Abstract

Изобретение относитс к машиностроению и может быть использовано дл стопорени гаек на крепежных детал х преимущественно с тарированной зат жкой. Цель изобретени - повышение надежности. На резьбовом стержне (С) 1 выполнен диаметральный торцовый паз (П) 2. Гайка 3 снабжена диаметральными отверсти ми 4 и установлена на С 1. В П 2 размещен цилиндр 5 с отверстием 6, выполненным под углом к его оси. В совмещенных отверсти х 6 и 4 установлен шплинт (Ш) 7. Диаметр цилиндра 5 равен ширине П 2, котора больше диаметра отверстий 4. Благодар увеличенной ширине П 2 при вращении цилиндра 5 вокруг его оси обеспечиваетс совмещение отверстий 6 и 4, чем достигаетс возможность стопорени гайки 3 на С 1 Ш 7 без ее доворачивани , так как Ш 7 устанавливаетс и фиксируетс сразу после тарированной зат жки соединени , что приводит к снижению монтажных напр жений в соединении и повышает его надежность. 1 з.п. ф-лы, 3 ил.The invention relates to mechanical engineering and can be used to lock the nuts on fasteners mainly with calibrated fasteners. The purpose of the invention is to increase reliability. A threaded rod (C) 1 has a diametrical end groove (P) 2. A nut 3 is provided with diametral holes 4 and mounted on C 1. A second cylinder 2 with a hole 6 placed at an angle to its axis is placed. A pin (W) 7 is installed in the aligned holes 6 and 4. The diameter of the cylinder 5 is equal to the width P 2, which is larger than the diameter of the holes 4. Thanks to the increased width P 2, when the cylinder 5 rotates around its axis, it is possible to align the holes 6 and 4. stopping the nut 3 on the C 1 W 7 without turning it again, since W 7 is installed and fixed immediately after the calibrated tightening of the joint, which leads to a decrease in the installation stresses in the joint and increases its reliability. 1 hp f-ly, 3 ill.
