Amagiya ezikelemu ayizingxenye zokudlulisa amandla ezisetshenziswa kakhulu njengokunciphisa izinga eliphezulu lokushintsha indlela yokujikeleza kweshafu nokunciphisa isivinini nokwandisa i-torque phakathi kwama-shaft ajikelezayo angalingani. Asetshenziswa kuma-shaft anezingqimba ezingaphambani, eziqondile. Ngenxa yokuthi amazinyo amagiya e-meshing ayashelelana, amagiya ezikelemu awasebenzi kahle uma kuqhathaniswa namanye ama-drive egiya, kodwa angakhiqiza ukwehla okukhulu kwesivinini ezindaweni ezincane kakhulu futhi ngenxa yalokho anezinhlelo eziningi zezimboni. Empeleni, amagiya ezikelemu angahlukaniswa njenge-single-and-double-enveloping, echaza i-geometry yamazinyo ane-mesh. Amagiya ezikelemu achazwa lapha kanye nengxoxo yokusebenza kwawo kanye nezinhlelo zokusebenza ezivamile.

Amagiya ezikelemu eziyisilinda

Uhlobo oluyisisekelo lwesibungu yi-involute rack lapho kukhiqizwa khona amagiya e-spur. Amazinyo e-rack anezindonga eziqondile kodwa uma esetshenziswa ukukhiqiza amazinyo ezindaweni ezingenalutho zamagiya akhiqiza uhlobo olujwayelekile lwamazinyo agobile lwegiya le-involute spur. Lolu hlobo lwamazinyo e-rack lujikeleza umzimba wesibungu. Ukuhlangana isondo lesibungu yakhiwe yiigiya eliyindilingaAmazinyo asikwe nge-engeli ehambisana ne-engeli yezinyo lezibungu. Ukuma kwe-spur yangempela kwenzeka kuphela engxenyeni ephakathi yesondo, njengoba amazinyo egoba ukuze amboze i-worm. Isenzo se-meshing sifana nesomugqa oshayela i-pinion, ngaphandle kokuthi ukunyakaza kokuhumusha kwe-rack kuthathelwa indawo ukunyakaza okujikelezayo kwe-worm. Ukugoba kwamazinyo esondo ngezinye izikhathi kuchazwa ngokuthi “umphimbo.”

Izikelemu zizoba nentambo eyodwa noma ezine (noma ngaphezulu), noma iziqalo. Intambo ngayinye ibamba izinyo esondweni lezikelemu, elinamazinyo amaningi futhi ububanzi obukhulu kakhulu kunezikelemu. Izikelemu zingaphenduka kunoma iyiphi indlela. Amasondo ezikelemu ngokuvamile anamazinyo okungenani angu-24 futhi inani lezikelemu namazinyo ezikelemu ngokuvamile kufanele libe ngaphezu kuka-40. Izikelemu zingenziwa ngqo emgodleni noma ngokwehlukana bese zifakwa emgodleni kamuva.
Ama-worm-gear reducer amaningi ngokwemfundiso ayazikhiya ngokwawo, okungukuthi, awakwazi ukuqhutshwa yi-worm wheel, okuyinzuzo ezimweni eziningi njengokuphakamisa. Lapho i-back-drive kuyisici esifiselekayo, i-geometry ye-worm ne-wheel ingashintshwa ukuze ikuvumele (ngokuvamile idinga ukuqala kaningi).
Isilinganiso sejubane le-worm nesondo sinqunywa yisilinganiso senani lamazinyo esondo nezintambo ze-worm (hhayi ububanzi bazo).
Ngenxa yokuthi i-worm ibona ukuguguleka okukhulu kunesondo, ngokuvamile kusetshenziswa izinto ezingafani kuzo zonke, njengesibungu sensimbi esiqinile esiqhuba isondo lethusi. Amasondo e-worm epulasitiki nawo ayatholakala.

Amagiya ezikelemu ezimboza zodwa nezimboza kabili

Ukumboza kubhekisela endleleni amazinyo esondo lesibungu amboza ngayo ingxenye yesibungu noma amazinyo esibungu amboza ingxenye yesibungu. Lokhu kunikeza indawo enkulu yokuxhumana. Igiya lesibungu elimboza elilodwa lisebenzisa isibungu esiyisilinda ukuze lihlanganise amazinyo anesinqe esondo.
Ukuze kunikezwe indawo yokuthintana kwamazinyo okukhulu nakakhulu, ngezinye izikhathi i-worm ngokwayo igobile -- imise okwe-hourglass -- ukuze ivumelane nokugoba kwesondo le-worm. Lokhu kulungiselelwa kudinga ukubekwa kwe-axial ngokucophelela kwe-worm. Amagiya e-worm amboza kabili ayinkimbinkimbi emshinini futhi abonakala ukusetshenziswa okumbalwa kunegiya le-worm elimboza elilodwa. Intuthuko ekusetshenzisweni kwemishini yenze imiklamo emboza kabili yaba usizo kakhulu kunangaphambili.
Amagiya e-helical axhumene ne-cross-axis ngezinye izikhathi abizwa ngokuthi amagiya e-worm angambozi. I-aircraft clamp cishe ingaba umklamo ongambozi.

Izicelo

Isicelo esivamile sama-worm-gear reducers yi-belt-conveyor drives njengoba ibhande lihamba kancane uma kuqhathaniswa nemoto, okwenza kube nesidingo sokunciphisa isilinganiso esiphezulu. Ukumelana nokushayela emuva ngesondo le-worm kungasetshenziswa ukuvimbela ukuguqulwa kwebhande lapho i-conveyor ima. Ezinye izinhlelo zokusebenza ezivamile zise-valve actuators, ama-jack, kanye nama-circular saw. Ngezinye izikhathi zisetshenziselwa ukukhomba noma njenge-precision drives zama-telescopes nezinye izinsimbi.
Ukushisa kuyinkinga ngamagiya ezikelemu njengoba ukunyakaza empeleni kushelela njengenati esikulufini. Ku-actuator ye-valve, umjikelezo womsebenzi cishe uzoba nezikhawu futhi ukushisa cishe kunyamalale kalula phakathi kokusebenza okungajwayelekile. Ku-conveyor drive, okungenzeka kube nokusebenza okuqhubekayo, ukushisa kudlala indima enkulu ekubalweni komklamo. Futhi, kunconywa amafutha akhethekile okushayela izikelemu ngenxa yokucindezela okuphezulu phakathi kwamazinyo kanye nokwenzeka kokuqhekeka phakathi kwezinto ezingafani zezikelemu namasondo. Izindawo zokushayela izikelemu zivame ukufakwa amaphiko okupholisa ukuze kususwe ukushisa emafutheni. Cishe noma yiliphi inani lokupholisa lingafinyelelwa ngakho izici zokushisa zamagiya ezikelemu ziyizinto okufanele zicatshangelwe kodwa akuwona umkhawulo. Amafutha ngokuvamile anconywa ukuthi ahlale ngaphansi kuka-200°F ukuze kube nokusebenza okuphumelelayo kwanoma yikuphi ukushayela izikelemu.
Ukushayela emuva kungenzeka noma kungenzeki njengoba kuncike hhayi kuphela kuma-engeli e-helix kodwa nakwezinye izinto ezingabalwa kangako njengokungqubuzana nokudlidliza. Ukuqinisekisa ukuthi kuzohlala kwenzeka noma kungenzeki, umklami we-worm-drive kumele akhethe ama-engeli e-helix aqine ngokwanele noma angajulile ngokwanele ukuze anqobe lezi ezinye izinto eziguquguqukayo. Umklamo ohlakaniphile uvame ukusikisela ukufaka amabhuleki angafuneki kanye nama-drive azikhiyayo lapho ukuphepha kusengozini.
Amagiya ezikelemu ayatholakala kokubili njengamayunithi ahlala kanye namasethi amagiya. Amanye amayunithi angathengwa ngama-servomotor ahlanganisiwe noma njengemiklamo yesivinini esiningi.
Izimpungushe ezikhethekile zokunemba kanye nezinguqulo ze-zero-backlash ziyatholakala ezinhlelweni zokusebenza ezihilela ukunciphisa ukunemba okuphezulu. Izinguqulo zesivinini esiphezulu ziyatholakala kwabanye abakhiqizi.
