It is not a good thing that the vibration of Slewing Support occurs in the process of using. So what causes the bearing vibration? For experienced people, it can be seen at a glance, but for novices, it may not be seen after half a day's observation. Today we have invited relevant experts to introduce and analyze the main factors of slewing bearing vibration for you.
It may be due to the radial clearance. Too large or too small radial clearance will cause large vibration of the system. If the radial clearance is too small, it will cause high-frequency vibration, and if the radial clearance is too large, it will cause low-frequency vibration. The test results show that the radial clearance is too large to reduce the radial natural frequency of the elastic system. It is easy to produce resonance and large low frequency vibration. This is because the impact point of the rollers and rings will produce greater acceleration. In the initial stage of impact, high frequency compression waves independent of mechanical mass and shape of the object are generated and propagated into the metal. In the later period of shock, a mechanical vibration with lower frequency than shock compression wave will be produced by mechanical force. Therefore, the radial clearance will increase the vibration in the passband.
In fact, there are other factors besides the factors mentioned above which may cause the vibration of slewing support. We can consult our technical engineer in time if there are any problems in use.
