Helical Gears and Vibration In Terms Of PeakVue

This paper illustrates that the application of vibration analysis has been quite successful in a number of areas. In rotary machinery, vibration analysis is quite effective in the detection of primary characteristics of machines and consequent extraction of faulty characteristics. Vibration analysis for faults in gear systems is largely employed in various industries, such as transport and aviation, where train drives, as well as helicopter engines among other rotor systems, are usually fitted with vibration sensors for monitoring their health condition. Each machine even in their best operating condition tends to have some form of vibration, which will have a certain level that may be deemed natural or normal. Nevertheless, when a machinery vibration increases, such a change can be attributed to a mechanical problem. In helical gears, just as is the case with other types of gears, vibrations can be associated with gear tooth contacts. There are different techniques employed in the detection of faults by vibration analysis. According to Shreve, these include the time-domain technique, frequency domain technique and the time-frequency domain technique. The time domain technique normally entails analyzing certain statistical aspects of vibration signals like standard deviation, the peak level as well as the skewness of a vibration signal. On the other hand, the frequency domain technique is a confirmatory approach that normally provides additional information based on the analysis of the time-frequency details of a vibration signal. This is achieved by the use of power spectra and vibration amplitude. Adams explains that vibration analysis is quite efficient due to the fact that virtually all rotor machinery have some vibration at least once in a single revolution frequency component. This is due to the fact that it is almost impossible to have a perfectly balanced rotor. ...Show more

Enveloping and PeakVue
In the PeakVue technique, the capturing of the accurate peak value diagnosed inside the time waveform related with each of the impacting events provides the analyst with information regarding severity of the damage too. PeakVue is a tool that can obtain the amplitude trend of maximum waveform and stress wave spectral frequency distribution; and these pieces of information substantially improve the quality of fault severity assessment (Robinson and Berry, 2001).

Enveloping and PeakVue
Peakvue as a technique captures the peak values of the stress waves that are produced and then remits the repetition frequency of the impacts via a spectral analysis. For a professional using peakvue, the most important factors are the peak values. These values are captured as resonation of stress waves.

Health and Safety (Exposure to vibration )
Vibration Exposure to vibration by workers has not been viewed as a health hazard by many. Vibrations can be felt, but the determination of its harmful effects remains next to impossible. Vibration is defined as oscillations instigated mechanically from an object and originate from an equilibrium point.

Vibration of Continous Media
Assuming f(x) is a real valued function, the function defined by lim{h right 0}{{f(x+h)~-~f(x)}/{h}} For this function, if the derivative exists at each point along the curve, then f’(x) = lim{h right 0}{{f(x+h)~-~f(x)}/{h}} This definition of derivative of f(x) is the First Principle of Derivatives.

However, since the elastic stiffness is independent of the flight speed, whereas the aerodynamic moment is proportional to the square of the flight speed, there may exist a critical speed, at which the elastic stiffness is barely sufficient to hold the fin in the disturbed position.
