Description
Изобретение относитс к области машиностроени .The invention relates to the field of engineering.
Известен способ зат жки резьбовых соединений путем предварительной зат жки и удлинени болта, например нагревом.There is a known method for tightening threaded connections by pre-tightening and lengthening the bolt, for example by heating.
Однако известный способ не обеспечивает требуемую точность зат жки вследствие разности удлинений всех болтов соединени .However, the known method does not provide the required tightening accuracy due to the difference in elongations of all the bolts of the joint.
Повышение точности зат жки достигаетс тем, что между гайкой и соедин емой деталью устанавливают временную быстросъемную шайбу, и после удлинени болта, например нагревом , ее замен ют посто нной шайбой, высота которой больше высоты временной шайбы на величину расчетного удлинени болта.Improving the tightening accuracy is achieved by installing a temporary quick-release washer between the nut and the part to be joined, and after the bolt is extended, for example by heating, it is replaced with a permanent washer, the height of which is greater than the height of the temporary washer by the calculated bolt elongation.
На фиг. 1 показано резьбовое соединение в разрезе, после предварительной зат жки; на фиг. 2 - соединение после удлинени болта; на фиг. 3 - соединение после установки посто нной шайбы; на фиг. 4 - соединение после охлаждени . Способ осушествл етс следующим образом.FIG. 1 shows a threaded joint in section, after pre-tightening; in fig. 2 - connection after bolt lengthening; in fig. 3 - connection after installing a constant washer; in fig. 4 - compound after cooling. The method is as follows.
На болт / навинчивают гайку 2, при этом между (нею и соедин емой деталью 3 устанавливают временную быстросъемную шайбу 4. После предварительной зат жки гайки 2 до упора ее в торец шайбы 4 болт удлин ют до получени удлинени А /, которое больше расчетного Д//. Затем временную быстросъемную шайбу 4 замен ют на посто нную шайбу 5, высота которой больше высоты временной Н1айбы на величину расчетного удлинени .The bolt 2 is screwed on the nut 2, while a temporary quick-release washer 4 is installed between it and the connected part 3. After preloading the nut 2 until it stops at the end of the washer 4, the bolt is extended to obtain an elongation A / that is greater than the calculated D / Then, the temporary quick-detachable washer 4 is replaced with a permanent washer 5, the height of which is greater than the height of the temporary I1a by the magnitude of the design elongation.
При охлаждении болта / соединение само 0 зат гиваетс с расчетным удлинениел, пропорциональным удлинению болта.When the bolt is cooled / the joint itself, it tightens with a calculated elongation proportional to the elongation of the bolt.
Предмет изобретени Subject invention
5 Способ зат жки резьбовых соединений путем предварительной зат жки и удлинени болта , например HjjrpeBOM, отличающийс тем, что, с целью повышени точности зат жки, между гайкой и скрепл емой деталью устанавливают временную быстросъемную шайбу и после удлинени болта нагревом ее замен ют на посто нную шайбу, высота которой больше высоты временной шайбы на величину расчетного удлинени болта.5 A method of tightening threaded connections by pre-tightening and lengthening the bolt, for example HjjrpeBOM, characterized in that, in order to improve the accuracy of tightening, a temporary quick-release washer is installed between the nut and the fastened part and after lengthening the bolt by heating it is replaced with a permanent a washer whose height is greater than the height of the temporary washer by the magnitude of the calculated bolt elongation.
