I-worm shaft, eyaziwa nangokuthi i-worm screw, iyithuluzi elisetshenziselwa ukudlulisa ukunyakaza okuzungezayo phakathi kwamashafti amabili angefani. Iqukethe induku eyi-cylindrical ene-groove e-spiral noma intambo ebusweni bayo. Igiya lezikelemu, ngakolunye uhlangothi, liwuhlobo lwegiya elifana nesikulufu, elinemiphetho enamazinyo elixhunywe ne-spiral groove ye-worm shaft ukudlulisa amandla.
Lapho i-worm shaft izungeza, i-spiral groove ihambisa igiya lezikelemu, lona elinyakazisa imishini exhunyiwe. Lo mshini unikeza izinga eliphezulu lokudluliswa kwetorque, okuyenza ilungele imisebenzi edinga ukunyakaza okunamandla nokunensa, njengasemishinini yezolimo.
Enye inzuzo yokusebenzisa i-worm shaft negiya lezikelemu ku-gearbox wezolimo amandla azo okwehlisa umsindo nokudlidliza. Lokhu kungenxa yomklamo oyingqayizivele ovumela ukushelela nokuhamba kahle kwemishini. Lokhu kubangela ukuthi umshini uguge kancane, kukhuphule ukuphila kwawo futhi kwehlise nezindleko zokuwulungisa.
Enye inzuzo yikhono labo lokwandisa ukusebenza kahle kokudluliswa kwamandla. I-engeli ye-spiral groove ku-worm shaft inquma isilinganiso segiya, okusho ukuthi umshini ungaklanywa ngokuqondile ukuvumela isivinini esithile noma ukuphuma kwe-torque. Lokhu kukhuphuka kokusebenza kahle kubangela ukonga kukaphethiloli okuthuthukisiwe kanye nokuncipha kokusetshenziswa kwamandla, okuholela ekugcineni ekongeni okukhulu.
Sengiphetha, ukusetshenziswa kwe-worm shaft kanye negiya lezikelemu ku-gearbox yezolimo kudlala indima ebalulekile emishinini yezolimo ephumelelayo nesebenzayo. Idizayini yabo eyingqayizivele ivumela ukusebenza okuthule nokushelelayo kuyilapho ihlinzeka ngokusebenza kahle kokudluliswa kwamandla, ekugcineni okuholela embonini yezolimo esimeme futhi enenzuzo.
