Gear oils yog ib chav kawm tshwj xeeb ntawm cov roj tshuab tsim los siv rau hauv ntau qhov sib txhuam ntawm cov tsheb sib kis, nrog rau ntau lub thawv iav. Lub cav thiab cov roj kis tau tus mob yog tsim los ntawm cov ntxhia lossis hluavtaws, thiab tom qab ntawd alloyed nrog ntau yam additives, tab sis cov kev xav tau rau cov roj kis tau tus mob siab dua, vim lawv ua haujlwm ntawm ntau dua loads thiab zawv zawg ceev ntawm qhov chaw txhuam.
Ib qho tseem ceeb tshaj plaws ntawm cov roj no yog lub peev xwm los tsim cov yeeb yaj kiab tiv thaiv ntawm qhov chaw ntawm kev sib txhuam kom tiv thaiv kev sib cuag ntawm lawv. Nyob rau hauv lub zog hypoid, cov roj yog siv, uas, nkag mus rau hauv cov tshuaj tiv thaiv nrog rau qhov chaw ntawm qhov chaw, tiv thaiv lawv boiling, thiab muaj zog heev zog. Thaum lub sijhawm ua haujlwm, cov roj iav oxidize thiab ua paug, yog li lawv yuav tsum tau hloov tsis tu ncua. Cov roj uas tsis tshua muaj siab oxidize yog suav tias yog qhov zoo. Txij li cov tuam ntxhab sib txawv siv cov khoom sib txawv, koj tsis tuaj yeem sib tov lawv cov khoom. Thaum hloov cov khoom sib txuas, nws yuav tsum tau ntxuav kom huv si, yog tias ua tau nrog tib cov roj tshiab.
Classifyiav roj los ntawm viscosity los yog kev ua tau zoo. Yog li raws li SAE (Association of Automotive Engineers), lawv tau muab faib ua cuaj chav kawm - tsib lub caij ntuj sov thiab plaub lub caij ntuj no (nrog rau W Performance index). Rau txhua chav kawm, qhov ntsuas viscosity yog qhia. Piv txwv li, SAE 70W los yog SAE 250. Rau cov roj ntau ntau, qhia qhov ntsuas ob npaug (SAE 80W-90, thiab lwm yam).
API (American Petroleum Institute) faib cov roj rau hauv 6 chav kawm nyob ntawm qhov ua tau zoo - GL-1…GL-6. Cov chav kawm no zoo ib yam li cov siv hauv Soviet GOST 17479.2-85 TM1 … TM6. Cov pab pawg thib tsib thiab thib rau yog siv rau lub zog hypoid thiab muaj lubricity siab tshaj plaws thiab kev ua haujlwm siab heev.
Thaum xaiv cov roj iav, koj yuav tsum tsom ntsoov rau lawv qhov kev ua haujlwm. Yog tias qib qis dua qhov tsim nyog, cov txheej txheem yuav tsuas ua tsis tiav, thiab qib siab ntawm cov roj muaj tus nqi siab dua, uas yuav ua rau tus nqi overruns. Nws tseem yog ib qho tseem ceeb uas yuav tau xav txog qhov kub ntawm qhov kev sib kis yuav ua haujlwm, thiab raws li qhov no, xaiv cov roj nplua nyeem. SAE 85W, piv txwv li, yuav ua haujlwm ntawm qhov kub thiab txias mus rau -12 ° C, thiab 85W twb poob mus rau -40 ° C. Kev sib kis tsis siv neeg siv cov kua dej tshwj xeeb uas tsis muaj viscosity, yog li tsis muaj lub cav lossis cov roj kis tau siv.
Hnub no, ntau lub tuam txhab muab lawv cov roj iav ntawm kev ua lag luam - Lukoil, Total, Texaco, Reksol, Norsi thiab ntau lwm tus. Ntau yam ntawm cov tshuaj ntxiv uas siv los txiav txim siab li cas qibroj zoo, thiab lawv cov nqi ntau. Mineral, raws li txoj cai, tus nqi tsawg dua, tab sis ua haujlwm tsawg dua, cov khoom sib xyaw yog qhov sib txawv. Ib qho kev sib haum xeeb zoo hauv qhov no yuav yog semi-synthetics, raws li lub ntsiab lus kub ntawm thawj ob. Koj yuav tsum tau ceev faj txog cov khoom cuav thiab tsis txhob yuav cov roj hauv cov khw muag khoom tsis tau lees paub. Hloov lub gearbox yeej ib txwm kim dua li kev noj cov roj zoo, zoo, tshwj xeeb tshaj yog txij li tam sim no lawv siv 60,000 lossis ntau dua mais ntawm kev hloov mus hloov.

Txhua tus tswv tsheb paub tias nws tseem ceeb npaum li cas los xaiv cov roj cav kom raug. Tsis tsuas yog kev ua haujlwm ruaj khov ntawm cov hlau "lub siab" ntawm lub tsheb nyob ntawm qhov no, tab sis kuj yog cov peev txheej ntawm nws txoj haujlwm. Cov roj zoo tiv thaiv cov txheej txheem los ntawm ntau yam tsis zoo. Ib qho ntawm cov khoom siv nrov tshaj plaws hauv peb lub teb chaws yog roj nrog viscosity Performance index ntawm 5W30. Nws tuaj yeem hu ua universal. Qhov ntsuas roj 5W30 yuav tau tham hauv kab lus
