Изобретение относитс к машиноетроению и может быть использовано в резьбовых соединени х, подверженных действию вибраций и знакопеременных нагрузок.The invention relates to machine-winding and can be used in threaded connections exposed to vibrations and alternating loads.
Известен самоконтр щийс резьбовой элемент, содержащий резьбовой пружинный хвостовик и гайку ЦjKnown self-locking threaded element containing a threaded spring shank and nut Cj
Недостатком указанного элемента вл етс низка надежность стопорени . Гайка удерживаетс на хвостовике только засчет сил трени ,поэтому в услови х действи значительны по величине вибраций и знакопеременных нагрузок существует возможность ее самоотвинчивани .The disadvantage of this element is low locking reliability. The nut is held on the shank only due to the forces of friction, therefore, under the conditions of action of considerable magnitude of vibrations and alternating loads, there is the possibility of its unscrewing.
Наиболее близким к предлагаемому по технической сущности и достигаемому результату вл етс самоконтр щийс резьбовой элемент, содержащий резьбовой пружинный хвостовик, гайку и дополнительный болт с головкой , установленный в осевом отверстии резьбового хвостовика 2.Closest to the proposed technical essence and the achieved result is a self-tightening threaded element containing a threaded spring shank, a nut and an additional bolt with a head mounted in the axial bore of the threaded shank 2.
Недостатком данного устройства вл етс низка надежность стопорени в услови х действи вибраций и знакопеременных нагрузок.Повысить надежность стопорени можно увеличением усили зат жки соединени .The disadvantage of this device is the low reliability of the locking under the conditions of vibration and alternating loads. To increase the reliability of the locking can be increased by increasing the tightening torque of the connection.
но оно ограничено прочностью соедин емых деталей и самого-пружинного хвостовика. Кроме того, при зат жке соединени возникает значительный скручивающий момент, действующий на пружинный хвостовик. Поэтому после зат жки соединени на гайку действует вращающий Момент, стрем щийс повернуть гайку в направлении, протиo воположном направлению ее закручивани . Это может привести к самоотвинчиванию гайки.but it is limited by the strength of the parts being joined and the self-spring shank. In addition, when the joint is tightened, a significant twisting moment occurs on the spring shank. Therefore, after tightening the joint, a rotating torque acts on the nut, which tends to turn the nut in the direction opposite to the direction of its tightening. This may cause the nut to loosen.
Цель изобретени - повышение надежности стопорени .The purpose of the invention is to improve the reliability of the lock.
