[0003] Due to the structural limitations of existing rotating devices, if one wants to drive its rotor to rotate relative to the stator, the rotating device usually needs to be equipped with components such as an electric motor.

[0078] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In the detailed description below, many specific details are set forth in order to provide a comprehensive understanding of the present application. However, it will be apparent to those skilled in the art that the present application can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present application by illustrating examples of the present application. In the accompanying drawings and the following description, at least some of the well-known structures and technologies are not shown in order to avoid unnecessary ambiguity in the present application; and, for clarity, the sizes of some structures may be exaggerated. In addition, the features, structures, or characteristics described below may be combined in any suitable manner in one or more embodiments.

[0079] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of the rotary device and power source of this application. In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0080] In order to better understand this application, Figures 1 to 32 The rotating device and the power source according to the embodiments of the present application are described in detail.

[0081] like Figures 1 to 6As shown, the rotary device 100 provided in an embodiment of the present application includes a rotating assembly 10, a rolling element 20, and a flow restrictor 70. The rotating assembly 10 includes a rotor 11 and a stator 12 that are coaxially arranged and rotatably engaged. A receiving groove 13 is formed between the rotor 11 and the stator 12. The wall surface of the rotor 11 that encloses the receiving groove 13 is at least partially an arcuate surface 131, and the arcuate surface 131 is recessed in a direction away from the stator 12. The rolling element 20 is disposed in the receiving groove 13 and rolls with the arcuate surface 131 and the stator 12. The flow restrictor 70 is disposed in the receiving groove 13 and seals at least a portion of the side wall surface of the rolling element 20. The rolling element 20 and the flow restrictor 70 separate the accommodating groove 13 into a medium input chamber 13a and a medium output chamber 13b. Along the circumferential direction X of the rotor 11, the medium input chamber 13a and the medium output chamber 13b are distributed on both sides of the rolling element 20. The rotor 11 is provided with a guide channel 11a communicating with the medium input chamber 13a and a medium outlet 11b communicating with the medium output chamber 13b. The guide channel 11a can guide the external medium into the medium input chamber 13a, where it acts on the rolling element 20 and is then discharged from the medium outlet 11b through the medium output chamber 13b, thereby driving the rotor 11 to rotate relative to the stator 12.

[0082] Optionally, the rotor 11 and the stator 12 may be directly rotatably connected in a clearance fit manner.

[0083] Optionally, the rotor 11 and the stator 12 can be located inside the other. For example, the rotor 11 can be located inside the stator 12, so that the rotating assembly 10 has an inner rotor-outer stator structure. Of course, in some embodiments, the stator 12 can also be located inside the rotor 11, so that the rotating assembly 10 has an outer rotor-inner stator structure. In order to better understand the rotary device 100 provided in the embodiment of the present application, the following description of the rotating assembly 10 is based on an example in which the rotating assembly 10 has an inner rotor-outer stator structure.

[0084] Optionally, the rotor 11 may adopt a columnar structure, which may be cylindrical or prismatic.

[0085] Alternatively, the accommodating groove 13 can be recessed from the surface of the rotor 11 facing the stator 12 in a direction away from the stator 12. The shape of the recess on the rotor 11 for forming the accommodating groove 13 can be a groove form such as a U-shaped groove or a tapered groove.

[0086] Optionally, the wall surface of the rotor 11 enclosing the accommodating groove 13 includes a bottom wall surface and a side wall surface, the bottom wall surface is arranged facing the stator 12, and the arcuate surface 131 can be formed on the bottom wall surface. Optionally, the arcuate surface 131 is arranged to be concave in a direction away from the stator 12.

[0087] Optionally, the rolling element 20 may have a circular cross-sectional shape along the axial direction Y of the rotor 11 .

[0088] Optionally, the rolling element 20 may be clamped between the rotor 11 and the stator 12 and be in rolling engagement with the arcuate surface 131 and the stator 12 .

[0089] Optionally, in the circumferential direction X of the rotor 11 , the interface 11 f connecting the flow guide channel 11 a and the accommodating groove 13 and the medium outlet 11 b are distributed on both sides of the rolling body 20 .

[0090] Optionally, the guide channel 11 a may be directly or indirectly connected to an external device that provides a medium, so as to guide the medium to the receiving groove 13 and act on the rolling body 20 before being discharged from the medium outlet 11 b .

[0091] Optionally, the medium provided in the embodiment of the present application may be a fluid with good fluidity. The medium may be gas. Of course, liquid or solid like grease may also be used, as long as it can meet the driving requirements.

[0092] The rotary device 100 provided in the embodiment of the present application, when in use, can connect the guide channel 11a to a device capable of providing a medium.

[0093] like Figure 7 As shown, the medium is guided into the medium input chamber 13a of the receiving tank 13 via the flow channel 11a. As the medium enters the medium input chamber 13a and fills the medium input chamber 13a, the force exerted by the medium on the rolling element 20 is transmitted to the stator 12 and rotor 11, generating forces acting on the inner circumference of the stator 12 and the curved surface 131. In other words, the pressure exerted by the medium on the rolling element 20 is shared between the stator and rotor sides. The force exerted by the rolling element 20 on the inner circumference of the stator 12 does not affect the rotation of the rotor 11. The force exerted by the medium on the curved surface 131 via the rolling element 20 can be further divided into the friction force f between the rolling element 20 and the curved surface 131, and the pressure exerted by the rolling element 20 on the curved surface 131.

[0094] Due to the curvature of the curved surface 131, the line of action of the pressure exerted by the rolling element 20 on the curved surface 131 can pass through the center of the rotor 11, generating no torque. Alternatively, the line of action of the pressure exerted by the rolling element 20 on the curved surface 131 can pass approximately through the center of the rotor 11, generating minimal torque on the rotor 11. On the rolling element 20 side, the friction force f between the rolling element 20 and the curved surface 131 of the receiving groove 13 contributes to the rotation of the rotor 11. Meanwhile, the pressure of the medium also acts on the sidewalls and at least a portion of the bottom wall of the medium input chamber 13a, contributing to the rotation of the rotor 11. Some of the medium overflows through the gap on the rolling element 20 side into the medium output chamber 13b and is discharged from the medium outlet 11b. The medium output chamber 13b is not subjected to medium pressure.

[0095] As described above, after the medium enters the receiving tank 13, the primary factors affecting the rotation of the rotor 11 are the sidewall and bottom wall forces acting on the medium input chamber 13a, as well as the friction force f between the rolling element 20 and the curved surface 131. The combined force of the sidewall and bottom wall forces F is greater than the friction force between the rolling element 20 and the curved surface 131. Furthermore, the sidewall force F is located farther from the center of the rotor. In other words, the moment arm A1 of the sidewall force F is greater than the moment arm A2 of the friction force between the rolling element 20 and the curved surface 131. Due to the torque imbalance resulting from the combined force of the sidewall and bottom wall forces, as well as the friction force f between the rolling element 20 and the curved surface 131 (i.e., FA1 > fA2), the rotor 11 generates a rotational torque, thereby driving the rotor 11 in rotation relative to the stator 12.

[0096] The rotary device 100 provided in the embodiment of the present application has a receiving groove 13 enclosed between the rotor 11 and the stator 12, and the wall surface of the receiving groove 13 enclosed by the rotor 11 is at least partially in the form of an arcuate surface 131. The rolling element 20 is arranged in the receiving groove 13 and rollingly cooperates with the arcuate surface 131 and the stator 12. When the external medium enters the receiving groove 13 through the guide channel 11a and acts on the rolling element 20, it is discharged from the medium outlet 11b, converting the medium pressure into a driving force that causes the rotor 11 to rotate, thereby driving the rotor 11 to rotate relative to the stator 12. The device is minimally restricted by the environment, temperature, region, etc., and only needs to input the medium into the receiving groove 13. There is no need for equipment that provides high-speed medium, such as a blast furnace or water pump, nor is there a need for special equipment to convert thermal power, hydraulic power, wind power, nuclear energy or solar energy into electrical energy to drive the rotor 11. Therefore, the rotary device 100 is minimally restricted by the environment, temperature, and region, is easy to drive, and is not restricted by operating costs. It can replace turbines, electric motors, hydraulic motors, etc., and will not affect the environment, thus protecting the environment.

[0097] Optionally, the accommodating groove 13 is divided by the rolling body 20 to form a medium input chamber 13a and a medium output chamber 13b, and the positional relationship between each chamber, the guide channel 11a and the medium outlet 11b is limited, which is conducive to the entry of the medium and rapid pressurization, so as to facilitate the driving of the rotor 11 to rotate relative to the stator 12 by the rolling body 20.

[0098] like Figure 8 As shown, in some optional embodiments, the angle θ between the normal line aa of the rolling element 20 at the connection point on the arc surface 131 and the line bb connecting the rolling element 20 and the center of the rotor 11 is any value between 0 and 90°.

[0099] The rotating device 100 provided in the embodiment of the present application, through the above-mentioned arrangement, is conducive to making the torque generated by the combined force acting on the side wall surface and the bottom wall surface greater than the torque generated by the friction force f between the rolling body 20 and the arc surface 131, so that the rotor 11 generates a rotational torque, thereby facilitating driving the rotor 11 to rotate relative to the stator 12.

[0100] As an optional embodiment, the angle between the normal line of the connecting point of the rolling element 20 on the arc surface 131 and the line connecting the centers of the rolling element 20 and the rotor 11 is 0°.

[0101] Through the above arrangement, the pressure action line of the rolling body 20 on the arc surface 131 can pass through the center of the rotor 11 without generating torque, so that the medium entering the receiving groove 13 can drive the rotor 11 to rotate relative to the stator 12 with a relatively small pressure, thereby reducing the difficulty of driving the rotating device 100 and further reducing operating costs.

[0102] In some optional embodiments, the rolling element 20 of the rotary device 100 provided in the embodiments of the present application is cylindrical. Of course, the rolling element 20 may also be a sphere. The aforementioned structure of the rolling element 20 provides a smooth curved outer surface that mates with the rotor 11 and stator 12, thereby ensuring the required drive for the rotor 11. Furthermore, this arrangement reduces the frictional resistance of the rolling element 20 on the rotor 11 during rotation.

[0103] Continue reading Figures 1 to 8 As shown, as an optional embodiment, the rotating device 100 provided in the embodiment of the present application, the flow limiting portion 70 includes a first flow limiting component 30, and the rotating component 10 is respectively provided with a first flow limiting component 30 on both sides of its own axial direction Y. The first flow limiting component 30 is connected to the rotor 11 and its positive projection on the axial direction Y of the rotating component 10 at least partially covers the accommodating groove 13.

[0104] Optionally, the first flow limiting component 30 and the rotor 11 may be connected to each other by a fixed connection such as welding. Of course, they may also be connected to each other by a detachable connection such as bolts.

[0105] Optionally, an end surface of the first flow limiting component 30 in the radial direction of the rotor 11 may abut against the stator 12 to ensure the sealing of the accommodating groove 13 .

[0106] The rotary device 100 provided in the embodiment of the present application can seal the medium entering the receiving groove 13 by respectively providing a first flow limiting component 30 at both ends of the rotating component 10 on the axial direction Y, thereby reducing the probability of leakage and ensuring the driving effect of the medium on the rotation of the rotor 11 relative to the stator 12.

[0107] like Figure 1 、 Figure 2 as well as Figures 9 to 12 As shown, in some optional embodiments, the rotary device 100 provided in the embodiment of the present application, the first flow limiting component 30 includes a flow limiting plate 31 and a first elastic member 32, the flow limiting plate 31 is connected to the rotor 11, and the first elastic member 32 is connected to the flow limiting plate 31 and abuts against the side wall surface of the stator 12 and the rolling body 20.

[0108] Optionally, the shape of the flow limiting plate 31 may match the shape of the cross section of the accommodating groove 13 in the axial direction Y of the rotor 11 , and the size of the flow limiting plate 31 may be larger than the size of the accommodating groove 13 .

[0109] Optionally, the flow limiting plate 31 may be connected to the rotor 11 by welding, bolts or other connection methods.

[0110] Optionally, one end of the first elastic member 32 in the radial direction of the rotating assembly 10 may partially abut against the stator 12 , optionally against the wall of the stator 12 facing the rotor 11 , and may also partially abut against the rolling element 20 .

[0111] In the rotary device 100 provided in the embodiment of the present application, the first flow-limiting component 30 includes a flow-limiting plate 31 and a first elastic member 32. The flow-limiting plate 31 ensures connection with the rotor 11 and ensures that the accommodating slot 13 is sealed in the axial direction Y of the rotor 11. Furthermore, by providing the first elastic member 32 and connecting it to the flow-limiting plate 31 so as to abut against the stator 12 and the rolling element 20, the medium can be prevented from flowing out of the gap between the rotor 11 and the stator 12, thereby ensuring sealing performance for the medium.

The first elastic member 32 may also include a mating portion with the rolling body 20, which is located on the side of the limiting plate 31 facing the rolling body 20 in the axial direction Y of the rotating assembly 10, so as to at least ensure the sealing performance of the medium input chamber 13a, and thereby ensure the driving requirement for the rotor 11 to rotate relative to the stator 12.

[0115] In some optional embodiments, in the rotary device 100 provided in the embodiment of the present application, in the rotating assembly 10, the number of the accommodating slots 13 formed by the rotor 11 and the stator 12 can be one, or of course can be more than two.

[0116] Optionally, when there are more than two accommodating grooves 13 , the more than two accommodating grooves 13 are spaced and evenly distributed in the circumferential direction X of the rotating assembly 10 , a rolling body 20 is provided in each accommodating groove 13 , and the guide channel 11 a is connected to each accommodating groove 13 .

This allows the rotor 11 to be subjected to force from multiple points, thereby reducing the difficulty of driving the rotor 11. Furthermore, by evenly disposing the two or more receiving slots 13 in the circumferential direction X of the rotating assembly 10, the uniformity of the force applied to the rotor 11 can be ensured, ensuring smooth rotation of the rotor 11 relative to the stator 12.

[0121] Continue reading Figures 1 to 12 As shown, as an optional implementation, in the rotary device 100 provided in the embodiment of the present application, a connecting port 11 c is provided on the rotor 11 , and the connecting port 11 c is communicated with the guide channel 11 a .

[0122] Optionally, the guide channel 11a may include flow channel units equal in number to the receiving grooves 13 and arranged in a one-to-one correspondence, one end of each flow channel unit is connected to the receiving groove 13, and the other end converges to the connecting port 11c to obtain the medium through the connecting port 11c.

[0123] The rotary device 100 provided in the embodiment of the present application provides a connecting port 11c on the rotor 11, and connects the connecting port 11c to the guide channel 11a, thereby facilitating the medium to directly enter the receiving groove 13 through the guide channel 11a inside the rotor 11, thereby reducing the number of pipelines corresponding to and connected to the receiving groove 13, simplifying the structure of the rotary device 100, and avoiding the risk of interference or entanglement caused by the multiple pipeline settings during the rotation of the rotor 11.

[0124] Optionally, the number of the connecting port 11c may be one, and the connecting port 11c may be provided at the center of the rotor 11. The lengths of the medium flow paths from the connecting port 11c to the respective receiving grooves 13 may also be made the same.

[0125] Through the above arrangement, the flow rate and flow rate of the medium entering each receiving groove 13 can be ensured to be equal or approximately equal, so that the force exerted by each rolling body 20 on the rotor 11 is roughly the same, which can ensure the smooth performance of the rotor 11 when rotating relative to the stator 12.

[0126] It can be understood that, in the rotary device 100 provided in the embodiment of the present application, the device for providing the medium to the flow guide channel 11a can be an external component. Of course, this is an optional method.

[0127] like Figure 13 As shown, in some embodiments, the rotary device 100 provided in the embodiment of the present application may further include a main pressurizing component 50, which is connected to the guide channel 11a through the connecting port 11c and can provide or recover the medium to the guide channel 11a.

[0128] Optionally, the main pressurizing component 50 can be used to provide a medium into the guide channel 11 a so that the medium can enter the receiving groove 13 through the guide channel 11 a and act on the rolling body 20 to drive the rotor 11 to rotate through the rolling body 20 .

[0129] Optionally, when other components provide medium into the containing tank 13 , the main pressurizing component 50 can also be used to recover the medium.

[0130] Optionally, the rotary device 100 further includes a first pipeline 51 , and the main pressurizing component 50 can be indirectly connected to the connecting port 11 c through the first pipeline 51 .

[0131] In some optional embodiments, the connecting port 11c may be provided with a first bearing (not shown), the first bearing including a first inner ring and a first outer ring that are rotatably fitted and dynamically sealed, the first inner ring being connected to the first pipeline 51, and the first outer ring being connected to the rotor 11. Through the above arrangement, the connection requirements between the rotor 11 and the first pipeline 51 under rotating conditions can be guaranteed, the medium can enter the guide channel 11a under the condition of the rotation of the rotor 11, and the first pipeline 51 can be prevented from being entangled when rotating with the rotor 11, thereby improving safety performance.

[0132] The rotary device 100 provided in the embodiment of the present application can accommodate a medium in the main pressurizing component 50 by setting a main pressurizing component 50, and control the timing and volume of the medium entering the guide channel 11a by opening and closing the control valve to meet the driving requirements for the rotation of the rotor 11 relative to the stator 12.

[0133] Alternatively, when the main pressurizing component 50 is used to supply medium into the flow channel 11a through the connection port 11c, the medium entering the receiving groove 13 can be directly discharged through the medium outlet 11b after acting on the rolling element 20 and driving the rolling element 20 to rotate. Of course, this is an optional embodiment, but is not limited to the above method.

[0134] like Figures 14 to 16 As shown, in some optional embodiments, a collecting channel 11e can be further provided on the rotor 11 of the rotary device 100, and the collecting channel 11e is connected to the medium output chamber 13b.

[0138] The rotary device 100 provided in the embodiment of the present application can be used to recover the medium by providing a collecting channel 11e and an auxiliary pressure component 60. In addition, the above-mentioned arrangement enables the collecting channel 11e to guide the medium in the auxiliary pressure component 60 to the medium output chamber 13b to act on the rolling body 20, and drive the rotor 11 to rotate relative to the stator 12 through the rolling body 20. In addition, the guide channel 11a can also guide the medium in the receiving groove 13 after being used to drive the rolling body 20 into the main pressure component 50. In other words, the arrangement of the auxiliary pressure component 60 and the collecting channel 11e enables the rotary device 100 to not only drive the rotor 11 to rotate forward relative to the stator 12 through the main pressure component 50, but also allow the medium to overflow into the medium output chamber 13b as the rotor 11 rotates, and then be sucked into the auxiliary pressure component 60 through the collecting channel 11e for recovery. Of course, the auxiliary pressurizing component 60 can also be used to deliver medium to drive the rotor 11 to rotate reversely relative to the stator 12. The medium can then overflow to 13a as the rotor 11 rotates, pass through the guide channel 11a, and be sucked into the main pressurizing component 50 for recovery. This ensures that the rotor 11 can rotate forward and reverse relative to the stator 12 in accordance with the requirements.

The second bearing includes a second inner ring and a second outer ring that are rotationally engaged and dynamically sealed.

This arrangement ensures both the flow of the medium and the connection between the rotor 11 and the second pipeline 61 during rotation, preventing the second pipeline 61 from becoming entangled as the rotor 11 rotates, thereby improving safety.

[0151] The rotary device 100 provided in the embodiment of the present application has a rotor 11 adopting the above-mentioned structural form, which can also meet the installation requirements of the rolling element 20 and the need to use the medium to act on the rolling element 20 to drive itself to rotate relative to the stator 12.

Exemplarily, the second flow limiting component 40 can be arranged around part of the rolling element 20, the medium input chamber 13a is located in the second flow limiting component 40 and the medium output chamber 13b is located outside the second flow limiting component 40.

In some optional embodiments, the annular frame 41 may be in the shape of a rectangular ring.

[0162] Optionally, the annular frame 41 can be an integrated structure, or of course a split structure.
