It will be apparent, however, to one skilled in the art that the present application may be practiced 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 thereof. In the drawings and the following description, at least some well-known structures and techniques have not been shown in detail in order to avoid unnecessarily obscuring the present application; also, the dimensions of some of the structures may be exaggerated for clarity. Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

The following description will be given with the directional terms as they are shown in the drawings, and not with the specific configuration of the swing device and the power source of the present application. In the description of the present application, it is also to be noted that, unless otherwise explicitly specified or limited, the terms "mounted" and "connected" are to be interpreted broadly, e.g., as being either fixedly connected, detachably connected, or integrally connected; can be directly connected or indirectly connected. The specific meaning of the above terms in the present application can be understood as appropriate by one of ordinary skill in the art.

For a better understanding of the present application, a swing device and a power source according to an embodiment of the present application will be described in detail below with reference to fig. 1 to 32.

As shown in fig. 1 to 6, a rotating device 100 provided in an embodiment of the present application includes a rotating assembly 10, a rolling element 20, and a flow restrictor 70, where the rotating assembly 10 includes a rotor 11 and a stator 12 that are coaxially disposed and rotationally fit, an accommodating groove 13 is formed between the rotor 11 and the stator 12, a wall surface of the accommodating groove 13 enclosed by the rotor 11 is at least partially an arc surface 131, and the arc surface 131 is recessed toward a direction away from the stator 12. The rolling elements 20 are disposed in the accommodating groove 13 and are in rolling engagement with the arc-shaped surface 131 and the stator 12. The restrictor 70 is provided in the accommodation groove 13 and sealingly engages with the sidewall surface of at least some of the rolling elements 20. The rolling body 20 and the flow restrictor 70 separate the receiving groove 13 to form a medium input chamber 13a and a medium output chamber 13b, the medium input chamber 13a and the medium output chamber 13b are distributed on two sides of the rolling body 20 along the circumferential direction X of the rotor 11, the rotor 11 is provided with a flow guide channel 11a communicated with the medium input chamber 13a and a medium outlet 11b communicated with the medium output chamber 13b, and the flow guide channel 11a can guide an external medium to the medium input chamber 13a, act on the rolling body 20, and then discharge the external medium from the medium outlet 11b through the medium output chamber 13b to drive the rotor 11 to rotate relative to the stator 12.

Alternatively, the rotor 11 and the stator 12 may be directly connected in a clearance fit manner.

Alternatively, the rotor 11 and the stator 12 may be located inside one another, and illustratively, the rotor 11 may be located inside the stator 12, so that the rotating assembly 10 is in the form of an inner rotor-outer stator structure. Of course, in some embodiments, the stator 12 may be located inside the rotor 11, such that the rotating assembly 10 is in the form of an outer rotor-inner stator structure. For a better understanding of the turning device 100 provided in the embodiments of the present application, the present application will be exemplified below with the rotating assembly 10 being an inner rotor-outer stator structure.

Alternatively, the rotor 11 may have a columnar structure, which may have a cylindrical shape, a prismatic shape, or the like.

Alternatively, the receiving groove 13 may be recessed from the surface of the rotor 11 facing the stator 12 in a direction away from the stator 12. The recess of the rotor 11 for forming the accommodation groove 13 may be shaped in the form of a U-shaped groove, a tapered groove, or the like.

Alternatively, the wall surface of the rotor 11 that surrounds the accommodation groove 13 includes a bottom wall surface that is disposed facing the stator 12, and a side wall surface, and the arc surface 131 may be formed on the bottom wall surface. Optionally, the arc-shaped surface 131 is concavely arranged in a direction away from the stator 12.

Alternatively, the cross-sectional shape of the rolling elements 20 in the axial direction Y of the rotor 11 may be circular.

Alternatively, the rolling bodies 20 may be sandwiched between the rotor 11 and the stator 12 and in rolling engagement with the arc-shaped face 131 and the stator 12.

Alternatively, in the circumferential direction X of the rotor 11, the interface 11f, at which the flow guide channel 11a communicates with the accommodation groove 13, and the medium outlet 11b are distributed on both sides of the rolling elements 20.

Alternatively, the flow guide channel 11a may be directly or indirectly connected to an external device for supplying a medium, so that the medium is guided to the accommodating groove 13 and discharged from the medium outlet 11b after acting on the rolling elements 20.

Alternatively, the medium provided in this embodiment may be a fluid with good fluidity, and the medium may be a gas, or may be a liquid or a solid similar to grease, as long as the driving requirement is met.

When the turning device 100 provided by the embodiment of the application is used, the flow guide channel 11a can be communicated with equipment capable of providing media.

As shown in fig. 7, the medium is guided into the medium input chamber 13a of the accommodating groove 13 through the guide passage 11a, and as the medium entering the medium input chamber 13a increases, when the medium input chamber 13a is filled with the medium, the acting force of the medium on the rolling element 20 is transmitted to the stator 12 and the rotor 11 on the rolling element 20 side, and the acting force on the inner circumferential surface and the arc-shaped surface 131 of the stator 12 is generated. That is, the pressure of the medium acting on the rolling elements 20 is shared between the stator side and the rotor side. The force of the rolling elements 20 on the inner circumferential surface of the stator 12 does not affect the rotation of the rotor 11. The acting force of the medium on the arc surface 131 by the rolling body 20 can be divided into: the friction force f between the rolling element 20 and the arc surface 131 and the pressure of the rolling element 20 against the arc surface 131.

Due to the curvature of arc surface 131, the line of pressure action of rolling element 20 on arc surface 131 may pass through the center of rotor 11, and no torque may be generated, or the line of pressure action of rolling element 20 on arc surface 131 may pass through the center of rotor 11 approximately, and the torque generated on rotor 11 may be extremely small. On the rolling element 20 side, a frictional force f between the rolling element 20 and the arc-shaped surface 131 of the housing groove 13 acts on the rotation of the rotor 11. On the other hand, the pressure of the medium also acts on the side wall surface and at least a part of the bottom wall surface of the medium input chamber 13a, acting on the rotation of the rotor 11. Part of the medium overflows to the medium discharge chamber 13b through the gap on the rolling element 20 side and is discharged from the medium outlet 11b, and the medium discharge chamber 13b is not subjected to the medium pressure.

As described above, the main factors influencing the rotation of the rotor 11 after the medium enters the housing groove 13 are the side wall surface acting force and the bottom wall surface acting force of the medium acting on the medium feeding chamber 13a, and the friction force f between the rolling body 20 and the arc surface 131. The acting force F on the side wall surface and the acting force sum of the bottom wall surface are larger than the friction force between the rolling body 20 and the arc-shaped surface 131, and the acting force F on the side wall surface is farther away from the center of the rotor, that is, the force arm A1 of the acting force F on the side wall surface is larger than the force arm A2 of the friction force between the rolling body 20 and the arc-shaped surface 131. The rotor 11 generates a turning torque due to a torque imbalance, i.e., FA1 > FA2, between a resultant force of the side wall surface force F and the bottom wall surface force F and a frictional force F between the rolling element 20 and the arc surface 131, thereby driving the rotor 11 to rotate relative to the stator 12.

The embodiment of the application provides a rotary device 100, because it is formed with holding tank 13 to enclose to close between rotor 11 and the stator 12, and rotor 11 encloses to close the wall that forms holding tank 13 and at least part is arcwall face 131, rolling element 20 sets up in holding tank 13 and with arcwall face 131 and stator 12 roll fit, make and discharge by medium export 11b behind external medium gets into holding tank 13 and acts on rolling element 20 through water conservancy diversion passageway 11a, convert medium pressure into rotor 11 can pivoted power, rotate for stator 12 in order to drive rotor 11, receive the environment, the temperature, region etc. restriction is minimum, only need to input the medium in holding tank 13 can, the equipment that need not provide high-speed medium is like the blast furnace, water pump etc., also need not have special equipment to turn into the electric energy with firepower, water conservancy, wind-force, nuclear energy or solar energy etc. and drive rotor 11. Therefore, the slewing device 100 is advantageous for driving while being minimally restricted by the environment, temperature, and region, is not restricted by the running cost, can replace a turbine, an electric motor, a hydraulic motor, and the like, and is environmentally friendly without affecting the environment.

Optionally, the accommodating groove 13 is partitioned by the rolling bodies 20 to form a medium input chamber 13a and a medium output chamber 13b, and the positional relationship between each chamber and the flow guide channel 11a and the medium outlet 11b is defined, so that the medium can enter and be rapidly pressurized, and the rotor 11 can be driven to rotate relative to the stator 12 by the rolling bodies 20.

As shown in fig. 8, in some alternative embodiments, an angle θ between a normal aa of the junction of rolling element 20 on arc surface 131 and a connecting line bb between rolling element 20 and a center of rotor 11 is any value between 0 ° and 90 °.

Through the above arrangement, the turning device 100 provided in the embodiment of the present application is beneficial to making the resultant force of the acting force acting on the side wall surface and the acting force acting on the bottom wall surface generate a moment greater than the moment generated by the friction force f between the rolling element 20 and the arc-shaped surface 131, so that the rotor 11 generates a turning torque, and thus, the rotor 11 is beneficial to being driven to rotate relative to the stator 12.

As an alternative embodiment, the angle between the normal of rolling element 20 at the junction on arc surface 131 and the line connecting rolling element 20 and the center of rotor 11 is 0 °.

Through the arrangement, the pressure action line of the rolling body 20 on the arc surface 131 passes through the center of the rotor 11, no torque is generated, the rotor 11 can be driven to rotate relative to the stator 12 by the small pressure of the medium entering the accommodating groove 13, the driving difficulty of the slewing device 100 is reduced, and the operation cost is further reduced.
