Mpira Screw Drive

Ball Screw Drive ndi chida cholondola chamakina chotumizira chomwe chimatembenuza bwino kusuntha kozungulira kukhala koyenda mzere. Zimapangidwa ndi zomangira za mpira, mtedza, mipira, makina ozungulira, ndi zida zothandizira monga ma beya othandizira ndi zovundikira fumbi. Ball Screw Drive imagwiritsidwa ntchito kwambiri m'magawo monga zida zamakina a CNC, maloboti, zida zolondola, zida zakuthambo, ndi zina zambiri.

Mfundo yogwirira ntchito ya Ball Screw Drive imachokera pakugundana: pamwamba pa screw shaft imapangidwa ndi mipikisano yozungulira, ndipo pali ma groove ozungulira mkati mwa nati, ndi mipira yodzaza kusiyana pakati pa mipikisano iwiriyi. Pamene galimoto imayendetsa wononga kuti izungulire (kapena nati imayendetsedwa kuti izungulire ndi mphamvu yakunja), mpirawo umagudubuza mumsewu wozungulira ndikukankhira nati (kapena wononga) kuti ipange mzere wozungulira kumbali ya axial kupyolera mukugwedezeka. Njira yozungulira imawongolera mpirawo kuti ubwerere kuchokera kumapeto kwa msewu mpaka kumapeto koyambira, ndikupanga kuzungulira kotseka kuti kuwonetsetse kuyenda kosalekeza komanso kosasokonezeka.

Poyerekeza ndi ma sliding screw transmission, Ball Screw Drive ili ndi zabwino zambiri. Choyamba, ndi mkulu dzuwa. Kuthekera kwa ma sliding friction nthawi zambiri kumakhala 20% -40% yokha, pomwe zomangira za mpira zimadalira kugundana kuti zigwire bwino ntchito mopitilira 90%, kumachepetsa kutayika kwamagetsi komanso koyenera kusuntha{6}}liwiro komanso ma frequency apamwamba. Chachiwiri ndicholondola kwambiri. Kupyolera mwatsatanetsatane akupera, malo ake olondola akhoza kulamulidwa pa mlingo wa micrometer, ndi zolakwika zochepa zobwerezabwereza, zomwe zingathe kukwaniritsa zofunikira za chakudya cholondola ndi malo. Kuphatikiza apo, Ball Screw Drive imakhala ndi zovala zochepa komanso moyo wautali wautumiki, ndipo kukangana kumachepetsa kuvala kwachindunji pakati pa magawo. Kuphatikizidwa ndi dongosolo lopaka mafuta, limatha kuwonjezera moyo wautumiki.

Pano Patsamba ili, tikuyambitsa mndandanda wa Linear Ball Screws, mudzawona mapepala, zithunzi zopanga, makanema oyesa motere:

Komanso Mwalandiridwa kuti muwonere ma projekiti ambiri kapena kuchezera nyumba yathu yosungiramo makanema ndi Youtube: https://www.youtube.com/@tallmanrobotics

Kuyesa Makanema a Ball Screws kuchokera ku TallMan Robotic:

Zithunzi Zakulongedza ndi Kutumiza kwa Mpira Screws kuchokera ku TallMan Robotics:

Malinga ndi zofunikira pakugwiritsa ntchito, Ball Screw Drive ikhoza kugawidwa m'mitundu yosiyanasiyana: kufalikira kwakunja (mapangidwe osavuta, otsika mtengo) ndi kufalikira kwamkati (kulondola kwambiri, phokoso lotsika) molingana ndi njira yozungulira; Malinga ndi mulingo wolondola, wagawidwa mulingo wa C, mulingo wa D, mulingo wa E, ndi zina zotere, zomwe zikugwirizana ndi zolakwika zotsogola zosiyanasiyana; Malinga ndi pre tightening njira, akhoza kugawidwa mu nati umodzi popanda pre tightening, pawiri mtedza pre kumangitsa, etc., ntchito kuthetsa axial chilolezo ndi kusintha rigidity.

Pazogwiritsa ntchito, ndikofunikira kusankha Ball Screw Drive yokhala ndi magawo oyenerera kutengera kukula kwa katundu, kuthamanga kwa magwiridwe antchito, komanso kulondola kwa malo. Panthawi imodzimodziyo, kuyenera kuyang'aniridwa pa kulinganiza kwa parallelism, kusintha kwa axial clearance, ndi kukonza nthawi zonse poika makinawo kuti zitsimikizire kuti zikugwira ntchito kwa nthawi yayitali{1}zokhazikika. Monga gawo loyambira la makina amakono amakampani, Ball Screw Drive imapereka chithandizo chofunikira chaukadaulo popanga molondola komanso kuyendetsa makina.
