ʻO ke kumu kūpono o ke koho ʻana i ka ʻae ʻana o ka bearing motor

ʻO nā huahana kaʻa me nā bearings, ma muli o ke kuleana o nā ʻāpana pili, ma ke kuhikuhi radial a me ke axial e pili ana i nā palena hoʻonoho, ʻo ka hopena hope loa e loaʻa ka hopena i ka ʻae ʻana o ka bearing, kahi i hōʻike ʻia ma ka ʻae mua o ka bearing a me ka ʻokoʻa ma waena o kaka ʻae hana.

ʻO ke kaʻawale i loko o kahi bearing ka mamao holoʻokoʻa e hiki ai i kekahi o nā apo bearing ke neʻe ma ke kuhikuhi radial a i ʻole axial e pili ana i ke apo bearing ʻē aʻe. E pili ana i ke kaʻawale o kahi bearing, pono e hana i kahi ʻokoʻa ma waena o ke kaʻawale ma mua o ke kau ʻana a me ke kaʻawale ma hope o ke kau ʻana a me ka hiki ʻana i kona mahana hana. ʻOi aku ka liʻiliʻi o ka kaʻawale hana o kahi bearing ma mua o ka kaʻawale mua ma muli o nā kūpono hoʻomanawanui me nā nui like ʻole o ka hoʻopilikia a me nā kekelē like ʻole o ka hoʻonui wela o nā apo bearing a me nā ʻāpana pili (e like me nā ʻau motika, nā pāpale hope, a pēlā aku), e hopena ana i ka hoʻonui ʻana a i ʻole ke kaomi ʻana o ke apo.

Nā loina laulā o ka kaohi a me ka haku: ʻO ka ʻae hana o nā bearings pōpō he ʻole a i ʻole he preload iki. Eia nō naʻe, no ka wili cylindrical, ka wili spherical a me nā bearings ʻē aʻe, pono e loaʻa kahi koena ʻae i ka hana, ʻoiai inā he liʻiliʻi loa ia.

Ma keʻano laulā ma lalo o nā kūlana hana maʻamau, hiki ke loaʻa kahi ʻae hana kūpono ma ke koho ʻana i nā bearings me kahi ʻae hui maʻamau. Eia naʻe, i ka wā o kanā kūlana hana a me ke kau ʻanaʻokoʻa ke kūlana maʻamau, e like me ke kūpono o ke komo ʻana o nā bearings o nā apo ʻelua, a i ʻole he mana nui ka ʻokoʻa o ka mahana o ke apo, a laila pono e koho ʻia ka ʻae ʻana ma mua o ka hui maʻamau o nā bearings nui a liʻiliʻi paha.

Ma muli o ke noi, pono e hoʻonohonoho ʻia nā bearings me ka ʻae hana maikaʻi a maikaʻi ʻole paha. I ka hapanui o nā hihia, pono ka ʻae hana e maikaʻi, ʻo ia hoʻi, pono e hana ka bearing me kahi nui o ke koena. Ma ka ʻaoʻao ʻē aʻe, he nui nā noi kahi e pono ai ka ʻae hana maikaʻi ʻole - ʻo ia hoʻi ka preload.

Hiki ke hoʻohana ʻia ka hoʻouka mua ʻana o nā bearings e hoʻonui i ka paʻakikī a i ʻole ka pololei o ka wili ʻana o nā hoʻonohonoho bearing. ʻO nā laʻana e komo pū me nā bearing spindle i nā mea hana mīkini, nā bearing pinion i nā driveshafts automotive, nā bearings i nā motika liʻiliʻi, a i ʻole nā ​​​​hoʻonohonoho bearing no ka neʻe reciprocating. I kekahi mau noi kahi ʻaʻole i kau ʻia nā bearings, a i ʻole wale nō, i nā ukana liʻiliʻi loa a hoʻohana ʻia i nā wikiwiki kiʻekiʻe, pono e hoʻopili ʻia ka preload i kahoʻonohonoho ʻana o ka bearingI kēia hihia, ʻo ke kumu o ka preload ʻo ia ka hāʻawi ʻana i kahi ukana liʻiliʻi loa i ka bearing e pale aku i nā mea ʻōwili mai ka paheʻe ʻana a me ka hōʻino ʻana i ka bearing.

Hiki i ka preload ke radial a i ʻole axial ma muli o ke ʻano o ka bearing. ʻO nā bearings wili cylindrical, no ka laʻana, hiki ke hoʻopili wale ʻia ka preload ma ke kuhikuhi radial ma muli o kā lākou hoʻolālā, ʻoiai ʻo nā bearings pōpō thrust a me nā bearings wili cylindrical hiki ke hoʻopili wale ʻia ka preload ma ke kuhikuhi axial. ʻO nā bearings pōpō hoʻopili angular hoʻokahi lālani a me nā bearings wili tapered e kau pinepine ʻia i ka axial preload a hoʻohana pinepine ʻia i nā hui hope-i-hope a i ʻole ke alo-i-maka me kekahi bearing o ke ʻano like. Hoʻopili pinepine ʻia nā bearings pōpō groove hohonu me ka preload axial like, i mea e hoʻokō ai i ke kumu o ka preload, pono e hoʻohana ʻia me kahi hui ʻoi aku ka nui ma mua o ka maʻamau o ka radial internal clearance, i hiki ai ke like me nā bearings pōpō hoʻopili angular he kihi hoʻopili ʻoi aku ka nui ma mua o ka zero.
