Cov kiv cua muaj kev lag luam, txoj siv conveyor lub menyuams, cov tshuab ua liaj ua teb gearboxes‌.

2. cov kabmob tapered rau cov menyuam

• cov qauv me thiab nruab nrab (xws li 30205):

Lub log tsheb, cov iav kis, cov cuab yeej siv tshuab spindles.

• qhov loj me (xws li 30310):

Cov tshuab siv hauv kev tsim kho (lub log tsheb excavator), lub ncej tseem ceeb ntawm lub tshuab tsoo, lub tsheb thauj khoom hnyav sib txawv.

3. Cov kabmob cylindrical roller (NN/NU series)

• NN3020K (ob chav kem):

Tshuab cuab yeej spindle, high-speed motor rotor, precision rolling mill caj dab.

• Tam sim no series:

Kev txhawb nqa stator lub cev muaj zog loj, lub thawv qag tsheb ciav hlau.

Cov cai tseem ceeb ntawm kev faib khoom lag luam:

1. Kev lag luam tsheb (suav txog 43%)

Cov kabmob hub (cov kabmob tapered roller), cov kabmob generator (cov kabmob pob sib sib zog nqus), cov kabmob gearbox (cov kabmob pob sib cuag angular)

2. Zog thiab kev lag luam hnyav

Lub zog cua turbine tseem ceeb (tus kheej-aligning roller bearings), thermal fais fab unit (cylindrical roller bearings)

3. Cov khoom siv siab heev

Lub cav dav hlau lub ntsiab ncej (ceramic pob bearings), high-speed rail gearbox (high-speed precision bearings).

Lub tswv yim xaiv: Cov bearings ntawm tib tus qauv yuav siv tau rau hauv ntau qhov xwm txheej vim lawv cov qib precision (P5 / P4). Piv txwv li, cov cuab yeej siv tshuab spindles xav tau cov bearings precision ntawm qib P4 lossis siab dua. Cov bearings fais fab cua xav tau kev tsim tshwj xeeb tiv thaiv xeb thiab kev pabcuam lub neej. Rau cov qauv tshwj xeeb, thov saib phau ntawv qhia kev tsim khoom.

Cov kev cai tseem ceeb rau kev ua haujlwm ntawm cov kabmob sib txawv ntawm ntau yam lag luam, feem ntau yog tsom mus rau qhov ntev xws li kev ua kom raug, kev sib hloov ceev, lub peev xwm thauj khoom, thiab kev hloov pauv ib puag ncig.

Kev lag luam tsheb

1. Cov kabmob tsav lub cev muaj zog tshiab: Lawv yuav tsum muaj qhov ceev tshaj plaws (dm • n tus nqi ≥ 70,000 mm · r / min), tiv taus kub siab (> 150 ℃), thiab tiv taus kev co siab. Cov ntaub ntawv yuav tsum muaj kev ruaj khov siab, thiab lub tshuab roj yuav tsum hloov kho rau cov xwm txheej ua haujlwm nyuaj ntawm lub cev muaj zog.

1. Cov kabmob cav ib txwm muaj: Cov kabmob tensioner pulley thiab idler pulley yuav tsum muaj lub zog ruaj khov thiab suab nrov tsawg kom ua tau raws li qhov yuav tsum tau ua kom muaj kev sib kis zoo raws li kev txuag hluav taws xob ntawm lub cav.

3. Cov kabmob hub: Cov kabmob tapered roller yuav tsum tiv taus cov khoom thauj ob sab thaum ua tau raws li qhov yuav tsum tau ua ntawm kev tsim qauv sib dua thiab lub neej ntev (xws li ntau dua 1 lab kilometers).

Kev tsav dav hlau

1. Kev txwv qhov tseeb: Qhov kam rau siab ntawm cov kabmob cav aero yuav tsum yog ≤0.005 millimeters (5 microns), thiab cov qauv tub rog txawm tias xav tau qhov tseeb ntawm 0.1 microns.

2. Kev kam rau ib puag ncig hnyav heev:

• Cov kabmob qhov chaw yuav tsum tiv taus qhov kub siab thiab qis (-180 ℃ txog 300 ℃), hluav taws xob thiab muaj cov pa roj tsawg.
• Siv cov khoom siv ceramic lossis perfluoropolyether (PFPE) lubricants los daws qhov teeb meem lubrication ntawm lub tshuab nqus tsev.

3. Kev Ntseeg Tau: Qhov yuav ua tsis tiav 20,000 revolutions ib feeb).

Kev Lag Luam Zog thiab Hnyav

1. Lub zog ntawm lub cav turbine tseem ceeb:

Cov kabmob kheej kheej uas sib dhos ua ke yuav tsum tiv taus qhov muaj zog ntawm cua thiab lub sijhawm hloov pauv, thiab cov txheej txheem tiv thaiv xeb yuav tsum tsim rau cov chaw muaj ntsev tsuag.

Lub neej tsim qauv> 20 xyoo, kev txij nkawm ≥5 xyoos.

2. Cov khoom siv hluav taws xob / dej kub:

Cov cylindrical roller bearings dais radial loads ntawm ntau pua tons thiab siv ua ke nrog lub tshuab cua txias sab nraud los tswj qhov kub nce.

Cov qib hlau tshwj xeeb (xws li M50 hlau) raug xaiv rau cov cheeb tsam kub siab.
