Description

Technical Field

[0001] This invention belongs to the field of machining and relates to a rotor blade axial positioning retainer assembly device and method. Background Technology

[0002] In the complex mechanical system of aero-engines, the low-pressure compressor, as a key component, directly affects the overall operating efficiency and safety of the engine due to its stability and reliability. The low-pressure compressor rotor blades, as the core element for gas compression, require a rational and stable mounting structure. Currently, aero-engine low-pressure compressor rotor blades are typically mounted into the mortise and tenon joint of the rotor disc using an axial dovetail tenon structure. This structure, with its unique design advantages, has been widely used in the aviation field. The axial dovetail tenon structure, through specific geometric design, forms a tight and stable connection between the rotor blades and the rotor disc, capable of withstanding the enormous centrifugal and aerodynamic forces generated during engine operation, ensuring stable operation of the rotor blades under high-speed rotation. However, the connection between the tenon and mortise alone is insufficient to fully guarantee the axial stability of the rotor blades. During engine operation, the rotor blades are subjected to complex mechanical forces, including airflow impact and their own inertial forces. These forces can cause axial displacement of the rotor blades, affecting the normal operation of the compressor and even leading to serious safety accidents. Therefore, reliable axial positioning of the rotor blades is essential to prevent back-and-forth movement in the axial direction. In existing technical solutions, axial positioning rings are used to prevent rotor blades from moving axially forward, while the wheel disk mounting edge is used to prevent rotor blades from moving axially backward. This dual protection mechanism ensures the stability of the rotor blades' axial position to a certain extent, providing basic support for the safe operation of aero engines.

[0003] The axial positioning retaining ring, a key component for axial positioning of rotor blades, boasts an ingenious and unique structural design. This ring is annular with an opening at one point, a design that provides it with a degree of elastic deformation, allowing it to adapt to different installation environments during assembly. In its free state, the diameter of the axial positioning retaining ring is slightly larger than the diameter of the disc retaining ring mounting groove. This design ensures sufficient elastic deformation during assembly, resulting in a tight fit with the disc mounting groove and guaranteeing reliable positioning. During assembly, the left retaining ring head is first inserted into the disc groove. Due to the inherent elasticity of the axial positioning retaining ring, it can be deformed by radial bending, reducing its diameter and allowing the entire ring to be assembled into the groove. However, the right retaining ring head is still outside the groove at this point, requiring further manipulation to engage it within the disc's retaining ring groove. This assembly process demands precise control of the deformation degree and assembly position to ensure accurate installation of the axial positioning retaining ring and effective axial positioning of the rotor blades. The entire assembly process requires high operational skills and process precision. Any deviation in any step may affect the assembly quality and, consequently, the axial positioning effect of the rotor blades.

[0004] Currently, the common method used in assembling axial positioning retainers by separating the retainer heads on both sides is to align a nylon rod with one retainer head and then use a hammer to strike it into place. While this method can achieve assembly of the axial positioning retainer to some extent, it has significant drawbacks. Specifically, during the hammering process, the impact force of the hammer acts directly on the head of the axial positioning retainer. Because the structure of the axial positioning retainer head is relatively thin, this direct impact force can easily cause damage to the head, such as scratches, deformation, or even cracks. Statistics show that the probability of damage using the existing assembly method is about 10%, and this high damage rate has many adverse effects on production. From a production cycle perspective, once the head of the axial positioning retainer is damaged during assembly, it needs to be replaced or repaired, which undoubtedly increases the additional assembly time and workload, leading to a longer production cycle and affecting the overall production schedule of the aero-engine. From a product quality perspective, damage to the head of the axial positioning retainer may affect its fitting accuracy with the rotor retainer groove, reduce the reliability of axial positioning, and thus affect the working stability of the rotor blades, posing a potential threat to the safe operation of the aero-engine. Therefore, existing assembly methods urgently need improvement. Summary of the Invention

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0026] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings: See Figures 1 to 4 In one embodiment of the present invention, a rotor blade axial positioning retainer assembly device is provided, specifically a device suitable for assembling axial positioning retainers for rotor blades of low-pressure compressors in aero engines.

[0028] Specifically, the rotor blade axial positioning retainer assembly device of the present invention includes a body 1; a hook block mounting hole is formed on the side wall of the body 1; a hook block 2 is provided in the hook block mounting hole; in use, one end of the hook block 2 protrudes from the hook block mounting hole and is used to hook the retainer head on the side of the axial positioning retainer that is not assembled in place; a guide hole communicating with the hook block mounting hole is provided on the side wall of the hook block mounting hole, and the guide hole has the same curvature as the axial positioning retainer; a guide member 7 is provided in the guide hole, and one end of the guide member 7 passes through the guide hole and connects to the hook block 2; a fixing member 6 is provided on the body 1, and the fixing member 6 is used to connect the wheel to which the axial positioning retainer is to be assembled.

[0029] This invention relates to a rotor blade axial positioning retainer assembly device. By providing hook block mounting holes and hook blocks 2 on the side wall of the main body 1, one end of the hook block 2 extends through the mounting hole and hooks the retainer head on the side that is not properly assembled. This design eliminates the possibility of damage to the retainer head caused by impacts in previous assembly methods. The smooth pushing operation ensures the retainer head remains intact, guaranteeing the axial positioning retainer is assembled in one go. This effectively avoids the quality risks caused by impacting the axial positioning retainer head, providing a reliable guarantee for the stable operation of the rotor blades. Secondly, the rotor blade axial positioning retainer assembly device is easy to install and disassemble. The fixing part 6 on the main body can quickly fix the main body 1 to the wheel, and it can be easily removed after assembly, greatly saving assembly time and improving work efficiency. Furthermore, the ingenious structural design features a guide hole with the same curvature as the axial positioning retainer. The guide part 7 connects to the hook block within the guide hole, ensuring precise and stable movement of the hook block 2 and guaranteeing the accuracy of the assembly process. In addition, the device has a low cost, but can effectively solve the problem of assembling the axial positioning ring of the rotor blade. It can improve the assembly quality while reducing the production cost, and has a very high cost performance and wide application value.

[0030] In one possible implementation, the body 1 is provided with a bolt mounting hole that communicates with the hook block mounting hole; a bolt 4 is provided in the bolt mounting hole and the bolt 4 is threadedly connected to the bolt mounting hole; in use, one end of the bolt 4 passes through the bolt mounting hole and contacts the surface of the hook block 2.

[0031] Explained, a bolt mounting hole communicating with the hook block mounting hole is provided on the main body 1, and a threaded bolt 4 is installed. By rotating the bolt 4, the hook block 2 can be precisely pushed to move circumferentially. Compared with other driving methods, this operation is more precise and controllable, ensuring that the hook block 2 accurately pushes the retaining ring head to the designated position. Then, the elasticity of the axial positioning retaining ring causes the retaining ring head to spring back into the mounting groove, achieving proper assembly. The entire process avoids direct and forceful impact on the retaining ring head, preventing damage, while improving the accuracy and success rate of assembly, effectively ensuring assembly quality and increasing assembly efficiency.

[0032] In one possible implementation, a bushing 5 is provided inside the bolt mounting hole; a set screw 8 is provided on the bushing 5; one end of the set screw 8 passes through the bushing 5 and is connected to the inner wall of the bolt mounting hole; the bolt 4 is threadedly connected to the bushing 5.

[0033] Explain the significant benefits of the design featuring bushing 5 and set screw 8. Bushing 5 is positioned within the bolt mounting hole, and bolt 4 is threadedly connected to bushing 5. This reduces direct friction between bolt 4 and body 1, lowering wear, extending their service life, and improving the device's durability. One end of set screw 8 passes through bushing 5 and connects to the inner wall of the bolt mounting hole, effectively fixing the bushing 5 in place, preventing loosening and ensuring the stability of bolt 4 installation. This combined structure enhances the overall connection reliability of the device, making the operation of bolt 4 pushing hook block 2 more precise and stable, thereby ensuring smooth assembly of the axial positioning ring and improving assembly quality and efficiency.

[0034] In one possible implementation, the fastener 6 is a connecting bolt, which is used to connect to the bolt connection hole on the wheel boss of the wheel to be assembled with the axial positioning ring.

[0035] Explained, the connecting bolts are common and universal standard parts, low in cost and readily available, effectively controlling device costs. Their installation and disassembly are simple and convenient; connection or separation with the wheel disc boss can be quickly achieved simply by rotation, significantly shortening the installation and disassembly time of the assembly device and improving assembly efficiency. Moreover, this connection method is robust and reliable, ensuring that the body 1 is tightly fixed to the wheel disc during assembly, guaranteeing the accuracy and stability of the assembly operation, thereby improving the assembly quality of the axial positioning ring.

[0036] For example, the connecting bolts are hexagon socket head cap bolts. During installation, simply tighten the hexagon socket head cap bolts into the bolt connection holes on the wheel disc boss to complete the installation. The installation time is approximately 1 minute.

[0037] Optionally, two fasteners 6 are provided, located at both ends of the main body 1 respectively.

[0038] Explain that the design of having two fasteners 6, located at opposite ends of the main body 1, offers significant advantages. The two fasteners 6 form a more robust connection structure, ensuring a more balanced and reliable connection between the main body 1 and the wheel bearing the axial positioning ring to be assembled. This effectively prevents wobbling or misalignment that may occur with single-point fixing, guaranteeing the stability of the device during assembly. Simultaneously, the two-end fixing method distributes stress, reducing localized stress concentration and lowering the risk of damage to the wheel bearing and main body 1, thus extending the device's service life. Furthermore, this layout does not interfere with the operation of other components, facilitating a smooth overall assembly process and improving assembly efficiency and quality.

[0039] In one possible implementation, a handle 3 is provided on the hook block 2; an anti-slip layer is provided on the end of the handle 3.

[0040] Explained, a handle 3 is provided on the hook block 2, with an anti-slip layer at the end of the handle 3. The handle 3 provides the operator with a convenient point of force application. When pushing the hook block 2 to assemble the retaining ring head, the operator can apply force more easily, making the operation more effortless and convenient, effectively improving assembly efficiency. The anti-slip layer at the end of the handle 3 increases the friction between the hand and the handle, ensuring a firm grip even when hands are sweaty or oily, preventing slippage and guaranteeing the accuracy and stability of the operation. This further improves the quality and safety of the entire axial positioning retaining ring assembly process.

[0041] In one possible implementation, the hook block mounting hole is a through hole, and the hook block 2 has a handle mounting hole; a handle 3 is provided in the handle mounting hole, and both ends of the handle 3 are located outside the handle mounting hole; an anti-slip layer is provided on the end of the handle 3.

[0042] Explained, the hook block mounting hole is designed as a through hole, and the hook block 2 has a handle mounting hole for mounting the handle 3. This structure makes the connection between the handle 3 and the hook block 2 more stable and compact, reducing the possibility of the handle 3 shaking or loosening during assembly, and improving the stability and accuracy of operation. Both ends of the handle 3 are located outside the handle mounting hole, allowing the operator to hold the handle 3 from different directions, making operation more flexible and adaptable to different assembly postures and spatial environments. This ensures that the snap ring assembly operation can be completed safely and reliably under various working conditions, comprehensively improving the quality and efficiency of assembly.

[0043] In one possible implementation, the end of the guide member 7 away from the hook block 2 is located outside the guide hole, and the diameter of that end of the guide member 7 is greater than the width of the guide hole.

[0044] Explaining this, on the one hand, the end is located outside the guide hole, providing operators with intuitive visual and tactile markings, facilitating quick positioning and adjustment of the guide component 7, and improving assembly efficiency. On the other hand, the end diameter is larger than the guide hole width, forming an effective limiting structure to prevent the guide component 7 from dislodging from the guide hole due to force or vibration during device use, ensuring that the guide component 7 is always stably in the correct position, guaranteeing that the hook block 2 moves smoothly and accurately under the guidance of the guide hole, thereby improving the reliability and assembly quality of the entire axial positioning ring assembly device.

[0045] In one possible implementation, both the body 1 and the hook block 2 are made of MC nylon material.

[0046] Explanatoryly, both the body 1 and the hook block 2 are made of MC nylon material, which is lightweight yet meets structural strength requirements, and ensures that there are no risks of bumps, scratches, or titanium alloy contamination during assembly.

[0047] In another embodiment of the present invention, a method for assembling rotor blade axial positioning retainers is provided, which is based on the above-mentioned rotor blade axial positioning retainer assembly device.

[0048] Specifically, the rotor blade axial positioning ring assembly method of the present invention includes the following steps: Assemble the retaining head on one side of the axial positioning retaining ring into the retaining ring mounting groove of the wheel; fix the body 1 on the wheel using the fixing member 6, and hook one end of the hook block 2 to the retaining head on the side where the axial positioning retaining ring is not assembled; by pushing the hook block 2, drive the retaining head on the side where the axial positioning retaining ring is not assembled into the retaining ring mounting groove of the wheel; remove the body 1 from the wheel.

[0049] This invention discloses a method for assembling axial positioning retaining rings for rotor blades. First, the retaining ring head on one side of the axial positioning retaining ring is assembled into the retaining ring mounting groove on the wheel disc. Then, the main body 1 is fixed to the wheel disc using a fixing component 6. A hook block 2 is used to hook the retaining ring head on the side that is not properly assembled. By pushing the hook block 2, the retaining ring head is assembled into place. Finally, the main body 1 is removed. The entire operation process replaces the hammering of the retaining ring head with a smooth pushing method. This innovative operation mode effectively protects the parts, avoids damage caused by hammering, and greatly improves the service life and reliability of the parts. At the same time, this method ensures that the axial positioning retaining ring is assembled in one go, reducing the number of repeated assembly and adjustments, significantly improving work efficiency, and reducing time and labor costs. Furthermore, this method is based on a cleverly designed assembly device with a reasonable structural design and simple, easy-to-understand operation. Workers can master it after simple training, reducing the operational difficulty and technical threshold. This method effectively solves the problem of assembling axial positioning retaining rings for rotor blades, improves assembly quality, and avoids the quality risks caused by hammering the retaining ring head in existing assembly methods.
