Mabheyaringi einjini dzemhepo

Kutakuramhando

Kumhanya kweinjini yeaero spindle kwakakwira, tembiricha inopisa yakakwira, uyekuberekainoda kutakura mutoro weaxial uye mutoro weradial, saka bearing yakakamurwa kuita mapoka maviri: thrust fulcrum bearing uye swimming fulcrum bearing: thrust fulcrum bearing inowanzo shandisa three-point angular contact ball bearing kutakura mutoro weaxial uye kudzora axial clearance ye rotating stator; Traveling fulcrum bearings inongotakura mutoro weradial chete, uye nekuti rotor ichafamba munzira yeaxial nekuda kwekuwedzera kwekupisa uye kudzikira,mabheyaringi eroller ane cylindricalZvinowanzo shandiswa zvisina miganhu parin'i yekunze kana yemukati.

 

Mabhokisi egiya ekushandisa injini yeAero anowanzo fambiswa nemagiya espur, uye mabheyaringi anongotakura mitoro ye radial uye kuwedzera kwekushisa kwe rotor kudiki, sakamabheyaringi eroller ane cylindricaluyemabheyaringi ebhora akadzikazvinonyanya kusarudzwa.

 

Giya remagetsi rinoburitsa simba rakawanda, mamwe acho anoshandisa magiya ehelical, uye mabheyaringi anofanira kutakura mitoro ye radial ne axial, sakamabheyaringi eroller ane cylindrical, mabheyaringi ebhora akadzikauye mapoinzi matatumabheyaringi ebhora rekubatana nekonazvinonyanya kusarudzwa.

 

Injini dzemumhepo dzinoshandisa mabheyaringi ebhora ane makona matatu uyemabheyaringi eroller ane cylindrical.

Mabheyaringi ebhora ane makona matatu

Kana injini yeaero ichishanda, radial load uye axial load zvichagadzirwa pa spindle, uye seti yemabhora bearing anowanzoiswa panzvimbo ye fulcrum pamberi pe spindle kuti atakure radial load inoumbwa ne superposition ye unbalanced force ye shaft yega yega uye high-speed rotation, uye panguva imwe chete inotakura musiyano we axial load pakati pe pneumatic force ye fan ne compressor mberi uye pneumatic force kumashure kwe turbine.

 

Kuenzanisa chimiro chemabheyaringi ebhora akadzika uye mabheyaringi ebhora ane mativi matatu, pakati pemugero wemukati webheyaringi rebhora rine mativi matatu rine mativi matatu rine axial eccentricity Lo, izvo zvinoita kuti axial clearance yayo Ga uye huwandu hwerotor mudivi re axial zvive nyore uye zvishoma kudzora axial clearance yechitofu chinotenderera cheinjini.

 

Bearing yebhora remakona matatu ine chimiro chering ine hafu yepakati kaviri, uye dhizaini yayo inopatsanurwa nering ine hafu yepakati inobvumira kuiswa kwemabhora akawanda, zvichiwedzera zvakanyanya kugona kwebearing.

 

Kuenzanisa chimiro chemabheyaringi emabhora ekubatana e-angular nemabheyaringi emabhora ekubatana e-three-point angular, mabheyaringi emabhora ekubatana e-angular anogona kutakura mitoro ye-axial yenzira imwe chete, kana achida kutakura mitoro ye-axial ye-bidirectional, anofanira kubatanidzwa, izvo zvinotora nzvimbo yakawanda uye kuwedzera huremu; Mhete mbiri nehafu dzemukati dzemabheyaringi emabhora ekubatana e-three-point angular dzinogona kutakura zvakananga mitoro ye-axial ye-bidirectional, izvo zvinogona kuchengetedza nzvimbo nehukuru hwe50% zvichienzaniswa nemutsara wakapetwa kaviri kana boka remabheyaringi emabhora ekubatana e-angular anotsigira, uye zviri nyore kuisa, izvo zviri nyore kugadzira injini.

 

Keji nebhora zvinosangana zvebhora remakona matatu zvinogona kuparadzaniswa neringi rekunze, saka keji yakasimba ine chidimbu chimwe chete inogona kushandiswa, ine simba rakawanda, yakakodzera kumhanya kwakanyanya, uye iri nyore kuwana kunyatsogadzirwa kwemashini; Panguva imwe chete, chimiro ichi chinoitawo kuti kuiswa nekuongororwa kwemabheringi kuve nyore.

 

Mabheyaringi ecylindrical roller

Zvichienzaniswa nemabheyaringi esimbi esimbi esimbi, dhayamita yesimbi yesimbi yesimbi yesimbi yesimbi yesimbi idiki, uye zvakanakira zvayo ndeizvi:

1) Inogona kuderedza kuramba kwemuchina wekukwesha mafuta panguva yekushanda nekukurumidza;

2) Simba rekusashanda kwesimba diki;

3) Kumanikidzwa kwakakwana kwekusangana kunogona kuchengetedzwa kana simba re radial riri diki kudzivirira kutsvedza kwe roller;

4) Sezvo zvikamu zveferrule, roller uye keji zvichigona kupatsanurwa, keji yakasimba inogona kushandiswa, ine simba riri nani uye kugadzikana nekukurumidza.

 

Mabheyaringi ecylindrical rollerPasina flange mumhete yemukati inowanzova nehupamhi hwakakura hwemhete yemukati kuti igone kufamba kweaxial pakati pemhete dzemukati nedzekunze kunokonzerwa nekureba kunokonzerwa nekuwedzera kwekupisa pakati peshaft nemhete yemukati yebearing, pamwe nekusarongeka pakati pemhete dzemukati nedzekunze kunokonzerwa nekukanganisa kweaxial assembly yerotor assembly panguva yekuunganidza. Kana nzvimbo yekuisa iri diki kana paine zvinodiwa zvakakosha, shaft kana bearing housing inogona kushandiswa zvakananga panzvimbo yemhete yemukati isina flange.

 

Injini yemhepomabheyaringi eroller ane cylindricalKazhinji vanosangana nemamiriro ekushanda emutoro mudiki kana usina radial, uye kumhanya kwekutenderera kwakanyanya, maroller anowanzo kutsvedza uye kukwesha, kuitira kudzivirira kutsvedza, nzira dzemujaho dzisina kutenderera dzinowanzo shandiswa kuita kuti radial preload yebearing isvike, uye kugoverwa kwemutoro kwemabearing maviri emujaho asina kutenderera kunowanzo shandiswa.

 

Zvinhu zvinotakura

Tembiricha yekushanda kwebearing yeinjini yakakwira zvikuru, uye zvinowanzodiwa kutonhodza bearing nemafuta ekuzora emarita akati wandei paminiti, asi tembiricha yekushanda yebearing inogona kusvika pa250 °C.

 

Kuti ishande mumamiriro ekushanda ane tembiricha yepamusoro, mhete yebearing inowanzo shandisa simbi ye8Cr4Mo4V (M50) nedzimwe simbi dzinopisa zvakanyanya, uye inobatwa nekupisa kwakanyanya, kunyangwe tembiricha yebearing ikasvika 400 °C mushure mekunge injini yamiswa, inogona kuramba ichiita kuti bearing ishande zvakanaka. Kuti ishande kwenguva refu, kuomarara kwechinhu chinobatirira kunowanzo fanirwa kunge kuri pasi pe60 HRC patembiricha yemumba, uye simbi ye8Cr4Mo4V yese inoomeswa nekupisa, asi kuomarara kwacho kwakaderera pane kwechinhu chinobatirira, izvo zvinozoita kuti ferrule ipwanyike kana simba re centrifugal re ferrule uye kushushikana kwe circumferential kwe shaft zvakakura. Nokudaro, dn value inodarika 2.5×106 mm · r/min bearing inofanira kugadzirwa nezvinhu zveG13Cr4Mo4Ni4V (M50NiL), zvine kusimba kuri nani kwepakati.

 

Zvinhu zvekeji zvemabheringi einjini aero zvinowanzogadzirwa nesimbi yekuvaka yakaita se40CrNiMoA (4030), uye keji yacho inofanira kuputirwa nesirivha kuti ideredze kusakara panguva yekutanga. Chinhu chinotenderedza chakafanana nezvinhu zveferrule, uye kuoma kwayo kwakafanana nekweferrule, uye mune dzimwe nguva inenge yakakwira ne1 ~ 2 HRC kupfuura ferrule. Dzimwe nguva bhora rinoshandisawo zvinhu zveceramic zvakaita sesilicon nitride, alumina, uye zirconia.
