ʻOi aku ka nui a i ʻole ka liʻiliʻi o ka ʻae hana ʻana ma mua o ka ʻae hoʻokomo ʻana ma muli o ka hopena hui o kēia mau kumu ʻelua.

ʻAʻole hiki ke hoʻoponopono ʻia kekahi mau huila wili no ka hoʻomaʻemaʻe ʻana, e waiho wale i ka wehe ʻana.ʻO kēia mau bearings he ʻeono mau ʻano, ʻo ia ke ʻano 0000 a hiki i ke ʻano 5000;Hiki ke hoʻololi i kekahi mau bearings rolling, akā ʻaʻole hiki ke wehe.ʻO 1000 type, 2000 type a me 3000 type rolling bearings, ʻoi aku ka liʻiliʻi o ka hoʻokomo ʻana o kēia mau ʻano o ka ʻōwili ʻana ma mua o ka ʻae mua ma hope o ka hoʻoponopono ʻana;Eia kekahi, hiki ke hoʻokaʻawale ʻia kekahi mau bearings, a hiki ke hoʻoponopono ʻia ka ʻae, aia nā ʻano 7000 (tapered roller bearings) ), 8000 type (thrust ball bearing) a me 9000 type (thrust roller bearing), ʻaʻole kēia mau ʻano ʻekolu o nā bearings. loaʻa ka ʻae mua;6000 type a me 7000 type rolling bearings, ua hoemiia ka radial clearance, axial clearance It also become smaller, and vice versa, oiai no ka Type 8000 a me Type 9000 rolling bearings, wale no ka axial clearance he mea pono.

He mea kōkua ka ʻae hoʻonohonoho kūpono no ka hana maʻamau o nā bearings rolling.Inā he liʻiliʻi loa ka hoʻomaʻemaʻe, e piʻi aʻe ka mahana o ka ʻōwili ʻana, a ʻaʻole e hana pono, a paʻa nā mea ʻōwili;inā ʻoi aku ka nui o ka hoʻomaʻemaʻe, e haʻalulu nui nā mea hana, a e walaʻau ka ʻōwili ʻana.

ʻO ke ʻano o ka nānā ʻana o ka hoʻomaʻemaʻe radial penei:

1. Ke ʻano manaʻo

1. Aia ka lima e hoʻohuli i ka bearing, a ʻo ka bearing e paʻa a maʻalahi me ka hoʻopaʻa ʻole.

2. E lulu i ke apo o waho o ka bearing ma ka lima, ʻoiai inā he 0.01mm wale nō ka hoʻomaʻemaʻe radial, ʻo ka neʻe ʻana o ke axial o ka piko kiʻekiʻe o ka bearing he 0.10 ~ 0.15mm.Hoʻolaʻa ʻia kēia ʻano hana i ka lālani radial ball bearings.

2. Ke ana ana

1. E hoʻopaʻa me ka mea hoʻoheheʻe manaʻo e hōʻoia i ke kūlana haʻahaʻa kiʻekiʻe loa o ka ʻōwili ʻana, e hoʻokomo i kahi anana feeler ma waena o ka mea ʻōwili a me ke apo o waho (i loko) ma 180 °, a ʻo ka mānoanoa o ke ana feeler me ka elasticity kūpono ka radial ka hoʻomaʻemaʻe ʻana o ka bearing.Hoʻohana nui ʻia kēia ʻano i nā bearings spherical a me nā bearings roller cylindrical.

2. E nānā me ke ana kelepona, e hoʻonoho mua i ke ana kelepona i ka ʻole, a laila e hoʻopaʻa i ke apo o waho o ka bearing wili.ʻO ka heluhelu ʻana o ka dial gauge ʻo ia ka hoʻomaʻemaʻe radial o ka bearing.

ʻO ke ʻano o ka nānā ʻana o ka axial clearance penei:

1. Ke ʻano manaʻo

E hoʻohana i kou mau manamana lima e nānā i ke axial clearance o nā bearings rolling.Pono e hoʻohana ʻia kēia ʻano i ka wā e ʻike ʻia ai ka hopena o ke kumu.Ke pani ʻia ka hopena o ka lāʻau a ʻaʻole hiki ke nānā ʻia me nā manamana lima no nā kumu ʻē aʻe, hiki ke nānā ʻia inā e holo manuahi ka lāʻau.

2. Ke ana ana

(1) E hōʻoia me kahi mea hoʻonā feeler, ua like ke ʻano o ka hana me ka nānā ʻana i ka ʻae ʻana o ka radial me kahi anana feeler, akā pono ka ʻae axial.

c=λ/(2sinβ)

kahi c——axial clearance, mm;

λ—— ka mānoanoa o ka ʻike ʻana, mm;

β——E lawe ana i ka huina kiko, (°).

(2) E hōʻoia me kahi anana kelepona.Ke hoʻoneʻe ʻia ka lāʻau me kahi crowbar e hana i ke kumu ma nā kūlana koʻikoʻi ʻelua, ʻo ka ʻokoʻa ma waena o nā heluhelu dial gauge ʻo ia ka axial clearance o ka bearing.Eia naʻe, ʻaʻole nui ka ikaika i hoʻopili ʻia i ka crowbar, inā ʻaʻole e hoʻoheheʻe ʻia ka casing, a inā he liʻiliʻi ka deformation, e hoʻopilikia ia i ka pololei o ke ana axial clearance.
