Ma ka hana mechanical, he mea maʻamau ka hoʻohanaʻana i nā bearings, akā, aia mau kekahi poʻe e kuhihewa i kekahi mau pilikia i ka hoʻohanaʻana i nā bearings, e like me nā kuhi hewaʻekolu i hoʻokomoʻia ma lalo nei.
Manaʻo 1: ʻAʻole maʻamau nā bearings?
ʻO ka mea nāna e hoʻopuka i kēia nīnau he ʻike i ka bearings, akā ʻaʻole maʻalahi ka pane ʻana i kēia nīnau.Pono e ʻōlelo ʻia ʻo nā bearings nā ʻāpana maʻamau a ʻaʻole nā ʻāpana maʻamau.
ʻO keʻano, ka nui, ke kaha kiʻi, ka mākaʻikaʻi a me nā mea'ē aʻe o nā'āpana maʻamau i hoʻonohonoho ponoʻia.E pili ana i ka lawe ʻana o ke ʻano like, ka nui o ka nui like, me ka hoʻololi o ka hoʻonohonoho ʻana.
No ka laʻana, 608 bearings, kā lākou mau ana waho he 8mmx i loko anawaena 22mmx laula 7mm, ʻo ia hoʻi, nā bearings 608 i kūʻai ʻia ma SKF a me nā bearings 608 i kūʻai ʻia ma NSK ʻo ia ka nui o waho, ʻo ia hoʻi, he helehelena lōʻihi.
Ma kēia ʻano, ke ʻōlelo mākou he ʻāpana maʻamau ka bearing, pili wale ia i ke ʻano like a me ke poʻo.
ʻO ka manaʻo ʻelua: ʻaʻole ʻo nā bearings nā ʻāpana maʻamau.ʻO ka papa mua, ʻo ia hoʻi, no nā bearings 608, ua like ka nui o waho, ʻaʻole like ka loko!ʻO ka mea e hōʻoiaʻiʻo ai i ka hoʻohana ʻana i ka wā lōʻihi, ʻo ia nā ʻāpana kūkulu kūloko.
ʻO ka 608 bearings, hiki ke ʻano like ʻole ka loko.No ka laʻana, hiki ke hoʻomaʻemaʻe i ka MC1, MC2, MC3, MC4, a me MC5, ma muli o nā ʻae kūpono;Hiki ke hana ʻia nā pā i ka hao a i ʻole ka plastic;Hiki i ka pololei ke P0, P6, P5, P4 a pēlā aku e like me ke kumu o ke koho ʻana;Hiki ke koho ʻia ka momona mai ke kiʻekiʻe a hiki i ka haʻahaʻa haʻahaʻa i nā haneli mau ala e like me nā kūlana hana, a ʻokoʻa hoʻi ka nui o ka hoʻopaʻa ʻana i ka momona.
I kēia manaʻo, ʻōlelo mākou ʻaʻole ʻo ka bearing kahi ʻāpana maʻamau.Wahi a nā kūlana hana kūikawā, hiki iā ʻoe ke hāʻawi i nā hana like ʻole o 608 bearings no kāu koho.No ka hoʻohālikelike ʻana, pono ia e wehewehe i nā palena o ka lawe ʻana (ka nui, ke ʻano sealing, nā mea hale, ka ʻae, ka momona, ka nui o ka sila, etc.).
Ka hopena: No nā bearings, ʻaʻole pono ʻoe e noʻonoʻo iā lākou he mau ʻāpana maʻamau, pono mākou e hoʻomaopopo i ke ʻano o nā ʻāpana maʻamau, i mea e koho ai i nā bearings kūpono.
Myth 2: He 10 mau makahiki e hala ana kou hānau?
No ka laʻana, ke kūʻai aku ʻoe i kaʻa, kūʻai aku ka hale kūʻai 4S a haʻaheo ka mea hana i ka palapala hōʻoia no 3 mau makahiki a i ʻole 100,000 mau kilomita.Ma hope o ka hoʻohana ʻana iā ia no ka hapalua makahiki, ʻike ʻoe ua haki ke kaila a ʻimi i ka hale kūʻai 4S no ka uku.Eia naʻe, ʻōlelo ʻia ʻoe ʻaʻole i uhi ʻia e ka palapala hoʻokō.Ua kākau maopopo ʻia i loko o ka palapala hōʻoia ʻo ka palapala hōʻoia o 3 mau makahiki a i ʻole 100,000 mau kilomita he kūlana, a ʻo ka palapala hōʻoia no nā ʻāpana kumu o ke kaʻa (engine, gearbox, etc.).He ʻāpana ʻaʻahu kou kaʻa a ʻaʻole i loko o ke ʻano o ka hōʻoia.
Makemake au e hoʻomaopopo i nā makahiki 3 a i ʻole 100,000 mau kilomita āu i noi ai he kūlana.No laila, nīnau pinepine ʻoe "hiki i nā bearings ke hala 10 mau makahiki?"Aia kekahi mau kūlana.
ʻO ka pilikia āu e nīnau nei ʻo ke ola lawelawe o nā bearings.No ke ola lawelawe o nā bearings, pono ke ola lawelawe ma lalo o kekahi mau kūlana lawelawe.ʻAʻole hiki ke kamaʻilio e pili ana i ke ola lawelawe o nā bearings me ka ʻole o ka hoʻohana ʻana i nā kūlana.Pēlā nō, pono e hoʻololi ʻia kāu mau makahiki 10 i nā hola (h) e like me ke alapine hoʻohana kikoʻī o ka huahana, no ka mea, ʻaʻole hiki i ka helu ʻana o ke ola hānau ke helu i ka makahiki, ʻo ka helu wale nō o nā hola (H).
No laila, he aha nā kūlana e pono ai e helu i ke ola lawelawe o nā bearings?No ka helu ʻana i ke ola lawelawe o nā bearings, pono e ʻike i ka ikaika bearing (ka ikaika axial Fa a me ka ikaika radial Fr), ka wikiwiki (pehea ka wikiwiki o ka holo, ka holo ʻokoʻa a i ʻole ka holo wikiwiki ʻana), ka mahana (ka mahana ma ka hana).Inā he hāmama hāmama, pono ʻoe e ʻike i ka ʻaila lubricating e hoʻohana ai, pehea ka maʻemaʻe a pēlā aku.
Me kēia mau kūlana, pono mākou e helu i nā ola ʻelua.
Ola 1: ke ola helu kumu o ka lawe ʻana i ka L10 (e noʻonoʻo i ka lōʻihi o ka hiki ʻana mai o ka luhi ʻana o ka lawe ʻana)
Pono e hoʻomaopopo ʻia ʻo ke ola helu kumu o nā bearings ʻo ka nānā ʻana i ka hoʻomanawanui o nā bearings, a hāʻawi ʻia ke ola helu theoretical o 90% hilinaʻi.ʻAʻole lawa paha kēia ʻano kumu, no ka laʻana, hāʻawi ʻo SKF a i ʻole NSK iā ʻoe i nā coefficient hoʻoponopono like ʻole.
ʻO ke ola ʻelua: ʻo ke ola maʻamau o ka momona L50 (pehea ka lōʻihi o ka maloʻo ʻana o ka momona), ʻaʻole like ke ʻano helu helu o kēlā me kēia mea hana lawe.
ʻO ka lawe ʻana i ka momona momona L50 e hoʻoholo i ke ola hope o ka lawe ʻana, ʻaʻohe mea maikaʻi o ka maikaʻi, ʻaʻohe aila lubricating (maloʻo ka momona), pehea ka lōʻihi e hiki ai ke hoʻomaloʻo i ka friction friction?No laila, ʻo ka awelika o ka momona ola L50 ka mea i manaʻo ʻia ʻo ke ola lawelawe hope loa o ka bearing (nota: ʻo ka awelika o ka momona ola L50 ke ola i helu ʻia e ka empirical formula me ka hilinaʻi o 50%, ʻo ia wale nō no ka ʻike a loaʻa ka nui. discreteness i ka loiloi ho'āʻo maoli).
Ka hopena: Pehea ka lōʻihi o ka hiki ke hoʻohana ʻia e pili ana i nā kūlana maoli o ka bearing.
Manaʻo 3: He palupalu kou mau bearings a hāʻule lākou ma lalo o ke kaomi
He mea maʻalahi ka lawe ʻana i ke kaomi haʻahaʻa e loaʻa ka leo ʻino, e hōʻike ana i ka lawe ʻana i nā ʻili o loko, a laila, pehea ka hana ʻana o nā ʻōpala kūloko?
Ke hoʻokomo mau ʻia ka bearing, inā ʻo ke apo o loko ka ʻili o ka male, a laila e kaomi ʻia ke apo o loko, a ʻaʻole e hoʻoikaika ʻia ke apo o waho, a ʻaʻohe ʻōpala.
Akā, pehea inā, ma kahi o ka hana ʻana i kēlā, ua koʻikoʻi nā apo o loko a me waho e pili ana i kekahi i kekahi?Loaʻa kēia i kahi hōʻailona Brinell, e like me ka mea i hōʻike ʻia ma lalo nei.
ʻAe, heluhelu pololei ʻoe, he ʻoiaʻiʻo ʻino ia, inā ʻo ke apo o loko a me waho e pili ana i ke koʻikoʻi, he kaomi mālie wale nō, hiki ke maʻalahi ka lawe ʻana i ka indentation pōʻino ma ka ʻili o ka pōpō kila a me ka ʻili raceway, a laila hoʻopuka i ke kani kūlohelohe. .No laila, ʻo kēlā me kēia kūlana hoʻokomo i hiki ke hana i ke apo i loko a me waho e lawe i ka ikaika pili hiki ke hōʻeha i loko o ka bearing.
Ka hopena: I kēia manawa, ma kahi o 60% o ka lawe ʻana i ke kani ʻino ke kumu o ka lawe ʻana i ka pōʻino i hana ʻia e ka hoʻokomo pono ʻole.No laila, ma mua o ka hoʻāʻo ʻana e ʻimi i ka pilikia o ka lawe ʻana i nā mea hana, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ka ikaika ʻenehana o nā mea hana bear e hoʻāʻo ai i kā lākou kūlana hoʻonohonoho, inā he mau pilikia a me nā pōʻino huna.
