He aha ka Bearing Haʻahaʻa-Mahana

ʻAʻole pili ka bearing haʻahaʻa i kahi bearing e hana paʻa ana i nā wahi wela kiʻekiʻe (e kū'ē inā bearings wela kiʻekiʻe), akā, he bearing i hoʻolālā ʻia me nā mea kūikawā a me nā hoʻolālā kūkulu e hōʻemi i ke koina friction, a laila e hōʻemi ana i ka wela friction. ʻAe kēia i ka bearing e mālama i kahi mahana haʻahaʻa ʻoiai i ka wā hana lōʻihi.

 

Nā Bearingsme ka mahana hana ma lalo o -60 ℃ ua manaʻo ʻia he mau bearings haʻahaʻa. Hoʻohana nui ʻia lākou i nā pamu wai like ʻole, e like me nā pamu kinoea kūlohelohe liquefied, nā pamu naikokene wai (hydrogen, oxygen), nā pamu butane, nā pamu wai no nā rockets a me nā missiles, nā mokulele mokulele, a pēlā aku.

 

Ka Mahana Hana o nā Bearings Haʻahaʻa

Hōʻike ka mahana hana o kahi bearing haʻahaʻa i ka ʻenehana mea a me ka pae hana o ka bearing. Ana nui ʻia e ka ʻokoʻa o ka mahana ma waena o ke apo waho o ka bearing a me ka ʻaila hoʻoluʻu i hoʻokomo ʻia i ka wā o ka hana. ʻO ka mahana hana haʻahaʻa ke ʻano o ka lōʻihi o ke ola o ka bearing a me ka hana kiʻekiʻe.

 

Nā Māhele o nā Bearings Haʻahaʻa-Mahana

ʻO nā bearings haʻahaʻa haʻahaʻa he mau bearings ball groove hohonu hoʻokahi lālani a me nā bearings roller cylindrical.

 

Nonā mea e hāpai anake ʻike nei i ka hopu ʻana i nā mahana haʻahaʻa, ʻo ke kumu o waho ka loli o ka mahana, ʻoiai ʻo ke kumu o loko nā coefficients hoʻonui wela like ʻole o ke koʻokoʻo, ka mōlina, a me nā mea. Ke nui ka pae mahana, emi nā mea like ʻole ma nā helu like ʻole, e hōʻemi ana i ka ʻae a me ke kumu o ka jamming. No laila, no nā lako me kahi ākea hana ākea, me nā lako i hoʻohana ʻia i nā mahana haʻahaʻa, pono e helu i nā coefficients hoʻonui o nā mea a, inā hiki, e hoʻohana i nā mea me nā coefficients hoʻonui like no nā hopena maikaʻi aʻe.

 

Eia kekahi, i ka hoʻolālā kūkulu ʻana, he mea kūpono ke pale aku i ka hoʻohana ʻana i kahi bearing roller conical ma kēlā me kēia wēlau o ke koʻokoʻo. I loko o ia ʻano kūkulu, ʻo ka lōʻihi o ka mamao ma waena o nā bearings ʻelua, ʻoi aku ka kiʻekiʻe o ka manawa e jamming ai. Inā hoʻokomo ʻia kahi pālua o nā bearings tapered ma kekahi wēlau o ke koʻokoʻo, hiki iā lākou ke lawelawe ma ke ʻano he hoʻonohonoho koʻokoʻo, e kāohi ana i ka neʻe ʻana o ke axial. ʻO kekahi wēlau o ke koʻokoʻo, i hoʻohana ʻia me kahi bearing wili, e kāohi wale i nā ikaika radial, e ʻae ana i ka neʻe ʻana o ke axial i kaupalena ʻia me nā loli o ka mahana axial.

 

Koho Mea no nā Bearings Haʻahaʻa-Mahana

Koho ʻana o ke kila bearing no nā bearings haʻahaʻa

Hana pinepine ʻia nā bearings haʻahaʻa-wela me nā kila kila kila 9Cr18 a i ʻole 9Cr18Mo, a hiki ke hana ʻia mai ka beryllium bronze, nā keramika, a me nā mea ʻē aʻe. Ma lalo o nā mahana hana haʻahaʻa loa (mahana kiʻekiʻe loa -253℃), inā koi ka palena hana -253℃, hiki ke koho ʻia ka mea 6Cr14Mo akā pono e hoʻohana ʻia i loko o kahi ʻano vacuum.

 

I ka wā e hoʻohana ai i nā bearings haʻahaʻa haʻahaʻa, pono e uku ʻia ka nānā ʻana i nā pilikia e like me ka wela nui i hoʻokumu ʻia e ka lubrication maikaʻi ʻole, no laila he mea nui e koho i nā lubricants kūpono.
