Dab tsi yog knurled xovxwm-hauv log studs?
Knurled Xovxwm-Nyob hauv Log Studs yogtshwj xeeb engineered fastenersuas yog nias rau hauv ua ntej- tshuab bores nyob rau hauv lub log hubs, nres rotors thiab ncua kev kawm ntawv yam tsis tas yuav tsum tau threaded kev koom tes los yog vuam. Lub shank ntawm txhua lub log stud yog knurled los tsim ib tug neeg kho tshuab interlock nrog tus tswv tsev khoom. Qhov no kis tau lub clamping quab yuam radially thiab tiv thaiv rotational slippage nyob rau hauv siab torque. Thaum lub sij hawm sib dhos xovxwm- nyob rau hauv lub log studs yog haum thiab yog nce ua hauj lwm nyob rau hauv lub tsheb fais platforms, carbon fiber log inserts thiab lub teeb yuag chassis lug, es tsis yog tus qauv threaded log studs uas cojib nutlos ntawm lwm sab.
Nias -fit vs. threaded studs
Knurled log studs, pob zeb diamond-patterned shank. Thaum nias- haum, lub knurled profile hloov cov khoom nyob rau hauv lub bore phab ntsa,
tsim kom muaj kev cuam tshuam - haum tuav uas threaded interface tsis tuaj yeem sib phim.Vim li cas cov neeg tsim qauv xaiv lub log no rau cov ntawv thov:
1. Radial load faib nres stud taug kev
Tsuas yog axial clamping ua haujlwm rau threaded log studs. Tom qab nres rotors txias, stud wander txo clamping load. Kev nthuav dav sib txawv ntawm steel stud thiab aluminium hub ua rau stud wander. Cov xovxwm - haum log stud nrog knurled shank tiv thaiv qhov no vim hais tias radial cuam tshuam tuav lub zog tuav zoo tsis hais txog ntawm axial preload.
2. Kev ruaj khov muag muag / sib xyaw cia
CFRP log inserts, aluminium-cov ntawv chassis txhawb nqa, thiab magnesium log hubs raug tshem tawm siv siab -torque threaded studs. Txij li thaum nws kis tau kev tuav pov hwm thoob plaws qhov bore nto, Knurled Xovxwm-Nyob hauv Log Stud yog qhov zoo tagnrho rau Motorsport thiab siab - tsheb fais fab nrog cov log sib xyaw.
3. Tsis muaj -rov qab kev co kev ruaj ntseg
Kev ua liaj ua teb, kev lag luam, thiab kev tsheb ciav hlau dov Tshuag threaded fasteners loosen vim kev co. Knurled log stud mechanically interlocks los tiv thaiv rov qab thiab cov khoom puas. Kev sib ntsibISO / TS 16949 cov kev cai zoo.
Xaiv cov khoom siv rau Knurled Xovxwm-Nyob hauv Log Studs
Kev xaiv cov khoom siv ncaj qha tswj hwm lub neej qaug zog, tiv thaiv corrosion, thiab nias - haum rau qhov xav tau ntawm txhua lub log stud. TSEEM CEEB-CNC tshuab kev cai log studs los ntawm peb tsev neeg cov khoom tseem ceeb:

Nias -Fit Installation: Interference Engineering Done Right
Kev cuam tshuam ntawm kev cuam tshuam haum,bore nto polishedthiab installation ceev ntawm knurled xovxwm- nyob rau hauv lub log stud kev ua tau zoo. Cov no txheeb xyuas cov xovxwm txhim khu kev qha- haum lub log stud los ntawm ib qho uas rov qab tawm hauv qab load.
Interference haum xam
Lub diametrical cuam tshuam ntawm steel log stud nyob rau hauv ib tug txhuas hub yog 0.06-0.16 hli ntawm txhua sab. Rau kev sib xyaw, kev cuam tshuam yuav tsum yog 0.01-0.03 hli los tiv thaiv fiber ntau delamination. TSEEM CEEB-CNC lub tuam tsev technical qhia txog qhov ntau thiab tsawg thiab cuam tshuam rau txhua qhov kev txiav txim ntawm kev cai log studs raws li cov khoom sib xyaw ua ke.
Txoj Kev Txhim Kho
- Hydraulic xovxwm. Feem ntau siv rau ntim ntau lawm. Stepped mandrels quab yuam lub log studs rau hauv lub bores kom tswj qhov tob.
- Pneumatic arbor xovxwm: txhim khu kev qha qhov tob thiab lub sijhawm voj voog nrawm rau nruab nrab ntim khiav.
- Expansion haum (kub): Lub hub ntawm lub hub yog rhuab mus rau 80-120℃thiaj li hais tias lub log stud yuav muab tso rau hauv thiab tuav thaum lub rooj sib txoos txias.
Zoo heev rau cov khoom sib xyaw thaum muaj kev cuam tshuam yog qhov teeb meem.
- Sonic / Ultrasonic insertion: Ib txoj kev quab yuam tsawg rau cov ntaub ntawv nkig los yog muab tso rau qhov tseeb.
Cov lus nug nquag nug txog Xovxwm-Nyob hauv Log Studs
Q: Puas yog nias- haum log studs tshem tau thiab rov nruab dua?
A: Tshem tawm cov xovxwm knurled- hauv lub log stud rhuav tshem kev cuam tshuam thiab tiv thaiv rov siv dua. Kev pabcuam- cov qauv hloov pauv tuaj yeem siv lub xub pwg nias- haum nrog lub flange xoob. KEY-CNC cov neeg ua haujlwm engineering tuaj yeem ntsuas koj qhov kev xav tau kev pabcuam.
Q: Dab tsi yog tus tswv tsev tiv thaiv qhov tsawg kawg nkaus phab ntsa thickness?
A: Ib txoj cai yooj yim yog 2.5 × lub knurl txoj kab uas hla raws li phab ntsa thickness. Rau cov khoom siv txhuas hauv qab no thaiv qhov thaiv, KEY-CNC qhia txog steel liner lossis cua sov- teeb threaded insert rau log studs.
Q: Lub caij ntuj no txoj kev thiab ntug hiav txwv nto tiav cov lus pom zoo?
A: 316 stainless steel with passivation or zinc-nickel electroplating on carbon steel are best for chloride-rich conditions. Both meet ASTM B117 salt spray resistance >500 teev.
Q: Puas yog KEY- CNC sib dhos?
A: Raws li ib feem ntawm nws ib qho - nres kev tsim khoom, KEY-CNC nias lub log studs rau cov neeg siv khoom- muab los yog KEY- muab lub log hubs, nres rotors, thiab chassis brackets. Tag nrho cov ntawv ntxig yog ISO 9001-tswj.
