Spherical Cov Menyuam Bearings MB
Technical yam ntxwv
Spherical roller bearings muaj ob kab ntawm spherical rollers, lub nplhaib sab nraud muaj ib qho concave kheej kheej raceway, lub nplhaib puab muaj ob lub concave raceways uas yog inclined ntawm ib lub kaum sab xis rau cov kabmob axis, qhov chaw curvature ntawm lub nplhaib sab nrauv raceway yog zoo ib yam nrog cov bearing center. Spherical roller bearings yog tus kheej-aligning, tsis cuam tshuam los ntawm ncej thiab bearing box misalignment los yog ncej deformation deflection, tuaj yeem them nyiaj rau qhov ua yuam kev concentricity. Ntxiv nrog rau cov kabmob radial load, hom kabmob no tuaj yeem tiv taus ob txoj kev axial load thiab nws cov load ua ke, lub peev xwm loj dua, thiab tib lub sijhawm muaj kev tiv thaiv kev vibration zoo dua, cuam tshuam tsis kam.
Spherical roller bearings tuaj yeem raug kaw tsim, bearing ob sab nrog cov ntsaws ruaj ruaj. Lub nplhaib foob siv roj-resistant thiab hnav-resistant roj hmab.
Spherical roller bearings muaj 2, tus qauv (N), 3, 4 thiab 5 pawg ntawm kev tshem tawm sab hauv, tapered lub qhov kheej kheej cov menyuam bearings nrog 3 pawg clearance rau tus qauv clearance. Rau ntau dua los yog tsawg dua tus qauv tus nqi ntawm clearance bearings kuj yuav ua tau raws li cov neeg siv yuav tsum tau.
Vibrating machinery bearings yuav tsum siv qhov loj radial clearance, 3, 4 pawg los yog nyob rau hauv 3 mus rau 4 ntawm qhov tsis-tus qauv clearance.
Vibrating npo nrog spherical roller bearings rau 4 pawg ntawm kev tshem tawm.
Ib qho yooj yim installation:
Spherical roller bearings muaj cylindrical thiab tapered bore, tapered tapered bore taper 1:12 thiab 1:30 ob, tapered bore bearing nrog lub tes tsho nruj los yog lub tes tsho tshem tawm, tuaj yeem ua tau tapered bore kheej kheej cov menyuam bearing yooj yim, ceev sib dhos hauv lub teeb ncej lossis kauj ruam tshuab ncej.
