Rail Screw Spike Fastening System
CovRailway Screw Spike(tseem hu ua cov ntsia hlau ntsia hlau lossis cov ntsia hlau pw tsaug zog) yog cov xov hlau uas tau tsim los ua kom muaj kev rub tawm zoo tshaj - tawm kev tiv thaiv rau kev ruaj ntseg rau cov ntoo pw tsaug zog lossis pw tsaug zog. Tsim los ntawm nruab nrab - carbon steel qib suav nrog 35 #, 45 #, 40Mn2, thiab 20MnSi, nrog cov chav kawm xws li 4.6 txog 8.8, cov spikes no ua tiav tensile zog ntawm 400-800 MPa nyob ntawm qib specification .

Installation & Maintenance Perspective:
- Siab -Tensile Variants:Premium ntsia hlau spikes ua tiav tensile lub zog ntawm 120,000 psi (Ntau dua lossis sib npaug ntawm 829 MPa) nrog lub zog tawm ntawm 92,000 psi (Ntau dua lossis sib npaug rau 635 MPa) thiab elongation Ntau dua lossis sib npaug li 14%, ua tau raws li ASTM A66 qhov yuav tsum tau ua rau txias dabtsi yog khoov 90 degree.
- Khoom siv:Cov pa roj carbon steel qib 35 # thiab 45 # muaj 0.32-0.50% carbon nrog manganese 0.50-0.80%, thaum alloyed qib zoo li 40Mn2 suav nrog 1.40-1.80% manganese rau kev txhim kho hardenability thiab lub zog.
- Pov thawj Load Test:Qib 8.8 spikes undergo pov thawj load pov thawj ntawm ntau dua los yog sib npaug rau 587 MPa, kom ntseeg tau tias elastic tus cwj pwm nyob rau hauv lub siab tshaj plaws tsim loads tsis tas yuav deformation.
Kev Saib Xyuas & Kev Pom Kev Ua Haujlwm
- Thread Engagement Principple:Cov xov helical (feem ntau yog M24 suab) faib rub- tawm lub zog raws tag nrho qhov ntev embedded, koom nrog lub ntim loj ntawm cov ntoo fibers piv rau kev sib txhuam-tsuas yog lub tshuab ntawm aub spikes .
- Rub-Tshem Tawm Qhov Zoo:Kev sim kuaj pom pom cov ntsia hlau spikes ua tiav 50-100% siab dua rub- tawm kev tawm tsam dua li qhov sib npaug ntawm tus dev spikes, txawm hais tias lateral (thrust) tsis kam yog kwv yees li 50% qis dua vim cov xov txoj kev taw qhia.
- Xov Profile Options:Muaj nyob rau hauv ntau yam xov configurations xws li txheem tshuab ntsia hlau threads, round threads (NF-F 50014), thiab tshwj xeeb profiles rau qhob sleeper inserts los yog yas dowels .
