Bearing ya rivilo lerikulu a hi bearing ntsena leyi nga na nomboro leyikulu ya RPM eka datasheet. Eka spindle ya CNC, rivilo leri tirhisiwaka riya hi sisiteme ya bearing leyi heleleke: vukulu bya bearing, rolling-element material, dizayini yale ndzeni, contact angle, preload, lunghiselelo, tlilasi ya ku pakanisa, ndlela yo chela mafurha, ku ringanela, ku kufumela, ndzhwalo, vulawuri bya thyaka, na mahanyelo yo hisa ya spindle.
Leswi hi swona swi endlaka leswaku ti bearing timbirhi letingana ti dimensions leti fanaka tingava na vuswikoti byo hambana swinene bya rivilo, ku tlakuka ka mahiselo, ku tiya, mpfumawulo, na vutomi bya ntirho. Nakambe hi swona swi endlaka leswaku bearing leyi tirhaka kahle eka 24,000 RPM eka spindle yin’we yingava yinga ringanelanga eka rivilo leri fanaka eka spindle leyikulu, leyi rhwalekaka ngopfu, leyi cheriweke mafurha yohambana.
Key takeaway: kambela ti bearings ta spindle ta rivilo lerikulu tani hi xiphemu xa sisiteme. Maximum RPM i input yin’we ntsena. Speed factor, preload, lubrication, thermal stability, stiffness, load capacity, lunghiselelo ra bearing, na khwalithi yo veka swi endla leswaku bearing yinga tirha hiku tshembheka eka spindle ya xiviri.
Vutisa Hi Ku Hlawula Ka CNC Spindle Bearing
Ti bearing ta rivilo lerikulu i ti bearing designs leti antswisiweke ku tirha hi rivilo leri tlakukeke ro rhendzeleka loko tiri karhi ti lawula friction, ku tumbuluxiwa ka kuhisa, centrifugal effects, mahanyelo ya lubrication, vibration, na ku tsutsuma kahle. Eka switirhisiwa swa muchini-xitirhisiwa na CNC spindle, swintshuxo leswi tolovelekeke ngopfu swa rivilo lerikulu swi katsa ti super-precision angular contact ball bearings , leti talaka ku phakeriwa tanihi tisethi leti ringanisiweke leti nga na preload leyi hlamuseriweke.
Kuya hi architecture ya spindle, ti high-speed angular contact ball bearings tinga hlanganisiwa na ti cylindrical roller bearings kumbe tinxaka tin’wana ta ti bearing kuva tinyika balance leyi lavekaka ya radial support, axial support, stiffness, thermal expansion capability, na rivilo.
Bearing ya 20 mm leyi tsutsumaka hi 30,000 RPM na bearing ya 80 mm leyi tsutsumaka hi 30,000 RPM a yi hlangana na xiyimo xa rivilo lexi fanaka. Bearing leyikulu yina rivilo rale henhla ra rolling-element na switandzhaku swa centrifugal. Hi xivangelo lexi, vanjhiniyara va ti bearing vatala kutirhisa parameter ya rivilo leyi seketeriweke eka rivilo ro rhendzeleka na bearing mean diameter.
Xiphemu xa rivilo = n × d m
laha n = rivilo ro rhendzeleka hi r/min
d m = (d + D) ÷ 2 , laha d yi nga dyayimeta ya bore ya bearing kasi D yi nga dyayimeta ya le handle hi mm.
Nhlayo ya n × d m ya pfuna eka ku pimanisa ku tika ka rivilo, kambe ya ha ri mpimo wa ku hundza/ku tsandzeka wa misava hinkwayo. Nhlayo leyi pfumeleriwaka yiya hi nxaxamelo wa ti bearing, khege, swilo swa bolo, preload, ku cheriwa mafurha, ku susiwa ka kuhisa, ndzhwalo, ku ringanela, na data ya dizayini ya muendli.
Ti rolling elements letintsongo xikan’we na geometry yale ndzeni leyi antswisiweke swinga hunguta matimba ya centrifugal xikan’we na friction eka rivilo lerikulu. Hambiswiritano, ku hunguta vukulu bya bolo swinga tlhela swi cinca vuswikoti bya ndzhwalo xikan’we naku tiya. Xisweswo dizayini ya rivilo lerikulu yi katsa ku cincana exikarhi ka rivilo, ku tiya, vuswikoti byo rhwala, ku tlakuka ka mahiselo, na vutomi bya spindle lebyi lavekaka.
Ti angular contact ball bearings ti hundzisela ndzhwalo kuya hi contact angle exikarhi ka mabilomu na ti raceways. Ti contact angles letintsongo titala ku fambelanisiwa na ti design ta spindle ta rivilo lerikulu, kasi ti contact angles letikulu tinga nyika vuswikoti lebyikulu bya axial load. Angle leyinene yifanele ku hlawuriwa ku rhendzela ndzhwalo wo tsema wa spindle, xilaveko xa axial stiffness, tool interface, maendlelo ya bearing, na rivilo leri kongomisiweke.
U nga hlawuli contact angle kusuka eka rivilo ntsena. Bearing leyingana vuswikoti bya kahle swinene bya rivilo ra theoretical yingava nhlawulo wo biha loko spindle yi lava ku tiya swinene ka axial kumbe vuswikoti byo susumeta kutlula leswi lunghiselelo ringa swinyikaka.
Preload yi susa ku tlanga endzeni naswona yinga antswisa ku tiya ka spindle xikan’we naku tsutsuma kahle. Kambe preload yo tala a hi minkarhi hinkwayo yi antswaka. Preload yotala yi engetela ndzhwalo wa contact endzeni, friction, na kuhisa, leswinga hunguta rivilo leri fikelelekaka xikan’we na vutomi bya bearing.
