Double-rotation four-cycle piston type double-shaft internal combustion engine, pressure flow driver and pump

Abstract

The invention discloses a double-rotation four-cycle piston type double-shaft internal combustion engine, a pressure flow driver and a pump. The double-rotation four-cycle piston type double-shaft internal combustion engine comprises barrel-shaped cylinders, cylinder covers, a crankshaft, a sleeve shaft, rotary pistons, a control shaft and elliptical gears, wherein two groups of the rotary pistons perform reciprocal acceleration and deceleration sinusoidal rotation at an average rotation speed value in a regular rule during work under the control of the control shaft and two groups of the elliptical gears of the same type connected in series with the control shaft; and each cylinder finishes the same four-stroke work in every cycle. The problem of inversion or stillness of the rotary piston does not exist, the acceleration and deceleration smooth transition and corresponding equilibrium conversion between impulse and momentum are realized, and an output or input shaft, namely, the control shaft structurally and stably rotates at a uniform speed; a composite integral structure of the rotary piston solves the problem of requirement on the strength under the conditions of higher rotation speed, high compression ratio and high working pressure; and normal work and operation of the rotary piston are ensured by axial oil supply lubricating technology, limiting self-running-in sealing technology and heat insulating technology. The engine has the advantages of simple structure, high strength, high power, high efficiency and capability of replacing the conventional internal combustion engines in all fields.

Description

(1) Technical field [0001] The invention belongs to the technical field of internal combustion engines, fluid power machinery and pumps, and particularly relates to the fields of rotary piston internal combustion engines, rotary pressure fluid power machinery and rotary piston pressure pumps. (2) Background technology [0002] The commonly used engine is still the crankshaft connecting rod reciprocating piston internal combustion engine with a history of more than one hundred years. Due to its working principle and structure, it has insurmountable shortcomings such as low efficiency, large volume, low speed, and heavy weight. For decades, people around the world have been working hard to develop a rotary piston internal combustion engine with great potential and excellent performance, and two representative test machines have been trial-produced, but they have not been widely used due to the failure of many key technologies application. [0003] One is a triangular rotor ro...

AI Technical Summary

Problems solved by technology

[0006] The deficiencies of the latest existing technical schemes above have: the one is that although the two pairs of rotary pistons cannot reverse, they still stall, and the change of the rotating speed is a sudden change, and the machine Parts withstand high torsional shear force and vibration

Second, regardless of whether the power is directly output from the crankshaft or sleeve shaft, the rotational speed is unstable. If the inertial principle device is used to obtain a stable output rotation, it will inevitably increase the sudden change of the rotating piston and the doubling of the mechanical parts connected to the other shaft. The change of rotational speed also causes the difference in the working stroke time and speed of the four cylinders and pistons, as well as the difference in power and thrust, and the vibration increases.

The third is how to ensure the strength of the parts under high speed, high power, acceleration and deceleration working conditions, and related supporting technologies have not been systematically solved! Therefore, so far, excellent models with such excellent performance and great development prospects that have the potential for replacement still only exist in people's expectations and in research!
