Hāpaiʻo ia kekahi o nā ʻāpana mechanical i hoʻohana pinepine ʻia, e halihali ana i ka ʻōwili a me ka neʻe ʻana o ke kumu, i maʻalahi ka neʻe ʻana o ke kumu a kākoʻo iā ia. Inā hoʻohana ʻia nā bearings, hiki ke hoʻemi ʻia ka friction a me ka ʻaʻahu. Ma ka ʻaoʻao ʻē aʻe, inā haʻahaʻa ka maikaʻi o ka bearing, e hoʻopau ʻia ka mīkini, no laila ua manaʻo ʻia ka bearing kekahi o nā ʻāpana mechanical koʻikoʻi.

ʻElua ʻano nui o nā bearings: sliding bearings anā huila ʻōwili.

Piʻi maʻamau:

Hoʻokumu ʻia nā bearings paʻa i kahi noho a me kahi kumu lāʻau. I nā bearings maʻamau, pili pololei ka lāʻau me ka ʻili o ka bearings. Hiki iā ia ke pale i ka wikiwiki kiʻekiʻe a me ka ukana hopena. Hoʻohana ʻia nā bearings i nā ʻenekini o nā kaʻa, nā moku a me nā mīkini.

ʻO ia ka ʻaila kiʻiʻoniʻoni e kākoʻo ana i ka hoʻololi ʻana. ʻO kahi kiʻiʻaila he kiʻi lahilahi o kaʻaila. Ke piʻi ka wela o ka aila a i ʻole ke kaumaha nui ʻana, e lahilahi ka ʻaila kiʻiʻoniʻoni, e hoʻopili ai i ka metala a e ʻā ana.

ʻO nā hiʻohiʻona ʻē aʻe he:

1. He nui ka ukana i ʻae ʻia, liʻiliʻi ka haʻalulu a me ka walaʻau, a hiki ke noho mālie ka hana.

2. Ma ka hana ʻana i ka lubrication state a me ka mālama ʻana, hiki ke hoʻohana ʻia ke ola lawelawe semi-permanently.

Piʻi ʻōwili：

Hoʻolako ʻia nā bearings rolling me ka pōpō a i ʻole ka wili (paʻa puni) e hōʻemi i ka pale ʻana i ka friction. ʻO nā bearings kaʻa: nā bearings pōleʻa hohonu, nā bearings ball contact angular, tapered roller bearings, thrust bearings, etc.

ʻO nā hiʻohiʻona ʻē aʻe he:

1. Haʻahaʻa hoʻomaka friction.

2. Ke hoʻohālikelike ʻia me nā bearings sliding, ʻoi aku ka liʻiliʻi o ka friction.

3. No ka mea ua hoʻohālikelike ka nui a me ka pololei, ua maʻalahi lākou e kūʻai.

I ka hopena, ʻo nā bearings kekahi o nā ʻāpana maʻamau (mau ʻāpana maʻamau) i ka hoʻolālā mechanical. ʻO ka hoʻohana maikaʻi ʻana i nā bearings hiki ke hoʻomaikaʻi i ka hana o nā huahana a hoʻemi i nā kumukūʻai, no laila he mea koʻikoʻi ke aʻo i ka ʻike kūpono o nā bearings.
