Dab tsi yog cov suab nrov ntawm pob screws?
Hav! Raws li tus kws pab tswv yim tshaj lij hauvPob Screws, Kuv tau nug txhua hnub los ntawm cov neeg siv khoom: "Kuv lub cim tshuab lub pob ntsia hlau yog nrov dhau thaum ua haujlwm?" "Kuv hnov pob cov duab tawm yog nrov dua Trapezoidal Screats - Puas muaj tseeb?" Nyob rau hauv kev muaj tiag, lub suab nrov ntawm ib lub pob ntsia hlau tsis yog tus nqi txawb. Ib yam li lub suab nrov lub tsheb ua rau thaum tsav tsheb nyob ntawm tus qauv, thiab nrawm nrawm, thiab kev sib hloov ceev,- ib coPob ScrewsKhiav ruam dua li lub tsev qiv ntawv (tsawg dua los yog sib npaug ntawm 45db), thaum lwm tus muaj kev ua lag luam tsis zoo (> 70dB). Niaj hnub no, ua raws li cov txheej txheem tiag tiag uas peb siv los pab cov neeg muaj teeb meem suab nrov nrov, Kuv yuav siv cov teeb meem uas koj tau zais los ntawm "zais cov suab nrov" ntawm pob ntsia hlau nrov. Qhov no yuav pab koj xaiv lub pob ntsia hlau uas yog qhov ntsiag to thiab txhim khu kev qha.
Kauj ruam 1: Lub sijhawm 8-kauj ruam qhia tswv yim kom nkag siab pob pob ntseg qib
Ua ntej tshaj, txhais koj cov xwm txheej "project yuav tsum tau" {{{{{{{{{{{{{{} {}} paub cov khoom lag luam nrov nrov nthuav qhia cov tseem ceeb.
Txhawm rau kom nkag pob ntsia hlau cov suab nrov, koj yuav tsum xub nkag siab qhov twg koj cov khoom siv yuav raug siv thiab suab nrov ntau npaum li cas. Qhov no tiv thaiv kev muag muag nrhiav ntawm "ultra-} ntsiag to" daws teeb meem uas cov khoom pov tseg:
Dab tsi ib puag ncig koj cov khoom lag luam ua haujlwm hauv?
Rau cov suab nrov - Cov chaw teeb tsa zoo li cov lab lossis cov cuab yeej kho mob, pob ntseg pob ntseg yuav tsum tsawg dua lossis sib npaug rau kev sib tham ib txwm).
Koj lub suab nrov tshaj plaws yog dab tsi?
Puas yog "ua tiav cov suab nrov tshem tawm" (tsis yooj yim sua, tsuas yog txo tau yog ua tau), lossis "tsis muaj kev cuam tshuam nrog cov haujlwm ua haujlwm"? Cov khoom lag luam feem ntau tsuas yog xav tau "tsis - paned sib tham" (tsawg dua lossis sib npaug rau 45dB ntawm tus nqi them.
Kauj Ruam 2: Tshuaj xyuas "pob ntsia hlau cov khoom thiab cov qauv"- Cov ntaub ntawv zoo dua thiab tsim qauv zoo rau cov suab nrov
Lub pob ntsia hlau cov khoom siv thiab cov qauv tsim lub hauv paus ntawm "kev ua haujlwm ntsiag to." Cov ntaub ntawv qis dua lossis cov qauv tsim txom tuaj yeem tuaj yeem muab cov suab nrov me ntsis:
Increased clearance soon causes "impact noise," making it 10-15 dB louder than SUJ2 steel screws. Ball roundness tolerance is also critical. High-precision balls (roundness ≤0.0005mm) produce 5-8dB less noise than standard balls (tolerance >0.001 hli).
Pob Ntawm Cov Qauv Qauv
Sab hauv ncigPob ScrewsPom cov khoom hauv cov ntsia hlau lub cev, txo cov kev cuam tshuam thaum lub sijhawm ua haujlwm thiab txo lub suab nrov los ntawm 8} 12} sib piv rau cov kev tsim sab nraud. Sab hauv ncig screws ua 55db suab nrov, thaum sab nraud ntawm cov screen tej zaum yuav ncav cuag 65db vim tias sab nraud ntawm lub raj hauv kev ncig ua si, tsim lub suab nrov ntxiv. High-Endes ntsiag to pob screws kuj sib xyaw "ntawm cov kev sib tw ua ntu zus los txo cov suab nrov, txo qis dua 3-5db ntxiv.
Kauj ruam 3: Kev ruaj ntseg "pob ntsia hlau qhov ntev thiab cov tsis sib haum" - qhov loj me, suab nrov hauv kev txwv
Pob ntsia hlau qhov ntev thiab cov tsis ncaj ncaj ncaj qha cuam tshuam cov suab nrov qib. Nws tsis yog hais txog "Loj dua yog qhov zoo dua," tab sis theej "meej phim":
Cov hmoov hlau loj dua ntawm cover thiab suab ciav los txhim kho kev ua haujlwm, txo txoj kev ua haujlwm "kev co":Cov suab me me slows ua rau dov nrawm, qis suab nrov: lub suab nrov dua:
Kauj Ruam 4: Ntsuas "pob ntsia hlau ua qhov tseeb thiab zoo nkauj" {{1} kub siab, du nto, suab nrov
Coob tus ntseeg "precision thiab nto tsis muaj kev cuam tshuam suab nrov," tab sis qhov no tsis muaj tseeb. Screws nrog cov tsis muaj tseeb thiab ntxhib cov chaw tsim ua suab nrov dua siab dua:
Qhov no vim tias qhov tsis sib xws ntawm qhov qis - pretion} Precision screws ua rau "sticking" thaum lub pob dov, tsim tawm suab nrov ntxiv. Ib tus neeg muas zaub tau xaiv yav dhau los rau qhov pheej yig dua c10-qib ntsia hlau ntawm 68DB nrov. Tom qab hloov mus rau C7-qib ntsia hlau, cov qib suab nrov poob mus rau 56db, ua rau pom kev sib tw pom.
Nto tas qhov saum npoo ua tiav ntawm txhuas ntsia hlau ncej thiab runkeways yuav tsum tau tshaj li 0.4μm. Ua tiav tiav txo cov coefficients (kwv yees}. 0.001-0.002), qis suab sib piv rau RA 1.6μm screws. Nto khawb lossis burrs nce kev sib txhuam tiv thaiv, raising suab los ntawm 5-8dB.
Kauj ruam 5: Xav txog "installation thiab compatibility" -}} tsis muaj kev sib txuas lus tuaj yeem ua rau cov ntsia hlau ntsiag to
Pob ntsia hlau teeb tsa yog qhov tseem ceeb rau kev tswj hwm nrov, muaj ntau cov teeb meem suab nrov los ntawm kev teeb tsa tsis raug:
Coaxiality installation installation ntawm coaxiality ntawm tus ntsia hlau ncej thiab lub tsheb hlau yuav tsum tau tswj tsis pub dhau 0.02mm. Tshaj li qhov kev ua siab ntev no ua rau cov ntsia hlau mus rau "khi," haub pev thiab nce suab los ntawm 10- 15db. Ib tus neeg muas zaub tau 0.06mm coaxiality nrog 72dB suab nrov. Tom qab ntsuas rau 0.01mm siv cov cuab yeej laser sib txawv, lub suab poob mus rau 58dB. Yuav tsum siv cov cuab yeej tshaj lij rau calibration {{{} Tsis txhob cia siab rau kev tshuaj xyuas ntau dhau los ntawm kev tsis zoo.
Kev kho dua tshiab Preload
Cov kev npaj khoom tsim nyog tshem tawm tshem tawm ntawm cov pob thiab radewsays, tiv thaiv "backlash suab nrov." Txawm li cas los xij, ntau preload loj dua kev sib txhuam, paradoxically tau tsa suab nrov.
Txhawb kev teeb tsa
Ob npaug -}} {{- 8 3}} tsau / ib-floating kev teeb tsa. Qhov no txo qis "kev co" ntawm cov ntsia hlau, tiv thaiv kom muaj suab nrov ntxiv los ntawm kev co.
Kauj Ruam 6: Haum rau "Kev ua haujlwm thiab lubrication" {- kev cuam tshuam rau lub suab sib cuam tshuam lub suab
Harsh qhov chaw nyob thiab cov khoom tsis txaus Lubrication tsa pob ntsia hlau nrov thiab tej zaum yuav ua rau Lifes Lifesth:
Ib puag ncig huv si
Plua plav lossis paug ib puag ncig tso cai rau cov lus kom cov khoom ntim ntawm cov pob thiab khoom plig. Qhov no "xuab zeb hauv bearings" cov txiaj ntsig tsis sib npaug txhuam, nce suab nrov los ntawm 8-12dB. Piv txwv li, pob ntsia hlau hauv chav ua dej ua haujlwm ntawm 55db, thaum tib tus qauv hauv plua plav Rhiav ncav 65db. Txhim kho cov hmoov av npog txo cov suab nrov rau 58DB.
Lubrication li cas
Li niaj hnub lubrication txo kev sib txhuam thiab cov khoom lag luam qis:
Pob ScrewsSiv high -} kub roj ua haujlwm 10-15db quietle tshaj li tsis muaj cai. Tsis txaus ua rau "kev sib txhuam qhuav," nrov nrov nrov. Ib lub ntsia hlau tsim 75DB suab nrov yam tsis muaj lubrication, txo rau 60dB tom qab siv nyiaj. Degreaded roj (tsaus nti los yog clumped) kuj nce kev sib txhuam, raising suab los ntawm 5-7dB piv rau cov khoom siv lubrication. Hloov cov roj kom sai.
Kauj Ruam 7: Txheeb xyuas "pob ntsia hlau zoo thiab ntawv pov thawj" - tsis muaj suab nrov raws li "nyuaj"
Ib coPob ScrewsKev ua lag luam li "Silent qauv" yeej tsim cov suab nrov siab dua, qhia txog cov teeb meem zoo. Thaum xaiv:
Txheeb xyuas cov chaw tsim khoom lag luam daim ntawv qhia cov suab nrov. Cov npe hluav taws xob ntsuas ntsia thawv nrov nyob rau hauv cov qauv ntawm cov qauv (1500 r / min, tsis muaj kev ceeb toom "suab nrov rau 55dB (1500 R / min)". Nqaimardard screws tsis tau kuaj, thiab lawv cov suab nrov yog "theoretical qhov tseem ceeb" uas tej zaum muaj tsawg dua qib los ntawm 10-15dB.
Kauj Ruam 8: Qhov nqi ntsuas thiab lub suab nrov - kev txhoj tsis yog ib txwm zoo dua; Txaus ua tau zoo yog qhov tseem ceeb
