Yintoni iBearing yoBushushu obuphantsi

I-bearing enobushushu obuphantsi ayibhekiseli kwi-bearing esebenza ngokuzinzileyo kwiindawo ezinobushushu obuphezulu (ngokuchaseneyoiibheringi zobushushu obuphezulu), kodwa endaweni yoko yibheringi eyilwe ngezinto ezikhethekileyo kunye noyilo lwesakhiwo ukunciphisa i-frictional coefficient, ngaloo ndlela kunciphisa ubushushu bokungqubana. Oku kuvumela ibheringi ukuba igcine ubushushu obuphantsi nokuba isebenza ixesha elide.

 

IibheringiEzinobushushu obusebenzayo obungaphantsi kwe -60℃ zithathwa njengeebheringi zobushushu obuphantsi. Zisetyenziswa kakhulu kwiimpompo ezahlukeneyo zolwelo, ezifana neempompo zegesi yendalo ezinyibilikisiweyo, iimpompo ze-nitrogen (hydrogen, oxygen), iimpompo ze-butane, iimpompo zolwelo zeerokethi kunye neemissile, ii-spacecraft, njalo njalo.

 

Ubushushu bokusebenza beebheringi zobushushu obuphantsi

Ubushushu bokusebenza kwebheriya enobushushu obuphantsi bubonakalisa iteknoloji yezinto kunye nenqanaba lokwenziwa kwebheriya. Ngokuyintloko ilinganiswa ngumahluko wobushushu phakathi kweringi yangaphandle yebheriya kunye neoyile yokupholisa efakwe ngexesha lokusebenza. Ubushushu obuphantsi bokusebenza buthetha ubomi obude bebheriya kunye nokusebenza okuphezulu.

 

Iindidi zeebheringi zobushushu obuphantsi

Iibheringi eziphantsi kobushushu zihlala ziibheringi zebhola ezinzulu zomqolo omnye kunye neebheringi zerola ezisilinda.

 

NgokubaiibheringiUkuba ifumana ukuxhuzula kumaqondo obushushu aphantsi, into yangaphandle kukutshintsha kobushushu, ngelixa into yangaphakathi ingama-coefficients ahlukeneyo okwandisa ubushushu kwi-shaft, isakhelo, kunye nezinto. Xa uluhlu lobushushu lukhulu, izinto ezahlukeneyo ziyancipha ngamanani ahlukeneyo, nto leyo enciphisa ukususwa kwento kwaye ibangele ukuxinana. Ke ngoko, kwizixhobo ezinoluhlu olubanzi lokusebenza, kuquka nezixhobo ezisetyenziswa kumaqondo obushushu aphantsi, kuyimfuneko ukubala ama-coefficients okwandisa izinto kwaye, apho kunokwenzeka, kusetyenziswe izinto ezine-coefficients efanayo yokwandisa ukuze ufumane iziphumo ezingcono.

 

Ukongeza, kuyilo lwesakhiwo, kuyacetyiswa ukuba kuphetshwe ukusebenzisa i-roller bearing ekhonkrithi kwicala ngalinye le-shaft. Kwisakhiwo esinjalo, okukhona umgama omde phakathi kwee-bearing ezimbini, kokukhona amathuba okuxinana aphezulu. Ukuba kufakwe ii-bearing ezimbini ezinciphileyo kwelinye icala le-shaft, zingasebenza njengendawo yokubeka i-shaft, zithintele intshukumo ye-axial. Elinye icala le-shaft, elisetyenziswa ne-rolling bearing, lithintela kuphela amandla e-radial, livumela intshukumo ye-axial elinganiselweyo kunye notshintsho lobushushu be-axial.

 

Ukukhethwa kwezinto zeebheringi zobushushu obuphantsi

Ukukhethwa kweNtsimbi yoBearing yeeBearing eziphantsi kobushushu

Iibheringi ezisebenzisa ubushushu obuphantsi zihlala zenziwe ngeentsimbi ze-stainless bearing 9Cr18 okanye 9Cr18Mo, kwaye zinokwenziwa nge-beryllium bronze, iiceramics, kunye nezinye izinto. Phantsi kwamaqondo obushushu aphantsi kakhulu okusebenza (amaqondo obushushu aphezulu -253℃), ukuba umda wokusebenza ufuna -253℃, izinto ze-6Cr14Mo zingakhethwa kodwa kufuneka zisetyenziswe kwindawo engenamoya.

 

Ngexesha lokusetyenziswa kweebheringi ezinobushushu obuphantsi, kufuneka kuqwalaselwe imiba efana nokushisa kakhulu okubangelwa kukuthambisa okungekho semgangathweni, ngoko ke kubalulekile ukukhetha iigrisi ezifanelekileyo.
