Abstract
The health condition of worm-wheel gearboxes is critical for the reliable and continuous operation of passenger escalators. Vibration sessors have been widely installed in such gearboxes and vibration levels are usually utilized as health indicators. However, the measurement of vibration levels is not robust in slow speed bearing condition monitoring. In this paper, the health condition of two slow speed bearings were evaluated using vibration data collected from sensors installed in the shaft of a worm wheel gearbox. It has been shown that the vibration level fails to indicate the bearing health condition. The assessment accuracy can be improved by combining several simple methods.
