为了尽可能长时间地以良好状态维持轴承本来的性能，必须保养、检测、检修、

In order to maintain as long as possible bearing in good condition original performance, must be maintenance, testing, overhaul, in order to prevent accidents in the first place, to ensure the reliability of operation, increase productivity, economy. Long-term operation of the equipment is concerned, the usual detection and tracking is particularly important, including the rotation detecting program sound, vibration, temperature, status lubricant bearing in accordance with the detection result, maintenance personnel can accurately determine the problem device, make early prevention and solutions. <br>Abnormal rotation abnormality diagnostic analysis sound tone detection analysis is the use of the rotation auscultation bearing operational state analysis method of monitoring long wooden handle common tool is a screwdriver, may be used as an outer diameter of about 20mm hard plastic tubes. In contrast, the use of electronic stethoscope monitoring, help to improve the monitoring of reliability. Bearing in normal working condition, smooth, light, no stagnation, harmonious sound without noise occurred, uniform and continuous audible "buzzing" sound, or low "humming" sound.

In order to maintain the original performance of the bearing in good condition for as long as possible, it is necessary to maintain, detect, repair, and prevent accidents, to ensure the reliability of operation, improve productivity and economy. For long-term operation of equipment, the usual detection tracking is particularly important, testing items include bearing rotation sound, vibration, temperature, lubricant status, according to the test results, equipment maintenance personnel can accurately judge the problem point of the equipment, early prevention and solution.<br>Abnormal rotation almost analytical diagnosis Abnormal rotary tone detection and analysis is an analytical method of monitoring bearing working status by stethoscope, the common tool is the wooden handle long screw screw, or the outer diameter of about 20mm hard plastic tube. In contrast, the use of electronic stethoscopes for monitoring is more conducive to improving the reliability of monitoring. Bearings in the normal working state, smooth operation, light, no stagnation phenomenon, the sound of harmonious and no noise, you can hear a uniform and continuous "whisper" sound, or lower "boom" sound.

In order to maintain the original performance of the bearing in good condition for as long as possible, it is necessary to maintain, detect and repair the bearing in order to prevent accidents in advance, ensure the reliability of operation, and improve the productivity and economy. For equipment in long-term operation, the usual detection and tracking is particularly important. The detection items include the rotating sound, vibration, temperature and lubricant status of the bearing. According to the detection results, the equipment maintenance personnel can accurately determine the problem points of the equipment, and make prevention and solutions in advance.<br>Abnormal rotary sound analysis diagnosis abnormal rotary sound detection and analysis is an analysis method of monitoring the working state of bearings by auscultation. The common tools are long screw drivers with wooden handle, or hard plastic tubes with an outer diameter of about 20 mm. Relatively speaking, the use of electronic stethoscope for monitoring is more conducive to improving the reliability of monitoring. When the bearing is in normal working state, it runs smoothly, briskly, without stagnation, the sound is harmonious without noise, and the uniform and continuous "crash" sound or lower "boom" sound can be heard.<br>
