1. Hordhac: Bolt-ka isku haya Mashiinnada

Ku dhex lugee dukaan kasta oo mishiin ah, unug robot ah, ama nacele marawaxadaha dabaysha waxaadna ka heli doontaa xidhe isku mid ah: xadhig madax cylindrical ah oo leh nasasho lix geesood ah, oo lagu adkeeyey furaha Allen. Tani waa daboolka madaxa godka hexagon, loo qoondeeyey sida DIN 912 iyo ISO 4762. Waa boodhka caadiga ah ee loogu talagalay caaryada dhinta, qalabka mashiinka, manifolds hydraulic, iyo shirarka saxda ah, sababtoo ah waxay xoogga saartaa culeyska sare ee baqshadda is haysta waxaana lagu celin karaa counterbore.

2. Qeexida alaabta: Hexagon Socket Head Cap Screw

Joometry ee boolkan waxa loo hagaajiyey horudhac, ee maaha muuqaal nadiif ah:

Madaxa cylindricaloo leh weji siman oo u qaybiya culayska isku xidhka meel wareeg ah oo buuxa.
godka lix geesoodka gudaha(mitirka dabaqyada-dhaafka ah ee 2.5 mm ilaa 36 mm), gudbinta qulqulka iyada oo loo marayo lix weji oo leh kama-bax yar.
dunta mitirka ah ee qaab-buuxa(Garoonka qallafsan ama ganaaxa marka loo eego ISO 261), duuban halkii laga jari lahaa socodka hadhuudhka joogtada ah iyo nolosha daalka wanaagsan.
Fasalada hantida 8.8, 10.9, iyo 12.9, oo daboolaya xoogga xajinta laga bilaabo 800 ilaa 1,220 MPa.

Saamiga madaxa-ilaa-thread arrimaha naqshadeynta daxalka: madaxa cylindrical weyn siinayaa daahan ballaaran, dusha stress hoose si ay ugu xidhmaan, halka nasasho godka qoto dheer waa aagga ugu daahan-muhiimka ah ee furka oo dhan - waa meesha miridhku ugu horrayn weerarro iyo meesha filim khafiif ah ama aan dhamaystirnayn uu keeno bolt si ay u qabsadaan.

3. Rakibaadda: Torque, Preload, iyo Isdhexgalka Dahaarka

Daboolka u adkaysta daxalka waa wax aan qiimo lahayn haddii wadajirku furmo. Jadwalka 2 waxa uu siinayaa wareegga fadhiga ee fasalka 8.8 iyo 10.9 godka koofiyada madaxa oo leh daahan Dacromet (μ ≈ 0.14).

Isticmaal furaha saxda ah.Furaha Allen ee xiran ama aan la qiyaasi karin ayaa dhaawac u geysta godka wuxuuna soo bandhigaa birta qaawan - meesha saxda ah ee daxalka ka bilowdo.
Ixtiraamka ka-hortagga.Madaxu wuxuu ku fadhiyaa wejigiisa buuxa; kabo-ka-soo-baxa oo la jarjaray ama burburay wuxuu yareeyaa aagga xiriirka wuxuuna dillaaci karaa filimka dahaarka ah ee culeyska saaran.
Ha isku darin hababka daahanisku mid ah oo isku mid ah iyada oo aan dib loo hubin qulqulka. Dacromet-ku-xiran ee looska cad wuxuu leeyahay khilaaf ka duwan kan daboolan ee looska dahaaran.
Dib-u-rogid ka dib dejintagaasaska jilicsan ama guryaha caagga ah; filimka engegan ma gurguurto, laakiin walxaha isku xidhan ayaa laga yaabaa.

4. Gabagabo

Xirmada daboolka leh ee hexagon-ka daboolka ah waa qayb yar oo go'aamisa nolosha adeegga shirka weyn. Madaxiisa cylindrical iyo hexagon gudaha ah ayaa keenaya culeyska xajinta baahida mashiinada casriga ah; dahaadhkeeda zinc-aluminium flake waxay bixisaa waxqabadka ka-hortagga daxalka ee bannaanka, badda, iyo adeegga gaadiidka ay u baahan yihiin - iyada oo aan la isku dhejin hydrogen, iyada oo aan dunta dib loo taaban, iyo iyada oo aan lahayn ciqaabta xamaasadda leh ee birta ah. Si sax ah u qeex dhismaha si sax ah, si sax ah u rux, boodhkuna waxa uu ka dheerayn doonaa rinjiga mishiinka uu wada hayo.

Ma Hayso. Xiga.
