ʻO ka ʻaila huila 80W90. ʻO ka hoʻomanawanui a me nā ʻāpana hana
Deciphering gear aila 80W90
E noʻonoʻo pōkole mākou i nā hiʻohiʻona nui i loaʻa i nā aila me ka viscosity o 80W90. 'Ōlelo ka SAE J300 maʻamau i kēia.
- ʻO ka wahi ninini ma mua o ka nalowale ʻana o ka lubricating a me nā waiwai pale ma -26 ° C. Ke hoʻoheheʻe ʻia ma lalo o kēia mahana, ʻoi aku ka viscosity ikaika o ka aila ma mua o ka palena ʻae ʻia o 150000 csp i ʻae ʻia e nā ʻenekini SAE. ʻAʻole kēia manaʻo e lilo ka momona i hau. Akā, i ka paʻa ʻana, e lilo ia e like me ka meli mānoanoa. A ʻaʻole hiki i kēlā lubricant ke pale wale i nā pālua friction i hoʻouka ʻia, akā iā ia iho e lilo i mea keakea i ka hana maʻamau o ka ʻāpana.
- ʻAʻole pono e hāʻule ka viscosity kinematic ma 100 °C no kēia papa ʻaila ma lalo o 24 cSt.. He mea ʻē ia e pili ana i nā ʻāpana hoʻouna: ʻo 100 ° C ka mahana. Inā hoʻomehana ka pahu pahu a i ʻole axle i kēlā mehana, a laila aia kekahi mau pilikia i ka hui hoʻouna, a i ʻole ua ʻoi aku ka ukana i ʻae ʻia. Eia nō naʻe, ʻike ʻia ka viscosity ma 100 °C ma ʻaneʻi, no ka mea, ʻoi aku ke koʻikoʻi o ke kiʻi ʻaila i loko o nā ʻāpana pili a hiki ke hoʻomehana ʻia i nā wahi kiʻekiʻe. A inā ʻaʻole lawa ka viscosity, a laila e ʻoi aku ka maʻalahi o ke kiʻiʻoniʻoni a ʻae i ka metala e hoʻopili pololei i ka metala, kahi e wikiwiki ai ka ʻaʻahu o nā ʻāpana hui. ʻAʻole pololei, ʻo ka ʻāpana "kauwela" o ka papa kuhikuhi e hoʻoholo i ka wela wela o ke kauwela i ʻae ʻia, no ka ʻaila i nīnau ʻia he +35 °C.
Ma keʻano laulā, ʻo ka viscosity ka hōʻailona nui. ʻO ia ka mea nāna e hoʻoholo i ke ʻano o ka ʻaila ʻaila ma nā pae wela like ʻole.

ʻAʻole i kaupalena ʻia ke ʻano o ka ʻaila gear 80W90 wale nō e nā palena wela, akā e nā waiwai ʻē aʻe, e like me: ka hiki ke hana i kahi kiʻiʻoniʻoni ikaika, kūʻē i ka ʻāʻī a me ka oxidation, ke ola lawelawe, ka huhū i nā ʻāpana a me nā ʻāpana plastic. ʻO kēia mau mea a me nā waiwai ʻē aʻe o ka ʻaila kaila i wehewehe ʻia e ka maʻamau API.
I kēia lā ma Rūsia, ʻoi aku ka maʻamau o nā ʻaila 80W90 me nā papa API GL-4 a me GL-5 ma mua o nā mea ʻē aʻe. I kekahi manawa hiki iā ʻoe ke loaʻa i nā lubricants papa GL-3. Akā i kēia lā ua aneane pau loa lākou.
Aila 80W90 GL-4. Hoʻohana ʻia ia i ka hapa nui o nā gearboxes a me nā ʻāpana hoʻoili ʻē aʻe o nā kaʻa kūloko a me nā haole. Hiki ke hoʻololi ʻia me nā aila papa GL-3, akā loaʻa i kahi pūʻolo o nā mea hoʻohui, ʻoi aku ka nui o nā mea hoʻohui. Loaʻa iā ia ka lubricating maikaʻi a me nā mea pale. Hiki ke hana me nā mea hana hypoid, kahi i ʻoi aku ai ka hoʻopili pili ʻana ma mua o 3000 MPa.
ʻO ka aila Gear 80W90 papa GL-5 e like me ka API ua hoʻololi i ka papa GL-4, i hala ʻole no nā kaʻa hou. Hoʻopaʻa paʻa ʻia i nā pālua friction hypoid me kahi neʻe nui o nā koʻi, kahi i ʻoi aku ka nui o nā ukana pili i 3000 MPa.
Eia naʻe, ʻaʻole hiki ke hoʻohana mau ʻia kēia ʻaila i nā pahu pahu i hoʻolālā ʻia no ka maʻamau GL-4. E pili ana i ke koena haʻahaʻa loa o ka friction, i loaʻa ma o kahi pūʻolo hoʻohui kiʻekiʻe. Hoʻohana nā mea hoʻonohonoho o nā hoʻoili lima maʻalahi ma muli o ka coefficient o friction. ʻO ia hoʻi, paʻi ka synchronizer i ka mīkini a hoʻohālikelike i ka wikiwiki o ka hoʻololi ʻana o nā shafts ma mua o ke komo ʻana o nā mea hana i loko o ka pahu. Mahalo i kēia, e maʻalahi ka hoʻouna ʻana.
Ke holo nei ma ka aila GL-5, ʻike pinepine ʻia nā pahu pahu i hoʻonohonoho ʻia ʻaʻole i hoʻolālā ʻia no kēia maʻamau i nā loli paʻa paʻa a me kahi crunch hiʻohiʻona ma muli o ka paheʻe synchronizer. ʻOiai hiki i ka mea nona ke kaʻa ke ʻike i ka piʻi ʻana o ka mana o ke kaʻa a me ka emi ʻana o ka hoʻohana wahie ma muli o ka haʻahaʻa haʻahaʻa haʻahaʻa o ka friction. Eia kekahi, ʻaʻole hiki i nā synchronizers ke holo wikiwiki i nā pahu i hana ʻole ʻia e hana me ka ʻaila GL-5.
Hiki ke hoʻopiha ʻia nā ʻāpana hoʻouna ʻē aʻe e koi ana i ka lubrication maʻalahi o nā mīkini hoʻouna ikaika me ka ʻaila GL-5 ma kahi o GL-4.
Hoʻomaka ke kumukūʻai o nā aila 80W90 ma 140 rubles no 1 lita. ʻO kēia ke kumu kūʻai o nā lubricants home maʻalahi, no ka laʻana, ʻo OilRight brand. ʻO ke kumu kūʻai maʻamau e loli ma kahi o 300-400 rubles. ʻO ke kumukūʻai o nā huahana kiʻekiʻe a hiki i 1000 rubles i ka lita.
ʻO ka mana o ka home o ka aila 80W90 e like me ka papa inoa kahiko i kapa ʻia ʻo TAD-17, e like me ka mea hou - TM-4-18 (like me 80W90 GL-4) a i ʻole TM-5-18 (like me 80W90 GL-5) .
