Moralo oa mohopolo oa ho jara enjene ea Aero

Lienjene tsa lifofane ke pelo ea lifofane, 'me ts'ebetso ea tsona, polokeho le ts'epo li khetholla ka kotloloho ts'ebetso, bophelo le ts'epo ea lifofane, 'me ts'ebetso ea ho jara ke e 'ngoe ea lintlha tsa bohlokoa tse amang bophelo le ts'epo ea lienjene tsa lifofane.

 

Enjene ea lifofaneli-beringli na le maemo a thata a ho sebetsa, haholo-holo li-bearing tsa spindle, tse hlokang ho fihlela litlhoko tsa mocheso o phahameng, lebelo le phahameng, ts'ebetso e tsitsitseng (e loketseng meroalo e bobebe, meroalo e boima, ho potlakisa le ho fokotsa lebelo ka potlako, meroalo ea ho tšoha, meroalo ea ho thothomela, jj.), ho tšepahala ho hoholo le bophelo bo bolelele. Hona joale, ho entsoe lipatlisiso tse ngata mabapi le li-bearing tsa enjene ea aero, mofuta oa li-bearing tse kholo le moralo oa li-parameter tse kholo, mokhoa oa ho tlotsa le sebopeho sa ho flanging, sebopeho sa pokotho, sekhutlo sa gasket, theknoloji ea kalafo ea bokaholimo, mokhoa oa tšebeliso ea motsoako oa li-bearing, jj. li na le tšusumetso e kholo ts'ebetsong ea tsona, moralo o utloahalang o ka qoba ho hloleha ha pele ho nakoli-bering, ntlafatsa ts'ebetso ea eona ea ts'ebetso le ho atolosa bophelo ba eona ba ts'ebeletso. Pampiri ena e hlahisa ho hlaka ha li-bearing tsa enjene ea aero le ho rarolla lintlha tse susumetsang tse lokelang ho nahanoa ts'ebetsong ea moralo oa li-bearing.

Litšobotsi tse ikhethang tsa li-bearing tsa enjene ea aero

Likarolo tsa sebopeho:

Li-bearing tsa enjene ea Aero: ho latela karolo ea tšebeliso, e ka aroloa ka mekhahlelo e meraro: li-bearing tsa spindle, li-bearing tsa gearbox tsa phetisetso ea lisebelisoa le li-bearing tsa gearbox tse fokotsang.

1. Ho bea spindle

Li-spindle bearing li tšehetsa li-rotor tsa fene tsa enjene, li-rotor tsa jenereithara ea khase le li-rotor tsa turbine ea matla, hangata li sebelisa motsoako oa li-bearing tsa li-angle tse nang le lintlha tse tharo tsa li-angle le li-roller bearing tsa cylindrical, li-angle tse nang le lintlha tse tharo tsa li-angle tse nang le li-angle tse nang le li-angle tse nang le li-axial moroalo le moroalo oa radial oa rotor, li-roller bearing tsa cylindrical li jara moroalo oa radial feela, 'me litšobotsi tsa ts'ebetso tsa li-spindle bearing ke lebelo le phahameng la ho potoloha (boleng ba dn ho fihlela ho 2.6 × 106 mm · r/min), mocheso o phahameng (180 ~ 250 °C, nako e khuts'oane e kholo ho feta 300 °C), moroalo o moholo oa axial, moroalo o bobebe oa nako e khuts'oane le ho jara ka bongata ka lehlakoreng la radial, tataiso ea phetoho ea moroalo oa axial le sebaka se kopaneng sa ho kenya. Ka hona, li-spindle bearing li na le maemo a phahameng a mamello, ka kakaretso a seng tlase ho boemo ba P4, 'me hape li na le litlhoko tse tiileng bakeng sa ho nepahala ha machining ea li-roller tsa cylindrical; Ho phaella moo, li-spindle bearing li tlotsoa haholo tlas'a lesale, e leng se hlokang moralo o khethehileng o tsamaellanang.

 

2 Lebokose la gear la phetiso ea lisebelisoa

 

Boreleli ba lebokose la phetiso ea khokahano bo tšehetsa rotor ea gear ea sistimi ea phetiso ea lisebelisoa, 'me litšobotsi tsa eona tsa ts'ebetso ke mojaro o monyane, mocheso o tlase (120 ~ 150 °C), le lebelo le tlase la ho potoloha (boleng ba dn ha bo holimo ho 1.5 × 106 mm · r/min）。

 

3 Lebokose la lebokose la ho fokotsa

 

Kopano ea li-gear tsa li-reducer bearing reducer, litšobotsi tsa eona tsa ho sebetsa ke mojaro o moholo, lebelo le tlase le mocheso o tlase (120 ~ 150 °C).

 

Litlhoko tse akaretsang

Ka lebaka la ho ikhetha ha tikoloho ea ts'ebeliso le maemo a ts'ebetso a lienjene tsa aero, litlhoko tse akaretsang tsa li-bearing li thata ho feta tsa li-bearing tse tloaelehileng, 'me litlhoko tse amehang ke tse latelang.

 

1. E hanela mocheso o phahameng ha e paka

 

Ha enjene e sebetsa, moea o batang o kenngoa ho pholisa mahare, li-bearing le likarolo tse ling, 'me li-bearing le tsona li pholisoa ka oli e tlotsang. Leha ho le joalo, kamora ho koaloa, mehato ena ea ho pholisa ha e sebetse, 'me mocheso oa turbine o tla fetisetsoa ho bearing ka ntlo ea bearing le shaft, e leng se fellang ka ho phahama ka potlako ha mocheso oa bearing ka nako e khuts'oane, haholo-holo mocheso oa bearing oa enjene e chesang o tla nyoloha ka mokhoa o sa tloaelehang, 'me lintlha tse ling tsa tlhahlobo ea enjene li bontša hore mocheso oa bearing o tla fihla ho hoo e ka bang 350 °C.

 

2. Ho tlotsa oli ka ho e tlotsa ho matha ha bokgoni

 

Maemo a phepelo ea oli ea ho tlotsa ea li-bearing tsa enjene ea aero a arotsoe haholo-holo ka mekhahlelo e 'meli:

1) Pele enjene e qala ho sebetsa ka mokhoa o tloaelehileng oa sistimi ea oli e tlotsang, e ba boemong ba ho bata, ka lebelo le tlase le mojaro o monyane;

2) Ha enjene e sebetsa, haeba sistimi ea oli e tlotsang e sa khone ho tsoela pele ho fana ka oli ka mabaka a ikhethang, 'me enjene e hloka ho tsoela pele ho sebetsa ka nako e itseng, bearing e tla ba boemong ba ho tlotsa oli hampe kapa esita le ts'ebetso e omileng, 'me e ke ke ea tlotsoa hantle le ho pholisoa. Ho netefatsa polokeho ea sefofane, li-bearing li hloka ho ba le bokhoni ba ho tsoela pele ho sebetsa ka tloaelo ka nako e itseng ntle le ho hloleha ntle le ho tlotsa oli.

 

3 Mosebetsi o motle

 

Enjene ea lifofaneli-beringho hlokahala hore ho be le ts'ebetso e ntle, mosebetsi oa ho kopanya le litšobotsi tse bobebe. E le ho fokotsa bothata ba ho kopanya, lienjine tsa aero li hloka likarolo tse fokolang kamoo ho ka khonehang, 'me spindle hangata e hloka ho hlomelloa ka litšehetso tsa elastic sebakeng sa tšehetso ho lokisa lebelo la bohlokoa la rotor, 'me li-damper tsa filimi ea oli li behiloe ho thibela ho thothomela ha rotor, tseo ka bobeli li tla nka sebaka sa radial. E le ho boloka sebaka sa radial ho eketsa palo ea likarolo tse pitikoang le ho ntlafatsa bokhoni ba ho jara, lesale la kantle la ho jara hangata le kopanngoa le tšehetso ea elastic ea lesaka la squirrel le damper ea filimi ea oli. E le ho fokotsa palo ea likarolo le ho fokotsa bothata ba ho kopanya, tšehetso ea lesaka la squirrel, flange e hokeloang le groove ea lesale la ho damping filimi ea oli li kopanngoa le lesale la kantle la bearing, empa ho boetse ho na le mathata a kang bothata bo eketsehileng ba moralo, matla a fokolang a sebopeho, le khetho e thata ea thepa le ts'ebetso ea tlhahiso.

 

4 Sistimi e tsoetseng pele ea netefatso ea boleng

 

Ntle le mehopolo e tsoetseng pele ea moralo le ho nepahala ho phahameng ha ts'ebetso, ho boetse hoa hlokahala ho itšetleha ka sistimi e tsoetseng pele ea netefatso ea boleng ho kenyeletsoa maemo a ts'ebetso, lisebelisoa tsa ts'ebetso, tlhahlobo ea boleng, basebetsi, netefatso ea liteko, setifikeiti sa boleng le likarolo tse ling.
