Abstract

A rotary machine efficiently operable with less noise and vibration. The rotary machine is so formed that two rotating parts (1a, 1b) having side faces (13) formed in roughly fan shapes and outer peripheral surfaces (11) and inner peripheral surfaces (12) formed in partially spherical surfaces with a same virtual center point (O) are rotated in synchronism with each other at such a timing that does not touch each other on rotating surfaces crossed at right angle to each other around the virtual center point (O). One rotating part (1a) comprises a support part (4) on the inner peripheral surface side, and the other rotating part (1b) comprises a support part (3) on the outer peripheral surface side. A cover part (2) is installed at a position for covering the support parts (4, 3) and rotating routes (5a, 5b). The rotating part (1a)[(1b)] is rotated in such a manner that it shields a rotating route (5b)[(5a)] for the mating rotating part (1b)[(1a)] at a crossing part. As a result, a space closed by the support part (4)[(3)], the cover part (2), the side face (13) of the rotating part (1a)[(1b)], and the end face (14) of the other rotating part (1b)[(1a)] can be varied according to the rotation of the both rotating parts (1a, 1b).

Rotating machine

Technical field

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

Background art

[0002] For a rotary machine that operates using external power, or a rotary machine that outputs power by injecting working fluid or fuel, for example, a pump z motor actuator using an eccentric operation or a reciprocating type Engines that extract rotational power from piston motion are widely known. These rotating machines are well known without needing to be specifically illustrated.

Disclosure of the invention

Problems to be solved by the invention

[0003] However, these conventional pumps, engines, actuators, etc. have a loss of energy due to the reciprocal movement of the piston due to the discrepancy between the center of rotation and the center of gravity of the rotating part due to the eccentricity of the cylinder block. There was a problem of large vibration and noise.

[0004] Also, there is a force that is eccentric and clogged, such as a pump with a structure. This type rotates in the housing without force that the mouth makes line contact with the inner wall of the housing! Because it is a common practice, it has become large and high-speed to compensate for the poor airtightness, making it unsuitable for high-pressure pumps and engines.

[0005] The present invention has been made paying attention to these problems, and eliminates the drawbacks of conventional rotating machines, enabling high efficiency, low vibration, low noise, and high-speed rotation like an electric motor. The purpose is to realize a rotating machine with a structure that can be used effectively as a pump, engine, actuator, etc.

Means for solving the problem

[0006] In order to achieve the above object, the present invention takes the following measures.

[0007] That is, the rotating machine of the present invention has two rotating parts and a shape of a part of the rotating parts. The rotating parts have a phantom center point of the spherical surface of the shape as the same center. straight When it hits on the rotating surface that makes a corner, it is made to rotate at the same timing. In this case, 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 with the rotation of the rotating part.

With this configuration, one rotating part closes the front and rear of the rotating path of the other rotating part at the intersection of the rotating paths 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 the rotation, and the closed area behind the rotation part becomes wider with the rotation. Therefore, if a hole is drilled near the intersection of some rotation paths, it will function as a pump or actuator.

[0009] 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. Since it can be brought into surface contact or close to a state over a wide range, the airtightness is remarkably improved, and it is possible to make a rotating machine that operates with high efficiency even if it is small * low rotation.

[0010] Specifically, the two rotating part forces 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. It is configured to synchronize and rotate at the same timing so as not to interfere with the rotating surface. At that time, 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 rotating path together with the supporting part. Thus, the rotating parts rotate in such a way as to gradually block the rotation path of the other rotating part at the intersection, so that the supporting part, the cover part, the side surface of the rotating part, and the other This is characterized in that the space closed by the end face of the rotating part of the rotating part expands and contracts with the rotation of both rotating parts.

[0011] In this case, in order to prevent vibration and noise, one support portion has a shape in which a spherical surface having the same virtual center as the inner peripheral surface of the rotating portion is expanded in the arc direction of the position force fan in contact with the inner peripheral surface. The other support part is a position where a spherical surface having the same virtual center as the outer peripheral surface of the rotating part is in contact with the outer peripheral surface. It is useful to have a shape that extends in the direction of the arc of the fan, balance the mass at these extended portions, and make the virtual center point coincide with the center of gravity of the movable portion consisting of the rotating portion and the supporting portion.

[0012] In order to associate this rotating machine with the power transmission system, the two support portions are connected by a linkage mechanism such as a gear, and the timing of rotation of both rotation portions is matched by this linkage mechanism, and via the linkage mechanism. Thus, it is preferable that the rotation force is input to the rotation unit and the rotation force is output from the rotation unit.

[0013] In order for this rotating machine to function as a pump, a motor, or an actuator, a hole that opens in a closed space is provided in the cover portion, and the space is expanded or contracted due to rotation of the rotating portion. It is only necessary to connect the fluid path to each hole and configure the power transmission system so that the hole that opens is a suction port or a high-pressure port, and the hole that opens to the reduced region becomes a discharge port or drain port. Various fluids such as water, air, and oil can be used as the fluid.

[0014] 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 portion, and two rotation paths other than the crossing portion are utilized using a part of the hole. By providing a connection part connected at this point, the gas mixture confined in one rotation path and introduced into the space in the contracting process is compressed, and the gas mixture is closed in the other rotation path via the connection part. If it is introduced into a space that is in the process of expansion and then explodes, expands and then exhausts continuously, it can be configured to operate continuously.

[0015] 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 even at high speeds. A durable rotating machine and a pump Z motor, actuator, and engine using this 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 compared to the conventional non-eccentric type.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0018] In the rotating machine of this embodiment, two rotating parts l (la, lb) indicated by solid lines in FIG. 1 are provided on rotating paths 5a, 5b provided on rotating surfaces orthogonal to each other indicated by imaginary lines in FIG. It is designed to rotate synchronously without interfering along. The rotation paths 5a and 5b are partially covered by the force bar portion 2 shown in FIGS. 2 and 6, and the rotation portions la and lb rotate while being backed up by the support portions 4 and 3 shown in FIGS. It is arranged in the paths 5a and 5b. In this state, the movable part composed of the rotating part la and the support part 4 rotates with the rotation path 5a closed, and the movable part composed of the rotation part lb and the support part 3 rotates with the rotation path 5b closed. To make a structure. Fig. 7 is an exploded view showing the assembly relationship between the rotating part and the cover part.

Specifically, the outer periphery 11 and the inner periphery 12 of the rotating part l (la, lb) are spherical surfaces having the same virtual center point O, and the side surface 13 extends from the outer periphery 11 to the inner periphery 12 as the spherical surface. It is formed by a curved surface created by a collection of lines facing the center of the sphere, that is, the same virtual center point O. This curved surface is a conical surface. In the present specification, the side surface shape of the rotating portion 1 is referred to as a “fan shape”, but it is formed by an outer periphery 11 and an inner periphery 12 and an end surface 14 to be described later, as clearly shown in FIG. It is a partial annular shape in a side view. Other terms “fan” and “fan” have the same meaning.

[0020] The rotating portion 1 is sized to fit within a region slightly smaller than 180 ° in the rotation paths 5a and 5b, that is, in a region where no force is applied to the intersection of the rotation paths 5a and 5b (the angle of the fan is The shape of the front and rear end faces 14 in the rotational direction is not particularly limited. Even in this way, the basic function is the same as the airtightness only 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 la and lb are supported by the supporting parts 4 and 3. 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 Positional force that backs up the outer circular arc or inner circular arc of the rotating part 1 that forms a fan shape. Of the support parts 3 and 4, the shape of the other parts except for the support surfaces 31 and 41 is arbitrary, and the vertical length of the arc of the fan-shaped part of the rotating part 1 and the paper surface in FIGS. The width in the direction and 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 portion 2 has a cover outer wall 22 that closes the outer peripheral side of the vertical rotation path 5 a in the figure, and an inner periphery of the horizontal rotation path 5 b in the figure. The cover inner wall 21 that closes the side also has a spherical force with the same virtual center point O, and the cover side walls 23, 24, 25, 26 covering the top and bottom of the rotation path 5b and the cover side walls 27a, 27b covering the left and right of the rotation path 5a, 28a and 28b are close to a semicircle formed by a curved surface formed by a collection of lines facing the same virtual center point O. These curved surfaces are also conical surfaces corresponding to the shape of the side surface 13 of the rotating part lb, la.

[0023] In the longitudinal rotation path 5a of the cover portion 2 shown in Figs. 2, 6, and 7, the rotation portion 1 (la) of Figs. 1, 4, 5, and 7 is also shown, and Figs. 7 and 7, the rotating part 1 (lb) shown in FIGS. 1, 3, 5 and 7 is accommodated in the horizontal rotating path 5b of the cover part 2, respectively. The rotating part 1 (la) constitutes a movable part together with the support part 4, and the rotating part 1 (lb) 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.

[0024] As described above, the side surface of the rotating part 1 (la, lb) is placed on the part other than the crossing part of the rotating paths 5a, 5b. J wall 23, 24, 25, 26, 27a, 27b , 28a, and 28b, and the outer peripheral surface 11 of the rotating part la arranged in the longitudinal rotation path 5a is partially spherical at the portion excluding the intersection of the rotation paths 5a and 5b. The cover outer wall 22 covers two places at the top and bottom, and the inner peripheral surface 12 of the rotating part lb arranged in the horizontal rotation path 5b is a partially spherical inner cover wall at the part excluding the intersection of the rotation paths 5a and 5b. 21 covers the left and right.

[0025] Then, the inner peripheral side of the rotation path 5a is closed by an annular support part 4 that supports the inside of the rotation part la including the intersections of both rotation paths 5a and 5b, and the outer periphery side of the rotation path 5b rotates in both directions. The structure is closed by an annular support portion 3 that supports the outside of the rotating portion lb including the crossing portions of the paths 5a and 5b.

[0026] At this time, the shape of the portion of the cover portion 2 that comes into contact with the movable portion consisting of the rotating portion la and the support portion 4 and the shape of the portion that comes into contact with the movable portion consisting of the rotating portion lb and the support portion 3 are When the movable part is rotated, it always slides in close contact with each part of the cover part 2 and airtightness is maintained. I am doing so.

[0027] Then, holes are provided at appropriate locations in the cover portion 2 and these are used as input / output ports so as to function as a pump and an actuator.

[0028] As shown in Fig. 6, the holes in the present embodiment have two locations (Pl, P2, P3, P4) on the cover outer wall 22 of the longitudinal rotation path 5a in the vicinity of each crossing portion, and in the vicinity of each crossing portion. Are provided in two places (P5, P6, P7, P8) on the inner wall of the cover of the horizontal rotation path 5b, for a total of eight places.

[0029] Next, the operation of the rotating machine will be briefly described. For example, the system is in the rotation state shown in FIG. 8, and at each intersection of the rotation paths 5a and 5b, the rotation part la (lb) passes the front and rear of the rotation path 5b (5a) of the other rotation part lb (la). When closed, the closed region Sbl (Sal) between the front of the rotating part lb (la) and the side of the rotating part la (1 b) becomes narrower with the rotation, and the rear of the rotating part lb (la) The closed region Sb2 (Sa2) between the sides of the rotating part la (lb) becomes wider with rotation. Therefore, in this figure, Pl 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 at each intersection of the rotation paths 5a and 5b, the rotation part la (lb) is replaced with the other rotation part lb (la ), The closed area Sb3 (Sa3) between the front of the rotating part lb (la) and the side of the rotating part la (lb) rotates. The closed region Sb4 (Sa4) between the rear of the rotating part lb (la) and the side surface of the rotating part la (lb) becomes wider with rotation. Therefore, in this figure, P4 and P6 are inflow ports, and P3 and P5 are outflow ports.

[0030] FIGS. 10 to 19 further show the rotation paths 5a and 5b developed and graduated every 30 °. The right shoulder of each figure shows the rotating parts la, lb from the state of FIG. It shows how much force is rotated and its phase difference. The state of FIG. 13 substantially corresponds to FIG. 8, and the state of FIG. 17 substantially corresponds to FIG. A flow path (not shown) is connected to each of the ports P1 to P8, and an appropriate supply / discharge valve is provided in each flow path.

[0031] The state of FIG. 10 shows the moment when the front ends of both rotating parts la and lb enter the crossing part. In this state, of the eight ports P1 to P8, all four ports Pl, P3, P5, and P8 are “low”, and the other four ports P2, P4, P6, and P7 are “open”. Become. Before and after this, the intersections of the rotation paths 5a and 5b are not blocked, so there is no expansion or contraction in the confinement state of the space. . However, the supply / discharge valves of ports P1 to P8 must be closed.

[0032] In the state of Fig. 11 where the phase is advanced by 15 ° from Fig. 10, ports Pl and P8 are switched from closed to open, ports P3 and P5 are still "closed", and ports P2, P4, P6 and P7 are still " Open. Even before and after this, the intersections 5a and 5b of the rotation path are not blocked, and expansion and contraction in the confined state of the space does not occur. During this time, it is necessary to close the supply and discharge valves of ports P1 to P8, as in the state of Fig. 10.

[0033] In Fig. 12, which is 30 ° out of phase from Fig. 10, the states of ports P1 to P8 are the same as in Fig. 11. Force At this stage, the intersection of rotation paths 5a and 5b is completely completed by both rotation parts la and lb. Will be blocked. For this reason, the position force regions Sa2 and Sb2 are confined and expansion is started, and the supply and discharge valves of the ports Pl and P8 that open to these portions are opened. As a result, fluid flows into the regions Sa2 and Sb2 via the ports Pl and P8.

[0034] In the state of Fig. 13 in which the phase is advanced by 60 ° from Fig. 10, port P4, P6 force ^ closed ". For this reason, the areas Sal and Sbl are confined from a position slightly ahead, and the contraction starts, and the ports P2 and P7 that open to this area are opened. As a result, the fluid in the areas Sal and Sbl flows out through the ports P2 and P7.

[0035] The state of Fig. 14 where the phase has advanced 150 ° from Fig. 10 is the moment when the rear of both rotating parts la and lb begins to exit from the intersection of both rotating paths la and lb, and ports P3 and P5 are closed. → The area is opened and the expansion in the closed state of areas Sa2 and Sb2 ends. For this reason, the ports Pl, P3, P5, and P8 that open to these parts 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 la and lb enter the crossing part on the opposite side to FIG. In this state, of the eight ports P1 to P8, the four ports Pl, P3, P5, and P8 are “open”, and the remaining four ports P2, P4, P6, and P7 are “closed”. . Before and after this, the intersections of the rotation paths 5a and 5b are not blocked, so that expansion and contraction due to confinement of the space does not occur. For this reason, close the supply and discharge valves of ports P1 to P8.

[0037] In the state of Fig. 16 where the phase is advanced 210 ° from Fig. 10, the port is the same force as in Fig. 15. From this position, the intersection of rotation paths 5a and 5b is completely blocked by both rotation portions la and lb It is done. For this reason, this positional force is also confined to the regions Sb4 and Sb4, and expansion begins. Open ports P4 and P6 that open to the part of. As a result, fluid flows into the regions Sa4 and Sb4 via the ports P4 and P6.

[0038] In the state of Fig. 17 in which the 270 ° phase has advanced from Fig. 10, the ports Pl and P8 are newly opened and closed. For this reason, the regions Sa3 and Sb3 are confined and reduced, and the supply and discharge valves of the ports P3 and P5 that open to these regions are opened. As a result, the fluid in the regions Sa3 and Sb3 flows out through the ports P3 and P5.

[0039] In the state of Fig. 18 in which the phase has advanced by 330 ° from Fig. 10, the rear of the rotating portions la and lb 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 parts are closed.

[0040] In the state of Fig. 19 where the phase is advanced from Fig. 10 by 345 °, both rotating parts la and lb begin to exit from the crossing part of the rotation paths 5a and 5b, and the crossing part is released. Close the supply / discharge valves of ports P1 to P8.

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

[0042] 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 a high-pressure fluid to the drain and using the drain port as a drain, it is possible to extract rotational power from the interlock mechanism and to 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 reverse rotation. [0043] 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 rotary part la and the side surface of the support part 3 that supports the outer peripheral side of the rotary part lb, respectively. A shaft 62 having a pinion tooth 61 is provided at a position mating with the rack teeth 6a, 6b, and two support portions are provided via the rack teeth 6a, 6b by the rotation of the shaft 62. 3 and 4 rotate synchronously around the orthogonal axis passing through the virtual axis O. Then, by appropriately setting the number of teeth of the pion teeth 61 and the rack teeth 6a and 6b, the rotational speeds of the support portions 3 and 4 and consequently the rotating portions la and lb can be matched. Of course, other interlocking mechanisms can be used. In addition, the opening / closing timing of the supply / discharge valve can be easily synchronized with the usual electrical and mechanical methods using, for example, the rotation of the shaft 62, and an automatic opening / closing valve based on a pressure difference is also conceivable. .

[0044] As an assembling procedure of this rotating machine, cover inner walls 21, 22 and Kanoichi J walls 23, 24, 25, 26, 27a, 27b, 28a, 28b of cover 2 shown in FIG. The movable part consisting of the rotating rod lb and the outer support part 3 is created by cutting it into two with a great circle Z (equatorial part shown in Fig. 7). Then, the cover outer wall 22 and the cover side walls 27a, 27b, 28a, and 28b are covered with the movable portion composed of the rotating portion la and the inner support portion 4, and each movable portion divided by the great circle Z is interposed between the cover inner wall 21 and the cover inner wall 21. The both sides of the butt are placed on the cover outer wall 23, 24, 25, 26 without interfering with each other (i.e., the movable part consisting of the rotating part la and the inner support part 4 when the divided movable parts are brought together). The assembly of the rotating machine according to the present embodiment is completed by connecting a part of the adjacent cover at the end. In this case, the above-described interlocking mechanism 6 attaches or engraves the rack teeth 6a and 6b to the two support portions 3 and 4 before attaching the cover, and attaches the shaft 62 having the pinion teeth 61 to them. -Adjust the position of the ON teeth 61 and the rack teeth 6a, 6b.

[0045] Of course, the corresponding cover inner wall and cover side wall (for example, 21 and 23, 24) or the cover outer wall and cover side wall (for example, 22 and 27a, 27b) are not limited to such structures and procedures. May be made in one piece. Further, for example, when the outer support portion 3 is cut from the position opposite to the rotating portion la as indicated by an arrow T in FIG. 7, the rotating portion la and the inner portion are not necessarily separated by the great circle Z. A movable part composed of the inner support part 4 can be inserted, and the inner wall 21 of the force bar can be mounted even after the two movable parts are joined. [0046] In addition, among the support portions 4 and 3 that support the fan-shaped rotating portions la and lb on the inner and outer forces, portions other than the spherical supporting surfaces 41 and 31 can be freely formed. By matching the center of gravity of the movable part consisting of the center O and the rotating part la and the support part 4 or the center of rotation of the movable part consisting of the center O and the rotating part lb and the supporting part 3, vibration, noise during rotation, The loss of energy can be effectively reduced. For that purpose, it is possible to take appropriate measures such as adjusting the thickness of portions other than the support surfaces 41 and 31, or attaching a balance weight separately. The parts other than the support surfaces 41 and 31 are also suitable as the construction place of the interlocking mechanism 6 and the power transmission system including the same as described above.

[0047] In addition, as a structure in which both rotating parts la and lb occupy an area of approximately 180 ° and rotates without air gaps while maintaining airtightness, for example, as shown in FIGS. The front and rear end faces 14 in the direction of rotation of lb should be cut at a slant angle with respect to the direction of rotation at the plane from the surface of the sphere toward the center O, so that the angle of the longer arc of the sector is 180 degrees. Can be mentioned. FIG. 23 substantially corresponds to the state of FIG. 10 to L 1 above, and FIG. 24 substantially corresponds to the states of FIG. 15 to FIG.

[0048] In addition, a shape in which the inclined portion of the end face 14b in Fig. 22 is turned upside down and the two fan-shaped surfaces are in contact with each other is conceivable, and it is possible to pursue higher airtightness.

[0049] 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 of the two rotating parts la and lb. It can be said that the end face is formed of a surface that keeps hermeticity while rotating, and that the surface is formed by a collection of force lines centered on the spherical surface.

[0050] When the end face 14 is configured obliquely, as shown in FIGS. 23 and 24, it is desirable that the ports Pl and P6 be positioned in the immediate vicinity of the intersection of both the rotation paths 5a and 5b. It is preferable to connect at an angle. As the position of the cover portion where these ports Pl 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.
