Изобретение относитс  к области общего машиностроени .This invention relates to the field of general engineering.

Известен способ сборки резьбовых соеди нений при помощи винта и гайки, выполненной из термопластичного материала путем формообразовани  резьбы гайки при навинчивании ее Н:а стержень бОЛта.The known method of assembling threaded connections with the help of a screw and a nut made of a thermoplastic material by forming a nut thread when screwing it H: a bolt of the bolt.

Однако этот способ не позвол ет получить надежное предварительное напр жение резьбовых соединений вследствие возможного срыва наиболее натруженных витков при завинчивании пластмассовой детали, например гайки.However, this method does not allow to obtain a reliable prestressing of the threaded connections due to the possible breakdown of the most strained turns when screwing a plastic part, for example a nut.

ПредлагавМый способ отлинаетс  ют известного тем, 4TOi соедин емые детали предварительно сжимают, а, после формообразовани  резьбы и запг жки гайку и болт охлаждают и снимают предварительную нагрузку.The proposed method is known to those, 4TOi, the parts to be joined are pre-compressed, and, after the thread has been formed and loaded, the nut and bolt are cooled and the preload is removed.

Это создает предварительное напр жение В.ИТКОВ резьбы.This creates a prestressing of the V.ITKV thread.

Предлагаемый способ пог сн етс  чертежом .The proposed method is illustrated in a drawing.

В детали, подлежащие соединению, например две дерев нные панели, вставл ют металлилеский винт (болт) /, головка которого  вл етс  одной из опорных поверхностей. На детали 2 через шайбу 3 передаетс  давление , вызывающее упругую деформацию EQ сжати . Затем производитс  формование второй резьбовой детали - гайки 4. После совместного охлаждени  гайки и болта, внешние сж:има.юшие усили  снимаютс .In parts to be joined, for example, two wood panels, a metal screw (bolt) / is inserted, the head of which is one of the supporting surfaces. At part 2, pressure is transmitted through washer 3, causing elastic deformation of the EQ compression. Then, a second threaded part is formed — the nuts 4. After the nuts and bolt are cooled together, the external screws: IM are removed. The remaining forces are removed.

Под действием внутренних напр жений соедин бмые детали получают деформацию EI,Under the action of internal stresses, the joint parts receive an EI deformation,

котора  и определ ет предварительное напр жение в резьбовом соединении.which determines the prestress in the threaded connection.

Предмет изобретени Subject invention

Способ сборки резьбовых соединений при помощи винта и гайки, выполненной из термопластичного материала, путем формообразовани  резьбы гайки при навинчивании ее на стержень болта., отличающийс  тем, что,The method of assembling threaded joints with the help of a screw and a nut made of a thermoplastic material by forming a nut thread when screwing it onto a bolt rod. Characterized in that

с целью создани  предварительного напр жени  витков резьбы, соедин емые детали предварительно сжимают, а после формообразовани  резьбы и зат жки, гайку и болт охлаждают и снимают предварительную нагрузку .in order to create a prestressing of the threads, the parts to be joined are pre-compressed, and after forming the thread and tightening, the nut and bolt are cooled and relieved.
