A mathematically rigorous explanation of how manufacturingdeviations and damage on the working surfaces of gear teeth causetransmission-error contributions to vibration excitations
Some gear-tooth working-surface manufacturing deviations ofsignificant amplitude cause negligible vibration excitation andnoise, yet others of minuscule amplitude are a source ofsignificant vibration excitation and noise. Presentlyavailable computer-numerically-controlled dedicated gear metrologyequipment can measure such error patterns on a gear in a few hoursin sufficient detail to enable accurate computation and diagnosisof the resultant transmission-error vibration excitation. How to efficiently measure such working-surfacedeviations, compute from these measurements the resultanttransmission-error vibration excitation, and diagnose themanufacturing source of the deviations, is the subject of thisbook.
Use of the technology in this book will allow quality spotchecks to be made on gears being manufactured in a production run,to avoid undesirable vibration or noise excitation by themanufactured gears. Furthermore, those working in academiaand industry needing a full mathematical understanding of therelationships between tooth working-surface deviations and thevibration excitations caused by these deviations will find the bookindispensable for applications pertaining to both gear-quality andgear-health monitoring.
Key features:
* Provides a very efficient method for measuring parallel-axishelical or spur gears in sufficient detail to enable accuratecomputation of transmission-error contributions fromworking-surface deviations, and algorithms required to carry outthese computations, including examples
* Provides algorithms for computing the working-surfacedeviations causing any user-identified tone, such as 'ghosttones,' or 'sidebands' of the tooth-meshingharmonics, enabling diagnosis of their manufacturing causes,including examples
* Provides explanations of all harmonics observed in gear-causedvibration and noise spectra.
* Enables generation of three-dimensional displays and detailednumerical descriptions of all measured and computed working-surfacedeviations, including examples
