[0027] 200 blades. Detailed Implementation

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] Combination Figure 1 , Figure 2 and Figure 3According to the nozzle ring 100 of the present invention, the nozzle ring 100 can be used to install blades 200. The nozzle ring 100 includes a disk assembly 10 and a clamping assembly 20. The disk assembly 10 is provided with a receiving groove 11 extending in the radial direction. The clamping assembly 20 is disposed in the receiving groove 11 and includes a first clamping member 21 and a second clamping member 22. The first clamping member 21 is disposed in the receiving groove 11 and is adapted to slide in the radial direction. The second clamping member 22 is disposed in the same receiving groove 11 as the first clamping member 21 and is adapted to slide in the radial direction. A mounting portion 23 is formed between the first clamping member 21 and the second clamping member 22. The mounting portion 23 is used to install blades 200.

[0031] Specifically, the first clamping member 21 and the second clamping member 22 are both disposed in the same receiving groove 11, and the first clamping member 21 and the second clamping member 22 are disposed opposite to each other in the radial direction. A mounting part 23 is formed between the first clamping member 21 and the second clamping member 22, and the blade 200 is mounted on the nozzle ring 100 through the mounting part 23.

[0032] Furthermore, the first clamping member 21 and the second clamping member 22 can slide on the same side in the radial direction within the receiving groove 11, so that the mounting part 23 can slide within the receiving groove 11 to adjust the distance between the mounting part 23 and the central axis of the disk assembly 10, thereby adjusting the mounting position of the blade 200. When multiple blades 200 need to be set on the nozzle ring 100, the diameter of the circle formed by the multiple blades 200 can be adjusted by adjusting the distance between the multiple mounting parts 23 and the central axis of the disk assembly 10, so that the nozzle ring 100 can be adapted to turbines of different sizes.

[0033] Furthermore, the first clamping member 21 and the second clamping member 22 can be radially separated or close to each other within the receiving groove 11, so that the size of the mounting part 23 can be adjusted by adjusting the relative position of the first clamping member 21 and the second clamping member 22, so that the nozzle ring 100 can be adapted to blades 200 of different sizes, further ensuring the adaptability of the nozzle ring 100.

[0034] The nozzle ring 100 needs to be matched with the turbine. Different turbines require different nozzle ring sizes and positions. In related technologies, the nozzle ring cannot be adjusted accordingly, which means that the nozzle ring needs to be redesigned when it is matched with different turbines. This makes the design and production process of the nozzle ring complicated and inconvenient for the processing and production of the nozzle ring.

[0035] This application provides a receiving groove 11 within the disk assembly 10, allowing the first clamping member 21 and the second clamping member 22 to slide within the receiving groove 11, thereby adjusting the position of the mounting part 23. This allows the mounting position of the blade 200 to be adjusted, enabling the nozzle ring 100 to be adapted to turbines of different sizes. Furthermore, the size of the mounting part 23 can be adjusted by regulating the relative positions of the first clamping member 21 and the second clamping member 22 within the receiving groove 11, further ensuring the adaptability of the nozzle ring 100 to blades 200 of different sizes.

[0036] According to the nozzle ring 100 of the present invention, by providing a receiving groove 11 in the disk assembly 10 and allowing the first clamping member 21 and the second clamping member 22 to slide in the receiving groove 11, the position of the mounting part 23 is adjusted, thereby adjusting the mounting position of the blade 200 to adapt to different turbines. By adjusting the relative position of the first clamping member 21 and the second clamping member 22 in the receiving groove 11 to adjust the size of the mounting part 23, the nozzle ring 100 can adapt to blades 200 of different sizes. The adaptability of the nozzle ring 100 can be guaranteed without redesigning the nozzle ring 100, while reducing the design and manufacturing difficulty of the nozzle ring 100 and facilitating the processing and production of the nozzle ring 100.

[0037] In some embodiments of the present invention, the blade 200 includes a mounting shaft and a blade body. The mounting shaft is arranged perpendicular to the blade body. The mounting part 23 is used to assemble the mounting shaft so that the blade 200 can be mounted on the disc assembly 10. The blade body is welded to the fork of the turbocharger to prevent the blade 200 from falling off the nozzle ring 100.

[0038] Combination Figure 1 and Figure 2 In some embodiments of the present invention, the disk assembly 10 includes a support disk 12 and a limiting disk 13. The support disk 12 is provided with a first groove 121 extending in the radial direction, and the limiting disk 13 is provided with a second groove 131 extending in the radial direction. There are two limiting disks 13, which are respectively provided on both sides of the support disk 12 in the axial direction. The second groove 131 and the first groove 121 together form a receiving groove 11.

[0039] Specifically, the support plate 12 and the limiting plate 13 are arranged opposite to each other in the axial direction, and the support plate 12 is sandwiched between the two limiting plates 13. The limiting plate 13 and the support plate 12 can be connected by welding to ensure the reliability of the connection between the limiting plate 13 and the support plate 12.

[0040] Furthermore, the first clamping member 21 and the second clamping member 22 are disposed in the first groove 121, and the widths of the first clamping member 21 and the second clamping member 22 can be the same. The width of the first groove 121 is greater than the width of the first clamping member 21 or the width of the first groove 121 is exactly matched with the width of the first clamping member 21, so that the first clamping member 21 and the second clamping member 22 can slide in the radial direction in the first groove 121. At the same time, the first groove 121 can guide the movement direction of the clamping assembly 20.

[0041] The thickness of the first clamping member 21 and the second clamping member 22 can be the same. The first clamping member 21 and the second clamping member 22 are provided to protrude from the support plate 12 in the axial direction. The second groove 131 is provided opposite to the first groove 121 in the axial direction, and the width of the second groove 131 is smaller than the width of the first clamping member 21. After adjusting the position of the first clamping member 21 and the second clamping member 22 in the first groove 121 to complete the adjustment of the size or position of the mounting part 23, the two limiting plates 13 are welded to both sides of the support plate 12 respectively. The two limiting plates 13 can clamp the first clamping member 21 and the second clamping member 22 to limit the first clamping member 21 and the second clamping member 22 in the radial, axial and circumferential directions, improve the stability of the first clamping member 21 and the second clamping member 22, improve the stability of the mounting part 23, thereby improving the stability of the blade 200 and preventing the blade 200 from shaking. It is understandable that the width of the second groove 131 is greater than or equal to the size of the mounting part 23, so as to facilitate the installation of the blade 200 and prevent the limiting plate 13 from interfering with the assembly of the blade 200.

[0042] It should be noted that "thickness" refers to the axial dimension of the component within the nozzle ring 100.

[0043] like Figure 1 As shown, in some embodiments of the present invention, the support disk 12 is provided with a first hollow portion 122 in the middle, the radial inner end of the first groove 121 is open and communicates with the first hollow portion 122; the disk assembly 10 also includes an inner disk 14, which is disposed in the first hollow portion 122 and is connected to the support disk 12, and is adapted to close the radial inner end of the first groove 121.

[0044] Specifically, the first hollow portion 122 can be constructed as a circular hole, and one end of the first groove 121 near the central axis of the support plate 12 is connected to the first hollow portion 122. The inner plate 14 is disposed in the first hollow portion 122, and the inner plate 14 can be connected to the peripheral wall of the first hollow portion 122 by welding, thereby realizing the fixed connection between the inner plate 14 and the support plate 12.

[0045] Furthermore, the inner plate 14 and the first groove 121 are arranged opposite each other in the radial direction, and the inner plate 14 is fixedly connected to the radial inner end of the first groove 121. Thus, the inner plate 14 can close the radial inner end of the first groove 121, and the radial inner end of the clamping assembly 20 can be connected to the inner plate 14, which facilitates the connection of the clamping assembly 20 and prevents the clamping assembly 20 from falling off.

[0046] The inner disk 14 can be selected according to different sizes of turbines. By replacing different inner disks 14, the nozzle ring 100 can be matched with turbines of different sizes without redesigning the overall structure of the nozzle ring 100, thus reducing the design and production difficulty of the nozzle ring 100.

[0047] Optionally, the middle position of the support plate 12 can also be formed with an installation structure that has the same function as the inner plate 14. By replacing different support plates 12, the nozzle ring 100 can be matched with turbines of different sizes. At the same time, this setting can simplify the structure of the nozzle ring 100 and facilitate the machining and assembly of the nozzle ring 100.

[0048] In some embodiments of the present invention, the limiting disk 13 is provided with a second hollow portion, which is disposed opposite to the first hollow portion 122, and the inner disk 14 is disposed opposite to the non-hollowed-out area of ​​the limiting disk 13.

[0049] Specifically, the second hollow part can be constructed as a circular hole structure, and the first hollow part 122 and the second hollow part can be coaxial and arranged opposite to each other. The diameter of the second hollow part is smaller than the diameter of the first hollow part 122. When the inner plate 14 and the support plate 12 are assembled and the limiting plate 13 and the support plate 12 are assembled, at least a portion of the radially outer side of the second hollow part is arranged opposite to the inner plate 14 in the axial direction. The non-hollowed-out areas on the two limiting plates 13 can clamp the inner plate 14 in the axial direction. The inner plate 14 can be welded to the non-hollowed-out part on the limiting plate 13 that is arranged opposite to it. The connection method between the inner plate 14 and the limiting plate 13 can be determined by the specific working conditions and is not limited here.

[0050] Combination Figure 1 and Figure 2 In some embodiments of the present invention, the support disk 12 is provided with a protrusion 123, which protrudes axially from the surface of the support disk 12 opposite to the limiting disk 13, and at least a portion of the protrusion 123 is disposed in the second groove 131.

[0051] Specifically, the protrusion 123 is disposed at the radial outer end of the first groove 121, and the protrusion 123 and the inner disk 14 are disposed opposite each other in the radial direction. The end of the clamping assembly 20 away from the inner disk 14 can be connected to the protrusion 123. The inner ring and the protrusion 123 together define the size of the first groove 121 in the radial direction, thereby limiting the range of movement of the clamping assembly 20. The protrusion 123 can close the radial outer side of the first groove 121 to prevent the clamping assembly 20 from falling off the support disk 12.

[0052] Furthermore, when the limiting plate 13 is assembled, the protrusion 123 can be engaged in the second groove 131 to facilitate the positioning and installation of the limiting plate 13 and the support plate 12, prevent the first groove 121 and the second groove 131 from being misaligned, and improve the assembly convenience of the limiting plate 13 and the support plate 12.

[0053] Optionally, the axial dimension of the protrusion 123 can be the same as or smaller than that of the second groove 131. When the limiting plate 13 and the support plate 12 are positioned and engaged, the entire protrusion 123 is disposed within the second groove 131. Alternatively, the axial dimension of the protrusion 123 can be larger than that of the second groove 131. When the limiting plate 13 and the support plate 12 are positioned and engaged, a portion of the protrusion 123 is disposed within the second groove 131. The specific dimensions of the protrusion 123 are not limited here, as long as it can be positioned and engaged with the second groove 131.

[0054] In some embodiments of the present invention, the radially outer end of the second groove 131 is open, and the protrusion 123 is disposed in the second groove 131 and is adapted to close the open end of the second groove 131.

[0055] Specifically, the first groove 121 and the second groove 131 have the same dimensions in the radial direction. The protrusion 123 is disposed at the radial outer end of the first groove 121, so that the protrusion 123 is disposed opposite to the radial outer end of the second groove 131. The radial outer end of the second groove 131 is open to facilitate positioning and engagement with the protrusion 123. After the limiting plate 13 and the support plate 12 are positioned, the protrusion 123 is engaged in the second groove 131 to seal the radial outer end of the second groove 131.

[0056] like Figure 1 As shown, in some embodiments of the present invention, there are multiple receiving slots 11, which are evenly spaced in the circumferential direction of the disk assembly 10. The clamping components 20 are constructed in multiple sets, and the multiple sets of clamping components 20 are arranged in a one-to-one correspondence with the multiple receiving slots 11.

[0057] Specifically, each receiving slot 11 may be provided with a set of clamping components 20, and each set of clamping components 20 has a mounting part 23 formed thereon. Multiple sets of clamping components 20 are evenly spaced along the circumferential direction on the disk assembly 10, so that multiple mounting parts 23 are evenly spaced along the axial direction on the disk assembly 10, so that multiple blades 200 can be evenly mounted on the disk assembly 10.

[0058] Furthermore, the multiple blades 200 form a circle around the central axis of the disk assembly 10. The diameter of the circle formed by the multiple blades 200 adapted to different turbines is different. By manually driving multiple sets of clamping assemblies 20 to slide radially in the receiving groove 11, the distance between multiple mounting parts 23 relative to the central axis of the disk assembly 10 can be adjusted, thereby adjusting the diameter of the circle formed by the multiple blades 200. This allows the nozzle ring 100 to be adapted to different turbines without the need to redesign the size of the nozzle ring 100, thus improving the adaptability of the nozzle ring 100.

[0059] Combination Figure 1 and Figure 2 In some embodiments of the present invention, the clamping assembly 20 includes: a first elastic drive member 24 and a second elastic drive member 25. The first elastic drive member 24 is connected between the side wall of the receiving groove 11 and the first clamping member 21, and the first elastic drive member 24 is in an energy storage state and is adapted to drive the first clamping member 21 to move towards the second clamping member 22. The second elastic drive member 25 is connected between the side wall of the receiving groove 11 and the second clamping member 22, and the second elastic drive member 25 is in an energy storage state and is adapted to drive the second clamping member 22 to move towards the first clamping member 21.

[0060] Specifically, the first clamping member 21 and the second clamping member 22 are both disposed in the first groove 121. The first clamping member 21 can be disposed close to the protrusion 123, and the second clamping member 22 can be disposed close to the inner disk 14. The first elastic driving member 24 is connected to the first clamping member 21 and the protrusion 123 respectively, and the second elastic driving member 25 is connected to the inner disk 14 and the second clamping member 22 respectively.

[0061] Furthermore, the first clamping member 21 can deform the first elastic driving member 24, thereby allowing the first elastic driving member 24 to store energy. The second clamping member 22 can deform the second elastic driving member 25, thereby allowing the second elastic driving member 25 to store energy. When it is necessary to increase the diameter of the circle formed by the multiple blades 200, the first clamping member 21 can be manually driven to move away from the central axis of the disk assembly 10. At the same time, the second elastic driving member 25 releases energy to drive the second clamping member 22 to move closer to the first clamping member 21, thereby causing the mounting part 23 to move away from the central axis of the disk assembly 10, thereby increasing the distance between the blades 200 and the central axis of the disk assembly 10, and thus increasing the diameter of the circle formed by the multiple blades 200.

[0062] Accordingly, the distance between the mounting part 23 and the central axis of the disk assembly 10 can be reduced by moving the clamping assembly 20 towards the central axis of the disk assembly 10, thereby adjusting the mounting position of the blades 200 and reducing the diameter of the circle formed by the multiple blades 200. The deformation trends (i.e., stretching and compression states) of the first elastic drive member 24 and the second elastic drive member 25 are opposite to the above deformation trends, and will not be described in detail here.

[0063] In addition, the size of the mounting part 23 can be adjusted by driving the first clamping member 21 and the second clamping member 22 to move away from or closer to each other in the first groove 121, so that the mounting part 23 can be adapted to blades 200 of different sizes, further improving the adaptability of the nozzle ring 100.

[0064] The first elastic drive member 24 and the second elastic drive member 25 can both be constructed as springs or bellows or other components that can be extended or compressed. The specific construction is not limited here.

[0065] Combination Figure 1 and Figure 2 In some embodiments of the present invention, the first clamping member 21 is provided with a first mounting groove 211 at one end near the second clamping member 22, and the second clamping member 22 is provided with a second mounting groove 221 at one end near the first clamping member 21. The opening of the first mounting groove 211 is opposite to the opening of the second mounting groove 221, and the first mounting groove 211 and the second mounting groove 221 together form the mounting portion 23.

[0066] Specifically, the first clamping member 21 is provided with a first mounting groove 211 at one end near the second clamping member 22. The first mounting groove 211 is constructed as an arc-shaped groove, which is recessed in the radial direction away from the central axis of the disk assembly 10, and the arc-shaped opening of the arc-shaped groove is opposite to the second clamping member 22. The second clamping member 22 is provided with a second mounting groove 221 at one end near the first clamping member 21. The second mounting groove 221 is constructed as an arc, which is recessed in the radial direction towards the central axis of the disk assembly 10, and the opening of the second mounting groove 221 is opposite to the opening of the first mounting groove 211.

[0067] Furthermore, the first mounting groove 211 and the second mounting groove 221 together form the mounting part 23. The mounting part 23 can be constructed as a mounting hole, and the first mounting groove 211 can be engaged with the second mounting groove 221. The mounting shaft of the blade 200 can be inserted into the mounting part 23.

[0068] The radii of the first mounting groove 211 and the second mounting groove 221 can be configured to be the same as the radius of the mounting shaft, or the radius of the first mounting groove 211 and the second mounting groove 221 can be larger than the radius of the mounting shaft, so as to facilitate the assembly of the blade 200.

[0069] Optionally, one of the first clamping member 21 and the second clamping member 22 can be configured as a long spring, and the other of the first clamping member 21 and the second clamping member 22 can be configured as a short spring. Of course, it is understood that the first clamping member 21 and the second clamping member 22 can also be configured as other structures, which are not specifically limited here.

[0070] It should be noted that the above welding connection method can also be replaced by threaded connection or interference fit connection method. The specific connection method can be determined based on the actual working conditions and processing convenience, and is not limited here.

[0071] The turbocharger according to the present invention includes the above-described nozzle ring 100. Depending on the engine operating conditions, the turbocharger uses different turbines, and the nozzle ring 100 needs to be matched with the turbine.

[0072] According to the turbocharger of the present invention, since the turbocharger is provided with the above-mentioned nozzle ring 100, by providing a receiving groove 11 in the disc assembly 10 and allowing the first clamping member 21 and the second clamping member 22 to slide in the receiving groove 11, the position of the mounting part 23 can be adjusted, thereby adjusting the mounting position of the blade 200 to adapt to different turbines. By adjusting the relative position of the first clamping member 21 and the second clamping member 22 in the receiving groove 11 to adjust the size of the mounting part 23, the nozzle ring 100 can be adapted to blades 200 of different sizes without the need to redesign the nozzle ring 100, reducing the production cost of the nozzle ring 100, while the nozzle ring 100 can meet the performance requirements of the turbocharger.

[0073] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
