Book Description
Noise and vibration performance of a gear system is critical in any industry. Vibrations caused by the excitations at the gear meshes propagate to the transmission housing to cause noise, while also increasing gear tooth stresses to degrade durability. As such, gear engineers must seek gear designs that are nominally quiet with low vibration amplitudes. tudes. They must also ensure that this nominal performance is robust in the presence of various manufacturing errors. This thesis research aims at an experimental investigation of the influence of one type of manufacturing error, namely random tooth spacing errors, on the vibratory responses of spur and helical gear pairs. For this purpose, families of spur and helical gear test specimens having intentionally induced, tightly controlled random spacing error sequences are fabricated. These specimens are paired and assembled in various ways to achieve different sequences of composite spacing errors. Static and dynamic motion transmission error measurements from these tests are compared to the baseline case of “no error” gear to quantify the impact of random spacing errors on the dynamic response. These comparisons show that there is a significant, quantifiable impact of random spacing errors on both spur and helical gear dynamics. In general, vibration amplitudes of gear pairs having random spacing errors are higher than those of the corresponding no-error gear pairs. In the frequency domain, gears having random spacing errors exhibit broad-band spectra with significant non-mesh harmonics, pointing to potential noise quality issues.

Book Description
The dynamic load of gears with regular type of spacing error such as full-sine and half-sine type has been analyzed in several previous research works. In this study, the irregular type of tooth spacing error is incorporated with the regular type ones to determine their effect on gear dynamic response. Linear and Parabolic tooth profile modification are applied to evaluate their influence on the dynamic loads of gear systems with regular or irregular tooth spacing errors. All dynamic analyses are conducted using the NASA gear dynamics code, DANST program.The objective of this study is to examine the relationship between gear dynamic load, type and extent of tooth spacing error, and profile modifications. Results obtained from this study can provide proper tooth profile design to minimize the dynamic response of the spur gear systems for a better transmission design.
