“…[61,62] can be further improved to fit for the helical gear pair with tooth crack. (4) Many researchers discussed the effects of the model of spur gear systems on the system vibration responses [68,71]. It is important to select an appropriate dynamic model for numerical simulation because a model with a large number of DOFs, such as FE model, will consume huge computer resources and a small DOF model may lead to a large discrepancy between the model and the real gear system.…”

“…Intermittent operation is also possible, and models can display both quiet (permanently meshed) and rattling behaviours under seemingly identical operating conditions [3][4][5]. Detailed reviews of gear modelling are given bÿ Ozgüven and Houser [6] and Parey and Tandon [7].…”

The interaction between eccentricity and an external forcing fluctuation in gear rattle response is investigated experimentally. The experimental rig consists of a 1:1 ratio steel spur gear pair, the input gear being controlled in displacement and the output gear being under no load. Gear transmission errors recorded using high accuracy encoders are presented. Large variations in backlash oscillation amplitude are observed as the relative phase of the input forcing and the sinusoidal static transmission error due to eccentricity is varied. A simplified mathematical model incorporating eccentricity is developed. It is compared with experimental findings for three different gear eccentricity alignments by way of plots relating backlash oscillation amplitude to forcing amplitude and phase relative to eccentricity sinusoid. It is shown that eccentricity does not fully account for the experimentally observed large variations in amplitude. Through analysis of the experimental data, it is suggested that further tooth profiling errors may explain the discrepancies.

“…Different degrees of the TB: 0%, 25%, 50%, 75% and 100% of a tooth width are simulated with and without influence of friction. The coefficient of friction is assumed to be constant with a value of 0.1, which is the mean value to that considered by Howard et al (2001) and Parey and Tandon (2003). Figure 16 shows the spectrum compassion of translational responses for the health and 100% breakage cases between friction-free and friction inclusion.…”

To develop accurate diagnostic techniques, this study examines the dynamic responses of spur gear transmission system with including frictional effects on a tooth mesh process. An 8-degreeof-freedom model is developed to include the effects of supporting bearings, a driving motor and a loading system. Moreover, it takes into account not only the time-varying stiffness, but also the time-varying forces and moments due to the frictional effect. The latter causes additional vibration responses in the direction of the off-line-of-action (OLOA). To show the quantitative effect of the friction, vibration responses are simulated under different friction coefficients. It shows that an increase in friction coefficient value causes a nearly linear increase in the vibration features of diagnostics. However, features from torsional responses and the principal responses in the line-of-action show less changes in the vibration level, whereas the most significant increasing is in the OLOA direction. Furthermore, the spectral peaks at the rotational and sideband frequencies are influenced significantly by small breakage defects, especially when the friction effect is taken into account. In addition, the second and third harmonics of the mesh frequency are more influenced than the first harmonic component for all motions, which can be effective features for both indicating lubrication deterioration and improving conventional diagnostic features.
