Typically, bearing temperatures as the bearing operation began slowly to rise, 1-2 hours to stabilize. Normal temperature of the bearing due to the heat capacity of the machine, heat, speed and load another. If lubricated, install suitable, the bearing temperature is rising quick, unusual high temperatures, in which case you must stop and take the necessary precautions.
Use heat detector to monitor bearing temperatures at any time, and alarm or stop automatically when the temperature exceeds the specified value prevents burning shaft accident.
Often indicates that the bearing is in exceptional conditions with high temperature. High temperatures may also be harmful to the bearing lubricant. Sometimes overheated bearings lubricant that can be attributed to the housing. If bearings are more than 125 ℃ temperature long-term continuous transfers reduce the bearing life. Cause of high temperature bearings including: inadequate or excessive lubrication lubrication, lubricant. Contains impurities, excessive load, bearing loss rings, insufficient clearances, and oil have high friction and so on.
Continuity is necessary to monitor bearing temperature, whether measured or other important parts of the bearing itself. If operating conditions do not change case, any temperature change may mean that the failure has occurred.
Periodic measurement of temperature using a thermometer, such as digital thermometers for precision measurement of bearing temperature in degrees centigrade or Fahrenheit temperature displays.
The importance of bearing to the effect that, when damaged, and will cause the device to shut down, so these bearings should preferably be fitted with temperature probe.
High ambient temperature, grease lubrication is not in keeping with current forged tactical bombs bearing grease with molybdenum disulfide is resistant against high temperature grease, we know the base oils are oil products, plus a small amount of molybdenum disulfide additives for high temperature resistance, heat resistance limit is 120 degrees centigrade. And machine oiling up to more than 30 points, long-term operation and maintenance of this cumbersome oiling control cannot be achieved, armed with thin bearing oil pot watering run outside, lubricating oils have very little access to bearing friction between branches bearing friction.
Forged according to machine the bearing operating temperature up to 200 ° c, far exceed the temperature limits lubricating grease. High temperature without grease based oil will thin out and gradually evaporated, leaving carbon blend, dust slag, molybdenum disulfide as solid block on coagulation moving bearing cage not only loses its lubrication, also hinder the move soon to the proper functioning of the bearing wear, a maximum of 2 weeks would have to shut down and remove the bearing cleaning for the new oil.
Self-lubricating bearing with temperature width, solid lubricant content is sufficient, release average, with good self-lubrication function and occlusion, can effectively protect the journal, achieve sustainable use purposes.
