I. The oscillation of the INA bearing INA bearing oscillation is very sensitive to the damage of the bearing; for example, shedding, indentation, rust, crack, wear, etc. will be reflected in the INA bearing oscillation measurement; therefore; after the selection of the special bearing oscillation measuring device (frequency Analyzers, etc. can measure the large oscillations. ü De Shi Zhi 豢 豢 鲆 鲆 鲆 5 5 5 5 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 INA INA INA INA INA INA INA INA The measurement value of each machine is analyzed and compared to determine the specification.
Second, the temperature of the INA bearing temperature INA bearing; usually the temperature outside the bearing can be estimated; if the oil hole can directly measure the INA bearing outer ring temperature; it is more suitable.
Prof. Prof: The temperature of the INA bearing gradually rises with the start of the bearing; the steady temperature is reached after 1-2 hours. The normal temperature of the INA bearing is different due to the heat capacity of the machine; the heat dissipation; the speed and load are different. If it is smooth, the device is suitable; Then the bearing temperature will rise sharply; abnormal high temperature will occur; it is necessary to stop the work; take necessary precautions.
The thermal sensor can be used to monitor the working temperature of the INA bearing at any time; and when the temperature exceeds the specified value, the alarm is automatically activated or suspended to avoid the ignition of the shaft.
The high temperature often indicates that it is in an abnormal condition. The high temperature is also harmful to the smoothing agent of the INA bearing. Sometimes the INA bearing overheating can be attributed to the smoothing agent of the bearing. If the INA bearing rotates beyond 125 °C for a long time, it will drop INA bearing life. The causes of high temperature INA bearings include: smooth lack or over-smooth smoothness; smoothing agent. Contains impurities; excessive load; INA bearing loss ring; lack of clearance; and high friction of oil seal attack, etc.
Therefore, continuous monitoring of the INA bearing temperature is necessary; whether it is measuring the INA bearing itself or other important parts. If it is in the same working conditions; any temperature changes can indicate that the problem has occurred.
INA bearing temperature timing measurement can be by means of a thermometer; for example, a digital thermometer; can accurately measure the INA bearing temperature and display according to °C or Fahrenheit temperature unit.
INA bearing of importance; meaning that when it is damaged; it will form a stop of the equipment; therefore, the most suitable type of INA bearing should be equipped with a temperature detector.
Under normal conditions; the INA bearing will have a natural temperature rise just after smoothing or smoothing back and continue for one to two days.
