Description

Technical Field

[0001] This utility model belongs to the technical field of turbocharger rotor shafts, specifically relating to a fracture-resistant and highly stable turbocharger rotor shaft. Background Technology

[0002] Currently, to prevent the magnets from breaking during high-speed rotation of the turbocharger rotor shaft, most methods involve installing a protective cover around the magnets to prevent them from breaking due to displacement or collision. For example, an electric turbocharger rotor shaft disclosed in Chinese Patent Publication No. CN221973636U. However, after the magnets are wrapped in the protective cover, the heat of the magnets cannot be dissipated quickly, which often leads to cracks in the magnets due to high temperature during high-speed rotation of the turbocharger rotor shaft. Utility Model Content

[0003] The purpose of this invention is to provide a shatterproof, highly stable turbocharger rotor shaft, which solves the problem that when the magnets of existing turbocharger rotor shafts are encased in a protective cover to prevent breakage, the heat of the magnets cannot be dissipated quickly, leading to cracks in the magnets due to high temperatures during high-speed rotation of the turbocharger rotor shaft.

[0004] The specific technical solution adopted by this utility model is as follows:

[0005] A shatterproof, high-stability turbocharger rotor shaft includes a hollow shaft. A left and right shaft body are fixedly connected to the inner wall of the hollow shaft. Magnets are fixedly connected to the surface of the hollow shaft, and a protective cover is fitted onto the surface of the magnets. Fan blades are fixedly connected to the surface of the hollow shaft. An air outlet and an air inlet are provided inside the hollow shaft. A through hole is also provided inside the hollow shaft. A heat sink is fixedly connected to the inner wall of the hollow shaft. Heat-conducting plates are fixedly connected to the surface of the heat sink, the inner wall of the through hole, and the inner wall of the magnets. Heat dissipation grooves are provided on the inner wall of the heat sink.

[0006] The present invention is further configured such that the protective cover includes a cylinder, a left guard plate, a right guard plate, and a conical cylinder; the left and right sides of the magnet are respectively fixedly connected to the right side of the left guard plate and the left side of the right guard plate; the inner walls of the left guard plate and the right guard plate are both fixedly connected to the surface of the hollow shaft; the surfaces of the left guard plate and the right guard plate are both fixedly connected to the inner wall of the cylinder; the inner wall of the cylinder is in contact with the surface of the magnet; the inner wall of the cylinder is fixedly connected to the surface of the conical cylinder; the left side of the conical cylinder is fixedly connected to the right side of the right guard plate; and the fan blade is located inside the cylinder and on the right side of the conical cylinder.

[0007] The present invention is further configured such that the air outlet is located on the right side of the heat sink, and the right shaft and fan blade are both located on the right side of the air outlet.

[0008] The present invention is further configured such that the air inlet is located on the left side of the heat sink, and the left shaft is located on the left side of the air inlet.

[0009] The present invention is further configured such that a circular filter screen is attached to both the right side of the cylinder and the surface of the hollow shaft, a first rubber sleeve is adhered to the surface of the circular filter screen, the inner wall of the first rubber sleeve is attached to the surface of the cylinder, and a first clamp is provided on the surface of the first rubber sleeve; a second rubber sleeve is adhered to the right side of the circular filter screen, the inner wall of the second rubber sleeve is attached to the surface of the hollow shaft, and a second clamp is provided on the surface of the second rubber sleeve.

[0010] The present invention is further configured such that a cylindrical filter screen is sleeved on the surface of the hollow shaft, and a ring is fixedly connected to the right side of the left guard plate and the surface of the hollow shaft. The left side of the ring is attached to the right side of the cylindrical filter screen, and a third rubber sleeve is adhered to the surface of the cylindrical filter screen. The inner wall of the third rubber sleeve is attached to the surface of the ring, and a third clamp is provided on the surface of the third rubber sleeve.

[0011] The technical effects achieved by this utility model are as follows:

[0012] The shatterproof, high-stability turbocharger rotor shaft of this invention, through the combination of a cylinder, a conical cylinder, fan blades, an air inlet, and an air outlet, generates a high-speed airflow inside the hollow shaft when the turbocharger rotor shaft rotates. This high-speed airflow allows the heat from the heat sink to dissipate quickly. At this time, the heat sink can continuously and efficiently absorb the heat from the magnets, thus preventing the magnets from becoming too hot and avoiding cracks caused by excessive temperature.

[0013] This utility model's shatterproof, high-stability turbocharger rotor shaft, through the cooperation of a circular filter and a cylindrical filter, can prevent dust in the air from entering the hollow shaft, thereby preventing the heat dissipation efficiency of the heat sink from being reduced due to dust adhering to it. At the same time, through the cooperation of a first rubber sleeve, a first clamp, a second rubber sleeve, a second clamp, a ring, a third rubber sleeve, and a third clamp, the circular and cylindrical filters are made easier to disassemble and assemble, thus facilitating cleaning of the circular and cylindrical filters by maintenance personnel.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] like Figures 1 to 8As shown, the shatterproof, high-stability turbocharger rotor shaft includes a hollow shaft 1. A left shaft body 2 and a right shaft body 3 are fixedly connected to the inner wall of the hollow shaft 1. A magnet 4 is fixedly connected to the surface of the hollow shaft 1. A protective cover 5 is attached to the surface of the magnet 4. A fan blade 6 is fixedly connected to the surface of the hollow shaft 1. An air outlet 7 and an air inlet 8 are opened inside the hollow shaft 1. A through hole 9 is opened inside the hollow shaft 1. A heat sink 10 is fixedly connected to the inner wall of the hollow shaft 1. A heat-conducting plate 11 is fixedly connected to the surface of the heat sink 10, the inner wall of the through hole 9, and the inner wall of the magnet 4. A heat dissipation groove 12 is opened on the inner wall of the heat sink 10.

[0029] The protective cover 5 includes a cylinder 51, a left guard plate 52, a right guard plate 53, and a conical cylinder 54. The left and right sides of the magnet 4 are fixedly connected to the right side of the left guard plate 52 and the left side of the right guard plate 53, respectively. The inner walls of the left guard plate 52 and the right guard plate 53 are fixedly connected to the surface of the hollow shaft 1. The surfaces of the left guard plate 52 and the right guard plate 53 are fixedly connected to the inner wall of the cylinder 51. The inner wall of the cylinder 51 is in contact with the surface of the magnet 4. The inner wall of the cylinder 51 is fixedly connected to the surface of the conical cylinder 54. The left side of the conical cylinder 54 is fixedly connected to the right side of the right guard plate 53. The fan blade 6 is located inside the cylinder 51 and is located on the right side of the conical cylinder 54.

[0030] The air outlet 7 is located on the right side of the heat sink 10, the right shaft 3 and the fan blade 6 are both located on the right side of the air outlet 7, the air inlet 8 is located on the left side of the heat sink 10, and the left shaft 2 is located on the left side of the air inlet 8.

[0031] It should be noted that the magnet 4 is protected by the cylinder 51, the left guard plate 52 and the right guard plate 53 to prevent the magnet 4 from breaking due to displacement or collision when rotating. At the same time, when the fan blade 6 rotates, the air outside the hollow shaft 1 enters the hollow shaft 1 through the air inlet 8 through the fan blade 6, the cylinder 51 and the conical cylinder 54, and the air inside the hollow shaft 1 is discharged through the air outlet 7. At this time, a high-speed airflow is generated in the hollow shaft 1, and the heat of the heat sink 10 can be quickly dissipated through the high-speed airflow. The heat of the magnet 4 can be transferred to the heat sink 10 through the heat conduction plate 11. Both the heat sink 10 and the heat conduction plate 11 are made of aluminum alloy with high thermal conductivity. By setting heat dissipation grooves 12 on the inner wall of the heat sink 10, the contact surface between the heat sink 10 and the air can be effectively increased.

[0032] like Figures 1 to 10 As shown, a circular filter screen 13 is attached to the right side of the cylinder 51 and the surface of the hollow shaft 1. A first rubber sleeve 14 is bonded to the surface of the circular filter screen 13. The inner wall of the first rubber sleeve 14 is attached to the surface of the cylinder 51. A first clamp 15 is provided on the surface of the first rubber sleeve 14. A second rubber sleeve 16 is bonded to the right side of the circular filter screen 13. The inner wall of the second rubber sleeve 16 is attached to the surface of the hollow shaft 1. A second clamp 17 is provided on the surface of the second rubber sleeve 16.

[0033] A cylindrical filter screen 18 is fitted onto the surface of the hollow shaft 1. A ring 19 is fixedly connected to the right side of the left guard plate 52 and the surface of the hollow shaft 1. The left side of the ring 19 is attached to the right side of the cylindrical filter screen 18. A third rubber sleeve 20 is bonded to the surface of the cylindrical filter screen 18. The inner wall of the third rubber sleeve 20 is attached to the surface of the ring 19. A third clamp 21 is provided on the surface of the third rubber sleeve 20.

[0034] It should be noted that the first rubber sleeve 14 can be fixed to the cylinder 51 by the first clamp 15, and the second rubber sleeve 16 can be fixed to the hollow shaft 1 by the second clamp 17. When the circular filter screen 13 is fixed to the right side of the cylinder 51, the circular filter screen 13 can effectively prevent dust in the air from entering the hollow shaft 1 through the air outlet 7. The cooperation of the first rubber sleeve 14, the first clamp 15, the second rubber sleeve 16, and the second clamp 17 makes it easy to install and remove the circular filter screen 13. The third clamp 21... The third rubber sleeve 20 can be fixed on the ring 19. After the third rubber sleeve 20 is fixed on the ring 19, the cylindrical filter screen 18 is fixed at the air inlet 8. The cylindrical filter screen 18 prevents dust in the air from entering the hollow shaft 1 through the air inlet 8. At the same time, the combination of the ring 19, the third rubber sleeve 20 and the third clamp 21 makes it easier to assemble and disassemble the cylindrical filter screen 18. Both the circular filter screen 13 and the cylindrical filter screen 18 are stainless steel filter screens, and both the circular filter screen 13 and the cylindrical filter screen 18 have a mesh count of 100 mesh.

[0035] The working principle of this utility model is as follows: the cylinder 51, the left guard plate 52 and the right guard plate 53 protect the magnet 4 to prevent it from breaking due to displacement or collision when rotating. When the turbocharger rotor shaft rotates, the air outside the hollow shaft 1 enters the hollow shaft 1 through the air inlet 8 through the fan blade 6, the cylinder 51 and the conical cylinder 54. The air inside the hollow shaft 1 is discharged through the air outlet 7, and a high-speed airflow is generated inside the hollow shaft 1. At this time, the heat of the heat sink 10 can be quickly dissipated through the high-speed airflow. Through the heat conduction plate 11 and the heat sink 10, the heat sink 10 can continuously and efficiently absorb the heat of the magnet 4, so that the temperature of the magnet 4 will not be too high, thereby avoiding cracks caused by excessive temperature.

[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
