Cov khau khiav yog ib qho ntawm undercarriage ib feem ntawm kev tsim kho machinery thiab ib feem tsis zoo ntawm kev tsim kho tshuab siv.Nws yog commonly siv nyob rau hauv kev tsim kho machinery xws li excavators, bulldozers, crawler cranes, thiab pavers.
Tus qauv ntawmtaug nkawm khau
Feem ntau cov khau taug qab tau muab faib ua peb hom raws li cov duab hauv av, ib leeg-rib, peb-rib thiab flat-bottomed, thiab qee qhov ntawm lawv siv cov khau khiab triangular.Cov khau khiab ib leeg yog siv rau cov tsheb bulldozers thiab tsheb laij teb, vim tias cov tshuab no xav tau cov khau taug qab kom muaj peev xwm traction siab.Txawm li cas los xij, nws tsis tshua siv rau ntawm excavators.Hom kev taug qab khau no tsuas yog siv thaum lub excavator yog nruab nrog lub laum thav duab lossis xav tau ib txoj kab rov tav loj.Yuav tsum muaj zog traction ntau dua thaum tig, yog li cov tread bars ntau dua (piv txwv li, spurs) yuav nyem tawm cov av (lossis hauv av) ntawm cov tread tuav, yog li cuam tshuam rau kev ua haujlwm ntawm excavator.
Cov khau khiab hlau tuaj yeem muab faib ua: daim hlau excavator thiab daim hlau bulldozer, ob qho no feem ntau yog siv, nrog rau seem hlau ua raw khoom.Tom qab ntawd muaj cov av ntub dej siv los ntawm cov bulldozers, feem ntau hu ua "daim duab peb sab", uas yog lub phaj cam khwb cia.Lwm hom cam khwb cia yog siv rau crawler cranes.Qhov hnyav ntawm lub phaj no yog los ntawm kaum ntawm kilograms mus rau pua pua kilograms.
Hloov steel rautaug nkawm khau
Cov khau ntawm cov tsheb taug qab feem ntau yog ua los ntawm cov hlau manganese siab nrog keeb kwm ze li 100 xyoo.Qhov no yog vim hais tias siab manganese hlau muaj ib tug tseem ceeb feature, uas yog, nws undergoes cuam tshuam hardening nyob rau hauv qhov kev txiav txim ntawm tej load, thiaj li hais tias nws tsim ib tug nyuaj thiab hnav-resistant nto txheej, thaum tseem tuav lub toughness thiab plasticity ntawm nws puab qauv.Txawm li cas los xij, cov hlau manganese siab yog siv los ua cov khau khiav, thiab nws feem ntau puas thaum ntxov vim tawg, cov hniav rov qab thiab deflection thaum siv, thiab nws lub neej kev pab cuam tsawg.Txhawm rau kov yeej qhov tsis txaus ntseeg no, cov hlau tsis tshua muaj zog siab 30SiMnMoV (Ti) steel raws li cov peev txheej hauv tsev thiab tsim tau yooj yim.Nws tau ua tiav siv los hloov cov hlau manganese siab los tsim cov khau khiav.
Txoj kev ua
Cov txheej txheem txheej txheem ntawm cov khau profile yog feem ntau: siv qhov profile blanking, drilling (punching), kho cua sov, straightening, painting thiab lwm yam txheej txheem;txoj kev khiav ntawm lub bulldozer yog ib qho kev txhawb zog, thiab cov xim xim dav dav yog daj;lub phaj excavator feem ntau Nws yog peb tav, thiab cov xim xim yog xim dub.Cov khoom siv profile feem ntau yuav yog 25MnB, thiab qhov kawg kev kho cua sov hardness ntawm cov khoom yog HB364 ~ 444.
