Na Lanai Papalua Cylindrical Roller Bearings

ʻO ka wehewehe pōkole:

He mau iwiʻaoʻao ma ka apo o loko a ʻaʻohe iwi ʻaoʻao ma ke apo o waho. Hiki ke hoʻokaʻawale ʻia ke apo o loko a me ka huila a me ka hale hale mai ke apo o waho. Hiki ke ʻae ʻia ke kumu e hana i ka neʻe ʻana axial ma nā ʻaoʻao ʻelua e pili ana i ka hale halihali, a lawe i nā ukana radial nui.

Nā bearings huila lālani ʻelua:
ʻAno NN: he iwi ʻaoʻao ke apo o loko, a ʻaʻohe iwi ʻaoʻao o ke apo o waho. Hiki ke hoʻokomo kaʻawale ka apo o waho a me ka hui i loko, ʻaʻole i kaupalena i ka neʻe ʻana o ka axial o ke kumu a i ʻole ka hale, a ʻaʻole hiki ke halihali i ka ukana axial. Ke hoʻohālikelike ʻia me ka lālani huila cylindrical hoʻokahi o ka nui radial like, hiki iā ia ke pale i nā ukana radial nui aʻe. Paʻa ka hale, liʻiliʻi ka deformation ma lalo o ka ukana, a kūpono loa ia no ke kākoʻo o ka spindle o ka mīkini mīkini.
ʻAno NN…K:
Ua like ka hale me ke ʻano NN, akā ua paʻi ʻia ka lua o loko o ka bearing, kahi kūpono no ka hoʻomaʻamaʻa maikaʻi ʻana i ka hoʻomaʻemaʻe radial o ka bearing a kūpono no ka hui ʻana a me ka wehe ʻana. Hoʻohana nui ʻia kēia ʻano o ka bearing ma ke kumu nui o ka mīkini mīkini a hoʻokomo ʻia ma ke kumu tapered. Hoʻoponopono ʻia ka hoʻomaʻemaʻe radial e ka nui kaomi o ke apo i loko.
Nā ʻano NNU, NNU…K:
He iwi ʻaoʻao ko ke apo o waho a ʻaʻohe iwi ʻaoʻao o ke apo o loko. ʻElua ʻano o nā puka cylindrical a me nā puka conical. ʻAʻole ia e kaupalena i ka neʻe ʻana o ke axial o ka lāʻau a i ʻole ka hale a ʻaʻole hiki ke halihali i nā ukana axial. Ke hoʻohālikelike ʻia me ka lālani huila cylindrical hoʻokahi o ka nui radial like, hiki iā ia ke pale i nā ukana radial nui aʻe.
ʻAno NNCF:
ʻEkolu iwi ʻaoʻao o ke apo o loko a ʻo ka apo i waho hoʻokahi iwi ʻaoʻao no ka hoʻonohonoho axial ma kahi ʻaoʻao. Hoʻokomo ʻia ke apo o waho me ke apo paʻa ma kekahi ʻaoʻao o ka iwi ʻaoʻao e mālama i ke apo i hoʻokahi ʻāpana.
ʻAno NNCL:
ʻEkolu iwi ʻaoʻao o ke apo o loko, ʻaʻohe iwi ʻaoʻao o ke apo o waho, a he mau apo pani ma nā ʻaoʻao ʻelua e lilo i mea hiki ke hoʻokaʻawale ʻia.
NNCS:
ʻEkolu mau iwi ʻaoʻao o ke apo o loko, ʻaʻohe iwi ʻaoʻao o ke apo o waho, a aia kekahi apo paʻa waena ma waena o ke apo o waho, a lilo ia i mea hiki ke hoʻokaʻawale ʻia. ʻO ka lāʻau a me ka noho ʻana e ʻae i kahi neʻe axial a hiki ke hoʻohana ʻia ma ke ʻano he hopena manuahi.

Nā noi

Hoʻohana nui ʻia ia mau bearings i nā mīkini mea hana spindles, nā ʻenekini hoʻopau i loko, nā turbines gas, nā mea hoʻemi, ka hoʻouka ʻana a me ka wehe ʻana i nā mīkini a me nā mīkini ʻenehana like ʻole.

Laulā nui:

Nā bearings huila lālani ʻelua:

Ka nui anawaena o loko: 50mm~1500mm
Ka nui anawaena o waho: 80mm~2300mm
Laulā nui laula: 23mm~800mm

 

ʻO ka hoʻomanawanui: ʻO ka pololei o ka huahana he papa maʻamau, P6 grade, P5 grade, a me nā huahana P4 grade hiki ke hana ʻia inā loaʻa i ka mea hoʻohana nā koi kūikawā.
Hoʻomaʻemaʻe Radial
ʻO ka huahana maʻamau o ka lālani ʻelua cylindrical roller bearing he 1 set of clearance, a hiki i ka cylindrical bore bearings ke hāʻawi pū i 2 a i ʻole 3 sets of clearance.
Loaʻa pū ʻia nā bearings tapered me nā ʻāpana 2 o ka hoʻomaʻemaʻe.
Hiki ke hana ʻia nā bearings me ka radial clearance e like me nā koi o ka mea hoʻohana.
