Torque Attenuation Mechanism thiab Ntev -Lub Sij Hawm Los Tiv Thaiv -Loosing Technology ntawm Rail Bolts
Q1: Dab tsi yog qhov tseem ceeb ntawm kev khiav bolt torque attenuation?
A1: Tsheb ciav hlau kev co ua rau micro- plam ntawm lub ntsia liaj qhov rooj qhov chaw, thiab rov ua dua yuav txo qhov kev sib txhuam ntawm cov xov, uas ua rau lub zog torque attenuation; Nyob rau tib lub sij hawm, lub longitudinal quab yuam generated los ntawm rail expansion thiab contraction thiab kub hloov yuav ua rau lub bolts dais tensile thiab compressive alternating kev nyuaj siab, accelerating lub poob ntawm preload thiab aggravating torque attenuation.
Q2: Dab tsi yog qhov txawv ntawm kev tiv thaiv -loosing txoj cai ntawm lub caij nplooj ntoos hlav ntxhua khaub ncaws thiab nylon xauv txiv ntoo?
A2: Caij nplooj ntoos hlav washers tsim kev sib txhuam los ntawm elastic deformation thiab tiv thaiv bolt loosening los ntawm kev sib txhuam tsis kam, haum rau cov pa kab; nylon locking txiv ntseej muab kev xauv lub zog los ntawm extrusion deformation ntawm nylon rings thiab screws, nrog rau kev tiv thaiv ntau dua -loosing nyhuv, haum rau nkhaus thiab turnout seem nrog kev co hnyav.
Q3: Yuav ua li cas cov ntsia liaj qhov rooj lubrication xwm txheej cuam tshuam torque attenuation?
A3: Cov xov kev sib txhuam coefficient ntawm bolts yog siab nyob rau hauv qhuav lub xeev, lub torque yog ib qho yooj yim mus dag siab, thiab qhov tseeb preload yog tsis txaus; Tom qab siv cov xov tshwj xeeb roj, qhov sib txhuam coefficient ruaj khov, kev sib raug zoo ntawm torque thiab preload yog qhov tseeb dua, uas tuaj yeem cuam tshuam torque attenuation thiab txhim kho fastening stability.
Q4: Vim li cas thiaj li muaj kev sib xyaw ua ke los tiv thaiv-loosing tswv yim xav tau rau bolt anti-loosing hauv hnyav- cov kab tsheb?
A4: Lub log- kev tsheb ciav hlau cuam tshuam thiab lub zog ntev yog qhov loj hauv hnyav- cov kab tsheb, thiab ib qho kev tiv thaiv ib leeg -loosing qauv yog yooj yim ua tsis tau; cov txheej txheem kev tiv thaiv kev sib xyaw ua ke sib xyaw ua ke los tiv thaiv kev siv tshuab - xoob thiab xov tiv thaiv -loosing, xws li tus kheej -locking txiv ntseej + locking nplaum + anti- loosening washer, uas tuaj yeem tsim ntau yam kev txwv, tag nrho inhibit bolt loosening thiab xyuas kom muaj kev sib koom ua ke.
Q5: Yuav ua li cas los saib xyuas thiab kho lub bolt torque hauv kev ua haujlwm thiab kev saib xyuas?
A5: Tsis tu ncua siv torque wrenches kom pom -check bolt torque, thiab rov kho cov kab tshiab tshiab ntawm 1 hli, 3 hli thiab 6 hli raws li; rau bolts nrog ntau torque attenuation, ntxuav cov xov ua ntej thiab tom qab ntawd rov qab mus rau tus qauv torque, thiab hloov cov bolts loj heev los yog corroded bolts ncaj qha kom tsis txhob fastening tsis ua hauj lwm.
