Chii chinonzi turbo bearing? Mhando dzemabheringi ane turbocharged

Turbo bearingndiyo bearing iri mu turbocharger, kuti tinzwisise turbocharger, tinofanira kutanga taziva turbocharger nezvikamu zvayo zvinofamba.

 

Chii chinonzi turbocharger?

Turbocharger, yatinowanzoona mumotokari, chaizvoizvo imhepo inodzvanya mhepo kuti iwedzere huwandu hwemhepo inotorwa. Inoshandisa inertial impulse yegasi rinobuda muinjini kusunda turbine mukamuri returbine, uye turbine inotyaira coaxial impeller, uye impeller inodzvanya mweya unotumirwa nepaipi ye air filter kuti uidzvanye mu cylinder. Kana kumhanya kweinjini kukawedzera, kumhanya kwekubuda kwegasi rinobuda mu exhaust uye kumhanya kwe turbine zvinowedzerawo zvakafanana, impeller inodzvanya mhepo yakawanda mu cylinder, kumanikidzwa uye kuwanda kwemhepo kunogona kupisa mafuta akawanda, kuwedzera huwandu hwemafuta uye kugadzirisa kumhanya kweinjini, unogona kuwedzera simba reinjini.

 

Ndezvipi zvikamu zvinofamba zve turbocharger?

Zvikamu zvinofamba zve turbocharger ndizvowo zvinhu zvikuru - vhiri re turbine, compressor impeller uye rotor shaft, uye imba ye supercharger ine kufamba kwekumhanya kwakanyanya, izvo zvisingatsungiririki nemabearing akajairwa, saka bearing ye supercharger ibheyaringi yakakosha inoyangarara.

 

Chaizvoizvo irin'i remhangura rakasungirirwa pamusoro pemubato neimba, rine nzvimbo dzakati siyanei pakati perin'i neimba uye pakati perin'i neimba. Kana injini ichishanda, pasi pesimba remafuta, firimu remafuta maviri rinoumbwa muzvikamu izvi, uye rotor inoyangarara pafirimu remafuta uye inotenderera nekumhanya kukuru.

 

Nekuda kwekumhanya kwakanyanya uye tembiricha yakakwira zvakanyanya, nzvimbo iyi inodawo mafuta ekuzora nekutonhodza zvakanyanya.

 

Kana supercharger isina kuzorwa zvakanaka uye kutonhodzwa, inokonzera kusakara kusingawanzoitiki kwebearing, inopfupisa hupenyu hwebearing, inowedzera mukaha uri pakati perotor neimba, uye chikamu chemafuta chichapinda mupipe yekupinda kana exhaust kubva muchikamu ichi, zvichikonzera kutadza kushanda kwemafuta zvakanyanya.

 

Mhando dzemabheyaringi ane turbocharged

Sechikamu chikuru che turbocharger chinofamba, chimiro che bearing chine chekuita nekuvimbika uye kugara kwenguva refu kwe turbine. Kune mhando mbiri huru dze turbocharger bearings, imwe i floating bearings uye imwe i ball bearings.

 

Parizvino, vazhinji vevagadziri vemotokari vakuru vanoshandisa mabheyaringi anoyangarara, ayo anofanira kugara kwenguva refu uye anodhura zvishoma. Mabheyaringi anoyangarara chaizvoizvo idenderedzwa riri pashaft, uye pane mukaha uri pakati perin'i neshaft uye pakati perin'i nebearing housing, zvichiita firimu remafuta maviri. Rin'i inoyangarara pakati peshaft nebearing. Kazhinji, mukaha wemukati unenge 0.05mm, uye mukaha wekunze unenge 0.1mm. Ukobvu hwemadziro ebhearing hunenge 3.0-4.5mm, uye hwakagadzirwa netin-lead bronze alloy, uye pamusoro pebearing pakafukidzwa ne lead-tin alloy kana metal indium ine ukobvu hunenge 0.005-0.008mm. Kana supercharger ichishanda, bearing inotenderera pakati peshaft nebearing. Nokudaro, tinogona kuwana zvakaipira mabheyaringi anoyangarara: kuramba kumhanya kwakanyanya kwemashaft eturbine, kumanikidzwa kwakanyanya kwemafuta uye zvinodiwa zvemhando yepamusoro, uye kudzora dynamic dynamic kwemashaft eturbine.

 

Mabheya ebhora anowanikwa zvakanyanya mumota dzinoshanda, uye sezita racho, mabheya ebhora inzvimbo yekuisa mabhora pa turbine shaft kuti atsive mafuta ari mufloating bearing. Kubatsira kwemabheya ebhora kwakasiyana chaizvo nemabheya anoyerera: kukweshana kushoma, turbine hysteresis yakaderera, uye zvakanakira kudzvanywa kwemiganhu inochinja; kushanduka kwe turbine shaft kunogona kudzorwa zvinobudirira; Kumanikidzwa kwemafuta uye mhando zvinogona kuderedzwa zvishoma, izvo zvinowedzera hupenyu hwe turbine zvisina kunanga. Kushaikwa kwayo kuri pachenawo, kureva kuti, hupenyu hahuna kunaka sefloating bearing, kazhinji makiromita 70,000 kusvika 80,000 kusvika pamuganhu wehupenyu, uye mutengo wekugadzirisa unodhura, kugadzirisa kwakaoma. Zvisinei, nekuda kwekukwezva kwemabheya ebhora maererano nesimba, achiri michina mikuru pamota dzinoshanda.
