Description

Technical Field

[0001] This utility model belongs to the field of gasoline engine flywheel technology, and in particular relates to a flywheel assembly for a single-cylinder gasoline engine. Background Technology

[0002] A single-cylinder gasoline engine is an internal combustion engine containing only one cylinder. It is characterized by its simple structure, low manufacturing cost, and convenient maintenance. The flywheel is a key component of a gasoline engine, and its function is similar to an energy storage device. When the gasoline engine is working, the flywheel stores the kinetic energy generated by the engine through its rotational inertia, and then releases it when needed to maintain the stable operation of the engine.

[0003] In the application of existing single-cylinder gasoline engine flywheels, the multiple sets of blades on the outer edge for heat dissipation and speed balancing are prone to wear, deformation, or even breakage after long-term use due to structural limitations. This can lead to blade imbalance and even affect the normal operation of the flywheel. There is a technical problem that the structure of the flywheel cannot be strengthened from the base of the air guide blades to make it more reliable and durable. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a single-cylinder gasoline engine flywheel assembly, which can effectively solve the problems of the existing technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a flywheel assembly for a single-cylinder gasoline engine, comprising a flywheel body, guide vanes disposed on the flywheel body and on the front edge of the flywheel body, and further comprising:

[0007] A connecting plate is disposed inside the air guide vanes at the front end of the flywheel body. A stabilizing bracket is provided at the front end of the connecting plate, and an installation structure is provided between the inner side of the connecting plate and the front end of the flywheel body.

[0008] The keyway is installed in the middle position inside the flywheel body. The guide vanes are arc-shaped and are arranged at equal intervals at the front edge of the flywheel body.

[0009] An inertia adjustment component is located at the rear end inside the flywheel body.

[0010] Furthermore, the connecting plate is annular, and the stabilizing brackets are arranged at equal intervals at the front end of the connecting plate, and the stabilizing brackets are snapped onto the outside of the guide vanes.

[0011] Furthermore, the mounting structure includes an assembly lug, a fixing screw hole, and a mounting bolt. The assembly lug is disposed on the inner side of the connecting plate, and the mounting bolt passes through the interior of the assembly lug. The fixing screw hole is disposed at the front end of the flywheel body, and the rear end of the mounting bolt is inserted into the interior of the fixing screw hole.

[0012] Furthermore, the guide vanes are arc-shaped and are arranged at equal intervals at the front edge of the flywheel body.

[0013] Furthermore, the inertia adjustment component includes an auxiliary counterweight, a positioning slot, a fixing pin, and a buffer pad. The auxiliary counterweight is located at the rear end of the inner side of the flywheel body, the positioning slot is located at the rear end of the inner side of the flywheel body, a fixing pin is located at the middle position of the outer side of the auxiliary counterweight, and buffer pads are located at both ends of the outer side of the auxiliary counterweight.

[0014] Furthermore, the auxiliary counterweight is arc-shaped, the positioning slots are arranged at equal intervals on the inner side of the flywheel body, and the fixing pin is fitted inside the positioning slot.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model provides a reinforcing and stabilizing component on the outer side of the air guide blade at the front end of the flywheel body. During use, the stabilizing bracket at the front end of the connecting plate is snapped onto the outer side of the air guide blade, and the connecting plate is securely connected to the front end of the flywheel body using the installation structure. This strengthens the air guide blade from the root, reducing the probability of deformation or even breakage of the air guide blade after long-term use, thereby ensuring the safe and stable operation of the single-cylinder gasoline engine and making the single-cylinder gasoline engine more reliable and durable.

[0017] 2. This utility model has an inertia adjustment component set at the rear end of the inner side of the flywheel body. In use, the auxiliary counterweight can be positioned and installed inside the flywheel body by inserting the fixing pin into the positioning slot. The inertia of the gasoline engine flywheel can be adjusted by increasing or decreasing the number of auxiliary counterweights and adjusting the installation position, thereby reducing the speed fluctuation of the mechanical system. In addition, the buffer pad can buffer and dampen the vibration to avoid the centrifugal force generated by the high-speed rotation of the flywheel causing the auxiliary counterweight to collide with the inner side of the flywheel body and make abnormal noise.

[0025] 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.

[0026] Please see Figure 1-4 As shown, this utility model is a flywheel assembly for a single-cylinder gasoline engine, including a flywheel body 1, a counterweight 3 disposed on one side of the flywheel body 1, and a guide vane 2 disposed at the front edge of the flywheel body 1, and further including:

[0027] The keyway 5 is located in the middle of the flywheel body 1. The flywheel body 1 is mounted on the crankshaft of the gasoline engine through the keyway 5. The guide vanes 2 are arc-shaped and are arranged at equal intervals at the front edge of the flywheel body 1. When the gasoline engine is working, the flywheel body 1 stores and releases energy through rotational inertia to ensure the engine runs smoothly. The guide vanes 2 are used to balance the engine power output, and the counterweight 3 is used to balance the rotating mass, reduce vibration and noise, and improve the stability and reliability of the engine.

[0028] As a further implementation of this embodiment, such as Figure 1 , Figure 3 and Figure 4As shown, the connecting plate 6 is located inside the guide vane 2 at the front end of the flywheel body 1, and the connecting plate 6 is annular. A stabilizing bracket 4 is provided at the front end of the connecting plate 6. The stabilizing brackets 4 are arranged at equal intervals at the front end of the connecting plate 6 and are engaged with the outside of the guide vane 2. The connecting plate 6 and the stabilizing brackets 4 engaged with the base of the guide vane 2 provide structural reinforcement to reduce the probability of deformation or even breakage of the guide vane 2 after prolonged use. The connection plate 6 and the front end of the flywheel body 1 are connected... An installation structure is provided, which includes an mounting ear plate 13, a fixing screw hole 11, and a mounting bolt 12. The mounting ear plate 13 is located inside the connecting plate 6, and the mounting bolt 12 passes through the inside of the mounting ear plate 13. The fixing screw hole 11 is located at the front end of the flywheel body 1, and the rear end of the mounting bolt 12 is inserted into the inside of the fixing screw hole 11. After the connecting plate 6 and the stabilizing bracket 4 are installed in place, the mounting bolt 12 is tightened through the mounting ear plate 13 into the fixing screw hole 11 to secure the connecting plate 6 and the stabilizing bracket 4.

[0029] Before installing the flywheel onto the crankshaft, first install the annular connecting plate 6 on the inner side of the air guide blade 2 at the front end of the flywheel body 1. At the same time, align the mounting ear plate 13 on the inner side of the connecting plate 6 with the fixing screw holes 11 at the front end of the flywheel body 1. Simultaneously, the stabilizing bracket 4 fixedly connected to the front end of the connecting plate 6 is snapped onto the outer side of the air guide blade 2. Then, insert the mounting bolts 12 through the mounting ear plate 13 and tighten them into the fixing screw holes 11 through the threaded connection to securely install the connecting plate 6 and the stabilizing bracket 4 at the front end of the flywheel body 1. The connecting plate 6 and the stabilizing bracket 4 are used to strengthen the structure of the air guide blade 2, making it more durable and less prone to deformation and damage.

[0030] As a further implementation of this embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the inertia adjustment component is located at the rear end of the inner side of the flywheel body 1. The inertia adjustment component includes an arc-shaped auxiliary counterweight 7, a positioning slot 8, a fixing pin 9, and a buffer pad 10. The auxiliary counterweight 7 is located at the rear end of the inner side of the flywheel body 1. The positioning slot 8 is located inside the flywheel body 1 and is arranged at equal intervals on the inner side of the flywheel body 1. A fixing pin 9 is provided at the middle position of the outer side of the auxiliary counterweight 7. The fixing pin 9 is engaged with the rear end of the inner side of the positioning slot 8. By engaging the fixing pin 9 with the positioning slot 8, the auxiliary counterweight 7 can be installed on the inner side of the flywheel body 1. The position of the auxiliary counterweight 7 on the inner side of the flywheel body 1 can be adjusted by inserting it into the positioning slot 8 at different positions, thereby adjusting the inertia of the flywheel body 1 and reducing the speed fluctuation of the mechanical system. Buffer pads 10 are provided at both ends of the outer side of the auxiliary counterweight 7. The buffer pads 10 can be used to buffer and dampen shock to prevent the auxiliary counterweight 7 from hitting and contacting the inner side of the flywheel body 1 and causing abnormal noise.

[0031] In use, the fixing pin 9 located at the middle of the outer side of the auxiliary counterweight 7 is inserted into the positioning slot 8 located on the inner side of the flywheel body 1 to position and install the auxiliary counterweight 7 on its inner side. By increasing or decreasing the number of auxiliary counterweights 7 installed and adjusting the fixing pin 9 to be inserted and fixed in different positions of the positioning slot 8, the position of the auxiliary counterweight 7 installed on the inner side of the flywheel body 1 can be adjusted, thereby adjusting the moment of inertia of the gasoline engine flywheel. The buffer pads 10 located at both ends of the outer side of the auxiliary counterweight 7 are used to prevent the centrifugal force generated by the high-speed rotation of the flywheel from causing the outer side of the auxiliary counterweight 7 to collide with the inner side of the flywheel body 1.

[0032] Working principle: When using the single-cylinder gasoline engine flywheel assembly, before installing the flywheel, install the connecting plate 6 on the inner side of the guide vane 2, align the mounting ear plate 13 with the fixing screw hole 11, and snap the stabilizing bracket 4 onto the outer side of the guide vane 2. Then, pass the mounting bolts 12 through the mounting ear plate 13 and tighten them into the fixing screw hole 11 to securely install the connecting plate 6 and the stabilizing bracket 4 at the front end of the flywheel body 1. Adjust the number of auxiliary counterweights 7 and the position of the fixing pins 9 according to the working state of the gasoline engine flywheel. The auxiliary counterweight 7 can be installed inside the flywheel body 1 by inserting and fixing it into the positioning slot 8, thereby adjusting the moment of inertia of the gasoline engine flywheel. Then, the flywheel body 1 can be installed on the crankshaft of the gasoline engine through the mounting keyway 5. When the gasoline engine is working, the flywheel body 1 stores and releases energy through rotational inertia to ensure the smooth operation of the engine. The guide vanes 2 are used to balance the power output of the engine. The structure of the guide vanes 2 is reinforced by the connecting plate 6 and the stabilizing bracket 4 to make it more durable and less prone to deformation and damage, thereby ensuring the safe and stable operation of the flywheel assembly.

[0033] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
