Hauv lub tshuab khawb av txoj kev mus ncig, qhov tsav kawg yog qhov chaw ntawm lub zog thiab lub sprocket yog qhov chaw tawm. Ob qho tib si tau koom ua ke los ntawm lub nplhaib ntawm cov bolts, tsim cov kev sib txuas siab tshaj plaws ntawm tag nrho lub tshuab.
Muaj ntau tus tswv siv lub sprocket ua ib yam khoom pheej yig thiab hloov nws yam tsis xav txog. Qhov tseeb, kev sib phim ntawm lub sprocket thiab lub cav kawg tsis raug feem ntau yuav ua rau koj raug mob tag nrho. Tsab xov xwm no qhia txog "Txoj Cai Sib Tw Peb Qib" los pab koj nkag siab txog qhov kev sib raug zoo no kom meej.
I. Theem Ib: Kev Sib Txuas Lus Sib Txuas Lus (Puas yuav haum - thiab nws puas yuav zaum zoo?)
Txheej yooj yim tshaj plaws, thiab yooj yim tshaj plaws kom ua yuam kev. Kev sib txuas ntawm sprocket-rau-zaum kawg-tsav muaj plaub qhov tseem ceeb:
| Khoom Sib Xws | Kev piav qhia | Qhov tshwm sim ntawm kev tsis sib haum xeeb |
| Tus qauv ntsia hlau & PCD | Lub voj voog ntawm lub bolt thiab qhov suav ntawm qhov yuav tsum sib phim raws nraim | Yuav tsis mount; yuam reaming ua rau off-center loading |
| Lub cheeb ntawm kev sau npe | Qhov chaw haum ntawm lub sprocket bore thiab lub flange tso zis kawg | Kev tshem tawm ntau dhau ua rau puas tsuaj rau qhov sib npaug, ua rau muaj kev co eccentric thaum ua haujlwm |
| Cov lus qhia tshwj xeeb thiab qib ntawm lub pob ntsia hlau | Txoj kab uas hla, ntev, qib zog (piv txwv li, Chav Kawm 10.9 / 12.9) | Hloov cov bolts txheem rau cov bolts muaj zog siab → kev ua haujlwm qaug zog |
| Flange flatness & offset | Qhov chaw sib phim thiab axial offset ntawm sprocket thiab flange | Kev sib cuag tsis zoo ua rau lub bolt preload lwj thiab ua rau cov foob pob tawg |
II. Qib Ob: Kinematic Match (Puas yog nws mus ncig ntawm qhov ceev kom raug, raug?)
Tus lej hniav ntawm lub sprocket × qhov siab txiav txim siab nws "lub vojvoog dov zoo," uas txiav txim siab qhov ceev mus ncig ncaj qha.
Kev sib raug zoo tseem ceeb (lub tswv yim):
Qhov ceev mus ncig ∝ qhov ceev kawg ntawm qhov tso zis × lub vojvoog zoo ntawm sprocket Lub vojvoog zoo ntawm sprocket ≈ lub suab × suav cov hniav ÷ (2π)
Yog li ntawd, ib txoj cai hlau: Thaum hloov lub sprocket, tus lej hniav yuav tsum sib xws nrog tus thawj.
| Hloov pauv | Qhov tshwm sim |
| Ntau cov hniav | Kev mus ncig sai dua, kev siv zog rub qis dua; kev hloov pauv ntawm lub kaw lus hydraulic, hloov pauv cov yam ntxwv ntawm lub cev muaj zog thauj khoom |
| Cov hniav tsawg dua | Kev mus qeeb qeeb, kev siv zog rub ntau dua; tej zaum yuav ua rau cua sov hydraulic thiab siv roj ntau dua |
| Lub suab tsis raug | Kev sib txuas tsis zoo ntawm cov saw hlau, kev cuam tshuam hnyav, thiab kev puas tsuaj sai ntawm ob qho saw hlau thiab sprocket |
III. Qib Peb: Kev Sib Tw Dynamic (Nws puas tuaj yeem nqus tau qhov kev poob siab?)
Cov txheej uas tsis tau saib xyuas tshaj plaws - thiab qhov uas muaj feem cuam tshuam loj tshaj plaws rau lub neej tsav kawg.
Qhov "fuse effect": Lub sprocket yog thawj qhov khoom hauv lub zog saw hlau kom ntsib kev cuam tshuam sab nraud. Thaum cov hniav profiles zoo, kev sib koom tes nrog cov saw hlau bushings yog tas mus li thiab du. Tab sis thaum cov hniav hnav mus rau hauv "shark fin" (scalloped / hooked), kev sib koom tes ua rau hammering tsis tu ncua.
Cov kev cuam tshuam no mus rau sab saud los ntawm cov zis flange → cov zis ncej → tus neeg nqa khoom → iav → cov kabmob loj, thaum kawg tshwm sim li:
-Cov iav thoob ntiaj teb puas thiab cov hniav tawg;
- Kev sib tw spalling;
- Kev ua tsis tiav ntawm lub foob ntawm lub qhov tso zis vim yog kev co, ua rau muaj roj xau.
Yog li ntawd, lub sprocket yog qhov tseem ceeb "fuse": pheej yig rau hnav tawm, tab sis nws nqus txhua qhov kev cuam tshuam rau lub zog tsav kawg. Hloov nws sai li sai tau thaum cov hniav pib ntse yog qhov kev nqis peev zoo tshaj plaws uas koj tuaj yeem ua tau los tiv thaiv koj lub zog tsav kawg.
IV. Hom Sprocket: Ib Daim vs. Segmented
| Hom | Cov yam ntxwv | Zoo Tshaj Plaws Rau |
| Ib Daim | Cast/forged ua ib chav tsev; rigidity siab, concentricity zoo, tus nqi qis dua | Cov tshuab khawb me thiab nruab nrab, cov xwm txheej ib txwm muaj |
| Ntug Ntug Sib Cais | Rim siv ntau ntu bolted; cov ntu hnav hloov pauv ib tus zuj zus | Cov tshuab loj thiab cov kev siv mining/hnyav nrog kev txuag nyiaj zoo dua |
Lus Cim: Nrog cov rims uas tau faib ua ntu, qhov tseeb ntawm cov pob qij txha ntawm cov ntu yog qhov tseem ceeb heev. Cov pob qij txha uas tsis sib dhos ua rau cov saw hlau "dhia cov hniav," ua rau muaj kev poob siab ncaj qha mus rau hauv qhov tsav kawg.
V. Daim Ntawv Teev Xyuas Kev Tshuaj Xyuas & Kev Txij Nkawm
| Khoom | Txoj Kev | Tus Qauv Kev Txiav Txim |
| Kev hnav cov hniav profile | Kev sib piv ntawm cov duab thiab cov qauv | Hloov thaum cov lus qhia pom tseeb tias muaj qhov hooking / sharpening |
| Qhov tuab ntawm cov hniav | Kev ntsuas qhov dav ntawm lub taub hau caliper | Hloov thaum qis dua 25% ntawm thawj |
| Lub zog ntswj | Rov xyuas dua nrog lub torque wrench | Yuav tsum ua raws li cov lus qhia ntawm phau ntawv qhia |
| Cov kab nrib pleb ntawm cov qhov bolt | Kev tshuaj xyuas pom + xim nkag mus | Yog muaj qhov tawg → hloov lub sprocket tam sim ntawd |
| Kev sau npe kom haum | Lub ntsuas qhov ntsuas | Yog tias tsis kam lees ces txhais tau tias flange lossis sprocket hnav lawm |
| Cov hniav tsis sib npaug | Saib xyuas tus qauv kev sib cuag | Kev hnav ib sab qhia tias kev sib dhos tsis zoo lossis kev hloov pauv ntawm lub tshuab |
Hloov lub suab: Tsis txhob muab lub sprocket qub tso rau ntawm txoj saw tshiab. Txoj saw tshiab muaj lub suab meej, thiab cov hniav uas txuas ntawm lub sprocket qub yuav zom cov bushings tshiab tam sim ntawd - qhov xwm txheej ib txwm muaj ntawm "txuag pennies, poob ntau txhiab."
VI. Daim Ntawv Teev Cov Khoom Siv
Thaum xaj lub sprocket, ib txwm muab cov hauv qab no:
1. Qauv tshuab + xyoo;
2. Suav cov hniav — yuav tsum phim cov hniav qub;
3. Kev qhia tshwj xeeb;
4. suav qhov ntsia hlau thiab PCD;
5. Sau npe txoj kab uas hla;
6. Ib daim los yog segmented;
7. Sib phim tus qauv tsav kawg (yog tias hloov ob qho tib si).
Ua ib lub tuam txhab muag khoom siv hnyav, GT (Xiamen Globe Truth) ceeb toom koj: lub sprocket thiab lub tshuab tsav kawg tsim ib qho kev sib txuas thiab lub cev thauj khoom - qhov xwm txheej ntawm ob qho cuam tshuam rau lwm qhov. Peb xav kom tshuaj xyuas lub foob ntawm lub qhov tso zis kawg ntawm lub tshuab tsav kawg thiab cov qhov ntsia hlau thaum hloov lub sprocket, thiab soj ntsuam lub neej seem ntawm lub sprocket thiab saw thaum hloov lub tshuab tsav kawg.
Xaus lus
Ib lub sprocket tsis kim - tab sis nws txiav txim siab qhov txoj hmoo ntawm koj qhov kev tsav tsheb kawg. Tau txais qhov Three-Level Match kom raug - mount nws kom raug, phim cov hniav suav, thiab nqus qhov poob siab - thiab ib feem uas raug nqi kaum tawm daus las yuav tiv thaiv kev sib dhos uas muaj nqis ntau txhiab.
