ultrasonic vibration the direction of which is the same as that of the movement. EFFECT: simplified method. 3 cl, 6 dwg
