Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of turbochargers, and more specifically, to a wear-resistant turbocharger. Background Art
[0002] The engine is the power source of the car. The engine outputs power by burning fuel in the cylinder. Since the amount of fuel input is limited by the amount of air inhaled into the cylinder, the power output of the engine is limited under the premise of a certain cylinder capacity. Turbocharging can compress more air into the cylinder to increase fuel, thereby improving the engine's ability to burn and work without changing the cylinder capacity. The turbocharger is mainly composed of a turbine chamber and a boost chamber. The turbine chamber is equipped with a turbine, and the boost chamber is equipped with an impeller. The turbine and the impeller are connected by a rotating shaft. The air inlet of the turbine chamber is used to receive the exhaust gas generated by the engine, thereby driving the turbine to rotate, and through the rotating shaft, driving the impeller in the boost chamber to rotate, and compressing more air into the cylinder for combustion.
[0003] Among them, the patent with patent application number CN202120254672.0 discloses a wear-resistant turbocharger, which includes an intermediate chamber, a shaft sleeve is fixed in the intermediate chamber, a coaxial rotating shaft is passed through the shaft sleeve, a liquid storage tank and a guide groove for storing lubricating oil are provided in the intermediate chamber, the guide groove is communicated with the liquid storage tank, and the end of the guide groove away from the liquid storage tank leads to the connection between the shaft sleeve and the rotating shaft, and the guide groove is used to introduce the lubricating oil into the connection between the shaft sleeve and the rotating shaft; a slide groove is opened in the intermediate chamber, the slide groove passes through the guide groove, and the slide groove is slidably connected to a connecting rod, the connecting rod can slide along the length direction of the slide groove, and the connecting rod is connected to the rotating shaft through a bevel gear, and the bevel gear is used to convert the rotational motion of the rotating shaft into the reciprocating motion of the connecting rod;
[0004] When the structure is in use, if the amount of lubricating oil in the liquid storage tank is small, the lubricating oil can flow along the inclined surface to the guide groove, thereby improving the utilization rate of the lubricating oil and thus improving its anti-wear performance. However, the structure is not easy to limit the various structures when in use, and the device will vibrate during long-term operation, causing the structure to loosen, resulting in reduced anti-wear performance.

[0010] It can be seen that in the above technical solution, the positioning sleeve rubs against the central lubricating sleeve when rotating, and the conical section at the end of the positioning sleeve allows the positioning sleeve to be clamped in the middle of the central lubricating sleeve, while preventing the positioning sleeve from shaking when it is shaken, reducing wear and ensuring its stability. The first locking ring and the second locking ring are limited by the constraint ring, and the spacer ring can separate the first locking ring and the second locking ring, preventing the second turbine from rotating and shaking the second guide chamber due to resistance and transmitting it to the first guide chamber, ensuring the stability of each structure during operation and improving the wear resistance of the structure.

[0013] By setting the limit connection assembly, compared with the prior art, the overall design is simple and the structure is reasonable. Through the corresponding coordinated use of various structures, the positioning sleeve is set on the outside of the reinforced horizontal shaft, so that when the reinforced horizontal shaft rotates, the positioning sleeve is driven to rotate.

Through the conical section at the end of the positioning sleeve, the positioning sleeve can be clamped in the middle of the central lubricating sleeve, while avoiding the shaking of the positioning sleeve when it is shaken, reducing wear and ensuring its stability.
[0014] The first locking ring and the second locking ring are limited by the constraint ring, and the spacer ring can separate the first locking ring and the second locking ring, which not only ensures the stability of the installation of the second guide chamber, but also prevents the second turbine from rotating and causing resistance and shaking in the second guide chamber, which is transmitted to the first guide chamber, thereby ensuring the stability of each structure during operation and improving the wear resistance of the structure.

[0024] The limit connection assembly includes a first flow guiding chamber 2 arranged at one end of the support cylinder 1, and a second flow guiding chamber 3 is arranged at the other end of the support cylinder 1, and the support cylinder 1, the first flow guiding chamber 2 and the second flow guiding chamber 3 are connected;
[0025] A central lubricating sleeve 4 is provided in the middle of the supporting cylinder 1, and a reinforcing transverse shaft 5 is rotatably connected to the middle of the central lubricating sleeve 4;
[0026] A restraining collar 9 is sleeved on the outer side of the support cylinder 1, a first locking ring 10 is provided at one end of the second flow guide chamber 3 facing the support cylinder 1, a second locking ring 11 is provided at one end of the support cylinder 1 facing the second flow guide chamber 3, the first locking ring 10 is located on one side of the second locking ring 11, the first locking ring 10 and the second locking ring 11 are both located in the middle of the restraining collar 9, a spacer ring 12 is provided in the middle of the restraining collar 9, and the spacer ring 12 is provided between the second locking ring 11 and the first locking ring 10;
[0027] A first turbine 6 is provided at one end of the reinforced transverse axis 5, and a second turbine 7 is provided at the other end of the reinforced transverse axis 5. The first turbine 6 is provided in the middle of the first guide chamber 2, and the second turbine 7 is provided in the middle of the second guide chamber 3.

[0028] According to the above structure, when in use, the positioning sleeve 8 is limited by the central lubricating sleeve 4, and the positioning sleeve 8 is sleeved on the outer side of the reinforced horizontal axis 5, so that when the reinforced horizontal axis 5 rotates, the positioning sleeve 8 is driven to rotate, and the positioning sleeve 8 rubs against the central lubricating sleeve 4 when rotating.
