Umehluko phakathi kwe-Spindle Motor kanye ne-Servo Motor, Zingasetshenziswa Ngasikhathi sinye

   

Emkhakheni wezimboni, izinjini zingamandla okushayela abalulekile emishini ehlukahlukene. Ama-spindle motors, ama-servo motors nama-linear motors ayizinhlobo ezimbalwa ezijwayelekile zamamotho, ngayinye inezici zayo kanye nobubanzi bokusebenza.

Umehluko phakathi kwama-spindle motors nama-servo motors

Ama-spindle motors nama-servo motors zombili izinhlobo ezijwayelekile zamamotho emkhakheni wokulawulwa kwezimboni, kepha ahluke kakhulu ngokuya ngemigomo yokuklama kanye nezimo zokusebenzisa.

I-spindle motor iyijubane eliphezulu, i-torque ephezulu ye-linear drive motor, evame ukusetshenziswa kumathuluzi omshini, izixube namanye amadivaysi okudlulisa. Izici eziyinhloko zama-spindle motors yijubane elizinzile lokujikeleza, ukuphendula okusheshayo nokunemba okuphezulu, okungahlangabezana nezidingo zejubane eliphezulu, ukunemba okuphezulu nokusebenza kahle okuphezulu.

I-Servo motor, ngakolunye uhlangothi, iwuhlobo lwemoto enesikhundla, isivinini kanye ne-torque njengethagethi yokulawula, evame ukusetshenziswa ekulawuleni okuzenzakalelayo, amarobhothi ezimboni, imishini yokuphrinta neminye imikhakha. Izici eziyinhloko zama-servo motors ukunemba okuphezulu, ukusabela okusheshayo, ukunemba kokulawula okuphezulu, futhi angabona ukulawula okunamandla okunembe.

Ama-spindle motors nama-servo motors adlala izindima ezihlukene kumathuluzi omshini we-CNC, okuholela ekwehlukeni kokuklama nokusebenza kwawo. Umsebenzi oyinhloko we-spindle motor ukushayela i-spindle yethuluzi lomshini futhi unikeze amandla amakhulu okusika umshini. Ngakho-ke, inkomba eyinhloko yokuphuma kwemoto yokuphotha amandla (kW) ukuze ihlangabezane nezidingo zomshini womshini. Ama-motor anjalo ngokuvamile adinga ukuba namandla amakhulu okukhiphayo, kanye nebanga elibanzi lejubane ukuze azivumelanise nezinto ezihlukene zomshini kanye nezidingo zenqubo.

Ngokuphambene, ama-servo motors kumathuluzi omshini we-CNC anesibopho esikhulu sokushayela ithebula lomshini noma imagazini yamathuluzi nezinye izingxenye ezihambayo ukuze kuzuzwe ukulawula okunembayo kokususa. Inkomba yokuphumayo yama-servo motors ikakhulukazi i-torque (Nm), okubangelwa ukuthi ama-servo motors adinga ukujikeleza ukuze ashayele ezinye izingxenye ukuze zisebenze, futhi i-torque iyinkomba eyinhloko yokukala leli khono lokushayela. Ama-Servo motors ngokuvamile asebenzisa isistimu yokulawula iluphu evaliwe, ekwazi ukulungisa ngokuqhubekayo okukhiphayo ngokuya ngezimpawu zempendulo ukuze ibone indawo eqondile nokulawula isivinini.

Izimo zesicelo se-spindle motor kanye ne-servo motor

Njengoba i i-spindle motor kanye Izici ze-servo motor kanye nezinzuzo zihlukile, ngakho-ke izimo zabo zohlelo lokusebenza ekulawuleni izimboni nazo zihlukile.

Ama-spindle motors avame ukusetshenziswa kumathuluzi omshini, umshini wokunyathelisa, ama-mixers nama-grinders, futhi afaneleka kumadivayisi okudlulisela adinga isivinini esikhulu, ukunemba okuphezulu nokusebenza kahle okuphezulu. Ama-spindle motors ngokuvamile alawulwa yi-fixed-frequency noma i-variable-frequency control, futhi i-torque ephumayo yesistimu yokushayela ilawulwa ngokulawula isivinini se-motor.

Ama-Servo motors, ngakolunye uhlangothi, avame ukusetshenziswa ekulawuleni okuzenzakalelayo, amarobhothi ezimboni, okokuphrinta, okokufaka impahla kanye neminye imikhakha ukuze kuzuzwe isikhundla esinembayo nokulawula isivinini. Ama-Servo motors ngokuvamile asebenzisa izilawuli ze-servo ukulawula indawo nesivinini semoto, impendulo yesikhathi sangempela phakathi kwendawo yangempela kanye nokuchezuka kwendawo okuqondiwe kuyo, kanye ne-algorithm ye-PID yokulungiswa okuguquguqukayo.

I-spindle motor kanye ne-servo motor ingasetshenziswa ngasikhathi sinye

Ekulawulweni kwezimboni, i-spindle motor kanye ne-servo motor ingasetshenziswa ngokuhlangana ngokuya ngezidingo ezithile. Isibonelo, kumathuluzi omshini we-CNC, ama-spindle motors ngokuvamile asetshenziselwa ukushayela i-spindle, kuyilapho i-servo motor isetshenziselwa ukushayela i-axis yokuphakelayo.

Kumele kuqashelwe ukuthi ukulawulwa kwama-spindle motors kanye nama-servo motors kudinga ukulawula okunembile kokuvumelanisa ukuze kuqinisekiswe ukuzinza nokunemba kwalo lonke uhlelo. Ngaphezu kwalokho, lapho ulungiselela i-spindle motor kanye ne-servo motor, kuyadingeka ukuthi ukhethe futhi uzifanise ngokuya ngesidingo sangempela namapharamitha womshini ukuze uthole umphumela wokulawula ongcono kakhulu.

Ama-spindle motors nama-servo motors ayizinhlobo ezijwayelekile zamamotho kulawulo lwezimboni, futhi anomehluko osobala emigomeni yokuklama kanye nezimo zohlelo lokusebenza. Ezinhlelweni ezisebenzayo, zingasetshenziswa zihlangene ngokuya ngesidingo, kodwa ukulawulwa kokuvumelanisa okunembayo kuyadingeka ukuze kuqinisekiswe ukuzinza nokunemba kwalo lonke uhlelo.

Umehluko omkhulu phakathi kwama-spindle motors nama-servo motors ubonakala ezimweni zohlelo lokusebenza, izidingo zokusebenza nezici zokukhipha. Ama-spindle motors aklanyelwe isivinini esikhulu kanye nokuphuma kwamandla njalo, futhi asetshenziselwa kakhulu ukushayela ama-spindle amathuluzi omshini; ama-servo motors agcizelela isikhundla esiqondile, isivinini kanye nokulawula i-torque, futhi afanele izinhlelo zokuphakela amathuluzi omshini kanye nemishini ezishintshayo.

Ukuqhathaniswa Komehluko Oyinhloko

Izinjongo zokuklama kanye nezimo zohlelo lokusebenza.

Ama-spindle motors:

Ilungiselelwe isivinini esikhulu sokujikeleza (imvamisa esingaphezu kuka-10,000 rpm) kanye nokuphuma kwamandla okungashintshi ukuze kuqinisekiswe amandla okusika anele agcinwa ngesivinini esihlukile.

Ikakhulukazi esetshenziswa emshinini wokuphotha ithuluzi lomshini, ukushayela i-workpiece noma ukuzungezisa ithuluzi lokusika ukucutshungulwa, idinga ukujwayela ukhuni, insimbi, ingilazi nezinye izinto.

I-Servo motor:

Ngomgomo oyinhloko wokubona ukusabela okusheshayo nokulawula ukunemba okuphezulu, inamandla okulungisa okuguquguqukayo kweleveli ye-millisecond futhi ingakwazi ukulawula ngokunembile indawo, isivinini kanye netorque.

Isetshenziswa kakhulu ohlelweni lokuphakelayo lwamathuluzi omshini (ithebula lokulawula noma ukunyakaza kwamathuluzi) namathuluzi ezishintshayo (njengamarobhothi, okokusebenza kwe-CNC), izidingo zokunemba komkhondo wokunyakaza ziphezulu kakhulu.

Izici zomphumela nezinkomba.

Ama-spindle motors asebenzisa amandla (kW) njengenkomba yokuphumayo, egcizelela izici zamandla ezingaguquki ebangeni elibanzi lejubane (lapho ijubane liphezulu, ithoshi yokuphuma iyancipha).

I-servo motor ithatha i-torque (Nm) njengenkomba yayo yokuphuma, igcizelela ukuphuma kwe-torque njalo kanye nekhono lokulayisha ngokweqile isikhathi esifushane (kuze kufike izikhathi ezi-3 ezilinganiselwe).

Imodi yesakhiwo nokulawula.

Isakhiwo se-spindle motor sinaka kakhulu ukuchithwa kokushisa nokuzinza, okuvamise ukuhlonyiswa ngesistimu yokupholisa uketshezi kanye nomklamo wokuthwala oqinisiwe, ukwamukela isilawuli sesivinini esivaliwe, senza kahle ukuphuma kwamandla okungaguquki.

Ama-Servo motors ngokuvamile aqukatha ama-encoder anokulungiswa okuphezulu (okufana nama-23-bit) nama-gearbox anembayo, asebenzisa isilawuli sendawo evaliwe, futhi asekele izinqubo zokuxhumana ezihlukahlukene ukuze kuzuzwe ukuvumelanisa kwe-microsecond.

Umehluko Kumapharamitha Obuchwepheshe Nezimfuneko Zokulungisa

Ama-spindle motors:

Amapharamitha wobuchwepheshe: amandla alinganiselwe, isivinini esiphezulu, isigaba sokufakelwa, njll., ngezikhathi ezimfushane zokulungisa (isb., ukugcwaliswa kwamafutha njalo ngamahora angama-500).

Servo motors:

Amapharamitha wobuchwepheshe: i-torque elinganiselwe, ibanga lesivinini, umthamo wokugcwala, njll., ngezikhawu zokulungisa ezinde (isb, ukuhlola ama-bearings njalo emahoreni angu-20,000).
