Ib txoj kev caij tsheb kauj vab cuam tshuam rau 80-120 lab pedal strokes dhau lawv lub neej ua haujlwm. Txhua tus mob stroke tsim torque spikes los ntawm lub drivetrain, thaum txoj kev vibration, cuam tshuam, thiab sprint loads ntxiv kev nyuaj siab cyclic. Tsis zoo li cov ntawv thov zoo li qub lossis servo, cov khoom siv tsheb kauj vab ua haujlwm nyob rau hauv siab - lub voj voog qaug zog qhov chaw pib tawg yog thawj qhov kev txhawj xeeb tsis ua haujlwm.
CNC machining los ntawm billet muab cov qauv zoo ib yam tsis muaj qhov porosity casting, txhim kho kev qaug zog ntawm cov chaw tseem ceeb xws li xov, fillets, thiab kev hloov pauv. Txawm li cas los xij, machining tuaj yeem qhia txog qhov kev ntxhov siab seem yog tias cov txheej txheem tsis raug tswj xyuas. Ntawm Ntsiab-CNC, peb txhim kho cov cuab yeej txoj hauv kev, txiav tej yam kev mob, thiab siv cov kev ntxhov siab thaum xav tau kom muaj kev ruaj ntseg thiab ntev - lub sij hawm cia siab rau.
Khoom siv -Kev Ua Haujlwm Kev Ua Haujlwm rau Kev Siv Caij Tsheb
Kev xaiv cov khoom siv rau cov khoom siv tsheb kauj vab tsis yog hais txog kev xaiv cov alloy uas muaj zog tshaj plaws - nws yog hais txog kev sib piv cov khoom siv rau cov hom tsis ua haujlwm tshwj xeeb txhua qhov ntsej muag. Hauv qab no yog peb qhov laj thawj engineering rau txhua yam khoom uas peb nquag siv tshuab:
| Khoom siv | Daim ntawv thov tsheb kauj vab | Engineering Rational |
|---|---|---|
| 7075-T6 Aluminium | Chainrings, cassette cogs, derailleur pulleys | Tawm zog 503 MPa - 40% siab dua 6061-T6; ciaj sia rov qab cuam tshuam cov hniav yam tsis muaj yas deformation; txaisHom III nyuaj anodizingrau hnav nto tiv thaiv |
| 6061-T6 Aluminium | Stems, spacers, lub raj mis cage bosses | Zoo heev corrosion kuj tiv thaiv hws thiab nag; zoo formability rau complex clamp geometry; weldable rau ncej-mounted fittings; tus nqi qis dua rau cov uas tsis yog -hu rau qhov chaw |
| Ti-6Al-4V (Qib 5) | Lub rooj zaum ncej taub hau, eeb rails, bolt hardware | Kev qaug zog zoo heev nyob rau hauv siab - lub voj voog thauj khoom, nrog kev qaug zog qis thaum ua haujlwm nyob rau hauv cov khoom tsim kev txwv; kwv yees li 43% sib zog dua hlau ntawm qhov sib piv nruj; haum rau cov neeg caij tsheb sib cuag daim ntawv thov vim nws biocompatibility. |
| 17-4PH Stainless hlau | Nres caliper lub cev, rotor kho vajtse | nag lossis daus hardening rau H900 mob (40 HRC) tom qab machining; tuav lub zog tensile ntawm nres kub kub txog 200℃nto; chloride pitting kuj zoo dua rau qib 304/316 |
| 4130 Chromoly Steel | Derailleur hangers, dropout inserts | Tsim los ua cov khoom siv fij tseg - yields kwv yees ntawm 8-12 Nm kom nqus tau lub zog ua ntej nws ncav cuag cov pa roj carbon lossis txhuas; Thaum tshav kub kub- kho kom zoo ib yam hardness rau repeatable yield tus cwj pwm |
Surface Engineering rau Corrosion -Resistant CNC Tsheb kauj vab Cheebtsam
Cov khoom siv tsheb kauj vab ua haujlwm nyob rau hauv ib puag ncig corrosion uas tsis muaj lwm yam khoom lag luam uas peb lub tshuab ntsib. Peb qhov kev hem thawj tshwj xeeb txhais ib puag ncig no:
hws - Cockpit Cheebtsam (stems, handlebar clamps, shifter mounts) yog nyob sib ze rau tus neeg caij tsheb txhais tes thiab lub ntsej muag. Tib neeg hws yog cov tshuaj chlorinated saline nrog pH ntawm 4.5 txog 6.0, nruj dua li cov av noo nyob ib puag ncig. Ntau lub hlis ntawm kev cob qhia sab hauv tsev ntawm tus kws qhia turbo, tawm hws tuaj yeem ua rau lub pob zeb liab qab mus rau qhov tob ntawm 0.3 hli - txaus los cuam tshuam kev ncaj ncees clamp.
chain lubricant- Drivetrain Cheebtsam yog da dej hauv cov roj saw, qee qhov muaj cov tshuaj ntxiv uas cuam tshuam nrog qee yam anodizing. Sulfurized heev- cov tshuaj ntxiv rau hauv cov roj ntub dej tuaj yeem tawm tsam hom II anodizing yam tsis muaj kev sib khi.
Txoj kev ntsev- Lub caij ntuj no caij ntuj no nthuav tawm txhua qhov chaw ntawm cov hlau raug chloride nres. Hlau fasteners thiab tsis muaj kev tiv thaiv aluminium corrode nyob rau hauv lub lis piam ntawm kev raug ntsev tsis tu ncua.
Peb lub tswv yim pom zoo engineering ntog:
Hom III nyuaj anodizing(40–60 μm) ntawm 7075-T6 drivetrain qhov chaw - dual hnav thiab tiv thaiv corrosion. IL: Kev pabcuam nyuaj anodizing muaj nyob hauv tsev.
Electropolishingntawm 17-4PH stainless nres qhov chaw - tshem tawm cov txheej txheem passive ntawm qhov tsis xws luag thiab tsim cov chromium-enriched nto uas tiv thaiv chloride pitting.
Electroless npib tsib xee platingntawm steel fasteners ntawm rider contact point - muab galvanic cais ntawm steel bolts thiab aluminium interfaces, tiv thaiv galvanic cell uas accelerates corrosion.
Hmoov txheej ntawm tsis yog -thov cov khoom siv thav duab (lub raj mis cage bosses, cable nres) - UV thiab cuam tshuam rau sab nrauv-mounted qhov chaw.
