Изобретение относитс  к области машиностроени  и может быть использовано в любых резьбовых соединени х, подверженных динамическим нагрузкам и вибраци м.The invention relates to the field of mechanical engineering and can be used in any threaded connections subject to dynamic loads and vibrations.

Известен самоконтр щийс  резьбовой элемент , содержащий стержень с резьбовым пружинным хвостовиком, выполненным в виде цилиндрической пружины с наружной резьбовой поверхностью.A self-locking threaded element is known, comprising a rod with a threaded spring shank made in the form of a cylindrical spring with an outer threaded surface.

С целью увеличени  изгибной жесткости хвостовика дл  повышени  эффективности стопорени  при изменении частоты возмущающих колебаний, действующих на элемент, предлагаемый элемент снабжен дополнительным болтом с резьбовым пружинным концом, ввернутым в продольное резьбовое отверстие, выполненное в стержне элемента со стороны его пружинного хвостовика.In order to increase the flexural rigidity of the shank in order to increase the locking efficiency when the frequency of disturbing vibrations acting on the element is changed, the proposed element is provided with an additional bolt with a threaded spring end screwed into a longitudinal threaded hole made in the element shaft from the side of its spring shank.

На чертеже показан предлагаемый самоконтр щийс  резьбовой элемент в разрезе. The drawing shows the proposed self-locking threaded element in the section.

Элемент состоит из цилиндрического стержн  1 с соосно выполненным в нем резьбовым отверстием, резьбового пружинного хвостовика 2, дополнительного болта 3 с резьбовым пружинным концом 4, ввернутым в продольi;oe резьбовое отверстие стержн  1, и гайки 5.The element consists of a cylindrical rod 1 with a threaded bore coaxially formed therein, a threaded spring shank 2, an additional bolt 3 with a threaded spring end 4 screwed into the longitudinal; oe threaded bore of the rod 1, and a nut 5.

При работе резьбовой пружинный хвостовик 2, будучи предварительно сжатым, представл ет собой демпфер с нелинейной упругой характеристикой , обеспечиваемой предварительным сжатием пружинного хвостовика 2 ст жным болтом также с резьбовым пружинным концом 4, представл ющим собой динамический гаситель колебаний.When operating, the threaded spring shank 2, being previously compressed, is a damper with a non-linear elastic characteristic, provided by the preliminary compression of the spring shank 2 by the clamping bolt also with the threaded spring end 4, which is a dynamic vibration damper.

Комбинаци  нелинейного де.мпфера с динамическим гасителем колебаний значительно улучшает упруго-демпфирующую способность предлагаемого самоконтр щегос  резьбового элемента, повышает эффективность гашени  низкочастотных вибраций и сглаживает пульсации продольных деформаций элемента, повыша  в целом эффективность его са.мостопор щего действи  и надежность в работе.The combination of a nonlinear deamper with a dynamic oscillation damper significantly improves the elastic-damping capacity of the proposed self-locking threaded element, improves the efficiency of damping low-frequency vibrations and smoothes the pulsations of the longitudinal deformations of the element, increasing its overall self-sustaining effect and reliability in operation.
