Qib 10.9 Torque-Shear Bolts
Cov Txheej Txheem Tseem Ceeb
**Cov Lus Qhia Tshwj Xeeb thiab Cov Khoom Siv:** Cov lus qhia tshwj xeeb feem ntau yog txij li M16 txog M30, nrog rau qhov ntev feem ntau yog txij li 40mm txog 220mm. Cov ntaub ntawv siv suav nrog cov hlau sib xyaw xws li 20MnTiB thiab 35VB. Cov lus qhia tshwj xeeb ntawm M16-M24 feem ntau siv 20MnTiB, thaum cov lus qhia tshwj xeeb ntawm M27-M30 feem ntau siv 35VB. Cov ntaub ntawv no muab lub hauv paus rau kev ua haujlwm siab ntawm cov bolts.
**Cov Qauv:** Yuav tsum ua raws li GB/T3632-2008 tus qauv. Lub taub hau ntsia hlau yuav raug cim nrog qib kev ua tau zoo ntawm 10.9S, qhov twg "S" sawv cev rau lub ntsia hlau muaj zog siab rau cov qauv hlau, ua rau yooj yim txheeb xyuas thiab taug qab zoo.
Cov Khoom Siv Sib Txuas: Txhua khub sib txuas muaj ib lub ntsia hlau, ib lub txiv ntoo muaj zog 10H, thiab ib lub washer muaj zog HRC35-45. Tag nrho peb yam khoom yuav tsum tau tsim ua ke hauv tib pawg kom tsis txhob muaj kev hloov pauv ntau yam uas cuam tshuam rau kev ruaj khov ntawm kev sib txuas.
Cov Cim Qhia Txog Kev Ua Tau Zoo Tseem Ceeb
Cov Khoom Siv Kho Tshuab Zoo Kawg Nkaus: Ua ib lub ntsia hlau muaj zog siab, nws lub zog tensile yog nruab nrab ntawm 1040-1240 MPa, nws lub zog tso tawm tsis tsawg dua 940 MPa, nws qhov elongation tsis tsawg dua 10%, thiab nws qhov shrinkage ncav cuag 42%. Nws tuaj yeem yooj yim tiv taus cov khoom thauj dynamic thiab cov khoom thauj preload siab, ua rau muaj kev tiv thaiv kev qaug zog, thiab tuaj yeem txo qhov kev ntxhov siab hauv qab cov khoom thauj dynamic, ua rau lub neej ua haujlwm ntawm cov qauv hlau ntev dua.
Kev Tiv Thaiv Kev Xeb Yooj Yim: Muaj ntau yam kev kho saum npoo av. Rau cov chaw ib txwm muaj, kev ua kom dub thiab phosphating yog cov kev xaiv, tsim cov zaj duab xis tiv thaiv uas sib npaug kev tiv thaiv xeb thiab kev sib txhuam coefficient ruaj khov. Rau cov chaw tshwj xeeb xws li cov platforms marine thiab cov chaw muaj ntsev ntau, Dacromet txheej lossis hot-dip galvanizing tuaj yeem siv tau. Dacromet txheej, ua ib txheej zinc-aluminium uas zoo rau ib puag ncig, qhia txog kev tiv thaiv xeb zoo heev.
Cov Kev Zoo ntawm Kev Tsim Kho thiab Kev Tsim Kho
Kev Tsim Qauv Tshwj Xeeb: Lub taub hau ntsia hlau yog cov duab nceb nrog lub hau zoo li sprite nyob rau thaum kawg. Lub hau zoo li sprite no yog qhov tseem ceeb ntawm kev tsim kho thiab kev tshuaj xyuas zoo. Hauv qab ntawm lub taub hau tau kho nrog cov txheej tiv thaiv kev plam kom tiv thaiv lub ntsia hlau kom tsis txhob plam lossis tig thaum lub sijhawm teeb tsa, txo cov teeb meem kev nyab xeeb uas tshwm sim los ntawm kev teeb tsa tsis raug.
Kev Teeb Tsa Yooj Yim thiab Zoo: Kev teeb tsa siv lub wrench torque tshwj xeeb. Lub tes tsho sab nraud tau teeb tsa rau ntawm lub txiv ntoo, thiab lub tes tsho sab hauv tau teeb tsa nrog lub taub hau zoo li sprite. Kev nruj yog ua tiav los ntawm kev tawm tsam. Thaum lub zog torque mus txog tus nqi txheem, lub taub hau zoo li sprite yuav tawg cia, qhia tias qhov preload tau mus txog 95-105% ntawm tus nqi tsim. Qhov no tshem tawm qhov xav tau kev ntsuas lub zog tes thiab zam kev ua yuam kev los ntawm kev hloov pauv ntawm cov coefficient sib txhuam hauv cov txheej txheem torque ib txwm muaj, ua rau qhov zoo ntawm kev tsim kho yooj yim thiab tswj tau.
Cov Cheeb Tsam Tseem Ceeb
Cov ntsia hlau no yog ib qho tseem ceeb ntawm kev sib txuas ntawm cov qauv hlau thiab muaj ntau yam kev siv. Hauv kev tsim kho, nws tsim nyog rau cov kav dej tseem ceeb ntawm cov tsev siab, cov trusses ntawm cov chaw ua si loj, cov pob qij txha ntawm cov chaw tsim khoom, thiab lwm yam; hauv kev tsim choj, nws tuaj yeem siv rau kev sib txuas ntawm cov nqaj hlau loj, kev sib txuas ntawm lub lawj choj thiab cov pob qij txha ntawm lub tsev dai ...
