摘要：A stepper motor suitable for use in a medical imaging environment has (a) acylindrical central gear having an external surface with circumferentially distributed andradially directed teeth, (b) a shaft for mounting the central gear such that it is
constrained to move in rotational motion about its centerline, (c) a cylindrical hoop gearhaving a bore with an internal surface having circumferentially distributed and radiallydirected teeth, (d) level arm crank mechanisms for mounting the hoop gear such that it isconstrained to move in translational-circular motion about the central gear's centerline,wherein this central gear is further configured to fit within the hoop gear's bore in such amanner that a plurality of the central gear and hoop gear teeth intermesh and cooperateso that the planetary movement of the hoop gear causes the central gear to rotate, and(e) piston mechanisms for applying a fluid pressure driven force to specified points on thehoop gear so as to cause its movement.
