Definitions
- the invention relates to the field of engineering, namely to rotary volumetric machines that can be used as pumps, hydraulic motors, including adjustable hydraulic drives of vehicles.
- ORM (US 2708413 E. Loewen FIG. 18), comprising a housing with a sphere-shaped working cavity, a rotor with a working surface of rotation mounted in the housing rotatably, a spacer made in the form of a flat ring mounted in the housing with the possibility of rotation about an axis, perpendicular to the axis of the rotor and dividing the working cavity into two parts, and on the working surface of the rotor two grooves are made along its geometric axis of rotation, in which it is installed with the possibility of overlapping the working cavity and rotate nyh oscillations around its geometric axis intersecting the geometric axis of the rotor on the one piston in the form of at least half of a flat ring.
- the separator uses a sealing element in the form of a flat ring with sections of cylindrical surfaces on one side of the ring, the axis of which lies in the plane of the ring.
- the reciprocal cylindrical platforms made on the pistons interact with them. Due to the sphere-like nature of the working cavity and the use of sealing elements, the contact surfaces between the working bodies pass along the platforms (and not along the lines), which reduces the internal flows of the working fluid.
- ORM is not widespread. The reason is the unreliable engagement of the rotating sealing element with the piston, since all the normals of the employees for their engagement of the cylindrical platforms (especially the areas on the pistons) are directed mainly across the separator. As a result, the friction forces inhibiting the sealing element and acting along the separator, directed at an acute angle to the supporting surfaces, which creates conditions for jamming. It is not possible to increase the angular length of the cylindrical platforms on the piston and on both sealing elements so that there are normals oriented mainly along the separator because of the location of the separator between them and the need to provide the possibility of changing the angle between the piston and the separator during rotation of the rotor.
- the disadvantage is the presence of two pairs of windows of the entrance and exit of the working fluid on the housing of each stage, as well as their small angular dimensions.
- the latter is due to the fact that in order to maintain pressure by one stage of the ORM, the length of the windows should not exceed the thickness of the piston.
- the disadvantage is that for mounting the SSE, its axis must be in the outer part of the separator, which leads to an increase in the thickness of its outer part and, as a result, the moment of inertia. Since there is unevenness in the rotation of the separator, an increase in its moment of inertia limits its maximum linear speed at which the ORM can operate.
- the main SSE support working against the friction forces between the separator and the housing is located inside the outer part of the separator, while the point of load application by the frictional forces is in the separator slot, therefore the shoulder of the SSE supports is less than the load forces. As a result, the load of the friction pair axis SSE - separator increases decreasing resource.
- the disadvantage is the presence of two pairs of windows of the input and output of the working fluid on the housing of each stage. Moreover, to connect the input / output windows to each other, it is necessary to bypass the groove of large diameter available in the cavity of the housing for installing the separator. This increases the mass and complexity of the housing, reduces the specific characteristics of the ORM. Especially if you use two steps and have to connect eight windows.
- the disadvantage is the presence of a flat portion of the rotor passing through the slot in the sealing synchronizing element. It does not allow the channels for the working fluid to pass through the rotor, it limits the maximum working pressure and maximum torque that can be transmitted to the next hydraulically parallel stage of the ORM, which is required for obtaining an almost uniform feed.
- Known ORM (patent RU 2376478), comprising a housing, the working surface of which is made as part of a segment of a sphere, a rotor with a working surface of rotation mounted rotatably in the housing, an annular concentric working cavity formed by the housing and the rotor, a separator made in the form of an inclined washers mounted motionlessly in the housing at an angle to the geometric axis of rotation of the rotor and dividing the working cavity into two parts, and at least one groove along its geome is made on the working surface of the rotor ternary axis of rotation, a piston is installed in the rotor with the possibility of overlapping (sealing) the working cavity and performing rotational vibrations around its geometric axis intersecting the geometric axis of the rotor, and the piston is made in the form of at least part of the disk, and each piston has at least at least one sealable slot for the passage of the separator.
- the main support of the SSE to counter the forces created by the pressure drop in the stage and the friction forces between the SSE and the separator directed across the piston, is located inside a piston located inside the rotor, while the point of application of these forces is outside the rotor, therefore the shoulder forces of the SSE support are less than those of the load forces.
- the maximum pressure maintained by one stage and the resource are limited by the wear resistance of the friction pair axis SSE - piston.
- the disadvantage is the significant predominance of the area of loaded surfaces in SSE compared with unloaded.
- This ORM is the closest analogue.
- the objective of the invention is to provide a reliable, capable of withstanding short-term pressure overload, thermal overload, compact ORM with a large specific power and resource. This implies the need to exclude highly loaded friction pairs from the ORM design.
- the volumetric rotary machine comprises a housing, a rotor, at least one piston, at least one separator, a sphere-shaped working cavity formed around the rotor, the entrance and exit windows of the working fluid, and at least a part the piston is mounted with the possibility of performing rotational vibrations relative to the rotor in a plane extending mainly along the axis of the rotor and at least a part of the separator is mounted for rotation around the rotor, and the piston or its part is connected articulated with a separator or part thereof.
- the articulation of the piston with the rotary separator can be made reliable, and all parts have enough open surfaces to remove heat from friction pairs.
- the most loaded friction pairs in analogues - SSE axes are absent in this design. Additionally, reliability is increased by eliminating small parts - SSE.
- the objective of the invention is also achieved in that the hinged connectors on the piston and on the separator are made in the form of a combination of a cylindrical thickening and a slot with coaxial thickening concave cylindrical platforms.
- the objective of the invention is also achieved in that the hinge connector on the piston is made in the form of an arcuate bend, and on the separator in the form of an arcuate slot.
- hinge connector on the piston is made in the form of an arcuate slot, and on the separator in the form of an arcuate bend.
- the objective of the invention is also achieved by the fact that inside the rotor there are channels for the working fluid leading to the other side of the separator, in order to be able to supply the working fluid to the working chambers and / or to remove the working fluid from the working chambers from only one side of the separator.
- the objective of the invention is also achieved in that the separator is mounted with the possibility of changing the angle of its inclination to the axis of rotation of the rotor in order to regulate the flow of the machine.
- the objective of the invention is also achieved by the fact that on the rotor there is a spherical part located concentrically in a sphere-shaped cavity, and the entrance window and the exit window are made on the spherical part on opposite sides of the piston.
- the objective of the invention is also achieved in that the separator, in addition to the part rotating around the rotor, has a static part, which reduces the load on the rotating part.
- the objective of the invention is also achieved in that there is an additional piston and for interacting with it, the separator consists of parts moving relative to each other.

- the separator may consist of moving relative to each other parts.
- the volumetric rotary machine (ORM) of FIG. 1 can be used as a pump and / or hydraulic motor. It consists of two steps 1 and 2. Steps 1 and 2 have a common housing 3 and a common rotor 4 mounted in the housing 3 with the possibility of rotation.
- the geometric axis 5 of rotation of the rotor 4 is the axis of the ORM.
- the piston 6 is installed with the possibility of performing rotational vibrations relative to the rotor 4 in a plane extending mainly along the axis 5 of the rotor 4, and a separator 7 is mounted with the possibility of rotation around the rotor 4.
- a separator 7 is mounted with the possibility of rotation around the rotor 4.
- the ORM case 3 is made of two practically (up to the fastener elements and grooves for seals), mirror-symmetric parts 8 and 9 (Fig. 3, 4).
- the plane of the connector 10 between them passes through the axis of rotation 5 of the rotor 4.
- In the housing 3 there are two sphere-shaped cavities 11 (one per step), the centers of which lie on the axis 5.
- a cylindrical hole under the rotor 4 passes through the cavity 11 divide it into three sections: the middle 12, located between the cavities 11, and two extreme 13 and 14, extending beyond the cavity 11 in opposite directions.
- each sphere-shaped cavity 11 there is a symmetrically located in it, open in it circular groove 15 of a larger external diameter than the diameter of the cavity 11. That is, it is made on the surface of the cavity 11.
- the groove 15 is bounded by a lateral sphere-shaped surface 16 (FIGS. 2, 3), the center of which coincides with the center of the cavity 11 and two ends 17 in the form of symmetrically arranged parallel flat rings.
- the axis of symmetry 18 (the axis of rotation of the generatrix of the groove 15) is located in this example at an angle of 25 degrees to the axis 5 and lies in the plane of the connector 10.
- the entry window 20 has a rectangular shape with rounded corners. It has an angular length of more than 1 A revolution around axis 5 (in this example, 106 degrees).
- the input window 20 goes into a cylindrical pipe 21 of the input of the working fluid, at the end of which there is a thread 22 (figure 4) for connecting the supply lines.
- Sections 13 and 14 of the cylindrical bore serve as sliding bearings for the rotor 4.
- discharge grooves 26 (Fig. 2) in the form of rectangular (in cylindrical coordinates) closed loops with rounded corners. According to the angular extent around axis 5 along the outer the boundary they are equal to the angular extent of the entrance window 20. In size along the axis 5, each contour is approximately equal to half the same size of the input window 20.
- the grooves 26 of both circuits are connected by tubes of small diameter (not shown) running along the outer surface of the housing 3, with an exit window 23 on the second part 9 of the housing 3 (FIG. 3).
- a coaxial axis 5 of the outlet 29 of a smaller diameter At the end 27, from the cylindrical section 13 there is a coaxial axis 5 of the outlet 29 of a smaller diameter. It has an annular groove 30 for diverting leaks from the high-pressure region to the low (inlet) pressure zone, connected by small-diameter tubes (not shown), through check valves, with an inlet window 20 and an outlet window 23. Further from the cavity 11 in the hole 29 there is an annular groove 31 for installing seals (the seals themselves are not shown). Further from the cavity 11 in the hole 29 there is an annular groove 32 for collecting leaks from the low pressure region (from the groove 30) that have passed through the seals. It is needed when operating ORM in a closed circuit with a high inlet pressure.
- the outer surface of the housing 3 (figure 4) with an offset approximately follows the shape of its inner cavity.
- a protrusion 35 is formed around the groove 15.
- the manufacture of parts of the casing 3 for high pressure ORM is assumed to be by casting, followed by refinement by electrical discharge method.
- Steps 1 and 2 of the rotor 4 are made on one cylindrical shaft. They divide it into three sections: middle 36, and two extreme 37 and 38, extending to the outside from steps 1 and 2.
- Each step of the rotor 4 has a central spherical part 39 with a center on axis 5 and a diameter close to the diameter of the shaft. From the opposite along the axis 5 of the sides of it there are two side walls 40 made in the form of truncated cones, coaxial to the axis 5, symmetrically supported by smaller bases on the spherical part 39.
- the side walls 40 are connected to sections 36 and 37 on stage 1 and sections 36 and 38 on stage 2 transitional sections 41 having spherical surfaces, the diameter of which is larger than the diameter of the shaft, and the centers coincide with the centers of the corresponding central spherical parts 39. Between the two side walls 40 of each stage, an annular cavity 42 open outward is obtained, the bottom of which is the surface of the spherical part 39.
- a groove 43 passes under the piston 6.
- the groove 43 extends to a shallow depth into the spherical part 39 in the form of an annular groove whose geometric center coincides with the center of the spherical part 39.
- the grooves 43 touch the sections 36, 37, 38.
- the groove 43 looks like a symmetrical through rectangular groove through the rotor 4, minus the cylinder 47 left in the spherical part 39.
- the end surfaces 44 of the groove 43 are flat e and parallel to the axis 5.
- the grooves 43 divide the channel 42 into two identical parts 46.
- the stage 2 is rotated relative to the stage 1 by ⁇ of a revolution about the axis 5.
- Two windows 51 are symmetrically relative to axis 5, and two windows 52 are symmetrically rotated by% of turn.
- Channels 49 have a cross section in the form of a smaller part of a circle cut off by a chord with rounded corners. Based on the function of the channels 49, it would be more correct to say that each channel 49 transfers the working fluid from one side of the spherical part 39 to the opposite of it (or its center) side, and then it goes into the channel 50, leading to the windows of the entrance 20 / exit 23 of the working fluid.
- another channel 48 is connected to them along the way (in the region of the stps or in another place) from the side opposite to the center of the spherical part 39 (also from the opposite side of the groove 43).
- the outputs of the channels 48 have a sufficiently large angular extent (in this example, more than 90 degrees), and therefore stiffeners 53 are left in them (Fig. 5).
- Four grooves 54 are made on the surface of sections 37 and 38 in the form of rectangular (in cylindrical coordinates) with rounded corners of closed contours having an angular length around axis 5 equal to the angular length of windows 51 or 52 and length along axis 5 equal to about half of the corresponding length windows 51 or 52.- Their position along the axis 5 coincides with the position of the grooves 26 on the housing 3, and the angular position coincides with the position of the windows 51 and 52. They serve as simulators of the windows 51 and 52 and together with the grooves 26 perform hydraulic rotor unloading 4.
- the ends 55 and 56 of the sections 37 and 38 respectively serve as thrust bearings to limit the movements of the rotor 4 in the axial direction.
- the manufacture of the rotor 4 is supposed to be by casting, followed by refinement by an electroerosive method.
- holes can be made that are coaxial to the axis 5, which extend in depth to the screw-shaped channels 49. Then, separately manufactured output shafts 58 are pressed into these holes.
- the separator 7 (Fig.7) has the shape of a body of revolution - a symmetrical ring. Conventionally, it is possible to distinguish on it the internal (that is, closest to its center, axis) part 60, and the external (that is, more distant from its center) part 61. In the figures, they are separated by a dashed-dotted circle.

- the axis 62 is the axis of rotation of the generatrix of the ring.
- the Central hole 63 in the ring is limited by a sphere-shaped surface having a diameter close to the diameter of the spherical part 39 of the rotor 4, so that the separator 7 is worn on it with a minimum clearance allowing their relative rotation.
- Outer side ring side 64 is bounded by a sphere-shaped surface concentric with the central hole 63, the diameter of which is close to the diameter of the sphere-shaped surface 16 of the housing 3.
- the ends 66 of the separator 7 are flat.
- the outer part 61 is used to interact with the groove 15 of the housing 3, and on the inner part 60 two coaxial hinge connectors 65 are symmetrically made.
- the connector 65 is made in the form of a blind hole going through the surface of the hole 63 from the center of the spacer 7, the axis of which 67 lies in the plane of the spacer 7.
- the diameter of the hole is greater than the thickness of the separator 7, therefore, the hole on the separator 7 forms a through slot 68 bounded by two cylindrical pads 69 resulting from the hole and the bottom of the hole.
- At the end of the hole there is a local cylindrical bulge 70 aligned with it of the same diameter. Under the cylindrical bulge 70 refers to two, protruding in different directions (ends 66) of the separator 7, coaxial convex cylindrical platform.
- the bottom of the hole is flat. It is the end face 71 of the thickening 70.
- the other end face 73 of the cylindrical bulge 70 is a concentric hole 63 with a sphere-shaped surface extending along the boundary of the inner part 60 and the outer part 61.
- the main meaning of the bulge 70 is that it creates cylindrical convex platforms that work as a friction pair with the piston 6.
- the separator 7 is central symmetrical.
- the piston 6 (Fig. 8) is made in the form of a flat ring.
- the ends 74 of the ring are flat, the outer side 75 is bounded by a sphere-shaped surface with a diameter close to the diameter of the cavity 11 for rotation in the latter without large gaps.

- On the outer part 78 two coaxial articulated connectors 79 are symmetrically made.
- the connector 79 is made in the form of a blind the hole going through the lateral side 75 towards the center of the piston 6, the axis 80 of which lies in the plane of the piston 6.
- the diameter of the hole is greater than the thickness of the piston 6, therefore, the hole on the piston 6 forms a through slot 81 bounded by two cylindrical pads 82 resulting from miles, and the bottom of the hole.
- Thickening 83 consists of two pistons 6 projecting in opposite directions (ends 74) of coaxial cylindrical platforms, the axis of which is directed toward the center of the piston 6.
- the flat bottom of the hole is the end face 84 of the thickening 83.
- the other end face 87 of the cylindrical bulge 83 is a concave spherical surface concentric to the lateral side 75 extending along the boundary of the inner part 77 and the outer part 78 of the piston 6.
- the main meaning of the bulge 83 is that it creates cylindrical convex platforms that work as a friction pair with a separator 7 Piston 6 is centrally symmetrical.
- the thickening 83 of the piston 6 enters the slot 68 of the separator 7 (Fig. 9), and the thickening 70 of the separator 7 enters the slot 81 of the piston 6.
- the axis 80 enters the hole 72.
- the cylindrical pads 82 of the slot 81 of the piston 6 work as a friction pair along the cylindrical thickening 70 of the separator 7, taking on mainly the loads acting in the plane of the piston 6 perpendicular to the axis 88 of the hinge 89.
- the cylindrical pads 69 of the slot 68 of the separator 7 work as a friction pair along the cylindrical thickening 83 of the piston 6, taking on mainly the load acting e in the plane of the separator 7 perpendicular to the axis 88 of the hinge 89.
- the loads acting along the axis 88 of the hinge 89 are perceived by the friction pair end 84 of the bulge 83 of the piston 6 - end 71 of the bulge 70 of the separator 7. All other loads are perceived by the friction pair piston 6 - rotor 4 and housing 3 - separator 7.
- the rotor 4 is made collapsible.
- the insert 90 is half of the cylinder 47 with its part from the protrusion 91.
- the section extends along a plane parallel to the ends 94 of the cylinder 47.
- the protrusion 91 extends beyond the diameter of the cylinder 47 and its end 95 has a part of the surface of the spherical part 39.
- the portions of the channels also enter the inserts 90. 49 passing through cylinder 47.
- a through slot 96 (Fig. 11) is formed in the form of a combination of symmetrically located rectangle and holes.
- the separator 7 (Fig.7) is made of two c-shaped parts, the connector 97 between which is made by the type of "protrusion in the groove”. On diametrically opposite places of one part there are protrusions 98, and on the other part of the groove 99.
- protrusion 98 Along the contour of the protrusion 98 there is a ⁇ -shaped groove 100, and chamfers along the contour of the groove 99.
- the protrusion 98 can move into the groove 99 in only one direction - along the axis 67 of the hinge connector 65.
- pins 101 are installed in the holes on the border of the protrusion 98 - groove 99.
- the thickenings 83 on the piston 6 can be transferred to one side of the piston 6, and the slots 81 to the other side of the piston 6.
- the thickening 83 and the slots 81 on one side of the piston 6 there will be a longer thickening 83.
- similar changes take place on the separator 7 (Fig.13).
- a thickening 70 and a slot 68 a longer thickening 70 is performed on one side of the separator 7, and a longer slot 68 is made on the other side of the separator 7 instead of a thickening 70 and slot 68.
- the piston 6 (Fig.14) is made in the form of a disk (and not a ring). Those. the cylinder 47 is part of the piston 6, and not the rotor 4. In this case, portions of the channels 49 also pass to the piston 6. When the piston 6 is rotated, the channels 49 partially overlap with the piston 6, but the passage area decreases in proportion to the decrease in the flow of the working fluid through them. To reduce the resistance to the working fluid, additional separate holes 102 were made on the piston 6 between the portions of the channels 49 for the passage of the working fluid passing through the channels 49. When the piston 6 is rotated, the holes 102 passing through the working fluid are replaced, but their total area does not change significantly. For greater strength piston 6 large holes on the piston corresponding to portions of the channels 49 can be replaced by a set of smaller holes 102. In the center of the piston 6, a hole 103 is made for the axis of the piston 6.
- the separator 7 consists of two approximately identical c-shaped parts of the ring, at the ends of each of which there are cylindrical rings 104, which are parts of the bulges 70, divided between the parts of the separator 7. On one c-shaped part of the separator 7 fall parts of the bulges 70 that are distant from its center , and on the other - close to the center. The plane dividing them is parallel to the ends 71.
- the cylindrical platform 82 on the piston 6 (Fig.16) is made on the liners 105 and enlarged in angular dimensions.
- the cross section of the liner 105 is a union of a circle sector with a small circle symmetrically located on the side external to the circle sector. Those. the insert 105 is obtained in the form of an arc with a cylindrical protrusion coaxial to it 106 from the outside.
- the piston 6 is first inserted into the rotor 4, then the c-shaped parts of the spacer 7 are connected around it, an axis 86 is inserted into the holes 72 of the rings 104 connecting them, and then the bushings 105 are inserted. Moreover, the axis 86, passing through two rings 104 and the hole 85 the piston 6, is pressed into only one of the rings 104 (preferably the second), or only into the hole 85 of the piston 6. The other ring 104 can rotate on the axis 86. The movable connection of the two parts of the separator 7 reduces the load on it in the weakest place - at the location hinge.
- Axis 86 perceives centrifugal forces acting on the parts of the separator 7 so that they do not lie on the friction pair. ORM does not lose working capacity even with wear or absence of axis 86. That is, to simplify the manufacture of parts of the separator 7 may not be attached to each other, and the connector 97 between them may be performed differently.
- inserts similar to the inserts 105 can be used. It is possible to reduce the forces exerted by the working fluid on the piston 6 and on the separator 7, as well as to increase their bearing surface by dividing the piston 6 / separator 7 into parts that are movable relative to each other.

- the separator 5 experiences a symmetrical load from the side of the working fluid on its inner part 60, which its external part 61 transfers to the ends 17 of the groove 15. Since the direction of this force is perpendicular to the speed of the separator 7, it does not transfer torque and energy between the rotor 4 and the working body.
- the piston 6 experiences a periodically centrally symmetrical load from the side of the working fluid to its external part 78, which it transfers to the ends 44 of the groove 43. Through the piston 6, energy and torque are transferred between the rotor 4 and the working fluid.

- the uncompensated torque is significantly weakened due to the distance between sections 37 and 38, which play the role of bearings.
- FIGS. 19-21 operates in a similar manner to the machine of FIG. 1.
- she has the opportunity to change her feed from the maximum one way to the same feed in the opposite direction with constant rotation of the rotor 4. This happens when the external control device rotates the rotary shafts of both steps in the angle range (for this example) from -25 degrees up to +25 degrees around 125 axes.

- the feed of the machine is almost uniform .
- the separator 5 experiences a periodic pulsating load moving from the side of the working fluid on its inner part 60, which its outer part 61 transfers to the ends 17 of the groove 15. Since the direction of this force is perpendicular to the speed of the separator 7, it does not transfer torque and energy between the rotor 4 and working fluid. An exception is the step differential pressure acting on the cross section of the separator 7, which pushes the separator 7 in the direction of its rotation.
- the piston 6 experiences a periodically centrally symmetrical load from the side of the working fluid to its external part 78, which it transfers to the ends 44 of the groove 43. Through the piston 6, energy and torque are transferred between the rotor 4 and the working fluid.
- the piston 6 through the hinge 89 transfers to the separator 7 a part of the energy of the rotor 4 to compensate for the friction forces acting on the separator 7 (mainly in the groove 15).

- the chamber 151 With an increase in the volume of the chamber 151, it is connected by a channel 48 to the entrance window 20 of the working fluid, and from the inlet pipe 21 through the windows 20 and 51/52, the working fluid enters it. With a decrease in the volume of chamber 152, it is connected by channel 48 to the exit window 23 of the working fluid, and the working fluid exits from it into the outlet pipe 24 through windows 23 and 51 / 52.
- cameras 151/152 reach the minimum or maximum volume, they are switched over with windows 20 , 23. The process is repeated for other chambers 152 / 153. Due to the phase shift between the pairs of chambers 152/153, the supply of ORM is close to uniform.
- the windows of the inlet 20 and the outlet 23 are connected with the working chambers 152, 153 through channels 48 made in the rotor 4, i.e. windows 20 and 23 do not directly exit into the working cavity 150. This makes it possible to maintain the working pressure in one step over the entire cycle of the machine (over the entire revolution of the rotor 4).
