I-screw yindibaniselwano yoomatshini abalula: ngokwenene, yinqwelomoya etyekeleyo ejikelezwe kwishafti esembindini, kodwa inqwelo-moya ethe tye (umsonto) nayo ifika kumphetho obukhali ojikeleze ngaphandle, osebenza njenge wedge njengoko ityhala ngaphakathi. izinto eziqiniweyo, kunye ne-shaft kunye ne-helix nayo yenza i-wedge kwinqanaba.Eminye imisonto yezikrufu iyilelwe ukuba idibane nomsonto oncedisanayo, obizwa ngokuba ngumsonto obhinqileyo (umsonto wangaphakathi), ngokufuthi ukwimo yento ye-nut enomsonto wangaphakathi.Eminye imisonto ye-screw iyilelwe ukusika i-helical groove kwinto ethambileyo njengoko isikrufu sifakwa.Olona setyenziso luxhaphakileyo lwezikrufu kukubamba izinto kunye nokubeka izinto.
Isikrufu siya kuba nentloko kwelinye icala elivumela ukuba lijikwe ngesixhobo.Izixhobo eziqhelekileyo zokuqhuba izikrufu ziquka i-screwdrivers kunye ne-wrenches.Intloko idla ngokuba nkulu kunomzimba wesikrufu, ogcina isikrufu singaqhutywa nzulu kunobude besikrufu kunye nokubonelela ngomphezulu wokuthwala.Kukho iinketho.Ibholithi yekhareji inentloko elawulayo engenziwanga ukuba iqhutywe.I-screw iseti ingaba nentloko elinganayo okanye encinci kunobubanzi obungaphandle be-screws thread;isikrufu esisetiyo esingenantloko ngamanye amaxesha sibizwa ngokuba sisikruru segrub.Ibholithi engu-J inentloko emile okwe-J etshoniswa kwikhonkrithi ukuze isebenze njengebholithi yeankile.
Inxalenye ye-cylindrical ye-screw ukusuka ngaphantsi kwentloko ukuya kwincam ibizwa ngokuba yi-shank;isenokusongelwa ngokuzeleyo okanye ngokuyinxenye.[1]Umgama phakathi komsonto ngamnye ubizwa ngokuba yipitch.[2]
Uninzi lwezikrufu kunye neebholiti ziqiniswa ngokujikeleziswa kwewotshi, ebizwa ngokuba ngumsonto wasekunene.[3][4]Izikrufu ezinomsonto ongasekhohlo zisetyenziswa kwiimeko ezizodwa, njengendawo apho isikrufu siya kuxhomekeka kwitorque echasene newotshi, ethanda ukukhulula isikrufu sasekunene.Ngesi sizathu, i-pedal yecala lasekhohlo yebhayisekile inomsonto ongasekhohlo.
