Choose bearing types-3

Date:2012-01-31 From:未知 Hit:

  It is very important to comprehensive grasp of the bearing using conditions when choose a suitable bearing.

  5. Bearing rigidity
  Satisfy the mechanical axis rigid requirement bearing types. In the spindle and at the end of the car slow down device level place, we should improve the shaft rigidity, and at the same time, we should improve the bearing rigidity.
  Roller bearing load lead to deformation is smaller than ball bearing. Applied to bearing preloaded (negative clearance) can improve the rigidity and this method is suit for angle contact ball bearing and tapered roller bearings.

  6. The relative tilt of bearings inner ring and outer ring.
  Analysis the relative tilt factors of bearings inner circle and the outer circle (such as the torsion of shaft caused by load, shaft and shell bad precision or installation error), and choose the bearing type can adapt to the using condition. If the inner ring and outer ring of relative tilt is too large, bearing will damaged by internal load. So  we should choose the bearing type can bear the tilt.
  Generally speaking, allowing the dip angle (or the heart Angle) increasing in the following order: cylindrical roller bearing, tapered roller bearing and deep groove ball bearings, angular contact ball bearing, spherical roller bearing.
