Gear shape optimization for non-circular gearing
IOP Conference Series: Materials Science and Engineering, 2021 Abstract The quality of gearings is largely decided by their geometric design. If the geometric design is incorrect, the reliability of the transmission will not be ensured even by the use of the highest quality materials. Conversely, sometimes excellent geometric gear design can save expensive material costs.

Vibration and Noise Characteristics of Elliptical Gears due to Non-Uniform Rotation
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2012 Elliptical gear is a typical non-circular gear, which transmits a variable-ratio rotation and power simultaneously. Due to the non-uniform rotation, the vibration and noise of elliptical gears demonstrate particular characteristics which should be paid ...
