We
all know that Jintai bearings in the operation of the time may be
issued some abnormal sound, such as raceway sound, rolling rolling
sound, ringing sound, cage sound and other sound. Today Jintai bearing agents for you to explain the following reasons for the sound and the solution. The following are the same as the "
First
of all, if the Jintai bearing run the raceway sound, we need to first
understand the Jintai bearing issued this sound is reasonable, after the
test proved Jintai bearings in the operation if the issue of 25 ~ 27dB
sound is a reasonable category. If you deviate from this value, it is necessary to consider whether the Jintai bearing's working surface is abnormal.
Solution: Correct use of Jintai bearings and accurate use of Jintai bearings to noise reduction. Followed by falling body rolling sound, this sound occurs under low speed and bear the radial load of large Jintai bearings. According
to the noise, we can effectively reduce the noise by using the preload
method, reduce the radial clearance of the Jintai bearing after
installation, and improve the use of good lubricants. Some foreign
companies use light rolling elements such as ceramic roller or hollow
roll And other technical measures to prevent the generation of such noise. If
you hear the sound of the ring is to consider whether there is
excessive friction between the parts, we must first consider whether the
installation problem caused. This
noise can be reduced by reducing the radial clearance of the Jintai
bearing and using a shallow outer ring raceway structure to prevent it. Finally,
if there is a cage sound, it is necessary to determine which parts of
the cage there is a problem, whether it is because Jintai bearing
friction vibration generated.
