To make the operation of FAG bearings performance, in satisfactory condition to maintain a long period of use, always bearing the purposes of investigation and protection of well-nourished recuperation, this investigation and protection of well-nourished recuperation, is secured for early fault prevention, adaptation of expectations based on the operating conditions of the machine operating standards, the purposes of investigation and protection be nursed back to on a regular basis.
Periodic checks generally use the following method: operational status under review on the basis of FAG bearings rolling sound, vibration, temperature checks and lubricant properties check, supplement or replacement of the lubricant time to judge. Check in operation and fault handling. Bearing checked full observation of periodic inspection and replacement of the machine-breaking down to bearing, check the Raceway surface and there is no damage and could use it again.
Before the bearing can be used, first of all check the bearing surface, thus we can infer the bearing is load requirements and standards. Inspection should FAG bearing surface under the flood operation, the bearing to check for cracks and surface detail.
First, the sound of rolling bearing: bearing even subtle damage such as stripping, using acoustic logging on in the operation of large rolling sound and the sound quality of FAG bearings to reflect. May announce its abnormal tone and unruly sounds, using the acoustic measurement can differentiate.
Second, FAG bearing vibration:
Such as indentation, rust, cracks, spalling, wear are reflected in the measurement of bearing vibration, FAG bearing vibration sensitive to bearing damage. So, after a remarkable bearing vibration Measurer (frequency analysis) can measure vibration of large, detailed status after frequency weigh out exception. Measured values using the premise or the sensor installation status of bearing and difference, which demand prior to each of the mechanical analysis discriminant specification when it was compared with the measured value.
Third, the temperature of the bearing:
Ordinary bearing outside of room temperature can be speculations, FAG bearing temperature. If oil holes can directly measure the temperature of bearing outer ring is more appropriate. Fro, bearing temperatures beginning followed the operation gradually increased, 1-2 hours later arrived in unchanged form. Normal temperature machinery bearings heat capacity, heat dissipation, speed and load while differences. If smooth, install appropriate, bearing temperature quick rise, will show abnormal high temperature when necessary to suspend operation, bearings, accepted the need for preparedness approach. Because the effects of temperature, speed, load, smooth, broad temperature value is only revealed in the table limits. Using heat detector can temperature monitoring of FAG bearings task at any time, and complete the temperatures across the active alarm or abort when the rule value to avoid burning shaft rebellion attack.
Four, lubrication:
Without normal lubrication, lubrication on fatigue life of FAG bearings and friction, abrasion, temperature, vibration, and so has important implications. Bearing will not work. Analysis of cause of bearing damage marked, 40% left and right bearing damage related to poor lubrication. Therefore, good lubrication of the bearing is the effective measure to reduce bearing friction and wear.
