Hlau Shed Screws

Lub taub hau tsav qauv ntawm Hlau Shed Screws tau ua kom zoo thiab tsim. Qhov siab thiab rov qab-sab nrug ntawm nws lub taub hau hexagonal flange yog raws li ISO 898-1 qhov yuav tsum tau ua siab ntev rau fastener geometric qhov ntev. Raws li ST5.5 specification, qhov sib txawv ntawm qhov sib txawv - sab nrug yog tswj nyob rau hauv ntxiv los yog rho tawm 0.2 hli, ua kom ruaj khov haum nrog tus qauv socket ciaj ntswj thiab tsis txhob ntog los ntawm kev tshem tawm ntau dhau. Lub caj dab ntawm cov ntsia hlau yog nruab nrog ib qho annular stress nyem zawj. Qhov kev tsim no tso cai rau lub torsional stress concentration point generated thaum lub sij hawm zawm txheej txheem yuav kis tau los ntawm cov xov hauv paus mus rau lub caj dab. Raws li txoj kev sim rau torsional lub zog ntawm fasteners nyob rau hauv Part 26 ntawm DIN 267, qhov tawg torque ntawm screws nrog kev ntxhov siab grooves yog kwv yees li 15% siab tshaj qhov uas tsis yog -grooved lug. Raws li M6 specification, qhov ntsuas tawg torque ncav cuag 8.5 Nm, thiab qhov kev nyab xeeb yog nce mus rau 2.2 npaug. Tom qab kev teeb tsa, qhov haum ntawm ntug qis ntawm lub taub hau taub hau flange thiab qhov chaw ntawm lub phaj ncaj qha cuam tshuam rau kev tiv thaiv -loosing kev ua tau zoo ntawm kev sib txuas. Raws li txoj kev ntsuas kev vibration tom qab, tom qab 25,000 lub voj voog ntawm qhov zaus ntawm 20 Hz thiab qhov amplitude ntawm 2.5 hli, qhov seem seem pre-tightening quab yuam tuav tus nqi ntawm cov ntsia hlau nrog kev ntxhov siab groove tsim tseem nce mus txog 86% ntawm tus nqi pib, uas yog li ntawm 10 feem pua ​​​​ntawm cov qauv.

 

 

Nyob rau hauv ib puag ncig ntawm alternating kub, qhov sib txawv ntawm thermal expansion tus cwj pwm ntawm cov hlau shed screws thiab cov sib txuas daim hlau cuam tshuam lub preload stability. Raws li ASTM E228 thermal expansion coefficient ntsuas txoj kev, cov kab nthuav dav coefficient ntawm carbon steel screws yog kwv yees li 11.7 microns ib meter ib Kelvin, thaum qhov sib txuam galvanized steel phaj yog li 12.2 microns ib meter ib Kelvin. Qhov sib txawv ntawm ob yog thaum lub ambient kub nce los ntawm rho tawm kaum degrees Celsius mus rau plaub caug degrees Celsius. Rau cov ntsia hlau nrog qhov ntev ntawm 30 millimeters, qhov sib txawv thermal elongation ntawm nws thiab phaj yog li 4.5 microns. Qhov sib txawv me me no tuaj yeem raug them los ntawm elastic elongation ntawm cov ntsia hlau nws tus kheej, thiab tsis tas yuav txhawj xeeb txog qhov tseem ceeb ntawm lub zog ua ntej. Thaum siv nyob rau hauv cov ntug dej hiav txwv siab- thaj chaw av noo, tiv thaiv -corrosion system ntawm cov ntsia hlau yuav tsum suav nrog zinc{12}} aluminium composite txheej. Raws li ISO 9227 tooj liab nrawm acetic ntsev tsuag tshuaj ntsuam, txheej txheej tsis muaj xeb dawb ntawm qhov chaw thiab tsis muaj xeb liab ntawm lub matrix tom qab yim puas teev ntawm raug. Nyob rau tib lub sijhawm, hauv kev ntsuas thermal poob siab los ntawm -20 degrees Celsius mus rau 60 degrees Celsius, txheej adhesion tseem tuav qib 4B raws li ASTM D3359 tus ntoo khaub lig-hatch txoj kev tom qab ib puas ua tiav, qhia tias nws muaj thermal stress peeling kuj zoo heev. Lub ntsis laum ntug ntawm cov ntsia hlau tseem tuaj yeem tuav lub peev xwm rov qab siv tsawg kawg tsib zaug tom qab nkag mus rau ob - txheej hlau phaj. Nws tau ntsuas tias tom qab tsib tus ntsia hlau ntawm tib lub ntsiab lus txuas ntxiv nkag mus rau 2.0 hli tuab galvanized phaj, lub sijhawm drilling tsuas yog nce los ntawm thawj 3.2 vib nas this mus rau 3.8 vib nas this. Qhov kev ua tau zoo degradation tau tswj tsis pub dhau 20%, uas ua tau raws li qhov xav tau tiag tiag los hloov cov ntsia hlau vim kev ua haujlwm tsis raug thaum lub sijhawm tsim kho.
