Hoʻomaʻamaʻa Wela
ʻO ka hoʻomaʻamaʻa wela e pili ana i ke ʻano hana wela pālua o ke kinai ʻana a me ka wela wela kiʻekiʻe.ʻO kāna kumu e hana i ka mea hana i nā waiwai mechanical piha maikaʻi.ʻO ka hoʻonā wela kiʻekiʻe e pili ana i ka hoʻoulu ʻana ma 500-650 ℃.ʻO ka hapa nui o nā ʻāpana wela e hana ma lalo o ka hana o ka haʻahaʻa ikaika nui.Lawe lākou i nā hopena o ka ʻāʻī, ka hoʻopaʻa ʻana, ke kuʻi ʻana, ka torsion a i ʻole ke ʻoki ʻana.He friction kekahi o nā ʻili, kahi e pono ai ke pale ʻana i ka ʻaʻahu.I ka pōkole, hana nā ʻāpana ma lalo o nā koʻikoʻi hui like ʻole.ʻO kēia ʻano ʻāpana ka hapa nui o nā mīkini like ʻole a me nā mīkini, e like me nā shafts, connecting rods, studs, gears, etc., i hoʻohana nui ʻia i nā mea mīkini, nā kaʻa, nā trak a me nā ʻoihana hana ʻē aʻe.ʻOi aku no nā ʻāpana nui i ka hana ʻana i nā mīkini kaumaha, hoʻohana ʻia ka mālama wela.No laila, he mea koʻikoʻi ka mālama ʻana i ka wela i ka mālama wela.I nā huahana mechanical, ma muli o nā kūlana koʻikoʻi like ʻole, ʻaʻole like ka hana i koi ʻia.ʻO ka ʻōlelo maʻamau, ʻo nā ʻano ʻāpana wela a pau e loaʻa nā waiwai mechanical piha piha, ʻo ia hoʻi, ka hui kūpono o ka ikaika kiʻekiʻe a me ka paʻakikī kiʻekiʻe e hōʻoia i ka hana maʻalahi o nā ʻāpana.
ʻO ka mālama wela o ka paipu kila kekahi o nā kaʻina hana nui i ka hana mechanical.Ke hoʻohālikelike ʻia me nā ʻenehana hana ʻē aʻe, ʻaʻole hoʻololi ka mālama wela i ke ʻano a me ka hoʻohui kemika o ka mea hana holoʻokoʻa, akā hāʻawi a hoʻomaikaʻi paha i ka hana o ka mea hana ma o ka hoʻololi ʻana i ka microstructure kūloko a i ʻole ka hoʻohui ʻana o ka ʻili mea hana.ʻO kāna hiʻohiʻona ka hoʻomaikaʻi ʻana i ka maikaʻi o loko o ka mea hana, ʻaʻole i ʻike ʻia e ka maka ʻōlohelohe.I mea e loaʻa ai i ka paipu kila ka pono mechanical, physical and chemical properties, pono pinepine ke kaʻina hana wela me ka hoʻohui i ke koho kūpono o nā mea a me nā kaʻina hana like ʻole.ʻO ke kila ka mea i hoʻohana nui ʻia i ka ʻoihana mechanical.He paʻakikī ka microstructure o ke kila a hiki ke mālama ʻia e ka mālama wela.Eia kekahi, hiki ke hoʻololi ʻia nā ʻano mechanical, physical a me kemika o ka aluminika, ke keleawe, ka magnesium, ka titanium a me kā lākou mau ʻāpana e ka mālama wela e loaʻa ai nā ʻano lawelawe lawelawe like ʻole.
