Cov ntsiab lus
tsis muaj menyuam bearing
Dab tsi yog cov menyuam bearing?
Cov menyuam bearings yog cov kabmob uas siv cylindrical, tapered, lossis spherical rollers li dov cov ntsiab lus. Tsis zoo li "point contact" ntawm pob bearings, tus tsim ntawm cov menyuam bearings yog raws li lub hauv paus ntsiab lus ntawm "kab contact" los yog "hloov kab sib cuag."
Qhov sib txawv tseem ceeb no tso cai rau lawv tuaj yeem tiv taus ntau dua radial lossis axial loads dua li pob bearings ntawm tib qhov loj, tab sis feem ntau ntawm cov nqi ntawm kev txwv ceev.
Txoj Cai Ua Haujlwm
Functionality Yog vim li cas cov menyuam bearings tuaj yeem txhawb nqa kev thauj khoom ntau dua thiab kev ua haujlwm siab dua yog tias thaj chaw tiv tauj tsis yog ib qho taw tes tab sis yog hloov txoj kab (lossis nto). Qhov no txhais tau hais tias kev sib cuag kev ntxhov siab yog qis dua thiab kev txhawb nqa ntau dua. Qhov no kuj nce qhov poob siab tsis kam thiab txo qhov kev ua tau zoo tag nrho. Muaj ntau hom kev thauj khoom (ntshiab radial, axial, tus kheej- kev sib dhos muaj peev xwm, thiab lwm yam). Txhawm rau ua kom haum li ntawd, cov khoom siv dov tuaj yeem siv tau, suav nrog tapered, cylinder, thiab kheej kheej.
Cov yam ntxwv tseem ceeb
Cov yam ntxwv tseem ceeb Loj Load Capacity: Vim muaj kab sib cuag, qhov no muaj peev xwm ua tau siab radial lossis axial load. Kev tiv thaiv zoo rau kev poob siab thiab kev vibration: Cov kab kev sib cuag thiab cov qauv tsim ua rau muaj txiaj ntsig zoo rau kev tuav, poob siab, thiab kev co. High Rigidity: Cov txheej txheem nrog ntau dua deformation / so kom txaus siab tag nrho rigidity nrog load heev. Qeb Tsawg: Cov huab hwm coj ntau dua thiab kev sib txhuam los ntawm cov chais ua rau cov kev txwv ceev tau qis dua piv rau lub pob ntawm qhov sib npaug ntawm cov kabmob loj. Ntau yam ntawm Cov Qauv: Ntau qhov kev tsim qauv sib txawv pab txhawm rau ua kom zoo rau cov ntshiab radial, ntshiab axial lossis sib xyaw ntawm radial thiab axial loads.
Hom loj
Cylindrical Cov Menyuam Bearing: Yam ntxwv: Cov kabmob no muaj cov kabmob cylindrical thiab tau pib tsim los tswj cov kabmob radial siab heev thaum muaj peev xwm tsis tshua muaj peev xwm rau axial loads. Muaj nyob rau hauv ib qho - kab thiab ob - kab kev npaj. Qee tus muaj me me axial quab yuam tsis kam thiab muaj tav los tswj cov chais. Daim ntaub ntawv: Feem ntau siv nyob rau hauv gearboxes, loj fais motors, thiab zeb yob caj dab. Tapered Cov Menyuam Bearing: Yam ntxwv: Cov menyuam yaus muaj qhov zoo li qhov tsis txaus ntseeg. Lawv muaj peev xwm tiv taus qhov loj radial loads thiab unidirectional axial loads. Cov menyuam sib dhos nrog cov nplhaib sab hauv thiab sab nraud yog sib cais kom tso cai yooj yim installation thiab hloov ntawm kev tshem tawm. Lawv feem ntau yog siv ua khub los tiv thaiv bidirectional axial loads. Daim ntaub ntawv: Cov kabmob no yog siv rau hauv lub tsheb log hubs, gearboxes, siv tshuab, thiab hnyav{10}}lub luag haujlwm tsheb axles. Spherical Roller Bearing: Yam ntxwv: Cov kabmob no muaj lub thoob - zoo li cov menyuam yaus nrog rau lub nplhaib kheej kheej kheej kheej. Nws yog tus kheej-aligning thiab muaj peev xwm tiv taus siab heev radial loads, nruab nrab axial loads nyob rau hauv ob qho tib si kev taw qhia, raws li zoo raws li tseem ceeb ncej deflection. Daim ntaub ntawv: Cov menyuam bearings no yog siv rau hauv vibrating machinery, paper machinery, thiab ntev kis shafts. Koob Cov Menyuam Bearing: Yam ntxwv: Cov kabmob no muaj qhov ntev, nyias cylindrical rollers uas hu ua koob. Cov kabmob muaj qhov me me radial cross-section, tab sis siab radial load peev. Nws yog qhov tshwj xeeb uas nws tsis tuaj yeem tiv taus axial loads. Daim ntaub ntawv: Cov kabmob no yog siv hauv cov qauv tsim xws li kev sib kis ntawm tsheb thiab kev sib txuas ntawm cov tshuab. Thrust Cov Menyuam BearingTrait: Kev cai ua los tiv thaiv cov axial loj thiab tsis tuaj yeem tuav cov radial loads. Qhov no suav nrog thrust cylindrical roller bearings, thrust tapered menyuam bearings, thiab thrust spherical roller bearings. Siv: ntsug hydraulic turbines, loj crane slewing rings, txhaj tshuaj molding tshuab.
Pros thiab Cons
Qhov zoo

High rigidity thiab me ntsis deformation thaum nyob rau hauv load.
Zoo misalignment muaj peev xwm. Zoo misalignment muaj peev xwm yog qhov zoo thiab tshwj xeeb rau spherical roller bearings.
Qee hom yuav muaj kev kho kom haum. Ib qho piv txwv suav nrog qee cov tapered roller bearings.
Qhov tsis zoo
Pob bearings feem ntau muaj kev txwv ntau dua.
Kub nce thiab kev sib txhuam yog qhov siab.
Kev txhim kho thiab lubrication yuav tsum zoo thiab raug.
Feem ntau hom yuav tsis tiv nrog siab radial thiab siab axial loads nyob rau tib lub sij hawm, nrog bulged kev zam, piv txwv li tapered roller bearings.
Lub suab nrov yog feem ntau siab dua pob bearings, tshwj xeeb tshaj yog thaum ua haujlwm.
Cov cheeb tsam tseem ceeb ntawm daim ntawv thov
Cov menyuam bearings yog ib qho yuav tsum muaj nyob rau hauv kev lag luam hnyav, cov khoom siv hnyav thiab kev ua haujlwm hnyav heev.StRong daim ntawv thov yog nyob rau hauv steel dov mills, mining, loj gearboxes. Cov tsheb hnyav muaj xws li lub log, hubs thiab kis tau tus mob. Cua turbines thiab loj hydraulic generators kuj muaj peev xwm ua haujlwm siab. 'Kev thauj cov thoob loj elevator thiab conveyors kuj yog ib qho yuav tsum tau ua. Spherical roller bearings feem ntau yog siv hauv vibrating cov ntxaij vab tshaus thiab feeders. Hnyav aerospace Cheebtsam muaj xws li tsaws iav thiab helicopter rotor systems.
Xaus
Thaum cov ntsiab lus tseem ceeb ntawm daim ntawv thov yog lub peev xwm thauj khoom, kev poob siab, thiab kev nruj, tsis yog kev txwv ceev, cov menyuam bearings yog qhov kev xaiv tsis muaj teeb meem. Nws ua lub luag haujlwm tsis tuaj yeem hloov pauv hauv cov tshuab hnyav thiab hnyav ib puag ncig, muab kev txhawb nqa zoo rau cov pob txha ntawm kev lag luam.
