[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Example: Reference Figure 1-4The diagram illustrates an engine flywheel structure, comprising a flywheel body 1. A first annular protrusion 2 is provided on the outer side of the flywheel body 1, and a threaded hole is formed on the outer side of the first annular protrusion 2. The first annular protrusion 2 enhances the structural strength of the flywheel body 1, making the flywheel more stable during high-speed rotation and reducing the possibility of deformation. A pair of wear-resistant components are provided on the outer side of the first annular protrusion 2; the wear-resistant components include friction plates 3 disposed on the outer side of the flywheel body 1. The friction plates 3 are mainly used to generate friction when in contact with other components, playing a role in braking or transmitting power, etc., thereby achieving energy conversion or controlling the speed of the flywheel through friction. The friction plate 3 has a slot 7 on its inner side, and a rotating rod 8 is rotatably connected to the inner wall of the slot 7. The rotating rod 8 can rotate flexibly within the slot 7 to adapt to different working conditions and stress conditions. A groove 13 is provided on the outer side of the rotating rod 8. The groove 13 may be used to install other auxiliary components or cooperate with other parts to play a role in positioning, guiding, etc. One end of the rotating rod 8 is fixedly connected to a threaded rod 11. The flywheel body 1 has a threaded hole 12 that matches the threaded rod 11 on its inner side. Through the cooperation of the threaded rod 11 and the threaded hole 12, the wear-resistant components can be easily installed on the flywheel body 1, and connected... The connection is firm and not easily loosened; a transmission sleeve 6 is provided on the inner side of the flywheel body 1, and an internal spline is provided on the inner wall of the transmission sleeve 6. The internal spline can cooperate with other shaft parts with external splines to achieve precise power transmission, ensuring the efficiency and stability of power transmission, so that the engine power can be accurately transmitted to other transmission components; multiple connecting holes 9 are opened on the inner side of the flywheel body 1, which are used to connect the flywheel body 1 to other components, such as the crankshaft of the engine, to ensure that the flywheel is fixed in position and reliably connected in the engine system; multiple weight-reducing grooves are opened on the outer side of the flywheel body 1. 10. The weight-reducing groove 10 can reduce the weight of the flywheel without affecting its overall strength and performance, thereby reducing the engine's rotational inertia, making the engine's acceleration and deceleration processes more sensitive, and improving the engine's working efficiency. A fixing ring 4 is fixedly connected to the outer side of the flywheel body 1, and multiple gear teeth 5 are fixedly connected to the outer side of the fixing ring 4. These gear teeth 5 can mesh with other gears or toothed components to achieve power conversion or change the transmission ratio, playing a key role in the engine's starting system or transmission system, such as meshing with the starter motor gear to start the engine. Multiple gear teeth 5 are fixedly connected to the outer side of the flywheel body 1. A reinforcing rib 14 is fixedly connected to the transmission sleeve 6. The reinforcing rib 14 can effectively enhance the structural strength of the flywheel body 1, especially when subjected to large torque and centrifugal force, to prevent the flywheel body 1 from cracking or being damaged, and to ensure the safe and stable operation of the engine. A second annular protrusion 15 is fixedly connected to the outer side of the flywheel body 1. Both the first annular protrusion 2 and the second annular protrusion 15 are made of carbon cast steel. Carbon cast steel has high strength and wear resistance, and can withstand various stresses and frictions of the flywheel during operation, extending the service life of the flywheel and ensuring the reliability and durability of the flywheel structure.

[0023] In this embodiment, when the friction plate 3 contacts the clutch, the engine power is transmitted through friction. By simultaneously turning the two rotating rods 8 with a pair of screwdrivers, the rotating rods 8 drive the threaded rod 11 to rotate, disconnecting the threaded rod 11 from the threaded hole 12, thus enabling the corresponding friction plate 3 to be disassembled. The first annular protrusion 2 and the second annular protrusion 15 are designed with a set rotational inertia, and the recessed disc structure effectively stores and releases the rotational inertia. The weight reduction groove 10 effectively adjusts the rotational inertia of the flywheel and reduces the overall weight, thereby improving the engine operating efficiency.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
