Materials which are used in rotating elements face with
faster deterioration due to vibration, acoustic emissions and the most common
rotating element in dynamic mechanical systems is the bearing element. Due to
surface and micro-structure features, components of the bearings’ frictional
effect vary in different characteristics such as acoustical response. Particulary,
as the oil starvation occur in bearings by the time, the material of the
bearing inner race, outer race, balls gain higher priority for preventing
internal and external failures. In this study, some failure modes are
experimented with ball bearings made of 100 Cr 6 (SAE 52100 chrome steel) and
evaluated respect to material acoustic response. According to the conclusion,
acoustic characteristic responses are achieved in time-domain and frequency-domain
in different rotating speeds; and also found that overall RMS values of the
acoustic signals are in increasing trend respect to the material deterioration
response.
