Mune mechanics, dhizaini ivhiri redenderedzwa rinotenderera nepakati axis.Pane groove pane circumferential pamusoro pevhiri rakatenderera.Kana tambo yakamonererwa mugero uye chero kumucheto kwetambo kudhonzwa nechisimba, kukweshana kuri pakati petambo nevhiri reround kuchaita kuti vhiri ritenderere richitenderedza akiso yepakati.Pulley chiredzo chakaremara chinogona kutendeuka.Basa guru repulley nderekudhonza mutoro, kushandura kutungamira kwesimba, simba rekutumira uye zvichingodaro.Muchina une mapulley akawanda unonzi "pulley block", kana "compound pulley".Iyo pulley block ine yakakura mabhenefiti mabhenefiti uye inogona kudhonza mitoro inorema.Mapulley anogona zvakare kushandiswa sezvikamu mumaketani kana mabhandi madhiraivha kuendesa simba kubva kune imwe inotenderera axis kuenda kune imwe.
Maererano nechinzvimbo chepakati chepakati chepulley kana ichifamba, pulley inogona kugoverwa mu "fixed pulley", "pulley inofamba";Iyo yepakati axis yeyakagadziriswa pulley yakagadziriswa, nepo iyo yepakati axis yekufamba pulley inogona kutamiswa, imwe neimwe ine zvayakanakira nezvayakaipira.Uye yakagadziriswa pulley uye inofambisa pulley musangano pamwe chete inogona kuumba pulley boka, pulley boka kwete chete kuchengetedza simba uye rinogona kushandura kutungamira kwesimba.
Pulley inoratidzika muchimiro chezivo point mufizikisi yekudzidzisa zvinhu zvejunior high school, izvo zvinoda mhinduro kumatambudziko akadai sekutungamira kwesimba, chinhambwe chekufamba kwetambo kupera uye mamiriro ebasa rakaitwa.

The pulley
Madiki saizi pulleys ane mitoro midiki (D<350mm) anowanzo gadzirwa kuita mapulley akasimba, achishandisa 15, Q235 kana simbi yakakandwa (yakadai seHT200).
Mapulley akaiswa pamitoro mikuru anowanzo ductile iron kana simbi yakakandwa (seZG270-500), inokandwa muchimiro chine mbariro nemaburi kana masipoki.
Mapulley mahombe (D> 800mm) anowanzo kuvezwa nezvikamu uye mahwendefa esimbi.
