INTERFERENCE JOINT Russian patent published in 2025 - IPC F16B4/00 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to machine building and can be used to ensure tightness when assembling parts connected with interference from different materials. Assembly is carried out under the action of a press. Interference connection of female and male parts is carried out under the action of a press, wherein on the male part there are two groups of 3-4 semi-circular annular projections located at a distance l1=1/3-1/5 from the ends of the connection, and the height of the projections h is equal to maximum tightness plus 10-50%. Distance between the projections b and the width of the projections a are equal to two times the height of projection 2h.

EFFECT: provision of tightness of connection with interference, assembled under action of press.
