Kuvandudza Thread Engagement Kuderedza Fastener Kukundikana muKuvaka Zvikumbiro

Mukuvaka kwemaitiro, kutadza kwefastener hakuwanzo kukonzerwa nekusimba kwezvinhu chete. Muzviitiko zvakawanda, kusakwana kana kusakodzera kubatanidzwa kweshinda ndicho chinhu chakavanzika seri kusunungura majoini, kudhonza bhaudhi-kunze, uye kutadza kubatanidza nguva isati yakwana.

Kunzwisisa mabatiro anoita shinda yekutakura zvinhu-uye kuti ingadzorwe sei kuburikidza nemaitiro uye nekutenga zvinhu-zvakakosha pamapurojekiti ekuvaka akachengeteka uye akavimbika.

 

 

 

Thread engagement urefu inotaridza kuti tensile uye shear mitoro inogovaniswa sei pakati pebhaudhi netambo dzemukati. Kana kubatikana kusina kukwana, mutoro unonangana netambo shoma dzekutanga, zvichiwedzera kushushikana kwenzvimbo uye nekukasira kubviswa kweshinda kana kutyoka.

Injiniya maitiro akanakisa anowanzo kurudzira hurefu hwekuita hushoma hwe:

 

• 1.0 × bhaudhi dhayamitazvesimbi-ku-makonesheni esimbi
• 1.5 × bhaudhi dhayamita kana kupfuurakune zvinyoro zvepasi

 

Mumajoini ezvimiro akaiswa pasi pekuremerwa, kuzunguzika, kana cyclic stress, kubatanidzwa kweshinda kwakakodzera kunotonyanya kukosha pakuchengetedza preload uye kwenguva refu{0}}yakabatana kubatana.

 

 

Mukuvaka maapplication, kusakwana kwetambo kubatanidzwa kunowanzo tungamira kune akati wandei anofanofungidzira kutadza modes:

 

1. Kubvisa shinda, uko shinda dzemukati dzinogera pasi pemutoro unorema
2. Bolt dhonza-kunze, kunyanya mune anchor kana embedded application
3. Kurasika preload, zvichikonzera kutsvedza kwemajoini uye kukuvara kwekuneta
4. Progressive joint kusunungura, kuwedzera njodzi yekuchengetedza nekufamba kwenguva

 

Kukundikana uku kunowanzoitika kunyangwe -mabhaudhi esimba akashandiswa, zvichiratidza kuti giredhi resimba rega harikwanisi kutsiva kusakwana kubatanidzwa.

 

Kuwana chaiyo tambo yekubatanidzwa pane saiti zvinonetsa pane dhizaini maverengero anoratidza. Zvipingamupinyi zvinowanzoitika zvinosanganisira:

 

1. Structural tolerance stack-pakati penhengo dzesimbi

2. Yakaganhurirwa bhaudhi kureba kuwanikwa panguva yekutenga

3. Coating ukobvu kunokanganisa usable thread kureba

4. Kuisa zvipingamupinyi munzvimbo dzakasungwa kana dzakakwirira dzebasa

 

Nekuda kweizvozvo, nyaya dzekubatanidzwa kweshinda dzinowanzounzwa kwete panguva yekuisa, asi kare-panguva yezvakatemwa nekutenga.

 

 

 

Muzvirongwa zvekuvaka zvepasi rose, zviyero zveASTM zvinoramba zviri mucherechedzo wekugadzirisa mabhaudhi. Magiredhi anowanzo kutaurwa anosanganisira:

 

ASTM A325: Epakati-mabhaudhi esimbi ekabhoni ekubatanidza zvimiro

ASTM A490: High-mabhaudhi esimbi alloy alloy akakosha-anotakura majoini

 

Aya mazinga haatsananguri simba remuchina chete asiwo mativi anodikanwa, shinda fomu, uye tarisiro yekushanda, zvichiita kuti kuteera kuve kwakakosha kune kuchengetedzwa kwechimiro uye kubvumidzwa kwekuongorora.

 

 

Kune zvikwata zvekutenga uye mainjiniya, kudzora tambo yekubatana kunotanga nekusarudza iyo chaiyothread kushivirira kirasiuye kurongeka kwedimensional.

 

Standard metric structural fasteners anowanzo shandisa6g (kunze) / 6H (mukati)makirasi ekushivirira kuti ave nechokwadi chekubatana uye kugovera mutoro. Kutsauka kunopfuura kushivirira uku kunowedzera njodzi yekusaenzana kutakurwa kwekutakura uye kutadza nguva isati yakwana.

 

AtAYA Fasteners, kurongeka kwedimensional kunodzorwa zvakasimba, nekushivirira kwekugadzira kunochengetwa± 0.01 mm kusvika ± 0.005 mm, kuve nechokwadi chekufungidzira kubatanidzwa kwetambo uye kushanda kwakafanana pamapurojekiti makuru ekuvaka.

 

 

Kubatanidzwa kwetambo chinhu chakakosha asi chinowanzo tarisirwa pasi mukuita kwekusimbisa kwekuvaka. Nekunzwisisa nzira dzekutadza, kuziva-zvinetso zvesaiti, uye kutonga zvinorehwa kuburikidza nekutenga kwakakodzera uye kutevedzera mwero, mainjiniya nevatengi vanogona kuderedza zvakanyanya njodzi- dzinechekuita.

 

Nemazvo-inodzorwa kugadzira uye ruzivo rwakadzama rwemashandisirwo, AYA Fasteners inotsigira mapurojekiti ekuvaka ane zvigadziriso zvinovimbika zvakagadzirirwa kwenguva yakareba-kurongeka kwechimiro.
