ʻO nā bearings, he ʻāpana koʻikoʻi a koʻikoʻi o nā huahana mechanical, he kuleana koʻikoʻi i ke kākoʻo ʻana i ke kumu wili.E like me nā ʻano friction ʻokoʻa i loko o ka bearing, ua māhele ʻia ka bearing i ka bear friction rolling (i kapa ʻia ʻo rolling bearing) a me ka sliding friction bearing (i kapa ʻia ʻo sliding bearing).Loaʻa i nā ʻano bearings ʻelua ko lākou mau hiʻohiʻona i ka hoʻolālā a me nā pono a me nā hemahema i ka hana.

1. Ka hoʻohālikelike o nā huila ʻōwili a me nā bearings sliding

1. Hoʻohālikelike i ke ʻano hana a me ke ʻano neʻe

ʻO ka ʻokoʻa loa ma waena o nā bearings rolling a me nā bearings maʻamau ʻo ia ka hele ʻana a i ʻole ka ʻole o nā mea ʻōwili.

(1) Loaʻa i nā bearings nā mea ʻōwili (nā pōpō, nā ʻōwili cylindrical, nā ʻōwili tapered, nā wili nila), ka mea e hoʻohuli e kākoʻo i ke kumu ʻōwili, no laila ʻo ka ʻāpana hoʻopili he kiko, ʻoi aku ka nui o nā mea ʻōwili, ʻoi aku ka nui o nā helu pili.

(2) ʻAʻohe mea ʻōwili o ka bearing sliding, a ua kākoʻo ʻia ka lāʻau wili e ka ʻili maʻemaʻe, no laila he ʻili ka ʻāpana pili. ʻO ka ʻokoʻa o ka hoʻolālā ma waena o nā mea ʻelua e hoʻoholo ai i ka ʻōwili ʻana o ka neʻe ʻana o ka bearing, a ke hoʻoheheʻe nei ke ʻano o ka neʻe ʻana o ka bearing sliding, no laila ʻokoʻa loa ke kūlana friction.

2. Hoʻohālikelike i ka hiki ke lawe

ʻO ka ʻōlelo maʻamau, ma muli o ka nui o ke kaomi ʻana o nā bearings sliding, ʻoi aku ka kiʻekiʻe o ka hiki ʻana o nā bearings sliding ma mua o nā bearings rolling, a ʻaʻole kiʻekiʻe ka hiki o nā bearings rolling e kū i nā ukana hopena, akā ʻo nā bearings lubricated piha. hiki ke pale aku i nā ukana haʻalulu nui.Ke kiʻekiʻe ka wikiwiki o ka hoʻololi ʻana, piʻi ka ikaika centrifugal o nā mea ʻōwili i loko o ka ʻōwili wili, a pono e hoʻemi ʻia kona hiki ke lawe (no ka leo e hiki mai i ka wikiwiki kiʻekiʻe).No nā bearings sliding hydrodynamic, piʻi ka hiki ke lawe i ka ukana i ka piʻi ʻana o ka wikiwiki.

3. Ka hoʻohālikelike o ka friction coefficient a me ka hoʻomaka frictional kū'ē

Ma lalo o nā kūlana hana maʻamau, ʻoi aku ka haʻahaʻa o ka friction coefficient o nā bearings rolling ma mua o nā bearings sliding, a paʻa ka waiwai.Hoʻopili maʻalahi ka lubrication o nā bearing sliding e nā mea o waho e like me ka wikiwiki o ka rotational a me ka vibration, a ʻokoʻa ke ʻano o ka friction coefficient.

I ka hoʻomaka ʻana, no ka mea ʻaʻole i hoʻokumu ʻia ka ʻili ʻaila paʻa, ʻoi aku ka nui o ke kūpaʻa ma mua o ka ʻōwili ʻana, akā liʻiliʻi loa ke kūʻē frictional hoʻomaka a me ka coefficient friction hana o ka hydrostatic sliding bearing.

4. Hoʻohālikelike ka wikiwiki hana kūpono

Ma muli o ka palena o ka ikaika centrifugal o nā mea ʻōwili a me ka piʻi ʻana o ka mahana o ka bearing, ʻaʻole hiki ke hoʻololi i ka bearing rolling kiʻekiʻe loa, a he kūpono ia no nā kūlana hana wikiwiki a haʻahaʻa.Ma muli o ka wela a me ka ʻaʻahu o ka bearing, ʻaʻole pono e kiʻekiʻe ka wikiwiki o ka hana ʻana o ka bearing lubricated wai piha ʻole.He maikaʻi loa ka hana kiʻekiʻe o ka bearing wai-lubricated piha, ʻoi aku ka maikaʻi o ka hoʻohana ʻana o ka hydrostatic sliding bearing e like me ka lubricant, hiki i kona wikiwiki ke hiki i 100000r / min.

5. Hoʻohālikelike i ka nalowale o ka mana

Ma muli o ka liʻiliʻi liʻiliʻi liʻiliʻi o nā bearings rolling, ʻaʻole nui ka mana o ka mana, ʻoi aku ka liʻiliʻi ma mua o nā bearings lubricated wai piha ʻole, akā e hoʻonui nui ʻia ke kūpono ʻole ka lubrication a me ka hoʻonohonoho ʻana.ʻOi aku ka haʻahaʻa o ka mana friction o nā bearings lubricated wai piha, akā no nā bearings sliding hydrostatic, ʻoi aku ka nui o ka pau ʻana o ka mana ma mua o nā bearings hydrodynamic sliding ma muli o ka nalowale o ka mana o ka paila aila.

6. Hoʻohālikelike i ke ola lawelawe

Ma muli o ka mana o ka luawai waiwai a me ka luhi, ua hoʻolālā ʻia nā bearings rolling no 5 a 10 mau makahiki, a i ʻole ke hoʻololi ʻia i ka wā o ka overhaul.ʻO nā pad bearing o nā bearing lubricated wai piha ʻole ua ʻeha loa a pono e hoʻololi pinepine ʻia.ʻO ke ola o kahi bearing lubricated wai piha i ka manaʻo ʻole, akā i ka hoʻomaʻamaʻa ʻana, ma muli o nā pōʻai koʻikoʻi, ʻoi aku hoʻi no nā bearings sliding hydrodynamic, hiki i ka mea pad pad ke loaʻa ka luhi luhi.

7. Hoʻohālikelike i ka pololei o ka hoʻololi ʻana

Ma muli o ka liʻiliʻi o ka radial clearance o nā bearings rolling, ʻoi aku ka kiʻekiʻe o ka pololei o ka rotation.ʻO nā bearings lubricated wai piha ʻole i ka mokuʻāina o ka lubrication palena a i ʻole ka lubrication hui ʻia, a paʻa ʻole ka hana, koʻikoʻi ka lole, a haʻahaʻa ka pololei.Loaʻa i nā bearings lubricated wai piha i ka precision kiʻekiʻe ma muli o ke alo o ka ʻaila kiʻiʻoniʻoni, buffering a me ka haʻalulu haʻalulu.ʻOi aku ka pololei o ka hoʻololi ʻana i ka bearing hydrostatic.

8. Hoʻohālikelike ma nā ʻano ʻē aʻe

Hoʻohana ʻia ka ʻaila ʻaila, ka momona a i ʻole ka lubricant paʻa. He liʻiliʻi loa ka dosage, a he nui ka dosage i ka wikiwiki kiʻekiʻe. Pono e kiʻekiʻe ka maʻemaʻe o ka ʻaila, no laila pono e hoʻopaʻa ʻia, akā maʻalahi ke hoʻololi ʻana i ka bearing a ʻaʻole pono e hoʻoponopono i ka puke pai.

No nā bearings sliding, koe wale no nā bearings incompletely lubricated, ʻo ka lubricant ka wai a i ʻole ke kinoea, a nui ka nui, a pono pū ka maʻemaʻe o ka ʻaila. Pono e hoʻololi pinepine ʻia ka lāʻau bearing, a i kekahi manawa e hoʻoponopono ʻia ka puke pai.

2. Ke koho ʻana i nā bearings rolling a me nā sliding bearings

Ma muli o ka paʻakikī a me ka ʻokoʻa o nā kūlana hana maoli, ʻaʻohe maʻamau i hui pū ʻia no ke koho ʻana i nā bearings rolling a me nā sliding bearings.Ma muli o ka liʻiliʻi friction coefficient, haʻahaʻa hoʻomaka kū'ē, sensitivity, kiʻekiʻe ka pono, a me ka standardized, rolling bearings i maikaʻi interchangeability a me versatility, a ua maʻalahi e hoʻohana, lubricate a mālama. hoʻohana nui ʻia.

He mau pono kūʻokoʻa ka sliding bearings, a hoʻohana maʻamau i kekahi mau manawa i hiki ʻole ai, kūpono ʻole a i ʻole nā ​​​​pono e hoʻohana i nā bearings rolling, e like me kēia mau manawa:

1. Ua kaupalena ʻia ka nui o ka radial space, a i ʻole e hoʻokaʻawale a hoʻokomo ʻia ka manawa

Ma muli o ke apo o loko, ke apo o waho, ka ʻōwili kino a me ka hale i loko o ke ʻano o ka ʻōwili ʻana, nui ka nui o ka radial, a ua kaupalena ʻia ka noi.Ke koʻikoʻi nā koi o ka nui o ka radial, hiki ke koho i nā bearings roller. I ka wā e pono ai, pono e koho i nā bearings sliding.No nā bearings i kūpono ʻole, a ʻaʻole hiki ke hoʻokomo ʻia mai ke kuhikuhi axial, a me nā ʻāpana pono e hoʻokomo ʻokoʻa, hoʻohana ʻia nā bearings sliding.

2. Nā manawa kūpono kiʻekiʻe

Ke hoʻohana ʻia nā bearings i nā koi kikoʻī kiʻekiʻe, koho ʻia nā bearings sliding, no ka mea, hiki i ka lubricating oil film o nā sliding bearings ke pale a hoʻopaʻa i ka vibration. Ke kiʻekiʻe loa nā koi kikoʻī, hiki ke koho ʻia nā bearings sliding hydrostatic wale nō.No ka pololei a me ke kiʻekiʻe-pololei mīkini wili, nā ʻano mea hana pololei, a me nā mea ʻē aʻe, hoʻohana nui ʻia nā bearings sliding.

3. Nā manawa hoʻouka kaumaha

ʻO nā bearings rolling, inā paha he mau pōpō pōleʻa a i ʻole nā ​​bearings roller, hiki ke wela a me ka luhi i nā noi kaumaha.No laila, i ka nui o ka ukana, hoʻohana pinepine ʻia nā bearings sliding, e like me nā wili wili, nā turbines mahu, nā mea aero-engine a me nā mīkini mining.

4. Nā manawa ʻē aʻe

No ka laʻana, ʻoi aku ka kiʻekiʻe o ka wikiwiki o ka hana, ʻoi aku ka nui o ka haʻalulu a me ka haʻalulu, a koi ʻia ka hana ʻana i ka wai a i ʻole ka corrosive medium, a hiki ke koho pono ʻia ka bearing sliding.

No ke ʻano o nā mīkini a me nā mea hana, ʻo ka hoʻohana ʻana i nā bearings rolling a me nā sliding bearings he mau pono a me nā hemahema, a pono e koho pono ʻia e like me ka ʻenehana maoli.I ka wā ma mua, hoʻohana maʻamau nā mea hoʻoheheʻe nui a me waena i nā bearings sliding i hoʻolei ʻia me nā alloys babbitt, no ka mea hiki iā lākou ke kūpaʻa i nā haʻahaʻa hopena nui, a ʻano kūʻokoʻa a paʻa.Hoʻohana nā mea hoʻoheheʻe auwae liʻiliʻi i nā bearings rolling, he kiʻekiʻe ka maikaʻi o ka hoʻouna ʻana, ʻoi aku ka maʻalahi, a maʻalahi hoʻi e mālama.Me ka hoʻomaikaʻi ʻana i ka ʻenehana hana ʻenehana, ʻo ka hapa nui o nā mea hoʻoheheʻe iwi nui e hoʻohana i nā bearings rolling.
