Ngowuphi uMahluko phakathi koKufota umsonto kunye nezikrweqe zokuCula imisonto?

Izikrufu zokucofa zenza imisonto yokukhwelana kwizinto eziqhutywa kuzo.Kukho iindidi ezimbini ezisisiseko: ukwenza intambo kunye nokusika intambo.

Isikrufu sokwenza intambo sishenxise imathiriyeli ejikeleze umngxuma wokulinga ukuze sijikeleze kwimisonto yesikrufu.Ezi zikrufu zisetyenziswa ngokubanzi xa uxinzelelo olukhulu lufuneka ukunyusa ukuxhathisa ukukhulula.Ngenxa yokuba akukho nto isusiweyo, inxalenye yokukhwelana idala ukulingana kunye nokukhutshwa kwe-zero.Ngokuqhelekileyo abafuni ii-lockwashers okanye ezinye iintlobo zezixhobo zokutshixa ukuthintela ukukhulula.

I-thread-tapping screws ine-cut edges kunye ne-chip cavities eyenza intambo yokukhwelana ngokususa izinto ezivela kwindawo eziqhutyelwa kuyo.Izikrufuâ??isenzo sokusika sithetha itorque efunekayo xa kufakwe iphantsi.Izikrufu zisetyenziselwa izinto apho uxinzelelo lwangaphakathi oluphazamisayo lungafunwa, okanye xa kuthatha i-torque yokuqhuba kakhulu ukusebenzisa i-thread-forming screws.

Ngokubanzi, izikrufu zokucofa zivumela ukufakwa ngokukhawuleza ngenxa yokuba amandongomane awasetyenziswanga kwaye ukufikelela kuyafuneka kwicala elinye kuphela lomdibaniso.Imisonto yokukhwelana eyenziwe ngezikrufu zokucofa ilingana ngokusondeleyo nemisonto ye-screw, kwaye akukho mvume ifunekayo.I-close fit ngokuqhelekileyo igcina izikrufu ziqinile naxa ziphantsi kwee-vibrations.

Izikrufu zokucofa zikholisa ukuba lukhuni kwaye zibe namandla okuqina angama-100,000 ubuncinci be-psi enamandla okugqibela aphezulu.Izikrufu zokucofa zisetyenziswa kwintsimbi, i-aluminiyam, i-die-castings, i-cast cast, i-forgings, iiplastiki, iiplastiki ezomeleziweyo kunye ne-resin-impregnated plywood.

Izikrufu zokucofa ziyafumaneka nokuba rhabaxa okanye ngemisonto ecolekileyo.Imisonto erhabaxa kufuneka isetyenziswe ngezinto ezibuthathaka.Imisonto emihle iyacetyiswa ukuba iindibano ezimbini okanye ngaphezulu ezipheleleyo zemisonto kufuneka zibe ngaphezulu kwendawo yokusika, kodwa imathiriyeli ayityebe ngokwaneleyo ukuvumela imisonto emibini egcweleyo yemisonto erhabaxa.
