Abstract
This article considers problems arising from conventional techniques used to diagnose faults in the rolling-element bearings of rotor-bearing systems, with dampers used in centrifugal milk processing machinery. Such machines include milk separators and related processing machinery. The article asserts that where the rotor-bearing system is equipped with vibration dampers, conventional fault diagnostic measurements produce inadequate results. Hence, for rotor-bearing systems of this type, this article suggests a different way to diagnose faults in bearings and monitor conditions.
Highlights
Rolling-element bearings are a key component in rotating machinery[1] such as turbomachinery, electric motors, machine tools and gearboxes
We propose to use the direct bearing vibration measurement method for rotor-bearing systems equipped with vibration dampers to improve the reliability of fault diagnostics
The proposed diagnostic technique allows us to monitor the condition as well as perform periodic measurements. These experimental studies demonstrate that the design and type of the bearing vibration damping system have the greatest influence on the accuracy of diagnostic measurements
