Low Speed Bearing Analysis – Vibration Institute

If you want to know how to collect vibration data properly on low-speed equipment, this paper is a good choice. This paper starts out describing the nuances and issues of collecting low frequency (low speed) vibration data (below 300 cpm) including instrumentation limitations and ends with a discussion of an actual data collection appliion.

Appliion of the largest Lyapunov exponent algorithm for feature extraction in low speed slew bearing …

1/1/2015· This paper presents a new appliion of the largest Lyapunov exponent (LLE) algorithm as a feature extraction method for low speed slew bearing vibration signals. Although the LLE algorithm has been widely used in some disciplines such as the bio-medical [10] , [11] and finance [12] areas, it has not been explored previously in vibration-based condition …

low speed bearing vibration diagnostics | AMP Maintenance …

20/10/2005· The reason why I didn''t find it jet is in the specific characteristics of bearing witch I have to diagnose. Namely, I would like to diagnose an axial slewing ball bearing with extremely low rotational speed (1RPM to 10RPM). The bearing is not standard, it has external gear and is quite big (pitch diameter = 650mm, nuer of balls = 80).
