Mafuta a Gear 80W90. Tolerances ndi ntchito magawo
Kuzindikira zida zamafuta 80W90
Tiyeni tione mwachidule makhalidwe akuluakulu omwe ali ndi mafuta a giya okhala ndi kukhuthala kwa 80W90. Muyezo wa SAE J300 umanena izi.
- Kuthira kusanachitike kutayika kwa mafuta ndi zoteteza katundu ali pa -26 ° C. Kuzizira pansi pa kutenthaku, kukhuthala kwamafuta kumadutsa malire ovomerezeka a 150000 csp omwe amavomerezedwa ndi akatswiri a SAE. Izi sizikutanthauza kuti mafutawo adzasanduka ayezi. Koma mosasinthasintha, adzakhala ngati uchi wokhuthala. Ndipo mafuta oterowo sangathe kuteteza mawiri awiri osakanikirana, koma palokha idzakhala cholepheretsa kugwira ntchito kwa unit.
- Kukhuthala kwa kinematic pa 100 ° C kwa kalasi iyi yamafuta sikuyenera kugwa pansi pa 24 cSt.. Zimamveka zachilendo pokhudzana ndi magawo opatsirana: kutentha ndi 100 ° C. Ngati gearbox kapena chitsulo chothandizira kutentha mpaka kutentha kotereku, ndiye kuti pali zovuta zina mu msonkhano wotumizira, kapena katundu wololedwa wadutsa. Komabe, kukhuthala kwa 100 ° C kumaganiziridwa pano, chifukwa filimu yamafuta ili pansi pa kupsinjika kwakukulu pazigawo zolumikizana ndipo imatha kutenthedwa kwanuko mpaka kutentha kwambiri. Ndipo ngati mamasukidwe akayendedwe sakwanira, ndiye kuti filimuyo idzaphwanyidwa mosavuta ndikulola zitsulo kuti zigwirizane ndi zitsulo mwachindunji, zomwe zidzachititsa kuti zigawo za msonkhano ziwonongeke. Mosalunjika, gawo la "chilimwe" la index limasankha kutentha kovomerezeka kwa chilimwe, komwe kwamafuta omwe akufunsidwa ndi +35 ° C.
Nthawi zambiri, mamasukidwe akayendedwe ndiye chizindikiro chachikulu. Ndi iye amene amatsimikiza khalidwe la mafuta giya inayake mu osiyanasiyana kutentha.
Kukula ndi ma analogue apanyumba
Kukula kwa 80W90 gear mafuta kumachepetsedwa osati ndi malire a kutentha, komanso ndi zinthu zina, monga: luso lopanga filimu yolimba, kukana kutulutsa thovu ndi makutidwe ndi okosijeni, moyo wautumiki, nkhanza za mphira ndi pulasitiki. Izi ndi zina zamafuta amafuta akufotokozedwa mwatsatanetsatane ndi muyezo wa API.
Masiku ano ku Russia, mafuta a giya 80W90 okhala ndi makalasi a API GL-4 ndi GL-5 ndiofala kuposa ena. Nthawi zina mumatha kupezanso mafuta amtundu wa GL-3. Koma lero iwo atsala pang'ono kuthetsedwa.
Mafuta 80W90 GL-4. Amagwiritsidwa ntchito m'mabokosi osakanikirana ambiri ndi magawo ena otumizira magalimoto apanyumba ndi akunja. Mafuta amtundu wa GL-3 amatha kusinthana, koma amakhala ndi zowonjezera zowonjezera, makamaka zowonjezera zowonjezera. Ili ndi mafuta abwino komanso chitetezo. Kutha kugwira ntchito ndi magiya a hypoid, momwe kulumikizidwa sikudutsa 3000 MPa.
Gear mafuta 80W90 kalasi GL-5 malinga API walowa m'malo kalasi GL-4, kale chikale kwa magalimoto atsopano. Imateteza modalirika awiriawiri amtundu wa hypoid ndi kusamuka kwakukulu kwa nkhwangwa, momwe katundu wolumikizana amapitilira 3000 MPa.
Komabe, mafuta awa sangagwiritsidwe ntchito nthawi zonse m'mabokosi opangira GL-4. Zonse ndi za coefficient yotsika kwambiri ya kukangana, yomwe imatheka kudzera mu phukusi lapamwamba lowonjezera. Ma synchronizers osavuta otumizirana pamanja amagwira ntchito chifukwa cha kuchuluka kwa mikangano. Ndiko kuti, synchronizer imapanikizidwa motsutsana ndi zida ndikufanana ndi liwiro la kuzungulira kwa ma shafts nthawi yomweyo magiya asanalowe mu gear. Chifukwa cha ichi, kufala kudzayatsa mosavuta.
Mukamagwiritsa ntchito mafuta a GL-5, ma gearbox olumikizidwa omwe sanapangidwe mwanjira imeneyi nthawi zambiri amakumana ndi kusintha kwa zida zolimba komanso kutsika kwamakhalidwe chifukwa cha kutsetsereka kwa synchronizer. Ngakhale mwini galimotoyo amatha kuwona kuwonjezeka kwa mphamvu zamagalimoto komanso kuchepa kwamafuta chifukwa cha kutsika kocheperako. Komanso, ma synchronizers amalephera pa liwiro lothamanga pamabokosi omwe sanapangidwe kuti azigwira ntchito ndi mafuta a GL-5.
Magawo ena opatsirana omwe amafunikira mafuta osavuta a njira zotumizira mphamvu amatha kudzazidwa ndi mafuta a GL-5 m'malo mwa GL-4.
Mtengo wamafuta 80W90 umayamba pa ma ruble 140 pa lita imodzi. Umu ndi momwe mafuta osavuta am'nyumba amawonongera, mwachitsanzo, mtundu wa OilRight. Mtengo wapakati umasinthasintha pafupifupi ma ruble 1-300. Mtengo wazinthu zapamwamba umafika ma ruble 400 pa lita imodzi.
The zoweta Baibulo 80W90 mafuta malinga ndi gulu wakale amatchedwa TAD-17, malinga ndi latsopano - TM-4-18 (ofanana 80W90 GL-4) kapena TM-5-18 (wofanana 80W90 GL-5) .
