Nā bearings kaʻaahi - nā ʻano bearings gearbox axle a me nā noi

Me ka hoʻomohala ʻana o ke kaiāulu, ke hoʻomau nei ka hoʻomaikaʻi ʻana o ka ʻoihana hana mīkini kaʻaahi, e pili ana i ka ʻenehana hana bearing kaʻaahi e hoʻomaikaʻi mau nei, kahi o ke kuleana nui o ka bearing wili i loko o ka pahu pahu ʻo ia ka hiki ke hoʻoili paʻa i ka torque output i ka wā e holo ana ka locomotive i ka wikiwiki kiʻekiʻe, ʻo ia hoʻi, pono lākou e hāpai i ka ukana hopena hiki ke hoʻololi ʻia i loko o ke kaiapuni paʻakikī. ʻO nā ʻano bearing nui he mau bearing wili tapered, nā bearings pili ʻehā-kiko a me nā bearings wili cylindrical. ʻOkoʻa nā hoʻonohonoho bearing ma muli o ka hoʻolālā a me nā kūlana hana o ka pahu pahu.

 

Nā bearings pahu pahu axle

ʻO ka hana nui o nā bearings no nā pahu pahu:

Ka wikiwiki kiʻekiʻe; Ka hāpai ʻana i ke kaumaha kiʻekiʻe; Ke kūpaʻa haʻalulu a me ka haʻalulu; Ke kūpaʻa wela kiʻekiʻe.

Hoʻoholo ʻia ke koho ʻana o ka hali e like me ka nui o ka ʻāpana kūpono o ka pahu pahu, e noʻonoʻo ana i nā mea noi i luna, a ma ke ʻano laulā e koi ʻia kahi ola i helu ʻia ma mua o 2 miliona km.

 

Nā noi no ka bearing gearbox axle

1. Nā bearings wili i hoʻopili ʻia

Hiki ke hoʻokaʻawale ʻia nā bearings wili tapered, a hiki ke hoʻākoakoa ʻokoʻa ʻia ko lākou apo o loko a me ke apo o waho. ʻO ka pilina linear i hoʻoponopono ʻia ma waena o nā mea wili a me ke ala holo e pale aku i nā pilikia lihi. Hiki i nā bearings wili tapered ke kū i nā ukana radial a me axial kiʻekiʻe. No ka mea hiki i kēia mau bearings ke kū i nā ikaika axial ma kekahi ʻaoʻao wale nō, pono e hoʻohana ʻia i nā noi hoʻohui. Hoʻohana ʻia kēia ʻano bearing i nā pahu pahu a me nā pahu axle.

 

2. ʻO ka bearing pili ʻehā-kiko

ʻO nā bearings pōpō pili ʻehā-kiko he mau bearings pōpō pili angular. Hiki iā ia ke kū i nā ukana axial ma nā ʻaoʻao ʻelua a ua hui pū ʻia me nā bearings wili cylindrical e kū i nā ikaika radial, me kahi kūpono radial clearance. ʻO ke ʻano māhele o ke apo o loko e hiki ai iā ia ke hōʻuluʻulu i nā pōpō kila hou aʻe. Hoʻohana ʻia kēia mau bearings i nā pahu pahu.

 

3.Nā mea hoʻopaʻa wili cylindrical

ʻOi aku ka nui o ka hoʻohana ʻia ʻana o nā bearings cylindrical lālani hoʻokahi i nā bearings kaʻaahi ma mua o nā bearings ʻē aʻe no ka mea hiki ke hoʻokaʻawale ʻia ke apo o loko mai ka ʻākoakoa i haku ʻia me ke apo o waho, nā wili a me ka hale paʻahao, he mea pono loa ia no ke kau ʻana, ka wehe ʻana, ka mālama ʻana a me ka nānā ʻana i ka bearing. Hiki i nā bearings wili cylindrical ke kū i nā ikaika radial kiʻekiʻe, a ʻo ka hoʻopili linear i hoʻoponopono ʻia ma waena o nā mea wili a me ke ala holo e hoʻopau i nā pilikia lihi, e hoʻonui ana i ka hilinaʻi o nā noi bearing. ʻO ka hui pū ʻana o nā bearings wili cylindrical NJ a me NUP hiki ke kū i ka ikaika axial mau. Hoʻohana ʻia kēia mau bearings i nā motika traction, nā pahu pahu, a me nā hoʻokele koʻokoʻo hollow wheelset.

 

4. Nā bearings i hoʻokaʻawale ʻia

Ma lalo o kekahi mau kūlana hana maikaʻi ʻole a kūikawā paha, hiki ke hōʻino ʻia ka bearing shaft a me ka bearing motor ma muli o ka voltage hou aʻe. ʻOiai ua hemolele ke kaʻina hana o ka motor, ʻaʻole hiki ke pale loa i ka ʻokoʻa hiki ma waena o ka rotor a me ka stator ma muli o ka asymmetry electromagnetic, no laila ke hele nei ke au ma o ka bearing a hana i kahi kaapuni pani. I mea e pale aku ai i ke kūlana i luna, e hoʻopili i kahi uhi keramika oxide ma luna o ka ʻili o ke apo waho o ka bearing e ālai i ka voltage ʻaʻole emi ma lalo o 1000V, a pale i ka bearing mai ka hāʻule ʻana o ka bearing ma muli o ka ʻino uila i hoʻokumu ʻia e ka voltage hou aʻe.
