Kev Kawm Txog Qhov Teeb Meem: Kev Txhim Kho Kom Ruaj Khov ntawm Cov Chains Rau Cov Tsheb Kauj Vab

Tsheb kauj vabcov saw hlauyog "txoj kab cawm siav" ntawm lub drivetrain, thiab lawv qhov ruaj khov ncaj qha txiav txim siab txog kev caij tsheb kauj vab thiab kev nyab xeeb. Kev pib thiab nres ntau zaus thaum lub sijhawm mus los hauv nroog ua rau cov saw hlau hnav sai dua, thaum qhov cuam tshuam ntawm av nkos thiab xuab zeb ntawm thaj chaw tawm ntawm txoj kev tuaj yeem ua rau cov saw hlau tsis ua haujlwm ua ntej. Cov saw hlau ib txwm muaj feem yuav tsum tau hloov tom qab tsuas yog 5,000 mais xwb. Bullead, nrog ntau xyoo ntawm kev paub hauv kev tsav tsheb, tsom mus rau "kev daws cov kev xav tau kev ruaj khov ntawm cov neeg caij tsheb thoob ntiaj teb." Los ntawm kev txhim kho thev naus laus zis peb-seem hauv cov ntaub ntawv, cov qauv, thiab cov txheej txheem, lawv tau ua tiav qhov kev dhia zoo hauv kev ruaj khov ntawm cov saw hlau maus taus. Cov ntaub ntawv kawm hauv qab no rhuav tshem cov laj thawj thiab cov txiaj ntsig ntawm kev siv thev naus laus zis no.

I. Kev Txhim Kho Cov Khoom Siv: Tsim Kom Muaj Lub Hauv Paus Ruaj Khov Rau Kev Hnav Thiab Kev Cuam Tshuam

Lub hauv paus ntawm kev ruaj khov pib nrog cov ntaub ntawv. Cov saw hlau maus taus ib txwm siv cov hlau qis-carbon nrog qhov nyuaj ntawm qhov chaw qis (HRC35-40), ua rau lawv yooj yim rau cov saw hlau deformation thiab pin hnav thaum muaj kev thauj khoom ntau. Txhawm rau daws qhov teeb meem no, Bullead thawj zaug tsim kho tshiab ntawm qhov chaw ntawm cov ntaub ntawv:

1. Kev Xaiv Cov Hlau Alloy Uas Muaj Peev Xwm Siab
Siv cov hlau sib xyaw ua ke uas muaj cov pa roj carbon ntau (hloov cov hlau uas muaj cov pa roj carbon tsawg ib txwm muaj). Cov khoom siv no muaj 0.8% -1.0% carbon thiab tau ntxiv chromium thiab molybdenum los ua kom cov qauv metallographic zoo dua - chromium txhim kho kev tiv thaiv kev hnav ntawm qhov chaw, thiab molybdenum txhim kho lub zog ntawm lub hauv paus, tiv thaiv cov saw hlau kom tsis txhob tawg vim yog "nyuaj thiab tawg yooj yim." Piv txwv li, Bullead ANSI tus qauv 12A maus taus cov saw hlau siv cov khoom siv no rau nws cov phaj saw hlau thiab cov pins, ua rau muaj kev nce 30% ntawm lub zog yooj yim piv rau cov saw hlau ib txwm muaj.

2. Kev Siv Tshuab Kho Kub Uas Muaj Kev Ntsuas Zoo

Kev siv cov txheej txheem carburizing thiab quenching + low-tempering tau txais yuav: cov khoom saw hlau raug muab tso rau hauv lub cub tawg carburizing kub 920 ℃, tso cai rau cov pa roj carbon kom nkag mus rau txheej saum npoo ntawm 2-3 hli, ua raws li 850 ℃ quenching thiab 200 ℃ low-tempering, thaum kawg ua tiav qhov sib npaug ntawm "qhov chaw tawv thiab lub plawv tawv" - qhov nyuaj ntawm qhov chaw ntawm lub phaj saw hlau ncav cuag HRC58-62 (tsis yooj yim hnav thiab khawb), thaum lub plawv tawv tseem nyob ntawm HRC30-35 (tsis yooj yim cuam tshuam thiab tsis yooj yim deform). Kev txheeb xyuas qhov tseeb: Hauv thaj chaw sov ntawm Southeast Asia (qhov nruab nrab txhua hnub kub 35 ℃ +, pib-nres ntau zaus), lub neej ua haujlwm nruab nrab ntawm 250cc maus taus uas muaj cov saw hlau no tau nce ntxiv los ntawm 5000 km rau cov saw hlau ib txwm mus rau ntau dua 8000 km, tsis muaj kev hloov pauv tseem ceeb ntawm cov phaj saw hlau.

II. Kev Tsim Kho Tshiab: Kev daws ob qhov teeb meem loj ntawm kev poob ntawm "Kev sib txhuam thiab kev xau"

70% ntawm cov saw hlau tsis ua haujlwm yog los ntawm kev sib txhuam qhuav los ntawm "kev poob lubrication" thiab "kev nkag mus rau hauv qhov tsis huv." Bullead txo qis ob hom kev poob no los ntawm kev ua kom zoo dua qub:

1. Tsim Ob Chav-Sealing Leak-Proof
Tso tseg cov foob O-ring ib txwm muaj, nws siv cov qauv sib xyaw ua ke ntawm O-ring + X-ring: O-ring muab kev sib khi yooj yim, tiv thaiv cov av loj thiab xuab zeb kom tsis txhob nkag mus; X-ring (nrog rau ntu "X" zoo li tus ntoo khaub lig) txhim kho qhov haum nrog cov pins thiab cov phaj saw hlau los ntawm daim di ncauj ob sab, txo cov roj poob vim kev co. Tib lub sijhawm, "beveled grooves" tau tsim ntawm ob qho kawg ntawm lub tes tsho, ua rau lub foob tsis yooj yim poob tawm tom qab ntxig, txhim kho cov nyhuv sealing los ntawm 60% piv rau cov qauv ib txwm muaj. Qhov xwm txheej sim tiag tiag: Caij hla teb chaws hauv European Alps (40% txoj kev xuab zeb), cov saw hlau ib txwm muaj qhia txog kev poob roj thiab kev sib tsoo ntawm cov menyuam tom qab 100 kilometers; thaum Bullead saw hlau, tom qab 500 kilometers, tseem khaws cia ntau dua 70% roj hauv lub tes tsho, tsis muaj xuab zeb nkag mus.

2. Lub Taub Roj Zoo Li Tus Pin + Tsim Txoj Kab Micro-Oil: Tau txais kev tshoov siab los ntawm cov ntsiab cai roj nplua nyeem ntev hauv thaj chaw kis, Bullead suav nrog lub taub roj cylindrical (0.5ml ntim) sab hauv tus pin, nrog rau peb txoj kab micro-roj 0.3 hli txoj kab uas hla tau tho rau hauv phab ntsa pin, txuas lub taub roj rau qhov sib txhuam ntawm phab ntsa sab hauv ntawm lub tes tsho. Thaum lub sijhawm sib dhos, cov roj kub siab, kav ntev (qhov kub thiab txias -20 ℃ txog 120 ℃) ​​raug txhaj tshuaj. Lub zog centrifugal tsim los ntawm kev sib hloov ntawm cov saw hlau thaum caij tsheb kauj vab thawb cov roj raws cov kab micro-roj, txuas ntxiv rov ua kom qhov sib txhuam ntawm qhov chaw thiab daws qhov teeb meem ntawm "kev ua tsis tiav ntawm lubrication tom qab 300km nrog cov saw hlau ib txwm muaj." Kev sib piv cov ntaub ntawv: Hauv kev sim caij tsheb kauj vab ceev ceev (80-100km / teev), Bullead saw hlau tau ua tiav lub voj voog roj nplua nyeem zoo ntawm 1200km, peb zaug ntev dua li cov saw hlau ib txwm muaj, nrog 45% txo qis ntawm kev hnav ntawm tus pin thiab lub tes tsho.

III. Kev Tsim Khoom Uas Zoo Tshaj Plaws + Kev Hloov Kho Qhov Xwm Txheej Ua Haujlwm: Ua Kom Muaj Kev Ruaj Khov Rau Ntau Yam Xwm Txheej Sib Txawv

Kev ruaj khov tsis yog ib qho cim qhia txog kev siv ib qho xwb; nws yuav tsum tau hloov kho kom haum rau cov kev xav tau ntawm ntau yam kev caij tsheb sib txawv. Bullead ua kom muaj kev ua haujlwm ruaj khov hauv ntau yam kev ua haujlwm los ntawm "kev tsim khoom kom raug rau qhov raug siab + kev ua kom zoo raws li qhov xwm txheej":

1. Kev Sib Dhos Tsis Siv Neeg lav qhov Meshing Precision
Siv lub tshuab CNC sib dhos ua ke, qhov pitch ntawm cov saw hlau, qhov sib npaug ntawm cov menyuam, thiab qhov sib npaug ntawm tus pin raug saib xyuas lub sijhawm tiag tiag: qhov yuam kev ntawm qhov pitch raug tswj tsis pub dhau ± 0.05 hli (tus qauv kev lag luam yog ± 0.1 hli), thiab qhov yuam kev ntawm cov menyuam yog ≤ 0.02 hli. Qhov kev tswj hwm siab no ua kom "tsis muaj qhov load tawm ntawm qhov chaw" thaum cov saw hlau sib txuas nrog lub sprocket - zam kev hnav ntau dhau ntawm ib sab ntawm lub phaj saw hlau uas tshwm sim los ntawm kev sib txawv ntawm cov saw hlau ib txwm muaj, ua rau lub neej ntev dua 20%.

2. Kev Rov Ua Dua Khoom Raws Li Qhov Xwm Txheej

Txhawm rau daws cov kev xav tau ntawm kev caij tsheb sib txawv, Bullead tau tsim ob yam khoom tseem ceeb:
* **Tus Qauv Mus Los Hauv nroog (piv txwv li, 42BBH):** Txoj kab uas hla ntawm lub log tsheb zoo tshaj plaws (nce ntawm 11.91mm mus rau 12.7mm), ua kom thaj chaw sib cuag nrog lub sprocket nce ntxiv, txo qhov hnyav ib cheeb tsam, hloov kho rau cov xwm txheej hauv nroog uas pib-nres ntau zaus, thiab txuas lub neej ntev dua 15% piv rau tus qauv yooj yim;
* **Qauv Tawm Txoj Kev:** Cov phaj saw hlau tuab dua (qhov tuab nce ntawm 2.5mm mus rau 3.2mm), nrog rau kev hloov pauv ntawm cov ntsiab lus tseem ceeb (txo qhov kev ntxhov siab), ua tiav lub zog tensile ntawm 22kN (tus qauv kev lag luam 18kN), muaj peev xwm tiv taus cov khoom hnyav hauv kev caij tsheb tawm txoj kev (xws li pib nce toj thiab tsaws ntawm cov toj siab). Hauv kev sim tawm txoj kev hauv hav zoov Australian, tom qab 2000 mais ntawm kev caij tsheb siab, cov saw hlau tsuas yog qhia txog 1.2% qhov ntev ntawm lub suab (qhov txwv hloov yog 2.5%), tsis tas yuav tsum tau saib xyuas thaum mus ncig.

IV. Kev Ntsuas Hauv Lub Ntiaj Teb Tiag: Kev Ntsuas Kev Ruaj Khov Hauv Cov Xwm Txheej Thoob Ntiaj Teb
Kev txhim kho thev naus laus zis yuav tsum tau lees paub hauv kev siv tiag tiag. Bullead, koom tes nrog cov neeg muag khoom thoob ntiaj teb, tau ua qhov kev sim hauv thaj chaw 12 lub hlis uas suav nrog ntau yam huab cua thiab txoj kev: Tropical Kub thiab Humid Scenarios (Bangkok, Thaib teb): 10 lub tsheb kauj vab 150cc commuter, nrog rau kev caij tsheb nruab nrab txhua hnub ntawm 50 kilometers, tau ua tiav lub neej saw hlau nruab nrab ntawm 10,200 kilometers yam tsis muaj xeb lossis tawg. Txias thiab Kub Qis Scenarios (Moscow, Russia): 5 lub tsheb kauj vab 400cc cruiser, caij hauv ib puag ncig txij li -15 ° C txog 5 ° C, tsis pom muaj saw hlau jamming vim yog siv cov roj qis-freezing-point (tsis khov ntawm -30 ° C), ua tiav lub neej saw hlau ntawm 8,500 kilometers. Cov Xwm Txheej Tawm Ntawm Roob Hav Zoov (Cape Town, South Africa): 3 lub tsheb kauj vab tawm ntawm txoj kev 650cc, uas tau caij tsheb kauj vab ntawm txoj kev xuab zeb tau 3,000 mais, tseem muaj zog tensile tau 92% ntawm lawv cov saw hlau thawj zaug, nrog rau kev hnav ntawm cov menyuam tsuas yog 0.15 hli xwb (tus qauv kev lag luam 0.3 hli).

Xaus Lus: Kev ruaj khov yog qhov tseem ceeb "kev txhim kho tus nqi ntawm tus neeg siv." Bullead qhov kev tawg hauv kev ruaj khov ntawm cov saw hlau maus taus tsis yog tsuas yog teeb meem ntawm kev sib sau ua ke ntawm cov thev naus laus zis, tab sis yog kev ua kom zoo dua "los ntawm cov ntaub ntawv mus rau qhov xwm txheej" - daws cov teeb meem tseem ceeb ntawm "kev hnav yooj yim thiab xau" los ntawm cov ntaub ntawv thiab cov qauv, thaum ua kom ntseeg tau tias cov thev naus laus zis siv tau los ntawm kev tsim khoom raug thiab kev hloov kho qhov xwm txheej. Rau cov neeg caij tsheb thoob ntiaj teb, lub neej ntev dua (qhov nruab nrab nce ntau dua 50%) txhais tau tias cov nqi hloov pauv qis dua thiab lub sijhawm tsis ua haujlwm, thaum kev ua tau zoo dua txo qhov kev phom sij ntawm kev nyab xeeb thaum caij tsheb.
