Iyini i-turbo bearing? Izinhlobo zama-turbocharged bearing

Ukuthwala kwe-Turboyi-bearing ku-turbocharger, ukuze siqonde i-turbocharger, okokuqala sidinga ukwazi i-turbocharger nezingxenye zayo ezihambayo.

 

Iyiphi i-turbocharger?

I-turbocharger, esivame ukuyithola ezimotweni, empeleni iyi-air compressor ecindezela umoya ukuze ikhulise inani lomoya othathwayo. Isebenzisa i-inertial impulse yegesi yokukhipha ekhishwa yinjini ukuze icindezele i-turbine ekamelweni le-turbine, futhi i-turbine ishayela i-coaxial impeller, futhi i-impeller icindezela umoya othunyelwa yipayipi lokuhlunga umoya ukuze uwucindezele ungene kwisilinda. Lapho ijubane lenjini landa, ijubane lokukhipha igesi yokukhipha kanye nejubane le-turbine nakho kuyanda ngesikhathi esifanayo, i-impeller icindezela umoya omningi ungene kwisilinda, ingcindezi kanye nobuningi bomoya ukwanda kungashisa uphethiloli omningi, kwandise inani likaphethiloli futhi kulungise ijubane lenjini, ungandisa amandla okukhipha enjini.

 

Yiziphi izingxenye ezihambayo ze-turbocharger?

Izingxenye ezihambayo ze-turbocharger nazo ziyizingxenye eziyinhloko - isondo le-turbine, i-compressor impeller kanye ne-rotor shaft, kanye ne-supercharger housing inokunyakaza okulinganiselwe okusheshayo, okungabekezeleleki kuma-bearings avamile, ngakho-ke i-bearing ye-supercharger iyi-bearing ekhethekile entantayo.

 

Empeleni iyindandatho yethusi eboshwe ngemikhono phezu kweshafti nendawo yokuhlala, enezikhala phakathi kwendandatho nendawo yokubamba kanye naphakathi kwendawo yokubamba. Lapho injini isebenza, ngaphansi kwesenzo sokucindezela uwoyela, kwakheka ifilimu kawoyela ephindwe kabili kulezi zingxenye, futhi i-rotor empeleni iyantanta efilimu kawoyela futhi ijikeleze ngesivinini esikhulu.

 

Ngenxa yesivinini esikhulu kakhulu sokujikeleza kanye namazinga okushisa aphezulu kakhulu, le ndawo ibeka nezidingo eziphezulu kakhulu zokugcotshwa nokupholisa.

 

Uma i-supercharger ingagcotshwanga kahle futhi ingapholiswanga kahle, izobangela ukuguguleka okungavamile kwe-bearing, ifinyeze kakhulu impilo yesevisi ye-bearing, yandise igebe phakathi kwe-rotor kanye ne-housing, futhi ingxenye yamafutha izongena epayipini lokungenisa noma epayipini lokukhipha umoya elivela kule ngxenye, okuholela ekungasebenzi kahle okukhulu kokusha kwamafutha.

 

Izinhlobo zeamabheringi ane-turbocharged

Njengengxenye ebalulekile ehambayo ye-turbocharger, isakhiwo se-bearing sihlobene nokuthembeka nokuqina kwe-turbine. Kunezinhlobo ezimbili eziyinhloko zama-turbocharger bearing, enye ingama-floating bearing kanti enye ingama-ball bearing.

 

Njengamanje, iningi labakhiqizi bezimoto abakhulu basebenzisa ama-floating bearings, okufanele ahlale isikhathi eside futhi angabizi. I-floating bearings empeleni iyindandatho emgodleni, futhi kukhona igebe phakathi kwendandatho nomgodla naphakathi kwendandatho nomgodla wokuthwala, okwenza ifilimu kawoyela ephindwe kabili. Indandatho iyantanta phakathi komgodla nomgodi. Ngokuvamile, igebe lesendlalelo sangaphakathi lingaba ngu-0.05mm, kanti igebe lesendlalelo sangaphandle lingaba ngu-0.1mm. Ubukhulu bodonga lwe-bearings bungaba ngu-3.0-4.5mm, futhi lwenziwe nge-tin-lead bronze alloy, kanti ubuso be-bearings bumbozwe ungqimba lwe-lead-tin alloy noma i-metal indium enobukhulu obungaba ngu-0.005-0.008mm. Lapho i-supercharger isebenza, i-bearings ijikeleza phakathi komgodla nomgodi. Ngakho-ke, singathola ukungalungi kwama-floating bearings: ukumelana okuphezulu kokusebenza kwama-turbine shafts, umfutho ophezulu kawoyela nezidingo zekhwalithi, kanye nokulawulwa okuguquguqukayo okungazinzile kwama-turbine shafts.

 

Ama-ball bearings avame ukutholakala ezimotweni zokusebenza, futhi njengoba igama lisikisela, ama-ball bearings ayindawo yokufaka amabhola ku-turbine shaft ukuze kuthathelwe indawo uwoyela ku-floating bearings. Inzuzo yama-ball bearings iphambene ngqo nama-floating bearings: ukungqubuzana okuncane, i-turbine hysteresis ephansi, futhi ilungele kakhulu ukucindezela imikhawulo eguquguqukayo; Amandla e-turbine shaft angalawulwa ngempumelelo; Ukucindezela kukawoyela kanye nekhwalithi kungancishiswa kancane, okwandisa ngokungaqondile impilo ye-turbine. Ukushiyeka kwayo nakho kusobala, okungukuthi, impilo ayinhle njenge-floating bearings, ngokuvamile ukusuka kumakhilomitha angu-70,000 kuya ku-80,000 kuya emkhawulweni wokuphila, futhi izindleko zokulungisa ziyabiza, ukulungiswa kunzima. Kodwa-ke, ngenxa yokukhanga kwama-ball bearings maqondana namandla, aseyimishini eyinhloko ezimotweni zokusebenza.
