Yuav ua li cas xaiv pob ntsia hlau txhawb nqa?
Yuav Xaiv Li CasPob Pob Ntsia Hlau Txhawbs? Qhov no yog lus nug ntau tau nug los ntawm ntau tus neeg siv khoom. Raws li tus xa khoom tshwj xeeb tshwj xeeb hauv kev tsim cov pob ntsia hlau txhawb nqa thiab cov neeg muaj ntau tus neeg muaj kev pabcuam txo qis vim yog xaiv cov qauv kev txhawb nqa tsis ncaj ncees lawm.Pob Pob Ntsia Hlau Txhawbs ua raws li "ruaj khov foundation" rau lub hau ntswj, thiab lawv cov ntsia hlau, thiab lawv cov ntsia hlau ncaj qha ntawm cov ntsia hlau thiab kev ua tau tag nrho ntawm cov khoom siv. Niaj hnub no, peb yuav sib tham hauv kev nthuav dav yuav ua li cas xaiv pob ntsia hlau txhawb nqa.
Ua ntej, xaiv raws li cov khoom muaj nqis thauj: phim "cov khoom yuav tsum tau ua" ntawm pob ntsia hlau
1. Axial thauj khoom - dominated scenarios: ua ntej angular tiv tauj cov kabmob npas
Thaum lub pob ntsia hlau feem ntau cov axial loads (piv txwv li cov kabmob tsis tshaj 70% thiab tus nqi sib cuag lub pob bearings yog qhov kev xaiv zoo tshaj plaws. Cov kabmob no tuaj yeem tiv thaiv axial txav los ntawm kev kho lub preload, thiab thaum ntsia hauv lub ntsej muag benirectional, lawv tuaj yeem tiv thaiv axial thauj khoom, ua kom muaj kev ua haujlwm Axial thaum lub sijhawm ua haujlwm.
Piv txwv li, hauv lub tshuab dhos cnc Los ntawm kev kho lub preload kom tswj tau cov Axial tshem tawm tsis pub dhau 0.01 hli, ua qhov raug yog txhim kho.
2.
Yog hais tias lub pob ntsia hlau yog raug rau cov khoom lag luam radial tseem ceeb (piv txwv li angular christian), ib qho angular child tuaj yeem poob peev xwm thauj khoom muaj peev xwm. Nyob rau hauv cov xwm txheej zoo li no, kev sib xyaw ua ke ntawm tob groove pob bearings (rau radial loads) thiab wrust bearings (rau axial loads) tuaj yeem siv. Lub radial rated dynamic thauj khoom muaj peev xwm ntawm cov sib sib zog nqus groove pob bearings yuav tsum yog tsawg kawg 30% siab dua li qhov tseeb radial thauj.
Rau lub pob ntsia hlau nyob rau hauv ib qho kev siv xov tooj hluav taws xob tawm, qhov twg cantilever Long ncav tau li ntawm 19500 n) thiab 51106 thrust bearings yog xaiv. Qhov kev teeb tsa no sib ntsib cov kev txhawb nqa radial thaum ua kom pom tseeb qhov raug.
Thib ob, xaiv raws li qhov yuav tsum tau muaj: Ntsib cov "precision" ntawm pob ntsia hlau.
1. Siab {{- precision scenarios (C5 Qib thiab saum toj no): Xaiv P4-Qib Bearings nrog Rigid Cov Rooj Zaum Rigid.
Rau cov ntawv thov xws li cov cuab yeej ua haujlwm thiab ntsuas cov hmoov txhuas uas yuav tsum tau raug xaiv los ntawm cov pob zeb cam khwb cia (xws li 0.01 hli
TusPob Pob Ntsia Hlau Txhawbntawm lub cav litaograph siv P4-qib Angular sib cuag pob bearings thiab ib qho kev sib txuam ua rau kev txhawb nqa kev txhawb nqa puag. Los ntawm cov kev sib tsoo kom zoo nkauj, qhov sib tsoo ntawm cov kabmob tog lub qhov cub yog kom muaj zog tsawg dua lossis sib npaug rau cov ntsia hlau ua kom ncav cuag ± 0.0005mm.
2. Cov ntawv thov cov kev ntsuas ntshav) (C5-C7 Qib): P5-qib Bearings nrog cov qauv txhawb nqa tuaj yeem raug xaiv.
In general machine tools, conveying equipment, and other applications with low precision requirements (positioning accuracy<=0.05mm/m), P5-grade bearings (rotational accuracy<=0.01mm) with aluminum alloy or cast iron standard support bases can meet the requirements, eliminating the need for excessive pursuit of high-precision configurations and reducing costs.
Lub ntim tshuab lub pob ntsia hlau siv C7-qib Precision, ua khub nrog P5-qib sib sib nqus nqus pob Groovings thiab Stamped Steel phaj txhawb nqa nkhaus. Thaum lub sijhawm ua haujlwm, txoj kev ua yuam kev nyob ruaj khov tsis pub dhau 0.03 mm / m, tag nrho cov cuab yeej xav tau.
Thib peb, xaiv raws li chaw teeb tsa: Haum rau "cov kev txwv cov qauv" ntawm cov khoom siv.
1. Txwv tsis pub tshaj tawm cov xwm txheej: Xaiv cov chav pab txhawb kev compact.
Thaum cov cuab yeej teeb tsa tau txwv (xws li cov me me lossis cov khoom siv kho mob), cov kev sib xyaw ua ke. Cov koog no sib xyaw ua ke, cov rooj zaum ntawm cov rooj zaum, thiab cov ntsaws ruaj ruaj rau hauv ib chav tsev, txo cov qhov ntev los ntawm 30% piv rau kev sib txuas ua ke.
Piv txwv li, pob ntsia hlau ntawm cov neeg hlau phais me me tau muaj kev teeb tsa qhov chaw uas lub cheeb ntawm tsuas yog 30 hli. Kev tsim cov qib kev txhawb nqa nrog lub cheeb ntawm 25 mm tau xaiv, thiab los ntawm kev sib xyaw ua ke ntawm cov kabmob thiab lub pob ntsia hlau ua tiav, sib ntsib cov cuab yeej siv miniaturization.
2. Cov xwm txheej loj dua: Ntxiv cov kev txhawb nqa hauv nruab nrab
Thaum cov txhuas ntev ntev tshaj 3 meters lossis qhov ntev-}} Cov ntsia hlau uas nyob deb tshaj li nws tus kheej qhov hnyav. Cov kev txhawb nqa nruab nrab feem ntau siv cov zawv zawg bearings lossis tus kheej-}} Kev txwv tsis pub muaj kev tiv thaiv me (feem ntau tswj tau nyob rau hauv L / 1000, qhov twg l yog qhov chaw txhawb nqa).
Plaub, xaiv raws li kev ua haujlwm ib puag ncig: tawm tsam sab nraud "kev cuam tshuam loj"
1. Harsh chaw, av noo): Xaiv cov kev txhawb nqa thiab corrosion- Cov ntaub ntawv resistant.
Nyob rau hauv plua plav kev cob qhia (piv txwv li, khoom siv min65 lossis cov khoom noj khoom haus), thiab cov khoom noj khoom haus), thiab cov khoom noj kom muaj zog), thiab cov khoom noj kom huv, 304) lossis yauv ua kom huv si. (Ntsev tshuaj tsuag kev ntsuas ntau dua lossis sib npaug li 500 teev).
Tus Pob Pob Ntsia Hlau Txhawb Ntawm ib tug muaj qee yam dej ua khoom lag luam ua cov khoom siv stainless hlau uas vaj tsev nrog roj hmab ntsaws ruaj ruaj. Tom qab ob xyoos ntawm kev siv nyob rau hauv ib puag ncig nrog ntev raug rau dej noo, tsis muaj xeb lossis coj tau tshwm sim.
2. High-temperature environments (>80 DEGREE): Xaiv siab - kub- Resistant bearings thiab roj nplua nyeem.
Thaum kev ua haujlwm kub tshaj 80 degree, siab {} {{{{{{{{{} {{} { Cov roj nplua nyeem yuav tsum siv lithium - raws qhov kev txhawb nqa siab dua lossis sib npaug nrog kev txhawb nqa lubrication tsis ua haujlwm.
Lub pob ntsia hlau nyob rau hauv lub tshuab molding yas ua haujlwm ntawm 120 degree. Kev txhawb nqa bearings yog kho nrog siab - kub thiab ua khub}}}} deb tshaj li 3,000-teev sia ntawm cov qauv sia.
Qhov thib tsib, xaiv raws li cov txheej txheem Tegoad: Tswj cov "rigidity thiab kev tshem tawm" ntawm kev txhawb nqa.
1. High {{{- precione kev sib kis tau: xaiv qhov nruab nrab siab preload lossis tsis tu ncua preload.
Lub zog siab tshaj plaws ntawm kev siv hluav taws xob tsis tu ncua los ntawm kev hloov pauv lossis cov ntaub ntawv sib txawv, nrog cov kev hloov pauv ceev), nrog cov kev hloov pauv hluav taws xob nrawm), nrog cov khoom siv nyiaj ntau ntxiv tsis pub dhau ± 5%; txoj hauj lwm - Raws li preloading ua tiav qhov kev sib tsoo ntawm cov kabmob sab hauv lossis lwm yam kev ua haujlwm zoo siab (piv txwv li kev sib koom tes ua ke tsawg dua lossis sib npaug rau 3%.
Kev sib tsoo kom precision sib tsoo tshuab siv txoj haujlwm - based teloading rau nws lub pob ntsia hlau ntawm 200 n los ntawm kev sib tsoo lub nplhaib sab nraud ntawm cov kabmob. Qhov thim rov qab ntawm cov ntsia hlau yog tsawg dua los yog sib npaug rau 0.001 hli, ua tau raws li cov kev xav tau daim iav sib tsoo.
2. Tsawg {{{{}} Kev Daim Ntawv Tso Kev Txiav Tawm: Xaiv Bearings nrog Clearance txhawb
Rau cov cuab yeej siv nrog kev ua haujlwm tsis kam ua haujlwm (piv txwv li, tsis siv neeg cov khoom siv tau los txo cov kabmob sib tov (feem ntau tswj hauv qab 0.5 N· m). Txawm li cas los xij, qhov kev tshem tawm yuav tsum tsis pub dhau 0.02 mm kom tsis txhob cuam tshuam kev sib kis mob smoothness.
Nyob rau hauv qee lub zawv zawg siv tsis siv neeg, ib qho kev pom tseeb - Hom Hom sib sib zog nqus Groove npas kabmob tau xaiv rau lubPob Pob Ntsia Hlau Txhawb, txo cov kev sib txhuam kom zoo nkauj rau 0.3 txhiab, ua txoj haujlwm kev ua haujlwm ntau dua. Tsis tas li ntawd, radial txav ntawm cov ntsia hlau tau tswj los ntawm kev taug qab- pab txhawb nqa.
Lub ntsiab
XaivPob Pob Ntsia Hlau Txhawbs yog lub ntsiab lus hais txog "ntsuas thiab txuam nrog ntau yam" {{{} Cov kev txwv tsis pub muaj, thiab kev daws teeb meem preload, thiab cov kev daws teeb meem preload, thiab cov kev daws teeb meem kev ua haujlwm. Kev xaiv tsis raug yuav ua rau nws poob ntawm ntsia hlau precision, txo kev ua haujlwm rau lub neej, lossis txawm tias cov cuab yeej ua tsis tiav.
