[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] like Figure 1-5 As shown, a dynamic balancing-free assembled blade includes a fixing member 1,
[0028] The shaft sleeve 4 is centrally symmetrically mounted on the outside of the fixing member 1, and the shaft sleeve 4 is detachably connected to the fixing member 1;
[0029] The wheel hub 3 is detachably connected to the shaft sleeve 4;
[0030] A buckle cover 2, which is installed inside the wheel hub 3;
[0031] Blade 5, a petiole 51 is provided at one end of blade 5, petiole 51 is detachably connected to buckle cover 2, and a blade wing 53 is provided at the other end of blade 5; fixing part 1 is used as the basic supporting part of the whole assembled blade, and is used to fix and support other components. Fixing part 1 needs to have sufficient strength and stability to ensure that blade 5 will not be displaced or deformed under high-speed rotation or other working conditions; sleeve 4 is a key component connecting fixing part 1 and hub 3, which allows hub 3 to rotate on fixing part 1; the central symmetric design helps to reduce vibration and unbalanced force caused by rotation, thereby improving the stability and performance of blade 5; the detachable connection between sleeve 4 and fixing part 1 makes the assembly and disassembly of blade 5 simple and convenient, and is easy to repair and replace; hub 3 is the main support of blade 5 The hub 3 is a part used to connect the sleeve 4 and the blade 5; the detachable connection between the hub 3 and the sleeve 4 allows the blade 5 to be easily separated when it is necessary to replace or repair them, thereby improving maintenance efficiency; the buckle cover 2 is installed inside the hub 3 to fix the petiole 51 of the blade 5 to ensure that the blade 5 does not fall off or shift during rotation; the buckle cover 2 needs to have sufficient strength and sealing to prevent leakage or falling off under high-speed rotation or other working conditions; the blade 5 is the core part of the blade 5 system, which is used to generate thrust or convert energy; the detachable connection between the petiole 51 and the buckle cover 2 allows the blade 5 to be replaced or repaired without removing the entire hub 3, further improving maintenance efficiency; the blade wing 53 is the working part of the blade 5, and its shape and size directly affect the performance of the blade 5. The design of the blade wing 53 needs to consider the principles of fluid dynamics to achieve optimal performance and efficiency; through this design, the dynamic unbalanced assembly blade without dynamic balance can greatly reduce the dynamic unbalance problem caused by improper assembly or material inhomogeneity. At the same time, the design of modular components makes the assembly, disassembly and maintenance of the blade 5 simple and convenient, improving work efficiency and reliability. In addition, the centrally symmetrical design of the sleeve 4 and the detachably connected components also increase the stability and durability of the blade 5 .
[0032] like Figure 5 As shown, a circle of breaking pieces 52 is provided inside the petiole 51; when the blade 5 is subjected to excessive external impact or abnormal vibration, the breaking piece 52 can break in a preset manner to prevent the blade 5 from being further damaged, or even to prevent the entire device from causing a more serious failure due to damage to the blade 5. This design can protect the device from damage to a certain extent and reduce maintenance costs; the design of the breaking piece 52 usually takes into account the dynamic balance performance of the blade 5. When the mass distribution of the blade 5 is uneven due to some reasons (such as wear, impact, etc.), the breaking piece 52 can adjust the mass distribution of the blade 5 by breaking, thereby reducing or eliminating the dynamic imbalance phenomenon. This helps to maintain the stable operation of the equipment and extend its service life.
[0033] like Figure 3As shown, the sleeve 4 is installed on the fixing member 1 by the square head screw 6, and the buckle cover 2 and the wheel hub 3 are fixedly connected by bolts and nuts; the design of the square head screw 6 makes the installation and removal of the sleeve 4 relatively easy. When it is necessary to adjust the position of the shaft or replace the sleeve 4, it can be achieved by removing the square head screw 6. This design facilitates the maintenance and servicing of the equipment; another advantage of the bolt and nut connection is that it is easy to adjust and repair. When it is necessary to adjust the position of the buckle cover 2 or replace the buckle cover 2, it can be achieved by removing the bolts and nuts. This design makes the maintenance and servicing of the equipment easier and more convenient.
[0034] In this embodiment, the blade 5 is made of a plastic composite material of nylon and glass fiber; the blade 5 module is made of a composite material of nylon and glass fiber. The composite material of nylon and glass fiber is uniform in quality, light in weight and high in strength, ensuring that the mass of the blade 5 itself is evenly distributed and reducing the generation of imbalance.
[0035] In this embodiment, the thickness of the blade 5 gradually transitions from thick to thin; the thickness of the blade 5 is controlled to improve the structural strength and rigidity and reduce the internal cavity problem caused by uneven thickness.
[0036] In this embodiment, the buckle cover 2, the shaft sleeve 4, the hub 3 and the blade 5 are all made by precision machining through an injection mold; the buckle cover 2, the shaft sleeve 4, the hub 3 and the blade 5 and other parts are made by precision machining through an injection mold to ensure that the surface of the blade 5 produced by the mold is smooth and flat, thereby avoiding the influence of surface imbalance on the overall balance of the blade 5.
[0037] In this embodiment, a circle of toothed buckles 54 are provided on the petiole 51, and the petiole 51 is clipped on the buckle cover 2; the clip connection mode makes the installation and removal of the petiole 51 simple and convenient. When the blade 5 needs to be replaced or repaired, the petiole 51 and the buckle cover 2 can be easily separated by simply unfastening the clip part, thereby improving the maintenance efficiency of the equipment.
[0038] In summary, the non-dynamic balancing assembled blade is designed and manufactured separately for the fixing part 1, the shaft sleeve 4, the wheel hub 3, the buckle cover 2, the blade 5 and other parts, and finally the various parts are assembled. During the assembly, the various parts are combined together through standardized interfaces and connection methods to form a complete blade 5. The shaft sleeve 4 is centrally symmetrically installed on the outside of the fixing part 1, the shaft sleeve 4 is detachably connected to the fixing part 1, the wheel hub 3 is detachably connected to the shaft sleeve 4, the buckle cover 2 is installed inside the wheel hub 3, and a petiole 51 is provided at one end of the blade 5, and the petiole 51 is detachably connected to the buckle cover 2; this design not only improves the maintainability of the blade 5, but also reduces the dynamic damage caused by the quality problem of a single part. Unbalance risk; small residual imbalance can reduce equipment shock and vibration, improve equipment stability and reliability, and extend equipment service life; small residual imbalance can reduce noise and vibration during equipment operation, improve working environment, and improve operator comfort and safety; good dynamic balance can reduce wear and damage of impellers and mechanical parts, and reduce equipment maintenance and repair costs; small residual imbalance can reduce energy loss during equipment operation, improve production efficiency and output, and reduce energy consumption; the gradual transition of blade 5 thickness improves the structural strength and rigidity of blade 5, and reduces the internal cavity problem caused by uneven thickness of blade 5.
