Amafutha eGear 80W90. Ukubekezelela kanye nemingcele yokusebenza
I-Deciphering gear oil 80W90
Ake sicabangele kafushane izici eziyinhloko amafutha egiya ane-viscosity ye-80W90. Izinga le-SAE J300 lisho lokhu okulandelayo.
- Indawo yokuthela ngaphambi kokulahlekelwa kwezakhiwo zokugcoba nezivikelayo isezingeni lika -26 ° C. Uma iqhwa ngaphansi kwaleli zinga lokushisa, i-viscosity eguquguqukayo yamafutha izodlula umkhawulo owamukelekayo ongu-150000 csp owamukelwe onjiniyela be-SAE. Lokhu akusho ukuthi amafutha azophenduka iqhwa. Kodwa ngokungaguquguquki, iyoba njengoju olujiyile. Futhi i-lubricant enjalo ngeke nje ikwazi ukuvikela amapheya alayishiwe, kodwa ngokwayo iyoba isithiyo ekusebenzeni okujwayelekile kweyunithi.
- I-kinematic viscosity ku-100 ° C yalesi sigaba samafutha akumele iwele ngaphansi kuka-24 cSt.. Kuzwakala kuxakile maqondana namayunithi okudlulisa: izinga lokushisa ngu-100 ° C. Uma i-gearbox noma i-axle ifudumala kuze kufike kulokhu kushisa, khona-ke kungenzeka ukuthi kunezinkinga ezithile emhlanganweni wokudlulisa, noma umthwalo ovunyelwe udlulile. Kodwa-ke, i-viscosity engu-100 ° C iyacatshangelwa lapha, ngoba ifilimu kawoyela ingaphansi kwengcindezi enkulu kuma-patches okuxhumana futhi ingashiswa endaweni ibe yizinga lokushisa eliphakeme. Futhi uma i-viscosity inganele, khona-ke ifilimu izodiliza kalula futhi ivumele insimbi ukuthi ixhumane nensimbi ngokuqondile, okuzobangela ukugqoka okusheshayo kwezingxenye zomhlangano. Ngokungaqondile, ingxenye yenkomba "yehlobo" inquma izinga lokushisa eliphezulu elivumelekile lasehlobo, okuthi kuwoyela okukhulunywa ngawo kube +35 °C.
Ngokuvamile, i-viscosity iyinkomba eyinhloko. Nguye onquma ukuziphatha kwamafutha egiya elithile kumazinga okushisa ahlukene.
Ububanzi kanye analogue zasekhaya
Ububanzi bawoyela wegiya we-80W90 bukhawulelwe hhayi ngemikhawulo yokushisa kuphela, kodwa nangezinye izakhiwo, njengokuthi: ikhono lokwenza ifilimu eqinile, ukumelana namagwebu kanye ne-oxidation, impilo yesevisi, ukuhlukunyezwa kwezingxenye zenjoloba nepulasitiki. Lezi nezinye izakhiwo zikawoyela wegiya zichazwe kabanzi ngezinga le-API.
Namuhla eRussia, amafutha egiya angu-80W90 anezigaba ze-API i-GL-4 ne-GL-5 avame kakhulu kunabanye. Kwesinye isikhathi ungathola nezinto zokuthambisa zekilasi le-GL-3. Kodwa namuhla acishe aqedwa ngokuphelele.
Amafutha 80W90 GL-4. Isetshenziswa kuma-gearbox amaningi avumelanisiwe namanye amayunithi okudlulisela ezimoto zasekhaya nezangaphandle. Iyakwazi ukushintshaniswa namafutha ekilasi le-GL-3, kodwa iqukethe iphakheji ethuthuke kakhulu yezithasiselo, ikakhulukazi izithasiselo zokucindezela okukhulu. Inezinto ezinhle zokugcoba nezivikelayo. Iyakwazi ukusebenza ngamagiya e-hypoid, lapho umthwalo wokuxhumana ungadluli ku-3000 MPa.
I-Gear oil 80W90 class GL-5 ngokusho kwe-API ithathe indawo ye-GL-4, isivele isiphelelwe yisikhathi ezimotweni ezintsha. Ivikela ngokuthembekile amapheya e-hypoid friction ngokususwa okukhulu kwezimbazo, lapho imithwalo yokuxhumana idlula i-3000 MPa.
Nokho, la mafutha angeke asetshenziswe njalo kuma-gearbox aklanyelwe izinga le-GL-4. Konke kumayelana ne-coefficient ephansi kakhulu yokungqubuzana, etholwa ngephakheji ye-additive ethuthukisiwe. Ama-synchronizers of simple manual transmissions asebenza ngenxa ye-coefficient of friction. Okusho ukuthi, i-synchronizer icindezelwa ngokumelene negiya futhi ilinganisa isivinini sokujikeleza kwama-shafts ngokushesha ngaphambi kokuba amagiya angene egiyeni. Ngenxa yalokhu, ukudluliswa kuzovula kalula.
Uma usebenzisa uwoyela we-GL-5, amabhokisi kagiya avunyelanisiwe angadalelwe leli zinga avame ukuba nokushintshwa kwegiya eliqinile kanye nokushwabana kwesici ngenxa yokushelela kwe-synchronizer. Yize umnikazi wemoto ebona ukwanda kwamandla emoto kanye nokwehla kokusetshenziswa kukaphethiloli ngenxa ye-coefficient ephansi yokungqubuzana. Futhi, ama-synchronizers ahluleka ngesivinini esisheshayo emabhokisini angaklanyelwe ukusebenza namafutha e-GL-5.
Amanye amayunithi okudlulisa adinga ukugcotshwa okulula kwezindlela zokudlulisa amandla angase agcwaliswe ngowoyela we-GL-5 esikhundleni se-GL-4.
Intengo yamafutha angu-80W90 iqala kuma-ruble angu-140 ilitha ngalinye. Yile malini izindleko zokugcoba ezilula zasekhaya, isibonelo, uhlobo lwe-OilRight. Ithegi yentengo ejwayelekile iyashintshashintsha cishe kuma-ruble angama-1-300. Izindleko zemikhiqizo ephezulu zifinyelela kuma-ruble ayi-400 ilitha ngalinye.
Inguqulo yasekhaya yamafutha angu-80W90 ngokusho kwesigaba esidala ibizwa ngokuthi i-TAD-17, ngokusho kwentsha - TM-4-18 (efana ne-80W90 GL-4) noma i-TM-5-18 (efana ne-80W90 GL-5) .
