Dab tsi yog Kev Sib Raug Zoo Ntawm Pob Ntsia Hlau Preload thiab Axial Clearance? Yog vim li cas siab dua Preload tsis yog ib txwm zoo dua
Axial Clearance cuam tshuam rau qhov kev hloov pauv rov qab
Thaum lub pob ntsia hlau hloov nws cov kev taw qhia ntawm kev txav, axial clearance nruab nrab ntawm cov txiv ntoo thiab ntsia hlau raceway tuaj yeem ua rau ncua sij hawm ntawm lub cev muaj zog thim rov qab thiab lub rooj txav tiag tiag. Qhov kev ncua no hu uarov qab backlash yuam kev.
Rau cov cuab yeej siv khoom siv dav dav, qee qhov kev tshem tawm yuav raug lees txais. Txawm li cas los xij, kev siv xws li:
CNC tshuab cuab yeej
Precision ntsuas platforms
Bidirectional positioning systems
feem ntau xav tau ntau me me axial hloov thaum lub sij hawm thim rov qab.
Yuav Ua Li Cas Preload Txhim Kho Pob Ntsia Hlau Rigidity
Preloadtxhais tau hais tias siv cov kev tswj hwm sab hauv nruab nrab ntawm cov khoom thiab cov kev sib tw ua ntej cov khoom ua haujlwm sab nraud raug siv.
Lub hom phiaj ntawm preload yog:
Txo lossis tshem tawm axial clearance
Nce axial txhav
Txhim kho qhov chaw teb nyob rau hauv load
Cov txheej txheem preload muaj xws li:
Muab ob npaug rau txiv ntseej preload siv spacer hloov
Lead offset preload
Tswj lub pob loj xaiv
Qhov tseeb preload qauv nyob ntawm qhov tshwj xeeb pob ntsia hlau tsim thiab cov chaw tsim khoom cov khoom lag luam.
Yog vim li cas siab dua Preload tsis yog ib txwm zoo dua
Kev nce preload nce lub zog sib tiv tauj nruab nrab ntawm:
Pob
Kev sib tw
Txiv ntseej Cheebtsam
Yog li ntawd, nws kuj nce:
Khiav torque
Kev sib txhuam kub
Lub cev muaj zog load
Ntau dhau preload tuaj yeem ua rau:
Txo qaug zog lub neej
Lub lubricant deterioration sai dua
Nce load ntawm motors thiab couplings
Ua haujlwm kub dua
Yog li, preload yuav tsum tau xaiv raws li:
Qhov siab tshaj plaws axial load
Yuav tsum tau rigidity
Kev khiav hauj lwm ceev
Thaum tshav kub kub dissipation tej yam kev mob
Yuav tsum tau kev pab lub neej
Lub hom phiaj tsis yog kom ua tiav qhov ua ntej, tab sis kom ua tiav qhov tseeb qhov sib npaug ntawm qhov nruj, qhov tseeb, thiab kev ntseeg tau.
Preload Torque yog qhov taw qhia ua haujlwm tseem ceeb
Lub pob ntsia hlau preloaded yuav tsum muaj qee yam ntawm torque kom tig nyob rau hauv tsis muaj lwm yam load. Qhov nodynamic preload torqueyog ib qho tseem ceeb soj ntsuam parameter.
Torque tus nqi thiab kev hloov pauv tuaj yeem qhia tau tias:
Pob ncig mob
Txoj kev sib tw
Kev sib dhos zoo
Yog tias qhov tseeb khiav torque tom qab kev teeb tsa yog qhov siab tshaj qhov xav tau, qhov ua rau yuav tsis yog ntau dhau preload ib leeg.
Tej yam ua tau muaj xws li:
Misalignment ntawm taag thiab floating kev txhawb nqa
Cov txiv ntseej mounting tsis raug
Foob tsis kam
Tsis txaus los yog tsis tsim nyog lubrication
Yuav tsum tau ua tiav qhov kev tshuaj ntsuam xyuas ua ntej hloov chaw preload.
Preload tsis tuaj yeem hloov cov qauv Rigidity thiab kev sib dhos kom raug
Pob ntsia hlau txiv ntseej rigidity tsuas yog ib feem ntawm kev ua tiav cov lus tsa suab.
Zuag qhia tag nrho system nruj kuj raug cuam tshuam los ntawm:
Kho -kawg bearings
Txiv ntseej vaj tse qauv
Tshuab rooj
Linear qhia system
Coupling rigidity
Tshuab ncej
Yog hais tias cov kev txhawb nqa bearing muaj kev tshem tawm ntau dhau los yog cov qauv ntsia hlau tsis muaj zog, kev ua ntej ua ntej tsuas yog tsim kom muaj cua sov ntxiv yam tsis muaj kev txhim kho qhov chaw ua haujlwm zoo.
Yuav ua li cas txiav txim seb puas yuav tsum tau preload
Thawj kauj ruam yog los txhais:
Tso cai rov qab yuam kev
Kev ua haujlwm tiag tiag
Tsab ntawv tsa suab
Qhov xav tau ntawm qhov chaw
Rau cov ntawv thov uas feem ntau yog ib qho - kev taw qhia kev thauj khoom, xws li:
Conveying systems
Vertical lifting axes
lub load sab nraud tuaj yeem tswj kev sib cuag hauv ib qho kev taw qhia, thiab xoom- kev ua haujlwm tshem tawm yuav tsis tsim nyog.
Rau cov ntawv thov muaj xws li:
Feem ntau bidirectional positioning
Contouring machining
Precision quab yuam tswj
preload yuav tsum tau ua tib zoo soj ntsuam.
Rau siab - nrawm, ntev - lub sijhawm ua haujlwm, tus tsim qauv yuav tsum sib npaug:
Rigidity
Qhov tseeb
Kub nce
Kev pab lub neej
Cov ntaub ntawv xav tau thaum xaj pob ntsia hlau
Rau kev xaiv kom raug, cov neeg siv khoom yuav tsum muab:
Qhov siab tshaj plaws thiab nruab nrab axial load
Kev khiav hauj lwm ceev
Kev nrawm
Tsab ntawv tsa suab
Positioning raug qhov yuav tsum tau
Repeatability yuav tsum tau
Tso cai kub nce
Txoj kev teeb tsa
Motor specifications
Yog xav tau ib chav preload tshwj xeeb, kuj muab:
Cov khoom siv tau tus qauv
Tus qauv naj npawb
Chaw tsim tshuaj paus preload specification
Cov tuam txhab sib txawv tuaj yeem siv cov kev faib ua ntej sib txawv, yog li cov qib yuav tsum tsis txhob muab piv ncaj qha yam tsis tau kuaj xyuas qhov tseeb.
Xaiv qhov raug Preload rau kev ntseeg siab Precision Motion
Lub hom phiaj ntawm preload yog ua kom txaus rigidity thiab txhim kho kev rov qab txav kev ua tau zoo - kom tsis txhob tsim lub siab tshaj plaws load sab hauv.
Ib qib xaiv preload kom raug muab qhov sib npaug zoo tshaj plaws ntawm:
Positioning raug
Mechanical efficiency
Kev ua haujlwm thermal
Ntev - lub neej ua haujlwm ntev
Tianjin OuNaiDamuab kev txhawb nqa rau kev xaiv pob ntsia hlau, suav nrog kev ntsuam xyuas ntawm:
Axial clearance xav tau
Preload xaiv
Ncej-end machining
Bearing kev them nyiaj yug configuration
Raws li cov khoom siv tiag tiag, Tianjin OuNaiDa pab cov neeg siv khoom txhim khu kev ntseeg tau thiab ua kom zoo tshaj qhov kev daws teeb meem.
