THREADED ELEMENT AND A CONNECTION CREATED ON ITS BASIS Russian patent published in 2021 - IPC F16B39/282 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to threaded elements. The threaded element (1) contains an annular section (8) for bearing on the supporting section (17) of the counterpart of the threaded connection or a structural element separate from it. Anchoring means (9) are formed on the annular portion (8) for positive locking in this support portion (17) to create a positive locking connection, which are somewhat spaced apart from each other in the circumferential direction (F) of tightening. Anchoring means (9) uniformly distributed in the circumferential direction of the forming sections (10), each of which has a lower forming edge (11) extending in the direction (T) of axial movement. In the circumferential direction (F) of tightening, in front of these forming sections (10), there is one recess (12) for receiving the material deformable by said corresponding forming section (10) of the support section (18). Each of these recesses (12) on the opposite to the corresponding forming section (10) in the circumferential direction (F) of the tightening of the circumferential side is bounded by a wall, which has a ramp-like rising against the circumferential direction (F) of tightening upwards opposite to the direction (T) of axial movement the first wall section (13) or consists of it, and each of these recesses (12) on the circumferential side opposite to the ramp-shaped first wall section (13) against the circumferential direction (F) of tightening, is limited to adjacent to the forming edge (11 ) and / or to the first wall section (13) by the second wall section (14) of the corresponding forming section (10). Each of the first wall sections (13), opposite to the forming sections (10) in the circumferential direction (F) of tightening and made each as a rectilinear ramp, has an angle (δ) of rise relative to the radial plane (R), which is crossed perpendicularly by the specified longitudinal middle axis ( L), this angle (δ) of ascent by an angle between at least 0.5 ° and a maximum of 20 °, in particular between at least 1° and a maximum of 15 °, preferably between at least 1.5 ° and a maximum of 10 °, even more preferably between at least 2 ° and a maximum of 8 °, most preferably at least 2 ° and a maximum of 5 ° greater than the lead angle of the thread helix (5), and the second wall portions (14) are rounded or made like rounding. The connection contains a threaded element (1) and a counterpart of the threaded connection. The thread (5) of the threaded element (1) is screwed with the mating thread of this mating element of the threaded connection, and the material of the support section (17) of the mating element of the threaded connection or axially clamped between the mating element of the threaded connection and the threaded element (1) is molded into the recesses (12) structural element to create a form-fit connection. The deformed material with material closure is connected to the non-deformed material of the support section (17).

EFFECT: high holding or braking torque.
