Iibholiti zehexagon zediphu ezishushu zinokwenziwa ngokwezifiso
Ingcaciso yeMveliso
>>>
Kukho amagama amaninzi ahlukeneyo ebhonti yangaphandle enehexagonal, umzekelo, ingabizwa ngokuba yi-hexagonal bolt yangaphandle, umzekelo, ingabizwa ngokuba yi-hexagonal bolt yangaphandle. Isenokuthiwa ibholithi yangaphandle enehexagonal. Konke oku kuthetha into enye. Kuphela nje imikhwa yobuqu yahlukile. Emva konyango olushushu lwe-galvanizing surface, i-anti-corrosion effect ifunyenwe.
1. iibholiti eziqhelekileyo zohlulwe zibe ngu-a, b kunye no-c. Ezokuqala zimbini ziibholiti ezisulungekisiweyo, ezingafane zisetyenziswe. Ngokuqhelekileyo, iibholiti eziqhelekileyo zibhekisa kwiibholithi zeKlasi C eziqhelekileyo.
2. Iibholiti zeKlasi C eziqhelekileyo zisetyenziswa ngokuqhelekileyo kwezinye izixhumanisi zexeshana kunye nokudibanisa okudinga ukuchithwa. Iibholiti eziqhelekileyo ezisetyenziswa ngokuqhelekileyo kwizakhiwo zokwakha ziyi-M16, i-M20 kunye ne-M24. Ezinye iibholiti ezikrwada kwishishini lomatshini zinokuba needayamitha ezinkulu kunye neenjongo ezizodwa.
ibholithi yokubamba yamandla aphezulu
3. Izinto eziphathekayo ze-bolt zamandla aphezulu zihluke kwi-bolt eqhelekileyo. Iibholiti zamandla aphezulu zisetyenziswa ngokubanzi kunxibelelwano olusisigxina. Ngokuqhelekileyo zisetyenziswa yi-M16 ~ M30.
Ipleyiti yokuxhoma ehambelanayo isetyenziselwa ukudibanisa phakathi kwepleyiti enye kunye nepleyiti enye, naphakathi kwepleyiti enye kunye nepleyiti ephindwe kabini. Inokutshintsha kuphela ubude bendibano, kodwa hayi indlela yonxibelelwano. Ipleyiti yokuxhoma ehambelanayo ininzi yenziwe ngepleyiti yensimbi ngokunyathela kunye nenkqubo yokusika. Umgangatho wokusebenza webholiti yehexagon yangaphandle inamanani amabini, ngokulandelelanayo amele ixabiso lamandla okuqina kunye nomlinganiselo wamandla esivuno semathiriyeli yebholi.
Umzekelo, iibholithi ezinebakala lokusebenza 4.6 zithetha:
a. Izinto zeBolt: amandla okuzibamba afikelela kwi-400MPa;
b. Umlinganiselo wesivuno se-bolt material ngu-0.6;
c. Amandla emveliso yebholithi yegama ukuya kuthi ga kwi-400 × 0.6 = 240mpa ibakala
Iibholiti zamandla aphezulu kunye nebakala lokusebenza kwe-10.9 zinokuhlangabezana nezi mfuno zilandelayo emva konyango lobushushu:
a. Isixhobo se-Bolt, amandla okuzibamba ukuya kuthi ga kwi-1000MPa;
b. Amandla esivuno esiqhelekileyo semathiriyeli yebholi ukuya kuthi ga kwi-1000 × 0.9 = 900MPa ibakala
