Abstract
Description
Technical Field
[0001] This utility model relates to the field of turbocharger technology, and in particular to a durable turbocharger. Background Technology
[0002] In the field of modern power equipment, turbochargers play a crucial role in automobiles, ships, and industrial engines. They utilize the energy from engine exhaust gases to drive a turbine, which in turn drives a coaxial impeller to compress air, increasing the engine's intake air volume. This increased intake air volume allows the engine to burn more fuel, significantly improving its power and torque.
[0003] Existing durable turbochargers, if they do not have a structure for quick installation and removal of the impeller body or turbine blades, require technicians to spend a lot of time and effort to remove the relevant components during maintenance. Due to the lack of a convenient disassembly method, complex operating procedures may be required, such as removing multiple related components to access the impeller body or turbine blades, which greatly increases the labor costs of maintenance. Therefore, we propose a durable turbocharger to solve this problem. Utility Model Content
[0004] The purpose of this invention is to provide a durable turbocharger to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A durable turbocharger includes: an intermediate body, on both sides of which a turbine housing and an impeller housing are fixedly mounted respectively; a rotating shaft is rotatably mounted inside the intermediate body; connecting shaft seats are fixedly mounted at both ends of the rotating shaft; connecting columns are movably inserted into the interior of each of the two sets of connecting shaft seats; conical blocks are slidably mounted inside the interior of each of the two sets of connecting columns; inclined rods abut against the outer sides of each of the two sets of conical blocks; two sets of inclined rods on the same side are slidably mounted on corresponding connecting columns; two sets of inclined rods on the same side are movably inserted into the interior of the connecting shaft seats; a screw is fixedly mounted on one side of each of the two sets of conical blocks; turbine blades and impeller bodies are slidably mounted on the outer sides of each of the two sets of screws respectively.
[0007] Preferably, a limiting circular plate is fixedly installed on the outer side of each of the four sets of inclined rods, and a return spring is fixedly installed on one side of each of the four sets of limiting circular plates. The turbine blade and the impeller body are fixedly installed on one side of the corresponding connecting column. The turbine blade is disposed in the turbine housing, and the impeller body is disposed in the impeller housing.
[0008] Preferably, each of the two sets of connecting shafts has two sets of slots inside, and the four sets of inclined rods are slidably installed in the corresponding slots. The outer sides of the two sets of screws are threaded with two sets of anti-slip nuts, and the two sets of anti-slip nuts respectively abut against the impeller body and the turbine blade.
[0009] Preferably, each of the two sets of connecting columns has two sets of limiting grooves inside, the four sets of inclined rods and the corresponding limiting circular plates are slidably installed in the corresponding limiting grooves, and one end of the four sets of reset springs is fixedly installed on one side of the corresponding limiting groove.
[0010] Preferably, both sets of connecting columns have guide grooves inside, and the two sets of conical blocks are slidably installed in the corresponding guide grooves.
[0011] Preferably, the coupling seat has an internal mounting groove, and the two sets of connecting columns are movably inserted into the corresponding mounting grooves.
[0012] In this utility model, a durable turbocharger is described. When the engine is running, it produces high-temperature and high-pressure exhaust gas. This exhaust gas is discharged into the turbine housing. Inside the turbine housing, the turbine blades rotate, which in turn drives the impeller body to rotate synchronously through the rotating shaft. This process is the initial power source for the entire turbocharger's operation, successfully converting the energy of the exhaust gas into mechanical rotational power in the initial stage.
[0013] This utility model features a reasonable structural design. By setting two sets of anti-slip nuts connected to the screw threadedly, the anti-slip screw can be removed by tightening the anti-slip nuts, releasing the screw from its restriction. The conical body abuts against the corresponding inclined rod, and under the elastic force of the return spring, the two sets of limiting plates drive the corresponding two sets of inclined rods to move within their respective limiting grooves. This disengages the two sets of inclined rods from the connecting shaft seat, releasing the locking setting between the connecting shaft seat and the connecting column. This allows the connecting column to be disassembled from the corresponding turbine blade or impeller body. Conversely, it can be quickly installed and fixed by tightening the bolts. Maintenance personnel can quickly disassemble faulty parts for repair or replacement without the need for complex tools or cumbersome procedures, effectively shortening equipment downtime, improving equipment utilization, and enabling the equipment to return to normal operation as soon as possible.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Reference Figure 1-5 A durable turbocharger includes: an intermediate body 1, on which a turbine housing 2 and an impeller housing 3 are fixedly installed respectively on both sides; a rotating shaft 5 is rotatably installed inside the intermediate body 1; connecting shaft seats 6 are fixedly installed at both ends of the rotating shaft 5; connecting columns 7 are movably inserted into the interior of each of the two sets of connecting shaft seats 6; conical blocks are slidably installed inside the interior of each of the two sets of connecting columns 7; inclined rods 12 abut against the outer sides of each of the two sets of conical blocks; two sets of inclined rods 12 on the same side are slidably installed on corresponding connecting columns 7; two sets of inclined rods 12 on the same side are movably inserted into the interior of the connecting shaft seats 6; screws 9 are fixedly installed on one side of each of the two sets of conical blocks 11; turbine blades 4 and impeller bodies 8 are slidably installed on the outer sides of the two sets of screws respectively.
[0022] In this embodiment, a limiting circular plate 13 is fixedly installed on the outer side of each of the four sets of inclined rods 12, and a return spring 14 is fixedly installed on one side of each of the four sets of limiting circular plates 13. The turbine blade 4 and the impeller body 8 abut against one side of the corresponding connecting column 7. The turbine blade 4 is disposed in the turbine housing 2, and the impeller body 8 is disposed in the impeller housing 3. The limiting circular plate 13 can limit the sliding range of the inclined rod 12, prevent the inclined rod 12 from sliding excessively during operation and leaving the normal working position, and ensure the stability of the movement of the inclined rod 12.
[0023] In this embodiment, two sets of slots are provided inside the two sets of connecting shafts. Four sets of inclined rods 12 are slidably installed in the corresponding slots. Two sets of anti-slip nuts 10 are threadedly connected to the outer side of the two sets of screws. The two sets of anti-slip nuts 10 respectively abut against the impeller body 8 and the turbine blade 4. The slots provide precise guidance for the sliding of the inclined rods 12, so that the inclined rods 12 can only slide in a specific direction during the transmission of power.
[0024] In this embodiment, two sets of limiting grooves are provided inside the two sets of connecting columns 7. The four sets of inclined rods 12 and the corresponding limiting circular plates 13 are slidably installed in the corresponding limiting grooves. One end of the four sets of return springs 14 is fixedly installed on one side of the corresponding limiting groove, so that the movement of the inclined rods 12 is more stable and precise.
[0025] In this embodiment, guide grooves are provided inside both sets of connecting columns 7, and the two sets of conical blocks are slidably installed in the corresponding guide grooves to avoid shaking or displacement, thereby improving the efficiency and accuracy of power transmission.
[0026] In this embodiment, the shaft seat has an internal mounting groove, and the two sets of connecting columns 7 are movably inserted into the corresponding mounting grooves, which improves the efficiency of production and maintenance.
[0027] In this embodiment, during use, the anti-slip screw is removed by unscrewing the two sets of anti-slip nuts 10 from one end of the screw, thereby releasing the restriction on the screw. The conical body 11 abuts against the corresponding inclined rod 12, and under the elastic force of the return spring 14, the two sets of limiting circular plates 13 drive the corresponding two sets of inclined rods 12 to move in the corresponding limiting grooves, thereby disengaging the two sets of inclined rods 12 from the connecting shaft seat 6, releasing the locking setting between the connecting shaft seat 6 and the connecting column 7, thereby allowing the connecting column 7 to be removed from the corresponding turbine blade 4 or impeller body 8. Conversely, it can be quickly installed and fixed by tightening the bolt 9.
[0028] When the engine is running, it produces high-temperature, high-pressure exhaust gas. This exhaust gas is discharged into the turbine housing 2. Inside the turbine housing 2, the turbine blades 4 rotate, which in turn drives the impeller body 8 to rotate synchronously via the rotating shaft 5. This process is the initial power source for the entire turbocharger, successfully converting the energy of the exhaust gas into mechanical rotational power. The above provides a detailed description of a durable turbocharger provided by this utility model. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only intended to help understand the method and core idea of this utility model. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
