Taug qab Bolt/Spittle Core Qib Xaiv thiab Xauv / Loosing Kev Tiv Thaiv Cov Cai
Dab tsi yog cov qhab nia tseem ceeb ntawm cov bolts thiab yoog raws cov xwm txheej?
Lub ntsiab bolts yog 8.8 qib thiab 10.9 qib siab - lub zog bolts, ntxiv rau cov ntses tshwj xeeb bolts, cov qhab nia raug muab faib raws li cov kab thauj khoom thiab kev ua haujlwm, thiab kev siv qis qis yog txwv tsis pub siv . 8.8 qib bolts yog cov qauv tseem ceeb rau txoj kev tsheb ciav hlau zoo tib yam thiab lub Hoobkas muaj zog ntau dua 8 MP los yog tensile zog. tshaj los yog sib npaug rau 640MPa, ua tau raws li qhov xav tau ntawm kev kaw haujlwm yooj yim nrog tus nqi pheej yig. 10.9 qib bolts yog tshwj xeeb rau kev siab - kev tsheb ciav hlau ceev thiab hnyav -cov dej num nrog tensile lub zog Ntau dua los yog sib npaug rau 1040MPa thiab tawm lub zog ntau dua los yog sib npaug rau 940MPa, tsis tshua muaj zog deloose thiab adaptation, {1 siab - zaus cuam tshuam rau kev ua haujlwm. Ntses bolts yog tshwj xeeb rau cov pob qij txha rail, haum rau ntses phaj xauv, specifications yog M24 / M27, xaiv raws li ntses phaj qauv, thiab tsis tuaj yeem siv universally nrog bolts zoo tib yam. Hnyav-lub luag haujlwm tiv thaiv- xoob siab- lub zog bolts nrog tiv thaiv- xoob xov yog siv rau kev lag luam thiab cov mining lem, tshwj xeeb rau hnyav-lub luag haujlwm hoisting scenarios, thiab tus qauv siab - lub zog bolts tuaj yeem siv rau cov xwm txheej zoo tib yam.
Dab tsi yog cov ntsiab lus tseem ceeb ntawm kauv spikes thiab yoog hom pw tsaug zog?
Kauv spikes yog cov khoom siv tseem ceeb rau cov neeg pw tsaug zog los txhim kho txoj hlua, lub teb chaws tus qauv tseem ceeb yog M24 sab sauv xov thiab M25.6 qis xov tshwj xeeb, haum rau kev teeb tsa tshwj xeeb ntawm cov pob zeb pw. Tag nrho qhov ntev ntawm kauv spikes Ntau dua lossis sib npaug li 200mm, cov xov qis qis yog cov hniav tshwj xeeb rau cov neeg pw tsaug zog ua ntej -embed, nrog lub zog kaw ntom nti tom qab screwing rau hauv lub sleeper thiab tsis yooj yim rau loosen thiab poob tawm. Cov txheej txheem txawv teb chaws kauv spikes yog nti xov, haum rau txawv teb chaws tus qauv pob zeb pw tsaug zog, European tus qauv siv M27 spikes, American standard siv nti 1-inch spikes, xaiv raws li qhov project qauv. Cov kev tsheb ciav hlau ib txwm siv cov txheej txheem kauv spikes, siab - txoj kev tsheb ciav hlau ceev siv cov hlua khi hlua khi kom tsis txhob taug kev luv luv Circuit Court, thiab txheej rwb thaiv tsev tuaj yeem siv tsuas yog tias tsis muaj kev puas tsuaj. Cov khoom siv ntsia hlau yog Q235-A steel, galvanized rau kev tiv thaiv corrosion ntawm qhov chaw, tsis sib xws hardness, tsis muaj xov slipping thiab tsis muaj pob txha thaum ntsia hlau, ua kom cov nyhuv kho ntawm cov pw tsaug zog thiab cov ntsia hlau.
Dab tsi yog qhov tseem ceeb ntawm kev ntsuas lub zog rau kev khiav bolt / ntsia hlau loj?
Lub ntsuas phoo ntawm cov ntsia hlau ntsia hlau yog nruj me ntsis raws li qib zog, 8.8 qib siab - lub zog bolts nrog torque 350-400N·m, 10.9 qib nrog 500-550N·m, sib txawv tsawg dua 5%. Lub xauv torque ntawm ntses bolts yog 380-420Nm, uas yuav tsum tau sib npaug zos rau plaub/rau bolts los xyuas kom meej lub zog sib npaug ntawm cov ntses phaj yam tsis muaj unilateral loosening. Spiral spike installation tsis tas yuav tsum muaj lub torque wrench, siv cov cuab yeej tshwj xeeb ntsia hlau, qhov tob tob tob dua los yog sib npaug ntawm 150mm, thiab cov ntsia hlau loj tuaj yeem siv tau yog tias tsis muaj kev co lossis xoob tom qab zawm. Lub torque sib txawv ntawm high-speed railway bolts xav tau kev tswj kom meej Tsawg dua los yog sib npaug rau ± 3%, zoo tib yam railway / kev lag luam thiab mining sib txawv tsawg dua los yog sib npaug rau ± 5%, ua tau raws li qhov tseeb ntawm cov kab sib txawv. Tsis txaus locking torque ua rau yooj yim loosening ntawm accessories; torque ntau dhau ua rau bolt slipping thiab tawg, ob qho tib si yuav tsum tau nruj me ntsis zam thiab tsim raws li cov qauv.
Dab tsi yog qhov tseem ceeb tiv thaiv -loosing ntsuas thiab tsim cov ntsiab lus ntawm cov bolts / spikes?
Cov tub ntxhais tiv thaiv -loosing ntsuas ntawm cov bolts yog "precise torque + structural anti-loosening + material anti-loosing", triple tiv thaiv kom tshem tawm loosening, uas yog qhov tseem ceeb txuas ntawm kev nyab xeeb kev nyab xeeb. Cov qauv kev tiv thaiv- loosening yog nruab nrog lub caij nplooj ntoos hlav ntxhua khaub ncaws thiab xauv cov txiv ntseej, lub elastic deformation ntawm lub caij nplooj ntoos hlav ntxhua khaub ncaws muab nruam ua ntej- zawm quab yuam, thiab xauv txiv ntseej tom cov xov kom tiv thaiv kev thim rov qab rau kev tiv thaiv ob npaug. Cov khoom siv los tiv thaiv- loosening siv siab- lub zog alloy steel bolts nrog xov precision qib 8g, tsis muaj xov slipping thiab tsis muaj burrs, nruj screwing kom tsis txhob loosening los ntawm xov khoob. Spike anti- loosening cia siab rau qhov tom ntawm cov xov tshwj xeeb qis thiab cov pw tsaug zog, xyuas kom cov xov huv si tsis muaj impurities thaum ntsia hlau, ntsia hlau mus rau qhov tob, thiab tshem tawm cov ntsia hlau virtual thiab raug tshem tawm. Ua kev soj ntsuam tsis tu ncua tom qab kev tsim kho, tshawb xyuas tus nqi torque thiab spike screwing lub xeev txhua hli, thiab tshuaj xyuas hnyav-cov dej num ua haujlwm txhua ib nrab ib hlis, rov kho dua thiab hloov cov khoom seem hauv lub sijhawm.
Dab tsi yog qhov teeb meem thiab kev saib xyuas ntawm bolts / spikes hauv kev siv?
Feem ntau cov teeb meem ntawm bolts / spikes yog xov slipping thiab puas, loosening thiab ntog tawm, xeb jamming, torque attenuation thiab xov puas, tag nrho cov yuav tsum tau kho tam sim ntawd kom tsis txhob khiav locking tsis ua hauj lwm. Bolt slipping thiab tawg yog vim lub zog ntau dhau los yog cov khoom siv tsis zoo, hloov siab - lub zog bolts ntawm tib qib, xauv raws li tus qauv torque, nruj me ntsis txwv tsis pub dhau - torque siv, thiab xyuas cov ntsia liaj qhov rooj zoo li ua ntej kev teeb tsa. Loosing thiab poob tawm yog vim tsis txaus torque los yog anti- loosening tsis ua hauj lwm, rov qab mus rau tus qauv torque, nruab anti-loosing accessories, thiab re-ntsia hlau ntsia hlau mus rau qhov tob yog xoob, ntxiv dag zog rau cov pw tsaug zog ua ntej - qhov chaw nyob. Kev xeb xeb yog vim los tiv thaiv- corrosion tsis ua hauj lwm, re-galvanize tom qab derusting, hloov ncaj qha yog xeb heev, thiab siv stainless hlau bolts nyob rau hauv ntub khiav seem nrog zoo anti{11}} xeb nyhuv. Torque attenuation yog vim ntev- siv lub sij hawm qaug zog, rov ua kom lub zog tsis tu ncua, teeb tsa lub zog saib xyuas cov cuab yeej rau hnyav-cov dej num los saib xyuas lub sijhawm. Xov puas yog tshwm sim los ntawm installation jamming, hloov bolts / spikes nrog zoo threads, huv si xov impurities ua ntej installation kom zoo screwing.
