Болты с полной и неполной резьбой: руководство по применению промышленного крепежа 

1. Nguva Yekushandisa Yakazara Thread Bolts

Mabhaudhi akazara eshinda anokunda mumashandisirwo uko kunodiwa kubatanidzwa kweshinda. Heano maitiro ekutanga:

Thin-Wall Assemblies: Kana uchisungirira mahwendefa matete, mashiti, kana zvikamu uko kureba kwese kwekubata kuri kupfupi, shinda dzakazara dzinovimbisa kubatanidzwa kwakakwana kweiyo torque yekusimbisa.

Tapped Hole Connections: Kana bhaudhi richinge rapinda mugomba rakatepwa (rine shinda) pane kushandisa nati, shinda dzakazara dzinopa simba rekubata mukati mehudzamu hwezvinhu zviripo.

Kugadzirisa uye Clamping: Muzvigadziriso, jigs, uye magungano anogadziriswa apo bhaudhi rinoshanda sechinhu chinosungirira kana chekumisa, tambo dzakazara dzinobvumira kuenderera kugadziridzwa pamwe nehurefu hwose.

Shear-Dominant Joints: Mukubatana uko bhaudhi rinonyanya kurwisa mauto ekugera kwete mitoro inorema, tambo dzakazara dzinoita nemazvo nekuti iyo shinda yakachinjika-chikamu inobata zvizere nenhengo dzese dzakabatana.

Diki-Diameter Fasteners (< M16): Kune mabhaudhi uye screws pazasi M16 dhayamita uye pasi pe100 mm kureba, yakazara shinda ndiyo yakasarudzika yekugadzira uye inokodzera yakawanda-yechinangwa maapplication.

2. Nguva Yekushandisa Partial Thread Bolts

Chikamu chetambo mabhoti ndiyo inosarudzika sarudzo kana kutendeseka kwakabatana kunoenderana nekutakurwa kwemutoro chaiwo kuburikidza nebhaudhi shank. Mamiriro ekushandisa akakosha anosanganisira:

Structural Steel Connections: Heavy hex bolts (ASTM A325, A490, A193 B7) anoshandiswa muzvivakwa, mabhiriji, uye shongwe zvinoda shank yakatsetseka kuti irambe kugera mundege yakabatana. Iyo isina kuverengerwa grip chikamu inopa yakazara-diameter inotakura nzvimbo, yakakosha kune inotsvedza-yakakosha kubatana.

High-Tension Bolting (> 100 mm Kureba): Kune mabhaudhi anodarika 100 mm, chidimbu chidimbu chinodzikisira kusagadzikana pamudzi weshinda mundege yekugera. Iyo shank yakatsetseka inogovera clamping simba zvakaenzana panhengo dzakabatana.

Piping uye Flange Assemblies: Mabhaudhi eFlange (DIN 6921, ASME B18.2.1) anoshandisa tambo yechidimbu kuchengetedza kurongeka kwechokwadi mukubatana kweflange. Iyo shank inoshanda senge dowel yekuwana, ichidzivirira kufamba kwehukama pakati peflanges pasi pekumanikidza bhasikoro.

Kutenderera uye Dynamic Mitoro: Mumichina ine vibration kana cyclic kurodha, iyo isina kuverengerwa shank inodzivirira kusagadzikana kupfeka uye inoderedza njodzi yekuneta kutsemuka kutanga pamidzi yeshinda.

Anti-Corrosion Applications: Kune inopisa-dip galvanized (HDG), dacromet, kana PTFE-yakavharwa mabhaudhi, shank yakatsetseka inogamuchira kupfekedzwa zvakanyanya kupfuura zvikamu zvakarukwa, ichipa kuchengetedzwa kwepamusoro kwecorrosion panzvimbo yakaoma inotakura mutoro.

Zvishandiso Zvinorema uye Migodhi: High-simba mabhaudhi (Giredhi 8.8, 10.9, 12.9) mune zvekuchera, macrusher, uye maconveyor masisitimu anovimba nechidimbu shinda dhizaini kubata yakasanganiswa shear uye inorema mitoro munzvimbo dzakaoma.

3. Kuenzanisa Kukurumidza: Yakazara Thread vs. Partial Thread
