For slewing support, after using for a period of time, there will inevitably be some problems, such as noise problems in the operation of slewing support, which greatly affects the normal use of slewing support, and if not solved in time, it may also affect the service life of slewing support. So, in this case, what causes the noise of slewing bearing? Let's have a look.
Generally speaking, cracks, indentations or rusts on the rolling surface of slewing bearings are caused by some noises. Of course, sometimes the noises are also related to poor lubrication.
In this regard, we need to adopt reasonable control methods, such as:
Installation of bearings can not be knocked, the bearing and shaft assembly and then loaded into the bearing seat to prevent bearing inclination;
Use grease with high viscosity.
If there are cracks, indentations or rusts on the rolling surface of slewing bearing, periodic vibration and noise like riveting rivets will occur. The control method of this kind of noise:
Scars will occur continuously in the channel, and the scars will appear on the steel balls from time to time, and the noise will change with the installation and lubrication conditions. Its period may be fixed, but it mostly corresponds to the rotational speed. With high viscosity grease, the bearing can not be knocked during installation, the bearing can be prevented from rusting in stock and shock vibration during transportation, and the bearing can be prevented from inclining when the bearing and shaft are assembled and then loaded into the bearing seat.
In view of the different causes of noise generated by slewing bearings, we can adopt different methods to deal with and solve them, so as to ensure the normal use of slewing bearings.
