The Detection of Gear and Bearing Defects Using Electrical and Current Signature Analysis
In this presentation we will discuss how to use ESA/MCSA to detect bearing and gear defects in a variety of driven equipment including geared elevators, cooling towers, and other applications, even when we are looking at a few RPM. We will discuss how to determine the correct frequencies as well as how to determine the defect severity amplitudes in -dB, and how to isolate the machine you are testing from nearby machines. Several case studies will be presented including an AC building elevator, a cooling tower, and at least one complex (multi-stage) gearbox using both data collection and continuous monitoring.

Five Minute Facts
Gear Defects and Faults
Gear faults typically occur in the teeth of a gear mechanism due to fatigue, spalling, or pitting. These can be manifested as cracks in the gear root or removal of metal from the tooth surface. Gears are the main elements of power transmission in many industrial applications and are subjected to significant stresses and loading.
