Anti-Slip serration tsim ntawm rail bearing phaj thiab nws cov nyhuv ntawm rail lateral restraint
Dab tsi yog cov qauv tsim ntawm cov hniav trapezoidal ntawm lub teb chaws tus qauv siab daim hlau?
Cov hniav trapezoidal ntawm lub teb chaws tus qauv siab daim hlau muaj qhov tob ntawm 1.0mm, ib tug hniav sib nrug ntawm 5 hli, thiab ib tug hniav kaum sab xis ntawm 60 degree. Qhov kev ntsuas no yog qhov zoo tshaj qhov ntsuas tau los ntawm kev ntsuam xyuas kev sib txhuam thiab tuaj yeem ua kom muaj kev sib txhuam ntau tshaj plaws. Cov hniav sab saum toj dav ntawm cov hniav trapezoidal qauv yog 2 hli, thiab cov hniav hauv qab dav yog 3 hli, nrog qhov nqaim - sab saum toj thiab dav - hauv qab qauv, uas tsis yooj yim rau hnav thiab deform, thiab muaj lub neej ua haujlwm ntev. Rau cov phaj siab txhawb nqa 60kg / m rails, tus qauv hniav yuav tsum npog tag nrho cov xovxwm nto kom paub meej tias thaj chaw sib cuag nrog cov tsheb ciav hlau hauv qab yog ntau dua lossis sib npaug li 90% thiab txhim kho cov nyhuv sab nraud. Nyob rau hauv hnyav- txoj kev tsheb ciav hlau, cov hniav qauv qhov tob yuav tsum tsim nyog nce mus rau 1.2 hli, thiab qhov sib nrug ntawm cov hniav yuav tsum tau txo mus rau 4 hli los txhim kho kev sib txhuam thiab hloov mus rau cov kev xav tau ntawm cov tsheb ciav hlau loj loj. Thaum lub sij hawm tsim kho, nws yog ib qho tsim nyog yuav tau xyuas seb cov hniav zoo li cas. Yog tias hnav lossis deformation, lub phaj siab yuav tsum tau hloov raws sijhawm.
Dab tsi los tiv thaiv- qhov zoo tshaj hauv pliaj ua cov qauv hniav pob zeb diamond muaj tshaj cov qauv hniav trapezoidal?
Lub pob zeb diamond hniav qauv yog pob zeb diamond- zoo li tus, thiab kev sib cuag nrog cov tsheb ciav hlau hauv qab yog qhov chaw sib cuag, uas tuaj yeem ua rau muaj kev ntxhov siab ntau dua, thiab kev sib txhuam quab yuam tau nce ntau dua 20% piv nrog cov qauv ntawm cov hniav trapezoidal, nrog rau kev tiv thaiv ntau dua -slip effect. Nws cov hniav qauv qhov tob thiab qhov sib txawv tuaj yeem hloov kho tau yooj yim, nrog qhov tob ntawm 0.8-1.5mm thiab qhov sib nrug ntawm 4-6mm, yoog raws cov ntaub ntawv sib txawv thiab kab ua haujlwm. Lub pob zeb diamond hniav qauv muaj kev ua tau zoo bidirectional los tiv thaiv kev ua haujlwm, uas tuaj yeem tsis tsuas yog tiv thaiv sab laug ntawm txoj kev tsheb ciav hlau tab sis kuj tiv thaiv txoj kev txav mus rau sab xis, ua rau nws tsim tshwj xeeb rau kev siv nyob rau hauv me me-radius nkhaus seem. Lub phaj siab nrog tus qauv tsim qauv no hnav tusyees, tsis muaj qhov hnyav hnyav hauv zos, thiab nws lub neej kev pabcuam yog 15% ntev dua li ntawm cov hniav trapezoidal siab phaj. Nyob rau tib lub sijhawm, cov qauv hniav pob zeb diamond yog ib qho yooj yim los ntxuav, thiab cov plua plav thiab cov khib nyiab ntawm txoj kev khiav tsis yooj yim kom tau daig hauv cov hniav sib txawv, ua kom yooj yim txij nkawm.
Dab tsi tshwj xeeb yuav tsum muaj rau tus hniav qauv tsim ntawm cov phaj siab nyob rau hauv me me - vojvoog nkhaus seem?
Lub zog centrifugal generated thaum lub tsheb ciav hlau hla dhau qhov nkhaus hauv me me - vojvoog nkhaus yog loj. Qhov tob ntawm lub siab phaj hniav qauv yuav tsum tau nce mus rau 1.5 hli, thiab qhov sib nrug ntawm cov hniav yuav tsum tau txo mus rau 3 hli kom ua kom muaj kev sib txhuam ntau tshaj plaws thiab tiv thaiv kev sib tsoo ntawm txoj kev tsheb nqaj hlau. Lub kaum sab xis ntawm cov hniav yuav tsum tau hloov mus rau 75℃txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhuam hniav Nias nto ntawm lub phaj siab yuav tsum tau carburized, thiab lub hardness ntawm lub saum npoo yuav tsum tau nce mus rau saum toj no HRC55 los txhim kho cov hnav tsis kam ntawm tus hniav qauv thiab hloov mus rau qhov tsis tshua muaj kev sib txhuam nyob rau hauv nkhaus seem. Cov qauv hniav yuav tsum npog tag nrho qhov dav ntawm lub phaj siab, thiab qhov chaw sib cuag nrog txoj kev tsheb ciav hlau yuav tsum muaj ntau dua lossis sib npaug li 95% kom tsis txhob muaj siab phaj deformation tshwm sim los ntawm kev ntxhov siab hauv zos tsis sib xws. In addition, the tooth pattern density of the pressure plate on the outer side of the curve should be higher than that on the inner side, with a tooth spacing of 3mm on the outer side and 4mm on the inner side, to specifically resist the outer centrifugal force.
Dab tsi yog qhov cuam tshuam ntawm cov qauv ntawm cov hniav ntawm lub lateral restraint peev xwm ntawm cov phaj siab?
Hniav qauv hnav yuav ua rau kom qhov chaw sib cuag ntawm lub phaj siab thiab txoj kev tsheb ciav hlau, hloov los ntawm kev sib cuag los yog kab sib txuas mus rau qhov chaw sib cuag, ua rau muaj kev sib txhuam loj thiab txo qis dua 50% ntawm lub peev xwm sab nraud. Thaum tus hniav qauv qhov tob yog hnav kom tsawg dua 0.3 hli, lub phaj siab tsis tuaj yeem tiv thaiv kev tsheb nqaj hlau sab nraud, thiab kev tsheb ciav hlau sab nraud yuav tshwm sim thaum lub tsheb ciav hlau hla dhau qhov nkhaus, ua rau qhov ntsuas siab tshaj tus qauv. Tom qab txhuam hniav hnav, qhov meshing℃ntawm lub phaj siab thiab cov tsheb ciav hlau txo qis, thiab slipping yog qhov tshwm sim thaum muaj kev ntxhov siab. Raws li kev ua haujlwm ntev - lub sijhawm, lub phaj siab yuav xoob lossis txawm poob. Cov qauv hniav hnav yog ib qho yooj yim rau cov plua plav thiab cov khib nyiab, ntxiv kom tsis txhob muaj kev sib txhuam thiab ua rau lub voj voog tsis zoo. Tsis tas li ntawd, kev hnav cov hniav yuav ua rau tsis sib xws ntawm kev ntxhov siab ntawm lub phaj siab, ua rau kom qaug zog ntawm lub phaj siab, thiab ua rau lub neej ua haujlwm luv.
Yuav ua li cas txhawm rau txheeb xyuas seb qhov kev tiv thaiv- plam kev ua haujlwm ntawm cov phaj siab ntawm cov hniav ua tau raws li tus qauv?
Siv cov kev sib txhuam coefficient tester los ntsuas qhov kev sib txhuam coefficient ntawm cov phaj siab ntawm cov hniav thiab cov tsheb ciav hlau hauv qab. Kev sib txhuam coefficient Ntau dua los yog sib npaug ntawm 0.6 yog raws li tus qauv, thiab tus nqi siab dua, qhov zoo dua qhov kev ua tau zoo dua los tiv thaiv -. Ua ib qho kev sib tw thrust, siv lub lateral load simulating tsheb ciav hlau tig mus rau lub phaj siab, soj ntsuam qhov kev hloov ntawm txoj kev tsheb ciav hlau sab nraud, thiab qhov kev hloov mus rau sab nraud tsawg dua lossis sib npaug li 0.5 hli yog tsim nyog los xyuas qhov muaj peev xwm tiv thaiv sab nraud. Ntsuas cov hniav qauv qhov tob los ntawm kev tshuaj xyuas qhov muag, siv lub ntsuas qhov tob los ntsuas ntawm qhov sib txawv ntawm cov qauv ntawm cov hniav, thiab qhov nruab nrab qhov tob ntau dua lossis sib npaug li 80% ntawm tus nqi tsim nyog. Yog tias nws qis dua tus nqi no, lub phaj siab yuav tsum tau hloov. Ua ib qho kev kuaj hnav, simulate qhov kev sib txhuam ua haujlwm ntawm kev ua haujlwm ntawm lub tsheb ciav hlau, ntsuas cov hniav qauv coj tom qab 100,000 kev sib txhuam cycles, thiab hnav tsawg dua lossis sib npaug li 0.2 hli yog tsim nyog. Tsis tas li ntawd, ntawm - qhov kev soj ntsuam ntawm qhov chaw tuaj yeem ua tiav los suav cov ntaub ntawv hloov chaw sab nraud ntawm txoj kev tsheb ciav hlau hauv ntu nkhaus thiab ntsuas qhov ua tau zoo ntawm cov hniav qauv los tiv thaiv- plam kev ua haujlwm.
