Technical Specifications:
| Hom tsis ua hauj lwm / Trap | Variant cuam tshuam | Keeb kwm | Kev kuaj xyuas qhov nyuaj | Qhov tshwm sim | |
|---|---|---|---|---|---|
| Dowel xov creep | TXL 15, SKL18 | PA66 so nyob rau hauv load | Torque check nyeem ib txwm; zog low | Rail creep >3 hli / xyoo; CWR buckling risk | |
| Heel hnab tshos spalling | Tag nrho cov pob zeb pw tsaug zog | Txias-thaw + dej nkag | Pocket wide gauge | Clip kev sib hloov; ntiv taw nqa; ceg pob txha | |
| T-bolt dabtsi yog khoov qaug zog | SKL 12 | Tsis yog -perpendicular installation | Torque-lub kaum sab xis saib xwb | Bolt taub hau sib cais; clip ejection | |
| 38Si7 vs 60Si2CrA swb | SKL12/15 export | Mill daim ntawv pov thawj kev dag | XRF zoo tib yam; xav tau OES carbon | Teb chaws Europe: ceev ceev; Suav teb: embrittlement | |
| Xov form mismatch | SKL15 ntsia liaj qhov rooj / dowel | M22 vs 7/8 "-9 UNC tsis meej pem | Xov pitch gauge yuav tsum tau | Hla- xov; 80% rub- tawm poob | |
| Eccentric pin hloov | SKL12 hloov kho | Tsis yog -Vossloh "compatible" mov | Visual: tus pin centered vs offset | Zero gauge adjustment muaj peev xwm |
Performance Range:
Dowel Xov Creep (Invisible)- Plastic dowel threads so hauv qab tensile load. SKL15 ntsia ntawm 200 Nm → tom qab 5 xyoos,residual clamp quab yuam 12-13 kNTxawm tias torque check qhia 200 Nm. Yog vim li cas: kev sib txhuam nce, nro tsis tau. Kev kuaj mob yuav tsum taunqa -tawm xeem( ntsuas quab yuam thaum clip ntiv taw tsuas yog cais los ntawm kev tsheb nqaj hlau).
Heel Hnab Corrosion Widening- Cov dej daig hauv lub xub pwg hnab (pob pw tsaug zog). Txias-thaw cyclesspall hnab tshos ntug 0.2-0.5 hli / xyoo. Kev txhawb nqa pob taws poob → clip rotates nyob rau hauv load → ntiv taw nqa 0.3 hli / voj voog → cuam tshuam fretting → ceg pob txha ntawm 2M cycles (certified 5M). Kev kuaj pom: hnab tsho dav> nominal +2 hli.
Kev Saib Xyuas & Kev Pom Kev Ua Haujlwm
- DIN 17221 vs GB / T 1222 Metallurgy- European SKL:38 ib 7(0.35–0.42% C), ductility- tsom. Suav SKL:60 Si2CrA(0.56–0.64% C), lub zog - tsom.Tsis sib npaug. 38Si7 nyob rau hauv siab- ceev Suav txoj hauv kev → ceev ntiv taw hnav (softer). 60Si2CrA hauv European qhov → hydrogen embrittlement txaus ntshai (siab dua hardness, Zn embrittlement susceptible).
- M22 Xov Form Tsis meej pem- SKL15 qhiaM22-6gntsia liaj qhov rooj,M22-6Hdowel. Metric ntxhib:2.5mm qhov siab. AREMA 7/8 "-9 UNC:9 TPI (2.82 hli). Kev yuav khoom yuam kev: xaj "M22" los ntawm North American tus neeg muag khoom → tau txais7/8"-9 UNC(21.9 hli OD, 2.82 hli suab). Thawj 3 threads koom nrog, ces jams. Hla -threading guaranteed.
- SKL12 Eccentric Pin Regional Monopoly- Kev hloov kho tom qab ntawmeccentric taper pinyog tswv rauVossloh SKL12 Zw700 system. Zoo tib yam-saib SKL12 los ntawm lwm cov tuam ntxhab muajconcentric pin→ tsis muaj kev hloov kho. Ordered li "SKL12 tau tshaj" → xa tsis tau - kho tau → qhov chaw tsis lees paub 100%.
