Abstract

FIELD: mechanical engineering. SUBSTANCE: threaded profile of a part is formed by the calibrating segment whose width and height is greater than width and height of the threaded profile of the cylindrical rod. The threaded opening is calibrated and major threaded profile is screwed in relatively freely. Sizes of the opening are further decreased due to flexible deformation of a material of which a part to be fastened made. In so doing, the threaded joint is sealed. The screw stops itself due to increased resistance against screwing owing to calibrating part of the profile. EFFECT: improved design. 3 cl, 3 dwg

Изобретение позволяет уменьшить и стабилизировать крутящий момент при ввинчивании, а также обеспечивает самостопорение винта в резьбовом соединении. Резьбовой профиль детали формируется калибрующим участком, имеющим увеличенные размеры по ширине и высоте по сравнению с профилем резьбы цилиндрического стержня. Резьбовое отверстие при этом калибруется и основной резьбовой профиль ввинчивается относительно свободно. В дальнейшем за счет сил упругой деформации материала скрепляемой детали резмеры отверстия уменьшаются. При этом происходит уплотнение резьбового соединения. Винт самостопорится за счет повышенного сопротивления вывинчиванию, которое создает калибрующий участок профиля. 3 ил.The invention allows to reduce and stabilize the torque when screwing in, and also provides self-locking of the screw in the threaded connection. The threaded profile of the part is formed by a calibrating section having increased dimensions in width and height compared to the thread profile of the cylindrical rod. In this case, the threaded hole is calibrated and the main threaded profile is screwed relatively freely. Subsequently, due to the forces of elastic deformation of the material of the fastened part, the hole gauges are reduced. In this case, the threaded joint is sealed. The screw is self-locking due to the increased resistance to unscrewing, which creates a calibrating section of the profile. 3 ill.
