Abstract
СПОСОБ ЗАТЯЖКИ РЕЗЬБОВЫХ СОЕДИНЕНИЙ, заключающийс в том, что устанавливают на предварительнЬ пропущенный через соедин емые детали болт упругую шайбу, завинчивают гайку до контакта с шайбой и деформируют последнюю до заданного конечного усили в болте , отличающийс тем, что, с целью снижени трудоемкости и повышени точности зат жки, используют упругую шайбу из биметалла, предварительно нагревают ее и деформируют ее за счет охлаждени . 9 СО Од ю ;оA METHOD FOR TIGHTENING THREADED CONNECTIONS, which consists in installing an elastic washer that was passed through the parts being joined, tighten the nut to contact with the washer and deform the latter to a predetermined final force in the bolt, which is different in order to reduce labor intensity and increase puffs, use a bimetal spring washer, preheat it and deform it by cooling. 9 SO One; o
Description
Изобретение относитс к сборке машин и механизмов и может быть использовано при зат жке резьбовых соединений.The invention relates to the assembly of machines and mechanisms and can be used when tightening threaded connections.
Цель изобретени - снижение трудоемкости и повышение точности зат жки за счет управлени температурой нагрева упругой шайбы из биметалла.The purpose of the invention is to reduce the labor intensity and increase the accuracy of the tightening by controlling the heating temperature of the elastic bimetal washer.
На фиг. 1 изображено резьбовое соединение перед зат жкой; на фиг. 2 - то же, после зат жки.FIG. 1 shows a threaded connection before tightening; in fig. 2 - the same after tightening.
Способ зат жки резьбовых соединений осуш,ествл етс следующим образом.The method of tightening the threaded connections is dried as follows.
Через соедин емые детали 1 и 2 пропускают болт 3. На болт 3 устанавливают предварительно нагретую до определенной температуры упругую шайбу 4 из биметалла.A bolt 3 is passed through the connected parts 1 and 2. An elastic washer 4 made of bimetal is preheated to a certain temperature and is installed on the bolt 3.
Нагрета биметаллическа шайба 4 приобретает бочкообразную форму. После установки шайбы 4 на болт 3 навинчивают гайку 5 до плотного контакта с шайбой 4, которую затем охлаждают. В процессе охлаждени биметаллическа шайба 4 выпр мл етс и создает заданное усилие в болте 3. Процесс зат жки резьбового соединени закончен. Изменением температуры предварительного нагрева шайбы 4 можно регулировать величину усили зат жки.Heated bimetallic washer 4 becomes barrel-shaped. After installing the washer 4 on the bolt 3 screw the nut 5 to close contact with the washer 4, which is then cooled. During the cooling process, the bimetallic washer 4 is straightened and creates a predetermined force in the bolt 3. The tightening process of the threaded joint is completed. By varying the preheat temperature of the washer 4, it is possible to adjust the amount of pulling force.
