ʻO kanā pono a me nā hemahema o ka bearing nui o ka mana makani

 

TʻO nā ʻano nui o nā bearings spindle i hoʻohana ʻia no nā turbine makani megawatt he 3-point bearing bearing design a me 2-point bearing bearing design.E ʻoluʻolu e nānā i ka mea ma lalo neianā pōmaikaʻi a me nā pōʻino o kaʻO ka hāpai ʻana o eseʻano hana

 

Nā mea hoʻopaʻa wili poepoe + nā mea hoʻopaʻa wili poepoe

ʻO nā pono, ʻaʻohe a emi iki paha ke kaumaha e hana ana ma ka pahu pahu, ʻoiai ke hilinaʻi nei i ka lima torsion e kū i ka deformation liʻiliʻi, a he maʻalahi ka ʻākoakoa.

 

Eia nā hemahema:

1) He nui ka ʻae axial, a ʻaʻole maikaʻi ke kūlana o ke kikowaena ma ke kuhikuhi axial;

2) ʻAʻohe preload ma ke kaulahao nui, a he nui loa ka neʻe ʻana o ke axial ma hope o ka hoʻouka ʻana, a i ka manawa like, ma muli o ka nele o ka preload, ʻaʻole paha e wili kahi ʻōwili hoʻokahi, kahi e alakaʻi ai i ka paheʻe ʻana, kahi e hana ai i kahi ukana kiʻekiʻe loa a hoʻopilikia i ke ola o ka bearing;

3) He liʻiliʻi ka nui o ke koʻokoʻo, a he nui ka mana o ke kaumaha ma luna o ke koʻokoʻo.

 

Nā mea wili poepoe + nā mea hoʻopaʻa wili cylindrical

ʻO nā pōmaikaʻi o kēia kūkulu ʻana i ka bearing, ʻaʻohe a emi mai paha ke kaumaha e hana ana ma ka pahu pahu, ʻoiai ke hilinaʻi nei i ka lima torsion e kū i ka deformation liʻiliʻi, a he maʻalahi ka ʻākoakoa.

 

ʻO kaʻo nā hemahema penei:

1) He nui ka ʻae axial, a ʻaʻole maikaʻi ke kūlana o ke kikowaena ma ke kuhikuhi axial;

2) ʻAʻohe preload ma ke kaulahao nui, a he nui loa ka neʻe ʻana o ke axial ma hope o ka hoʻouka ʻana, a i ka manawa like, ma muli o ka nele o ka preload, ʻaʻole paha e wili kahi ʻōwili hoʻokahi, kahi e alakaʻi ai i ka paheʻe ʻana, kahi e hana ai i kahi ukana kiʻekiʻe loa a hoʻopilikia i ke ola o ka bearing;

3) ʻO ka nui o ke kiʻikuhi nui he nui a i haku ʻia paha me nā ʻāpana he nui, e hopena ana i ke kumukūʻai o ke kiʻikuhi nui he kiʻekiʻe a ʻoi aku ka paʻakikī o ka hana ʻana;

4) No ka mea, he ʻike nā bearings wili cylindrical i ka coaxiality a me ka deflection pili o nā apo o loko a me waho, he maikaʻi ʻole lākou i ka hoʻolālā a i ʻole ka ʻākoakoa ʻana.

I kēia hihia, ʻo ka ʻae radial o nā bearings roller spherical e alakaʻi i ka hōʻino ʻana i nā rollers cylindrical;

5) Ma muli o ka liʻiliʻi o ka nui o ke koʻokoʻo a me ka hali, ʻoi aku ka haʻahaʻa o ka paʻakikī o ka ʻōnaehana koʻokoʻo, a ʻoi aku ka hopena o ka ukana ma ke koʻokoʻo.

 

Nā bearings wili tapered lālani pālua + nā bearings wili cylindrical

ʻO nā pōmaikaʻi nui o kēia ʻano bearing:

1) ʻAʻohe ʻae axial, a ʻoi aku ka maikaʻi o ke kūlana axial;

2) Hiki ke hoʻonui ʻia ka mana halihali ma ka hoʻonui ʻana i ka mamao ma waena o nā bearings, a ʻoi aku ka nui o ka laulā kūpono o nā bearings;

3) ʻOi aku ka liʻiliʻi o ke anawaena o ke koʻokoʻo a me ka bearing, a ʻoi aku ka haʻahaʻa o ke kumukūʻai;

4) Ma muli o ka hoʻopau ʻia ʻana o ka axial clearance, ʻoi aku ke kiʻekiʻe o ka paʻakikī o ka ʻōnaehana shaft, a ʻaʻole nui ka mana o ka ukana hoʻoikaika ma luna.
