Yini i-pulley?

I-pulley iyisisetshenziswa esilula somshini noma umshini (ongaba ngokhuni, insimbi, noma ipulasitiki imbala) ehlanganisa intambo enwebekayo, intambo, iketango, noma ibhande elithwelwe onqenqemeni lwesondo. Isondo, elibuye libizwe ngokuthi isithungu noma isigubhu, lingaba yinoma yimuphi usayizi nobude.

 

I-pulley ingasetshenziswa yodwa noma ihlanganiswe ukudlulisa amandla nokunyakaza. Lawa madivayisi aklanywe kalula, anamandla asekela ukunyakaza kanye nokushuba kokuqondisa kabusha. Ngale ndlela, ngokusebenzisa amandla awo amancane, avumela ukuhamba kwezinto ezinkulu.

 

Uhlelo lwePulley

Nge-pulley eyodwa, isiqondiso kuphela samandla asetshenzisiwe singashintshwa. I-pulley ayishintshi nje kuphela isiqondiso samandla asetshenzisiwe kodwa futhi iphindaphinda amandla okufaka lapho amandla amabili noma ngaphezulu asetshenziswa ohlelweni. Uhlelo lwe-pulley lwakhiwe izingxenye ezintathu:

intambo

isondo

i-ekseli

Ama-Pulleys enza imisebenzi efana nokuphakamisa okusindayo nokunyakaza kube lula. Isebenzisa isondo nentambo ukuphakamisa imithwalo esindayo. Angakwazi ukushintshaniswa. Amapulangwe epulasitiki nawo ayatholakala emakethe futhi asetshenziselwa ukusiza ukuthwala izinyanda nemithwalo. Kuye ngokushintsha kwendlela kanye nobukhulu bamandla, zihlukaniswa ngezinhlobo ezahlukene.

 

Izinhlobo ezahlukahlukene zama-pulleys zisetshenziselwa izinhloso ezahlukahlukene. Kunjalo:

I-Pulley elungisiwe

I-Pulley ehambayo

I-Compound Pulley

Vimba futhi ubhekane nePulley

I-Cone Pulley

I-Swivel Eye Pulley

I-Eye Pulley Egxilile

 

Ukusebenza Okuwusizo kwama-Pulleys

Ama-pulleys ayesetshenziselwa ngokuyinhloko ukwenza umsebenzi wokuphakamisa izinto ezisindayo ube lula. I-pulley ingasetshenziswa yodwa noma ngokuhambisana namanye ama-pulley ukuthutha impahla. Okunye ukusetshenziswa kwayo okuningi yilezi:

Amapulangwe asetshenziselwa ukukhipha amanzi emithonjeni.

Ama-pulleys amaningi asetshenziselwa ukusebenza kwamakheshi nama-escalators.

Ama-pulleys asetshenziswa njalo kuma-derricks kawoyela futhi angasetshenziswa ekwandiseni izitebhisi.

Zivame ukusetshenziswa ekuthungeni nasekufakweni kwasolwandle.

Isetshenziselwa ukukhulisa inzuzo yemishini lapho isetshenziselwa imishini yezimboni nemishini esindayo.

Uhlelo lwe-pulley lusetshenziswa abagibeli bamatshe ukuze kube lula ukukhuphuka. I-pulley mechanism isiza ogibelayo ukuthi aye phezulu ngesikhathi edonsa intambo iye phansi.

Ama-Pulley asetshenziswa ezintweni eziningi zokuphakamisa izinsimbi ezihloselwe ukuzivocavoca. Asetshenziselwa ukulawula i-engeli lapho izisindo ziphakanyiswa khona kuyilapho kugcinwa izisindo endaweni efanele.
