Description

Известны самостонор щиес  гайки, верхн   коническа  часть которых (хвостовик) снабжена прорез ми и после нарезки резьба несколько деформировапа - сжата в радиальном направлении. При навинчивании гайки, на болт согнутые элементы ее конической части выпр мл ютс , что способствует увеличению возникающих на поверхност х контакта резьбы сил трени . Это исключает самоотвинчивание .The self-locking nuts are known, the upper conic part of which (the shank) is provided with slots and, after cutting, the thread is somewhat deformed, compressed in the radial direction. When the nut is screwed on, the bent elements of its conical part are straightened onto the bolt, which contributes to an increase in the frictional forces arising on the contact surfaces of the thread. This excludes self-unscrewing.

Описываема  гайка отличаетс  от известных тем, что хвостовик ее выполнен в виде кольца с тонкостенной перемычкой и отверстием , диаметр которого обеспечивает прессовую посадку гайки на шейку сопр гаемой детали.The described nut differs from the known ones in that its shank is made in the form of a ring with a thin-walled bridge and a hole, the diameter of which provides a press fit of the nut on the neck of the matching part.

Такое выполнение гайки повышает надежность резьбовых соединений, так как независимо от усилий зат жки резьбового соединени  создаютс  два момента сопротивлени : момент от нат га вследствие прессовой посадки кольца на шейку сопр гаемой детали и момент трени  в витках резьбы вследствие поджати  витков гайки к виткам винта.Such an embodiment of the nut improves the reliability of the threaded connections, because regardless of the tightening torque of the threaded connection, two moments of resistance are created: the torque from tension due to the press fit of the ring on the neck of the mating part and the moment of friction in the thread windings due to tightening the nut turns to the screw turns.

На фиг. i изображена гайка, навинченна  на ось подшипникового узла; на фиг. 2 - гайка в разрезе; на фиг. 3 - то же, в плане.FIG. i shows a nut screwed onto the axis of the bearing assembly; in fig. 2 - nut in the section; in fig. 3 - the same in terms of.

Самостопор ща с  гайка / Быполиеиа за одно целое с кольцом 2 и тонкостенной иеремычкой 3, которые составл ют .хвостовик гайки . Последний может быть снабжен прорез ми 4.Self-locking nut / Bypolieia in one piece with ring 2 and thin-walled iremik 3, which constitute the shank of the nut. The latter can be provided with slots 4.

При навинчипании на ось 5 подшипникового узла гайка своим кольцом 2 будет с нат гом сопр гатьс  с шейкой 6, способству  еще большему увеличению возннкаюпиьх иа поверхност х контакта резьбы сил трени , что исключает самоотвинчиванне.When screwing onto the axis 5 of the bearing assembly, the nut with its ring 2 will fit tightly with the neck 6, contributing to an even greater increase in the emergence of contact surfaces of the thread of the friction forces, which eliminates self-loosening.
