Abstract
The new generation of condition monitoring and diagnostics systems differs by the detailed solution of diagnostic problems that allows making a step from machine vibration state monitoring to the monitoring of the machine technical condition. Most rotating machine defects can be detected by such a system much before dangerous situations occur. It allows the efficient use of stationary on-line continuous monitoring systems for condition monitoring and diagnostics as well. A real-time system for condition monitoring of Gearbox can reduce expenses of maintenance of it used in industry. It is based on vibration signature analysis concept using the vibration information as acquired from the various bearing locations of a Gearbox. The aim of vibration monitoring is the detection of changes in the vibration condition of the object under investigation during its operation. The cause of such changes is mainly the appearance of a defect. The vibration measurements can be conducted without any change in the operation mode of the object The objective of this paper is to detect the fault in Gearbox by the interpretation of vibration data and spectrums. The spectrums shows the fault in Gearbox when Gearbox is operated at different Gears on full loads.
