Check the IKO rail bearing the details and daily maintenance methods of sound

Using the method of chemical additive bearing, adding a certain chemical additives in lubricating oil, can reduce the noise of railway bearing, such as tianjin, the same factory production of low noise grease additive noise, can reduce 3 from the basis.
9 the original bearing noise, 9.
2 db, suitable for micro and small bearings.
Absorber vibration isolation device in use or vibration isolation device, in order to reduce the noise, or noise isolation bearings IKO bearings, obtain good effect, but it usually paid a high price in the economy, sometimes larger institutions, the change of the thermal condition, or easy to rust, use should be thoughtful, and later, just take other measures, to achieve low noise also cannot be used in the future the goal of this method.
The simplest example is high speed, and not by railway bearings and thrust to the heart of the thrust bearing and thrust bearing shell ball bearing outer ring under suction plastic coat anti-rust lubricant, allowing usually cylindrical hole plastic insert, or in the same group, but can't control the rotation and the adjacent mechanical friction or interference.
This method has a certain role in the muffler.
Another example is in the middle of the seat between the bearing and add a hole, you can spread the vibration attenuation of bearing rotating system, but it needs to be deployed properly, or may have the opposite effect.
Changed the method of the corresponding parts of the host IKO bearing noise velocity is very sensitive to load, but the speed is very sensitive conditions permit, to reduce the speed, and increase the torque of the ways to achieve the same job, but it reduces the noise.
Pump system to reduce the noise, the original use of the motor speed was 1430 r/min under 10 l/min pump flow, the speed of 710 r/min and size larger pump and electric motor pump itself the same flow pump bearings, oil pump motor bearing noise is significantly reduced, but the entire group of an expanding footprint, cost is also increased.
Check railway bearing vibration value changes, the production of abnormal noise, temperature, the amount of lubricant and trait of change, drive the change of the mechanical and electrical current value, check whether the normal, if there is abnormal, it should be handled accordingly.
Below is the check project to control execution.
1.
Determine each inspection item of chart formats.
2.
To determine the inspection cycle.
3.
Determine the need inspection methods and inspection equipment.
Check and record data.
Then observe the changes of the graph data.
If the data is beyond the standard components, could be a sign of equipment damage.
Confirm the reasons of the problem, when need to repair.
