[0002] In equipment such as automobiles, ships, and generator sets, the engine and generator or transmission are generally two separate parts. However, the generator or transmission requires the engine's power to function properly. Therefore, a connection must be established between the two. Current connection methods typically use the engine's flywheel. The flywheel and generator or transmission are generally rigidly connected; the outer ring of the flywheel connects to the generator or transmission, and the inner ring connects to the engine's crankshaft. Figure 1 As shown, the inner ring 1 and outer ring 4 of the flywheel are usually integrally molded structures, which are rigid connection structures. This makes the entire shaft system prone to resonance or increased overall vibration of the two components during operation, which can lead to component damage. This results in frequent component damage and high maintenance costs. Utility Model Content

[0019] The present invention will be further described below with reference to specific embodiments shown in the accompanying drawings.

[0020] See Figure 2-3As shown, a flexible flywheel assembly of this utility model includes an inner connecting plate 1. A first groove 2 is formed on one side of the inner connecting plate 1, and multiple connecting holes 3 for connecting an engine crankshaft are formed at the bottom of the first groove 2. An outer connecting plate 4 for connecting a generator or gearbox is provided on the outer side of the inner connecting plate 1. A second groove 5 is formed on one side of the outer connecting plate 4, and a spring steel sheet 6 is provided between the bottom of the second groove 5 and the inner connecting plate 1. The inner and outer rings of the spring steel sheet 6 are detachably connected to the inner connecting plate 1 and the outer connecting plate 4, respectively. A toothed ring 10 is provided on the other side of the outer connecting plate 4. By setting the flywheel as an external connecting plate... The outer connecting plate 4 and the inner connecting plate 1 are connected together by spring steel sheet 6 and connecting bolt 12. The crankshaft of the engine is connected to the inner connecting plate 1 by bolts. The generator or gearbox is connected to the outer connecting plate 4. During use, the vibration of the engine shaft system and the vibration of the generator or gearbox shaft system are buffered by the spring steel sheet 6, which effectively reduces the mutual vibration influence and avoids resonance and other problems. This ensures that the components are less affected by resonance, protects the components, extends their service life, reduces the occurrence of failures, and reduces maintenance costs.

[0021] Specifically, the spring steel sheet 6 has multiple arc-shaped long slots 8 arranged around it, which reduces weight and disperses the internal stress of the spring steel sheet 6, avoiding stress concentration, thereby preventing the spring steel sheet 6 from breaking or deforming when subjected to force.

[0022] Preferably, the outer connecting plate 4 has multiple mounting holes 9 for connecting the generator or gearbox. The multiple mounting holes 9 are arranged in a ring on the outer connecting plate 4, which can be evenly stressed when connected to the generator or gearbox, ensuring the reliability of the connection.

[0023] Furthermore, the spring steel sheet 6 is composed of several thin steel sheets stacked together. The appropriate thickness can be selected according to actual needs. Different thin steel sheets can distribute stress and prevent the spring steel sheet 6 from breaking or deforming when subjected to force.

[0024] Furthermore, the spring steel sheet 6 is connected to the inner connecting plate 1 and the outer connecting plate 4 by multiple connecting bolts 12, and the connecting bolts 12 are used for detachable connection, which facilitates installation and disassembly.

[0025] Furthermore, a pressure ring 7 is provided on the inner ring of the spring steel sheet 6. The connecting bolt 12 passes through the pressure ring 7 and the spring steel sheet 6 in sequence and is threadedly connected to the inner connecting plate 1, so that the pressure ring 7 can effectively press and install the spring steel sheet 6 to prevent the spring steel sheet 6 from loosening and make the connection more secure.

[0026] Furthermore, a locking bolt 11 is provided between the gear ring 10 and the outer connecting plate 4. The locking bolt 11 passes through the gear ring 10 and is threadedly connected to the outer connecting plate 4, which facilitates the installation and disassembly of the gear ring 10 and ensures a firm and stable connection structure.

[0027] Furthermore, the outer ring of the outer connecting plate 4 is provided with multiple detection holes 13 for detecting the position of the engine crankshaft, which are used by the ECU to monitor the position of the engine crankshaft and thus control the nozzle to inject diesel fuel.

[0028] In this embodiment, a flexible flywheel assembly is used by configuring the flywheel as an outer connecting plate 4 and an inner connecting plate 1, which are connected together by spring steel sheets 6 and connecting bolts 12. The crankshaft of the engine is connected to the inner connecting plate 1 by bolts, and the generator or gearbox is connected to the outer connecting plate 4. During use, the vibration of the engine shaft system and the vibration of the generator or gearbox shaft system are buffered by the spring steel sheets 6, effectively reducing the mutual vibration influence and avoiding resonance problems. This ensures that the components are protected from resonance, extends their service life, reduces the occurrence of failures, and lowers maintenance costs. This flexible flywheel assembly of the present invention reduces the mutual vibration influence, avoids resonance problems, and extends the service life of components, and has the characteristics of wide applicability and strong practicality.
