Description

Technical Field

[0001] The present application belongs to the field of turbine technology, and in particular relates to a turbine assembly that is easy to install. Background Art

[0002] The most common design used in modern engine turbines is a longitudinal, tree-shaped tenon at the blade root. This wedge-shaped tenon is flanked by symmetrically spaced trapezoidal semicircular teeth, typically with four to six pairs of tenons. To prevent axial movement of the turbine blades, some engines employ blade baffles at the front and rear ends of the turbine disc. These baffles are bolted to the disc.

[0003] The patent with publication number CN217669122U discloses an assembly tool for an aircraft engine turbine disk blade, which relates to the field of engine technology, including a turbine disk and a blade. The connecting end of the blade is embedded in a connecting groove opened on the turbine disk, and the connecting groove is not connected to the bottom of the turbine disk, and a clamping block is fixed at one end of the connecting end. A clamping groove adapted to the clamping block is opened in the connecting groove. A connecting ring is fixed between the top of the turbine disk and the connecting end of the turbine disk. A fixing ring is threadedly connected to the outer periphery of the connecting ring, and the fixing ring is tightly attached to the top of the connecting end. The cross-section of the connecting groove is arranged to fit the irregular shape of the connecting end. An annular groove is opened at the top of the turbine disk, and an annular block adapted to the annular groove is fixed to the bottom of the fixing ring.

[0004] The above patent fixes the blades by means of a fixing ring in conjunction with a socket. Although this can achieve a fixing effect, the fixing effect does not provide good protection and is prone to causing damage to the turbine disc and blade retaining ring during the installation process. Utility Model Content

[0005] The purpose of this application is to provide a turbine assembly that is easy to install and can solve the above problems.

[0006] The purpose of this application is to provide a turbine assembly that is easy to install, comprising:

[0007] turbine disc;

[0008] Blades are arranged on the turbine disk, and the blades are provided in plurality and evenly distributed;

[0009] A retaining ring, which is mounted on the turbine disc and is used to compress the blades;

[0010] A mounting assembly, which is arranged on the turbine disc and is used to fix the blades;

[0011] Among them, a mounting flange is provided on the turbine disc, the mounting assembly is connected to the turbine disc through the mounting flange, and the retaining ring is pressed tightly onto the blade.

[0012] The above-mentioned easy-to-install turbine assembly is adopted. By setting up a mounting assembly and connecting it to the turbine disk through a mounting flange, the installation process of the blades is greatly simplified. Compared with the traditional fixing method, this method reduces the installation steps, reduces the installation difficulty, and improves work efficiency. At the same time, the mounting assembly is not only used to fix the blades, but also enhances the fixing effect of the blades by tightening the retaining ring. This double fixing method ensures the stability and reliability of the blades on the turbine disk, and avoids the performance degradation or damage of the turbine assembly caused by loose fixation. And because of the setting of the mounting assembly, it plays a buffering and protective role during the installation process, effectively avoiding the damage to the turbine disk and blade retaining ring that may be caused by improper operation in the traditional fixing method, extending the service life of the turbine assembly and reducing maintenance costs.

[0013] Furthermore, the installation component includes:

[0014] A receiving groove is provided on the turbine disc and cooperates with the retaining ring;

[0015] A pressure ring, which contacts the retaining ring and is used to compress the retaining ring;

[0016] A fixing ring is provided on the pressing ring and connected to the pressing ring, and is used to squeeze the pressing ring and press the retaining ring tightly until the retaining ring is matched with the receiving groove;

[0017] The pressure ring is provided with a mounting hole that matches the mounting flange on the turbine disk, and is fixed to the mounting flange by bolts.

[0018] The setting of the receiving groove forms a precise matching relationship with the retaining ring, ensuring the accurate positioning of the retaining ring when it is finally fixed to the blade, which not only improves the accuracy of installation, but also helps to maintain the overall stability of the turbine assembly. The direct contact between the pressure ring and the retaining ring, and the squeezing effect of the fixing ring on the pressure ring, together constitute a multiple clamping mechanism, ensuring that the blades are firmly fixed on the turbine disk, and can maintain stable performance even under high-speed rotation or extreme working conditions. The mounting holes on the pressure ring that match the mounting flange on the turbine disk, and the method of fixing it to the mounting flange with bolts, make the installation and disassembly of the mounting assembly very simple, which not only improves work efficiency, but also facilitates quick maintenance or replacement when needed.

[0019] At the same time, the overall setting of the installation assembly is compact, and the connection between the various components is tight and reliable, which not only improves the overall strength of the turbine assembly, but also helps to reduce the failure rate caused by loose or damaged components. By introducing the installation assembly composed of receiving grooves, pressure rings, fixing rings and other components, the turbine assembly not only improves the convenience of installation and the stability of fixation, but also enhances the compactness and reliability of the overall structure.

[0020] Further: the pressure ring includes:

[0021] First Ring Body;

[0022] A pressing member is provided on the first ring body, and a contact groove for cooperating with the pressing member is provided on the retaining ring;

[0023] A chute is provided on the first ring body and cooperates with the pressing member, and the pressing member can slide on the chute;

[0024] There are multiple pressing members, and the multiple pressing members are evenly distributed.

[0025] The clamping members are evenly distributed on the first ring body, ensuring that the retaining ring can be evenly stressed when under pressure, avoiding deformation or damage caused by uneven force, which not only improves the clamping effect, but also helps to maintain the overall balance of the turbine assembly. The clamping members can slide on the slide groove, making the clamping process more flexible and controllable. Under the action of the fixing ring, the clamping members gradually move outward, gradually squeezing the retaining ring until it is fixed with the receiving groove. The use of a gradual clamping method helps to reduce the impact and stress during the installation process and improves the accuracy and stability of the installation. At the same time, the cooperation between the clamping members and the receiving groove ensures the precise positioning and limiting of the retaining ring during the installation process, and when the clamping members are fully matched with the receiving groove, they cannot move further, thereby achieving a firm fixation of the blades, which not only improves the accuracy of the installation, but also helps to maintain the overall structural stability of the turbine assembly.

[0026] Furthermore, the connection between the pressure ring and the retaining ring, as well as the sliding mechanism of the compression member on the chute, simplify installation and removal, improving efficiency and facilitating quick maintenance or replacement when necessary. The gradual tightening process and the precise fit of the compression member within the receiving slot effectively minimize potential damage to the turbine disc, blade retaining ring, and blades during installation, extending the life of the turbine assembly and reducing maintenance costs.

[0027] Furthermore, the fixing ring includes:

[0028] Second ring body;

[0029] An extrusion assembly is used to squeeze the pressing member and move it outward, comprising a mounting rod provided on the pressing member, a linkage rod provided on the second ring body, and a positioning rod provided on the second ring body, wherein both ends of the linkage rod are hinged to the mounting rod and the positioning rod respectively;

[0030] A limiting assembly, used to limit the rotation angle of the second ring body relative to the first ring body, comprising an arc-shaped limiting groove provided on the second ring body and a limiting rod provided on the first ring body and cooperating with the arc-shaped limiting groove;

[0031] The fixing ring also includes a fastener for preventing the installation rod, the positioning rod and the linkage rod from being separated.

[0032] The extrusion assembly hinges the mounting rod and the positioning rod via a linkage rod. When the second ring body is subjected to an external force, such as rotation, the linkage rod drives the mounting rod outward, pushing the compression member along the chute, thereby gradually tightening the retaining ring. This not only improves extrusion efficiency but also ensures the stability and controllability of the compression process. The limiter assembly, through the cooperation of the arc-shaped limiter groove and the limiter rod, limits the rotation angle of the second ring body relative to the first ring body, ensuring the distance between the compression member during outward movement and avoiding uneven compression or damage caused by excessive rotation angles. Furthermore, the overall design of the retaining ring is compact, and the connections between the various components are tight and stable. The use of fasteners, which can be nuts, further strengthens the connection strength between the mounting rod, positioning rod, and linkage rod, preventing failures caused by loose components. Despite the relatively complex structure of the retaining ring, the rational design of the connections and coordination between the various components makes installation and maintenance relatively simple, improves work efficiency, and facilitates rapid maintenance or replacement when needed.

[0033] Furthermore, the second ring body is provided with a toggle groove, which is recessed downward.

[0034] The toggle slot allows users to rotate the second ring directly using simple tools or fingers, simplifying installation and removal steps while improving work efficiency. Manual operation using the toggle slot allows users to more precisely control the rotation speed and force of the second ring, thus avoiding unnecessary damage to the turbine disc, blade retaining ring, and blades during installation.

[0035] Furthermore, a limit contact ring is provided on the inner wall of the second ring body and extends downward, and the limit contact ring contacts the inner wall of the first ring body.

[0036] The setting of the limiting contact ring enables the second ring body to maintain stable contact with the inner wall of the first ring body during rotation, prevents the first ring body from separating from the second ring body, and ensures the stability of rotation.

[0037] The beneficial effects of this application are:

[0038] 1. By setting up the mounting assembly and connecting it to the turbine disc through the mounting flange, the installation process of the blade is greatly simplified. Compared with the traditional fixing method, this method reduces the installation steps, reduces the installation difficulty, and improves work efficiency;

[0039] 2. The mounting assembly not only secures the blades but also strengthens the blade fixation by pressing the retaining ring. This dual fixation method ensures the stability and reliability of the blades on the turbine disc and avoids performance degradation or damage to the turbine assembly caused by loose fixation.

[0040] 3. Through the setting of the installation component, it plays a buffering and protective role during the installation process, effectively avoiding the damage to the turbine disc and blade retaining ring caused by improper operation in the traditional fixing method, extending the service life of the turbine component and reducing maintenance costs.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0046] The turbine assembly that is easy to install provided by the embodiment of the present application is described in detail below with reference to specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0047] Example 1:

[0048] like Figure 1 and Figure 2As shown, the embodiment of the present application provides a turbine assembly that is easy to install, including:

[0049] turbine disc 100;

[0050] Blades 110 are provided on the turbine disk 100 , and a plurality of blades 110 are provided and evenly distributed;

[0051] The retaining ring 120 is provided on the turbine disk 100 and is used to press the blades 110;

[0052] A mounting assembly, disposed on the turbine disk 100 and used to fix the blades 110;

[0053] The turbine disk 100 is provided with a mounting flange, and the mounting assembly is connected to the turbine disk 100 via the mounting flange, and the retaining ring 120 is pressed tightly against the blade 110 .

[0054] In some implementations of the embodiments of this application, Figure 1 As shown, the above-mentioned turbine assembly that is easy to install is adopted. By setting up a mounting assembly and connecting it to the turbine disk 100 through a mounting flange, the installation process of the blade 110 is greatly simplified. Compared with the traditional fixing method, this method reduces the installation steps, reduces the installation difficulty, and improves work efficiency. At the same time, the mounting assembly is not only used to fix the blade 110, but also enhances the fixing effect of the blade 110 by pressing the retaining ring 120. This double fixing method ensures the stability and reliability of the blade 110 on the turbine disk 100, and avoids the performance degradation or damage of the turbine assembly caused by loose fixation. And because of the setting of the mounting assembly, it plays a buffering and protective role during the installation process, effectively avoiding the damage to the turbine disk 100 and the blade 110 retaining ring 120 that may be caused by improper operation in the traditional fixing method, extending the service life of the turbine assembly and reducing maintenance costs.

[0055] Example 2:

[0056] An embodiment of the present application provides a turbine assembly that is easy to install. In addition to the above-mentioned technical features, the turbine assembly that is easy to install in an embodiment of the present application also includes the following technical features.

[0057] like Figure 2 As shown, the installation components include:

[0058] The receiving groove 200 is provided on the turbine disk 100 and cooperates with the retaining ring 120;

[0059] The pressure ring 300 contacts the retaining ring 120 and is used to press the retaining ring 120;

[0060] The fixing ring 400 is provided on the pressing ring 300 and connected to the pressing ring 300, and is used to squeeze the pressing ring 300 and make it press the retaining ring 120 tightly until the retaining ring 120 is matched with the receiving groove 200;

[0061] The pressure ring 300 is provided with a mounting hole that matches the mounting flange on the turbine disk 100 and is fixed to the mounting flange by bolts.

[0062] In the embodiment of the present application, the setting of the receiving groove 200 forms a precise matching relationship with the retaining ring 120, ensuring the accurate positioning of the retaining ring 120 when the blade 110 is finally fixed, which not only improves the accuracy of the installation, but also helps to maintain the overall stability of the turbine assembly. The direct contact between the pressure ring 300 and the retaining ring 120, and the squeezing effect of the fixing ring 400 on the pressure ring 300, together constitute a multiple clamping mechanism, ensuring that the blade 110 is firmly fixed on the turbine disk 100, and maintaining stable performance even under high-speed rotation or extreme working conditions. The mounting holes on the pressure ring 300 that match the mounting flange on the turbine disk 100, and the method of fixing it to the mounting flange by bolts, make the installation and disassembly of the mounting assembly very simple, which not only improves work efficiency, but also helps to perform quick maintenance or replacement when needed.

[0063] At the same time, the overall design of the installation assembly is compact, and the connections between the various components are tight and reliable, which not only improves the overall strength of the turbine assembly, but also helps to reduce the failure rate caused by loose or damaged components. By introducing the installation assembly composed of components such as the receiving groove 200, the pressure ring 300, and the fixing ring 400, the turbine assembly not only improves the convenience of installation and the stability of fixation, but also enhances the compactness and reliability of the overall structure.

[0064] Example 3:

[0065] An embodiment of the present application provides a turbine assembly that is easy to install. In addition to the above-mentioned technical features, the turbine assembly that is easy to install in an embodiment of the present application also includes the following technical features.

[0066] like Figure 2 As shown, the pressure ring 300 includes:

[0067] First ring body 310;

[0068] The pressing member 320 is provided on the first ring body 310 , and the retaining ring 120 is provided with a contact groove 330 that cooperates with the pressing member 320 ;

[0069] A sliding groove 340 is provided on the first ring body 310 and cooperates with the pressing member 320. The pressing member 320 can slide on the sliding groove 340.

[0070] There are multiple pressing members 320 , and the multiple pressing members 320 are evenly distributed.

[0071] In this embodiment of the present application, the compression members 320 are evenly distributed on the first ring body 310, ensuring that the retaining ring 120 is evenly stressed when subjected to pressure, avoiding deformation or damage caused by uneven force. This not only improves the compression effect but also helps maintain the overall balance of the turbine assembly. The compression members 320 can slide on the slide grooves 340, making the compression process more flexible and controllable. Under the action of the retaining ring 400, the compression members 320 gradually move outward, gradually squeezing the retaining ring 120 until it engages with the receiving grooves 200 to complete the fixation. This gradual compression method helps reduce impact and stress during installation, improving installation accuracy and stability. Furthermore, the coordination of the compression members 320 with the receiving grooves 200 ensures the precise positioning and limiting of the retaining ring 120 during installation. Once the compression members 320 are fully engaged with the receiving grooves 200, they cannot move further, thereby firmly securing the blades 110. This not only improves installation accuracy but also helps maintain the overall structural stability of the turbine assembly.

[0072] Furthermore, the connection between the pressure ring 300 and the retaining ring 400, as well as the sliding mechanism of the compression member 320 within the chute 340, simplifies installation and removal, improving work efficiency and facilitating rapid maintenance or replacement when necessary. The gradual tightening and precise fit of the compression member 320 within the receiving groove 200 effectively minimize potential damage to the turbine disk 100, blade 110, retaining ring 120, and the blade 110 itself during installation. This extends the life of the turbine assembly and reduces maintenance costs.

[0073] Example 4:

[0074] An embodiment of the present application provides a turbine assembly that is easy to install. In addition to the above-mentioned technical features, the turbine assembly that is easy to install in an embodiment of the present application also includes the following technical features.

[0075] like Figure 2 As shown, the fixing ring 400 includes:

[0076] Second ring body 410;

[0077] The extrusion assembly 420 is used to squeeze the pressing member 320 and move it outward, and includes a mounting rod 421 provided on the pressing member 320, a linkage rod 422 provided on the second ring body 410, and a positioning rod 423 provided on the second ring body 410. The two ends of the linkage rod 422 are hinged to the mounting rod 421 and the positioning rod 423 respectively.

[0078] The limiting assembly 430 is used to limit the rotation angle of the second ring body 410 relative to the first ring body 310, and includes an arc-shaped limiting groove 431 provided on the second ring body 410 and a limiting rod 432 provided on the first ring body 310 and cooperating with the arc-shaped limiting groove 431;

[0079] The fixing ring 400 further includes a fastener for preventing the installation rod 421 , the positioning rod 423 and the linkage rod 422 from being separated.

[0080] In the embodiment of the present application, the extrusion assembly 420 hinges the installation rod 421 and the positioning rod 423 via a linkage rod 422. When the second ring body 410 is subjected to an external force, such as rotation, the linkage rod 422 drives the installation rod 421 to move outward, thereby pushing the pressing member 320 to slide along the slide groove 340, thereby gradually pressing the retaining ring 120. This not only improves the extrusion efficiency but also ensures the stability and controllability of the pressing process. The limiting assembly 430, through the cooperation of the arc-shaped limiting groove 431 and the limiting rod 432, limits the rotation angle of the second ring body 410 relative to the first ring body 310, ensuring the distance of the pressing member 320 during the outward movement and avoiding uneven pressing or damage caused by excessive rotation angle. Furthermore, the overall design of the retaining ring 400 is compact, and the connections between the various components are tight and stable. The use of fasteners further enhances the connection strength between the mounting rod 421, the positioning rod 423, and the linkage rod 422, thereby preventing malfunctions caused by loose components. The fasteners herein may be nuts. Furthermore, despite the relatively complex structure of the retaining ring 400, the connections and coordination between the various components are rationally arranged, making the installation and maintenance process relatively simple, improving work efficiency, and facilitating rapid maintenance or replacement when necessary.

[0081] Furthermore, a toggle groove 500 is provided on the second ring body 410 , and the toggle groove 500 is recessed downward.

[0082] The provision of the toggle slot 500 allows the user to rotate the second ring body 410 directly using a simple tool or finger, simplifying the installation and removal process and improving work efficiency. Furthermore, manual operation through the toggle slot 500 allows the user to more precisely control the rotation speed and force of the second ring body 410, thereby avoiding unnecessary damage to the turbine disk 100, blade 110, retaining ring 120, and blade 110 itself during installation.

[0083] Example 5:

[0084] An embodiment of the present application provides a turbine assembly that is easy to install. In addition to the above-mentioned technical features, the turbine assembly that is easy to install in an embodiment of the present application also includes the following technical features.

[0085] like Figure 2As shown, a limit contact ring 600 is provided on the inner wall of the second ring body 410 and extends downward, and the limit contact ring 600 contacts the inner wall of the first ring body 310 .

[0086] In the embodiment of the present application, the setting of the limiting contact ring 600 enables the second ring body 410 to maintain stable contact with the inner wall of the first ring body 310 during rotation, preventing the first ring body 310 from separating from the second ring body 410 and ensuring the stability of rotation.

[0087] It should be noted that, in this article, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
