Cov thev naus laus zis thiab cov ntsiab lus tseem ceeb rau cov ntsiab lus ceev ceev
- Yuav ua li cas xaiv lub zog ntawm bolts nyob rau hauv lub nrawm nrawm, thiab dab tsi yog kev sib raug zoo nrog kev khiav hom thiab thauj khoom?
Rau kev kub siab ib txwm (ceev tsawg dua lossis sib npaug nrog 120km / h), 8.8 -}}}}} bolts feem ntau xaiv. Lawv lub zog tensile yog 800MPA thiab tawm lub zog thiab lub zog, uas tuaj yeem tiv thaiv cov thauj khoom ntawm cov tsheb ciav hlau qub. Rau siab - Ceev ntau dua kev tsheb ciav hlau (nrawm dua los yog sib npaug ntawm cov tsheb ciav hlau, {9 {9 {9 {{9 {9 {9 {9 {9 {}}}}}}} polts feem ntau siv. Lub zog tensile of 10.9 -}}}} pa bolts yog 900mpa thiab paib lub zog yog 900mpa, ntsib cov kev xav tau ntawm high- kev ua haujlwm ceev. Rau hnyav - haul railways (qag thauj khoom loj dua los yog sib npaug rau 25t), uas yuav tsum tau ua haujlwm loj,} {}}} Lawv lub zog tensile yog 1200Mpa thiab tawm lub zog yog 1080MPA, kom ntseeg tau qhov ruaj khov ntawm cov qauv sib luag.
- Lub anti -} loosening kev ua tau zoo yog qhov tseem ceeb heev rau kev nrawm. Hom hom twg ntawm anti -} xoob neeg rau khoom thiab lawv cov hauv paus ntsiab lus yog dab tsi?
Kev nquag ov {-} loosening txiv ntoo suav nrog nylon - lawb txiv ntseej. Lub tsho nylon yog embedded nyob rau hauv lub txiv ntoo. Thaum nruj, cov ntiv tes nylon ze rau cov ntsia liaj qhov rooj los tsim kev sib txhuam rau anti- loosening. Muaj kuj flange - Cov ntsej muag ntsej muag ntawm thaj chaw ntawm lub txiv ntoo thiab txuas lub siab, thiab txhim kho lub zog anti {{} {xoob nyhuv. Tsis tas li ntawd, muaj cov txiv ntoo txaws nrog cais cov pins rau anti - loosening. Tom qab lub txiv ntoo yog slotted, ib tug sib cais tus pin yog tso rau tiv thaiv cov txiv ntseej los ntawm kev hloov chaw uas muaj qhov ntev ntawm {}} lub sij hawm ruaj khov ntawm cov nrawm.
- Cov tshuab ntxhua khaub ncaws ua si hauv kev sib tw nrawm, thiab dab tsi yog qhov sib txawv ntawm cov khoom siv sib txawv (cov tshuab ntxhua khaub ncaws, lub caij nplooj ntoo hlav ntxhua khaub ncaws, thiab lwm yam)?
Cov hniav txuas ncaj tuaj yeem nce thaj chaw tiv tauj ntawm cov txiv ntoo thiab txuas nrog lub siab, thiab tiv thaiv qhov chaw txuas los tiv thaiv khawb thaum rub tawm cov txiv ntoo. Lawv yog qhov haum rau kev dav dav scenarios. Spring washers use the reaction force generated by their own elastic deformation for anti - loosening and are used in parts with vibration but relatively small vibration. Cov ntawv ntxhua khaub ncaws muaj peev xwm muab cov nyiaj tiv thaiv loj loj thiab haum rau qee zaus uas yog qhov ua ntej ua ntej ua ntej lub zog yog qhov yuav tsum tau ua thiab muaj ib qho kev co. Cov khoom siv sib txawv yog qhov tsim nyog xaiv raws li qhov xav tau los txhim kho kev ua haujlwm ntawm lub nrawm nrawm.
- Thaum lub installation ntawm lub nrawm nrawm, yuav ua li cas kom ntseeg tau torque ntawm bolts ua tau raws li txoj kev yuav tsum tau ua, thiab txoj kev kuaj pom zoo li cas?
Thaum lub sij hawm installation, lub pob hluav taws xob hnyav yog siv los teeb zawm torque tus nqi raws li cov qauv tsim. Piv txwv li, thaum M24 Bolts yog siv rau kev kub siab ib txwm, lub zog yog tswj hwm ntawm {2} · m. Cov hau kev kuaj pom muaj xws li cov txheej txheem torque, ncaj qha siv lub zog ntswj txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau ua rau tus qauv; and the marking method, making a mark at the connection between the bolt and the nut and regularly checking the position of the mark to determine whether the nut is loose, ensuring the installation quality of the fastening system.
- Thaum lub sijhawm ntev - siv siv, cov teeb meem nrawm nrawm, thiab ua li cas kev tu cev thiab hloov?
Thaum lub sijhawm ntev -}}}} siv xws li bolt loosening, cov txiv ntseej puas yuav tshwm sim. Thaum lub sijhawm saib xyuas, saib xyuas cov torque thiab retightening qhov xoob xoob nrog lub zog ntswj. Hloov cov txiv ntoo stripped thiab cov tshuab raj puas raws sijhawm. Thaum hloov chaw, xaiv cov khoom siv ntawm tib qho kev qhia tshwj xeeb thiab ua haujlwm raws li cov txheej txheem txheej txheem txheej txheem ntawm cov txheej txheem nrawm thiab tswj hwm qhov ruaj khov ntawm cov qauv sib luag.
