Amagiya wezikelemu ayizingxenye zokudlulisa amandla ngokuyinhloko ezisetshenziswa njengokunciphisa isilinganiso esiphezulu ukushintsha isiqondiso sokujikeleza kwe-shaft kanye nokunciphisa isivinini kanye nokwandisa i-torque phakathi kwamashafti ajikelezayo angahambelani.Asetshenziswa ku-shafts enezimbazo ezingaphambanisi, ezi-perpendicular.Ngenxa yokuthi amazinyo amagiya ane-meshing ayashelela edlula amanye, amagiya wezikelemu awasebenzi kahle uma kuqhathaniswa namanye amagiya okushayela, kodwa angakhiqiza ukuncipha okukhulu kwesivinini ezindaweni ezihlangene kakhulu ngakho-ke abe nezinhlelo eziningi zokusebenza zezimboni.Empeleni, amagiya wezikelemu angahlukaniswa njenge-single- and double-enveloping, echaza i-geometry yamazinyo ane-meshed.Amagiya wezikelemu achazwe lapha kanye nengxoxo yokusebenza kwawo kanye nezicelo ezivamile.

Izikelemu ze-cylindrical worm

Ifomu eliyisisekelo lesikelemu i-involute rack okukhiqizwa ngayo amagiya e-spur.Amazinyo ama-rack anezindonga eziqondile kodwa uma esetshenziselwa ukukhiqiza amazinyo ezimbotsheni zamagiya akhiqiza uhlobo olujwayelekile lwamazinyo agobile lwegiya le-involute spur.Leli gama lezinyo le-rack lizungeza umzimba wesibungu.Ukukhwelana isondo lesikelemu yakhiwai-helical gearamazinyo asikwe nge-engeli ehambisana ne-engeli yezinyo lezikelemu.Ukuma kwe-spur yangempela kwenzeka kuphela engxenyeni emaphakathi yesondo, njengoba amazinyo ejika ukuze amboze isibungu.Isenzo se-meshing sifana naleso se-rack eshayela iphini, ngaphandle kokuthi ukunyakaza kokuhumusha kwe-rack kuthathelwa indawo ukunyakaza okujikelezayo kwesibungu.Ukugoba kwamazinyo esondo ngezinye izikhathi kuchazwa ngokuthi “okunomphimbo.”

Izikelemu zizoba okungenani nemicu eyodwa nezine (noma ngaphezulu), noma isiqalo.Intambo ngayinye ifaka izinyo esondweni lezikelemu, elinamazinyo amaningi kanye nobubanzi obukhulu kunolwembu.Izikelemu zingaphendukela kunoma iyiphi indlela.Amasondo ezikelemu ngokuvamile anamazinyo okungenani angama-24 kanti isamba sezintambo zezikelemu namazinyo angamasondo kufanele abe ngaphezu kwama-40.
Izinciphisi eziningi zegiya lezikelemu zizivalela ngokwazo, okusho ukuthi, azikwazi ukushayelwa emuva yisondo lezikelemu, okuyinzuzo ezimweni eziningi njengokuphakamisa.Lapho ukushayela emuva kuyisici esifiselekayo, ijiyomethri yesibungu nesondo ingase ishintshwe ukuze ikuvumele (okuvame ukudinga ukuqala okuningi).
Isilinganiso sesivinini sesikelemu nesondo sinqunywa isilinganiso senani lamazinyo esondo ukuya emiculweni yezikelemu (hhayi amadiamitha awo).
Ngenxa yokuthi isibungu sibona ukuguga okukhulu uma kuqhathaniswa nesondo, ngokuvamile kusetshenziswa izinto ezingafani kunto ngayinye, njengesikelemu sensimbi esiqinile esishayela isondo lethusi.Amasondo epulasitiki worm ayatholakala.

Igiya lezikelemu ezinezimvilophu ezilodwa kanye nezimbili

I-enveloping isho indlela amazinyo esondo lezikelemu asonga ngayo ingxenye yesibungu noma amazinyo ezikelemu asonga kancane esondo.Lokhu kunikeza indawo yokuxhumana enkulu.Igiya lezikelemu ezinemvilophu eyodwa lisebenzisa isibungu esiyicylindrical ukuze sihlanganise amazinyo asemqaleni wesondo.
Ukuze unikeze indawo enkulu yokuthinta izinyo, ngezinye izikhathi isikelemu ngokwaso siyaboshwa -- simise okwe-hourglass - ukufanisa ukugoba kwesondo lezikelemu.Lokhu kusetha kudinga ukuma ngokucophelela kwe-axial yesibungu.Amagiya ezikelemu avala kabili ayinkimbinkimbi emshinini futhi abona ukusetshenziswa okumbalwa kunamagiya ezikelemu ezivala imvilophi eyodwa.Intuthuko ekukhiqizeni imishini yenze imiklamo enemvilophu kabili yaba usizo kakhulu kunangaphambili.
Amagiya e-crossed-axis helical kwesinye isikhathi abizwa ngokuthi amagiya wezikelemu angavali.I-clamp yendiza kungenzeka ibe umklamo ongambozi.

Izinhlelo zokusebenza

Isicelo esijwayelekile sezinciphisi zegiya lezikelemu amabhande okuhambisa ibhande njengoba ibhande lihamba kancane uma kuqhathaniswa nenjini, okwenza icala libe nokwehliswa kwesilinganiso esiphezulu.Ukumelana nokushayela emuva ngesondo lezikelemu kungasetshenziswa ukuvimbela ukuhlehla kwebhande lapho isihambisi sima.Ezinye izinto ezisetshenziswayo ezijwayelekile kuma-valve actuators, ojeke, namasaha ayindilinga.Kwesinye isikhathi zisetshenziselwa ukukhomba noma njengamadrayivu anembayo wezibonakude nezinye izinsimbi.
Ukushisa kuyakhathaza ngamagiya ezikelemu njengoba ukunyakaza kushelela njengenadi esikulufini.Ku-actuator ye-valve, umjikelezo wemisebenzi kungenzeka ube nezikhawu futhi ukushisa cishe kuphele kalula phakathi kokusebenza okungajwayelekile.Kudrayivu ye-conveyor, ngokusebenza okungenzeka okuqhubekayo, ukushisa kudlala indima enkulu ezibalweni zedizayini.Futhi, izithambiso ezikhethekile ziyatuswa ukuze zishayele izikelemu ngenxa yokucindezela okukhulu phakathi kwamazinyo kanye nokwenzeka kokuba kube khona ukugaya phakathi kwezikelemu ezingafani kanye nezinto zamasondo.Izindlu zokushayela izikelemu zivame ukufakwa amaphiko okupholisa ukuze kukhishwe ukushisa emafutheni.Cishe noma yiliphi inani lokupholisa lingafinyelelwa ukuze izici ezishisayo zamagiya wezikelemu zicatshangelwe kodwa hhayi umkhawulo.Amafutha ngokuvamile atuswa ukuthi ahlale ngaphansi kuka-200°F ukuze kube nokusebenza okuphumelelayo kwanoma iyiphi i-worm drive.
Ukushayela emuva kungase kwenzeke noma kungenzeki ngoba akuncikile kuphela kuma-engeli e-helix kodwa nakwezinye izici ezingenakulinganiswa njengokungqubuzana nokudlidliza.Ukuqinisekisa ukuthi kuzohlala kwenzeka noma ngeke kwenzeke, umklami we-worm-drive kufanele akhethe ama-engeli e-helix okungenzeka akhuphukele ngokwanele noma angashoni ngokwanele ukuze akhiphe lezi ezinye eziguquguqukayo.Idizayini ehlakaniphile ivamise ukuphakamisa ukufaka amabhuleki angasebenzi kanye namadrayivu azikhiyayo lapho ukuphepha kusengozini.
Amagiya wezikelemu atholakala kokubili njengamayunithi ahlala endlini nanjengamagiya.Amanye amayunithi angathengwa ngama-servomotor abalulekile noma njengemiklamo enamasivinini amaningi.
Izikelemu ezinemba okukhethekile nezinguqulo ze-zero-backlash ziyatholakala ezinhlelweni ezibandakanya ukuncishiswa kokunemba okuphezulu.Izinguqulo zejubane eliphezulu ziyatholakala kwabanye abakhiqizi.
