He aha ka hoʻomaʻemaʻe a pehea e ana ʻia ai ka hoʻomaʻemaʻe no nā bearings rolling?

ʻO ka hoʻomaʻemaʻe ʻana o kahi huila ʻōwili ʻo ia ka nui o ka hana e paʻa ai kekahi apo ma kahi a ʻo kekahi ma ke kuhikuhi radial a axial paha. ʻO ka hana kiʻekiʻe loa ma ka ʻaoʻao radial i kapa ʻia ʻo radial clearance, a ʻo ka hana kiʻekiʻe loa ma ke kuhikuhi axial i kapa ʻia ʻo axial clearance. ʻO ka ʻōlelo maʻamau, ʻoi aku ka nui o ka hoʻomaʻemaʻe radial, ʻoi aku ka nui o ka ʻae axial, a me ka hope. Wahi a ke kūlana o ka bearing, hiki ke hoʻokaʻawale ʻia ka ʻae ʻana i ʻekolu mau ʻano:

I. Hoʻokuʻu kumu

Hoʻokuʻu manuahi ma mua o ka hoʻokomo ʻana. Hoʻoholo ʻia ka hoʻomaʻemaʻe kumu e ka hana ʻana a me ka hui ʻana o ka mea hana.

2. E hoʻouka i ka ʻae

ʻIke ʻia hoʻi ʻo ka hoʻomaʻemaʻe kūpono, ʻo ia ka ʻae ʻana i ka wā i hoʻokomo ʻia ai ka bearing a me ka shaft a me ka hale bearing akā ʻaʻole i hana. ʻOi aku ka liʻiliʻi o ka ʻae ʻana ma mua o ka hoʻomaʻemaʻe kumu ma muli o ke kau ʻana o ke keʻakeʻa, a i ʻole e hoʻonui i ke apo o loko, e hoʻemi ana i ke apo o waho, a i ʻole nā ​​mea ʻelua.

3. Hoʻokuʻu hana

I ka wā e hana ana ka bearing, piʻi ka wela o ke apo i loko i ka palena kiʻekiʻe a me ka hoʻonui ʻana i ka wela i ka palena kiʻekiʻe, i emi iho ai ka ʻae ʻana. I ka manawa like, ma muli o ka hopena o ka ukana, hiki ke hoʻololi i ka elastic deformation ma ka wahi pili ma waena o ke kino holo a me ke ala heihei, e hoʻonui ai i ka ʻae ʻana. ʻOi aku ka nui a i ʻole ka liʻiliʻi o ka ʻae hana bearing ma mua o ka ʻae ʻana i kau ʻia ma muli o ka hopena hui o kēia mau kumu ʻelua.

ʻAʻole hiki ke hoʻoponopono ʻia a wehe ʻia paha kekahi mau huila ʻōwili. Loaʻa iā lākou i ʻeono mau hiʻohiʻona, mai 0000 a 5000; Aia nā ʻano 6000 (nā kihi pili kihi) a me ke ʻano 1000, Type 2000 a me Type 3000 me nā lua cone i ke apo o loko. ʻO ka hoʻokuʻu ʻana o kēia mau ʻano o nā bearings rolling, ma hope o ka hoʻoponopono ʻana, e ʻoi aku ka liʻiliʻi ma mua o ka ʻae mua. Eia kekahi, hiki ke hoʻoneʻe ʻia kekahi mau bearings, a hiki ke hoʻoponopono ʻia ka ʻae. ʻEkolu ʻano o ka bearings: Type 7000 (tapered roller bearing), type 8000 (thrust ball bearing) and type 9000 (thrust roller bearing). ʻAʻohe ʻae kumu i loko o kēia mau ʻano bearings ʻekolu. No ke ʻano 6000 a me ke ʻano 7000 rolling bearings, ua hoʻemi ʻia ka ʻae ʻana o ka radial a ua hoʻemi ʻia ka ʻae axial, a ʻo ia hoʻi, ʻoiai no ke ʻano 8000 a me ke ʻano 9000 rolling bearings, ʻo ka ʻae axial wale nō ka mea nui.

Hoʻomaʻamaʻa ka hoʻomaʻemaʻe kau kau ʻana i ka hana maʻamau o ka bearing rolling. He liʻiliʻi loa ka hoʻomaʻemaʻe, piʻi ka mahana o ka ʻōwili ʻana, ʻaʻole hiki ke hana maʻamau, no laila paʻa ke kino ʻōwili; ʻO ka hoʻomaʻemaʻe nui ʻana, ka haʻalulu ʻana o nā mea hana, ka walaʻau ʻōwili ʻana.

ʻO ke ʻano o ka nānā ʻana i ka radial clearance penei:

I. ʻAno ʻike

1. Me ka lawe lima ʻana, pono e maʻalahi a maʻalahi ka halihali me ka ʻole o ka pipili a me ka astringency.

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 ka axial o ka piko o ka bearing he 0.10-0.15mm. Hoʻohana ʻia kēia ʻano hana no ka lālani hoʻokahi centripetal ball bearings.

ʻAno ana

1. E nānā a hōʻoia i ke kūlana haʻahaʻa kiʻekiʻe o ka ʻōwili ʻana me kahi mea hoʻoheheʻe, e hoʻokomo i kahi feeler ma waena o ke kino ʻōwili 180 ° a me ke apo o waho (i loko), a ʻo ka mānoanoa kūpono o ka feeler ʻo ia ka radial clearance o ka bearing. Hoʻohana nui ʻia kēia ʻano i nā bearings self-aligning a me nā bearings roller cylindrical.

2, e nānā me ka hōʻailona dial, e hoʻonoho mua i ka hōʻailona kelepona i ka zero, a laila e hoʻokiʻekiʻe i ke apo o waho o ka ʻōwili ʻana, ʻo ka heluhelu ʻana i ke kelepona ʻo ka wehe radial o ka bearing.

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

1. ʻO ke ʻano sensory

E nānā i ka ʻae axial o ka ʻōwili ʻana me kou manamana lima. Pono e hoʻohana ʻia kēia ʻano i ka wā e ʻike ʻia ai ka hopena o ke kumu. Ke pani ʻia ka hope o ka lāʻau a ʻaʻole hiki ke nānā ʻia e nā manamana lima no nā kumu ʻē aʻe, e nānā inā hiki ke maʻalahi ka lāʻau i ka hoʻololi ʻana.

2. Ke ana ana

(1) E nānā me ka feeler. ʻO ke ʻano hana e like me ka nānā ʻana i ka hoʻomaʻemaʻe radial me ka feeler, akā pono ka ʻae axial.

C = lambda/sala (2 beta)

Kahi c -- axial clearance, mm;

-- Anana mānoanoa, mm;

-- Huina cone Angle, (°).

(2) E nānā me ka hōʻailona kelepona. Ke hoʻohana ʻia ka crowbar e hoʻokahe i ke kumu neʻe i ʻelua kūlana kiʻekiʻe, ʻo ka ʻokoʻa o ka heluhelu hōʻailona dial ʻo ka ʻae axial o ka bearing. Eia nō naʻe, ʻaʻole pono ka nui o ka ikaika i hoʻopili ʻia i ka crowbar, i ʻole e loaʻa i ka pūpū elastic deformation, ʻoiai inā he liʻiliʻi loa ka deformation, e hoʻopilikia ia i ka pololei o ke ana axial clearance.
