Slewing ring is a large bearing that can bear comprehensive load. It can bear large axial, radial load and overturning moment at the same time. Once a problem occurs, it will make a variety of noises. How can we solve these noises? The rotary table bearing manufacturer takes you to explore.


1. Control method of scar sound


If there is crack, indentation or corrosion on the rolling surface of the slewing ring, periodic vibration and noise like riveting rivets will occur. The cycle may be fixed, but most of them have a certain corresponding relationship with the rotating speed. The scars will occur continuously on the channel, and the scars will appear and disappear on the steel ball, and this noise will change with the installation and lubrication conditions.


Control method of this kind of noise: do not knock the bearing during installation. When the bearing is assembled with the shaft and then installed into the bearing seat, prevent the bearing from being installed obliquely; Prevent bearing corrosion during storage and impact vibration during transportation; Use grease with high viscosity.


2. Noise caused by lubrication factors and Its Countermeasures


Incorrect lubricant selection, insufficient lubricant or aging and hardening can lead to vibration and noise of slewing ring / rotary table bearing, and this noise has no certain law. In this case, only the appropriate lubricant can be selected, the lubricant amount can be adjusted, the service life of the lubricant can be prolonged and the replacement cycle can be reasonably determined.


3. Control method of dust sound


If there are dust and other foreign matters in the rotary support, aperiodic vibration will occur. The so-called dust sound, the magnitude of vibration and noise is uncertain, with or without.


Control method of dust noise: improve the cleaning method of slewing ring / rotary table bearing, and strictly clean the bearing, shaft, seat hole and matching parts before installation; Remove foreign matters in the lubricant; Improve the sealing of bearings; Avoid using plastic cages with impure materials or embedded foreign matters.
