Vibration Response of the Planetary Gears with a Float Sun ...

 · Planetary gearboxes are widely used in mechanical transmission systems due to their large transmission ratio and high transmission efficiency. In a planetary gearbox, the sun gear is usually set to float to balance the sharing of loads among planet gears. However, this floating set will result in the variation of pressure angle, overlap ratio, and meshing phase in the meshing progress and when ...

Frequencies of a gear assembly | PowerMI

Gear natural frequencies: when some kind of gear deterioration develops the natural frequencies of the gears can be excited. Ghost or phantom frequencies: correspond to a relatively rare defect that shows up as a frequency typically higher than the GMF but not directly related to the geometry of the gear. It is due to manufacturing errors that are driven by vibration from the manufacturing ...
