Rail Screw Spike Fastening System
Lub Rail Screw Spike yog qhov tseeb -engineered, threaded fastener txawv los ntawm nws qhov sib sib zog nqus helical xov daim ntawv thiab forged lub taub hau profile, tsim los kom ruaj ntseg rau cov ntoo pw tsaug zog los yog cov pob zeb ua vaj tse nrog ua ntej - ntsia inserts los ntawm kev sib hloov installation es tsis muaj kev cuam tshuam rau kev tsav tsheb. Tsis zoo li cov kab pheeb ces kaum -Action aub spike uas tso siab rau cov ntoo fiber ntau compression, cov ntsia hlau ntsia hlau tsim muaj lub zog los ntawm cov khoom siv zoo sib xws- nws cov xov koom nrog cov khoom siv pw tsaug zog lossis ntxig los tsim kom tshem tau, siab - lub zog sib txuas uas xa tawm rub- tawm tsam kwv yees li 2.5 npaug ntau dua li tus dev sib npaug.
Technical Specifications:
| Parameter | Ntsia Hlau Spike | Dog Spike | Lag Ntsia Hlau | Elastic Rail Clip |
|---|---|---|---|---|
| Txoj Cai Fastening | Threaded mechanical interlock | Fiber compression (kev sib txhuam) | Threaded kev koom tes | Calibrated caij nplooj ntoos hlav quab yuam |
| Sleeper Compatibility | Ntoo los yog pob zeb (nrog ntxig) | Ntoo nkaus xwb | Ntoo nkaus xwb | Qhob, steel, composite |
| Txoj Kev Txhim Kho | Rotational (torque{0}}tswj) | Kev cuam tshuam tsav tsheb | Rotational (yeem) | Nias -in los yog clip driver |
| Rub -Tshem Tawm | Siab heev (2,500-5,000 lb) | Nruab nrab (2,000-4,000 lb) | Siab | N/A (clamping quab yuam) |
| Thrust Resistance | Nruab nrab | Zoo (pab pawg ua haujlwm) | Nruab nrab | Siab |
| Installation Ceev | Nruab nrab (threaded) | Ceev heev (kev cuam tshuam) | Slow (manual) | Ceev ceev |
| Kev tshem tawm nyuaj | Tsawg (rov qab tig) | Nruab nrab (yuav tsum rub) | Tsawg | Tsawg |
Installation & Maintenance Perspective:
- Asymmetric Xov Profile:Lub siab flank (load-cov kabmob nto) yog taw qhia ntawm 90-100℃mus rau qhov sib npaug axis, optimizing tsis kam mus rau ntsug uplift thaum lub clearance flank lub kaum sab xis pab txhim kho thiab tshem tawm.
- Xov Pitch Optimization:Standard pitches ntawm 6-12 hli sib npaug installation ceev tiv thaiv tuav lub hwj chim-coarser threads nruab sai dua tab sis muab kev koom tes hauv cheeb tsam tsawg dua li cov xov sib txawv.
- Rub-Out vs. Thrust yam ntxwv:Thaum rub- tawm kev tawm tsam tshaj li dev spikes los ntawm 150%, lateral thrust resistance ntsuas kwv yees li 40-50% qis dua, yuav tsum tau nyob ze dua spike spacing los yog ntxiv fastening nyob rau hauv siab load daim ntaub ntawv.
Kev Saib Xyuas & Kev Pom Kev Ua Haujlwm
- Quenched thiab Tempered Structure:Hwm spikes tau dhau los ntawm - hardening ua raws li tempering ntawm 400-500 degree, ua tiav core hardness ntawm 25-35 HRC uas sib npaug hnav tsis kam nrog toughness los tiv thaiv kev cuam tshuam thaum lub sij hawm installation.
- Case Hardening Options:Rau ib puag ncig nruj, induction rooj tawv tawv tsim ib qho hnav- cov txheej txheej tiv taus (45-55 HRC) mus rau 2-3 hli qhov tob thaum tuav cov khoom siv ductile.
- Ci Hardening Effect:Kev tswj kom txias tom qab forging txhawb nqa nag lossis daus hardening uas ua rau kom muaj zog tawm los ntawm 15-20% yam tsis muaj cov ntsiab lus alloying ntxiv.
