Description

Technical Field

[0001] The present invention relates to the technical field of static disk torque measurement devices, and more particularly to a measurement device and method for the wind resistance torque of a static disk. Background Art

[0002] Currently, in modern aero-engines or other power machinery, high-speed rotor components are included. These high-speed rotor components will generate viscous friction resistance with the static disk under working conditions. At the same time, protrusions such as bolts and rivets on the surface of the static disk will also generate pressure difference resistance and friction resistance when interacting with the fluid during high-speed movement. These resistances cause torque loss of the static disk, and accurate measurement of this type of torque is required during research.

[0003] The current static disk torque measurement device has significant defects: during the measurement process, the friction between the rotor and the static disk and air, as well as the eddy current effect, cause energy loss and generate wind resistance torque. This energy loss is converted into heat energy, significantly increasing the temperature of the static disk, which may then lead to thermal damage.

[0004] However, it is difficult for the existing device to achieve efficient heat dissipation of the static disk during measurement, and the accumulation of heat has become a key factor affecting measurement accuracy and equipment reliability. This indicates that there is a bottleneck in the existing technology in terms of thermal management, which limits its performance in high-precision and long-term measurement applications. Summary of the Invention

[0005] The present application provides a measurement device and method for the wind resistance torque of a static disk, which has the function of efficiently dissipating heat from the static disk.

The output end of the static torque measuring instrument is connected to the static disk through a coupling. The fixing member includes two relatively sliding sliders and clamping blocks corresponding to the sliders. A clamping groove and a matching heat dissipation column are arranged in the clamping block. The matching heat dissipation column is slidably fitted to the inner wall of the clamping groove and contacts the surface of the static disk.

[0007] Preferably, the clamping block is of a semi-circular arc structure, and a clamping groove matching the outer surface of the static disk is formed on its inner surface. The matching heat dissipation columns are distributed circumferentially along the clamping groove and are slidably fitted with the clamping block. The cross-section of the matching heat dissipation column is elliptical.

[0008] Preferably, a unidirectional extension layer is provided on the inner surface of the adapted heat dissipation column. The unidirectional extension layer includes a plurality of tapered barbs, and the deformation angle of the tapered barbs is 30°, and the tip is tangent to the surface of the static disk.

[0009] Preferably, the outer end of the adapted heat dissipation column is connected to an elastic threaded strip, and the other end of the elastic threaded strip is fixed to the inner wall of the limiting housing. The limiting housing and the clamping block form a heat conduction cavity, and a heat conduction medium is filled in the heat conduction cavity.

[0010] Preferably, a heat conduction fiber extends from the end of the adapted heat dissipation column. The heat conduction fiber penetrates through the adapted heat dissipation column and contacts the inner cavity of the elastic threaded strip.

[0011] Preferably, the heat conduction cavity between the limiting housing and the clamping block is sealed. The heat conduction medium is heat-conducting silicone grease and is filled in the inner space of the cavity.

[0012] Preferably, a number of heat conduction rings are coaxially arranged inside the elastic threaded strip. The heat conduction rings are made of graphene. A mesh heat insulation film is arranged on the outer surface of the elastic threaded strip, and the heat insulation film is made of aluminum foil.

[0013] Preferably, the slider of the fixing member slides in the chute of the base. A cooling assembly is arranged inside the limiting housing. The cooling assembly includes a cooling cavity communicated with the inner cavity of the elastic threaded strip. The cooling cavity is provided with a coolant input end and a heat exchange output end.

[0014] Preferably, the coolant input end is connected with a boosting assembly. The boosting assembly includes a boosting housing. A driving motor is fixedly installed on the outer surface of the boosting housing. The output end of the driving motor is connected with a first gear. A second gear is meshed with one side of the first gear, and rotating shafts are fixedly installed on the central axes of the first gear and the second gear. The rotating shafts penetrate through the inside of the boosting housing and are connected with boosting guide vanes. The boosting guide vanes are of an S-shaped structure.

[0015] Preferably, a method for measuring the wind resistance torque of a static disk, based on the above-mentioned measuring device for the wind resistance torque of a static disk, the measuring steps include: S1: Static disk encircling and clamping: By adjusting the slider spacing, the clamping block slot is brought into contact with the surface of the static disk, and the position of the slider is fixed by bolts to achieve the encircling clamping of the static disk; S2: Cooling circulation system construction: The coolant pump is connected to the coolant input end of the limiting housing, and the radiator is connected to the heat exchange output end to form a coolant circulation loop for cooling the static disk; S3: Coolant boosting drive: The driving motor drives the first gear, and the first gear drives the second gear and the rotating shaft to rotate, thereby driving the pressurizing and guiding blades; the S-shaped pressurizing and guiding blades push the coolant to increase the flow rate and pressure of the coolant; S4: Torque measurement and control: The driving motor drives the rotor to rotate, generating an air resistance torque acting on the static disk; the static torque measuring instrument measures this torque value and transmits the data to the controller, and the controller processes and displays the data to obtain the static disk torque data.

[0016] In summary, the present application has the following beneficial effects: 1. Using the driving motor as the power source to drive the rotor to rotate. The rotation speed and direction of the rotor are controllable. When the rotor rotates on the static disk, it will generate air flow, thereby generating an air resistance torque acting on the static disk. This torque is transmitted to the static torque measuring instrument through the static disk. The static torque measuring instrument accurately measures the torque value received by the static disk and transmits the data to the controller. The controller receives the data from the static torque measuring instrument, processes, displays and obtains the measurement data. The measurement data is used to analyze the aerodynamic performance of the static disk, optimize the design, reduce wind resistance and improve efficiency.

[0017] 2. The slidable adapter heat dissipation posts can be adjusted according to the convex parts on the surface of the static disk to fill the gap between the card slots and the static disk, ensuring more comprehensive contact between the clamping blocks and the surface of the static disk; thus, it can be used to adapt to static disks of different shapes.

[0018] 3. By integrating a unidirectional extension layer on the inner wall of the heat dissipation post, its microscopic structure is like the barbs on the surface of a cat's tongue, which is composed of a large number of conical barbs arranged in a matrix. The key characteristic of these conical barbs is that their unidirectional deformation ability can only bend in one direction. It allows the static disk to rotate flexibly in one direction, while providing a strong locking force in the other direction to prevent accidental loosening. The magnitude of the locking force is proportional to the magnitude of the clockwise torque, which means that the locking effect is self-adaptive. The greater the torque, the tighter the locking, thus providing extremely high reliability and stability.

[0019] 4. Connect the coolant input end of the limit housing to the coolant pump to inject coolant into the cooling chamber; and connect the heat exchange output end to an external radiator to discharge the coolant after absorbing heat, forming a cycle for cooling the static disk. Further, powered by the driving motor, it drives the first gear to rotate; the first gear drives the second gear and the rotating shaft to rotate, enabling the pressurizing and guiding blades. When the pressurizing and guiding blades rotate, the S-shaped structure will push the coolant to further increase the flow rate and pressure of the coolant. Description of the Drawings

[0023] The present invention discloses a device and a method for measuring the wind resistance torque of a static disc, as shown in Figure 1 and Figure 2As shown in the figure, the measuring device for the wind resistance torque of the static disk 6 includes a base 1. On the upper surface of the base 1, there are a driving motor 2, a fixing member 3 for fixing the static disk 6, a static torque measuring instrument 4 for measuring the wind resistance torque of the static disk 6, and a controller for controlling the static torque measuring instrument 4. Among them, the output end of the driving motor 2 is connected to a rotor 5 arranged on the static disk 6 to drive the rotor 5 so that the rotor 5 rotates coaxially on the static disk 6, and the static disk 6 is connected to the output end of the static torque measuring instrument 4.

[0024] As Figure 1 and Figure 2 shown in the figure, specifically, during the detection process, the driving motor 2 serves as a power source to drive the rotation of the rotor 5. The rotation speed and direction of the rotor 5 are controllable. When the rotor 5 rotates on the static disk 6, it will generate air flow, and then generate a wind resistance torque acting on the static disk 6. This torque is transmitted to the static torque measuring instrument 4 through the static disk 6. The static torque measuring instrument 4 accurately measures the torque value received by the static disk 6 and transmits the data to the controller. The controller receives the data from the static torque measuring instrument 4, processes, displays it, and may control the driving motor 2 according to the set rotation speed or other parameters to achieve the measurement of wind resistance torque under different working conditions.

[0025] As Figure 1 and Figure 2 shown in the figure, the controllable rotation speed provided by the driving motor 2 can simulate different working conditions to study the variation law of wind resistance torque with parameters such as rotation speed. The measurement data can be used to analyze the aerodynamic performance of the static disk 6, optimize the design, reduce wind resistance, and improve efficiency.

[0026] As Figure 2 shown in the figure, the output end of the static torque measuring instrument 4 is connected to the static disk 6 through a coupling 7, and the coupling 7 is coaxially connected to the static disk 6; the main function of the coupling 7 is to transmit torque. The wind resistance torque from the static disk 6 is transmitted to the sensor of the static torque measuring instrument 4 without loss through the coupling 7.

[0027] As Figure 3 shown in the figure, the driving motor 2 is fixed in a bracket on the base 1, so as to play the role of fixing the bracket.

[0028] As Figure 3 and Figure 4 shown in the figure, there are two fixing members 3. The fixing member 3 includes a chute 301 opened on the upper surface of the base 1. In the chute 301 of the base 1, there are two slidable sliders 302 relative to each other. On the upper surface of the slider 302, there is a clamping block 303. Specifically, the clamping block 303 is a semi-circular structure, and an arc-shaped clamping groove 304 is provided on the inner surface of the clamping block 303, and the clamping groove 304 matches the outer surface of the static disk 6.

[0029] As shown in Figure 3 and Figure 4 As shown, through the semi-circular clamping blocks 303 on two relatively sliding sliders 302, a surrounding clamping of the outer surface of the static disk 6 is formed. By using frictional force and contact area, reliable fixation of the static disk 6 is achieved. The relative sliding of the slider 302 within the chute 301 allows adjustment of the distance between the two clamping blocks 303, thereby accommodating static disks 6 of different diameters or sizes. By rotating the bolt provided within the slider 302, the spacing between the two clamping blocks 303 can be adjusted and fixed. The card slot 304 matches the arc of the outer surface of the static disk 6, ensuring a large-area contact between the clamping block 303 and the static disk 6, evenly dispersing the clamping force, avoiding concentrated stress, and protecting the surface of the static disk 6.

[0030] As shown in Figure 3 and Figure 4 As shown, the sliding design of the slider 302 enables this fixing structure to accommodate static disks 6 of different sizes, improving versatility and flexibility. The symmetrical design of the two clamping blocks 303 and the matching of the card slot 304 with the surface of the static disk 6 ensure that the static disk 6 is firmly fixed on the base 1, preventing loosening or displacement.

[0031] As shown in Figure 3 and Figure 4 As shown, two rows of heat dissipation holes 8 are provided inside the arc-shaped card slot 304 of the clamping block 303. The two rows of the heat dissipation holes 8 are evenly distributed at equal angles around the central axis of the card slot 304. A slidable adaptive heat dissipation column 9 is provided inside the heat dissipation hole 8. Due to the uneven convex portions on the surface of the static disk 6, relying solely on the card slot 304 with an arc-shaped structure will result in poor adaptability for fixing the static disk 6. Therefore, through the sliding of the slidable adaptive heat dissipation column 9, the static disk 6 with a special-shaped structure can be well fixed inside the clamping block 303.

[0032] Specifically, as shown in Figure 3 and Figure 4 As shown, the slidable adaptive heat dissipation column 9 can be adjusted according to the convex portions on the surface of the static disk 6 to fill the gap between the card slot 304 and the static disk 6, ensuring more comprehensive contact between the clamping block 303 and the surface of the static disk 6. Through the contact between the adaptive heat dissipation column 9 and the convex portions, the total contact area between the clamping block 303 and the static disk 6 is increased, thereby improving the fixing effect. The adaptive heat dissipation column 9 can disperse the clamping force, avoid the clamping force concentrating on a few points, and reduce the risk of deformation of the static disk 6.

[0033] As shown in Figure 3 [[ID=3I]]and Figure 4As shown, in addition, the energy loss caused by the wind resistance torque between the stationary disk 6 and the rotor 5 will be converted into heat. The design of the heat dissipation holes 8 and the heat dissipation columns helps to dissipate the heat, preventing the stationary disk 6 from being affected in performance or damaged due to excessive temperature during use.

[0034] As Figure 5 shown, the cross-section of the adapted heat dissipation column 9 is an elliptical structure. The difference between the major axis and the minor axis of the elliptical cross-section can better adapt to the protrusions of different shapes and sizes. During the sliding process, the elliptical cross-section can provide more contact points and contact areas, thereby improving the adaptability. When the elliptical cross-section is stressed, its edge part is more likely to deform, thus increasing the friction force with the protrusions on the surface of the stationary disk 6, helping to improve the fixing effect and preventing the stationary disk 6 from sliding.

[0035] As Figure 5 shown, moreover, the end face of the elliptical structure is convenient for sliding compared with other corner cross-sections, avoiding jamming during the process of the adapted heat dissipation column 9 fitting the surface of the stationary disk 6.

[0036] As Figure 5 shown, and the material of the adapted heat dissipation column 9 is beryllium copper alloy, which has high hardness, good wear resistance, and good heat conduction effect.

[0037] As Figure 5 shown, a unidirectional extension layer 10 is provided on the inner surface of the adapted heat dissipation column 9. The unidirectional extension layer 10 includes a number of unidirectional conical barbs arranged in an array. Among them, the conical barbs are unidirectionally deformed, and the unidirectional deformation angle is 30°, and the conical barbs are tangent to the surface of the stationary disk 6.

[0038] As Figure 5 shown, a unidirectional extension layer 10 is integrated on the inner wall of the heat dissipation column. Its micro-structure is like the barbs on the surface of a cat's tongue, which is composed of a large number of conical barbs arranged in a matrix. The key characteristic of these conical barbs is their unidirectional deformation ability, which can only bend in one direction. Specifically, the deformation angle of each conical barb is precisely controlled at 30°, and in the initial state, its tip is tangent to the surface of the stationary disk 6, forming a pre-tightening force.

[0039] As Figure 5 shown, when the stationary disk 6 is subjected to a clockwise torque, its surface comes into contact with the side surface of the conical barb. Due to the unidirectional deformation characteristic of the barb, this contact force will force the barb to open in the preset direction, similar to the barb of a fishhook hooking an object. This opening not only increases the contact area, but also converts the torque of the stationary disk 6 into the expansion force of the barb, thus significantly enhancing the fixing effect and effectively preventing the further rotation of the stationary disk 6.

[0040] As Figure 5As shown, when static disk 6 is subjected to counterclockwise torque, its surface slides "following" the direction of the barbs. The conical barbs are not hindered and naturally return to their original tangent position. This design makes the counterclockwise movement of static disk 6 very smooth and easy, with virtually no resistance.

[0041] like Figure 5 As shown, this unidirectionally extendable layer 10 achieves a "one-direction-only" locking function, allowing the stator plate 6 to rotate flexibly in one direction while providing a strong locking force in the other direction to prevent accidental loosening. The locking force is proportional to the clockwise torque, meaning the locking effect is adaptive. Greater torque results in tighter locking, providing extremely high reliability and stability.

[0042] like Figure 5 As shown, the tapered barbs are made of a graphene-polymer composite material, which offers excellent thermal conductivity and flexibility. The microstructural design of the tapered barbs ensures precise and controllable deformation. The 30° deformation angle and the elastic properties of the material ensure that the barbs reliably open when stressed and quickly retract when unstressed.

[0043] like Figure 6 As shown, the outer ring of the clamping block 303 is fixed with a limiting shell 11. The limiting shell 11 is an arc-shaped structure. The function of the limiting shell 11 is to limit the movement range of the adaptive heat dissipation column 9. A heat conduction cavity is formed between the inner ring of the limiting shell 11 and the outer ring of the clamping block 303. The heat conduction cavity is key. It transfers heat to the adaptive heat dissipation column 9 through the clamping block 303. The interior of the heat conduction cavity is filled with a heat conduction medium, which is thermal grease here to improve the heat dissipation efficiency of the adaptive heat dissipation column 9. The outer end of the adaptive heat dissipation column 9 passes through the heat dissipation hole 8 and is connected to an elastic threaded strip 12. One end of the elastic threaded strip 12 is connected to the adaptive heat dissipation column 9, and the other end of the elastic threaded strip 12 is connected to the inner wall of the limiting shell 11. The function of the elastic threaded strip 12 is to provide a pre-tightening force to maintain close contact between the adaptive heat dissipation column 9 and the heat conduction cavity, thereby improving the heat conduction efficiency. In addition, when the adaptive heat dissipation column 9 is displaced by an external force, the elastic threaded strip 12 can reset it, so that the adaptive heat dissipation column 9 can be quickly reset when the external force is removed. Example

[0044] like Figure 7As shown, a cylindrical cavity 13 is provided inside the elastic threaded strip 12. A plurality of coaxially connected heat-conducting rings 14 are evenly arranged on the inner surface of the inner circle of the elastic threaded strip 12. The heat-conducting rings 14 are made of graphene. Utilizing the excellent heat-conducting performance of graphene, it serves as the main heat-conducting medium. The annular design facilitates the formation of a continuous heat-conducting path during extrusion. When the elastic threaded strip 12 is in an extruded state, the heat-conducting rings 14 will concentrate and axially contact. Extruding the threaded strip will force the internal heat-conducting rings 14 to contact each other. Since the graphene rings are coaxially arranged, during extrusion, the heat-conducting rings 14 will be tightly stacked along the axis to form a dense graphene heat-conducting layer. After the pressure is released, when the extrusion is removed and the elastic threaded strip 12 returns to its original state, the contact between the heat-conducting rings 14 disappears and they disperse from each other. This dispersed state can reduce the overall heat-conducting coefficient, especially in the axial direction.

[0045] As Figure 7 shown, a heat-insulating film 15 with a mesh structure is arranged on the outer surface of the elastic threaded strip 12. The heat-insulating film 15 is made of aluminum foil. Aluminum foil has a high reflectivity, especially with a very good reflection effect on infrared rays (thermal radiation). Aluminum foil mainly blocks heat transfer by reflecting thermal radiation. It can reflect most of the incident thermal radiation back, thereby reducing the heat entering or dissipating. The mesh structure reduces the direct contact area between the aluminum foil and the threaded strip; reducing heat conduction. And the mesh structure enables the aluminum foil to bend and deform to a certain extent, better adapting to the elastic deformation of the threaded strip and preventing the aluminum foil from tearing when the threaded strip is stretched or compressed.

[0046] As Figure 7 shown, heat-conducting fibers 16 are evenly distributed at the end of the adapted heat-dissipating column 9. The heat-conducting fibers 16 are located in the internal cavity 13 of the elastic threaded strip 12. The heat-conducting fibers 16 are made of a material with high heat-conducting performance, specifically beryllium copper alloy. By evenly distributing the heat-conducting fibers 16 at the end of the adapted heat-dissipating column 9 and extending them into the internal cavity 13 of the elastic threaded strip 12, the contact area between the heat-dissipating column and the threaded strip can be significantly increased. More contact area means more heat can be transferred from the heat-dissipating column to the heat-conducting fibers 16 and then from the heat-conducting fibers 16 to other parts of the threaded strip. Embodiment

[0047] As Figure 8 shown, a cooling component 17 is provided inside the limiting housing 11. The cooling component 17 includes a cooling cavity provided inside the limiting housing 11. The cooling cavity is communicated with the internal cavity 13 of the elastic threaded strip 12. A coolant input end and a heat exchange output end are provided on the limiting housing 11. Among them, the coolant input end is used to inject coolant into the inside of the cooling cavity and output the heat-exchanged liquid through the heat exchange output end for circulation.

[0048] AsFigure 8 As shown, the limit housing 11, as the carrier of the cooling component 17, needs to have a certain strength and sealing performance; the coolant flows in the cooling cavity, exchanges heat with components such as the limit housing 11 and the clamping block 303, and absorbs heat. And the cooling cavity is communicated with the internal cavity 13 of the elastic threaded strip 12, which can make full use of the surface area of the elastic threaded strip 12 for heat exchange and improve the heat dissipation efficiency. The coolant can directly flow through the elastic threaded strip 12 to take away heat.

[0049] As Figure 8 shown, further, the coolant input end of the limit housing 11 is connected to a coolant pump for injecting coolant into the cooling cavity. And the heat exchange output end is connected to an external radiator, so as to discharge the coolant after absorbing heat and form a cycle.

[0050] As Figure 8 and Figure 9 shown, the coolant input end of the limit housing 11 is connected to the coolant pump through a coolant input pipe 18. A pressurizing component 19 is provided on the coolant input pipe 18. The pressurizing component 19 includes a pressurizing housing 1905. A driving motor is fixedly installed on the outer surface of the pressurizing housing 1905. The output end of the driving motor is connected to a first gear 1901. A second gear 1902 is meshed and connected to one side of the first gear 1901. And rotating shafts 1903 are fixedly installed on the central axes of the first gear 1901 and the second gear 1902. The rotating shafts 1903 penetrate through the inside of the pressurizing housing 1905 and are connected to pressurizing guide vanes 1904. The pressurizing guide vanes 1904 are of an S-shaped structure.

[0051] As Figure 8 and Figure 9 shown, the driving motor provides power to drive the first gear 1901 to rotate. The first gear 1901 drives the second gear 1902 and the rotating shafts 1903 to rotate, so that the pressurizing guide vanes 1904 rotate. When the pressurizing guide vanes 1904 rotate, the S-shaped structure will push the coolant, increasing the flow rate and pressure of the coolant. So that the coolant can circulate faster and take away heat more effectively.

[0052] A method for measuring the wind resistance torque of the static disk 6, based on the above-mentioned measuring device for the wind resistance torque of the static disk 6, its measuring steps include: S1: Place the static disk 6 between two sliders 302, and adjust the distance between the sliders 302 so that the card slot 304 in the clamping block 303 contacts the surface of the static disk 6, and fix the position of the slider 302 through bolts, so as to clamp the static disk 6 in a surrounding manner inside the clamping block 303.

[0053] S2: Connect the coolant input end of the limit housing 11 to a coolant pump to inject coolant into the cooling chamber; and connect the heat exchange output end to an external radiator to discharge the coolant after absorbing heat, thus forming a cycle for cooling the static disk 6.

[0054] S3: Provide power with the help of a driving motor to drive the first gear 1901 to rotate; the first gear 1901 drives the second gear 1902 and the rotating shaft 1903 to rotate, so that the pressurizing and guiding vane 1904. When the pressurizing and guiding vane 1904 rotates, the S-shaped structure will push the coolant to further increase the flow rate and pressure of the coolant.

[0055] S4: During the detection process, the driving motor 2 serves as a power source to drive the rotor 5 to rotate; the rotation speed and direction of the rotor 5 are controllable; when the rotor 5 rotates, it will generate air flow, and then generate an air resistance torque acting on the static disk 6; this torque is transmitted to the static torque measuring instrument 4 through the static disk 6. The static torque measuring instrument 4 accurately measures the torque value received by the static disk 6 and transmits the data to the controller; the controller receives the data from the static torque measuring instrument 4, processes, displays and obtains the torque-related data of the static disk 6.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present application shall be covered within the protection scope of the present application.
