METHOD OF CONNECTION OF SLEEVE-BUSHING-TYPE PARTS WITH INTERFERENCE Russian patent published in 2021 - IPC B23P11/02 B23P19/27 

FIELD: machine building.

SUBSTANCE: invention relates to machine building and can be used in mechanical assembly production for connection with sleeve-type parts interference. Proposed method comprises press-fitting of shaft-bushing parts and shaft displacement relative to bush in direction opposite to direction of shaft motion at pressing-in until shaft-bushing is detached. At that, press is used, comprising main cylinder and auxiliary cylinder located relative to pressed shaft, at that, the shaft pressing into the bushing is performed by the master cylinder punch, and shaft displacement relative to bushing is performed by male die of auxiliary cylinder by means of creation of hydraulic impact in piston cavity of auxiliary cylinder and in rod cavity of master cylinder.

EFFECT: technical result of invention is expansion of technological capabilities of method, which is provided with possibility of obtaining detachments, including multiple ones, without reinstallation of assembled parts, and increased strength of assembled connection of parts with interference due to increased area of contact surfaces of parts of assembled connection.
