The swing-arm double-gear power transmission mechanism is a type of engine that eliminates the crankshaft structure of the traditional cylinder piston connecting rod crankshaft engine, replacing it with a swing-arm double-gear power transmission mechanism. This mechanism consists of a straight rod fixed to the piston, a U-shaped gear carrier fixed to the straight rod, and two fork plates under the U-shaped gear carrier, each with a long, narrow opening in the middle. At the rear end of each fork plate, there is also a shaft hole. Between the two fork plates of the U-shaped gear carrier, a pair of meshing gears are installed. A connecting plate is installed on each side of the gears, and each connecting plate has a shaft hole corresponding to the gear shaft position, allowing for sliding fit with the gear shaft or a rolling bearing fit. After passing through the connecting plates, both ends of the gear shaft are fixed to a pair of swing arms. The other end of the upper gear's swing arm is fixed to the power output main shaft and the flywheel energy storage sub-shaft, respectively. The lower gear's swing arm... At the other end, it engages with the shaft holes or rolling bearings on the two fork plates of the U-shaped gear carrier. Driven by the engine starter, the main shaft transmits rotation to the upper gear of this structure, which in turn transmits it to the meshing lower gear. This, in turn, drives the U-shaped gear carrier to move along the direction of the cylinder piston, preparing the engine for the four-stroke power stroke. When the engine ignites and begins the power stroke, the piston drives the U-shaped gear carrier, and through the initial operating mode, the gear set, in turn, pushes the main shaft to continue rotating in the direction it began to rotate, performing power. At the end of the power stroke, the flywheel releases its stored energy, continuing to complete the other strokes of the engine, forming a continuous cycle of power delivery. Because of this continuous cycle, the main shaft continuously outputs power, eliminating all the defects of traditional crankshaft engines. This swing arm double-gear power transmission mechanism has an extremely simple structure, reliable operation, is very easy to manufacture, process, install, and maintain, has low cost, and extremely high thermal efficiency. It is suitable for all applications and equipment using traditional cylinder piston crankshaft engines.

A horizontal axis rotational force generator is introduced, utilizing fluid flow to drive motion. The system includes one or more rotating mechanisms, each with multiple blades positioned at equal phase angle intervals. These blades revolve around a horizontal shaft while simultaneously rotating around parallel sub-shafts when exposed to fluid pressure, producing torque on the main shaft. A support structure holds the shaft and allows stable axial rotation at designated heights. A gear interlocking unit adjusts angular velocities, shifting blade revolution speeds to half their value in the opposite direction, and transfers the result to the main shaft. As blades pass vertically above the shaft, their orientation is controlled so that surfaces align horizontally or vertically relative to the shaft. This ensures blades consistently generate maximum rotational force on the horizontal plane, efficiently converting fluid flow into usable mechanical energy.
