INTERFERENCE JOINT Russian patent published in 1998 - IPC

FIELD: mechanical engineering; connection of male and female parts; interference fitting along cylindrical and conical surfaces. SUBSTANCE: part featuring higher in joint is provided with grooves with curvilinear shape and variable depth in length. Assembling is carried out with heating of female part with subsequent cooling to level temperatures in joint. Owing to change in resilient stressed condition of mated surfaces, load bearing capacity is increased and corrosion and mechanical wear of interference joints are decreased. EFFECT: improved reliability of joint. 6 cl, 5 dwg
