ʻO nā bearings turntable

ʻO ka papa hana rotary maʻamau i hoʻohana ʻia i nā mea mīkini mīkini CNC me ka papa hana kuhikuhi a me ka papa hana rotary CNC.

Hiki ke hoʻohana ʻia ka pākaukau rotary CNC no ka hoʻokō ʻana i kahi neʻe hānai pōʻai. Ma waho aʻe o ka hoʻomaopopo ʻana i ka neʻe ʻana o ka meaʻai pōʻai, hiki i ka CNC rotary table (i kapa ʻia ʻo CNC turntable) hiki ke hoʻopau i ka neʻe kuhikuhi.

Hoʻohana nui ʻia ka papa ʻaina rotary i nā mīkini milling CNC, nā mīkini ʻoluʻolu, nā lathe vertical like ʻole, ka wili hope a me nā mea mīkini ʻē aʻe. Ma waho aʻe o ke koi e hiki i ka papaʻaina rotary ke halihali maikaʻi i ke kaumaha o ka mea hana, pono nō hoʻi e hōʻoia i ka pololei o ka hoʻololi ʻana ma lalo o ka ukana.

ʻO ka turntable bearing, ʻo ia ka mea nui o ka turntable, ʻaʻole pono wale ka loaʻa ʻana o ka haʻahaʻa haʻahaʻa kiʻekiʻe, akā he kiʻekiʻe ka rotation pololei, kiʻekiʻe anti-overturning hiki, a me ka wikiwiki kiʻekiʻe i ka wā o ka hana o ka turntable.

Ma ka hoʻolālā onā papa ʻaina, ua mahele ʻia nā ʻano bearing i hoʻohana nui ʻia i kēia mau ʻano:

ʻO nā bearings pōpō pahu:huila huila cylindrical

Hiki i nā bearings pōleʻa ke kū i kahi ikaika axial, no laila, hoʻohana nui ʻia ka bearing e lawe i ke kaumaha o ka mea hana;ʻO nā huila huila cylindrical, ma ka ʻaoʻao ʻē aʻe, hoʻohana nui ʻia no ka hoʻonohonoho radial a me ka pale ʻana i nā mana radial o waho (e like me ka ʻoki ʻana, nā kaha milling, etc.). Hoʻohana nui ʻia kēia ʻano hoʻolālā a me ke kumu kūʻai ʻole. No ka mea, ʻo ka pōleʻa hoʻokuʻi ʻana he kiko-contact bearing, ʻo kona hiki ʻana i ke axial hiki ke kaupalena ʻia, a hoʻohana nui ʻia i nā papa ʻaina mīkini liʻiliʻi liʻiliʻi a liʻiliʻi paha. Eia kekahi, ʻoi aku ka paʻakikī o ka lubrication o nā pōpō thrust.

ʻO nā bearings hydrostatic:ʻO nā bearings huila cylindrical pololei

ʻO ka halihali hydrostatic kahi ʻano sliding bearing e hilinaʻi ana i ka hāʻawi ʻana i waho o ka ʻaila kaomi a hoʻokumu i kahi kiʻi ʻaila hydrostatic load-bearing i loko o ka bearing e hoʻokō ai i ka lubrication wai. Ke hana mau nei ka halihali hydrostatic ma lalo o ka lubrication wai mai ka hoʻomaka ʻana a i ka pau ʻana, no laila ʻaʻohe ʻaʻahu, ola lōʻihi a me ka mana hoʻomaka haʻahaʻa; Eia kekahi, ʻo kēia ʻano o ka halihali ʻana i nā mea maikaʻi o ke kiʻekiʻe o ka rotation pololei, ʻoi aku ka nui o ka ʻaila kiʻiʻoniʻoni, a hiki ke kāohi i ka oscillation kiʻiʻoniʻoni. ʻO nā bearings cylindrical roller bearing maikaʻi ka hiki ke lawe i ka radial, a ma muli o ka hoʻohana ʻana i nā bearings precision, hiki ke hōʻoia maikaʻi ʻia ka pololei o ka rotary table. Hiki i nā papa rotary e hoʻohana ana i kēia hoʻolālā ke kū i nā ikaika axial kiʻekiʻe loa, ʻoi aku ke kaumaha o kekahi ma mua o 200 tons a ʻoi aku ke anawaena turntable ma mua o 10 mika. Eia nō naʻe, aia kekahi mau hemahema o kēia ʻano hoʻolālā, no ka mea, pono e hoʻolako ʻia ka bearing hydrostatic me kahi ʻōnaehana hoʻolako ʻaila kūikawā e hoʻolako i ka ʻaila kaomi, ʻoi aku ka paʻakikī o ka mālama ʻana, a ʻoi aku ka kiʻekiʻe o ke kumukūʻai.

Nā huila huila i hala

He mea maʻamau nō hoʻi ka hoʻohana ʻana i nā bearings roller crossed ma nā turntables. Hōʻike ʻia nā bearings roller crossed e ʻelua raceways i ka bearing, ʻelua lālani o nā huila i hoʻonohonoho ʻia. Hoʻohālikelike ʻia me nā hui kuʻuna kuʻuna radial centering bearings hui pū ʻana,huila huila keahe paʻa, paʻa a maʻalahi hoʻi i ka hoʻolālā papaʻaina, a laila e hōʻemi ana i ke kumukūʻai o ka turntable.

Eia kekahi, ma muli o ka preload optimized, loaʻa i nā bearings kahi kiʻekiʻe o ka paʻakikī, e hōʻoiaʻiʻo ana i ka paʻakikī a me ka pololei o ka turntable. Mahalo i ka hoʻolālā ʻana o nā lālani ʻelua o nā rollers crossed, hiki ke hoʻonui nui ʻia ka lōʻihi o ka bearing, i hiki ai i kēia mau bearings ke kūpaʻa kiʻekiʻe i nā manawa hoʻohuli. I loko o nā bearings roller crossed, ʻelua ʻano: ʻo ka mua he cylindrical crossed roller bearings, a ʻo ka lua he tapered crossed roller bearings. Ma keʻano laulā, ʻoi aku ke kumu kūʻai o nā bearings roller crossed cylindrical ma mua o nā bearings rolled crossed roller a kūpono no nā noi turntable me nā māmā haʻahaʻa; Hoʻohana ʻia ka huila tapered crossed roller i ka hoʻolālā ʻōwili maʻemaʻe o ka ʻōwili tapered, no laila ua loaʻa kēia ʻano ʻano:

• Kiekie holo pololei

• Hiki ke holo wikiwiki

• Ua ho'ēmi 'ia ka lō'ihi o ka lā'au a me nā kumukū'ai mīkini, ka ho'ololi li'ili'i o ka geometry ma muli o ka ho'onui wela

• Māhele naylon, haʻahaʻa manawa o ka inertia, haʻahaʻa hoʻomaka torque, maʻalahi ke hoʻomalu i ka angular indexing

• Hoʻonui ʻia ka preload, ʻoʻoleʻa kiʻekiʻe a me ka holo haʻahaʻa

•Linear pili, kiʻekiʻe stiffness, kiʻekiʻe precision o alakaʻi wili hana

• Hāʻawi ke kila Carburized i ka hopena maikaʻi loa a me ka pale ʻana o ka ʻili

• He maʻalahi akā ua lubricated maikaʻi

I ke kau ʻana i nā bearings, pono wale ka mea kūʻai aku e hoʻouka i nā bearings i hala i nā kumu waiwai i ʻōlelo ʻia, ma mua o ka loaʻa ʻana o kahi kaʻina hoʻoponopono paʻakikī e like me nā bearings hydrostatic. He maʻalahi ka hoʻokomo ʻana i nā bearings roller crossed a maʻalahi hoʻi e hoʻoponopono i ke ʻano hoʻonohonoho kumu a i ʻole ke ʻano mālama. He kūpono nā bearings roller crossed no nā ʻano mīkini hoʻoheheʻe kūpaʻa a i ʻole paha, a me nā noi e like me nā wili kūpaʻa, ka huli ʻana a me nā mīkini wili nui.

Ma ke ʻano he kumu nui o ka spindle a me ka turntable o ka mīkini mīkini, ʻo ka bearing ka mea nui i ka hana o ka mīkini. I mea e hiki ai ke koho i ka nui kūpono a me ke ʻano o ka bearing, pono mākou e noʻonoʻo i nā kūlana hana like ʻole, e like me ka holo wikiwiki, lubrication, ke ʻano kau ʻana, spindle stiffness, pololei a me nā koi ʻē aʻe. E pili ana i ka bearing pono'ī, aia wale nō ma ka hoʻomaopopo piha ʻana i kāna mau hiʻohiʻona hoʻolālā a me nā hopena maikaʻi a me nā hemahema e hiki ai iā mākou ke lawe mai i ka hana maikaʻi loa o ka bearing.
Inā makemake ʻoe e ʻike hou aku i ka ʻike pili, e ʻoluʻolu e kelepona mai iā mākou:
