Sliding
bearing a rotation, the inner ring and the outer ring of the raceway
surface and the rolling body is rolling contact bearing and thus the
trajectory is dark, the trajectory attached to the raceway surface does
not belong to the exception This variable load conditions can be learned
so When removing the bearing, please observe and observe the running track of the raceway surface. If you carefully observe the trajectory of the operation, then SKF
bearings will know that only bear the radial load to withstand large
axial load to withstand the moment load or in the bearing box has
extreme rigidity and so on.
You can check whether the sliding bearing with the accident load and
installation error is the country and so on and become the cause of the
cause of SKF bearings damage clues.
If
there is no choice of errors and the correct use of the words before
the bearing life, but with a long period of time in this case the damage
state for the stripping. On
the other hand there are unexpected early damage and can not withstand
the use of early damage as the cause of the early damage to the use and
lubrication of the consideration is not enough and then foreign body
intrusion sliding bearing assembly error and shaft deflection, the shaft
and bearing Box research is not enough and so on.
(1) the use of chemical additives method
Adding
certain chemical additives to lubricants in sliding bearings can reduce
SKF bearing noise. For example, a factory in Tianjin produces a low
noise grease containing noise reduction additives to reduce bearing
noise from the original basis by 3.9 to 9.2 dB. Used in miniature or small bearings.
(2) the use of vibration or vibration isolation device
The
use of vibration or vibration isolation device to reduce the noise of
sliding bearing or isolation bearing noise can be a good effect but it
is often in the economy to pay a lot of costs sometimes make the body
bigger cooling conditions or easy to use when the corrosion should be
fully considered only in other measures This method is used only after it has been able to achieve low noise.
