Ka hoʻohālikelike ʻana ma waena o nā bearings pōpō a me nā bearings roller
ʻO ka ʻokoʻa nui ma waena Ka hali ʻana o ka pōpōʻO nā bearings s a me nā roller bearings ke ʻano a me ke ʻano pili o ka element rolling, ka mea e hoʻopilikia pololei i kā lākou hana a me nā hiʻohiʻona noi.
ʻAno a me ke kumumanaʻo hana
Ka hali ʻana o ka pōpō:
He poepoe nā ʻāpana ʻōwili o kahi bearing pōpō a ʻo ka pili ʻana me nā raceways he pili kiko. I ka piʻi ʻana o ka ukana, lilo ke kiko pili i wahi elliptical, e hāʻawi ana i nā bearing pōpō i ka pale ʻana i ka frictional a me ka emi ʻana o ka hana wela i ka wā e wili ana i ka wikiwiki kiʻekiʻe, kūpono no nā hiʻohiʻona wili wikiwiki kiʻekiʻe.
He ʻano cylindrical a conical paha nā ʻāpana ʻōwili o kahi bearing roller, a ʻo ka pili ʻana me nā raceways he pili laina. Hiki i ka wahi pili nui ke hoʻopuehu i ka ukana nui aʻe, no laila ʻoi aku ka nui o ka hiki ke hāpai, akā ʻoi aku ka nui o ke kū'ē ʻana i ka friction, kūpono no ka ukana kaumaha akā haʻahaʻa ka wikiwiki o ka wili.
Nā ʻano hana
Ka hali ʻana o ka pōpō:
Nā Pōmaikaʻi: Haʻahaʻa ka haʻalulu hoʻomaka, ka haʻalulu hana kūpono, hiki ke kū i nā ukana radial a me axial i hui pū ʻia, ʻaʻole pili i ka hoʻopau ʻana o ka lubrication, maʻalahi e hoʻomaka ma nā mahana haʻahaʻa.
Nā hemahema: Ke kūpaʻa haʻalulu maikaʻi ʻole, ka ʻae radial nui, ka mea e hoʻonui ai i ka haʻalulu a me ka walaʻau.
ʻO ka mea hāpai wili:
Nā Pōmaikaʻi: Ka hiki ke hāpai ikaika, ka pololei o ka hana, ke ʻano paʻa, ke kumu kūʻai haʻahaʻa.
Nā Pōʻino: Ke kūpaʻa hopena maikaʻi ʻole, hoʻemi ʻia ke ola ma lalo o nā kūlana wikiwiki a me nā ukana kaumaha, nā apo kūloko a me waho i hoʻohui ʻia, paʻakikī ke hoʻouka.
Nā hiʻohiʻona noi
Nā mea hoʻopaʻa pōpō:
Kūpono no nā noi e pono ai ka wikiwiki kiʻekiʻe, ka ukana liʻiliʻi a me ka hoʻokele waiwai maikaʻi, e like me nā motika, nā peʻahi, a pēlā aku.
Nā mea hoʻopaʻa wili:
Kūpono no nā noi me ka wikiwiki wili haʻahaʻa, nā ukana nui a i ʻole nā ukana hopena, e like me nā mīkini kaumaha, nā kaʻa, ke kaʻaahi, a pēlā aku.
ʻO wai ka mea i ʻoi aku ka nui o ka hiki ke hāpai i nā ukana, nā bearings pōpō a i ʻole nā bearings rollerʻAʻole anei?
Ma ke ʻano o ka hana hāpai ukana, aia nā ʻokoʻa koʻikoʻi ma waena o nā bearings roller a me nā bearings pōpō. ʻO nā bearings roller, me ko lākou ʻano paʻa i haku ʻia me nā apo o loko, nā apo o waho, nā rollers a me nā cages, hōʻike i ka hiki ke hāpai ukana koʻikoʻi. Hana maikaʻi lākou ma lalo o nā ukana radial kiʻekiʻe a me nā ukana radial māmā a waena, e lilo ana iā lākou i koho kūpono no nā mīkini a me nā lako hana kaumaha a me nā mea hana kaumaha loa, e like me nā mīkini kaumaha, nā mīkini kūkulu hale a me nā pahu pahu nui. I ka hoʻohālikelike ʻana, ʻoiai he ʻano maʻalahi nā bearings pōpō, pololei kiʻekiʻe a me ka haʻalulu haʻahaʻa, ʻoi aku ka haʻahaʻa o ko lākou hiki ke hāpai ukana a ʻoi aku ka kūpono no nā kūlana ukana waena. Hoʻokomo pū nā bearings pōpō i nā ʻano like ʻole e like me nā bearings pōpō groove hohonu, nā bearings pōpō hoʻopili angular a me nā bearings pōpō hoʻonohonoho ponoʻī, kūpono kēlā me kēia no nā lako me nā koi wikiwiki a me nā ukana like ʻole. No laila, i ke koho ʻana i ke ʻano o ka bearing, pono e noʻonoʻo pono ʻia ma muli o nā kūlana ukana kikoʻī a me ke kaiapuni hoʻohana o nā lako mīkini. ʻOi aku ka kūpono o nā bearings roller no ke kū ʻana i nā ukana radial nui a me nā ukana kaumaha, ʻoiai ʻoi aku ka maikaʻi o ka hana ʻana o nā bearings pōpō ma lalo o nā ukana kaulike.
He aha nā pōmaikaʻi a me nā pōʻino o nā bearings roller a me nā bearings ball?
Loaʻa i nā bearings wili a me nā bearings pōpō ko lākou mau pono a me nā hemahema. Loaʻa i nā bearings wili kahi wahi pili nui me nā raceways no ka mea he cylindrical nā mea wili, kahi e hiki ai iā lākou ke kū i nā ukana radial koʻikoʻi. Loaʻa iā lākou ke kūpaʻa maikaʻi a me ka lōʻihi i ka wā o ka hana wikiwiki, akā he nui ko lākou coefficient friction. He poepoe nā mea wili o nā bearings pōpō, me kahi coefficient haʻahaʻa o ka friction a me ka hana maʻalahi. He kūpono lākou no nā noi e pono ai ka pololei kiʻekiʻe a me ka hana wikiwiki. Eia nō naʻe, i ka wā e kau ʻia ai i nā ukana kaumaha, hiki iā lākou ke hana i ka pilina paʻa ʻole ma muli o ka hopena o ka ikaika centrifugal. ʻO ke ʻano o ka bearing e koho ai e pili pono ana i kāu hiʻohiʻona noi maoli a me nā koi.
ʻO wai ka mea kūpono no ka hana wikiwiki, nā bearings roller a i ʻole nā bearings ball?
ʻOi aku ka maikaʻi o nā bearings roller no ka hana wikiwiki. Loaʻa i nā bearings roller nā mea ʻōwili cylindrical, kahi e hopena ai i kahi wahi pili nui me nā raceways. Hiki iā lākou ke kū i nā ukana kaumaha a loaʻa ke kūpaʻa maikaʻi a me ka lōʻihi i ka wā o ka hana wikiwiki. He poepoe nā mea ʻōwili o nā bearings pōpō. ʻOiai he liʻiliʻi ka coefficient o ka friction, i ka wā o ka hana wikiwiki, hiki i ka pilina ma waena o nā pōpō a me nā raceways ke lilo i mea paʻa ʻole ma muli o ka hopena o ka ikaika centrifugal. ʻOiaʻiʻo, pono e hoʻoholo ʻia ke koho kikoʻī o ka bearing e hoʻohana ai ma muli o kāu hiʻohiʻona noi maoli a me nā koi.
