FIELD: process engineering. ^ SUBSTANCE: invention relates to machine building, particularly, to jointing of parts by inserting internal part 1 into external part 2. The latter has lengthwise channels 3, 4 to divide said part 2 into load bearing part 2.1 and sleeve part 2.2 to be jointed together to form closed cavity. Rods 5 are fitted into channels 3, 4. Permanent joint is produced on end faces of said rods by welding to seal said closed cavity. External part 2 is placed on internal part 1 to fill said closed cavity with working body at pressure required to transmit load by friction forces on joint surface between said parts 1 and 2. ^ EFFECT: higher durability, possibility of multiple assembly/disassembly. ^ 3 cl, 5 dwg |
