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.

Vibration analysis requires a correct identification of the rotational speed of the machine. How the different frequencies of the spectrum are related to RPM, identifying with high accuracy the order of each frequency, is essential for the analysis process.
This webinar will give a brief introduction to planetary gearboxes. Focus will be held on calculations for a simple planetary gearbox stage regarding RPM, GMF, ratios etc. An example with a multistage planetary gearbox will also be explored.

Why wireless sensor Fmax is Critical. Lack of lubrication is a major cause of bearing damage & bearing failure. Therefore, it is critical for vibration sensors to be able to detect the higher frequency vibration resulting from lack of lubrication, which is generally far above 1kHz..

Overhead cranes are often a single source cause of downtime in any manufacturing facility, especially when discussing those performing services in a steel mill’s melt shop. Often, these assets do not have redundancy that would allow for one to be taken....

Failure mechanisms such as misalignment, balance, or lubrication issues can cause machinery failure. Many of these problems can be identified using standard non-destructive testing (NDT) methods including vibration analysis, infrared thermography, and tribology....

So what does it really mean to increase lubricant cleanliness? We read various articles and textbooks that talk about how increasing the cleanliness of an in-service oil will increase the life of a component and the lubricant, but how do we make that happen...
