SKF bearings are generally manufactured through forging, heat treatment, turning, grinding and assembly of multi-channel processing operations. The reasonableness of the processing technology, advanced, will also affect the stability of the bearing life. Which affect the quality of the finished product bearing heat treatment and grinding processes, often associated with the failure of the bearing has a more direct relationship. In recent years, deterioration of the bearing surface layer of the study, the bearing surface of the grinding process and the quality of the close.
First, the shock effect of SKF bearings.
In normal use, the vibration of the bearing damage is very sensitive, peeling, creasing, corrosion, cracks, wear, etc. will be in bearing vibration measurement reflected. Therefore, through the use of special bearing vibration measurements (frequency analyzer, etc.) to measure the size of the vibration, the frequency points can not be inferred by abnormal circumstances. The measured values ​​due to the use of conditions or bearing sensor installation location is different, so each machine needs prior to the analysis and comparison of the measured values ​​determined criteria.
SKF bearings for vibration damage can be quite sensitive, peeling, creasing, corrosion, cracks, wear, etc. will be in bearing vibration measurement reflected. Therefore, through the use of special bearing vibration measurements (frequency analyzer, etc.) to measure the size of the vibration, the frequency points can not be inferred by abnormal circumstances. The measured values ​​due to the use of conditions or bearing sensor installation location is different, so each machine needs prior to the analysis and comparison of the measured values ​​determined criteria.
Second, the impact of temperature on the bearing.
High-temperature bearings SKF has often said that in unusual circumstances. Temperature is harmful to the bearing lubricant. Sometimes can be attributed to the bearing overheated bearing lubricant. If the bearing temperature over 125 ℃ even move to reduce long-term bearing life. Caused by high bearing the following reasons: lack of lubrication or over lubrication, lubricant. Contains impurities, the load is too large, the bearing ring damage, lack of space, and produce high-friction seals and so on.
Therefore, continuous monitoring of temperature of SKF bearings is necessary, whether it is measuring the bearing itself or other important parts. If you are under the same operating conditions, the temperature change can be said that any failure has occurred.
SKF Bearing temperature can be measured by means of a regular thermometer, such as digital thermometers, bearing temperature can be accurately measured and determined by ℃ or Fahrenheit temperature display unit. The importance of bearing, which means that when it is damaged, can cause equipment downtime, so the best type of bearing temperature detectors should be installed.
