Imininingwane Yamandla Aphezulu Amabhawodi
Ngokwesimo sokucindezeleka, ingahlukaniswa ngohlobo lokungqubuzana nohlobo lwengcindezi: Empeleni, kunomehluko kumklamo kanye nezindlela zokubala.Uhlobo lwe-friction amabhawodi anamandla aphezulu athatha ukushelela phakathi kwamapuleti njengesimo somkhawulo womthamo wokuthwala.Amabhawodi ohlobo lwe-I aphezulu athatha ukushelela phakathi kwama-slabs njengesimo somkhawulo esivamile, kanye nokwehluleka kokuxhumeka njengesimo somkhawulo somthamo wokuthwala.Amabhawodi anamandla amakhulu efriction awakwazi ukunikeza ukudlala okugcwele kumandla wamabhawodi.Ekusetshenzisweni okungokoqobo, amabhawodi ohlobo lokungqubuzana kufanele asetshenziselwe izakhiwo ezibaluleke kakhulu noma izakhiwo ezithwele imithwalo eguquguqukayo, ikakhulukazi uma imithwalo ibangela ukuhlehla kwengcindezi.Ngalesi sikhathi, amandla ebhawodi angasetshenzisiwe angasetshenziswa njengendawo yokugcina ukuphepha.Ngaphezu kwalokho, ama-bolts anamandla aphezulu kufanele asetshenziselwe ukunciphisa izindleko.
Ngokobuchwepheshe bokwakha, ihlukaniswe yaba: uhlobo lwe-torsional shear high-strength bolt kanye nebhawodi enkulu enehexagonal high-strength bolt.Ibhawodi enama-hexagonal high-strength grade ingeyebanga lamandla aphezulu ezikulufu ezijwayelekile, kanti uhlobo lwe-shear high-strength bolt iwuhlobo oluthuthukisiwe lwebhawodi lamandla aphezulu anama-hexagonal, ukuze kwakhiwe kangcono.Ukwakhiwa kwamabhawodi anamandla aphezulu kufanele kuklwelwe kuqala bese kuthi ekugcineni, futhi uhlobo lomthelela we-wrench kagesi noma isikrufu sikagesi esilungiseka nge-torque kufanele sisetshenziselwe ukukrufulwa kokuqala kwamabhawodi anamandla amakhulu;Kodwa-ke, kunezidingo eziqinile zokuqiniswa kokugcina kwama-bolts aphezulu.Ukuqiniswa kokugcina kwamabhawodi ohlobo lwe-torsional shear aqine kakhulu kufanele kusetshenziswe isikrufu sikagesi sohlobo lwe-torsional shear, futhi ukuqinisa kokugcina kohlobo lwe-torque enamandla amakhulu amabhawodi kufanele kusebenzise isikrufu sikagesi sohlobo lwe-torque.Ibhawodi eliyi-hexagonal liqukethe ibhawodi, inati namawasha amabili.Ibhawodi yamandla aphezulu yohlobo lwe-shear iqukethe ibhawodi, inati kanye newasha.
1. Ibhawodi elinamandla amakhulu elithwala umfutho: Lolu hlobo lwebhawodi lamandla amakhulu lusetshenziswa ikakhulukazi ekuxhumaneni phakathi kwezingxenye zesakhiwo ezimile noma ezishelela kancane.Kudingeka ukuthi i-bolt yamandla aphezulu isetshenziselwe umthamo oqinile wokuthwala ingcindezi kanye nokumelana okuqinile kwe-shear.
2. Ibhawodi yamandla aphezulu yohlobo lwe-Friction: Lolu hlobo lwebhawodi lamandla amakhulu lusetshenziswa ngokuyinhloko ukuxhumana phakathi kwesistimu yokubhuleka kanye nezakhiwo ezibalulekile ezithwele imithwalo eguquguqukayo, njengokuxhunywa kwemishayo ye-crane esindayo kanye nemishayo yewebhu eqinile.
3. Amabhawodi aqinile ohlobo lwe-Tensile: Imfuneko eyisisekelo yalolu hlobo lwamabhawodi aqine kakhulu ukuthi amabhawodi akulula ukuwohloka, ukuphuka noma ukuwa ngaphansi kwengcindezi eqinile, njll. Avame ukusetshenziselwa ukuxhumana kwe-flange yokucindezela. izingxenye.
Ama-bolts anamandla aphezulu afaneleka ezindlini ezinkulu ze-span, izakhiwo zensimbi zezitshalo zezimboni, izakhiwo zensimbi zensimbi zezakhiwo eziphakeme, izakhiwo zebhuloho, imishini yokuphakamisa okunzima nezinye izakhiwo ezibalulekile.
Ngokusho kohlobo lokuxhumana, kunezinhlobo ezintathu ezilandelayo:
(1) Amabhawodi anamandla amakhulu okufakwa nokwesula afaneleka ekuxhumekeni kwekholomu yensimbi ezakhiweni zohlaka lwensimbi, uxhumo olusindayo lwemishayo ye-crane ezitshalweni zezimboni, uxhumo oluqinile lwebhuloho yewebhu, amasistimu okubhuleka kanye nezakhiwo ezibalulekile ezithwala imithwalo enamandla.
(2) Ama-bolts anamandla aphezulu angasetshenziselwa ukuxhuma kwe-shear ezakhiweni zomthwalo we-static ezivumela inani elincane lokuslayida noma ezingxenyeni ezithwala ngokungaqondile imithwalo eguquguqukayo.
(3) Amabhawodi aqinile aqinile anamandla aphansi okukhathala ekucindezelekeni, futhi amandla awo okuthwala angeke adlule kalula ku-0.6P(P ngaphansi komthwalo oguquguqukayo (P ingamandla e-axial avumelekile amabhawodi). Ngakho-ke, afaneleka kuphela ukusetshenziswa ngaphansi kwe-static umthwalo, njenge-flange butt joint kanye ne-T-joint ye-compression bar.
