Condition Monitoring Tasks and Options • 11 2 Condition Monitoring 2.1 Tasks and Options The growing cost pressure within the global competition increasingly forces companies to maximize existing saving potentials and to implement measures for more efficiency. In the maintenance sector this means the assurance of a fault free production process, the avoidance of unscheduled machine downtime and the optimum exploitation of the installation lifespan.

Condition Monitoring Machine Condition Monitoring with VIB-I/O Modules • 13 2.2.2 Roller Bearing Analysis The VIB-I/O module uses the shock pulse method to analyze the roller bearing. This method provides the measurement of mechanical shock impulses. They arise during operation from the contact between the roller bearings and the rolling path in the load zone and spread in waves in the material. The signals measured during the rolling process divide in the carpet value and the peak value.
• Condition Monitoring Machine Condition Monitoring with VIB-I/O Modules 2.2.3.2 Shock Impulse Evaluation The following scale for the evaluation of shock impulses has been created. The measured shock impulses are classified here in the categories of the bearing state, from 'good, to 'limited' and finally to 'poor'. dB N 60 poor 40 limited 20 good 0 50% 100% Fig. 2.2.
Condition Monitoring Machine Condition Monitoring with VIB-I/O Modules • 15 dB N 60 poor 40 limited 20 good 0 Time Fig. 2.2.3-2: Low carpet value g064518e The carpet value rises when the lubrication layer decreases and rolling path and roller bearing touch at more and more locations. The following diagram shows an increased carpet value. dB N 60 poor 40 limited 20 good 0 Time Fig.. 2.2.
• Condition Monitoring Machine Condition Monitoring with VIB-I/O Modules dB N 60 poor 40 limited 20 good 0 Time Fig. 2.2.3-4: Shock impulses at bearing damage g064520e 2.2.4 Damage History 2.2.4.1 Three Stages to Evaluate a Roller Bearing State By performing continuous shock impulse measurements, changes in the bearing condition can be easily detected. The operating time starts at 0 % with the installation of the bearing and ends with the bearing damage at 100 %.
Condition Monitoring Machine Condition Monitoring with VIB-I/O Modules • 17 Deciding factor for the planning of bearing changes is the trend measurement and change analysis. Continuous shock impulse measurements clearly show changes in the bearing condition during operation. Note New bearings may require a break-in time, during which the base noise is decreasing. 2.2.4.2 The Evaluation Scale The roller bearing evaluation scale is divided in three stages: 1. Good operating condition 2.
• Condition Monitoring Machine Condition Monitoring with VIB-I/O Modules peak value reaches increased values and the difference between peak values and carpet value rises (see diagram below). dB N 60 poor 40 limited 20 good 0 Time Fig. 2.2.4-3: Limited operating condition g064512e A visible increase in the peak values and a rising difference between carpet value and peak values are a sure indication for a bearing damage in progress. 2.2.4.2.
Condition Monitoring Machine Condition Monitoring with VIB-I/O Modules • 19 2.2.5 Typical Shock Impulse Diagrams 2.2.5.1 Bearing in Good Condition Peak values between 0 dBn and 20 dBn do not require a further analysis. The bearing is in good condition. Brand-new bearings and small needle roller bearings may show values below 0 dBn. Such low values, however, should be verified since they could be caused by a wrong measuring position or a faulty measurement. dB N 60 poor 40 limited 20 good 0 Time Fig.
• Condition Monitoring Machine Condition Monitoring with VIB-I/O Modules 2.2.5.3 Installation Errors or Insufficient Lubrication A high carpet value and a peak value insignificantly above, but still in the limited range, indicate either an installation error when the bearing was installed, or insufficient lubrication. The bearing should be re-lubricated and measured again after some hours. If the lubrication was insufficient, the values should decrease.
Condition Monitoring Machine Condition Monitoring with VIB-I/O Modules • 21 2.2.6 The Measuring Point Preferred measuring location is the place where the shock impulse signals can be received with the least loss. In the case of machinery with rotating masses, the bearing or the bearing enclosure are the ideal measuring locations. Four rules for the selection of a measuring point 1. Material Transition Every additional material transition dampens and/or reflects the signal to be measured.
• Condition Monitoring Machine Condition Monitoring with VIB-I/O Modules 2. Short Measuring Path The measuring path between bearing and measuring point should be as short and direct as possible. Fig. 2.2.6-2: Short measuring path g064525x Note Shock impulse signals are weakened with increased signal path. Therefore, measurements should be only taken in the dashed area of the drawing. 3.
• 23 60 ° Condition Monitoring Machine Condition Monitoring with VIB-I/O Modules 60 ° Fig. 2.2.6-3: Measurement in load direction g064523x Fig. 2.2.6-4: Emission window g064522x Shock impulses spread in waves. The shock impulses are transmitted from the outer rolling path to the bearing enclosure. Because the width of a bearing is limited, shock impulse signals can only be transmitted within a ±60° sector from the vertical to the contact surface between roller bearings and rolling path.
• Overview Condition Monitoring Components 750-645, 750-925 Machine Condition Monitoring with VIB-I/O Modules 4. Measurements as Close to the Bearing as Possible Shock impulses are weakened by extended measuring paths and material interruptions. Hence, shock impulses should be recorded before an important portion of the signal strength is lost. For this reason, measurements should be taken as close as possible to the bearing.
