Abstract
Description
Technical Field
[0001] This utility model relates to the field of dynamic balancing tooling technology, and in particular to a dynamic balancing tooling for a satellite reaction flywheel rotor. Background Technology
[0002] The satellite reaction flywheel is one of the core components of a satellite attitude control system. Its main working principle is to adjust the satellite's attitude by changing the rotational speed of the flywheel rotor to generate angular momentum, thereby controlling and stabilizing the satellite. However, when the flywheel rotates at high speed, rotor imbalance can cause vibration of the reaction flywheel, leading to mechanical wear and reducing the efficiency of the reaction flywheel system. Therefore, dynamic balancing of the reaction flywheel rotor is crucial.
[0003] Existing dynamic balancing fixtures for reaction flywheel rotors are too heavy and complex, and the disassembly and installation of components are too cumbersome; they lack good adaptability and versatility, and are only designed for specific types or sizes of flywheels; they do not consider the mechanical effects of rotor rotation, resulting in poor stability; and they fail to meet the dust protection requirements of other components besides the rotor.
[0004] In summary, the existing dynamic balancing fixtures for reaction flywheel rotors are complex, have poor adaptability and stability, are only applicable to specific flywheels, and do not take into account the dust protection requirements of other components.
[0005] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Utility Model Content

Figure 2 for Figure 1 A schematic diagram of the dynamic balancing fixture for the reaction flywheel rotor from another perspective. Please refer to... Figure 1 , Figure 2The satellite reaction flywheel rotor dynamic balancing fixture provided in this embodiment includes a base 100, a rotor fixing plate 200, a structural support 300, a splash guard 400, and a rotor motor dust cover 500. The structural support 300 is vertically connected to both the left and right sides of the base 100, and the rotor fixing plate 200 is vertically connected to the top of the base 100. The left and right sides of the rotor fixing plate 200 are respectively connected to the structural support 300. The rotor motor dust cover 500 is connected to the middle of the rotor fixing plate 200, and the splash guard 400 is connected to the rotor fixing plate 200 directly above the rotor motor dust cover 500.
[0031] It should be noted that the base 100 is designed to be relatively wide, providing a stable support surface. The rotor fixing plate 200 is perpendicular to the base 100. A dust cover 500 in the shape of a cover is designed in the central hollow position of the rotor fixing plate 200 to prevent metal chips or dust generated during dynamic balancing and grinding from falling into the motor. At the same time, the anti-splash cover 400 above the rotor fixing plate 200 can block chips and dust from flying upward, thereby ensuring the safety of personnel during the work process. The structural bracket 300 is used to fix the base 100 and the rotor fixing plate 200. It adopts a triangular support structure, and the two sides of the bracket are fixed with bolts to ensure that it can remain stable when subjected to external forces.
[0032] The entire tooling of this utility model is made of aluminum 6061, which has the characteristics of high strength, good corrosion resistance and light weight, ensuring that the reaction flywheel will not deform when running at high speed. Through lightweight and modular design, it is easy to disassemble and assemble, which greatly facilitates field testing, optimizes the workflow and reduces personnel and time costs.
[0033] This utility model's satellite reaction flywheel rotor dynamic balancing fixture solves the problems of complexity, bulkiness, and poor adaptability in existing fixture technologies. Its lightweight and modular structure makes the fixture easy to carry and disassemble, and it is highly adaptable to flywheel rotors of different specifications. At the same time, the design of the splash guard 400 and the rotor motor dust cover 500 improves the cleanliness of the equipment and the safety of personnel. The entire fixture improves efficiency while reducing operating costs.

[0035] Further reference Figure 3 The present invention provides a debris discharge through hole 110 on the base 100 directly below the rotor motor dust cover 500.
[0036] It should be noted that the chip discharge through hole 110 in the middle of the base 100 is a chip discharge channel, which mainly solves the problem of chip accumulation during rotor grinding.
[0037] Further reference Figure 3 The present invention provides waist-shaped holes 120 at the four sides of the base 100.
[0038] It should be noted that the oblong holes 120 at the four corners of the bottom 100 are mounting holes for fixing the dynamic balancing machine to the tooling. A stable assembly is achieved by inserting bolts and tightening nuts or knobs. The oblong holes are designed to facilitate fine-tuning during installation, ensuring that the tooling finds the precise position on the dynamic balancing machine.
[0039] Further reference Figure 3 The present invention provides various specifications of fixing threaded holes 220 on the rotor fixing plate 200.
[0040] It should be noted that the rotor fixing plate 200 has fixing threaded holes 220 for flywheel rotors of different specifications. Different sizes of rotors are fixed by double-headed hexagonal stainless steel studs, which achieves the purpose of strong versatility.
