Rolling or sliding nsk bearing assembly into one
Most favorable price : sales@hellerbearings.com
The machine shaft, especially the spindle, Rolling or sliding NSK Bearings in general are assembled into one, and rotating at high speed, sometimes it will produce a high heat. This phenomenon, if not immediately removed, will lead to bearing overheating, and the corresponding parts of the machine temperature and thermal deformation, in severe cases make the spindle and the tailstock is not high, which affects not only the machine itself precision and accuracy of processing, but will burn out the bearings. The spindle bearing the heat of the reasons for its exclusion as shown in Table I.
The scroll FAG Bearings fever and its Remedy
(1) the reasons for low accuracy: bearing
Methods: specified levels of precision NTN bearings.
(2) reasons: the spindle bent or Holes heart
: Fix the spindle or box.
(3) reasons: belt tight
Method: Adjust the belt so that elastic appropriate.
(4) reasons: poor lubrication
Method: INA Bearing the selection of the required grades of lubricating materials and properly cleaned.
(5) reasons: the low quality of assembly
Methods: improve the quality of assembly.
(6) Reason: the bearing shell laps
: Replace imports bearings and wear parts.
Axial force is too large (7)
Methods: washing, adjusted to seal the mouth ring clearance requirements between 0.2 ~ 0.3mm, the correct impeller balance hole diameter and calibration of static equilibrium value.
(8) bearing damage
Methods: replacement of bearings.
