AußenringdefektFrequenzen

AußenringdefektFrequenzen, a term originating from German, translates to "outer ring defect frequencies" in English. This concept is relevant in the field of vibration analysis and condition monitoring, particularly for rotating machinery such as bearings. It refers to the characteristic frequencies at which vibrations are generated when defects occur on the outer race of a rolling element bearing.

When a defect, such as a spall or crack, is present on the outer ring of a bearing, each time a rolling element passes over this defect, it generates a distinct impact. These impacts create vibrations within the bearing and the surrounding structure. The frequency of these vibrations is directly related to the rotational speed of the machine and the geometry of the bearing, specifically the number of rolling elements and the bearing's pitch diameter.

The calculation of AußenringdefektFrequenzen involves specific formulas that take into account parameters like the bearing's outer diameter, the diameter of the rolling elements, and the shaft's rotational speed. By monitoring and analyzing vibrations at these predicted frequencies, maintenance personnel can detect the presence of outer ring defects, even before they lead to catastrophic failure. This allows for proactive maintenance, reducing downtime and preventing costly damage. The detection of these frequencies is a crucial aspect of predictive maintenance strategies.
