Emkhiqizweni wethu wezimboni, amabhawodi avame ukuphuka, kungani-ke amabhawodi ephuka? Namuhla, ihlaziywa ikakhulukazi ezicini ezine.
Eqinisweni, amabhulothi amaningi aphuka ngenxa yokuxega, futhi aphuka ngenxa yokuxega. Ngenxa yokuthi isimo sokuxega nokuphuka kwebholithi sicishe sifane nesokuphuka kokukhathala, ekugcineni, singathola njalo isizathu samandla okukhathala. Eqinisweni, amandla okukhathala makhulu kangangokuthi asikwazi ukukucabanga, futhi amabhawodi awadingi amandla okukhathala nhlobo ngesikhathi sokusetshenziswa.
Okokuqala, ukuphuka kwebhawodi akubangelwa amandla aqinile ebhawodi:
Thatha ibholidi enamandla kakhulu engu-M20×80 yebanga lesi-8.8 njengesibonelo. Isisindo sayo singu-0.2kg kuphela, kuyilapho ubukhulu bayo be-tensile bungama-20t, obuphakeme ngokuphindwe ka-100,000 isisindo sawo. Ngokuvamile, siyisebenzisa kuphela ukubopha izingxenye ezingu-20kg futhi sisebenzisa ingxenye eyodwa kuphela yenkulungwane yomthamo wayo omkhulu. Ngisho nangaphansi kwesenzo samanye amandla emishini, akunakwenzeka ukugqashuka izikhathi eziyinkulungwane zesisindo sezingxenye, ngakho-ke amandla aqinile we-fastener ene-threaded anele, futhi akunakwenzeka ukuthi ibhawodi lonakaliswe ngenxa amandla anganele.
Okwesibili, ukuphuka kwebhawodi akubangelwa amandla okukhathala kwebhawodi:
Isixhumi singathukululwa izikhathi eziyikhulu kuphela esivivinyweni sokukhulula ukudlidliza okuphambene, kodwa sidinga ukudlidliza izikhathi eziyisigidi ngokuphindaphindiwe esivivinyweni samandla wokukhathala. Ngamanye amazwi, i-fastener enentambo iyaxega uma isebenzisa ingxenye eyizinkulungwane eziyishumi zamandla ayo okukhathala, futhi sisebenzisa ingxenye eyodwa kuphela yezinkulungwane eziyishumi zomthamo waso omkhulu, ngakho-ke ukuxegiswa kwe-fastener enentambo akubangelwa amandla okukhathala kwebhawodi.
Okwesithathu, isizathu sangempela somonakalo wezinsimbi ezinentambo ukuxega:
Ngemuva kokuthi isibambiso sesikhululiwe, kukhiqizwa amandla amakhulu e-kinetic mv2, asebenza ngqo kusixhumi nemishini, okwenza ukuthi isibambiso sonakaliswe. Ngemva kokulimala kwe-fastener, okokusebenza akukwazi ukusebenza esimweni esivamile, okuholela ekulimaleni kwemishini.
Intambo yesikulufu se-fastener engaphansi kwamandla e-axial iyabhujiswa futhi ibhawudi liyakhishwa.
Ezibopheni ezingaphansi kwamandla e-radial, ibhawodi liyagundwa futhi imbobo yebhawodi i-oval.
Okwesine, khetha indlela yokuvala intambo enomphumela omuhle kakhulu wokukhiya kuyisisekelo sokuxazulula inkinga:
Thatha isando se-hydraulic njengesibonelo. Isisindo sesando se-hydraulic GT80 singamathani angu-1.663, kanti amabhawodi ayo aseceleni angamasethi angu-7 wamabhawodi angu-M42 ekilasi 10.9. Amandla aqinile ebhawodi ngalinye angamathani ayi-110, futhi amandla okuqinisa abalwa njengengxenye yamandla aqinile, futhi amandla okuqina afinyelela amathani angamakhulu amathathu noma amane. Nokho, ibholidi izophuka, futhi manje isilungele ukushintshwa ibe yibhawodi engu-M48. Isizathu esibalulekile ukuthi ukukhiya ibhawudi akukwazi ukukuxazulula.
Lapho ibhawodi liphuka, abantu bangaphetha kalula ngokuthi amandla ayo awanele, ngakho-ke iningi labo lithatha indlela yokwandisa izinga lamandla lobubanzi bebhawodi. Le ndlela ingakhuphula amandla okuqinisa amabhawodi ngaphambili, futhi amandla ayo okungqubuzana nawo anyusiwe. Vele, umphumela wokulwa nokuxega ungathuthukiswa. Nokho, le ndlela empeleni iyindlela engeyona eyochwepheshe, enotshalomali oluningi kanye nenzuzo encane kakhulu.
Ngamafuphi, ibhawodi lithi: “Uma ungalixegi, lizophuka.”
