Abstract:
1. A planetary motor comprising: a cylindrical outer gear having a bore with a centerline and an internal surface with circumferentially distributed and radially directed teeth, a means for mounting said outer gear such that said outer gear is constrained to move in rotational motion about the centerline of said outer gear, a cylindrical planetary gear having a bore and an external surface having circumferentially distributed and radially directed teeth, a means located within said planetary gear bore for applying a fluid pressure driven force to specified points on said planetary gear so as to cause said planetary gear to move in translational-circular motion about the centerline of said outer gear, wherein said planetary gear is configured to fit within the bore of said outer gear in such a manner that a plurality of said outer gear teeth and said planetary gear teeth intermesh, and wherein said planetary gear and outer gear teeth are configured so as to cooperate such that the translational-circular motion of said planetary gear causes said rotational movement of said outer gear.
