Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a rotary piston that can be used in a prime mover, a pump, or the like.

〈Conventional technology〉 Even in the past, rotary type originals! IJ machines and pumps are being proposed one after another. In other words, the famous Wankel engine has a housing consisting of a 1~muscoid curved surface, and its inner part #
By installing a rotor consisting of 5 wires and making it perform a synthetic movement of eccentric movement and rotational movement, the volume of the space between the cylinder and the piston is changed, and this is used to generate a mixture of vaporized fuel and air. It generates power by compressing and igniting the explosion.

<Problems to be Solved by the Invention> Among the conventional rotary engines mentioned above, the Wankel engine has a relatively simple structure and is used in practical applications. In order to produce the correct shape, it is necessary to perform extremely precise machining using a special excavator, and the structure of the seal part to prevent gas leakage between the housing and rotor is extremely complex, making maintenance difficult. There are problems such as difficulty in

<Means for Solving the Problems> The present invention was made to solve the above-mentioned problems. Eight concentric rotating shafts are rotatably arranged in a cylindrical rotating cylinder, and the rotating cylinder A plurality of outer wings are provided centripetally inside the rotating shaft, and an inner wing that rotates between the outer wings is provided outside the rotating shaft, so that the rotating cylinder and the rotating shaft alternately change the rotational speed. An interlocking mechanism is provided that rotates in the same direction to change the volume of the space formed between the outer wing and the inner wing, and utilizes the change in volume of the winter space.

In addition, by utilizing the change in volume of the space formed between the outer blade and the inner blade, the high pressure and combustion gas are exhausted by compressing and igniting a mixture of vaporized fuel and air, thereby obtaining rotational force. Alternatively, high-pressure gas such as steam or compressed air, or high-pressure fluid from a hydraulic shade is supplied to the smaller volume side of the space formed between the outer wing and the inner wing to expand its volume, and Rotational force can be obtained by discharging the fluid in the space.

Furthermore, the above-mentioned rotating cylinder and rotating shaft are driven by an appropriate driving means, and the fluid is sucked from the side where the volume of the space formed between the outer blade and the inner blade increases from small to large, and the volume changes from large to small. If the fluid on the side is discharged, it can be used as a pump.

Further, the rotating cylinder and the rotating shaft are connected by a two-stage planetary gear type differential mechanism, and the M star gear mounting pedestal of the eight differential mechanism is moved in opposite directions by a driving means interlocked with the rotating shaft. It is designed to rotate back and forth.

Since the present invention has the above-described structure, a mixed gas of vaporized fuel and air is supplied to the air between the outer blade and the inner blade, and this space is reduced to reduce the mixing of vaporized fuel and air. The gas is compressed to a high pressure, and the space is rapidly expanded by means such as spontaneous ignition by adiabatic compression or ignition by electric spark. On the other hand, the volume of the adjacent space rapidly decreases, and the combustion gas generated from the explosion in the previous stroke is discharged from the exhaust port. Also, when using high-pressure steam, compressed air, or hydraulic pressure, rotational force is obtained by supplying pressure fluid to a small space in the same way as above, and discharging the fluid in the space that changes from large to small. . Furthermore, when the rotating cylinder and rotating shaft are driven with appropriate power, the volume of the space between the outer blade and the inner blade changes, so fluid is sucked into the side where the space gradually becomes larger and becomes smaller. If the fluid in the space is discharged, it can be used as a pump.

<Example> In FIG. 1, 1 is a cylindrical rotating tube.

A rotating shaft 2 is concentrically and rotatably mounted within this rotating cylinder 1. A pair of outer blades 3 are integrally fixed to the inner periphery of the rotary cylinder 1 so as to face each other.

A boss 4 is fixed to the outer periphery of the rotary shaft 2 so as to be in slidable contact with the inner end of the outer w13, and a pair of inner wings 5 are integrally formed on the outer side of the boss 4. The right end of the rotating shaft 2 is supported by a bearing at the right end of the frame 8. Further, a crankshaft 9 is rotatably mounted on the frame 8 below the shaft 2, and a gear 11 fixed to the shaft 9 and a gear 12 fixed to the shaft 2 mesh with each other and rotate in opposite directions at the same rotation speed. do.

The gear 12 has a flange, and an internal gear 14 is fixed to the left side of the gear 12. The outer periphery of the gear 14 is fixed to the flange of the gear 12, and is rotatably mounted on the shaft 2 within the gear 14 to connect to the center gear 15. The internal gear 14
A plurality of planetary gears 16 are engaged with each other.

The planetary gear 16 is rotatably attached to and detached from a planetary gear shaft 19 which is rotatably mounted on the rotating shaft 2 on the left side of the internal gear 14 and fixed to a planetary gear mounting pedestal 18. A lower end of a connecting rod 21 is rotatably connected to the crank bin 20 of the crankshaft 9.
The upper end thereof is rotatably connected to an eccentric pin 22 provided on the pedestal 18.

The left end of the crankshaft 9 is rotatably supported by a bearing at the left end of the frame 8, and a lower end of another connecting rod 24 is rotatably supported on a crank bin 23 provided symmetrically on the opposite side of the crank bin 20. The upper end of the rod 24 is rotatably connected to an eccentric pin 26 of another planetary gear mounting pedestal 25. The planetary gear mounting pedestal 25 is rotatably mounted on the rotating shaft 2, and is attached to the pedestal 2.
A planetary gear 29 is rotatably mounted on each of the plurality of planetary gear shafts 28 provided in the housing 5.

31 is a rotating shaft cylinder 32 rotatably fitted on the outside of the rotating shaft 2.
The shaft cylinder 32 is connected to the base 1 by a center gear fixed to the base 1.
8 and the pedestal 25 in a rotatable manner and is fixed to the center gear 15. Further, the planetary gear 29 is engaged with the gear 31, and furthermore, the planetary gear 29 is engaged with the internal gear 33 that is integrated with the rotating cylinder 1.

To explain the operation of the above embodiment, first, consider the central rotating shaft 2 as the input shaft, and when it is rotated in the [+] clockwise direction, the inner wing 5 at the left end, which is directly connected to this shaft 2, The gear 12 on the right side also rotates in the same manner.

At this time, assuming that the planetary gear mounting pedestal 18 is stationary, the planetary gear 16 is sandwiched and attached to the center gear 15 [-
], that is, transmits counterclockwise rotation.

(The amount of rotation does not matter at this time.) However, if the rotating shaft 2 and crankshaft 9 are interlocked by gears 12 and 11 as in the embodiment, it is impossible to rotate the rotating shaft 2 while keeping the pedestal 18 stationary. It is.

Therefore, assuming that the gear 11 does not mesh with the gear 12 and fixing the pedestal 18.25, the rotating shaft cylinder 32 and the center gear 31 will naturally rotate counterclockwise as well as the center gear 15 rotates counterclockwise. This rotation is transmitted to the internal gear 33 via the planetary gear 29 in the stationary position.
Since it rotates clockwise, internal gear 1
4.33 has the same rotation and is the same as being directly connected.

Therefore, if the shaft 2.9 is interlocked with the gear 12 and the gear 11 and each pedestal 18.25 is left free as shown in the example, the transmission from the gear 12 to the gear 11 below [-], that is,
The counterclockwise rotation rotates the crankshaft 9 in the counterclockwise direction. For this reason, the rod 21 is
Move from the current state to 90 degrees in the [+] direction, from 90 to 270 degrees (-), and from 270 to 360 degrees in the [+] direction.

However, if the shaft 19 of the planetary gear 16 is fixed as described above, the pedestal 18 will not rotate, so the pedestal 18 will be free.

When the pedestal 18 is thus freed and the rotating shaft 2 is rotated in the [+] direction as described above, the amount of rotation of the pedestal 18 is determined by the rotation radius of the crank bin 20 and the rotation radius of the bin 22 of the pedestal 18.

As a result, the rotation (angle) of the pedestal 18 from the amount (angle) that the center gear 15 rotates when the pedestal 18 is fixed to (+) (-) decreases when it is [+] and increases when it is [-]. It rotates at a slow speed like a wave. The rotation of the center gear 15 becomes the rotation of the center gear 31 which is directly connected to the outer shaft cylinder 32, and the rotation is caused by the rotation of the center gear 31 which is directly connected to the outer shaft cylinder 32.
9. It is transmitted to the rotating cylinder 1 via the internal gear 33.

At this time, the planetary gear mounting pedestal 25 is moved to the MW gear mounting pedestal 18 by the action of the crank pin 23 and the rod 24.
The crankshaft 9 performs reciprocating rotation at an N speed opposite to that of the crankshaft 9 to correct disturbances in the reciprocating rotation and also to reduce the rotation radius of the crankshaft 9.

In the above structure, when the rotating shaft 2 as an input shaft is continuously rotated in a fixed direction at a fixed speed, the rotating cylinder 1 as an output rotating body rotates in the same direction while changing the rotational speed. As a result, the space volume formed between the outer blade 3 and the inner blade 5 changes, and this change can be utilized to cause the blade to function as a prime mover or as a bomb.

For this purpose, as shown in FIGS. 2 and 3, a cylindrical stationary valve body 3 is provided on the outside of the rotary cylinder 1 integrally on the frame 8.
Surrounded by 5. As shown in FIG. 3, end walls 36 that contact the outside of the rotary cylinder 1 are integrally formed at both ends of the valve body 35, and three circumferential protrusions 37 are formed on the inside. There are four ventilation cylinders 38.

In addition, holes 39 and 40 are formed in the rotary cylinder 1 so that the front and rear roots of the outer blades 3 communicate with the ventilation cylinder 38 on the outside of the rotary cylinder 1. In addition, the interior of the six-cylinder cylinder 38 has partitions 42 and 43, respectively.
Divide into appropriate ranges. Furthermore, communication holes 45 and 46 communicating with predetermined locations of the ventilation cylinder 38 are provided in the frame 8 as shown in FIG.

In the above configuration, the communication hole 46 is communicated with a carburetor (not shown) that mixes fuel and air.
5 is connected to the exhaust pipe, the rotational speed of the outer blade 3 lags behind the outer blade 3 and the inner blade 5, which has a constant speed, so that ψ3.
5, the mixed gas is sucked into the space A from the hole 40 through the predetermined ventilation cylinder 38 and the communication hole 46 while the air A increases from the minimum to the maximum, and then the rotational speed of the outer blade 3 increases, When the air between the outer blades 3 and the inner blades 5 is at its minimum and the mixed gas is compressed, the mixed gas explodes due to the ignition of a spark plug (not shown), and the high pressure causes the outer blades 3 and the inner blades to explode. By expanding the distance between the blades 5, the outer blade 3 and the inner blade 5 continue to rotate in the same direction.

Furthermore, as the rotation progresses, the outer blade 3 catches up with the inner blade 5, and the space A gradually shrinks, and the combustion gas in the space A passes through the hole 39, a predetermined ventilation cylinder 38, and a communication hole 45 (not shown). It is discharged from the exhaust pipe. In the case of a diesel engine, as mentioned above, when the mixed gas is compressed, it is spontaneously ignited due to the high temperature caused by adiabatic compression, or only the air is compressed adiabatically.
When compressed air becomes high temperature, fuel is injected q1 to cause spontaneous ignition.

Further, if one of the communication holes 45 and 46 is used as an inlet for pressure fluid and the other is used as an outlet, it becomes a driving eye that utilizes fluid pressure. Furthermore, in the case of a pump, one of the communication holes 45 and 46 is a suction port,
The other side is used as a discharge port, and the space is expanded by driving the rotating shaft.
Suction and discharge of fluid is performed using contraction.
