Problems solved by technology

[0004] Although diesel engines and gasoline engines are widely used, the crankshaft-connecting-rod mechanism has become a classic structure of power transmission; but this mechanism still has many disadvantages: 1. The mechanical transmission efficiency is low: the force of the gas acting on the piston is transmitted through the connecting rod For the crankshaft, two component forces are generated at the connecting position of the crankshaft and the connecting rod
Although this technical solution also adopts the structure without crankshaft and connecting rod, the mechanism is too large and is not conducive to the layout of the whole machine
At the same time, there are still problems such as complex structure and high cost; vibration caused by reciprocating inertial force is not considered

Embodiment 1

[0035] Such as Figure 1 to Figure 6 As shown, this internal combustion engine without crankshaft and connecting rod includes components such as a cylinder block 10, a rack 2, an output shaft 7, a piston 1 and a gear transmission mechanism.

[0036]Specifically, there are two racks 2, the two racks 2 are parallel and the teeth are opposite to each other. Both ends of each rack 2 are fixedly connected with a piston 1 , so it can be seen that the number of pistons 1 is four. According to the actual situation, the piston 1 is connected with the rack 2 to improve the mechanical strength. The connection between the rack 2 and the piston 1 is located at the center of the end surface and is opposite to the top surface 1e of the piston 1 connected to the same rack 2 .

[0037] There is a combustion chamber in the cylinder 10 that corresponds to the position and direction of movement of the piston 1; therefore, the piston 1 and the rack 2 are positioned on the cylinder 10. When the f...

Embodiment 2

[0052] The structure and principle of this embodiment are basically the same as that of Embodiment 1, except that the gear transmission mechanism includes an input gear 3 meshing with one rack 2 and an input gear meshing with another rack 2 Two 6 and the intermediate gear shaft 4 positioned on the cylinder block 10; between the input gear one 3 and the intermediate gear shaft 4, the one-way clutch one that makes the input gear one 3 only drive the intermediate gear shaft 4 to rotate in one direction 5 are connected; the output shaft 7 is fixedly connected with the transmission gear 9 meshed with the tooth portion of the intermediate gear shaft 4; the input gear two 6 and the output shaft 7 are connected by making the input gear two 6 only along the relative Drive the one-way clutch two 8 that output shaft 7 rotates in the opposite direction of input gear one 3 driving intermediate gear shaft 4 rotation direction to link to each other.

[0053] Simply put, the input gear one 3 ...

Abstract

The invention provides a combustion engine without a crank shaft connection rod, which belongs to the technical field of mechanical engineering and resolves the problem that an existing combustion engine is too large in structure, inconvenient to arrange, complex in structure, high in cost and free of considering of vibration brought by reciprocation inertia force. The combustion engine without the crank shaft connection rod comprises a cylinder body, two horizontally arranged racks located on the cylinder body and an output shaft located on the cylinder body. Two ends of each rack are fixedly connected with a piston, a combustion chamber corresponding to the position and the motion direction of the pistons is arranged in the cylinder body, and a gear transmission mechanism capable of switching axial motion of at least one rack into circumferential motion of the output shaft is arranged between the racks and the output shaft. The combustion engine has the advantages of being high in transmission efficiency, free of vibration, simple in structure, reasonable in design and the like.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering, and relates to an internal combustion engine, in particular to an internal combustion engine without a crankshaft connecting rod. Background technique [0002] The internal combustion engine mixes liquid or gaseous fuel with air, and directly inputs it into the high-pressure combustion chamber inside the cylinder to generate power. Obviously, the internal combustion engine is a kind of power machinery, which is a heat engine that directly converts the heat energy released into power by burning fuel inside the machine. [0003] Common diesel engines and gasoline engines mix fuel and air, burn them in their cylinders, and release heat to generate high-temperature and high-pressure gas in the cylinders. The expansion of the gas pushes the piston to do work, and then the mechanical work is output through the crank connecting rod mechanism to drive the driven machine to work. [0004]...
