Abstract

PURPOSE:To secure a conversion mechanism of both reciprocating and rotary motions, which is compact in size, lighter in weight and good in balance by passing a turning shaft through both holes at the central part of V-shaped paired surfaces, and attaching a rotor, being tilted as situated in an inner part of this V-shaped surface, to this turning shaft. CONSTITUTION:Two inclined plates 5 are set up in V-shaped form, and a hole is installed in the center, passing a shaft 1 through it, and a slant rod 4 as a rotor with the same incline as the inclined plate 5 is attached to this shaft 1 in an interval between these inclined plates 5 and 5. This slant rod 4 makes its one side be set up in a position being close and parallel with the inclined plate 5 on one side. When this slant rod 4 is rotated via the shaft 1, both ends of this rod 4 are rotated in keeping them contacted with the inclined plate 5 intact, so that it is made so as to reciprocate in the axial direction in the shape of shifting from the inclined plate 5 on one side onto the inclined plate 5 on the other, as in design. With this slant rod 4, namely, by means of reciprocation in this shaft 1, for example, a piston 3 is reciprocated, through which the suction and discharge of a fluid are carried out in this way.

2. Description of the Related Art Conventional piston engines have been based on a reciprocating engine in which a reciprocating piston is converted into a rotary motion by a crank. Despite the simple structure of the piston and good sealing performance, the method of extracting rotational motion using this crank has many restrictions, making it difficult to improve engine efficiency beyond the current level. It may be one of the causes.

[0003]

At present, the environment surrounding the engine is harsh, and there is an urgent need to improve engine efficiency. The challenge is to create a simple way to convert the linear motion of the piston into a more direct rotary motion. Its practical meaning is first of all to match the central axis of the piston with the axis of rotation taken out.

To this end, it is necessary to consider a method that is not the current method of extracting rotational motion from a piston that makes a linear motion with a crank and a connecting rod. Therefore, let us consider a method that uses some kind of elliptic motion. The challenge is to create a simple and effective mechanism that utilizes elliptical motion that combines circular and reciprocating motion.

Since the axial direction of the piston and the axial direction of the rotational movement to be taken out coincide with each other, if it is possible to construct a system for performing the rotational movement itself while the piston reciprocates, both functions are combined and very simple. The structure is created.

[0006]

As a mechanism for realizing an elliptic movement, a plate inclined with respect to the rotation axis direction is installed, and the rotation axis passes through a hole formed in the plate. An elliptical motion is performed on the plate surface around this hole. This is the first swash plate surface.

The second plate surface is installed in a V shape with respect to the first plate surface, and a hole through which the turning axis passes is formed at a position symmetrical to the hole of the first plate surface in the middle line of the V shape. Open. V-shaped lower part may be separated

A rotary shaft is passed through both holes at the center of the pair of V-shaped surfaces. An oblique rod-shaped structure is attached to this shaft inside the V-shape. The tilt angle of the rod with respect to the axis is the same as the tilt angle of the swash plate surface. The shaft can move forward and backward and rotate.
This rotating body can first be placed in a position in parallel and close contact with the first swash plate surface. When it is rotated 180 degrees, it comes into contact with the second swash plate surface in parallel. The distance between the facing swash plate surfaces is adjusted in this way. A structure protruding toward the surface is added to the end of the swash bar-shaped rotating body and a portion in contact with the slope. This is a conversion mechanism between reciprocating motion and rotary motion.

Pistons of both rods are mounted in the axial direction of this conversion engine. The stroke of the conversion engine and the piston are the same. Further, the piston shaft reciprocates, and the conversion engine shaft reciprocates while rotating. Therefore,
The mounting device is free from rotation on the piston side.

Further, the V-shaped slope and space can be formed by obliquely cutting a cylinder. Also,
The part of the swash bar structure is an elliptical plate with a cylinder having the same inclination angle. If the contact has a protruding structure, it can have a function similar to that of the swash bar. In this case, if a slant circular plate having the same inclination as the slant plate is made from a cylinder having the same diameter, these can be housed in one cylinder having the same diameter to function. In this case, the elliptical plate that moves in the V-shaped space has the function of a motion converting mechanism, the function of a rotor, and the function of a piston. The output shaft is free from reciprocating motion. In addition, intake and exhaust ports and valves are installed on both slopes.

[Action]

In the structure of the swash bar inside the V-shaped space of the motion converting engine, the inclination angle of the rod with respect to the axis is the same as the inclination angle of the swash plate surface. The shaft can move forward and backward and rotate. This swash bar rotating body can be placed in a position where it comes into close contact with the first swash plate surface in parallel, and when it is rotated 180 degrees, it comes into close contact with the second swash plate surface in parallel. . The distance between the swash plate surfaces facing each other is adjusted in this manner, and the swash bar-shaped tip and the portion in contact with the sloping surface are provided with a structure protruding toward the surface so that the swash plate surfaces are in better contact with each other. This is based on the fact that both ends of the swash bar rotate in the axial direction and the distance is the same because the slope angles of both slopes are the same. Therefore, the swash bar rotates forward while always contacting both sides, and then rotates backward. It rotates when it reciprocates and reciprocates when it revolves, and acts as an effective motion conversion mechanism for reciprocating motion and rotating motion.

If the pistons of both rods are mounted in the axial direction of the conversion engine and the strokes of the conversion engine and the piston are the same, the piston shaft reciprocates, and the conversion engine shaft reciprocates while rotating. Exercise. At this time, since the coupling device between the piston and the converter is free from rotation on the piston side, the swash bar makes a reciprocating motion while performing a rotary motion.

Further, if the V-shaped slope and space are formed by obliquely cutting a cylinder, and if the portion of the swash bar structure is an elliptical plate shape in which the cylinder is cut at the same inclination angle, the contact points are formed. If there is a protruding structure of this, this elliptical plate can have the same function as the swash bar rotating body, so in this case, if they are considered as cylinders of the same diameter, these are placed inside one cylinder of the same diameter. It can be stored and functioned. In this case, the elliptical plate is provided with a function of a motion conversion mechanism, a rotor and a piston in a V-shaped space. The output shaft is free from reciprocating movement, and intake and exhaust ports and valves are installed on both slopes.

[0015]

[Embodiment] If the projection for making contact with the slope of the swash bar has a spherical surface or a structure having the same effect as the spherical surface, for example, if the contact surface is a shape where the head swings around one point, this tip Always moves in contact with the surface, and the reciprocating motion and the rotary motion are very smoothly interlocked with each other, and it works as an effective motion conversion engine. As one example, the piston is reciprocated by the rotational movement of the motor to operate as a compressor.

Compressed air or other pressure fluid is alternately put into the pistons of both rods to cause reciprocating motion, and the rotary motion is taken out by the combined motion converting mechanism.

A rotating piston having a motion converting mechanism and a piston function integrated is rotated by a motor to operate as a compressor.

Rotational motion is taken out by alternately inserting compressed air into a rotary piston in which a motion converting mechanism and a piston function are integrated.

[0019]

As compared with the conventional crank system, the mechanism for converting reciprocating motion and rotary motion of the present invention has the cylinder axis of the piston and the direction of the rotary axis aligned with each other, and the arrangement of all functional parts is shortened. , Becomes extremely compact.

The swash bar structure, which is the rotating part, is well balanced and lighter than the crank and connecting rod type.

The torque applied to the rotary motion is averaged and efficiency is improved as compared with the crank system.

In the case of a rotary piston in which the motion conversion engine and the piston function are integrated, the structure becomes much more compact. These produce a positive effect that is much greater than some negative effect, such as on the rotation of the piston and the separation of linear and rotational movements on the shaft.
