The use of chemical additives, SKF bearings, add a certain amount of chemical additives in the lubricant can reduce bearing noise, such as Tianjin, with a factory production of low-noise grease additive noise, can reduce the noise of bearings on the basis of 9.2 db, suitable for miniature and small bearings.
Absorber or vibration isolation devices to the use of inhaled or vibration isolation devices to reduce the noise, or isolation bearings SKF bearing noise, and achieved good results, but it is often paid a high price in the economy, sometimes larger institutions, the change of thermal conditions , or rust easily, use should be thoughtful, and before taking other measures to achieve the goal of low noise can not later use the method. The simplest example is a high-speed, instead of SKF bearings and thrust to the heart of the thrust bearing or thrust bearing shell to withstand ball bearings in the outer plastic suction coat anti-rust lubricant, allowing the general cylindrical bore plastic insert, or in the same group, but can not control the rotation and adjacent to the mechanical friction or interference. This approach has a certain role in the silencer. Another example is to set up a hole in the bearing between the seat and the middle add, you can spread the attenuation of the vibration force of the bearing seat rotation system, but it needs to deploy properly, or is likely to have the opposite effect.
Change the speed of the host SKF bearing the corresponding parts of the noise is not very sensitive to load, but the speed is very sensitive to the conditions allow, reduce speed and increase torque to achieve the same purpose, but it reduces the noise. To reduce the noise pump system, the original use of the motor speed is 1430r/min under the flow of 10L/min pump, speed 710r/min motor and larger pump and after pump the same flow pump bearings, oil pump motor bearing noise significantly reduced, but continue to expand the footprint of the entire organization, the cost has also increased.
Check the SKF bearing vibration value changes, the abnormal noise, temperature, amount of lubricant and characters change, drive an electromechanical current changes, check for normal, if there are abnormal, it should be handled accordingly.
Here is the implementation of the inspection items tend to control.
(1) determine the format of the chart of each check.
(2) to determine the inspection cycle.
(3) determine the inspection methods and inspection of equipment needed. Check and record data. Observe the chart data changes.
If the data exceeds the standard control value, may be signs of equipment damage. Confirm the cause of the problem, and repair when necessary.
