Of course, in terms of SKF bearings fault monitoring and diagnosis using vibration much easier to implement and much more reliable than the noise, therefore, is undoubtedly the main research directions of vibration. However, this is not part of the problem with the bearing itself, is a cylindrical roller bearing applications issue, should be a different story.
Because of the SKF bearing this direct relationship between vibration and noise, under certain conditions, can be said to be synonymous, in production and use, always "reduce vibration and noise," together, "low-oscillation bearings" are often used to call it "low noise bearings", why is this.
Control by controlling vibration of cylindrical roller bearing noise, not only captures the sources and causes of noise, due to the relatively simple to implement, such as measuring less affected by environmental conditions, vibration isolation, makes it easier to produce the actual underlying vibration is easy to apply. Measurement noise the demanding environmental conditions, needs to have a very low background noise, so generally in anechoic room of high construction costs.
Indentation cracks, wear, corrosion, spalling, are reflected in the measurement of vibration of cylindrical roller bearings and bearing vibration of bearing damage is very sensitive, so by using a special bearing SKF bearing vibration Measurer (frequency Analyzer, etc) measures the size of the vibration, through frequency not infer exceptions to the specific situation. Because of the measured values from bearing conditions of use or the sensor installation locations and different, therefore require prior to each machine analysis and comparison of measurement values to be determined benchmarks.
Bearing vibration are sensitive to SKF bearing failures, such as the indentation cracks, wear, corrosion, spalling, are reflected in the measurement of vibration of deep groove ball bearings, therefore, through the use of special bearing vibration Measurer (frequency Analyzer, etc) measures the size of the vibration, through frequency not infer exceptions to the specific situation. Measured values from bearing conditions of use or the sensor installation location is different and therefore require prior to each machine analysis and comparison of measurement values to be determined criteria.
Using heat sensors can monitor cylindrical roller bearing temperature and temperature alarm when exceeding a specified value or stop to prevent burning shaft accident.
High temperatures are often said to be in unusual circumstances. High temperatures may also be harmful to SKF bearing lubricant. Sometimes overheating could be attributed to cylindrical roller bearings with lubricant. Bearing temperature in more than 125 ° c long-term continuous transfers reduce the bearing life. Cause of the high temperature bearings including: inadequate or excessive lubrication lubrication, lubricant. Contains impurities, excessive load, rings of bearing damage, inadequate clearance, and oil have high friction and so on.
SKF bearing temperature monitoring is necessary for continuity, both bearing itself or other important parts of the measure. If operating conditions do not change case, any temperature changes may have occurred at fault. In the actual production, machinery and equipment used by the fixed length of cylindrical roller bearing life directly related to normal use of the machinery and equipment for their production work. Although depending on the use environment and conditions of bearing selection, but has a lot of bearing on the far reaches the design life is damaged and fail. Failure of cylindrical roller bearing used in production which will produce intense vibration and noise, as well as the relevant parts are damaged, and finally cause a range of adverse effects.
