Dab tsi yog angular contact bearing?
Angular contact pob bearings yog dov bearings uas tuaj yeem tiv taus radial thiab axial loads ib txhij. Lub npe "angular contact" los ntawm nws cov qauv tsim: muaj lub kaum sab xis ntawm cov kabmob sib tw thiab lub pob (dov lub caij).
Kev sib cuag lub kaum sab xis: Lub kaum sab xis ntawm txoj kab txuas qhov chaw sib cuag ntawm lub nplhaib bearing thiab lub pob steel thiab lub dav hlau radial ntawm cov kabmob. Lub kaum sab xis no yog qhov tseem ceeb rau cov kabmob kom tiv taus axial loads.
Kev sib cuag lub kaum sab xis: 15℃(code C), 25℃(code AC), 30℃(code A), thiab 40℃(code B). Qhov loj dua lub kaum sab xis, qhov muaj peev xwm tiv taus axial loads.
Txoj Cai Ua Haujlwm
Thaum axial quab yuam ua rau ntawm cov kabmob, qhov kev sib cuag ntawm lub kaum sab xis decomposes lub zog no rau hauv radial thiab axial Cheebtsam, tso cai rau cov kabmob tuaj yeem tiv thaiv cov kabmob hauv ob qho tib si, uas tuaj yeem suav tias yog kev sib xyaw ua haujlwm ntawm qhov sib sib zog nqus groove pob bearings thiab thrust pob bearings.
Cov yam ntxwv tseem ceeb
Muaj peev xwm withstanding ua ke loads: muaj peev xwm tiv tau ob qho tib si radial thiab unidirectional axial rog ib txhij. Qhov no yog nws tus yam ntxwv tseem ceeb tshaj plaws.
Kev muaj peev xwm ceev: Vim yog siv cov khoom siv dov, lawv qhov ceev tshaj plaws yog feem ntau siab dua li cov menyuam bearings.
High rigidity: Los ntawm preloading, sab hauv clearance yuav raug tshem tawm, lub rigidity ntawm lub bearing system yuav tsum tau txhim kho, thiab deformation nyob rau hauv load yuav txo tau.
Kev sib hloov tau siab: Ua tsaug rau cov cuab yeej ua ntej tensioning, angular contact bearings tuaj yeem muab cov kev taw qhia axial meej heev, ua rau lawv siv dav hauv siab - daim ntawv thov precision.
Feem ntau siv ua khub: ib qho kev sib tiv tauj ib leeg tuaj yeem tiv taus axial quab yuam hauv ib qho kev coj. Txhawm rau txhim kho txoj haujlwm bidirectional ntawm tus ncej thiab tiv thaiv bidirectional axial rog, lawv feem ntau yuav tsum tau muab ntsia ua khub.
Main Installation thiab Configuration Methods
Vim lub fact tias ib tug angular contact bearing tsuas tuaj yeem tiv taus unidirectional axial quab yuam, hauv kev siv tswv yim, lawv feem ntau yog ua khub thiab siv raws li hauv qab no:
Rov qab-rau- rov qab teeb tsa
Yam ntxwv: Lub ntsej muag dav kawg ntawm ob lub bearings tau teeb tsa txheeb ze rau ib leeg.
Qhov zoo: Muab lub sijhawm nruj dua thiab tuaj yeem tiv thaiv lub sijhawm dhau los. Lub bearing siab kab yog divergent, muab zoo stability.
Daim ntawv thov: Haum rau cov ntawv thov uas yuav tsum tau muaj zog rigidity thiab tsis kam mus rau complex torques, xws li tshuab cuab tam spindles, gearboxes, thiab lwm yam.
Face to face configuration
Yam ntxwv: Lub ntsej muag nqaim kawg ntawm ob lub bearings raug ntsia txheeb ze rau ib leeg.
Qhov zoo: Cov kab siab ntawm cov kabmob converges. Lub thermal elongation thiab installation yuam kev ntawm lub ncej tsis zoo li rov qab - rau - rov qab configurations, thiab lub hauv paus muaj peev xwm yog me ntsis zoo dua.
Daim ntawv thov: Haum rau cov xwm txheej uas cov ncej thermal elongation lossis me ntsis tsis zoo nruab nrab yuav tshwm sim.
Serial configuration
Yam ntxwv: Ob lub bearings yog ntsia tau rau hauv tib qho kev taw qhia.
Qhov zoo: tuaj yeem nqa axial loads los ntawm tib qho kev taw qhia, txhim kho lub peev xwm axial hauv ib qho kev taw qhia.
Daim ntaub ntawv: Haum rau cov khoom loj los ntawm unidirectional axial rog. Nco ntsoov tias thim rov qab axial rog tuaj yeem ua rau cov kev teeb tsa tau yooj yim, yog li siv cov kabmob thib peb los muab kev txhawb nqa rov qab tuaj yeem ua haujlwm tau zoo.
Pros thiab Cons
Qhov zoo:
Nws muaj ob qho tib si radial thiab axial load-cov kabmob muaj peev xwm.
Kev kub ceev, kev sib txhuam qis.
High rigidity thiab precision tuaj yeem ua tiav los ntawm kev nruj ua ntej.
Kev ua haujlwm du nrog lub suab qis.
Qhov tsis zoo:
Feem ntau yuav tsum tau siv ua ke, uas ua rau tus nqi nce thiab kev teeb tsa nyuaj.
rhiab heev rau installation yuam kev (xws li misalignment).
Tsuas tuaj yeem tiv taus unidirectional axial quab yuam (ib leeg kabmob).
Kev tsim khoom thiab kev kho (pre tightening) yog qhov nyuaj tshaj li qhov sib sib zog nqus groove pob bearings.
Cov cheeb tsam tseem ceeb ntawm daim ntawv thov
Angular contact bearings yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas xav tau kev kub ceev, siab precision, thiab siab rigidit
1.Automotive sector: log hubs, sib txawv, turbochargers, thiab gearboxes.
2.Machine cuab tam spindles: cov kev siv ib txwm muaj xws li spindle systems ntawm lathes, milling tshuab, thiab machining chaw.
3.Aerospace: cov khoom tseem ceeb xws li cov cav thiab lub dav hlau kis tau tus mob.
4.Robotics: pob qij txha thiab txo qhov chaw ntawm cov neeg hlau.
5.Gear kis tau tus mob.
6.Motors thiab twj: xws li centrifugal twj thiab siab -ceev motors.
Xaus
Angular contact bearings feem ntau qhia tau hais tias muaj kev ua tau zoo thaum lub sij hawm siab - kev sib hloov ceev thiab thaum muaj ntau yam axial quab yuam. Tib lub sijhawm, lawv muab qhov sib npaug ntawm qhov tseeb, nrawm, thiab thauj khoom- nqa peev xwm. Thaum cov ntawv thov muaj cov kev xav tau no, angular contact bearings yog qhov kev xaiv zoo tshaj plaws.
