INA Bearing produces noise in operation, including scar noise and dust noise. How to solve the noise Ina Thrust Ball Bearing generated by thrust ball bearing in operation?
It is mainly to find the causes of noise first, and then take different methods to reduce the bearing noise according to different Ina Thrust Ball Bearing reasons. Causes and solutions of the following bearing noise during operation:
(1) Scar sound and its control method
If there is crack, indentation or corrosion on the rolling surface of rolling bearing, periodic vibration and noise like riveting rivets will occur. Its cycle may be fixed and most of it has a certain corresponding relationship with the rotating speed.
The scars will occur continuously Ina Thrust Ball Bearing on the channel, and the scars will appear on the steel ball from time to time, and this noise will change with the installation and lubrication conditions.
The control methods of this kind of noise include: do not knock the thrust ball bearing during installation, and prevent the bearing from being installed obliquely when the bearing is assembled with the shaft and then installed into the bearing seat;
Prevent ina bearing from rusting Ina Thrust Ball Bearing during storage and shock vibration during transportation; Use grease with high viscosity
(2) Dust sound and its control method
If there are dust and other foreign matters in the rolling bearing, aperiodic vibration and so-called dust sound will occur. The Ina Thrust Ball Bearing magnitude of vibration and noise is uncertain, and there may or may not be.
improving the cleaning method of INA Bearing, and strictly cleaning the thrust ball bearing, shaft, seat hole and matching parts before Ina Thrust Ball Bearing installation; Remove foreign matters in the lubricant; Improve the sealing of bearings; Avoid using plastic cages with impure materials or embedded foreign matters.
(3) Noise caused by lubrication factors and Its Countermeasures
Incorrect lubricant selection, insufficient lubricant or aging hardening can lead to vibration and noise of thrust ball bearing, and this noise has no certain law. In this case, only select the appropriate lubricant, adjust the amount of lubricant, prolong the service life of lubricant and reasonably determine the replacement cycle.
Improper lubrication accounts for 36% of the causes of premature bearing failure The general grease can not meet the needs of various special ina bearing applications. Using only one or all kinds of general grease to meet all thrust ball bearing applications will cause problems far exceeding the benefits of a unified brand.
The application conditions of Ina Thrust Ball Bearing bearings are very diverse. Correct lubrication requires that the grease match the application conditions of bearings.
Bearing grease is the basis for ensuring smooth, worry free operation and high reliability of bearings, even under extreme Ina Thrust Ball Bearing working conditions. Grease can prevent contaminants from entering ina bearings, buffer impact load and prevent corrosion.
In practical application, the selection of appropriate grease is the basic condition for obtaining long service life of thrust ball bearing
The criteria for the correct selection of lubricants include the type and size, temperature, speed, load, expected service life and supplementary lubrication cycle of thrust ball bearings.
