Vibrational analysis gears

Taylor, J. I. 2003. The Vibration Analysis Handbook, 2nd ed. Tampa, FL Vibration Consultants, Inc. While the other two books with Taylor as author or co-author focus on vibration in specific locations (gears and bearings), this work is more general in nature. It discusses machinery vibration in general, time and frequency analysis techniques, how to evaluate the condition of machinery, plus chapters on gears, bearings, and press roll and nip problems. 

Collection and analysis of vibration signatures is a complex procedure. By looking at a vibration spectrum, one can identify which components of the pump system are responsible for a particular frequency component. Comparison of vibration signatures at periodic intervals reveals if a particular component is deteriorating. The following example illustrates evaluation of the frequency composition of an electric motor gear pump system. 

Machine components The EIS should provide information on all components (e.g., bearings, gears, gearboxes, electric motors, pumps, etc.) that make up the machine-train. Since these components generate vibration energy and unique frequency components, this information is essential for proper analysis. At a minimum, the information sheet must include detailed bearing information, passing frequencies, and nameplate data. 

This method provides the means to quickly monitor the mechanical condition of critical machine components, not just the overall machine condition. This technique provides the ability to monitor the condition of gear sets, bearings and other machine components without manual analysis of vibration signatures.

Taylor, J. 1. 2000. The Gear Analysis Handbook. Tampa, FL Vibration Consultants, Inc. Narrow in focus, this work describes methods of gear analysis and appropriate tools, data collection, gear physics and spedlications, and various gear problems and their causes. 

All shafts equipped with instruments are hoUow to take all the cables which are connected via special high-speed slip rings to the static analysis instruments. Rotor vibrations are to be surveyed by pic-up s all other instruments and sensors are as for a common industrial platform gear. The wheel of the slave gear is not equipped with sensors, but the hydraulic axial force device and the input motor drive are connected to it. At the input shaft, the total losses of both gears can be measimed by means of a torque meter coupling.
