He aha ke kaʻina hana superfinishing bearing?

ʻAʻole hoʻohana wale ʻia ke kaʻina hana superfinishing i ka ʻoihana bearing, akā, i nā mīkini hoʻi, a ua hoʻomaka pū nā mīkini a me nā mea hana kikoʻī ʻē aʻe e hoʻohana i kēia kaʻina hana.

He aha ka bearing superprecision?

ʻO ka bearing superfinishing kahi ʻano smoothing he neʻe hānai e hoʻokō ai i ka micro-grinding.

ʻO ka ʻili ma mua o ka superfinishing ua hoʻohuli pololei ʻia a wili ʻia. ʻO ke kikoʻī, pili ia i kahi ʻano hana hoʻomaʻemaʻe e hoʻokau ana i kahi kaomi liʻiliʻi ma luna o ka workpiece me kahi mea hana abrasive grained maikaʻi (pōhaku ʻaila) ma lalo o nā kūlana lubrication a me ke anuanu maikaʻi, a hana i kahi neʻe oscillation reciprocating wikiwiki a pōkole ma luna o ka workpiece e wili ana i kahi wikiwiki i ke kuhikuhi wili workpiece maloʻo kū pololei.

He aha ke kuleana o ka bearing superfinishing?

I ke kaʻina hana hana o nā bearings rolling, ʻo ka superfinishing ka hana hope loa o ka hana ʻana i ke apo bearing, kahi mea nui e hōʻemi a hoʻopau paha i ka ʻokoʻa pōʻai i waiho ʻia e ka hana wili ʻana, hoʻoponopono i ka hewa ʻano o ka ʻauwaha, hoʻomaʻemaʻe i kona ʻili, hoʻomaikaʻi i nā waiwai kino a me nā mechanical o ka ʻili, hoʻemi i ka haʻalulu a me ka walaʻau o ka bearing, a hoʻomaikaʻi i ka hana o ka bearing.

Hiki ke hoʻokomo ʻia i loko o nā ʻano ʻekolu aʻe

1. Hiki iā ia ke hōʻemi pono i ka waviness. I ke kaʻina hana o ka super-finishing, i mea e hōʻoia ai e hana mau ana ka pōhaku aila ma ka piko o ka nalu a ʻaʻole e pili me ke awāwa, ʻo ke arc o ka pōhaku aila e pili ana me ka workpiece ≥ ka nalu o ka waviness ma ka ʻili o ka workpiece, i ʻoi aku ka nui o ke kaomi pili o ka piko, a ua wehe ʻia ka piko convex, a laila e hōʻemi ana i ka waviness.

2. Hoʻomaikaʻi i ka hewa groove o ke ala holo pōpō. Hiki i ka Super-finishing ke hoʻomaikaʻi maikaʻi i ka hewa groove o kahi 30% o nā ala holo.

3. Hiki iā ia ke hana i ke kaumaha compressive ma luna o ka ʻili o ka wili maikaʻi loa. I ke kaʻina hana o ka superfinishing, hana nui ʻia ka deformation plastic anu, no laila ma hope o ka superfinishing, hoʻokumu ʻia ke kaumaha compressive koena ma luna o ka ʻili o ka workpiece.

4. Hiki iā ia ke hoʻonui i ka wahi pili o ka ʻili hana o ka ferrule. Ma hope o ka hoʻopau ʻana, hiki ke hoʻonui ʻia ka wahi pili o ka ʻili hana o ka ferrule mai 15% ~ 40% ma hope o ka wili ʻana i 80% ~ 95%.

Ke kaʻina hana superfinishing bearings:

1. ʻOki ʻana i nā bearings

Ke pili ka ʻili o ka pōhaku wili me ka piko convex o ka ʻili raceway ʻino, ma muli o ka wahi pili liʻiliʻi a me ka ikaika nui ma ka ʻāpana ʻāpana, ma lalo o ka hana o kekahi kaomi, ua hoʻokomo mua ʻia ka pōhaku wili i ka hana "ʻoki hope" o ka workpiece bearing, i hāʻule ai kekahi hapa o nā ʻāpana abrasive ma luna o ka ʻili o ka pōhaku wili a ʻokiʻoki, e hōʻike ana i kekahi mau hua abrasive ʻoi hou a me nā ʻaoʻao ʻoki. I ka manawa like, ʻoki koke ʻia ka puʻupuʻu o ka ʻili o ka workpiece bearing, a wehe ʻia ka crest a me ka papa wili ma luna o ka workpiece bearing ma ka ʻoki ʻana a me ka ʻoki hope. Ua kapa ʻia kēia pae ʻo ka pae ʻoki, a ma kēia pae kahi e wehe ʻia ai ka hapa nui o ka ʻae metala.

2. Ka ʻoki hapa ʻana o nā bearings

I ka hoʻomau ʻana o ka mīkini ʻana, ua hoʻomaʻemaʻe mālie ʻia ka ʻili o ka mea hana e hali ana. I kēia manawa, piʻi ka wahi pili ma waena o ka pōhaku wili a me ka ʻili o ka mea hana, emi ke kaomi ma kēlā me kēia ʻāpana, emi ka hohonu o ka ʻoki ʻana, a emi ka hiki ke ʻoki. I ka manawa like, ua ālai ʻia nā pores ma luna o ka ʻili o ka pōhaku wili, a aia ka pōhaku wili i ke kūlana ʻoki hapa. Ua ʻike ʻia kēia pae ʻo ke kahua ʻoki hapa o ka hoʻopau ʻana i ka bearing, kahi e māmā ai nā māka ʻoki ma luna o ka ʻili o ka mea hana e hali ana a ʻeleʻele ka ʻōlinolino.

3. Kahua hoʻopau

Hiki ke hoʻokaʻawale ʻia kēia kahua i ʻelua mau ʻanuʻu: ʻo kekahi ke kahua hoʻololi wili; ʻO ka lua ke kahua wili ma hope o ka hoʻōki ʻana i ka ʻoki ʻana

Ka pae hoʻololi wili:

Hoʻowali ʻia ka palaoa abrasive iā ia iho, hoʻomaʻemaʻe ʻia ka lihi o ka palaoa abrasive, hoʻomaka ka hoʻokomo ʻia ʻana o ka ʻokikene chip i loko o ka hakahaka o ka pōhaku ʻaila, ālai ka pauka abrasive i nā pores o ka pōhaku ʻaila, i hiki ai ke ʻoki wale ʻia ka palaoa abrasive me ka nāwaliwali, me ka extrusion a me ka wili ʻana, a laila hoʻemi koke ʻia ka ʻili o ka workpiece, a hoʻopili ʻia ka ʻili o ka pōhaku ʻaila me ka ʻokikene chip ʻeleʻele.

E ho'ōki i ka hana wili ʻoki:

Ua laumania loa ka paio ʻana o ka pōhaku ʻaila a me ka ʻāpana hana, ua hoʻonui nui ʻia ka wahi pili, ua emi ke kaomi, ua hiki i ka palaoa abrasive ke komo i loko o ka ʻili ʻaila a hoʻopili me ka workpiece, ke kaulike ʻia ke kaomi ʻili ʻaila o ka ʻili e hali ana me ke kaomi ʻili ʻaila, ua lana ka pōhaku ʻaila. I ka wā o ka hoʻokumu ʻana o kahi ʻili ʻaila, ʻaʻohe hopena ʻoki. He mea kūikawā kēia pae i ka superfinishing.
