Vibration during operation and temperature on the IKO oilless bearing damage

Generally, if the correct use of oil-free bearings, can be used to achieve fatigue life. But there will be unexpected injury prematurely, not resistant to use. This early damage, as opposed to a fatigue life, use limit to the character of the called the fault or accident. Much due to the installation, use, do not pay attention on the lubrication, intrusion of foreign bodies from outside, to the shaft, shell heat affected study enough. About IKO bearing damage status, such as: no oil bearing ring guard card, as a reason to consider, lack of lubricant, not suitable for, for the defect of oil discharge structure, foreign invasion, bearing installation error, the deflection of the shaft is too large, also can have these reasons. Therefore, only investigate bearing damage, the real reason is hard to come by injury. However, the use of machinery, if you know the bearing conditions of use, bearing the surrounding structure, to get hold of before and after the accident, combined with several damage status and causes of bearing, can prevent the similar accident happen again. A, bearings IKO bearing oscillations of oilless bearing damage is very sharp, such as peeling, indentation, rust, crack and abrasion will be reflected in the survey of bearing vibration, so after see fit, and the use of special bearing vibration survey ( Frequency profiler, etc. ) Can survey the oscillation of the volume, through the frequency points can't infer the abnormal state of specific things. Measured Numbers due to the use of the bearing condition or sensor installation position and is not the same, because the demand in advance of each machine survey value analysis is confirmed after judgment standard. IKO bearings, bearing temperature, average has a bearing on the surface of the outdoor temperature can measure out, if can use oil hole survey temperature of the bearing outer ring directly, is more appropriate. Generally, IKO bearings as oilless bearing operating temperature to rise slowly, 1 - Achieve safe condition in 2 hour. The normal temperature of bearing the amount of heat capacity of machinery, calories, rotating speed and load and not the same. If lubricating oil, installation of fitting, bearing temperature will rise sharply, will show abnormal high temperature, then make sure to rest, take indispensable to guard against the solution. Using thermal device can monitor any time testing IKO bearing temperature, and successfully implemented e. semi-automatic alarm when temperature exceeds or rest to avoid burning shaft accident. Expressed in high temperature often is in abnormal conditions. High temperature and to the detriment of the IKO bearing lubricating oil agent. Sometimes overheated bearings can be classified to the bearing lubricating oil agent. Without oil bearing in more than 125 ℃ temperature even transfer to reduce bearing of survival for a long period of time. Comprised of actuating high temperature bearing cover: lubricating oil is not enough or not for himself what the lubricating oil, lubricating oil agent. Contains impurities, heavy load, bearing ring, space is not enough, and the initiation and the high friction of the bearing oil seal and so on. Because of the monitor's sex detection IKO bearing temperature is indispensable, whether measured bearing parts itself or other matter. If running condition has not changed things, no matter what the temperature change can express has malfunctioned. IKO bearing temperature measurement by using a thermometer, regularly cases according to the number of the original word thermometer, bearing temperature measurement can be very accurate and it is in accordance with ℃ or Fahrenheit temperature unit. Shut the oilless bearing, means when the destruction, will lead to the facility downtime, because this kind of bearing the best agent amount observer should be equipped with temperature. Normal things, bearing in just after the lubricating oil or grease will be a natural temperature rise and continuous one to two days.
