English to Polish Tech/Engineering Engineering (general)

The invention relates to a threaded connection with a self-locking threading.

In self-locking threadings of that type of connection, the threads (also termed teeth) of the male end and the threads (also termed teeth) of the female end have a constant lead but variable thread widths. More precisely, the widths of the crests of the threads (or teeth) increase progressively for the threads of the male end or female end respectively with increasing distance from the male end or female end.

Locking occurs for self-locking threadings when the flanks of the male threads (or teeth) lock against the flanks of the corresponding female threads (or teeth).

In order to overcome those problems, one solution consisting in producing a threading in which the width of the threads (or teeth) of the end of the male threaded zone is larger has been considered and this without changing the total length of the threaded zones.
