Ibyuma bya moteri by'indege

Igipimo cy'imodokaubwoko

Umuvuduko wa moteri y'ikirere ni mwinshi, ubushyuhe bushyuha ni bwinshi, kandiikirangoikeneye gutwara umutwaro w'umurongo n'umutwaro w'imirasire, bityo ubwikorezi bugabanyijemo ibice bibiri: ubwikorezi bw'umurongo w'umurongo w'umurongo n'ubwikorezi bw'umurongo w ...imiringa y'imizingo izungurukanta mipaka iri ku mpande zo hanze cyangwa imbere zikunze gukoreshwa.

 

Udusanduku tw’amashanyarazi two mu bwoko bwa Aero dukunze gukoreshwa na za verisiyo za spur, kandi za verisiyo zitwara gusa imitwaro ya radial kandi kwaguka k’ubushyuhe bwa rotor ni gato, bityoimiringa y'imizingo izungurukanaimipira y'umupira w'uburebure buniniahanini batoranywa.

 

Agasanduku k'amashanyarazi gatuma ingufu zigabanuka gatanga ingufu nyinshi, zimwe muri zo zikoresha ibyuma bizunguruka, kandi ibyuma bitanga ingufu bigomba gutwara imizigo ya radial na axial, bityoimiringa y'imizingo izunguruka, imipira y'umupira w'uburebure buninin'amanota atatuimipira yo gufatanyaho inguniahanini batoranywa.

 

Moteri z'indege zikoresha ibyuma bipima imiterere y'umupira bifite imiterere itatu kandiimiringa y'imizingo izunguruka.

Ibyuma by'umupira bifite impande eshatu

Iyo moteri y'ikirere ikora, umutwaro wa radial n'umutwaro wa axial bizakorwa kuri spindle, kandi muri rusange hashyirwaho imigozi y'umupira ku gice cy'imbere cy'spindle kugira ngo itware umutwaro wa radial ukozwe no gushyiramo imbaraga zidahuje za buri shaft n'umuvuduko mwinshi, kandi icyarimwe ikagira itandukaniro hagati y'umutwaro wa axial uri hagati y'imbaraga za pneumatic z'umufana na compressor imbere n'imbaraga za pneumatic inyuma ya turbine.

 

Ugereranije imiterere y'imirongo y'umupira w'igorofa yimbitse n'imirongo y'umupira w'igorofa ifite ingingo eshatu, hagati y'umuyoboro w'imbere w'umuyoboro w'umupira w'igorofa ufite ingingo eshatu ufite Lo, ituma aho uhagarara Ga n'ingano ya rotor mu cyerekezo cy'umuyoboro bigabanuka kandi byoroshye kugenzura aho uhagarara wa stove izenguruka ya moteri.

 

Umupira w’impande eshatu ufite imiterere y’impeta y’imbere ifite igice cy’imbere gifite imiterere ibiri, kandi imiterere yawo y’impeta y’imbere ishobora gutandukana yemerera gushyirwaho imipira myinshi, bikongera cyane ubushobozi bwo gutwara.

 

Ugereranije imiterere y'imigozi y'umupira w'amapine n'imigozi y'umupira w'amapine ifite impande eshatu, imigozi y'umupira w'amapine ishobora gutwara imizigo y'inzira imwe gusa, niba ikeneye gutwara imizigo y'amapine ifite impande ebyiri, igomba guhuzwa, bizatwara umwanya munini kandi bikongere uburemere; Impeta ebyiri n'igice z'imbere z'imigozi y'umupira w'amapine ifite impande eshatu zishobora gutwara imizigo y'amapine ifite impande ebyiri, ishobora kuzigama hafi 50% by'umwanya n'ubwiza ugereranije n'imigozi ibiri cyangwa itsinda ry'imigozi y'umupira w'amapine ifite impande ebyiri, kandi biroroshye gushyiraho, byoroshye gushushanya moteri.

 

Inzu n'imipira byo guteranya umupira w'impande eshatu bishobora gutandukanywa n'impeta y'inyuma, bityo hashobora gukoreshwa inzu imwe ikomeye, ifite imbaraga nyinshi, ikwiriye umuvuduko mwinshi wo kuzenguruka, kandi byoroshye kubona ubuhanga bwo gukora neza; Muri icyo gihe, imiterere inatuma gushyiraho no kugenzura ibyuma byoroshye.

 

Ibyuma bizunguruka by'uruziga

Ugereranyije n'udupira tw'imizingo dusanzwe twa mekanike, umurambararo w'udupira tw'imizingo duto twa moteri ya aero ni muto, kandi ibyiza byatwo ni ibi bikurikira:

1) Ishobora kugabanya imbaraga zo gukurura amavuta mu gihe cyo gukora vuba cyane;

2) Imbaraga zidafite imbaraga ni ntoya;

3) Umuvuduko uhagije wo gukoraho ushobora kugumaho iyo imbaraga za radial ari nto kugira ngo hirindwe kunyerera kw'imizingo;

4) Kubera ko ibice bya ferrule, rollers na cage bishobora gutandukanywa, hashobora gukoreshwa cage ikomeye, ifite imbaraga nziza kandi ihamye cyane.

 

Ibyuma bizunguruka by'uruzigaIyo impeta y'imbere idafite flange, ubusanzwe ifite ubugari bunini bw'impeta y'imbere kugira ngo ijyane n'ingendo hagati y'impeta z'imbere n'iz'inyuma bitewe n'uburebure buterwa no kwaguka k'ubushyuhe hagati y'umugozi n'impeta y'imbere y'icyuma gifata icyuma, ndetse no kutagera ku murongo hagati y'impeta z'imbere n'iz'inyuma bitewe n'ikosa ryo guteranya icyuma gifata icyuma mu gihe cyo guteranya. Iyo umwanya wo gushyiraho ari muto cyangwa hari ibisabwa byihariye, icyuma cyangwa icyuma gifata icyuma gishobora gukoreshwa mu buryo butaziguye aho gukoresha icyuma gifata icyuma kidafite flange.

 

Moteri y'indegeimiringa y'imizingo izungurukaakenshi bahura n'imimerere y'akazi k'umutwaro muto cyangwa nta mutwaro n'umwe wa radial, kandi umuvuduko wo kuzenguruka uri hejuru cyane, imigozi ikunze kunyerera no gukurura, kugira ngo hirindwe kunyerera, inzira z'imihanda idakikije zikunze gukoreshwa kugira ngo harebwe umutwaro wa radial mbere y'umutwaro, kandi imitwaro y'imihanda ibiri isanzwe idakikije ikunze gukoreshwa.

 

Ibikoresho byo gutwara ibintu

Ubushyuhe bw'aho turbine ya moteri ikorera ni bwinshi cyane, kandi akenshi ni ngombwa gukonjesha turbine ukoresheje amavuta yo kwisiga ya litiro nyinshi ku munota, ariko ubushyuhe bw'aho turbine ikorera bushobora kugera kuri dogere selisiyusi 250.

 

Kugira ngo ihuze n'imiterere y'akazi k'ubushyuhe bwinshi, impeta yo guterura ikoresha icyuma cya 8Cr4Mo4V (M50) n'ibindi byuma bipima ubushyuhe bwinshi, kandi ivurwa n'ubushyuhe bwinshi, nubwo ubushyuhe bwo guterura bwagera kuri 400 °C nyuma yuko moteri ihagaritswe, iracyashobora kwemeza imikorere y'icyuma. Kugira ngo ihuze n'igihe cyo kurambirwa, ubukana bw'ubuso bw'igikoresho cyo guterura busabwa muri rusange kuba nibura 60 HRC ku bushyuhe bw'icyumba, kandi icyuma cya 8Cr4Mo4V cyose gikomera bitewe n'ubushyuhe, ariko ubukana buri hasi ugereranyije n'ubw'ibikoresho by'imiterere, bizatuma icyuma gicika iyo imbaraga za feri zigana hejuru n'umuvuduko w'umugozi ari munini. Kubwibyo, agaciro ka dn karenze 2.5 × 106 mm · r/min bearing zigomba gukorwa mu bikoresho bya G13Cr4Mo4Ni4V (M50NiL), bifite ubukana bwiza bw'imbere.

 

Ibikoresho bya cage bya moteri ya aero muri rusange bikozwe mu byuma by'ubwubatsi nka 40CrNiMoA (4030), kandi cage igomba gushyirwaho silver-plated kugira ngo igabanye kwangirika mu gihe cyo gutangira. Ikintu cyo kuzingurura ni kimwe n'ibikoresho bya ferrule, kandi ubukana bwacyo muri rusange ni kimwe n'ubw'icyuma cya ferrule, kandi rimwe na rimwe kizaba kiri hejuru ya 1 ~ 2 HRC kurusha ferrule. Hari igihe umupira ukoresha ibikoresho bya ceramic nka silicon nitride, alumina, na zirconia.
