Abstract

The invention relates to a planetary gear differential power plant. By arranging an eccentric movable spindle on each planet wheel in more than two planet wheels in the planetary gear mechanism, the movable spindle rotates around the centre line of the planet wheel shaft while revolving. Since the rotation direction of the eccentric movable spindle can be identical to or opposite to the revolution direction, the eccentric movable spindle produces a speed difference in the revolution process. A sliding rod is correspondingly arranged on the movable spindle, and movably and rotatablely connected with the central shaft of the planetary gear, such as a planet carrier shaft and a sun gear shaft, so that the sliding rod is enabled to rotate around the central shaft of the planetary gear. When the included angle between the eccentric movable spindle corresponding to each sliding rod and the planet wheel shaft the included angle between the eccentric movable spindle corresponding to each sliding rod and the central shaft of the planetary gear are different, the rotation rate of the sliding rod corresponding to the central shaft of the planetary gear can be different, thereby forming the differential power plant. Thus, the invention can be designed into various rotary pumps, rotary engines, rotameters and the like.
