A planet crankshaft transmission mechanism comprises a machine body, a crankshaft, a left crankshaft gear, a left inner gear ring, a right crankshaft gear, a right inner gear ring, a piston, a left supporting arm, a right supporting arm, a left supporting shaft and a right supporting shaft; the crankshaft penetrates the left crankshaft gear and the right crankshaft gear and is fixedly mounted; the left crankshaft gear and the right crankshaft gear are meshed with the left inner gear ring and the right inner gear ring which are fixed to the machine body respectively; the crankshaft can be rotatably mounted on an eccentric hole of the left supporting arm and an eccentric hole of the right supporting arm; due to the distance between the eccentric hole axes of the left supporting arm and the right supporting arm and central axis holes of the left supporting arm and the right supporting arm, the eccentric holes and the central axis holes have the external divergence relation; the left supporting arm and the right supporting arm are rotatably mounted on the left supporting shaft and the right supporting shaft through the middle axes; the left supporting shaft and the right supporting shaft are mounted on the machine body; and the piston is rotatably mounted on a crank throw of the crankshaft. The planet crankshaft transmission saves energy, and is environment-friendly, durable, low in maintenance cost and quite suitable for the condition that the stroke of the piston is large.
