Cov Txheej Txheem Xaiv Rau Cov Chains Luv Luv Hauv Nruab Nrab

Cov Txheej Txheem Xaiv Rau Cov Chains Luv Luv Hauv Nruab Nrab

Cov txheej txheem xaiv cov saw hlau luv luv hauv nruab nrab: phim cov xwm txheej ua haujlwm kom raug thiab txo cov kev pheej hmoo tom qab muag rau cov neeg faib khoom.Cov saw hlau luv luv hauv nruab nrabsiv dav hauv cov khoom siv kis me me, cov kab tsim khoom tsis siv neeg, thiab cov tshuab ua haujlwm raug vim lawv hloov tau yooj yim rau qhov chaw me me thiab teb sai. Ua tus neeg faib khoom thoob ntiaj teb, thaum pom zoo cov qauv rau cov neeg siv khoom, nws yog ib qho tseem ceeb uas yuav tsum xav txog ob qho tib si kev sib xws ntawm cov khoom siv thiab txo qhov kev pheej hmoo ntawm kev xa rov qab, kev pauv, thiab kev tsis sib haum xeeb tom qab muag los ntawm kev xaiv tsis raug. Tsab xov xwm no rhuav tshem cov laj thawj tseem ceeb ntawm kev xaiv cov saw hlau luv luv los ntawm qhov kev xav ntawm cov xwm txheej siv tau, pab koj sai thiab raug phim cov neeg siv khoom xav tau.

I. Peb Yam Tseem Ceeb Uas Yuav Tsum Tau Ua Ntej Ua Ntej Xaiv

Tus yuam sij rau kev xaiv yog "kev kho kom haum rau qhov kev daws teeb meem." Hauv cov xwm txheej luv luv, qhov chaw ntawm cov khoom siv tsawg thiab qhov yuav tsum tau ua kom raug ntawm kev sib kis yog siab. Cov ntaub ntawv tseem ceeb hauv qab no yuav tsum tau txheeb xyuas ua ntej:
Cov txheej txheem ua haujlwm tseem ceeb: Piav qhia qhov tseeb ntawm cov khoom siv (suav nrog cov khoom siv ntsuas thiab cov khoom siv cuam tshuam), qhov ceev ua haujlwm (rpm), thiab qhov kub ua haujlwm (-20 ℃ ~ 120 ℃ yog qhov ntau thiab tsawg ib txwm muaj; yuav tsum tau teev cov chaw tshwj xeeb).

Cov Lus Qhia Txog Qhov Chaw Txwv: Ntsuas qhov chaw nruab nrab ntawm qhov chaw teeb tsa thiab suav cov hniav sprocket ntawm cov khoom siv ntsuas kom paub meej qhov chaw nruj ntawm cov saw hlau (kev tso cai nruj rau qhov chaw nruab nrab luv luv feem ntau yog ≤5% kom tsis txhob ncab dhau).

Cov Kev Cai Hloov Kho Ib Puag Ncig: Xav txog qhov muaj plua plav, roj, cov tshuaj lom neeg (xws li hauv cov chaw tshuaj lom neeg), lossis cov xwm txheej ua haujlwm tshwj xeeb xws li kev pib-nres zaus siab, lossis kev cuam tshuam rov qab.

II. 4 Txoj Kev Xaiv Tseem Ceeb rau Kev Tiv Thaiv Qhov Teeb Meem Kom Zoo

1. Tus lej saw thiab qhov siab: Qhov "Qhov loj me tseem ceeb" rau qhov nrug luv ntawm qhov chaw nruab nrab
Xaiv qhov tseem ceeb raws li lub hauv paus ntsiab lus ntawm "qhov me dua, ntau kab": Nrog qhov chaw nruab nrab luv, cov saw hlau me dua (xws li 06B, 08A) muab kev ywj pheej ntau dua thiab txo qhov kev pheej hmoo ntawm kev sib tsoo; thaum lub nra tsis txaus, ua qhov tseem ceeb rau kev nce tus lej ntawm cov kab (es tsis txhob nce qhov suab) kom tsis txhob muaj kev cuam tshuam ntau dhau vim yog qhov suab loj dhau.

Tus lej saw hlau sib phim Sprocket: Xyuas kom meej tias qhov siab ntawm saw hlau sib xws nrog qhov siab ntawm sprocket ntawm cov khoom siv ntawm tus neeg siv khoom. Hauv qhov xwm txheej luv luv, nws raug pom zoo kom suav cov hniav sprocket yuav tsum yog ≥17 hniav kom txo qhov hnav ntawm saw hlau thiab qhov muaj feem yuav hla hniav.

2. Kev Xaiv Qauv: Kev Hloov Kho Rau Cov Yam Ntxim Saib Ntawm Kev Sib Kis Luv-Center-Pitch

Kev Xaiv Hom Roller: Cov saw hlau khov kho yog siv rau hauv cov ntawv thov dav dav vim lawv txoj kev tiv taus kev hnav thiab lub peev xwm thauj khoom ruaj khov; cov saw hlau hollow roller raug pom zoo rau cov xwm txheej kis tau sai lossis raug kom txo qhov cuam tshuam inertial.

Kev Sib Txuas Hom Sib Koom: Rau cov ntawv thov luv luv-qhov chaw nruab nrab nrog qhov chaw teeb tsa tsawg, cov pob qij txha caij nplooj ntoos hlav yog qhov zoo dua (rau kev yooj yim disassembly); cov pob qij txha cotter yog siv rau cov xwm txheej hnyav lossis kev sib kis ntsug kom txhim kho lub zog txuas.

Kev Txiav Txim Siab Txog Tus Naj Npawb ntawm Kab: Cov saw hlau ib kab yog qhov tsim nyog rau cov khoom siv thauj khoom me me, cov ntawv thov ceev qis (xws li cov khoom siv thauj khoom me me); cov saw hlau ob/peb kab yog siv rau cov ntawv thov thauj khoom nruab nrab mus rau hnyav (xws li cov cuab yeej siv tshuab me me), tab sis yuav tsum tau them sai sai rau qhov tseeb ntawm kab sib nrug ntawm cov saw hlau ntau kab kom tsis txhob muaj kev ntxhov siab tsis sib xws.

3. Khoom siv thiab Kev Kho Kub: Kev hloov kho rau qhov yuav tsum tau ua ntawm ib puag ncig thiab lub neej ntev

Ib puag ncig dav dav: Cov saw hlau ua los ntawm 20MnSi raug xaiv, tom qab carburizing thiab quenching kev kho mob, ua tiav qhov nyuaj ntawm HRC58-62, ua tau raws li qhov yuav tsum tau hnav tsis kam ntawm feem ntau cov ntawv thov kev lag luam.

Ib puag ncig tshwj xeeb: Rau cov chaw muaj xeb (xws li ib puag ncig sab nraum zoov thiab cov khoom siv tshuaj lom neeg), cov hlau tsis xeb (304/316) raug pom zoo; rau cov chaw kub siab (> 100 ℃), cov khoom siv alloy kub siab yuav tsum tau xaiv, nrog rau cov roj kub siab.

Cov Kev Cai Uas Muaj Zog: Rau cov xwm txheej pib-nres lossis cuam tshuam ntau zaus, xaiv cov saw hlau nrog cov menyuam phosphated thiab bushings los txhim kho lub zog qaug zog thiab kev tiv thaiv xeb.

4. Kev Hloov Kho thiab Kev Txij Nkawm: Txo Cov Nqi Ua Haujlwm ntawm Cov Neeg Siv Khoom

Xav Txog Qhov Yuam Kev Ntawm Kev Teeb Tsa: Qhov nrug luv ntawm qhov chaw nruab nrab yuav tsum tau muaj coaxiality siab thaum lub sijhawm teeb tsa. Cov saw hlau uas muaj kev kho "pre-tensioning" raug pom zoo kom txo qhov deformation tom qab teeb tsa.

Kev Hloov Kho Lubrication: Cov roj nplua nyeem siv rau hauv qhov chaw kaw, thiab cov roj nplua nyeem rau hauv qhov chaw qhib. Thaum lub saw hlau ceev ceev nrog qhov nruab nrab luv luv, nws raug pom zoo kom siv cov bushings uas muaj roj nplua nyeem rau tus kheej kom txo cov neeg siv khoom zaus saib xyuas.

Kev Txheeb Xyuas Lub Hwj Chim Tso Cai: Lub zog tso cai ntawm cov saw hlau uas muaj qhov nrug luv luv yuav txo qis thaum qhov ceev nce ntxiv. Nws yog qhov tsim nyog los txheeb xyuas lub zog tso cai raws li lub rooj "Center Distance - Speed ​​​​- Permissible Power" ntawm lub chaw tsim khoom kom tsis txhob muaj kev ua haujlwm ntau dhau.

III. Peb Qhov Yuam Kev Xaiv Uas Cov Neeg Muag Khoom Yuav Tsum Tsis Txhob Ua

Yuam Kev 1: Ua tib zoo nrhiav "lub zog siab" thiab xaiv cov saw hlau loj uas muaj ib kab. Cov saw hlau loj uas muaj qhov nruab nrab luv luv tsis muaj kev ywj pheej thiab yooj yim ua rau sprocket hnav sai dua, yog li ua rau lawv lub neej siv luv dua.

Yuam Kev 2: Tsis quav ntsej txog kev sib haum xeeb ntawm ib puag ncig thiab siv cov saw hlau ib txwm muaj nyob rau hauv qhov chaw xeb/kub heev. Qhov no ua rau xeb ua ntej lub sijhawm thiab tawg ntawm cov saw hlau, ua rau muaj kev tsis sib haum xeeb tom qab muag.

Yuam Kev 3: Tsuas yog tsom mus rau tus lej saw hlau xwb tsis xav txog qhov tseeb ntawm kev tsim khoom. Kev tsav tsheb luv luv yuav tsum muaj qhov tseeb ntawm lub suab saw hlau siab. Nws raug pom zoo kom xaiv cov saw hlau uas ua tau raws li cov qauv ISO 606 kom txo qhov kev co ntawm kev sib kis.

IV. Kev piav qhia luv luv ntawm cov txheej txheem xaiv cov saw hlau luv luv

Sau cov kev teeb tsa ua haujlwm ntawm cov neeg siv khoom (thauj khoom, ceev, kub, qhov chaw);
Ua ntej txiav txim siab tus lej saw hlau raws li "sprocket phim qhov suab + tus lej ntawm cov kab phim qhov thauj khoom";
Xaiv cov ntaub ntawv thiab cov txheej txheem kho cua sov raws li qhov chaw ib puag ncig;
Txheeb xyuas hom pob qij txha thiab cov txheej txheem lubrication raws li qhov chaw teeb tsa thiab cov kev cai txij nkawm;
Tshawb xyuas lub zog uas tso cai kom paub tseeb tias sib xws nrog cov kev cai ua haujlwm ntawm cov khoom siv.
