Abstract
A method of superfinishing a large hollow wheel gear in a vibratory bowl having a center hub comprises at least partially filling the vibratory bowl with an amount of finishing media, laying the gear horizontally into the bowl over the center hub, supplying a quantity of an active chemistry into the bowl and agitating the vibratory bowl at a frequency such that the gear settles into and is fully supported by the media. By controlling the process parameters, the hollow wheel gear may be caused to rotate in the media and can be made to float at a desired level. The method is particularly suitable for hollow wheel gears for large wind turbines.
