Linear Motor vs. Ball Screw Performance

Kuyerekeza Kwachangu

Pankhani ya liwiro,injini ya mzereali ndi mwayi ndithu, liniya galimoto liwiro mpaka 300m/mphindi, mathamangitsidwe 10g; mpira wononga liwiro la 120m/mphindi, mathamangitsidwe 1.5g. injini ya linear ili ndi mwayi waukulu poyerekeza liwiro ndi kuthamanga, injini ya mzere mu njira yabwino yothetsera vuto la kutentha, liwiro lidzawongoleredwa bwino, pamene rotary servo motor + screw screw Kuchepetsa liwiro kumakhala kovuta kupititsa patsogolo.

Liniya motor ilinso ndi mwayi wokwanira pakuyankhidwa kosunthika chifukwa cha kuyenda kwa inertia, chilolezo komanso zovuta zamakina. Chifukwa cha kuyankha kwake mwachangu komanso liwiro lalikulu, imatha kukwanitsa kuthamanga kwambiri nthawi yomweyo poyambira ndikuyimitsa mwachangu ikathamanga kwambiri. Kuthamanga kumatha kufika 1:10000.

Kuyerekezera Kolondola

Chifukwa makina oyendetsa amangochepetsa vuto la interpolation hysteresis, kulondola kwa malo, kulondola kwa kubalana, ndi kulondola kwathunthu kwa injini ya mzere, yomwe imayang'aniridwa ndi chidziwitso cha malo, idzakhala yapamwamba kuposa ya rotary servo motor + mpira screw, ndipo n'zosavuta kukwaniritsa. Kulondola kwamayimidwe a mota yama mzere kumatha kufika 0.1μm. rotaryinjini ya servo+ wononga mpira ukhoza kufika 2 ~ 5μm, ndipo umafunika CNC - servo motor - cholumikizira chopanda msoko - thrust bear - njira yozizira -mkulu mwatsatanetsatane anagubuduza kalozera- chosungira mtedza - tebulo lotsekedwa kuzungulira gawo lonse la dongosolo lonse liyenera kukhala lopepuka komanso kulondola kwa magalasi kuyenera kukhala kwakukulu. Kuti tikwaniritse kukhazikika kwapamwamba, rotary servo motor + mpira screw iyenera kukhala yapawiri-axis drive, liniya yamagetsi yazigawo zotentha kwambiri, iyenera kutenga njira zoziziritsa zamphamvu, kuti mukwaniritse cholinga chomwecho, mota ya liniya iyenera kulipira mtengo wokulirapo.

Kuyerekeza Mtengo

Mtengo, mtengo wamakina oyendera mizere ndi wokwera pang'ono, ndichifukwa chake ma mota amzere amagwiritsidwa ntchito kwambiri.

Kuyerekeza kwa Kugwiritsa Ntchito Mphamvu

Linear motor kuti ipereke torque yomweyi pomwe kugwiritsa ntchito mphamvu kumapitilira kuwirikiza kawiri servo motor +mpira wodula, rotary servo motor + mpira screw ndi mphamvu yopulumutsa mphamvu yowonjezera mphamvu zowonjezera zigawo.

Kugwiritsa Ntchito Kufananiza

M'malo mwake, liniya mota ndi rotary servo mota + mpira wononga mitundu iwiri ya pagalimoto, ngakhale iliyonse ili ndi zabwino ndi zovuta zake, koma onsewa ali ndi njira yabwino kwambiri yogwiritsira ntchito zida zamakina a CNC.

Linear motor drive ili ndi maubwino apadera m'magawo otsatirawa a zida za CNC:

(1) kuthamanga kwambiri, kuthamanga kwambiri, kuthamanga kwambiri, kuchuluka kwa kupanga kwakukulu, komanso kufunikira koyika ma frequency apamwamba, kusintha kukula kwa liwiro ndi komwe kumasinthasintha pafupipafupi pamwambowu. Mwachitsanzo, mzere wopanga magalimoto ndi makampani a IT, kulondola komanso kupanga nkhungu zovuta, etc.

(2) Large kopitilira muyeso-atali sitiroko mkulu-liwiro Machining Center, Azamlengalenga kupanga makampani mu aloyi kuwala, woonda-mipanda, zitsulo kuchotsa mlingo wa chigawo chonse hollowing processing. Mwachitsanzo, United States CINCIATI Hyper Mach Machining Center (46m), Japan's MAZAK HYPERSONIC1400L Ultra-high-speed Machining Center.

(3) Pamafunika kusinthasintha kwakukulu, kuthamanga kotsika, kutsata kwachangu, komanso kuyika kwachangu kwambiri. Mwachitsanzo, m'badwo watsopano wa mkulu-ntchito CNC zida makina makina makina akuimiridwa ndi Sodick, CNC kopitilira muyeso-mwatsatanetsatane makina makina, m'badwo watsopano wa CNC crankshaft akupera makina, cam mphero makina, CNC sanali zozungulira lathe, etc.

(4) katundu wopepuka, zida zapadera za CNC. Mwachitsanzo, Germany DMG's DML80FineCutting laser engraving and punching machine, Belgium LVD's AXEL3015S laser cutting machine, MAZAK's HyperCear510 high-speed laser processing machine.
