Yintoni i-turbo bearing? Iintlobo zee-turbocharged bearing

Ukuthwala iTurboyintsimbi ekwi-turbocharger, ukuze siqonde i-turbocharger, okokuqala kufuneka sazi i-turbocharger kunye neendawo zayo ezihambayo.

 

Yeyiphi i-turbocharger?

I-turbocharger, esiyifumana rhoqo ezimotweni, yi-air compressor ecinezela umoya ukuze yonyuse ubungakanani bomoya othathwayo. Isebenzisa i-inertial impulse yegesi yokukhupha umoya ekhutshwa yinjini ukuze ityhale i-turbine kwigumbi le-turbine, kwaye i-turbine iqhuba i-coaxial impeller, kwaye i-impeller icinezela umoya othunyelwa ngumbhobho we-air filter ukuze uyicinezele kwi-cylinder. Xa isantya senjini sisanda, isantya sokukhupha igesi yokukhupha umoya kunye nesantya se-turbine nazo ziyanda ngokulandelelana, i-impeller icinezela umoya omninzi kwi-cylinder, uxinzelelo kunye nobuninzi bomoya bunokutshisa ipetroli engaphezulu, bonyuse inani lepetroli kwaye balungise isantya senjini, unganyusa amandla okukhupha enjini.

 

Zithini iindawo ezishukumayo ze-turbocharger?

Iindawo ezihambayo ze-turbocharger nazo ziyinxalenye ephambili - ivili le-turbine, i-compressor impeller kunye ne-rotor shaft, kunye ne-supercharger housing zinentshukumo ekhawulezayo, enganyamezelekiyo kwiibheringi eziqhelekileyo, ngoko ke i-bearing ye-supercharger yibheringi ekhethekileyo edadayo.

 

Ngokwenene yiringi yobhedu ebotshelelwe phezu kweshaft kunye nendlu, kunye neendawo eziphakathi kweringi kunye nendlu kunye naphakathi kweringi kunye nendlu. Xa injini isebenza, phantsi kwesenzo soxinzelelo lweoyile, kwakheka ifilimu yeoyile ephindwe kabini kwezi ndawo, kwaye i-rotor iyadada kwifilimu yeoyile kwaye ijikeleze ngesantya esiphezulu.

 

Ngenxa yesantya esiphezulu kakhulu sokujikeleza kunye namaqondo obushushu aphezulu kakhulu, le ndawo ikwabeka imfuneko ephezulu kakhulu yokuthambisa nokupholisa.

 

Ukuba i-supercharger ayithambisanga kakuhle kwaye ayipholiswanga, iya kubangela ukuguguleka okungaqhelekanga kwe-bearing, inciphise kakhulu ubomi benkonzo ye-bearing, yonyuse umsantsa phakathi kwe-rotor kunye ne-housing, kwaye inxalenye yeoyile iya kungena kumbhobho wokungenisa okanye umbhobho wokukhupha umoya ukusuka kule nxalenye, nto leyo ekhokelela ekutshisweni kakhulu kokutsha kweoyile.

 

Iintlobo zeiibheringi ezine-turbocharged

Njengenxalenye ephambili ehambayo ye-turbocharger, ulwakhiwo lwe-bearing lunxulumene nokuthembeka kunye nokuqina kwe-turbine. Kukho iintlobo ezimbini eziphambili zee-turbocharger bearings, enye zii-floating bearings kwaye enye zii-ball bearings.

 

Okwangoku, uninzi lwabavelisi beemoto abaphambili basebenzisa iibheringi ezintantayo, ekufuneka zihlale ixesha elide kwaye zifikeleleke ngexabiso eliphantsi. Ibheringi entantayo ngokwenene yindandatho kwi-shaft, kwaye kukho umsantsa phakathi kweringi kunye ne-shaft naphakathi kweringi kunye ne-bearing housing, okwenza ifilimu yeoyile ephindwe kabini. Iringi intanta phakathi kwe-shaft kunye ne-housing. Ngokubanzi, umsantsa womaleko wangaphakathi umalunga ne-0.05mm, kwaye umsantsa womaleko wangaphandle umalunga ne-0.1mm. Ubukhulu bodonga be-bearing bumalunga ne-3.0-4.5mm, kwaye yenziwe nge-tin-lead bronze alloy, kwaye umphezulu we-bearing ugqunywe ngumaleko we-lead-tin alloy okanye i-metal indium enobukhulu obumalunga ne-0.005-0.008mm. Xa i-supercharger isebenza, i-bearing ijikeleza phakathi kwe-shaft kunye ne-housing. Ke ngoko, singafumana iingxaki zeebheringi ezintantayo: ukumelana okuphezulu kokusebenza kwee-turbine shafts, uxinzelelo oluphezulu lweoyile kunye neemfuno zomgangatho, kunye nolawulo oluzinzileyo lwe-turbine shafts.

 

Iibheri zebhola zifumaneka kakhulu kwiimoto ezisebenzayo, kwaye njengoko igama lisitsho, iibheri zebhola yindawo yokufaka iibhola kwi-turbine shaft ukuze zithathe indawo yeoyile kwi-floating bearing. Inzuzo yeebheri zebhola ichasene ngqo neebheri ezidadayo: ukungqubana okuncinci, i-turbine hysteresis ephantsi, kwaye ilungele ngakumbi ukucinezelwa kwemida eguqukayo; Iintshukumo ze-turbine shaft zinokulawulwa ngokufanelekileyo; Uxinzelelo lweoyile kunye nomgangatho zinokuncitshiswa kancinci, nto leyo eyandisa ngokungathanga ngqo ubomi be-turbine. Iintsilelo zayo nazo ziyabonakala, oko kukuthi, ubomi abulunganga njenge-floating bearing, ngokubanzi ukusuka kwiikhilomitha ezingama-70,000 ukuya kuma-80,000 ukuya kumda wobomi, kwaye iindleko zokugcina zibiza kakhulu, ukugcinwa kunzima. Nangona kunjalo, ngenxa yokuthanda iibheri zebhola ngokubhekiselele kumandla, zisesezixhobo eziphambili kwiimoto zokusebenza.
