Ngaba kufuneka ndiqinise iBolt okanye iNut kuQhagamshelo lweBolt-Nut?

Kudibaniso oluphothiweyo, ndingakhetha njani phakathi kokuqinisa indongomane kunye nokuqinisa ibholithi?

Kuxhulumaniso oludibeneyo, umbuzo wokuba ukuqinisa i-nut okanye ukuqinisa i-bolt akufuneki ukuba kuthathelwe ingqalelo kwi-rivets e-riveted, i-rivet nuts, i-welded nuts, i-bolts edibeneyo, njl.

Ingaba ukuqinisa ibholithi okanye i-nut idla ngokuqwalaselwa kwikhonkco le-bolt-nut. Kwiimeko ezininzi zokusebenza, xa kungekho zidingo ezikhethekileyo, i-nut igxininiswe ngokukodwa ukuqinisa uxhumano. Nangona kunjalo, kwiimeko ezikhethekileyo apho indawo yokusebenza ilinganiselwe kwaye isixhobo sokuqinisa asikwazi ukusetyenziswa, i-nut iya kunyanzeliswa kuqala, kwaye i-bolt iya kuqiniswa ukufezekisa uxhulumaniso oluqiniweyo.

Uthini umahluko phakathi kokuqinisa indongomane kunye nokuqinisa ibholithi?

Umahluko omkhulu phakathi kokuqinisa i-bolt kunye nokuqinisa i-nut kukuba i-coefficient ye-friction iyahluka, eya kukhokelela kumahluko kwi-preload force ye-bolt phantsi kwe-torque efanayo. Ukuba amandla okulayisha kwangaphambili kufuneka alawulwe ngokungqongqo, kuya kubakho umahluko phakathi kwezi zimbini. Nangona kunjalo, xa i-coefficient ye-friction kunye ne-support surface diameter ifana, uxinzelelo lwe-tensile kunye ne-torsional shear stress of tightening bolt kunye ne-nut ziyafana, kwaye kulungile ukuqinisa nayiphi na enye. Ngokwembono yesiqhelo, abantu bajija amantongomane rhoqo.

Akukho mgangatho ufanelekileyo othi iibholithi okanye iinati mazijijwe. Ngokumalunga nezixhobo zokunyanzelisa, i-socket wrench emfutshane ingasetyenziselwa ukujiya iibholithi. Xa u-screwing nuts, ubude obuvezwayo beebholiti kufuneka buqwalaselwe. I-wrench ye-socket esetyenziswa ngokubanzi ixesha elide, elinokunyusa ezinye iindleko. Nangona kunjalo, kwiinkqubo ezininzi zokulwa nezixhobo zokujikeleza, i-wrenches emide ye-socket nayo isetyenziselwa ukukrazula iibholithi, ngoko ke kulo mba, iibholiti ze-screwing kunye ne-screw nuts azifani kakhulu.

Isizathu sokuba abantu baqhele ukujija amantongomane ngakumbi kukuba ukuba iibholiti azilungelelaniswanga, kuya kubakho ukungqubana phakathi kwe-screw kunye nomngxuma owenziwe ngaphambili, ngaloo ndlela benyusa i-torque ye-friction kunye nokwandisa i-torque yokufaka, ngelixa i-screw nuts ayinayo le ngxaki.

Ngamafutshane, iibholithi zokujija kunye namantongomane ziyafana kwiimeko ezininzi. Ukusuka kwimbono yokulula, amantongomane acinywa kakhulu. Ngaphandle kokuba akukho lula ukujija amandongomane phantsi kweemeko ezikhethekileyo zokusebenza, khetha ke ukujija iibholithi. Ewe kunjalo, kungcono ukucacisa xa uyila ukuba ujije amantongomane okanye iibholiti ukuze ufezekise iimfuno zoyilo lwangaphambili.
