Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the principle of a prime mover.

[0002]

2. Description of the Related Art Currently, prime movers used in automobiles include reciprocating engines, rotary engines and turbine engines. A reciprocating engine is a prime mover characterized by reciprocating piston movement. However, since the center of gravity moves largely with the reciprocating motion of the piston, there are drawbacks that vibration is large and energy efficiency is not good. A rotary engine is a prime mover characterized in that a rice ball-shaped rotor makes a rotary motion while making an elliptical motion. However, even in this prime mover, the center of gravity of the rotor has an elliptic motion, and therefore, there is a drawback that a considerable amount of vibration occurs. On the other hand, the turbine engine is a prime mover in which the compression and explosion strokes are arranged in parallel, and since it is a motion centered on the rotating shaft, there is no movement of the center of gravity, and therefore, there is an advantage that the vibration is small and the rotation speed can be increased. However, since the turbine pump is used in the compression process, a sufficient engine output cannot be obtained unless the engine speed reaches a high level.

[0003]

[Problems to be Solved] Therefore, there has been no principle of a prime mover in which the center of gravity does not move along with the stroke and the engine output is obtained from a low rotation speed. The present invention provides a new prime mover principle that can solve these problems.

[0004]

[Means for Solving the Problems] In order to solve the problems,
Invented a principle of a new prime mover characterized in that a movable member installed in a housing having an inner surface shape that surrounds a range of motion of the movable member simultaneously performs rotary motion while performing rocking motion or motion similar to rocking. .

[0005]

The mixture of fuel and air is sucked into the space formed by the movable member and the housing in accordance with the swinging motion of the movable member or the motion similar to the swinging and the rotating motion, and the space becomes smaller. It is compressed and explodes as its space grows and then shrinks. Since this series of processes is performed in association with the swinging movement of the movable member or the movement similar to the swinging and the rotating movement, the center of gravity does not move, and high rotation is not required to compress the air-fuel mixture.

[0006]

【Example】

(A) Example 1 The movable member has a concentric circle with a phase difference of 120 degrees.
A corrugated disc 1 having corrugated irregularities is used. The wavy disc 1 performs an oscillating motion with the center of rotation as a fulcrum, and rotates at an angular velocity of one third of the oscillating motion. In this case, the angular velocity of the oscillating motion is a circle seen when the central axis of the wavy disc 1 is a flat disc without wavy irregularities and when the center axis of the disc is precessed. It refers to the traveling angular velocity of a traveling wave-like motion (swing motion) around a plate (that is, the angular velocity of precession motion). The wavy disc 1 is installed in a housing 2 having an inner surface shape surrounding the movement range of the wavy disc 1. At this time, the inner surface of the housing 2 is concentric with a phase difference of 180 degrees. The shape has wavy irregularities at some places. The housing 2 is provided with an intake port 3, an exhaust port 4 and an ignition device 5. The wavy disc 1 has a universal joint mechanism 6 at the center of rotation, and the universal joint mechanism 6 swingably connects the wavy disc 1 and the rotary shaft 7 with a free ring 9 and a pin 10. Rotating shaft 7
Is rotatably supported at the center of the housing. The outer periphery of the wavy disc 1 contacts the inner peripheral wall of the housing 2, and the convex portion of the wavy disc 1 linearly contacts the inner surface of the housing 2,
Since the wavy disc side of the universal joint mechanism 6 contacts the inside of the housing, a space is formed between the wavy disc 1 and the housing 2, and this space becomes the engine room 8. In this embodiment, the engine rooms 8 are formed on both upper and lower surfaces of the wavy disc 1. In order to clearly show the processes of intake, compression, explosion, and exhaust, the concentric circular cross-section 11 is cut off along the line AA ′ from the rotary shaft and expanded into a plane in FIGS. Each figure has three wavy discs 1.
The case where the wavy disc 1 is rotated by 0 degrees is shown in order, and the wavy disc 1 is shown to rotate such that the circumferential cross section of the wavy disc 1 moves from left to right. The positions of the intake port, the exhaust port and the ignition device are indicated by dotted circles 12, 13, 14 respectively.
It is indicated by. Further, the wavy dotted line 15 indicates the circumference of a flat disc on the assumption that the wavy disc 1 has no wavy irregularities, and represents the progress of the swinging motion of the wavy disc 1 as described above.
The engine room formed by the wavy disc 1 and the housing 2 is formed at a total of 6 positions above and below the wavy disc 1. Now, focusing on one of them 16, the wavy disc 1 is located from the position of FIG. The mixture of fuel and air is sucked into one of the engine rooms 16 from the intake port until it rotates 90 degrees (FIGS. 5, 6, 7, and 8). Along with this, the oscillating motion of the wavy disc advances by 270 degrees. The next 90 ° rotation of the wavy disc compresses the aspirated mixture (FIGS. 8, 9, 1).
0, 11). Along with this, the oscillating motion of the wavy disc further advances by 270 degrees. When the air-fuel mixture is ignited 17 here, a rotational force is applied to the wavy disc due to the explosion, and the wavy disc further rotates 90 degrees (FIGS. 11, 12, 13, and 14). Along with this, the oscillating motion of the wavy disc further advances by 270 degrees. Exhaust gas is exhausted from the exhaust port with the next 90 degree rotation of the wavy disc (FIGS. 14, 15, 16, 5). Along with this, the oscillating motion of the wavy disc further advances by 270 degrees. By repeating this cycle, the engine output can be taken out from the rotating shaft. In addition, since there are a total of 6 engine rooms above and below the wavy disc, the wavy disc is 360
It is a mechanism in which six explosions are obtained while rotating once, and the rotational force is constantly applied to the wavy disc 1. (B) Embodiment In Example 1, as the movable member, a wavy disc having concentric circles with a phase difference of 120 degrees and three wavy irregularities was used, but the wavy disc does not necessarily have to be wavy. Any form may be used as long as it makes smooth contact with the housing at three points on one side. Further, in Example 1, the number of the irregularities of the wavy disc was three, but it may be any number as long as it is two or more. At this time, the unevenness of the inner surface of the housing is 1 from the number of unevenness of the wavy disc.
It must be the number minus. The unevenness of the inner surface of the housing is wavy like the movable member in the first embodiment, but it is not necessarily wavy and may be smooth unevenness.
It may also be triangular or the like. However, since the swinging motion of the movable member is somewhat jerky except for the wavy form, the motion is similar to the swinging motion, but in principle there is no change. In the first embodiment, the mixture of fuel and air is compressed and exploded, but a method of compressing only air and injecting fuel to explode may be used. Further, although the prime mover as the internal combustion engine is shown in the first embodiment, it may be used as an external combustion engine.

[0007]

According to the present invention, it is possible to provide a prime mover in which the center of gravity does not move during a stroke and an engine output can be obtained from a low rotation speed.

2. Description of the Related Art Currently, prime movers used in automobiles include reciprocating engines, rotary engines and turbine engines. A reciprocating engine is a prime mover characterized by reciprocating piston movement. However, since the center of gravity moves with the reciprocating motion of the piston, the vibration is large, and the crank machine converts the reciprocating motion into the rotary motion.
Since it requires a structure, there is a drawback that mechanical loss is large . The rotary engine has a rice ball type rotor.
It is a prime mover characterized by making a rotary motion . However, even in this prime mover, the center of gravity of the rotor has an eccentric rotational motion, and thus there is a drawback in that vibration is generated to some extent. On the other hand, the turbine engine is a prime mover in which the compression and explosion strokes are arranged in parallel, and since it is a motion centered on the rotating shaft, there is no movement of the center of gravity, and therefore, there is an advantage that the vibration is small and the rotation speed can be increased.

Embodiment (a) Embodiment 1 The movable member is formed with a convex portion in a concentric pattern with a phase difference of 120 degrees.
The wavy disc 1 having wavy unevenness is used. The wavy disc 1 is supposed to rotate at an angular velocity that is one third of the swinging motion while performing the swinging motion with the center as a fulcrum .
Incidentally, the angular velocity of the swing motion, if the corrugated disc 1 is wavy unevenness is assumed to be no flat disc, the central axis of the discs, the precession center of the disc as a fulcrum It refers to the advancing angular velocity of the wavy motion (oscillating motion) around the disk when observed (that is, the angular velocity of precession motion). Wavy disc 1
Is installed in a housing 2 having an inner surface shape that surrounds the movement range of the wavy disc 1. The inner surface of the housing 2 at this time forms a convex portion concentrically with a phase difference of 180 degrees.
The shape should have smooth irregularities . Housing 2
An intake port 3, an exhaust port 4 and an ignition device 5 are provided in the. The wavy disc 1 has a universal joint mechanism 6 at the center of rotation, and the universal joint mechanism 6 swingably connects the wavy disc and the rotary shaft 7 with a free ring 9 and a pin 10. The rotating shaft 7 is rotatably supported at the center of the housing. The outer periphery of the wavy disc 1 is in contact with the inner peripheral wall of the housing 2, and the convex portion of the wavy disc 1 is the housing 2
Since the wavy disc side of the universal joint mechanism 6 comes into contact with the inside of the housing, a space is formed between the recess of the wavy disc 1 and the housing 2.
This space becomes the engine room 8. In this embodiment, a total of 6 engine rooms are formed on the upper and lower surfaces of the wavy disc 1. In order to illustrate the process of intake, compression, explosion, and exhaust in an easy-to-understand manner, a concentric circular cross section from the rotation axis 11
Fig. 5-16 shows the result of cutting off at A-A 'and developing it on a plane.
Is. Each of the figures sequentially illustrates the case where the wavy disc 1 is rotated by 30 degrees, and the wavy disc 1 is rotated so that the circumferential cross section of the wavy disc 1 moves from left to right. ing. The positions of the intake port, the exhaust port and the igniter are indicated by dotted circles i2, 13, 14 respectively.
Further, the wavy dotted line 15 indicates the circumference of a flat disc on the assumption that the wavy disc 1 has no wavy irregularities, and represents the progress of the swinging motion of the wavy disc 1 as described above. The engine room formed by the wavy disc 1 and the housing 2 is formed in a total of 6 places above and below the wavy disc 1. Now, one of them is
Focusing on 6, the mixture of fuel and air is sucked from the intake port to one of the engine rooms 16 until the wavy disc 1 rotates 90 degrees from the position of FIG. 5 (FIG. 5,
6, 7, 8). As a result, the swinging motion of the wavy disc is 27
Progress 0 degrees. At the next 90 ° rotation of the wavy disc, the aspirated mixture is compressed (FIGS. 8, 9, 10, 11). Along with this, the oscillating motion of the wavy disc further advances by 270 degrees. When the air-fuel mixture is ignited 17 (Fig. 11), a rotational force is applied to the wavy disc due to the explosion, and the wavy disc is further rotated by 9
It rotates 0 degrees (FIGS. 11, 12, 13, and 14). Along with this, the oscillating motion of the wavy disc further advances by 270 degrees. Exhaust gas is exhausted from the exhaust port with the next 90 degree rotation of the wavy disc (FIGS. 14, 15, 16, 5). Along with this, the oscillating motion of the wavy disc further advances by 270 degrees. The rotation force is supplied to the rotating shaft 7 by repeating this cycle.
To be done . Also, because there are a total of 6 engine rooms above and below the wavy disc, 6 explosions are obtained while the wavy disc rotates 360 degrees, and the wavy disc 1 is constantly given a rotational force. Is. (B) Embodiment In Example 1, as the movable member, a corrugated circular plate having a convex portion with a phase difference of 120 degrees concentrically was used.
It does not have to be a wavy disc , but a disc or the center of the disc
If it has a cone-like shape with raised parts and can rotate while smoothly contacting the housing at three points on one side,
Good . In addition, as apparent from the first embodiment, basically, the wave
The engine can be configured if there is one side of the circular disk. further,
In Example 1, since the convex portions are formed concentrically with a phase difference of 120 degrees, the convex portion of the wavy disc has three positions on one side.
In reality, an engine can be configured if there are two or more convex portions on one side with concentric circles and the same phase difference. At this time, when the number of convex portions on one side of the wavy disc is n, the phase difference of the convex portions is 360 / n.
The rotation angular velocity of the wavy disc must be 1 / n of the angular velocity of the swinging motion. Further, the phase difference of the convex portion on the inner surface of the housing is 360 degrees of n-1 / 360. However, when n is 2, it simply functions as a compressor, and thus a valve mechanism like a reciprocating engine is required to configure the engine. When n is 3 or more, the valve mechanism is not necessary, but n
Is 4 or more, an invalid space is constructed. Of movable members
Although the shape of the housing surface facing the convex portion is wavy like the movable member in the first embodiment, it is not necessarily wavy and may be smooth unevenness according to the shape of the movable member . However, although the swinging motion of the movable member outside the wave shape somewhat jerky, no where no change in principle manner. In the first embodiment, the movable member performs passive movement,
In order to actively move the movable member, the rotary shaft 7

A reduction gear mechanism and an oscillating crank mechanism are required. Also,
To completely seal the movable member and the housing,
It is also necessary to install a ruler member. In the first embodiment, the mixture of fuel and air is compressed and exploded, but a method of compressing only air and injecting fuel to explode may be used.
Further, although the prime mover as the internal combustion engine is shown in the first embodiment, it may be used as an external combustion engine.
