Description

Technical Field

[0001] This utility model relates to the field of turbocharger technology, and more specifically, to the impeller of an integrated enhanced turbocharger. Background Technology

[0002] A turbocharger is an intake boosting device driven by engine exhaust energy. Its core function is to increase the engine's intake air volume by compressing air, thereby improving power output or optimizing fuel economy. It is widely used in internal combustion engine power systems of automobiles, construction machinery, and ships. The integrated enhanced turbocharger is an upgraded version of the traditional turbocharger, formed by structural integration and performance enhancement. Its core objectives are to improve boosting efficiency, reduce energy loss, optimize response speed, and adapt to more demanding working environments. The impeller is the core component of the turbocharger that directly transmits energy.

[0003] Existing impellers have fixed blade geometry, making it difficult to adapt to dynamic changes in gas flow. At low speeds, the energy capture efficiency decreases due to the mismatch between the blade angle of attack and the exhaust gas velocity, which can easily lead to turbine lag. At high speeds, excessive airflow impact on the blades increases eddy current losses and may even cause impeller vibration to intensify, limiting their applicability. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an impeller of an integrated enhanced turbocharger, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an impeller of an integrated enhanced turbocharger, comprising a connecting frame, multiple first blades, and a mounting base. The multiple first blades are fixedly connected to the mounting base, which is located at the top of the connecting frame. The connecting frame is provided with multiple adjusting components, one of which includes a first rotating shaft, a first bevel gear, a second bevel gear, a second rotating shaft, a second blade, a support plate, and a gear. The top and bottom ends of the first rotating shaft are movably connected to the connecting frame via bearings. The first bevel gear is fixedly sleeved on the first rotating shaft, with one side of the first bevel gear meshing with the second bevel gear. The other side of the second bevel gear is fixedly connected to the second rotating shaft. The second rotating shaft is movably connected to the connecting frame via bearings. A self-locking motor is fixedly connected to the bottom end of the connecting frame, and the output shaft end of the self-locking motor is fixedly connected to one of the first rotating shafts.

[0006] Furthermore, the support plate is movably connected to the second rotating shaft via a bearing, and both the top and bottom ends of the support plate are fixedly connected to the connecting frame.

[0007] Furthermore, the gear is fixedly sleeved on the first rotating shaft, and the gear is located at the top of the second bevel gear.

[0008] Furthermore, a second bolt is provided on the second blade, and the second blade is fixed to the second rotating shaft by the second bolt.

[0009] Furthermore, a bottom frame is movably provided on the outer side of the self-locking motor, and the top of the bottom frame is fixedly connected to the top of the connecting frame, and a connecting plate is fixedly connected to the bottom of the bottom frame.

[0010] As can be seen, in the above technical solution, the self-locking motor can be protected by the bottom frame, and the bottom frame can be easily installed on the external base by the connecting plate and bolts.

[0011] Furthermore, the mounting base is provided with a plurality of first bolts, and the mounting base and the connecting frame are fixed together by the plurality of first bolts.

[0012] Furthermore, a gasket is fixedly connected to the bottom of the mounting base, and the bottom end of the gasket is in contact with the connecting frame.

[0013] It can be seen that the above technical solution aims to improve the stability between the mounting base and the connecting frame.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. This utility model uses a self-locking motor to drive the first rotating shaft to rotate, which in turn drives the first bevel gear to rotate, and then drives the second blade to rotate. At the same time, the first rotating shaft can drive the gear to rotate, which in turn drives the other second blades to rotate synchronously. Similarly, the self-locking motor can reverse to drive multiple second blades to rotate in the opposite direction. The angle of multiple second blades can be adjusted according to the needs. The operation is simple, easy to adapt to the dynamic changes in gas flow, and has a wide range of applications.

[0016] 2. This utility model releases the fixation between the second blade and the second shaft by rotating the second bolt away from the second shaft, allowing the second blade to be disassembled and replaced. By rotating multiple first bolts in sequence away from the connecting frame, the fixation between the mounting base and the connecting frame is released, allowing the first blade to be disassembled and replaced. Similarly, the first blade is installed. The gasket can improve the stability between the mounting base and the connecting frame. The structure is simple and easy to use. Attached Figure Description

[0025] Refer to the instruction manual appendix Figure 1-3The impeller of the integrated enhanced turbocharger in this embodiment includes a connecting frame 1, multiple first blades 2, and a mounting base 3. The multiple first blades 2 are all fixedly connected to the mounting base 3, and the mounting base 3 is located on the top of the connecting frame 1. Multiple adjustment components 6 are provided on the connecting frame 1. One of the adjustment components 6 includes a first rotating shaft 602, a first bevel gear 603, a second bevel gear 604, a second rotating shaft 605, a second blade 606, a support plate 607, and a gear 608. The top and bottom ends of the first rotating shaft 602 are movably connected to the connecting frame 1 through bearings. The first bevel gear 603 is fixedly sleeved on the first rotating shaft 602, and one side of the first bevel gear 603 meshes with the second bevel gear 604. The other side of the second bevel gear 604 is fixedly connected to the second rotating shaft 605. The second rotating shaft 605 is movably connected to the connecting frame 1 through bearings. A self-locking motor 601 is fixedly connected to the bottom end of the connecting frame 1, and the output shaft end of the self-locking motor 601 is fixedly connected to one of the first rotating shafts 602.

[0026] Furthermore, the support plate 607 is movably connected to the second rotating shaft 605 via a bearing, and the top and bottom ends of the support plate 607 are fixedly connected to the connecting frame 1. The gear 608 is fixedly sleeved on the first rotating shaft 602, and the gear 608 is located on top of the second bevel gear 604.

[0027] Furthermore, a second bolt 7 is provided on the second blade 606, and the second blade 606 is fixed to the second rotating shaft 605 by the second bolt 7. A bottom frame 8 is movably provided on the outside of the self-locking motor 601, and the bottom frame 8 is fixedly connected to the top of the connecting frame 1. A connecting plate 5 is fixedly connected to the bottom of the bottom frame 8. A plurality of first bolts 4 are provided on the mounting base 3, and the mounting base 3 is fixed to the connecting frame 1 by the plurality of first bolts 4. A gasket 9 is fixedly connected to the bottom of the mounting base 3, and the bottom end of the gasket 9 is in contact with the connecting frame 1.

[0028] Specifically, rotating the second bolt 7 away from the second rotating shaft 605 releases the fixation between the second blade 606 and the second rotating shaft 605, allowing the second blade 606 to be disassembled and replaced. Then, rotating multiple first bolts 4 away from the connecting frame 1 releases the fixation between the mounting base 3 and the connecting frame 1, allowing the first blade 2 to be disassembled and replaced. Similarly, the first blade 2 is installed. The shim 9 improves the stability between the mounting base 3 and the connecting frame 1. The structure is simple and easy to use. The bottom frame 8 protects the self-locking motor 601, and the connecting plate 5 and bolts facilitate the installation of the bottom frame 8 onto the external base.

[0029] The usage method of this embodiment is as follows:

[0030] In use, the self-locking motor 601 is started, driving the first rotating shaft 602 to rotate, which in turn drives the first bevel gear 603 to rotate. Since the first bevel gear 603 meshes with the second bevel gear 604, it can drive the second bevel gear 604 and the second rotating shaft 605 to rotate, thus driving the second blades 606 to rotate. Simultaneously, the first rotating shaft 602 can drive gear 608 to rotate. Because multiple gears 608 mesh, one gear 608 can drive the others to rotate, thus causing the other second blades 606 to rotate synchronously. The self-locking motor 601 can reverse to drive multiple second blades 606 to rotate in the opposite direction. The angle of the multiple second blades 606 can be adjusted as needed. When the angle of the second blade 606 decreases, the cross-sectional area of ​​the gas passage shrinks, and the kinetic energy of the impact turbine increases, thereby reducing hysteresis. When the blade angle increases, the cross-sectional area of ​​the gas passage expands, avoiding excessive compression of exhaust gas that could cause turbine overspeed, thereby reducing engine power loss. It is simple to operate, easy to adapt to dynamic changes in gas flow, and has a wide range of applications. At the same time, the support plate 607 can support the second rotating shaft 605, thereby improving the stability of the second rotating shaft 605.
