Ib qho txiaj ntsig tseem ceeb ntawm cov koob no yog nws tsim-hauv tus kheej- ua kom haum. Lub nkhaus profile ntawm cov chais, ua ke nrog lub rooj zaum kheej kheej ntawm lub tsev ntxhua khaub ncaws, cia li ua kom haum me me angular yuam kev ntawm lub ncej thiab lub tsev. Qhov no txo cov kev ntxhov siab los ntawm kev txhim kho misalignment, ncej dabtsi yog khoov, los yog thermal expansion, pab tswj kom txawm load faib thoob plaws cov menyuam txheej. Cov bearings no ua tau zoo tshwj xeeb tshaj yog nyob rau hauv qis mus rau nruab nrab speeds qhov twg zoo meej alignment yog nyuaj tab sis muaj zog axial rigidity yog qhov tseem ceeb.
Cov txiaj ntsig ua haujlwm tseem ceeb
Kov High Axial Loads
Lub spherical rollers yog tsim los nqa cov thrust loads nyob rau hauv ib qho kev taw qhia. Qhov no ua rau cov kabmob haum rau cov tshuab hnyav uas axial quab yuam yog ib feem tseem ceeb ntawm kev ua haujlwm load.
Tso cai txwv tsis raug cai
Txoj kev sib tw kheej kheej tuaj yeem ua raws li qhov tsis sib xws ntawm cov ncej thiab vaj tse. Qhov no tuaj yeem muaj txiaj ntsig zoo hauv cov khoom siv qhov twg ncej deflection lossis mounting deviation tsis tuaj yeem zam tag nrho.
Tswv yim rau cov cuab yeej hnyav
Cov kabmob yog npaj rau kev thov kev lag luam kev lag luam es tsis yog lub teeb - cov khoom siv ua haujlwm. Kev tsim nyog lubrication, mounting thiab load tej yam kev mob yog ib qho tseem ceeb rau kev tswj ib txwm bearing kev ua tau zoo.
Separable Cheebtsam
Lub tshuab ntxhua khaub ncaws, lub tshuab ntxhua khaub ncaws thiab cov menyuam-cage tuaj yeem sib cais. Rau cov kabmob loj dua, qhov kev tsim kho no tuaj yeem ua rau kev teeb tsa thiab kev saib xyuas yooj yim dua.
Kev them nyiaj yug ruaj Axial
Cov kabmob muab kev txhawb nqa ncaj qha rau axial rog thiab tuaj yeem siv qhov chaw tswj axial xav tau.
Technical Specifications
ZWZ ib qho kev taw qhia thrust spherical cov menyuam bearings yog tsim raws li lub teb chaws thiab thoob ntiaj teb cov qauv:
● Cov qauvGB / T 307.4 thiab ISO 104, nrog rau cov chav kawm kam rau ua nrog rau P0 (tus qauv), P6, P5, thiab P4 rau cov ntawv thov raug.
● Qhov Loj Loj: bore diameters los ntawm 60 mm mus rau 1500 mm, npog feem ntau hnyav kev siv.
Cage Materials:
● Brass machined tawb: txheem rau nruab nrab - loj bearings (sab nraud txoj kab uas hla Tsawg dua los yog sib npaug li 500 mm)
● Steel khoom tawb: siv rau cov bearings loj (sab nraud txoj kab uas hla> 500 mm) rau kev txhim kho lub zog
Load Rating:
● Sib npaug dynamic load: P=Fa
● Sib npaug zoo li qub load: P₀=Fa
