Kuthamanga kothamanga kwambiri sikungokhala ndi nambala yayikulu ya RPM pamasamba. Mu CNC spindle, liwiro logwiritsidwa ntchito limadalira dongosolo lonse lonyamula: kukula, kugubuduza-zinthu, kapangidwe ka mkati, ngodya yolumikizirana, kuyika, makonzedwe, kalasi yolondola, njira yothira mafuta, kukwanira, kuziziritsa, katundu, kuwongolera kuipitsidwa, ndi machitidwe amatenthedwe a spindle.
Ichi ndichifukwa chake ma fani awiri okhala ndi miyeso yofanana amatha kukhala ndi liwiro losiyana kwambiri, kukwera kwa kutentha, kuuma, phokoso, ndi moyo wautumiki. Ichi ndichifukwa chake chotengera chomwe chimagwira ntchito bwino pa 24,000 RPM mu nsonga imodzi sichingakhale choyenera kuthamanga komweko muzitsulo zazikulu, zodzaza kwambiri, zokongoletsedwa mosiyana.
Chotengera chachikulu: pendani ma spindle othamanga kwambiri ngati gawo la dongosolo. Maximum RPM ndi imodzi yokha. Speed factor, preload, lubrication, kukhazikika kwamafuta, kuuma, kuchuluka kwa katundu, makonzedwe onyamula, ndi mtundu woyika zimatsimikizira ngati kunyamula kumatha kugwira ntchito modalirika mu spindle yeniyeni.
Funsani za CNC Spindle Bearing Selection
Ma fani othamanga kwambiri ali ndi mapangidwe opangidwa kuti azigwira ntchito pa liwiro lozungulira kwambiri pomwe amawongolera kukangana, kutulutsa kutentha, centrifugal zotsatira, machitidwe opaka mafuta, kugwedezeka, komanso kuthamanga kolondola. Mu makina-chida ndi CNC spindle ntchito, zodziwika bwino mkulu-liwiro mayankho monga wapamwamba-mwatsatanetsatane angular kukhudzana mpira bheri , nthawi zambiri amaperekedwa monga machulukidwe seti ndi preload tafotokoza.
Kutengera kapangidwe ka spindle, mayendedwe othamanga kwambiri amatha kuphatikizidwa ndi ma cylindrical roller bearings kapena mitundu ina yonyamula kuti apereke chithandizo choyenera cha radial, kuthandizira kwa axial, kuuma, kukulitsa kutentha, komanso kuthamanga.
Ma 20 mm omwe akuthamanga pa 30,000 RPM ndi 80 mm akuthamanga pa 30,000 RPM samakumana ndi liwiro lomwelo. Chovala chachikulu chimakhala ndi liwiro laling'ono lozungulira komanso zotsatira za centrifugal. Pazifukwa izi, mainjiniya onyamula nthawi zambiri amagwiritsa ntchito liwiro lotengera liwiro lozungulira komanso kukhala ndi mainchesi.
Speed factor = n × d m
kumene n = liwiro lozungulira mu r/min
d m = (d + D) ÷ 2 , pomwe d ili ndi m'mimba mwake ndipo D ili ndi mainchesi akunja mu mm.
Mtengo wa n × d m ndi wothandiza poyerekeza kuopsa kwa liwiro, koma sichinali malire odutsa / kulephera konse. Mtengo wovomerezeka umadalira mtundu wonyamulira, khola, zinthu za mpira, kudzaza kale, kuthira mafuta, kuchotsa kutentha, katundu, kukwanira, ndi kapangidwe ka opanga.
Zinthu zing'onozing'ono zogudubuza ndi kukhathamiritsa kwa geometry yamkati zimatha kuchepetsa mphamvu yapakati komanso mikangano pa liwiro lalikulu. Komabe, kuchepetsa kukula kwa mpira kungasinthenso kuchuluka kwa katundu ndi kuuma. Mapangidwe othamanga kwambiri amaphatikiza kusinthana pakati pa liwiro, kulimba, kuchuluka kwa katundu, kukwera kwa kutentha, ndi moyo wofunikira wa spindle.
Mipira yolumikizana ndi angular imatumiza katundu pakona yolumikizana pakati pa mipira ndi njira zothamanga. Ma angle ang'onoang'ono olumikizana nthawi zambiri amalumikizidwa ndi mapangidwe othamanga kwambiri, pomwe ma angles akulu olumikizana amatha kupereka mphamvu yayikulu ya axial. Mbali yolondola iyenera kusankhidwa mozungulira katundu wa spindle, kuuma kwa axial, mawonekedwe a zida, kachitidwe kachitidwe, ndi liwiro la chandamale.
Osasankha ngodya yolumikizana ndi liwiro lokha. Kuthamanga kothamanga kwambiri kumatha kukhala chisankho cholakwika ngati spindle imafuna kulimba kwa axial kapena kutsika kwamphamvu kuposa momwe makonzedwe angaperekedwe.
Preload imachotsa kusewera kwamkati ndipo imatha kukonza kuuma kwa spindle ndikuyendetsa bwino. Koma kulemetsa kwambiri sikuli bwino nthawi zonse. Kudzaza kwambiri kumawonjezera kukhudzana kwamkati, kukangana, ndi kutentha, zomwe zingachepetse liwiro lofikira komanso moyo wobereka.

Sikuti ndizosankha zabwino koposa zonse zopota; mtengo, katundu, kudzaza, kudzoza, kuuma, ndi liwiro la ntchito zikadali zofunika.
Ayi. M'zinthu za spindle, 'hybrid ceramic ceramic' nthawi zambiri amatanthauza zinthu zogudubuza za ceramic-kawirikawiri mipira ya silicon nitride-yophatikizidwa ndi zitsulo zamkati ndi mphete zakunja.
Osati nthawi zonse. Kuchulukirachulukira kumatha kukulitsa kuuma kwa spindle, koma kumawonjezeranso katundu wamkati, kukangana, ndi kutentha. Ma spindles othamanga kwambiri nthawi zambiri amafunikira kusankhiratu mosamala kuti azitha kukhazikika komanso kutentha komanso kuthamanga.
Zonsezi zingakhale zoyenera. Mafuta amapereka makina osavuta ndipo amagwiritsidwa ntchito kwambiri popanga zopindika, pomwe mafuta opaka mpweya amatha kuthandizira ntchito zothamanga kwambiri popereka mafuta owongolera ochepa. Kusankha koyenera kumatengera kapangidwe kake, liwiro la chandamale, kutentha, kuzungulira kwa ntchito, ndi kamangidwe ka spindle.
Mafuta ochulukirapo amatha kuyambitsa kutentha kwambiri komanso kutentha kwambiri, makamaka panthawi yothamanga. Mapiritsi othamanga kwambiri amayenera kugwiritsa ntchito mtundu wa girisi ndikudzaza kuchuluka kwazomwe zimapangidwira kupanga ndi kupota.
