In the process of using spherical bearings due to improper operation, insufficient lubrication, rust and corrosion, and a number of other factors, such as current, external material, eccentric and result in greatly reduced service life of the bearing. Therefore is necessary in the course of using SKF bearings have sufficient knowledge and understanding of the prevention measures.
Another lubrication method--oil mist lubrication of the bearing, it is a micro-lubrication, simply refers to a very small amount of oil to meet the rolling bearing lubrication requirements. Oil mist lubrication is oil mist lubrication oil mist generator, the SKF bearings are lubricated by oil mist. In rolling bearing working surface due to oil mist into droplets, in fact, still maintains a thin oil lubrication of rolling bearings. This lubrication should be aware of the following two points:
1. Select oil viscosity should not exceed 340mm/s (40 degrees) because of fog effects will not be up to high viscosity.
2. oil mist lubrication may partially with fugitive air, pollution of the environment. Oil mist separator can be used to collect when necessary, or using ventilation to scavenge.
When the spherical bearing rolling element linear speed was higher, often using oil mist lubrication to avoid too many other methods of lubrication because oil supply, increased internal friction increases of oil bearing operating temperature. Oil pressure is about 0.05-0.1mbar in General.
Use heat detector to monitor bearing temperatures at any time, and temperature alarm when exceeding a specified value or stop preventing the burning shaft accident. High temperature often indicates that the bearing is in an abnormal situation. High temperature but is also harmful to the bearing lubricant. Sometimes overheated bearing could be attributed to the bearing 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.
Continuous monitoring of rolling bearing temperature is therefore necessary, SKF bearing both the bearing itself or other important parts of the measure. If operating conditions do not change case, any temperature changes may have occurred at fault. Bearing temperature measurement using a thermometer on a regular basis, such as digital thermometers for precision measurement of bearing temperature in Celsius or Fahrenheit temperature displays.
Spherical bearing temperature, generally have the bearing outside of room temperature can speculate if oil hole can directly measure the temperature of bearing outer ring, bearings are more appropriate. Usually, temperature of the bearings with bearing operation began to rise slowly, 1-2 hours to stabilize. SKF bearing normal temperatures due to the heat capacity of the machine, heat dissipation, speed and load another. If lubricated, install the appropriate, the bearing temperature is rising dramatically, and abnormal high temperature occurs, in which case you must stop and take the necessary precautions.
