No ke aha i koho ai ka hapa nui o nā mīkini mining i nā bearings rolling ma kahi o nā bearings sliding?

Ma ke ʻano he ʻāpana koʻikoʻi a koʻikoʻi hoʻi i nā huahana mechanical, he kuleana koʻikoʻi nā bearings i ke kākoʻo ʻana i nā ʻau wili. Wahi a nā ʻano friction like ʻole i loko o ka bearing, ua māhele ʻia ka bearing i ka bearing friction rolling (i kapa ʻia ʻo ka bearing rolling) a me ka bearing friction sliding (i kapa ʻia ʻo ka bearing sliding). Loaʻa i nā ʻano ʻelua o nā bearings ko lākou mau ʻano ponoʻī i ke ʻano, a he mau pono a me nā hemahema ko kēlā me kēia i ka hana.

Hoʻohālikelike ʻana o nā bearings wili a me nā bearings maʻemaʻe

1. Hoʻohālikelike o ke ʻano a me ke ʻano neʻe

ʻO ka ʻokoʻa maopopo loa ma waena o nā bearings rolling a menā mea hoʻopili maʻemaʻeʻo ia ke alo a i ʻole ka nele o nā mea ʻōwili.

Loaʻa i nā bearings ʻōwili nā mea ʻōwili (pōpō, nā ʻōwili cylindrical, nā ʻōwili tapered, nā ʻōwili nila) e hilinaʻi nei i kā lākou wili ʻana e kākoʻo i ke koʻokoʻo wili, no laila he kiko ka ʻāpana pili, a ʻo ka nui o nā mea ʻōwili, ʻoi aku ka nui o nā kiko pili.

Nā bearings maʻemaʻeʻaʻohe ona mau mea ʻōwili a hilinaʻi i nā ʻili laumania e kākoʻo i ke koʻokoʻo wili, no laila he ʻili ka ʻāpana pili.

 

ʻO ka ʻokoʻa o ke ʻano o nā mea ʻelua e hoʻoholo ai ke ʻōwili nei ke ʻano neʻe o ka bearing wili, a ke paheʻe nei ke ʻano neʻe o ka bearing paheʻe, no laila ʻokoʻa loa ke kūlana friction.

 

2. Hoʻohālikelike o ka hiki ke hāpai

Ma keʻano laulā, ma muli o ka nui o ka ʻāpana halihali o ka bearing paheʻe, ʻoi aku ka nui o kona hiki ke halihali ma mua o ka bearing wili, a ʻaʻole kiʻekiʻe ka hiki o ka bearing wili ke hali i ka ukana hopena, akā hiki i ka bearing lubricated wai piha ke hali i kahi ukana hopena nui ma muli o ke kuleana o ka cushioning a me ka omo haʻalulu ma muli o ka ʻili ʻaila lubricating. Ke kiʻekiʻe ka wikiwiki o ka wili ʻana, piʻi ka ikaika centrifugal o nā mea wili i loko o ka bearing wili, a ua emi kona hiki ke halihali ukana (hiki ke walaʻau i nā wikiwiki kiʻekiʻe). I ke ʻano o nā bearings plain dynamic, piʻi ko lākou hiki ke halihali ukana me nā wikiwiki kiʻekiʻe.

 

3. Hoʻohālikelike o ke koina friction a me ke kū'ē kū'ē hoʻomaka

Ma lalo o nā kūlana hana maʻamau, ʻoi aku ka haʻahaʻa o ke koina friction o nā bearings ʻōwili ma mua o nā bearings maʻamau, a ʻoi aku ka paʻa o ke kumukūʻai. Hoʻopilikia maʻalahi ʻia ka lubrication o nā bearings paheʻe e nā mea o waho e like me ka wikiwiki a me ka haʻalulu, a ʻokoʻa loa ke koina friction.

 

I ka hoʻomaka ʻana, ʻoi aku ka nui o ke kū'ē ma mua o ke kū'ē ʻōwili no ka mea ʻaʻole i hoʻokumu ka kū'ē paheʻe i kahi ʻili aila paʻa, akā he liʻiliʻi loa ke kū'ē friction hoʻomaka a me ke koina friction hana o ka kū'ē paheʻe hydrostatic.

 

4. Hoʻohālikelike o nā wikiwiki hana kūpono

Ma muli o ka palena o ka ikaika centrifugal o ka ʻāpana ʻōwili a me ka piʻi ʻana o ka mahana o ka bearing, ʻaʻole hiki ke kiʻekiʻe loa ka wikiwiki o ka bearing ʻōwili, a kūpono ia no nā kūlana hana wikiwiki waena a me ka haʻahaʻa. ʻAʻole pono e kiʻekiʻe loa ka wikiwiki o ka hana no nā bearings lubricated wai piha ʻole ma muli o ka hoʻomehana a me ke komo ʻana o ka bearing. He maikaʻi loa ka hana wikiwiki o nā bearings lubricated wai piha, ʻoiai ke lubricated ʻia nā bearings hydrostatic plain me ka ea, a hiki i ko lākou wikiwiki rotational ke hiki i 100,000 r/min.

 

5. Hoʻohālikelike o ka pohō mana

Ma muli o ke koina friction liʻiliʻi o nā bearings ʻōwili, ʻaʻole nui ka pohō mana o lākou, ʻoi aku ka liʻiliʻi ma mua o nā bearings i hoʻopihapiha ʻole ʻia me ka wai, akā e hoʻonui nui ʻia ia ke hoʻopihapiha ʻia a hoʻokomo pono ʻia. He haʻahaʻa ka pohō mana frictional o nā bearings i hoʻopihapiha piha ʻia me ka wai, akā no nā bearings hydrostatic plain, ʻoi aku ka nui o ka pohō mana ma mua o nā bearings hydrostatic plain ma muli o ka pohō o ka mana pamu aila.

 

6. Hoʻohālikelike o ke ola lawelawe

Ma muli o ka hopena o ka lua ʻana o nā mea a me ka luhi, ua hoʻolālā pinepine ʻia nā bearings ʻōwili no 5 ~ 10 mau makahiki, a i ʻole e hoʻololi ʻia i ka wā o ka hoʻoponopono hou ʻana. Ua ʻino loa nā pads o nā bearings i hoʻopiha ʻole ʻia me ka wai a pono e hoʻololi pinepine ʻia. ʻO ke ola o nā bearings i hoʻopiha piha ʻia me ka wai, ʻaʻole i kaupalena ʻia, akā i ka hana maoli, hiki ke hāʻule ka luhi o ka mea bearing ma muli o ke kaʻapuni koʻikoʻi, ʻoiai no nā bearings plain dynamic.

 

7. Hoʻohālikelike o ka pololei o ka wili ʻana

ʻO ka maʻamau, he kiʻekiʻe ka pololei o ka wili ʻana o nā bearings wili ma muli o ka liʻiliʻi o ka radial clearance. ʻO ka bearing lubricated wai piha ʻole i ke kūlana o ka lubrication palena a i ʻole ka lubrication hui ʻia, a paʻa ʻole ka hana, a koʻikoʻi ke komo ʻana, a haʻahaʻa ka pololei. Ma muli o ke alo o ka ʻili ʻaila, ʻo ka bearing lubricated wai piha e hoʻomoe i ka haʻalulu me ka pololei kiʻekiʻe. ʻOi aku ka pololei o ka wili ʻana o nā bearings maʻemaʻe hydrostatic.

 

8. Hoʻohālikelike ʻana o nā ʻano ʻē aʻe

Hoʻohana nā bearings ʻōwili i ka ʻaila, ka momona a i ʻole ka lubricant paʻa, he liʻiliʻi loa ka nui, nui ka nui i ka wikiwiki kiʻekiʻe, pono e kiʻekiʻe ka maʻemaʻe o ka ʻaila, no laila pono e sila ʻia, akā maʻalahi ke hoʻololi i ka bearing, a ʻaʻole pono e hoʻoponopono i ka puke pai. No nā bearings maʻamau, me ka hoʻohui ʻana i nā bearings lubrication wai piha ʻole, ʻo ka lubricant maʻamau he wai a kinoea paha, nui loa ka nui, kiʻekiʻe loa nā koi hoʻomaʻemaʻe ʻaila, pono e hoʻololi pinepine i nā pads bearing, a i kekahi manawa hoʻoponopono ʻia ka puke pai.

 

Ke koho ʻana o nā bearings ʻōwili a me nā bearings maʻemaʻe

Ma muli o nā kūlana hana paʻakikī a ʻokoʻa hoʻi, ʻaʻohe kūlana hoʻokahi no ke koho ʻana i nā bearings ʻōwili a me nā bearings paheʻe. Ma muli o ke koina friction liʻiliʻi, ke kūʻē hoʻomaka liʻiliʻi, ka ʻike, ka pono kiʻekiʻe, a me ke kūlana maʻamau, loaʻa i nā bearings ʻōwili ka hiki ke hoʻololi a me ka versatility maikaʻi loa, a he kūpono hoʻi e hoʻohana, lubricate a mālama, a hāʻawi pinepine ʻia i ka mea nui i ke koho ʻana, no laila ua hoʻohana nui ʻia lākou i nā mīkini maʻamau. Loaʻa i nā bearings maʻamau kekahi mau pono kūikawā, kahi i hoʻohana pinepine ʻia i kekahi mau manawa kahi hiki ʻole ke hoʻohana ʻia nā bearings ʻōwili, kūpono ʻole a i ʻole me nā pono ʻole, e like me kēia mau manawa:

 

1. Ua kaupalena ʻia ka nui o ka wahi radial, a i ʻole pono e māhele ʻia ke kau ʻana

Ma muli o ke apo o loko, ke apo o waho, ka ʻāpana ʻōwili a me ka hale paʻahao i loko o ke ʻano, nui ka nui radial o ka bearing ʻōwili, a ua kaupalena ʻia ka hoʻohana ʻana i kekahi ʻano. Loaʻa nā bearing wili nila ke paʻakikī nā ana radial, a inā pono, pono nā bearing maʻamau. No nā ʻāpana i pilikia ke loaʻa nā bearing, a i ʻole ʻaʻole hiki ke kau ʻia mai ke kuhikuhi axial, a i ʻole kahi e pono ai ke māhele ʻia nā ʻāpana i nā ʻāpana, hoʻohana ʻia nā bearing maʻamau i māhele ʻia.

 

2. Nā hanana kikoʻī kiʻekiʻe

Ke loaʻa i ka bearing i hoʻohana ʻia nā koi kikoʻī kiʻekiʻe, koho pinepine ʻia ka bearing paheʻe, no ka mea, hiki i ka ʻili ʻaila lubricating o ka bearing paheʻe ke pale i ka omo ʻana o ka haʻalulu, a i ka wā e kiʻekiʻe loa ai ka pololei, hiki ke koho ʻia ka bearing paheʻe hydrostatic. No nā mīkini wili kikoʻī a me ke kikoʻī kiʻekiʻe, nā mea hana kikoʻī like ʻole, a me nā mea ʻē aʻe, hoʻohana nui ʻia nā bearing paheʻe.

 

3. Nā manawa kaumaha

ʻO nā bearings ʻōwili, inā he bearings pōpō a i ʻole nā ​​​​bearings wili, he maʻalahi i ka wela a me ka luhi i nā kūlana hana kaumaha. No laila, i ka wā e nui ai ka ukana, hoʻohana nui ʻia nā bearings paheʻe, e like me nā wili ʻōwili, nā turbine mahu, nā mea pono mīkini aero a me nā mīkini mining.

 

4. Nā manawa ʻē aʻe

No ka laʻana, kiʻekiʻe loa ka wikiwiki o ka hana, nui loa ka haʻalulu a me ka haʻalulu, a me ka pono e hana i ka wai a i ʻole nā ​​​​mea ʻino, a me nā mea ʻē aʻe, hiki ke koho pono ʻia nā bearings paheʻe.

 

No kekahi ʻano mīkini a me nā lako, ʻo ka hoʻohana ʻana o nā bearings ʻōwili a me nā bearings paheʻe, loaʻa i kēlā me kēia kona mau pono a me nā hemahema, a pono e koho pono ʻia me ka papahana maoli. I ka wā ma mua, ua hoʻohana pinepine nā mea wili nui a me ka waena i nā bearings paheʻe i hoʻolei ʻia me babbitt, no ka mea hiki iā lākou ke kū i nā ukana hopena nui, a ʻoi aku ka paʻa a me ke kūpaʻa. Hoʻohana nui ʻia ka mea wili ʻāwae liʻiliʻi me nā bearings ʻōwili, nona ka pono hoʻoili kiʻekiʻe, ʻoi aku ka naʻau a maʻalahi hoʻi e mālama. Me ka hoʻomaikaʻi ʻana o ka pae loea o ka hana ʻana i nā bearings ʻōwili, hoʻohana ʻia ka hapa nui o nā mea haki ʻāwae nui i nā bearings ʻōwili.
