Umklamo womqondo wokuthwala injini ye-Aero

Izinjini zezindiza ziyinhliziyo yezindiza, futhi ukusebenza kwazo, ukuphepha kanye nokuthembeka kunquma ngqo ukusebenza, impilo kanye nokuthembeka kwezindiza, kanye nokusebenza kokuthwala kungenye yezinto ezibalulekile ezithinta impilo kanye nokuthembeka kwezinjini zezindiza.

 

Injini ye-Aeroamabheringianezimo zokusebenza ezinzima, ikakhulukazi ama-spindle bearings, adinga ukuhlangabezana nezidingo zokushisa okuphezulu, isivinini esiphezulu, ukusebenza okuzinzile (okufanele imithwalo elula, imithwalo esindayo, ukusheshisa okusheshayo kanye nokwehla kwesivinini, imithwalo yokushaqeka, imithwalo yokudlidliza, njll.), ukuthembeka okuphezulu kanye nokuphila isikhathi eside. Njengamanje, kwenziwe ucwaningo oluningi kuma-bearings enjini ye-aero, uhlobo lwe-bearings oluyinhloko kanye nomklamo wamapharamitha ayinhloko, indlela yokugcoba kanye nesakhiwo se-flanging, isakhiwo sephakethe, i-engeli ye-gasket, ubuchwepheshe bokwelashwa kwendawo, indlela yokusebenzisa inhlanganisela yama-bearings, njll. kunomthelela omkhulu ekusebenzeni kwawo, ukwakheka okunengqondo kungagwema ukwehluleka kwasekuqaleni kweamabheringi, ithuthukise ukusebenza kwayo futhi yandise impilo yayo yesevisi. Leli phepha lethula ukucaciswa kwama-bearings enjini ye-aero futhi lihlunga izici ezithonya okufanele zicatshangelwe enkambisweni yokuklama ama-bearings.

Izici ze-bearings zenjini ye-aero

Izici zesakhiwo:

Ama-bearings enjini ye-Aero: ngokwengxenye yokusetshenziswa, angahlukaniswa ngezigaba ezintathu: ama-spindle bearings, ama-accessory gearbox bearings kanye nama-reducer gearbox bearings.

1. Ukuthwala kwe-Spindle

Ama-spindle bearings asekela ama-rotor fan enjini, ama-rotor ejeneretha yegesi kanye nama-rotor e-turbine yamandla, ngokuvamile asebenzisa inhlanganisela yama-three-point angular contact ball bearings kanye nama-cylindrical roller bearings, ama-three-point angular contact ball bearings athwala umthwalo we-axial kanye nomthwalo we-radial we-rotor, ama-cylindrical roller bearings athwala imithwalo ye-radial kuphela, futhi izici zokusebenza zama-spindle bearings yisivinini sokujikeleza esiphezulu (inani le-dn elifika ku-2.6 × 106 mm · r/min), izinga lokushisa eliphezulu (180 ~ 250 °C, isikhathi esifushane esingaphezu kuka-300 °C), umthwalo omkhulu we-axial, umthwalo wokukhanya wesikhashana kanye nokulayisha ngokweqile ohlangothini lwe-radial, isiqondiso sokushintsha umthwalo we-axial kanye nendawo yokufaka encane. Ngakho-ke, ama-spindle bearings anamazinga aphezulu okubekezelela, ngokuvamile angaphansi kwezinga le-P4, futhi anezidingo eziqinile zokunemba komshini wama-cylindrical rollers; Ngaphezu kwalokho, ama-spindle bearings agcotshwa kakhulu ngaphansi kwendandatho, okudinga umklamo okhethekile ohambisanayo.

 

2 Ibhokisi legiya lokudlulisa elisebenzisekayo

 

I-bearing yebhokisi legiya lokunamathisela isekela i-gear rotor yesistimu yokudlulisa eyisesekeli, futhi izici zayo zokusebenza umthwalo omncane, izinga lokushisa eliphansi (120 ~ 150 °C), kanye nesivinini sokujikeleza esiphansi (inani le-dn aliphakeme kune-1.5×106 mm · r/min（。

 

3 Ukuthwala ibhokisi legiya elinciphisayo

 

Ukuhlanganiswa kwegiya lokunciphisa elisekela ama-gearbox e-Reducer bearing, izici zalo zokusebenza umthwalo omkhulu, isivinini esiphansi kanye nokushisa okuphansi (120 ~ 150 °C).

 

Izidingo ezijwayelekile

Ngenxa yokubaluleka kwendawo yokusetshenziswa kanye nezimo zokusebenza zezinjini ze-aero, izidingo ezijwayelekile zama-bearings ziqinile kakhulu kunezo zama-bearings avamile, futhi izidingo ezifanele zimi kanje.

 

1. Imelana nokushisa okuphezulu lapho upaka

 

Uma injini isebenza, umoya obandayo ufakwa ukuze upholise ama-blade, ama-bearings nezinye izingxenye, kanti ama-bearings nawo apholiswa ngowoyela wokugcoba. Kodwa-ke, ngemva kokuvala, lezi zindlela zokupholisa azisebenzi, futhi ukushisa kwe-turbine kuzodluliselwa ku-bearings nge-bearing housing kanye ne-shaft, okuholela ekukhuphukeni okusheshayo kwezinga lokushisa le-bearings esikhathini esifushane, ikakhulukazi izinga lokushisa le-bearing le-end eshisayo yenjini lizokhuphuka ngendlela engavamile, futhi idatha ethile yokuqapha injini ikhombisa ukuthi izinga lokushisa le-bearing lizofinyelela cishe ku-350 °C.

 

2. Umthamo wokusebenza wokuphazamiseka kokuphazamiseka kwamafutha okugcoba

 

Izimo zokuphakelwa kukawoyela wokugcoba kwama-bearings enjini ye-aero zihlukaniswe kakhulu ngezigaba ezimbili:

1) Ngaphambi kokuba injini iqale ukusebenza okujwayelekile kohlelo lwamafutha okugcoba, isuke isesimweni sokubanda sokusebenza, ngesivinini esiphansi kanye nomthwalo omncane;

2) Uma injini isebenza, uma uhlelo lwamafutha okugcoba lungakwazi ukuqhubeka nokuhlinzeka ngamafutha ngenxa yezizathu ezikhethekile, futhi injini idinga ukuqhubeka isebenza isikhathi esithile, i-bearing izoba sesimweni sokugcotshwa ngamafutha okungekuhle noma ngisho nokusebenza okomile, futhi ayikwazi ukugcotshwa kahle nokupholiswa. Ukuqinisekisa ukuphepha kokundiza, ama-bearing kudingeka abe nekhono lokuqhubeka nokusebenza ngokujwayelekile isikhathi esithile ngaphandle kokwehluleka ngaphandle kokugcoba ngamafutha.

 

3 Umsebenzi omuhle

 

Injini ye-Aeroamabheringikudingeka ukuthi kube nokucutshungulwa okuhle, ukwenziwa kahle kwe-assembly kanye nezici ezilula. Ukuze kuncishiswe ubunzima bokuhlanganisa, izinjini ze-aero zidinga izingxenye ezimbalwa ngangokunokwenzeka, futhi i-spindle ngokuvamile idinga ukuhlonyiswa ngezisekelo ze-elastic endaweni yokusekela ukuze kulungiswe ijubane elibalulekile le-rotor, futhi ama-damper efilimu kawoyela asethelwe ukucindezela ukudlidliza kwe-rotor, kokubili okuzothatha isikhala se-radial. Ukuze kongiwe isikhala se-radial ukuze kwandiswe inani lezinto ezigingqikayo futhi kuthuthukiswe umthamo wokuthwala, indandatho yangaphandle yokuthwala ivame ukuhlanganiswa nokusekelwa kwe-elastic kwekheji lika-squirrel kanye ne-damper yefilimu kawoyela. Ukuze kuncishiswe inani lezingxenye futhi kuncishiswe ubunzima bokuhlanganisa, ukwesekwa kwekheji lika-squirrel, i-mounting flange kanye ne-oil film damping ring groove kuhlanganiswe endandatho yangaphandle ye-bearing, kodwa kukhona nezinkinga ezifana nobunzima bokuklama obandayo, amandla ancishisiwe esakhiwo, kanye nokukhetha izinto eziqinile kanye nenqubo yokukhiqiza.

 

4 Uhlelo lokuqinisekisa ikhwalithi oluthuthukisiwe

 

Ngaphezu kwemibono yokuklama ethuthukisiwe kanye nokunemba okuphezulu kokucubungula, kuyadingeka futhi ukuthembela ohlelweni lokuqinisekisa ikhwalithi oluthuthukisiwe oluhlanganisa amazinga enqubo, imishini yokucubungula, ukuhlolwa kwekhwalithi, opharetha, ukuqinisekiswa kokuhlolwa, isitifiketi sekhwalithi nezinye izinto.
