Investigation of the Noise and Vibration of Planetary Gear Drives

摘要

With the aim of reducing the operating noise and vibration of planetary gear sets used in automotive automatic transmissions, a meshing phase difference was applied to the planet gears that mesh with the sun and ring gears. Shaved and hardened helical gears with and without grinding were used as the component gears for testing under varying rotational speeds and tooth loads. The experimental results clearly showed that planetary gear set noise and vibration were reduced when a meshing phase difference was applied.
