Kaomi-15 a i ʻole Tad-17. He aha ka mānoanoa? Nā ʻokoʻa

Tap-15 a i ʻole Tad-17: ʻokoʻa

Tap-15 a i ʻole Tad-17? Inā mākou e noʻonoʻo i ke ʻano kemika o kēia mau lubricants, a laila liʻiliʻi nā ʻokoʻa. Loaʻa nā mea ʻelua i ka mineral, ʻoiai ua hana ʻia lākou i ke kaʻina o ka distillation a me ka distillation o kekahi mau māka o ka aila. ʻOi aku ka liʻiliʻi o Tep-15, a no laila ua hoʻemi ʻia ka neʻe ʻana o ke kaomi nui a me nā mea hoʻohui antiwear ma laila. Eia kekahi, ʻoi aku ka haʻahaʻa o ka viscosity o Tep-15, ʻoiai no ka nui o nā wahi neʻe o nā kaʻa (ʻoi aku ka hana o ka home), ʻaʻole koʻikoʻi kēia hōʻailona.

ʻO ka palekana o ka hoʻohana ʻana i nā lubricants e noʻonoʻo ʻia ʻaʻole wale i ka ikaika o ko lākou mānoanoa i nā haʻahaʻa haʻahaʻa (no Tad-17, ʻo ka pae wela hana ʻo -20 a +135.^ºC, a no Tep-15 mai -23 a +130^ºC), akā ʻo ke kiʻekiʻe hoʻi o ka hoʻopaʻapaʻa kemika e pili ana i nā sila pahu pahu. Ma kēia ʻano, ʻoi aku ka ikaika o Tad-17. Loaʻa iā ia ka sulfur a me ka phosphorus i ka nui o ka nui, e kōkua ana i nā hopena mechanochemical ma ka ʻili o nā ʻāpana hypoid gear. Ma muli o ia mau hopena, hoʻokumu ʻia nā kiʻiʻoniʻoni ma laila e hoʻonui ai i ka mana anti-seize o ka mea ma lalo o nā kūlana o ka wikiwiki sliding kiʻekiʻe o hoʻokahi mea hoʻouna ma luna o kahi mea pili. Ma lalo o ia mau kūlana, ʻaʻole i lawa ka pale ʻana i ka ʻaʻahu ʻana i nā hōʻailona o nā hōʻailona lāʻau. Eia kekahi, inā hana ʻia ka synchronizer i ke keleawe a i ʻole ke keleawe keleawe, a laila e hoʻemi ʻia kona kūʻē.

ʻO ka mea ʻē aʻe, ʻo Tep-15, ʻaʻole i loaʻa ka nui o nā reagents chemically active, ʻoi aku ka liʻiliʻi o ke kiʻekiʻe o ka pale ʻana i ka aila o ka lāʻau a me ke ʻano o nā ʻāpana keleawe.

He aha ka mānoanoa - Tap-15 a i ʻole Tad-17?

Ke hoʻohālikelike nei, he mea nui e loiloi ʻaʻole wale i ka waiwai piha o ka viscosity, akā ʻo kona hoʻololi ʻana i ke kaʻina o ka hoʻonui ʻana i ka mahana.

ʻO ka aila brand Tep-15 e like me GOST 17479.2-85 no nā ʻaila o ka hui 2nd, aia wale nō nā mea hoʻohui antiwear, a no laila ua hoʻolālā ʻia no ka hoʻohana pono ʻana ma lalo o nā ukana waho a hiki i 2 GPa a me nā mahana nui a hiki i 130^ºC. I ka manawa like, ua komo pū ʻo Tad-17 i nā mea hoʻohui koʻikoʻi, a no ka hui 5, no ka mea, hiki i nā haʻahaʻa waho ma nā shafts a me nā gears ke hiki i 3 GPa a ʻoi aku paha, ma ka nui o nā mahana a hiki i 150.^ºH.

No laila, ʻo nā ʻāpana maikaʻi loa no ka hoʻohana ʻana iā Tep-15 he cylindrical, bevel a - ʻāpana - nā ʻōpala ilo, e hana ana ma nā haʻahaʻa haʻahaʻa haʻahaʻa, a no Tad-17 - ka nui o ka hypoid gears, kahi e hiki ai ia mau wikiwiki i 5 ... 7 % o ka lua o ka māmā holo kaʻa. No laila, piʻi ka mea hōʻike lole i ia mau kūlana mai 0,4 a 0,5.

ʻO ka loiloi o ka paʻa o nā hōʻailona viscosity e pili ana i ka mahana o ka leo o ka node e hāʻawi i kēia mau waiwai. No Tep-15, hoʻololi ka viscosity penei:

• Ma ka 100^ºC - 15… 16 mm²/ s.
• Ma ka 50^ºC - 100… 120 mm²/ s.
• Ma ka 20^ºC - 870… 1150 mm²/ s.

No laila, ʻo nā hōʻailona like no Tad-17:

• Ma ka 100^ºC - 18… 20 mm²/ s.
• Ma ka 50^ºC - 180… 220 mm²/ s.
• Ma ka 20^ºC - 1500… 1600 mm²/ s.

Hoʻokahi like, Tap-15 a i ʻole Tad-17? Ke hoʻohālikelike nei i ka hana o nā lubricants, manaʻo mākou ʻoi aku ka kiʻekiʻe o ka ukana o Tad-17 gear oil, no laila, hiki ke hoʻohana ʻia i nā ukana i hoʻonui ʻia ma ka mīkini, kahi e noho lōʻihi ai kahi kiʻiʻoniʻoni ʻaila e hoʻokaʻawale ana i nā ʻāpana. kauoha. I ka manawa like, ʻoi aku ka maikaʻi o Tep-15 no ka hoʻohana ʻana i nā pahu pahu tractor, a me nā kaʻa kaʻa medium-duty.
