Description

Technical Field

[0001] This utility model relates to the field of turbocharger technology, specifically to an oil-leakage-proof turbocharger. Background Technology

[0002] A turbocharger is essentially an air compressor that increases the intake air volume by compressing air. It uses the inertial force of the exhaust gas from the engine to drive a turbine in the turbine housing. The turbine, in turn, drives a coaxial impeller, which compresses the air supplied through the air filter and forces it into the cylinders.

[0003] Patent CN219754657U discloses a wear-resistant turbocharger, comprising a main body and a wear-resistant mechanism. The wear-resistant mechanism includes a titanium alloy impeller cavity, a titanium alloy impeller, a bearing, a bearing rotating shaft, and an oil film lubrication device. This device utilizes material optimization, surface treatment, and coating technologies to give the turbine and impeller higher hardness and wear resistance. The wear-resistant turbocharger can better maintain the clearance between the impeller and turbine, improving boosting efficiency.

[0004] However, the size of the titanium alloy blades inside the titanium alloy impeller cavity of this device is fixed. Depending on the engine displacement, a fixed model of turbocharger is difficult to meet the needs of engines with different displacements. If the increased power is not sufficient after installing an ordinary turbocharger into the turbocharger housing, it is necessary to select another model of turbocharger. To address this issue, an oil-leakage-proof turbocharger is proposed to solve the problem that existing turbochargers cannot automatically adjust the turbine size according to the engine displacement. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an oil-leakage-proof turbocharger, solving the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a leak-proof turbocharger, comprising a turbocharger housing, an intake pipe and an outlet pipe at one end of the turbocharger housing, a turbine chamber on the other side of the turbocharger housing, a turbine body inside the turbine chamber, multiple turbine blades outside the turbine body, a rotating shaft inside the turbine chamber, a cover on one side of the turbine body, the cover being connected to the turbine body by a bolt, a groove on one side of the cover, a bolt passing through the groove, a frustum inside the cover, symmetrical limiting grooves on the inner wall of the cover, limiting blocks inside the limiting grooves, the turbine body and the rotating shaft being connected by an installation mechanism, a movable groove on one inclined side of the frustum, a movable block slidably disposed inside the movable groove, and a limiting rod fixedly connected inside the movable groove.

[0007] Preferably, the turbine blade extends into the inner cavity of the turbine body and the two are slidably connected. The turbine blade is fixedly connected to the moving block, and the moving block is located on the outer ring of the limiting rod and the two are slidably connected.

[0008] Preferably, the two bolts penetrate the cover and are rotatably connected by a bearing at their intersection; the two bolts penetrate the inner wall of the frustum and are threadedly connected; and the limiting block is fixedly connected to the frustum.

[0009] Preferably, the mounting mechanism includes a mounting groove formed on one side of the turbine body, the rotating shaft is located in the inner cavity of the mounting groove, and the outer ring of the rotating shaft has a moving groove.

[0010] Preferably, the inner cavity of the movable groove is provided with a locking block and a spring. The locking block has a chamfer on one side boundary facing the rotating shaft. The inner wall of the mounting groove has symmetrical locking grooves. The two ends of the spring are fixedly connected to the locking block and the movable groove, respectively.

[0011] Preferably, the inner wall of the movable groove is provided with an anti-detachment groove, and the inner cavity of the anti-detachment groove is provided with an anti-detachment block. The anti-detachment block is fixedly connected to the locking block, and the spring is always in a compressed state.

[0012] Preferably, a sealing groove is provided at the intersection of the turbine blade and the turbine body, and a sealing sleeve is fixedly connected to the inner cavity of the sealing groove. The turbine blade passes through the sealing sleeve and the two are slidably connected.

[0013] 1. This leak-proof turbocharger utilizes a tool to rotate bolt two within the groove. This, in turn, causes the truncated cone to move to the left under the action of the limiting block within the limiting groove. Furthermore, under the action of the moving block and limiting rod within the moving groove, the turbine blades move outward from the turbine body, thereby increasing the overall turbine diameter and providing higher boost pressure. This increases the engine's power and torque, ensuring that the intake air volume meets the engine's power requirements. This solves the problem of existing turbochargers being unable to automatically adjust turbine size according to engine displacement.

[0014] 2. When installing the turbine body of this leak-proof turbocharger, insert the turbine body into the shaft through the mounting slot. During the process, with the help of the chamfer, the locking block moves into the moving slot and compresses the spring. When the moving slot and the locking slot are connected, the locking block enters the locking slot with the help of the spring force. Conversely, press the turbine body towards the shaft, and with the help of the chamfer, move the locking block into the moving slot and rotate it to remove the turbine body, which improves the convenience of turbine installation and removal.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Please refer to Figure 1-5 A leak-proof turbocharger includes a turbocharger housing 1. One end of the turbocharger housing 1 is provided with an intake pipe 2 and an exhaust pipe 3. The other side of the turbocharger housing 1 is provided with a turbine chamber 5. The inner cavity of the turbine chamber 5 is provided with a turbine body 6. The outer side of the turbine body 6 is provided with multiple turbine blades 7. The inner cavity of the turbine chamber 5 is provided with a rotating shaft 8. One side of the turbine body 6 is provided with a cover 10. The cover 10 is connected to the turbine body 6 by a bolt 9. A groove 11 is opened on one side of the cover 10. A bolt 12 is inserted through the groove 11. The inner cavity of the cover 10 is provided with a frustum 13. The inner wall of the cover 10 is provided with symmetrical limiting grooves 14. The inner cavity of the limiting grooves 14 is provided with limiting blocks 15. The turbine body 6 and the rotating shaft 8 are connected by an installation mechanism 16. A linkage groove 17 is opened on one inclined surface of the frustum 13. A moving block 4 is slidably provided in the inner cavity of the linkage groove 17. A limiting rod 18 is fixedly connected to the inner cavity of the linkage groove 17.

[0023] Furthermore, the turbine blade 7 extends into the inner cavity of the turbine body 6 and the two are slidably connected. The turbine blade 7 is fixedly connected to the moving block 4, which is located on the outer ring of the limiting rod 18 and the two are slidably connected.

[0024] Furthermore, bolt 12 penetrates the cover 10 and the intersection of the two is limited by a bearing and is rotatably connected. Bolt 12 penetrates the inner wall of the frustum 13 and the two are threadedly connected. The limiting block 15 is fixedly connected to the frustum 13.

[0025] Furthermore, the mounting mechanism 16 includes a mounting groove 166 formed on one side of the turbine body 6, the rotating shaft 8 is located in the inner cavity of the mounting groove 166, and the outer ring of the rotating shaft 8 is provided with a moving groove 161.

[0026] Furthermore, the inner cavity of the moving groove 161 is provided with a locking block 162 and a spring 163. The locking block 162 has a chamfer 164 on one side boundary facing the rotating shaft 8. The inner wall of the mounting groove 166 has symmetrical locking grooves 165. The two ends of the spring 163 are fixedly connected to the locking block 162 and the moving groove 161 respectively. When installing the turbine body 6, the turbine body 6 is inserted into the rotating shaft 8 through the mounting groove 166. During the process, with the help of the chamfer 164, the locking block 162 moves into the moving groove 161 and compresses the spring 163. When the moving groove 161 and the locking groove 165 are interconnected, with the help of the elastic force of the spring 163, the locking block 162 enters the locking groove 165. Conversely, the turbine body 6 is pressed towards the rotating shaft 8. With the help of the chamfer 164, the locking block 162 is moved into the moving groove 161 and then rotated, so that the turbine body 6 can be disassembled, which improves the convenience of turbine installation and disassembly.

[0027] Furthermore, the inner wall of the moving groove 161 is provided with an anti-detachment groove 167, and an anti-detachment block 168 is provided in the inner cavity of the anti-detachment groove 167. The anti-detachment block 168 is fixedly connected to the locking block 162. The spring 163 is always in a compressed state. Under the action of the spring 163 in a compressed state and the anti-detachment block 168 in the anti-detachment groove 167, the locking block 162 is always located in the locking groove 165. At the same time, when the rotating shaft 8 is driven to rotate, the locking block 162 has an outward force under the action of centrifugal force, which further ensures the stability of the turbine body 6 after installation.

[0028] Furthermore, a sealing groove 19 is provided at the intersection of the turbine blade 7 and the turbine body 6. A sealing sleeve 20 is fixedly connected to the inner cavity of the sealing groove 19. The turbine blade 7 passes through the sealing sleeve 20 and the two are slidably connected. The sealing sleeve 20 in the sealing groove 19 increases the sealing between the turbine blade 7 and the turbine body 6, thereby preventing oil from leaking into the turbine body 6 when engine exhaust gas enters the turbine cavity 5, which would affect the subsequent adjustment of the turbine blade 7.

[0029] Working principle: When using this leak-proof turbocharger, if it is necessary to increase the engine intake air volume, use a tool to rotate the bolt 12 in the groove 11. Then, under the action of the limiting block 15 in the limiting groove 14, the truncated cone 13 is moved to the left. Then, under the action of the moving block 4 and the limiting rod 18 in the linkage groove 17, the turbine blades 7 are moved to the outside of the turbine body 6, thereby increasing the overall diameter of the turbine, providing higher boost pressure, thereby increasing the engine power and torque, so that the intake air volume meets the engine power requirements, and solving the problem that existing turbochargers cannot adjust the turbine size according to the engine displacement.
