IKO outer spherical bearing of the troubleshooting methods of noise limit speed

Of course, in terms of monitoring and diagnosis of outer spherical bearing fault, using vibration than noise is much more easy and reliable, therefore, the vibration is the main research direction. But, it's not belong to the bearing itself, and belongs to the problem of bearing applications, should be a different matter. Owing to IKO bearing vibration and noise the direct correlation, under certain conditions can be said to be the synonym, so in the production and use, always will be 'anti-vibration noise reduction' together, 'low vibration bearing' tend to habitually called 'low noise bearings,' reasons for this. By controlling the IKO bearings to control bearing vibration noise, not only directly caught the source and the cause of the noise, also because of implementation is simple, such as measuring vibration less affected by environmental conditions, basic easily separation and easily applied in the actual production, etc. While measuring noise to the environment conditions the demand is higher, need to have a very low background noise, so generally must be in silencing indoor construction cost is higher. From spalling, indentation, rust, crack and wear will be reflected in the outer spherical bearing vibration measurement, bearing vibration of IKO bearing damage is very sensitive, so the bearing through the use of special bearing vibration meter ( Frequency analyzer, etc. ) Can measure the size of the vibration, through frequency points cannot deduce the abnormal situation. Due to the measured values of bearing or sensor installation position and different using conditions, thus requiring prior to each machine is analyzed by the measured value of the determined after judgment standard. Rotational speed of the IKO bearings are mainly affected by the IKO bearing the limitation of internal temperature rise caused by friction heat, when the speed exceeds a certain limit, the bearing will can't continue to rotate for burns, etc. Outer spherical bearing limit rotational speed is not burned to produce friction heat and the threshold of the continuous rotation. Therefore, IKO bearing limit speed depends on the type, size, and precision bearings and lubrication way, the quantity and quality of the lubricant, keep the frame material and a variety of factors such as type and load conditions. All kinds of bearing with grease lubrication and oil lubrication ( Oil bath lubrication) Limit rotational speed is respectively in each outer spherical bearing size table, the value standard design of the bearing under the condition of load when rotating speed limit values. In addition, the lubricant according to their kinds and brands, may also is superior to other performance but is not suitable for high speed rotation. In the process of using IKO bearings due to improper operation, inadequate lubrication, rust and corrosion, and some other factors such as current, external material, such as eccentric caused outside the spherical bearing service life. Therefore guangdong guangzhou yue in the process of using the bearing axis trading company is necessary to remind everyone of bearing precautions should have sufficient knowledge and understanding.
