Mabili a koloi, li-gear tsa phetiso, li-spindle tsa lisebelisoa tsa mochini.

• boholo ba arge (joalo ka 30310):

Mechini ea kaho (lebili la pina la ho epa), mosi o moholo oa crusher ea morafo, phapang ea literaka tse boima ‌.

3. Li-bearings tsa roller tsa cylindrical (letoto la NN/NU)

• NN3020K (kholomo e habeli):

Spindle ea sesebelisoa sa mochini, rotor ea enjene e lebelo le phahameng, molala oa leloala o phutholohang ka nepo.

• Letoto la HONA JOALE:

Tšehetso e kholo ea stator ea enjene, lebokose la axle ea transit ea terene ‌.

Melao ea motheo ea kabo ea indasteri:

1. Indasteri ea likoloi ‌ (e ikarabellang bakeng sa 43%)

Li-bearing tsa Hub (li-bearing tse nang le li-roller tse tapered), li-bearing tsa jenereithara (li-bearing tsa bolo tse tebileng), li-bearing tsa gearbox (li-bearing tsa bolo tse hokahaneng le angular)

2. Matla le indasteri e boima

Mosi o ka sehloohong oa turbine ea moea (li-roller bearings tse ikamahanyang), yuniti ea matla a mocheso (li-roller bearings tsa cylindrical)

3. Lisebelisoa tse phahameng

Shaft e kholo ea enjene ea sefofane (li-bearing tsa bolo ea ceramic), lebokose la gear la terene le lebelo le phahameng (li-bearing tsa ho nepahala ha lebelo le phahameng).

Keletso ea khetho: Li-bearing tsa mohlala o tšoanang li ka sebelisoa maemong a fapaneng ka lebaka la limaraka tsa tsona tsa ho nepahala (P5/P4). Mohlala, li-spindle tsa lisebelisoa tsa mochini li hloka li-bearing tse nepahetseng tsa sehlopha sa P4 kapa ho feta ‌. Li-bearing tsa matla a moea li hloka moralo o khethehileng oa ho thibela ho bola le bophelo ba tšebeletso ‌. Bakeng sa liparamente tse itseng tsa mohlala, ka kopo sheba bukana ea botekgeniki ea moetsi.

Litlhoko tsa mantlha tsa ts'ebetso ea ho jara li fapana haholo liindastering tse fapaneng, haholo-holo li shebane le litekanyo tse kang ho nepahala, lebelo la ho potoloha, bokhoni ba mojaro le ho ikamahanya le tikoloho.

Indasteri ea likoloi

1. Li-bearing tse ncha tsa enjene tse khannang eneji: Li hlokahala hore li be le lebelo le phahameng ka ho fetisisa (boleng ba dm•n ≥ 70,000 mm·r/min), khanyetso ea mocheso o phahameng (> 150℃), le khanyetso ea ho thothomela ha maqhubu a phahameng. Thepa e hloka ho ba le botsitso bo phahameng, 'me sistimi ea ho tlotsa e hloka ho ikamahanya le maemo a rarahaneng a ts'ebetso ea enjene.

1. Li-bearing tsa enjene tsa setso: Li-bearing tsa pulley ea tensioner le li-bearing tsa pulley ea idler li hloka ho ba le botsitso bo phahameng le lerata le tlase ho fihlela litlhoko tse sebetsang hantle tsa phetiso tlas'a mokhoa oa paballo ea matla a enjene.

3. Ho bea Hub: Li-bearings tse nang le li-roller tse tenyetsehang li hloka ho mamella meroalo e nang le tšusumetso e habeli ha li ntse li fihlela litlhoko tsa moralo o bobebe le o tšoarellang nako e telele (joalo ka lik'hilomithara tse fetang milione e le 'ngoe).

Sefofane

1. Moeli oa ho nepahala: Mamello ea li-bearing tsa enjene ea aero e hloka ho ba ≤0.005 millimeters (5 microns), 'me mehlala ea sesole e bile e hloka ho nepahala ha 0.1 microns ‌.

2. Mamello e feteletseng ea tikoloho:

• Li-bearing tsa sebaka li lokela ho hanela mocheso o phahameng le o tlase (-180℃ ho isa ho 300℃), mahlaseli a kotsi le ho ba le ho fetoha ha khase ho tlase.
• Rarolla bothata ba ho tlotsa ka vacuum ka ho sebelisa thepa ea letsopa kapa li-lubricant tsa perfluoropolyether (PFPE).

3. Tšepahala: Monyetla oa ho hloleha 20,000 rpm).

Matla le Indasteri e Boima

1. Tšepe e kholo ea turbine ea moea:

Li-roller bearings tse ikamahanyang li hloka ho mamella ho feto-fetoha ho matla ha mojaro oa moea le linako tsa ho kheloha, 'me seaparo se thibelang ho bola se lokela ho etsoa bakeng sa libaka tsa ho fafatsa letsoai.

Bophelo ba moralo > lilemo tse 20, potoloho ea tlhokomelo ≥ lilemo tse 5 ‌.

2. Lisebelisoa tsa motlakase oa mocheso/metsi:

Li-bearings tsa cylindrical roller li jara meroalo ea radial ea lithane tse makholo 'me li sebelisoa hammoho le sistimi ea ho pholisa ea kantle ho laola ho phahama ha mocheso.

Mekhahlelo e khethehileng ea tšepe (joalo ka tšepe ea M50) e khethoa bakeng sa libaka tse nang le mocheso o phahameng.
