Description

Technical Field

[0001] The present invention relates to a mechanical transmission mechanism for converting the reciprocating linear motion of a piston into the circular motion of a crankshaft, and in particular to a transmission mechanism based on a slideway, a gear and a rack to replace the existing crankshaft (handle) - connecting rod transmission mechanism. Background Art

[0002] At present, piston internal combustion engines (engines) generally use crankshaft-connecting rod mechanisms to convert the reciprocating linear motion of the piston into circular motion. However, the crankshaft-connecting rod mechanism still has some difficult-to-overcome defects, which need to be further improved and optimized:

[0003] 1. In the traditional crankshaft connecting rod mechanism, the force on the piston can be converted into the tangential force driving the crankshaft crank to rotate after multiple decompositions. Theoretical analysis and practical application tests show that only about 20% of the maximum force acting on the piston is decomposed into the tangential force driving the crankshaft crank to rotate, that is, only about one-fifth of the maximum force drives the crankshaft to output the maximum torque. Conversely, only about one-fifth of the maximum rotational inertia force of the crankshaft is converted into the force driving the reciprocating motion of the piston. Therefore, when the traditional crankshaft connecting rod mechanism converts the reciprocating linear motion of the piston into circular motion, the power output efficiency is very low and the mechanical transmission efficiency is also low;

[0004] 2. In the traditional crankshaft (handle) connecting rod mechanism, the force on the piston is decomposed into the force along the connecting rod axis and the lateral pressure acting on the cylinder wall. The lateral pressure acting on the cylinder wall increases the lateral friction between the piston and the cylinder wall, accelerates the lateral wear of the cylinder wall, causes "cylinder jamming", makes the piston unable to work, and shortens the service life of the cylinder;

[0005] 3. The unbalanced rotating mass and rotating motion generated by the swing of the connecting rod in the traditional crankshaft connecting rod mechanism cause the transmission mechanism to produce alternating impact force, increasing the uneven friction and impact between the various components, which not only affects the output power of the engine, but also causes the engine to produce greater vibration and noise.

[0045] The operation process of the first embodiment of the present invention is as follows:

[0046] The first step, such as Figure 7 As shown, when the guide cylinder 103 on the rotating arm 102 enters from the B opening end 304' of the guide slot 3 and slides clockwise to the middle of the guide slot 3, the piston 5 connected to the connecting rod 202 at one end of the A rack 2 and the B rack 2' and the piston 5 connected to the connecting rod 403 on one side of the A driving beam 4 and the B driving beam 4' move to the top dead center, while the piston 5 connected to the connecting rod 202 at the other end of the A rack 2 and the B rack 2' and the piston 5 connected to the connecting rod 403 on the other side of the A driving beam 4 and the B driving beam 4' move to the bottom dead center.

The gas explosion force acting on the corresponding pistons 5 drives the main shaft 1 to rotate clockwise with the help of the A driving beam 4, the B driving beam 4', the A rack 2, the B rack 2' and the guide slot 3 as well as the sector gear 101, and the four pistons 5 at the top dead center begin to move toward the bottom dead center, and the four pistons 5 at the bottom dead center begin to move toward the top dead center.

[0048] The third step is Fig. 9 As shown, when the sector gear 101 is disengaged from the A rack 2, the guide cylinder 103 on the rotating arm 102 slides into the guide slot 3 from the A opening end 304 of the guide slot 3, and the four pistons 5 moving from the top dead center to the bottom dead center are about to reach the bottom dead center, and the four pistons 5 moving from the bottom dead center to the top dead center are about to reach the top dead center.

[0050] Step 5: Fig.10 As shown, the main shaft 1 and its sector gear 101 drive the rotating arm 102 to continue to rotate clockwise under the action of the rotational inertia force couple, and the guide cylinder 103 on the rotating arm 102 slides out from the B opening end 304' of the guide slot 3, the sector gear 101 and the B rack 2' begin to mesh, and the gas in the cylinder 6 where the four pistons 5 at the top dead center are located explodes, and the gas explosion force acting on the corresponding piston 5 pushes the piston 5 to move to the bottom dead center, and with the help of the A driving beam 4, the B driving beam 4', the A rack 2 and the B rack 2', the guide slot 3 and the sector gear 101, the main shaft 1 continues to rotate clockwise, and the four pistons 5 at the bottom dead center begin to move toward the top dead center.

[0051] Step 6: Fig.11 As shown, when the sector gear 101 is disengaged from the B rack 2', the guide cylinder 103 on the rotating arm 102 slides into the guide slot 3 from the B opening end 304' of the guide slot 3, and the four pistons 5 moving toward the upper dead center are about to reach the upper dead center, and the four pistons 5 moving toward the lower dead center are about to reach the lower dead center.

[0052] Step 7: Figure 7 As shown, the guide cylinder 103 on the rotating arm 102 slides clockwise again to the middle position of the guide slide groove 3, and the piston 5 connected to the connecting rod 202 at one end of the A rack 2 and the B rack 2' and the piston 5 connected to the connecting rod 403 on one side of the A driving beam 4 and the B driving beam 4' move to the top dead center again, and the piston 5 connected to the connecting rod 202 at the other end of the A rack 2 and the B rack 2' and the piston 5 connected to the connecting rod 403 on the other side of the A driving beam 4 and the B driving beam 4' move to the bottom dead center again. The various moving parts of the transmission mechanism based on the slide groove-gear and rack of the present invention repeat the above-mentioned operation process from the first step to the sixth step over and over again, converting the reciprocating linear motion of the piston 5 into the rotation of the main shaft 1.

[0053] The second embodiment of the present invention is different from the first embodiment in that:

[0054] like Fig.12 As shown, the two sides of the A driving beam 4 and the B driving beam 4' can be extended to connect multiple groups of connecting rods 403, and each connecting rod 403 is connected to the piston 5 in the corresponding cylinder body 6 on the housing 7 to form an opposed multi-cylinder engine group.

[0055] The operation process of the second embodiment of the present invention is the same as the operation process of the first embodiment of the present invention.

[0056] The third embodiment of the present invention is different from the first embodiment in that:

[0057] like Fig.13 As shown, the main shaft 1 is connected to the motor 8, and each cylinder 6 is a compression cylinder of a reciprocating compressor 9 or a high-pressure pump 10, that is, a unit of multiple compressors 9 or a unit of multiple high-pressure pumps 10 driven by one main shaft 1 is formed.

[0058] The operation process of the third embodiment of the present invention is opposite to the operation process of the first embodiment of the present invention.

[0059] The above implementation modes of the transmission mechanism of the present invention do not limit the practical scope of the transmission mechanism of the present invention. Without departing from the design of the present invention, engineers and technicians in this field may make various modifications and improvements to the technical solution of the present invention, which should all fall within the protection scope determined by the claims of the present invention.
