다국어 초록 (Multilingual Abstract)

The area of gear vibration and noise, has recently been the focus of many studies. The proper kinematic and geometric design of gears, the mathematical modeling of gear system are essential for a good design. This work present a gear design for reducing noise, and practical approaches used for machinery noise reduction along with the summary of methods available for predicting gear noise in terms of the transmission error, and show a comparative study with other methods. A new tooth profile modification is proposed for reducing vibration and noise of involute gears. The method is based on the use of cubic spline curves. The tooth profile is constrained to assume an involute shape during the loaded operation. Thus the new gear profile assures conjugate motion at all points along the line of action. The new profile is found to result in a more uniform static transmission error compared to not only standard involute profile but also modified profile thereby contributing to the improvement of vibration and noise characteristics of the gear.
