Abstract
A connection element (1) has a thread (2) that can be made to engage with a mating thread such as, for instance, a nut. The thread includes locking means (3) that acts upon the mating thread. The locking means (3) are formed by flanks (4, 5; 6, 7, 8, 9) of at least one section (10; 11) of the thread (2) whose arrangement with respect to each other is changed vis-à-vis the arrangement of the flanks (18, 19) of the thread (2) outside of the locking section (10; 11) in such a way that, when the thread (2) engages with the mating thread, a locking force is generated on at least one of the flanks (4, 5; 6, 7, 8, 9) of the locking section (10; 11).
Claims15
A connection element (1) having a thread (2) adapted to engage with a mating thread, comprising:
- a locking means (3) to generate a locking force that acts upon the mating thread, wherein said locking means (3) is formed by at least a first flank (6) of at least one locking section (11) of the thread (2), and a second flank (9) of the at least one locking section (11) of the thread (2), with each flank having a radially stepped raised flank face that is offset from an adjacent thread face of the thread of the locking section along one winding of the thread (2) and is substantially parallel to the adjacent thread face of the thread of the locking section, and with the first flank offset from the second flank in axially opposite directions and distributed alternatingly with respect to one another along the one winding of the thread (2) so that when the thread (2) engages with the mating thread, the locking force is generated on at least one of the flanks (6, 9) of the locking section (11), and wherein two or more locking sections (11) are distributed along the one winding.
A method for lockably joining a connection element to a mating thread, comprising:
- joining by screw connection a connection element (1) having a thread (2) to a mating thread, wherein the connection element comprises at least a first flank (6) of at least one locking section (11) of the thread (2), and a second flank (9) of the at least one locking section (11) of the thread (2), with each flank having a radially stepped raised flank face that is offset from an adjacent thread face of the thread of the locking section along one winding of the thread (2) and is substantially parallel to the adjacent thread face of the thread of the locking section, and with the first flank offset from the second flank in axially opposite directions, and distributed alternatingly with respect to one another along the one winding of the thread (2), and wherein two or more locking sections (11) are distributed along the one winding.
A threaded connection element with at least one locking section, comprising:
- a thread with multiple windings, with the thread defining a thread tip of a uniform radial height along its axial length;
- at least a first flank of the at least one locking section of the thread;
- and
- at least a second flank of the at least one locking section of the thread, with each flank having a radially stepped raised flank face that is offset from an adjacent thread face of the thread of the locking section along one winding of the thread and is substantially parallel to the adjacent thread face of the thread of the locking section, and with the first flank offset from the second flank in axially opposite directions so that when the thread engages with a mating thread, the locking force is generated on at least one of the flanks of the locking section.
