Magiya a nyongolotsi ndi zida zotumizira mphamvu zomwe zimagwiritsidwa ntchito ngati zochepetsera kwambiri kuti zisinthidwe komwe kumazungulira ma shaft ndikuchepetsa liwiro ndikuwonjezera torque pakati pa mitsinje yozungulira yosafanana. Amagwiritsidwa ntchito pamiyendo yokhala ndi nkhwangwa zosadutsana, zopindika. Chifukwa mano a ma meshing giya amadutsana, magiya a nyongolotsi sagwira ntchito poyerekeza ndi ma drive ena, koma amatha kutsitsa mwachangu m'malo ophatikizika kwambiri motero amakhala ndi ntchito zambiri zamafakitale. M'malo mwake, zida za nyongolotsi zitha kugawidwa ngati zopindika limodzi ndi ziwiri, zomwe zimafotokozera ma geometry a mano a meshed. Magiya a nyongolotsi akufotokozedwa apa limodzi ndi kukambirana za momwe amagwirira ntchito komanso momwe amagwiritsidwira ntchito.

Zida za cylindrical worm

Mawonekedwe ofunikira a nyongolotsiyo ndi choyikapo choyikapo chomwe magiya a spur amapangira. Mano otsekera amakhala ndi makoma owongoka koma akagwiritsidwa ntchito popanga mano osasowekapo amatulutsa mtundu wodziwika bwino wa dzino wopindika wa zida za involute spur. Dzino la mphinjilili limakhala lozungulira thupi la nyongolotsi. Kukweretsa gudumu la nyongolotsi amapangidwa ndizida za helicalmano odulidwa pakona yomwe ikufanana ndi dzino la nyongolotsi. Maonekedwe a spur weniweni amangochitika mkatikati mwa gudumu, pamene mano amapindika ndikukuta nyongolotsiyo. Kuchita kwa meshing kumakhala kofanana ndi rack yoyendetsa pinion, kupatulapo kumasulira kwa rack kumasinthidwa ndi kayendedwe ka mphutsi. Kupindika kwa mano a magudumu nthawi zina kumatchedwa kuti "pakhosi."

Nyongolotsi zimakhala ndi ulusi umodzi kapena zinayi (kapena kuposerapo), kapena zoyambira. Ulusi uliwonse umalowetsa dzino pa gudumu la nyongolotsi, lomwe lili ndi mano ambiri ndi m'mimba mwake mokulirapo kuposa nyongolotsi. Nyongolotsi zimatha kutembenukira kumbali zonse. Mawilo a nyongolotsi nthawi zambiri amakhala ndi mano osachepera 24 ndipo kuchuluka kwa ulusi wa nyongolotsi ndi mano apamagudumu kuyenera kupitilira 40. Nyongolotsi zimatha kupangidwa mwachindunji patsinde kapena padera ndi kutsetsereka patsinde pambuyo pake.
Zambiri zochepetsera mphutsi zimangodzitsekera, ndiye kuti, sangathe kuyendetsedwa ndi gudumu la nyongolotsi, mwayi muzochitika zambiri monga kukweza. Pomwe kuyendetsa kumbuyo kuli chizolowezi chofunidwa, geometry ya nyongolotsi ndi gudumu zitha kusinthidwa kuti zilole (nthawi zambiri zimafuna kuyambika kambiri).
Kuthamanga kwa mphutsi ndi gudumu kumatsimikiziridwa ndi chiwerengero cha mano a gudumu ndi ulusi wa nyongolotsi (osati ma diameter awo).
Chifukwa chakuti nyongolotsi imawona kuwonongeka kwambiri kuposa gudumu, nthawi zambiri zinthu zosiyana zimagwiritsidwa ntchito pamtundu uliwonse, monga nyongolotsi yolimba yoyendetsa gudumu lamkuwa. Mawilo a pulasitiki a nyongolotsi amapezekanso.

Magiya a nyongolotsi imodzi ndi iwiri

Kuphimba kumatanthawuza momwe mano a nyongolotsi amakutira pang'ono pa nyongolotsi kapena mano a nyongolotsi amakutira pang'ono gudumu. Izi zimapereka malo olumikizana nawo. Chovala cha nyongolotsi chokhala ndi envelopu imodzi chimagwiritsa ntchito nyongolotsi ya cylindrical kumanga mano apakhosi a gudumu.
Pofuna kukhudza kwambiri dzino, nthawi zina nyongolotsiyo imadulidwa pakhosi - yooneka ngati hourglass - kuti igwirizane ndi kupindika kwa gudumu la nyongolotsi. Kukonzekera uku kumafuna kuyika bwino kwa axial kwa nyongolotsi. Magiya a nyongolotsi zokwiritsa kawiri ndizovuta ku makina ndipo amawona ntchito zochepa kuposa magiya a nyongolotsi omwe amaphimba limodzi. Kupita patsogolo kwa makina kwapangitsa kuti mapangidwe a envelopu awiri akhale othandiza kuposa momwe zinalili kale.
Magiya odutsa axis helical nthawi zina amatchedwa magiya osaphimba nyongolotsi. Chingwe cha ndege chikhoza kukhala chopanda envelopu.

Mapulogalamu

Ntchito yodziwika bwino yochepetsera maworm-gear ndi ma driver-conveyor lamba pomwe lamba amayenda pang'onopang'ono pokhudzana ndi mota, kupangitsa kuti mlanduwo ukhale wotsika kwambiri. Kukaniza kuyendetsa kumbuyo kudzera pa gudumu la nyongolotsi kungagwiritsidwe ntchito kupewa kutembenuka kwa lamba pamene chotengeracho chayima. Ntchito zina zomwe zimagwiritsidwa ntchito ndi ma valve actuators, ma jacks, ndi macheka ozungulira. Nthawi zina amagwiritsidwa ntchito polozera kapena ngati ma drive olondola a telescope ndi zida zina.
Kutentha kumakhala kodetsa nkhawa ndi magiya a nyongolotsi chifukwa kusunthaku kumatsetsereka ngati mtedza pa screw. Kwa makina oyendetsa ma valve, kayendetsedwe ka ntchito kamakhala kakang'ono ndipo kutentha kumatha mosavuta pakati pa ntchito zomwe zimachitika kawirikawiri. Kwa ma conveyor drive, ndikugwira ntchito mosalekeza, kutentha kumatenga gawo lalikulu pakuwerengera kapangidwe kake. Komanso mafuta apadera amalangizidwa kuti ayendetse mphutsi chifukwa cha kukanikiza kwakukulu pakati pa mano komanso kuthekera kwa kusweka pakati pa nyongolotsi zofananira ndi zida zamagudumu. Nyumba zoyendera mphutsi nthawi zambiri zimakhala ndi zipsepse zoziziritsa kuti zichotse kutentha kwamafuta. Pafupifupi kuzizirira kulikonse kungathe kukwaniritsidwa kotero kuti zinthu zotenthetsera za magiya a nyongolotsi ndizofunikira koma osati malire. Mafuta nthawi zambiri amalangizidwa kuti azikhala pansi pa 200 ° F kuti pakhale ntchito yogwira ntchito ya mphutsi iliyonse.
Kuyendetsa kumbuyo kumatha kapena sikungachitike chifukwa sikungodalira ma angles a helix komanso zinthu zina zocheperako monga mikangano ndi kugwedezeka. Kuti atsimikizire kuti izi zidzachitika nthawi zonse kapena sizidzachitika, wopanga makina oyendetsa nyongolotsi ayenera kusankha ma angles a helix omwe ali otsetsereka mokwanira kapena osaya mokwanira kuti apitirire mitundu inayi. Mapangidwe anzeru nthawi zambiri amalimbikitsa kuphatikizira mabuleki osafunikira ndi ma drive odzitsekera pomwe chitetezo chili pachiwopsezo.
Zida za mphutsi zimapezeka monga mayunitsi okhala ndi nyumba komanso ngati zida. Magawo ena amatha kugulidwa ndi ma servomotors ophatikizika kapena ngati mapangidwe othamanga.
Nyongolotsi zolondola mwapadera ndi mitundu ya zero-backlash zilipo pazogwiritsa ntchito zomwe zikuchepetsa kulondola kwambiri. Mabaibulo othamanga kwambiri amapezeka kuchokera kwa opanga ena.
