Iigiya ze-worm ziinxalenye zokuhambisa amandla ezisetyenziswa kakhulu njengokunciphisa umlinganiselo ophezulu ukutshintsha indlela yokujikeleza kwe-shaft kunye nokunciphisa isantya kunye nokwandisa i-torque phakathi kwee-shafts ezijikelezayo ezingahambelaniyo. Zisetyenziswa kwii-shafts ezinee-axes ezithe nkqo ezingadibaniyo, ezithe nkqo. Ngenxa yokuba amazinyo eegiya ze-meshing ayatyibilika, iigiya ze-worm azisebenzi kakuhle xa kuthelekiswa nezinye ii-drive zegiya, kodwa zinokwenza ukwehla okukhulu kwesantya kwiindawo ezincinci kakhulu kwaye ngenxa yoko zinezicelo ezininzi zoshishino. Ngokwenyani, iigiya ze-worm zinokuhlulwa njenge-single-and-double-enveloping, echaza i-geometry yamazinyo ane-mesh. Iigiya ze-worm zichazwe apha kunye nengxoxo yokusebenza kwazo kunye nezicelo eziqhelekileyo.

Iigiya zempethu ezizii-cylindrical

Uhlobo olusisiseko lwe-worm yi-involute rack apho kwenziwa khona ii-spur gears. Amazinyo e-rack aneendonga ezithe tye kodwa xa esetyenziselwa ukuvelisa amazinyo kwiindawo ezingenanto zegiya avelisa uhlobo oluqhelekileyo lwamazinyo ajijekileyo lwe-involute spur gear. Olu hlobo lwamazinyo e-rack lujikeleza umzimba we-worm. Ukudibana ivili lempethu yenziwe yiigiya yehelikoptaAmazinyo asikwe nge-engile ehambelana ne-engile yezinyo le-worm. Ubume bokwenyani be-spur buvela kuphela kwicandelo eliphakathi levili, njengoko amazinyo egoba ukuze agqume i-worm. Isenzo se-meshing sifana neso se-rack eqhuba i-pinion, ngaphandle kokuba intshukumo yokuguqula i-rack ithathelwa indawo yintshukumo ejikelezayo ye-worm. Ukugoba kwamazinyo evili ngamanye amaxesha kuchazwa njenge-"throated".

Iimpethu ziya kuba nomsonto omnye okanye ngaphezulu, okanye intambo enye ukuya kuthi ga kwezine (okanye ngaphezulu), okanye isiqalo. Umsonto ngamnye ubamba izinyo kwivili lempethu, elinamazinyo amaninzi kunye nobubanzi obukhulu kunempethu. Iimpethu zinokujika ziye nakweyiphi na indlela. Amavili empethu adla ngokuba namazinyo angama-24 ubuncinane kwaye isimbuku semisonto yempethu kunye namazinyo evili kufuneka sibe ngaphezu kwama-40. Iimpethu zingenziwa ngqo kwi-shaft okanye ngokwahlukeneyo kwaye zifakwe kwi-shaft kamva.
Ii-worm-gear reducers ezininzi ngokwethiyori ziyakwazi ukuzitshixa ngokwazo, oko kukuthi, azikwazi ukuqhutywa ngasemva livili le-worm, into eluncedo kwiimeko ezininzi ezifana nokuphakamisa. Apho i-back-drive iyimpawu efunekayo, i-geometry ye-worm kunye nevili inokulungiswa ukuze ivumeleke (idla ngokufuna ukuqala izihlandlo ezininzi).
Umlinganiselo wesantya se-worm kunye nevili umiselwa ngumlinganiselo wenani lamazinyo evili kwimisonto ye-worm (hayi ububanzi bayo).
Ngenxa yokuba i-worm ibona ukuguguleka okukhulu kunevili, kudla ngokusetyenziswa izinto ezahlukeneyo kuyo nganye, njenge-worm eqinileyo yentsimbi eqhuba ivili lebronze. Amavili e-worm eplastiki nawo ayafumaneka.

Iigiya zempethu ezigubungelayo zodwa nezigubungela kabini

Ukugquma kubhekisa kwindlela amazinyo evili leempethu ajikeleza ngayo inxalenye yempethu okanye amazinyo eempethu ajikeleza inxalenye yevili. Oku kubonelela ngendawo enkulu yokunxibelelana. Isixhobo seempethu esigqumayo esinye sisebenzisa impethu esisilinda ukunxibelelanisa amazinyo anemiqala yevili.
Ukuze inike umphezulu omkhulu wokuthintana kwamazinyo, ngamanye amaxesha i-worm ngokwayo inomphimbo -- imilo efana ne-hourglass -- ukuze ihambelane nokugoba kwevili le-worm. Olu seto lufuna indawo ebekwe ngononophelo ye-axial ye-worm. Ii-worm gears ezigubungela kabini ziyinkimbinkimbi kumatshini kwaye azinazo izicelo ezininzi kunee-worm gears ezigubungelayo enye. Inkqubela phambili ekusetyenzisweni kwemishini yenze uyilo lwe-worm gears ezigubungela kabini lube luncedo ngakumbi kunangaphambili.
Iigiya zehelical ezinqamlezileyo ngamanye amaxesha zibizwa ngokuba ziigiya zeworm ezingagqumiyo. I-aircraft clamp kusenokwenzeka ukuba ayilulo uyilo olungagqumiyo.

Izicelo

Isixhobo esiqhelekileyo sokunciphisa ii-worm-gear zii-belt-conveyor drives njengoko i-belt ihamba kancinci xa ithelekiswa ne-motor, nto leyo eyenza ukuba i-wind-driving ibe sezantsi kakhulu. Ukumelana nokubuyela umva kwi-worm wheel kunokusetyenziswa ukuthintela ukuguquka kwe-belt xa i-conveyor iyeka. Ezinye izicelo eziqhelekileyo zikwi-valve actuators, ii-jacks, kunye nee-circular saws. Ngamanye amaxesha zisetyenziselwa uku-indexing okanye njenge-precision drives zeeteleskopu kunye nezinye izixhobo.
Ubushushu buyinto exhalabisayo ngeegiya zeminyovu njengoko intshukumo ityibilika njengenati kwisikrufu. Kwi-actuator yevalvu, umjikelo womsebenzi unokuba mfutshane kwaye ubushushu bunokunyamalala ngokulula phakathi kwemisebenzi engaqhelekanga. Kwi-conveyor drive, mhlawumbi ngokusebenza okuqhubekayo, ubushushu budlala indima enkulu ekubalweni koyilo. Kwakhona, kucetyiswa ii-lubricants ezikhethekileyo kwii-worm drives ngenxa yoxinzelelo oluphezulu phakathi kwamazinyo kunye nokuba nokwenzeka kokuqhekeka phakathi kwezinto zeminyovu ezahlukeneyo kunye neevili. Iindawo zokugcina ii-worm drives zihlala zifakelwa ii-cooling fins ukuze kususwe ubushushu kwi-oyile. Phantse naluphi na ubuninzi bokupholisa bunokufezekiswa ngoko ke izinto zobushushu kwiigiya zeminyovu ziyinto eqwalaselwayo kodwa ayingomda. Iioyile zihlala zicetyiswa ukuba zihlale ngaphantsi kwama-200°F ukuze kubekho ukusebenza okusebenzayo kwayo nayiphi na i-worm drive.
Ukuqhuba ngasemva kusenokwenzeka okanye kungenzeki kuba kuxhomekeke kungekuphela nje kwii-engile ze-helix kodwa nakwezinye izinto ezingabalwanga kangako ezifana nokungqubana kunye nokungcangcazela. Ukuqinisekisa ukuba kuya kuhlala kwenzeka okanye akusoze kwenzeke, umyili we-worm-drive kufuneka akhethe ii-engile ze-helix ezithe nkqo ngokwaneleyo okanye ezingaphantsi ngokwaneleyo ukuze zithintele ezi zinto zimbi. Uyilo olukrelekrele ludla ngokucebisa ukuba kufakwe iibrake ezingafunekiyo kunye nee-self-locking drives apho ukhuseleko lusengozini.
Iigiya zemibungu ziyafumaneka zombini njengeeyunithi ezihlala abantu kunye neegiya. Ezinye iiyunithi zinokuthengwa ngee-servomotor ezidibeneyo okanye njengeedizayini zesantya ezininzi.
Iintlobo ezikhethekileyo ze-precision worms kunye neenguqulelo ze-zero-backlash ziyafumaneka kwizicelo ezibandakanya ukunciphisa ukuchaneka okuphezulu. Iintlobo ze-high speed ziyafumaneka kwabanye abavelisi.
