Ngaphandle kwenkangeleko yazo ebonakala ingabalulekanga, izikrufu zizinto ezibalulekileyo koomatshini banamhlanje kunye nokwakhiwa. Uphawu lwazo olungundoqo lulele ekuqiniseni okusebenzayo, okubuyisela umva ngesakhiwo esinemisonto, ukudibanisa ukusebenza kunye nokuguquguquka.
Olona phawu lumangalisayo lwezikrufu kukuba isakhiwo simisela umsebenzi. Iintambo ze-helical zisebenza njengeerempu ezincinci, eziguqula amandla e-axial abe yi-lateral clamping force ngexesha lokujikeleza, iqinisekisa ukulingana okuqinileyo phakathi kwezinto ezidibeneyo. Olu luyilo lubavumela ukuba bamelane noxinzelelo, ukucheba, kunye netorque, nto leyo ebenza basetyenziswe ngokubanzi kwizicelo ukusuka kwizixhobo ezichanekileyo ukuya kwizixhobo ezinzima. Iiyantlukwano kwipitch yentambo (enjengemisonto erhabaxa yokudityaniswa ngokukhawuleza kunye nokuqhaqha, imisonto emihle yokutywina kunye nokuthintela ukukhulula) kunye neemilo zentloko (ezifana neentloko ezine-hexagonal ukuze kube lula ukusetyenziswa kwesixhobo kunye neentloko ezichaseneyo ukuze zivele kancinci) zandise ngakumbi izicelo zazo.
Iintlobo ngeentlobo zemathiriyeli kunye nonyango lomphezulu longeza ukuguquguquka kokusingqongileyo kwesikrufu. Izikrufu zentsimbi yekhabhoni zinokuvuswa okanye zenziwe mnyama ukunqanda umhlwa, ngelixa intsimbi engatyiwayo inokumelana nokufuma, okuneasidi, kunye nemekobume yealkaline. -Izikrufu ze-alloy eziphakamileyo zingasetyenziswa kwiinkqubo ezibango ezifana ne-aerospace. Ezinye izikrufu ezikhethekileyo zikwabonisa isakhono sobuqu- sokuzicofa (ukuvumela ukujija ngqo kwimathiriyeli ethambileyo ngaphandle-ukuzombiwa) okanye{6}}uyilo lokuzitshixa (ukuthintela ukukhulula ngeewasha ezilastiki okanye ukuguga kwentambo), ebonisa inguqulelo esebenzayo.
Imveliso esemgangathweni yezikrufu yenye inzuzo enkulu. Inkqubo yokucaciswa kwemetric/imperial emanyeneyo yehlabathi iqinisekisa ukuguquguquka, ivumela abasebenzisi ukuba badibanise ngokukhawuleza ubungakanani kunye namabakala amandla (umzekelo, ibakala 4.8 ukuya kwibakala 8.8), ukunciphisa kakhulu iindleko zolondolozo. Ukubuyiselwa umva kwabo "ukuqiniswa{6}}kunye{7}}nokuqhaqha" inqaku libonelela ngokulula kulungiso lwezixhobo kunye nokuphuculwa.
Nokuba isikrufu esinye sibonisa ubukrelekrele bobunjineli-ukukhulisa amandla amancinane ngolwakhiwo oluchubekileyo kunye nokulungelelanisa ukuguquguquka kunye nobuchule ngokumiswa emgangathweni. Obu buchule bokufikelela kwizinto ezinkulu ngomzamo omncinci ngundoqo kwisikhundla sabo esiqhubekayo njengesiseko semizi-mveliso kwiinkulungwane.
