METHOD TO PROVIDE THREADED JOINT WITH POSSIBILITY OF ADJUSTMENT OF CONTACT FORCE ON THREAD TURNS Russian patent published in 2005 - IPC

FIELD: mechanical engineering.

SUBSTANCE: proposed method comes to the following: blank of nut is clamped between two coupling members and is fixed in position by threaded member, thanks to which self-balancing tensile forces appear in nut. Rod is driven into space of bolt blank, is stretched and fixed by other threaded member, thanks to which self-balancing compressing forces appear in bolt blank. Then thread is cut in blanks of bolt and nut, and bolt is connected with nut. Using said threaded members and adjusting extension and compression forces, contact forces on thread turns are adjusted.

EFFECT: possibility of adjusting contact forces irrespective of conditions of loading.
