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 yokuphepha.Ukwengeza, 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 enama-hexagonal high-strength, ukuze kwakhiwe kangcono.Ukwakhiwa kwamabhawodi anamandla aphezulu kumele 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 kumele kusetshenziswe isikrufu sikagesi sohlobo lwe-torsional shear, futhi ukuqiniswa kokugcina kohlobo lwe-torque amabhawodi anamandla aphezulu 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 ibhowodi 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 aqine kakhulu ohlobo lwe-Tensile: Imfuneko eyisisekelo yalolu hlobo lwamabhawodi anamandla 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 ekuxhunyweni kwekholomu yensimbi ezakhiweni zohlaka lwensimbi, uxhumo olusindayo lwemishayo ye-crane ezitshalweni zezimboni, uxhumo oluqinile lwe-web, amasistimu okubhuleka kanye nezakhiwo ezibalulekile ezithwala imithwalo enamandla.
(2) Ama-bolts anamandla amakhulu anamandla angasetshenziselwa ukuxhuma kwe-shear ezakhiweni zomthwalo we-static ezivumela inani elincane lokushelela 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 wamabhawodi). Ngakho-ke, afaneleka kuphela ukusetshenziswa ngaphansi kwe-static umthwalo, okufana ne-flange butt joint kanye ne-T-joint ye-compression bar.
