Description

  The present invention relates to a rotating machine that can function as a pump, an engine, an actuator, or the like.

For a rotary machine that operates using external power, or for a rotary machine that outputs power by injecting working fluid or fuel, for example, a pump / motor or actuator using eccentric operation, or rotational power from reciprocating piston motion. Engines that take out slag are widely known. These rotating machines are well known without needing to be specifically illustrated.

  However, these conventional pumps, engines, actuators, etc. have energy loss due to the discrepancy between the center of rotation and the center of gravity of the rotating part due to the reciprocating movement of the piston or the eccentricity of the cylinder block, and the vibration and noise generated due to this are large. There was a problem.

In addition, there are pumps with a structure that is not eccentric, but this type is typically hermetically sealed because the rotor rotates in the housing with or without linear contact with the inner wall of the housing. It is not suitable for high-pressure pumps and engines because it has poor performance and has been increased in size and rotation to compensate for it.

The present invention has been made paying attention to these problems, and eliminates the disadvantages of conventional rotating machines, and has a structure that enables high efficiency, low vibration, low noise, and high-speed rotation like an electric motor. An object is to realize a rotating machine and to make effective use of the rotating machine as a pump, an engine, an actuator, or the like.

  In order to achieve the above object, the present invention takes the following measures.

That is, the rotating machine of the present invention has two rotating parts, and a part of the fan shape is a fan shape, and the fan shape of the rotating part rotates at right angles to each other with the virtual center point of the spherical surface of the shape as the same center. Rotate in time so that it doesn't hit the surface. At that time, one rotating part is supported from the smaller spherical side of the sector, and the other rotating part is supported from the larger spherical side of the sector, so that the supporting part and the rotation path cover are supported. The closed region formed by the rotating part and the two rotating parts has a structure that changes as the rotating part rotates.

If comprised in this way, one rotation part will become the form which closes the front and back of the rotation path of another rotation part in the part which a rotation path cross | intersects during rotation. Since the periphery of the rotation path is closed by the cover part and the support part of the rotation part, the closed area in front of the rotation part becomes narrower with rotation, and the closed area behind the rotation part becomes wider with rotation. Therefore, if a hole is made near the intersecting portion of the rotation path of the cover portion, it functions as a pump and an actuator.

  As a result, the movable part can be structured not to reciprocate or eccentrically rotate, so that the problems of vibration and noise can be effectively solved, and the rotating part and the rotating path are in surface contact over a wide range. Alternatively, since it can be brought close to a state close to this, the airtightness can be remarkably improved, and a rotating machine that operates with high efficiency even with a small size and low rotation can be achieved.

  Specifically, two rotating parts having a substantially fan-shaped side surface and a partially spherical shape having the same virtual center point on the outer peripheral surface and the inner peripheral surface are perpendicular to each other around the virtual center point. In order not to interfere with each other, it is configured to rotate synchronously at the same timing. In that case, one rotating part has a supporting part on the inner peripheral surface side, and the other rotating part has a supporting part on the outer peripheral surface side, and a cover part is provided at a position covering the rotation path together with the supporting part. Rotating each other's rotating part in a manner that obstructs the rotation path of the other rotating part at the crossing part, so that the supporting part, the cover part, the side face of the rotating part, and the other rotation The space closed by the end face of the part is adapted to expand and contract with the rotation of both rotating parts.

In this case, in order to prevent vibration and noise, one support portion has a spherical surface having the same virtual center as the inner peripheral surface of the rotating portion and is extended from the position in contact with the inner peripheral surface in the direction of the arc of the fan. The support part has a shape in which a spherical surface having the same virtual center as that of the outer peripheral surface of the rotating part is expanded from the position in contact with the outer peripheral surface in the direction of the arc of the fan. It is useful to make the center of gravity of the movable part made up of parts coincide with each other.

In order to associate this rotating machine with the power transmission system, the two support parts are connected by an interlocking mechanism such as a gear, and the timing of rotation of both rotating parts is matched by this interlocking mechanism, and the rotating part is connected via the interlocking mechanism. It is preferable that the rotation force is input to and the rotation force is output from the rotation unit.

In order for this rotating machine to function as a pump, motor, or actuator, a hole that opens in a closed space is provided in the cover part, and a hole that opens in the expansion area when the space changes due to rotation of the rotating part. A fluid path may be connected to each hole so as to form a suction port or a high-pressure port, and a hole opening in the reduced region becomes a discharge port or a drain port, and a power transmission system may be configured. Various fluids such as water, air, and oil can be used as the fluid.

In addition, in order for this rotating machine to function as an engine, a hole that opens in a closed space is provided in the cover part, and two rotation paths are connected at a place other than the crossing part using a part of the hole. By providing a connecting part that compresses the mixed gas that is confined in one rotation path and introduced into the space in the contracting process, the mixed gas is closed in the other rotating path through the connection part and expanded In this case, the exhaust gas is introduced into the space, and after the explosion and expansion, the exhaust cycle is continuously operated.

As described above, according to the present invention, since the rotating part and the supporting part, which are movable parts, can have a rotating structure that hardly generates inertial resistance during operation, vibration and noise can be reduced, and rotation that can withstand high rotations. A machine, a pump / motor, an actuator, and an engine using the machine can be realized. In addition, since high airtightness can be maintained between the rotating part and the rotating path, it can be used as a rotating machine or the like with less energy loss as compared with a conventional non-eccentric type.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

The rotating machine of this embodiment interferes with two rotating parts 1 (1a, 1b) indicated by solid lines in FIG. 1 along rotating paths 5a, 5b provided on rotating surfaces orthogonal to each other indicated by imaginary lines in FIG. It is made to rotate synchronously without doing. The rotation paths 5a and 5b are partially covered by the cover portion 2 shown in FIGS. 2 and 6, and the rotation portions 1a and 1b are backed up by the support portions 4 and 3 shown in FIGS. 5b. In this state, the movable part composed of the rotating part 1a and the support part 4 rotates with the rotation path 5a closed, and the movable part composed of the rotation part 1b and the support part 3 rotates with the rotation path 5b closed. Make a structure. FIG. 7 is an exploded view showing the assembly relationship between the rotating part and the cover part.

More specifically, the outer periphery 11 and the inner periphery 12 of the rotating part 1 (1a, 1b) are spherical surfaces having the same virtual center point O, and the side surface 13 is the center of the spherical surface from the outer periphery 11 to the inner periphery 12 as the spherical surface. That is, it is formed by a curved surface formed by a collection of lines toward the same virtual center point O. This curved surface is a conical surface. In this specification, the shape of the side surface of the rotating portion 1 is referred to as a “fan shape”. However, as clearly shown in FIG. 1 and the like, the side surface formed by the outer periphery 11 and the inner periphery 12 and an end surface 14 described later. It is a partial annular view. In addition, the terms “fan” and “fan” have the same meaning.

The rotating part 1 is sized to fit in a region slightly smaller than 180 ° in the rotation paths 5a and 5b, that is, in a region that does not cover the intersection of the rotation paths 5a and 5b (fan angle is about 150 °). The shape of the front and rear end faces 14 in the rotational direction is not particularly limited. Even if it does in this way, it is because the basic function is the same, only airtightness is lost at a certain rotational position. An example in which the rotating unit 1 occupies a region of approximately 180 ° in the rotation paths 5a and 5b will be described later.

  3 to 5 show a state in which the rotating parts 1a and 1b are supported by the supporting parts 4 and 3. FIG. In each figure, the portions indicated by reference numerals 31 and 41 are spherical support surfaces having the same virtual center O as the outer peripheral surface 11 and the inner peripheral surface 12 of the rotating portion 1 having a fan shape, and these support portions 3 and 4 are fan-shaped. The outer peripheral side arc or the inner peripheral side arc of the rotating unit 1 forming the shape is expanded from a position where it is backed up to a circular shape. Of the support portions 3 and 4, the shape of the other portions excluding the support surfaces 31 and 41 is arbitrary, the length of the arc of the fan-shaped portion of the rotating portion 1 and the width in the direction perpendicular to the paper surface in FIGS. In addition, the diameters of the spherical surfaces constituting the outer peripheral surface 11 and the inner peripheral surface 12 can be freely determined.

2, 6, and 7, the cover outer wall 22 that closes the outer peripheral side of the vertical rotation path 5 a in the drawing and the inner peripheral side of the horizontal rotation path 5 b in the drawing are closed. The cover inner wall 21 is formed of a spherical surface having the same virtual center point O, and the cover side walls 23, 24, 25, 26 covering the upper and lower sides of the rotation path 5b and the cover side walls 27a, 27b, 28a, 28b covering the left and right of the rotation path 5a are the same. It is close to a semicircle formed by a curved surface formed by a collection of lines toward the virtual center point O. These curved surfaces are also conical surfaces corresponding to the shape of the side surface 13 of the rotating portions 1b and 1a.

  The rotating portion 1 (1a) of FIGS. 1, 4, 5 and 7 is also provided in the longitudinal rotation path 5a of the cover portion 2 shown in FIGS. 2, 6 and 7, and FIGS. 1, 3, 5, and 7 are accommodated in the horizontal rotation path 5 b of the cover portion 2 shown in FIG. The rotating part 1 (1a) constitutes a movable part together with the support part 4, and the rotating part 1 (1b) constitutes a movable part together with the support part 3, and these movable parts are located at the virtual center point O with respect to the cover part 2. Rotate around.

As described above, the side surfaces of the rotating portion 1 (1a, 1b) are covered by the cover side walls 23, 24, 25, 26, 27a, 27b, 28a, 28b at the portions other than the crossing portions of the rotating paths 5a, 5b. The outer peripheral surface 11 of the rotating part 1a arranged in the vertical rotation path 5a is covered at two locations in the upper and lower portions by a partial spherical cover outer wall 22 at a portion excluding the intersection of the rotation paths 5a and 5b. The inner peripheral surface 12 of the rotating part 1b arranged in the rotation path 5b is covered at two places on the left and right sides by a partially spherical cover inner wall 21 at a portion excluding the intersection of the rotation paths 5a and 5b.

And the inner peripheral side of the rotation path 5a is closed by the annular support part 4 that supports the inside of the rotation part 1a including the crossing part of both rotation paths 5a, 5b, and the outer periphery side of the rotation path 5b is both rotation paths 5a, The structure is closed by an annular support portion 3 that supports the outside of the rotating portion 1b including the crossing portion 5b.

At this time, the shape of the portion of the cover portion 2 in contact with the movable portion consisting of the rotating portion 1a and the support portion 4 and the shape of the portion in contact with the movable portion consisting of the rotating portion 1b and the support portion 3 are determined as follows. When it rotates, it always slides in close contact with each part of the cover part 2 so that airtightness is maintained.

Then, holes are provided at appropriate locations in the cover portion 2 and these are used as input / output ports to function as pumps and actuators.

As shown in FIG. 6, there are two holes (P1, P2, P3, P4) on the cover outer wall 22 of the vertical rotation path 5a in the vicinity of each crossing portion, as shown in FIG. Two locations (P5, P6, P7, P8) are provided on the inner wall of the cover of the rotation path 5b, for a total of 8 locations.

Next, the operation of this rotating machine will be briefly described. For example, the system is in the rotating state of FIG. 8, and at each crossing portion of the rotation paths 5a and 5b, the rotation section 1a (1b) moves forward and rearward of the rotation path 5b (5a) of the other rotation section 1b (1a). In the closed form, the closed area Sb1 (Sa1) between the front of the rotating part 1b (1a) and the side surface of the rotating part 1a (1b) becomes narrower with the rotation, and the rear part of the rotating part 1b (1a) and the rotation. The closed region Sb2 (Sa2) between the side surfaces of the portion 1a (1b) becomes wider with rotation. Therefore, in this figure, P1 and P8 are inflow ports, and P2 and P7 are outflow ports. Alternatively, the system is in the rotation state of FIG. 9 that is 180 ° out of phase with respect to FIG. 8, and the rotation unit 1a (1b) is the other rotation unit 1b (1a) at each intersection of the rotation paths 5a and 5b. When the front and rear of the rotation path 5b (5a) are closed, the closed region Sb3 (Sa3) between the front of the rotation unit 1b (1a) and the side surface of the rotation unit 1a (1b) becomes narrow with rotation. Thus, the closed region Sb4 (Sa4) between the rear of the rotating part 1b (1a) and the side surface of the rotating part 1a (1b) becomes wider with rotation. Therefore, in this figure, P4 and P6 are inflow ports, and P3 and P5 are outflow ports.

FIGS. 10 to 19 show the rotation paths 5a and 5b further expanded and graduated every 30 °. The right shoulder of each figure shows how many rotating parts 1a and 1b are in the state of FIG. It is rotated or its phase difference is noted. The state of FIG. 13 substantially corresponds to FIG. 8, and the state of FIG. 17 substantially corresponds to FIG. It is assumed that a flow path (not shown) is connected to each of the ports P1 to P8, and appropriate supply / discharge valves are provided in the flow paths.

The state of FIG. 10 shows the moment when the front ends of both rotating parts 1a and 1b enter the crossing part. In this state, of the eight ports P1 to P8, the four ports P1, P3, P5, and P8 are all “closed”, and the remaining four ports P2, P4, P6, and P7 are “open”. Become. Before and after this, the crossing portions of the rotation paths 5a and 5b are not blocked, so that expansion / contraction in a confined state of the space does not occur. However, it is necessary to close the supply / discharge valves of the ports P1 to P8.

In the state of FIG. 11 in which the phase is advanced by 15 ° from FIG. 10, the ports P1 and P8 are switched from closed to open, the ports P3 and P5 are still “closed”, and the ports P2, P4, P6 and P7 are still “open”. is there. Even before and after this, the crossing portions 5a and 5b of the rotation path are not blocked, and expansion / contraction in a confined state of the space does not occur. During this time, it is necessary to close the supply / discharge valves of the ports P1 to P8 as in the state of FIG.

In FIG. 12, in which the phase is advanced by 30 ° from FIG. 10, the states of the ports P1 to P8 are the same as those in FIG. 11, but at this stage, the crossing portions of the rotation paths 5a and 5b are completely blocked by both rotation portions 1a and 1b. Is done. For this reason, the regions Sa2 and Sb2 are confined from this position and expansion is started, and the supply and discharge valves of the ports P1 and P8 that open to these portions are opened. Thereby, the fluid flows into the regions Sa2 and Sb2 via the ports P1 and P8.

In the state of FIG. 13 in which the phase is advanced by 60 ° from FIG. 10, the ports P4 and P6 are “closed”. For this reason, the regions Sa1 and Sb1 are confined from a position slightly ahead, and the reduction starts, and the supply and discharge valves of the ports P2 and P7 that open to these portions are opened. Thereby, the fluid in the regions Sa1 and Sb1 flows out through the ports P2 and P7.

The state of FIG. 14 in which the phase is advanced by 150 ° from FIG. 10 is the moment when the rear of both rotating parts 1a and 1b starts to exit from the intersection of both rotating paths 1a and 1b, and the ports P3 and P5 are closed to open. Thus, the expansion in the closed state of the areas Sa2 and Sb2 is completed. For this reason, the ports P1, P3, P5, and P8 that open to these portions are closed.

The state of FIG. 15 in which the phase is advanced by 180 ° from FIG. 10 shows the moment when the front ends of both rotating parts 1a and 1b enter the crossing part on the opposite side to FIG. In this state, of the eight ports P1 to P8, four of the ports P1, P3, P5, and P8 are “open”, and the remaining four of the ports P2, P4, P6, and P7 are “closed”. . Before and after this, since the crossing portions of the rotation paths 5a and 5b are not blocked, expansion and contraction due to confinement of the space does not occur. For this reason, the supply / discharge valves of the ports P1 to P8 are closed.

In the state of FIG. 16 in which the phase is advanced by 210 ° from FIG. 10, the port is in the same state as in FIG. 15, but from this position, the intersection of the rotation paths 5a and 5b is completely blocked by both rotation portions 1a and 1b. . For this reason, the regions Sb4 and Sb4 are confined from this position and expansion is started, and the supply and discharge valves of the ports P4 and P6 that open to these parts are opened. Thereby, the fluid flows into the regions Sa4 and Sb4 through the ports P4 and P6.

In the state of FIG. 17 in which the phase is advanced by 270 ° from FIG. 10, the ports P1 and P8 are newly opened → closed. For this reason, the regions Sa3 and Sb3 are confined and reduced, and the supply / discharge valves of the ports P3 and P5 that open to these regions are opened. As a result, the fluid in the areas Sa3 and Sb3 flows out through the ports P3 and P5.

In the state of FIG. 18 in which the phase is advanced by 330 ° from FIG. 10, the rear of the rotating portions 1a and 1b starts to exit from the intersection of the rotating paths 5a and 5b. Prior to this, the ports P2 and P7 are substantially closed and opened shortly before, and the expansion of the regions Sa4 and Sb4 in the binding state is completed. For this reason, the ports P2, P4, P6, and P7 that open to these portions are closed.

In the state of FIG. 19 in which the phase of 345 ° has advanced from FIG. 10, both rotating parts 1a and 1b begin to withdraw from the intersections of the rotation paths 5a and 5b, and the blocking of the intersections is released. Close the P8 supply / discharge valve.

That is, in this rotating machine, when the center of the rotating direction of one rotating part 1a (1b) is at the center of the intersection of the cover part 2 as shown in FIG. 17, the moving of the other rotating part 1b (1a) The center of the direction is also located at the center of the crossing portion on the opposite side of the cover portion 2, and when the two rotating portions 1a and 2a start to rotate simultaneously at the same speed, the ports P4 and P6 are inflow ports in the state of FIG. Ports P3 and P5 are outflow ports. In the state shown in FIG. 13, ports P1 and P8 are inflow ports and ports P2 and P7 are outflow ports. In this way, while the eight ports of the rotation paths 5a and 5b divided at the two intersections are interchanged, the flow of fluid basically flows through the four ports although there is a slight shift in the opening / closing timing of the supply / discharge valve. The outflow will occur at the same time.

Therefore, this rotary machine can function as a pump that discharges the fluid sucked in from the inflow port from the outflow port by receiving rotational power from the outside via the interlocking mechanism. By supplying and draining the outflow port, the rotational power can be taken out from the interlocking mechanism and function as a motor or an actuator. Of course, the operation can be performed in the same manner as described above only by reversing the relationship of the inflow / outflow ports with respect to the rotation in the reverse direction.

Incidentally, a simple interlocking mechanism 6 is illustrated in FIG. This interlocking mechanism 6 forms rack teeth 6a and 6b around the inner periphery of the support part 4 that supports the inner peripheral side of the rotating part 1a and the side surface of the support part 3 that supports the outer peripheral side of the rotating part 1b. A shaft 62 provided with pinion teeth 61 is provided at a position where the rack teeth 6a and 6b mesh with each other, and by rotation of the shaft 62, the two support portions 3 and 4 are interposed via the rack teeth 6a and 6b. Are synchronously rotated around an orthogonal axis passing through the virtual axis O. Then, by appropriately setting the number of teeth of the pinion teeth 61 and the rack teeth 6a and 6b, the rotational speeds of both the support portions 3 and 4 and thus both the rotation portions 1a and 1b can be matched. Of course, other interlocking mechanisms can be used. Further, the opening / closing timing of the supply / discharge valve can be easily synchronized by an ordinary electrical and mechanical method using, for example, the rotation of the shaft 62, and an automatic opening / closing valve based on a pressure difference is also conceivable.

As an assembling procedure of this rotating machine, cover inner walls 21, 22 and cover side walls 23, 24, 25, 26, 27a, 27b, 28a, 28b of the cover part 2 shown in FIG. And the movable part which consists of the outer side support part 3 is cut into two with the great circle Z (equatorial part shown in FIG. 7), and is created. Then, the cover outer wall 22 and the cover side walls 27a, 27b, 28a, and 28b are placed on the movable part composed of the rotating part 1a and the inner support part 4, and each movable part divided by the great circle Z is interposed between the cover inner wall 21 and the movable part. The operation of covering the cover outer walls 23, 24, 25, and 26 from both sides of the abutment is performed without interfering with each other (that is, the movable part including the rotating part 1a and the inner support part 4 when the divided movable parts are abutted) And finally, the adjacent cover parts are connected to complete the assembly of the rotary machine of this embodiment. In this case, the above-described interlocking mechanism 6 attaches or engraves the rack teeth 6a and 6b to both the support portions 3 and 4 before attaching the cover, and attaches the shaft 62 having the pinion teeth 61 to the pinion teeth 61. The position of the rack teeth 6a and 6b is adjusted.

Of course, it is not limited to such a structure and procedure, and the corresponding cover inner wall and cover side wall (for example, 21 and 23, 24) or cover outer wall and cover side wall (for example, 22 and 27a, 27b) are integrated. You can make it. Further, for example, when the outer support portion 3 is cut from the position opposite to the rotating portion 1a as indicated by an arrow T in FIG. 7, the rotating portion 1a and the inner supporting portion that are the inner parts are not necessarily separated by the great circle Z. 4 can be inserted, and the cover inner wall 21 can be mounted even after the two movable parts are joined.

In addition, among the support portions 4 and 3 that support the fan-shaped rotation portions 1a and 1b from the inside and the outside, portions other than the spherical support surfaces 41 and 31 can be freely formed. By matching the center of gravity of the movable part consisting of the rotating part 1a and the support part 4 or the center of rotation O and the center of gravity of the movable part consisting of the rotating part 1b and the support part 3, vibration, noise and energy loss during rotation can be reduced. It can be effectively reduced. For that purpose, it is possible to take appropriate measures such as adjusting the thickness of the portions other than the support surfaces 41 and 31, or attaching a balance weight separately. And parts other than the support surfaces 41 and 31 are also appropriate as the constituent places of the interlocking mechanism 6 and the power transmission system including the same as described above.

Moreover, as the structure which both rotation parts 1a and 1b occupy the area | region of about 180 degrees, and maintains airtightness without leaving a clearance gap, as shown in FIGS. For example, the front and rear end faces 14 in the rotational direction are cut at a slanting angle with respect to the rotational direction in a plane from the surface of the sphere toward the center O, and the angle of the longer arc of the sector is set to 180 degrees. FIG. 23 substantially corresponds to the states of FIGS. 10 to 11, and FIG. 24 substantially corresponds to the states of FIGS.

In addition, a shape in which the inclined portion of the end face 14b in FIG. 22 is turned upside down and the two sectors are brought into contact with each other is conceivable, and it is possible to pursue higher airtightness.

More precisely, since it is necessary to consider the relative displacement between the end faces 14a and 14b in the direction perpendicular to the paper surface in FIG. 22, generally speaking, the front and rear end faces of the two rotating portions 1a and 1b are rotated. However, it can be said that it is composed of a surface that keeps hermeticity, and the surface is formed by a collection of lines from the spherical surface toward the center.

  When the end face 14 is formed obliquely, as shown in FIGS. 23 and 24, the ports P1 and P6 are preferably located in the immediate vicinity of the intersection of the two rotation paths 5a and 5b, and the fluid paths are connected obliquely. It is preferable. As the position of the cover portion where these ports P1 and P6 are provided, it is effective to select the cover side walls 24 and 26 instead of the cover outer wall 22 and the cover inner wall 21 as shown in FIG. The situation is the same at the crossover on the opposite side. Also, in FIGS. 10 to 19, since the ports P1 to P8 are preferably provided as close to the intersections of the two rotation paths 5a and 5b as much as possible, the same configuration as in FIG. 25 can be employed. .

  Furthermore, the aspect which uses the rotary machine of this invention as an engine is outlined.

In this rotating machine, by providing a connecting portion (see an imaginary line B in FIGS. 13 and 18) that connects two paths at an appropriate place of the cover unit 2, gas compressed in one of the rotating paths 1a and 1b is already generated. On the other hand, it explodes and expands to function as an engine.

That is, with respect to the engine, compression is performed in front of the rotation direction of the rotation unit 1b in one rotation path 5b, intake is performed in the rear, and explosion and expansion are performed in the rotation direction of the rotation unit 1a in the other rotation path 5a. , So that the exhaust is done in front. In the connection portion B, the mixed gas compressed in the rotation direction of the rotation unit 1b in one rotation path 5b is sent to the position before the explosion in the rotation direction of the rotation unit 1a in the other rotation path 5a. It is provided at the position. At that time, the spark plug may be provided at an appropriate position, and may be configured to be ignited by high pressure like a diesel engine.
