Kugawika kwa mafuta a gear kumathandizira kusankha kapangidwe koyenera

Gulu lapadziko lonse lapansi lamafuta otumizira limalola eni magalimoto kusankha mosavuta mawonekedwe oyenera a ma gearbox, milandu yotengera, ma unyolo ndi ma drive a gear, njira zowongolera za kavalo wawo wachitsulo.

Gulu la API lamafuta amafuta

Ndi dongosolo lamagulu lomwe limagawaniza mitundu yonse yamagulu m'magulu asanu. Mnzake waku Europe ndi ZF TE-ML, yemwe amafotokoza mwamtheradi zolemba zonse zama hydromechanical transmission. Magulu otsatirawa a API amasiyanitsidwa kutengera mfundo zogwirira ntchito ndi kapangidwe ka kufalitsa, kuchuluka kwa zowonjezera zapadera:

• GL-1: zamadzimadzi popanda zowonjezera, ndizotheka kuwonjezera odana ndi thovu zosavuta, antioxidant, depressant, odana ndi dzimbiri zina ku mitundu ina ya mafuta giya pang'ono. Oyenera magalimoto ndi makina ntchito ulimi.
• GL-2: nthawi zambiri amatsanuliridwa pakufalitsa magawo aulimi, amakhala ndi zowonjezera zotsutsana ndi kuvala.
• GL-3: si yoyenera magiya a hypoid, kuchuluka kwa zowonjezera zomwe zimachepetsa kuvala pazigawo zamagalimoto ndi pafupifupi 2,7 peresenti.
• GL-4: nyimbo zomwe zimagwiritsidwa ntchito pamagiya olumikizana omwe amagwira ntchito pansi pa mphamvu yokoka zosiyanasiyana, m'magiya akuluakulu amtundu uliwonse wamayendedwe ndi ma gearbox osalumikizana. Madzi a GL-4, malinga ndi gulu la API lamafuta amagetsi, ali ndi zowonjezera zinayi za EP.
• GL-5: osati ntchito gearboxes, koma, monga chilengedwe, oyenera kufala zina zilizonse, lili ndi kuchuluka kwa multifunctional zina (mpaka 6,5%).

Gear mafuta classification System

SAE Gear Oil Viscosity

Gulu lodziwika bwino la ku America lamafuta amagetsi ndi mamasukidwe akayendedwe amitundu yosiyanasiyana wamba. Makampani ogulitsa magalimoto amaganiziranso za SAE. Ndipo pamaziko awo amapereka malingaliro pa kusankha nyimbo zotumizira ma gearbox amakina ndi ma axles (otsogolera). The gear mafuta mamasukidwe akayendedwe index (Mwachitsanzo, 85W0140) amasonyeza magawo waukulu wa madzimadzi ndi kuwagawa m'chilimwe ndi yozizira (chilembo "W"). Kuyika chizindikiro ichi kwamafuta a giya ndikosavuta komanso kumamveka kwa oyendetsa.

Ndikofunika kudziwa momwe mafuta a gear amasankhidwira: kugawanika ndi kusankha kwa nyimbo kumachitika motsatira zizindikiro ziwiri za viscosity - kutentha kwakukulu ndi kutsika. Chizindikiro choyamba chimachokera pamaziko a kinematic viscosity pa malo otentha amadzimadzi, chachiwiri - poyesa kutentha komwe mapangidwe ake ali ndi chizindikiro cha 150000 cP (Brookfield viscosity). Pali tebulo lapadera la viscosity la mafuta a gear, omwe opanga awo amatsogoleredwa.

Kusankhidwa kwa mafuta otumizira ndi mtundu wagalimoto

M'malo mwake, kusankha koteroko sikovuta kupanga nokha, ngati muphunzira mfundo zamagulu ndi kusankha mafuta a gear. Choyamba muyenera kuyang'ana chivomerezo cha wopanga magalimoto pagawo lomwe limagwiritsidwa ntchito pagalimoto yanu, komanso kukhuthala kwamafuta a gear molingana ndi SAE. Kenako gwirani ndi gulu lamtundu wamadzimadzi molingana ndi gulu la European (ACEA) ndi American (API) lamafuta amafuta:

• kwa injini za petulo - ACEA (A1-A5): khalidweli limatengedwa kuti ndilopamwamba, chiwerengero chachikulu pambuyo pa chilembo A;
• kwa injini za dizilo - ACEA (B1-B5);
• chilengedwe cha mayunitsi dizilo anaika pa magalimoto pambuyo 2004 - ACEA (С1-С5);
• kwa magalimoto dizilo katundu - API gulu "C";
• kwa injini zamafuta - API gulu "S".

Ndipo musaiwale kuti alumali moyo wa giya mafuta nthawi zambiri okha zaka zisanu kuchokera tsiku kupanga.
