Chokwadi Nezve High-Speed ​​Bearings: Kurumidza Mhinduro

Yekumhanya-mhanya haingori kutakura ine nhamba hombe yeRPM pane dhatabheti. Mune CNC spindle, inogoneka kumhanya inoenderana neiyo yakazara inotakura sisitimu: kubereka saizi, kukunguruka-chinhu, dhizaini yemukati, kona yekubata, preload, kuronga, kirasi yechokwadi, nzira yekuzora, inokwana, kutonhora, mutoro, kusvibisa kudzora, uye spindle yekupisa maitiro.

Ichi ndicho chikonzero mabheya maviri ane zviyero zvakafanana achigona kuve nekumhanya kwakasiyana kwazvo, kukwira kwetembiricha, kuoma, ruzha, uye hupenyu hwesevhisi. Ndosaka bheya rinoita zvakanaka pa24,000 RPM mune imwe spindle ringave risingakodzere kumhanya kwakafanana mune yakakura, yakawandisa yakatakura, yakasiyana lubricated spindle.

Kiyi yekutora: ongorora yakakwira-kumhanya mabhengi sechikamu chehurongwa. Maximum RPM inongopinza imwe chete. Speed ​​​​factory, preload, lubrication, kugadzikana kwemafuta, kuomarara, mutoro wekuremerwa, kutakura kurongeka, uye mhando yekuisa inotarisisa kana kutakura kunogona kushanda zvakavimbika mune chaiyo spindle.

Bvunza nezve CNC Spindle Bearing Selection

Chii chinonzi High-Speed ​​Bearings?

High-speed mabearings ane madhizaini akakwenenzverwa kuti ashande pamwero wakakwirira wekutenderera uku uchidzora kukwenya, kugadzirwa kwekupisa, centrifugal mhedzisiro, maitiro ekuzora, vibration, uye kumhanya chaiko. Mumuchina-chishandiso uye CNC spindle application, akajairika akanyanya-kumhanya mhinduro anosanganisira super-chaiyo angular kuonana bhora mabearings , anowanzo kupihwa seakafananidzwa seti ane yakatsanangurwa preload.

Zvichienderana nekugadzirwa kwespindle, high-speed angular contact ball bearings inogona kusanganiswa ne cylindrical roller bearings kana mamwe marudzi ekubereka kuti ape chiyero chinodiwa chekutsigira radial, axial tsigiro, kuoma, kukwanisa kwekuwedzera kwekushisa, uye kukurumidza.

Nei RPM Yega Isiri Yakashata Kuenzanisa Metric

Iyo 20 mm inotakura inomhanya pa30,000 RPM uye 80 mm inotakura inomhanya pa30,000 RPM hainzwe zvakafanana nekumhanya mamiriro. Iyo yakakura bearing ine yakakwirira rolling-element velocity uye centrifugal mhedzisiro. Nechikonzero ichi, mainjiniya anotakura anowanzo shandisa yekumhanyisa parameter zvichienderana nekutenderera kumhanya uye kubereka zvinoreva dhayamita.

Speed ​​factor = n × d _m

uko n = kutenderera kumhanya mu r/min

d _m = (d + D) ÷ 2 , apo d iri kubereka dhayamita yakabora uye D iri kunze kwedhayamita mumm.

Iyo n × d _m kukosha inobatsira pakuenzanisa kusimba kwekumhanya, asi haisati iri yepasirese yekupfuura / kutadza muganho. Iko kukosha kunotenderwa kunoenderana neinotakura nhevedzano, keji, bhora zvinhu, preload, lubrication, kubvisa kupisa, mutoro, inokwana, uye mugadziri dhizaini data.

6 Zvinhu Zvinonyatso sarudza Yepamusoro-Speed ​​Bearing Performance

1. Kutakura Kukura uye Yemukati Geometry

Zvidiki zvinotenderedza zvinhu uye yakagadziridzwa yemukati geometry inogona kuderedza centrifugal simba uye kukwesha nekumhanya kwakanyanya. Nekudaro, kudzikisira saizi yebhora kunogona zvakare kuchinja mutoro wekuremerwa uye kuoma. Yakakwira-kumhanya dhizaini saka inosanganisira tradeoff pakati pekumhanya, kusimba, mutoro wekuremerwa, kukwira kwetembiricha, uye hupenyu hunodiwa hwe spindle.

2. Bata kona

Angular yekubata bhora mabearings anotakura mutoro pamwe neakona yekubata pakati pemabhora uye mijaho. Makona madiki ekusangana anowanzo kubatanidzwa neakakwira-kumhanya spindle dhizaini, nepo mahombe ekusangana anogona kupa yakakura axial mutoro kugona. Iyo kona chaiyo inofanirwa kusarudzwa yakatenderedza iyo spindle yekucheka mutoro, axial kuomarara zvinodiwa, chishandiso chekushandisa, kurongeka kwekutakura, uye kumhanya kwechinangwa.

Usasarudza kuonana angle kubva kumhanya wega. Kubata ine yakanakisa theoretical yekumhanya kugona inogona kuve sarudzo isina kunaka kana iyo spindle ichida kwakawanda axial kuomarara kana thrust kugona kupfuura iyo gadziriro inogona kupa.

3. Preload

Preload inobvisa kutamba kwemukati uye inogona kuvandudza spindle kuomarara uye kumhanya chaiko. Asi zvakawanda preload haisi nani nguva dzose. Yakawandisa preload inowedzera yemukati yekusangana mutoro, kukwesha, uye kupisa, izvo zvinogona kuderedza zvinokwanisika kukurumidza uye kubereka hupenyu.

4. Lubrication Method uye Lubricant Quantity

High-speed spindle bearings inonyatsonzwa nekuzora. Mafuta mashoma akawandisa anogona kukonzera kusakwana kwemafirimu kuumbwa uye kupfeka. Giresi yakawandisa inogona kuwedzera churning, kupokana, uye tembiricha, kunyanya panguva yekumhanya-mukati.

5. Thermal Management

Sezvo tembiricha yekutakura inokwira, lubricant viscosity inodonha uye inotakura mhete, shaft, imba, uye masipidhi zvinhu zvinowedzera. Idzi shanduko dzinogona kushandura mashandiro ekutanga uye ekufambisa clearance. Chipindo chinotsiga kana kuchitonhora chinogona kuita zvakasiyana mushure menguva refu yekumhanya-mhanya.

Inoshanda spindle dhizaini saka inofunga kubereka kupisa chizvarwa pamwe chete nekutonhodza kwedzimba, shaft kukura, kupisa mota, inotonhorera kana yekutonhodza mvura maseketi, tembiricha yekuzora, uye maitiro ekudziya-up.

6. Precision Kirasi, Inokodzera, Kuiswa, uye Hutsanana

Super-chaiyo mabhengi anogona kushandisa makirasi ekushivirira akadai ISO P4, P2, kana mugadziri-chaiwo mamakisi echokwadi. Aya makirasi akakosha, asi haavimbise iyo yekupedzisira spindle runout ega. Shaft geometry, imba geometry, pendekete squareness, inokwana, clamping simba, inofananidzwa-seti kutaridzika, kuchena kwegungano, uye mudziyo wekubata-zvishandiso zvese zvinopesvedzera mhedzisiro yakaunganidzwa.

Pakumhanya kwakanyanya, zvikanganiso zvegungano diki uye kusvibiswa zvinogona kuve masosi makuru ekupisa, kuzunguzika, uye kupfeka nguva isati yakwana.

Hybrid Ceramic vs Simbi Bearings yeAkakwira-Speed ​​Spindles

Hybrid ceramic bearings anowanzo shandisa silicon nitride (Si ₃N ₄) inomonereka zvinhu zvine mhete dzine simbi. Izvo hazvisi zvizere zveceramic bearings. Mabhora avo akareruka eceramic anogona kudzikisa centrifugal mhedzisiro pakumhanya kwakakwira uye anogona kutsigira kukwesha kwakadzika uye kudzika kupisa chizvarwa mumasipidhi akagadzirwa nemazvo.

Nekudaro, mabhora eceramic haaite otomatiki kuti spindle yese ive nani. Mutengo, mutoro, preload, lubrication, kuvhunduka kurodha, spindle dhizaini, kumhanya kwechinangwa, uye kuoma kunodiwa kunofanirwa kutariswa.

Kutakura Hurongwa Kunokosha Zvakangofanana Nekuzvitakura Kwacho

Machina-chishandiso spindles haawanzovimbika pane imwe fani mukuzviparadzanisa. Angular contact bearings anowanzo kuisirwa seakafananidzwa mapeya kana seti. Kurongeka kunotarisa kuti spindle inobata sei axial mutoro, radial mutoro, chinguva chidiki, kuoma, uye kuwedzera kwemafuta.
