Description

Technical Field

[0001] The present invention relates to the technical field of engine lubricating oil distribution, and in particular to a shaft oil-swinging distribution component and a shaft oil-swinging distribution device having the same. Background Art

[0002] In oil-cooled electric drive and hybrid systems, most of the components are lubricated in an active manner, which allows the lubricating oil to reach the lubricated components directly from the oil pump, and the lubricating flow rate can be adjusted by controlling the speed of the oil pump. However, if there is a lubrication demand in the shaft in the system, and there are lubrication demands for multiple components in the shaft, the distribution of the lubricating oil in the shaft changes with the speed. The higher the speed, the more oil is thrown out of the outlet closer to the oil inlet due to the influence of centrifugal force, while the outlet farther from the oil inlet has less oil or even no oil, resulting in extremely serious uneven distribution problems. The reliability of insufficiently lubricated components will deteriorate, and reliability problems such as excessive wear and ablation will easily occur.

[0003] Currently, no effective solution has been proposed for the above-mentioned technical problems. Summary of the invention

[0007] Furthermore, the fixing component also includes a second annular protrusion, which is arranged at a distance from the first annular protrusion in the radial direction of the annular base. When the fixing component is connected to the oil outlet hole, the second annular protrusion is arranged in a close fit with the side wall of the oil outlet hole, and at least a partial active cavity is formed between the second annular protrusion, the annular base, and the first annular protrusion.

[0008] Furthermore, a first limiting structure is provided at one end of the first annular protrusion away from the annular base, and the sliding assembly has an extreme position. When the sliding assembly moves to the extreme position along the axial direction of the oil outlet, the sliding assembly is cooperatively connected with the first limiting structure.

[0009] Furthermore, the first limiting structure includes a stop protrusion protruding in the radial direction of the first annular protrusion, and when the sliding assembly is in the limit position, the side of the stop protrusion facing the annular base abuts against at least part of the sliding assembly.

[0010] Further, the distance between the end of the first annular protrusion away from the annular base and the oil outlet end of the oil outlet hole is set smaller than the distance between the oil inlet end of the oil outlet hole and the oil outlet end of the oil outlet hole.

[0011] Furthermore, the sliding assembly includes a movable fitting section and an oil-blocking section, wherein the oil-blocking section is arranged near the oil inlet side of the oil outlet hole, and a second limiting structure is arranged at the connection position between the movable fitting section and the oil-blocking section. When the sliding assembly is in the extreme position, at least part of the oil-blocking section extends out of the oil outlet hole, and the second limiting structure is connected in cooperation with the first limiting structure to perform axial limiting on the sliding assembly.

[0012] Furthermore, the second limiting structure includes a limiting step, and the limiting step is arranged toward the side where the first annular protrusion is located.

[0042] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. In the accompanying drawings, for the sake of clarity, the thickness of the layers and regions may be enlarged, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0043] Combination Figures 1 to 4 As shown, according to a specific embodiment of the present application, a shaft oil-swinging distribution assembly is provided.

[0044] Specifically, Figures 1 to 4 As shown, the shaft oil-spinning distribution assembly includes a fixed assembly 20 and a sliding assembly 30. The fixed assembly 20 is used to connect with the oil outlet hole 11 of the shaft 10. When the fixed assembly 20 is connected with the oil outlet hole 11, part of the fixed assembly 20 extends into the oil outlet hole 11, and the other part of the fixed assembly 20 is arranged on the oil outlet side of the oil outlet hole 11, so that an active cavity 200 with one end closed is formed between the fixed assembly 20 and the side wall of the oil outlet hole 11, and the active cavity 200 is arranged in communication with the oil inlet side of the oil outlet hole 11; the sliding assembly 30 is arranged on the active cavity 200. The sliding component 30 is in the cavity 200, and the fixed component 20 is slidably connected along the axial direction of the oil outlet hole 11, and an adjusting oil circuit is formed between the sliding component 30 and the cavity wall of the movable cavity 200; wherein, when the oil pressure in the adjusting oil circuit reaches a preset pressure value, the oil in the adjusting oil circuit can push the sliding component 30 to move in a direction away from the oil outlet side of the oil outlet hole 11, so that at least part of the sliding component 30 extends to the oil inlet side of the oil outlet hole 11, so as to block the oil from flowing along the oil inlet side of the oil outlet hole 11 to the oil outlet side of the oil outlet hole 11.

[0045] By applying the technical solution of this embodiment, the shaft oil-swinging distribution component is fixed to the oil outlet hole 11 through the fixing component 20, and part of the fixing component 20 extends into the oil outlet hole 11 to increase the contact area between the fixing component 20 and the oil outlet hole 11, thereby improving the stability of the connection between the distribution component and the oil outlet hole 11. Another part of the fixing component 20 is arranged on the oil outlet side of the oil outlet hole 11, so that an active cavity 200 is formed between the fixing component 20 and the side wall of the oil outlet hole 11, and the active cavity 200 is connected to the oil inlet side of the oil outlet hole 11 so that the lubricating oil can enter the active cavity 200 when passing through the oil outlet hole 11, and the sliding component 30 is arranged in the active cavity 200, and the sliding component 30 and the cavity wall of the active cavity 200 form a movable cavity 200. The regulating oil circuit is regulated by the amount and pressure of the lubricating oil. As the rotation speed of the rotating shaft 10 increases, the centrifugal force on the lubricating oil increases, and the oil pressure of the lubricating oil entering the regulating oil circuit of the active chamber 200 also increases. When the lubricating oil pressure in the regulating oil circuit reaches the preset pressure for pushing the sliding component 30 to move, the oil circuit can be regulated, and the sliding component 30 is pressed to move in the direction of the oil outlet side away from the oil outlet hole 11. The sliding component 30 is pressed and extended to the lubricating oil flow end on the oil inlet side, and the lubricating oil flowing along the side wall of the oil inlet side is blocked, which can reduce the amount of lubricating oil entering the active chamber 200 along the side wall of the oil inlet side, and effectively reduce the oil output of the oil outlet hole 11 which is close to the oil inlet side.

[0046] It should be noted that the movable distance of the sliding component 30 on the cavity wall of the movable cavity 200 can be set to different movable distances according to the different distances between the oil outlet hole 11 and the oil inlet side, that is, the shaft oil-swinging distribution component can be designed to have different degrees of blocking of the lubricating oil. When the oil outlet hole 11 farther away from the oil inlet side of the shaft 10 itself has an insufficient oil output to reach the preset oil pressure of the regulating oil circuit, the oil outlet hole 11 may not be provided with a distribution component.

[0047] In this embodiment, if Figure 2 As shown, an oil drain chamber 40 is also formed on the side wall of the other end of the sliding component 30 and the fixed component 20. When the lubricating oil enters the oil outlet hole 11, it can enter the active chamber 200 and the oil drain chamber 40 at the same time. As the lubricating oil continues to enter the active chamber 200 and the oil drain chamber 40, and under the action of centrifugal force, the lubricating oil in the active chamber 200 and the oil drain chamber 40 forms a certain oil pressure. When the difference between the oil pressure acting in the active chamber 200 and the oil pressure acting in the oil drain chamber 40 reaches a value greater than the centrifugal force of the sliding component 30 itself (that is, when the preset pressure value is reached), the sliding component 30 moves and extends into the rotating shaft 10 to block the lubricating oil.

[0048] In another embodiment of the present application, a shaft oil-slinging distribution assembly is disposed on the oil outlet hole 11 of the oil pump shaft, and the distribution of the lubricating oil can be automatically adjusted according to the rotation speed of the shaft 10, thereby effectively avoiding excessive discharge of the lubricating oil during high-speed rotation, while ensuring the necessary lubricating oil output during low-speed rotation. This can be applied to various engines that require precise oil distribution, thereby improving the operating efficiency and stability of the equipment, significantly reducing mechanical wear and overheating caused by improper lubricating oil distribution, and extending the service life of the equipment.

[0049] Specifically, Figure 2 , Figure 4 As shown, the fixing assembly 20 includes an annular base 21, and one end of the annular base 21 is provided with a first annular protrusion 22 extending in the axial direction of the annular base 21. When the fixing assembly 20 is connected to the oil outlet hole 11, the first annular protrusion 22 extends into the oil outlet hole 11, and an active cavity 200 is formed between the annular base 21, the oil outlet hole 11 and the first annular protrusion 22. The first annular protrusion 22 is arranged at a distance from the side wall of the oil outlet hole 11 so that an active cavity 200 is formed between the annular base 21, the oil outlet hole 11 and the first annular protrusion 22. Such an arrangement can make the installation of the rotating shaft oil throwing distribution assembly more convenient, and also ensure the stability of the connection between the distribution assembly and the rotating shaft 10.

[0050] Furthermore, if Figure 2 , Figure 4 As shown, the fixing assembly 20 further includes a second annular protrusion 23, which is arranged at a distance from the first annular protrusion 22 along the radial direction of the annular base 21. When the fixing assembly 20 is connected to the oil outlet hole 11, the second annular protrusion 23 is arranged in close contact with the side wall of the oil outlet hole 11, and at least part of the active cavity 200 is formed between the second annular protrusion 23, the annular base 21, and the first annular protrusion 22. The second annular protrusion 23 is arranged to extend along the axial direction of the oil outlet hole 11, and the second annular protrusion 23 is arranged in close contact with the hole wall of the oil outlet hole 11, which further increases the stability and reliability of the connection between the distribution assembly and the oil outlet hole 11, and at the same time ensures the uniform distribution of the lubricating oil during high-speed rotation, effectively preventing the equipment imbalance and vibration problems caused by uneven oil distribution.

[0051] It should be noted that, in the present embodiment, the second annular protrusion 23 is connected to the side wall of the oil outlet hole 11 by an interference fit connection so that the fixing component 20 is stably connected to the oil outlet hole 11. The extension length of the second annular protrusion 23 can be adjusted according to actual needs, or the second annular protrusion 23 can be eliminated to directly connect the oil outlet hole 11 to the annular base 21.

[0052] Furthermore, a first limiting structure 24 is provided at one end of the first annular protrusion 22 away from the annular base 21, and the sliding assembly 30 has an extreme position. When the sliding assembly 30 moves to the extreme position along the axial direction of the oil outlet 11, the sliding assembly 30 is connected in a cooperative manner with the first limiting structure 24. The provision of the first limiting structure 24 limits the range of motion of the sliding assembly 30, which can effectively prevent the sliding assembly 30 from excessively moving away from the fixed assembly 20 or being damaged due to excessive oil pressure in the regulating oil circuit, that is, ensuring the safety of the operation of the distribution assembly and reducing the maintenance cost.

[0053] It should be noted that the limit position of the sliding assembly 30 is the maximum distance that the sliding assembly 30 extends axially toward the rotating shaft 10, that is, the maximum oil output that the distribution assembly can control and reduce. The limit position of the sliding assembly 30 of different distribution assemblies can be set to different positions to adapt to different setting positions of the oil outlet hole 11 on the rotating shaft 10.

[0054] Specifically, the first limiting structure 24 includes a stop protrusion 240 protruding in the radial direction of the first annular protrusion 22. When the sliding assembly 30 is in the limit position, the side of the stop protrusion 240 facing the annular base 21 abuts against at least part of the sliding assembly 30. The stop protrusion 240 limits the continued movement of the sliding assembly 30 by abutting against the sliding assembly 30, that is, the setting of the stop protrusion 240 further refines the movement control of the sliding assembly 30, thereby ensuring the reasonable distribution of the lubricating oil at different speeds and improving the performance and efficiency of the equipment.

[0055] It should be noted that the first limiting structure 24 can also be an elastic member arranged on the first annular protrusion 22 or the annular base 21, and the elastic member is connected to the sliding component 30. When the elastic member is in a natural state, the sliding component 30 is located at the initial position in the adjustment oil circuit. When the oil pressure reaches the preset pressure, the sliding component 30 can be pushed to move. The limit position of the sliding component 30 is the limit size that the elastic member can be stretched. At the same time, when the rotation speed of the rotating shaft 10 is reduced to stop, the sliding component 30 can rely on the restoring force of the elastic member to reset to the initial position, and can also achieve the effect of automatically adjusting the oil output of the oil outlet 11.

[0056] Furthermore, the distance between the end of the first annular protrusion 22 away from the annular base 21 and the oil outlet end of the oil outlet hole 11 is smaller than the distance between the oil inlet end of the oil outlet hole 11 and the oil outlet end of the oil outlet hole 11. In this way, when the lubricating oil reaches a preset pressure value in the regulating oil circuit, the sliding assembly 30 can be pushed to move more quickly, and the oil inlet amount of the oil circuit entering the oil outlet hole 11 and the oil outlet amount of the oil outlet hole 11 can be adjusted and fed back in time, thereby improving the response speed of the lubricating oil distribution in the oil outlet hole 11. It can be applied to equipment that requires rapid response, improve the operating efficiency and processing accuracy of the equipment, and enable the rotating shaft 10 to timely and accurately lubricate the corresponding components when running at high speed, avoiding the wear and precision reduction of parts caused by insufficient lubrication, and improving the operation efficiency and operation quality.

[0057] Further, the sliding assembly 30 includes a movable matching section 31 and an oil-blocking section 32, wherein the oil-blocking section 32 is arranged near the oil inlet side of the oil outlet hole 11, and a second limiting structure 33 is arranged at the connection position between the movable matching section 31 and the oil-blocking section 32. When the sliding assembly 30 is in the extreme position, at least part of the oil-blocking section 32 extends outside the oil outlet hole 11, and the second limiting structure 33 is connected in cooperation with the first limiting structure 24 to axially limit the sliding assembly 30. The provision of the second limiting structure 33 can further ensure the stability of the sliding assembly 30 in the extreme position, prevent the sliding assembly 30 from being damaged due to excessive sliding, and prevent the lubricating oil from being excessively thrown out of the oil outlet hole 11 under high-speed rotation, and the second limiting structure 33 is used in cooperation with the first limiting structure 24 to further ensure the movement accuracy of the sliding assembly 30, optimize the contact between the sliding assembly 30 and the first annular protrusion 22, and avoid the collision between the first annular protrusion 22 and the sliding assembly 30 to cause damage.

[0058] Specifically, the second limiting structure 33 includes a limiting step 330, and the limiting step 330 is arranged toward the side where the first annular protrusion 22 is located. The second limiting structure 33 is arranged such that the limiting step 330 cooperates with the stop protrusion 240 of the first limiting structure 24, which simplifies the manufacturing process of the sliding assembly 30 and the first annular protrusion 22, and reduces the manufacturing cost and time.

[0059] Furthermore, if Figure 2 As shown, a driving bevel 310 is provided at one end of the movable fitting section 31 close to the annular base 21, and the distance between the driving bevel 310 and the annular base 21 is gradually increased in the direction away from the axial center line of the annular base 21. The setting of the driving bevel 310 can increase the contact area between the lubricating oil in the regulating oil circuit and the sliding component 30, so that the oil pressure in the regulating circuit can better act on the sliding component 30, and improve the distribution efficiency of the lubricating oil.

[0060] It should be noted that the pressure and direction of the lubricating oil acting on the sliding component 30 can be adjusted by adjusting the slope of the driving ramp 310, thereby adjusting the preset oil pressure value that makes the sliding component 30 slide. For example, when the slope is 0, the driving ramp 310 is in contact with the annular base 21. In this case, no lubricating oil enters between the driving ramp 310 and the annular base 21, and it is impossible to apply pressure in the preset moving direction to the sliding component 30. Therefore, appropriately setting the slope of the driving ramp 310 can adjust the flexibility and response rate of the movement of the sliding component 30.

[0061] Furthermore, the sliding assembly 30 has an initial position. When the sliding assembly 30 is in the initial position, the end of the oil-blocking section 32 close to the oil inlet side is flush with the end of the oil outlet hole 11 close to the axial center line of the rotating shaft 10, and the end of the movable fitting section 31 close to the annular base 21 abuts against the annular base 21. When the sliding assembly 30 is in the initial position, the oil-blocking section 32 is flush with the end of the oil outlet hole 11 close to the axial center line of the rotating shaft 10, which will not affect the oil output of the oil outlet hole 11 far from the oil inlet side, so that the rotating shaft 10 can provide sufficient lubrication through the oil outlet hole 11 when rotating at a low speed, thereby preventing wear of the equipment during startup or low-speed operation.

[0062] According to another specific embodiment of the present application, a shaft oil-swinging distribution device is also provided, which includes a plurality of shaft oil-swinging distribution components. The shaft oil-swinging distribution component is the shaft oil-swinging distribution component in the above-mentioned embodiment. The distance between the initial position of the sliding component 30 and the extreme position of the sliding component 30 is the active distance of the shaft oil-swinging distribution component, and the active distances of each shaft oil-swinging distribution component are set differently.

[0063] By applying the technical solution of the present embodiment, distribution components can be set at the oil outlet holes 11 with the largest oil output close to the oil inlet side and at the oil outlet holes 11 with a larger oil output. According to the different oil outputs of the oil outlet holes 11, the movable distances of the distribution components set at the oil outlet holes 11 are also set differently, that is, the sizes of the oil discharge chambers 40 of the oil outlet holes 11 are set differently, so that the oil outputs of the oil outlet holes 11 at different distances from the oil inlet side can be evenly distributed, which can effectively solve the problem of uneven oil distribution of the oil outlet holes 11 in the rotating shaft 10 due to the centrifugal force.

[0064] The present application also provides a preferred embodiment of a shaft oil-swinging distribution assembly, which utilizes the centrifugal force of the lubricating oil to achieve the purpose of uniformly distributing the lubricating oil in the oil outlets 11 in the shaft 10 without the need for active control. It has high reliability, simple structure and low cost.

[0065] Specifically, the shaft oil-spinning and oil-distributing assembly is mainly composed of a fixed assembly 20 and a sliding assembly 30. Figures 1 to 4As shown, the oil outlet hole 11 closer to the oil inlet side is provided with a fixing component 20, and the oil outlet hole 11 needs to be expanded to facilitate the installation of the fixing component 20. The fixing component 20 and the oil outlet hole 11 are connected by interference fit to prevent the fixing component 20 from loosening or falling out due to centrifugal force. The sliding component 30 is installed on the fixing component 20. The sliding component 30 needs to use a material with low density, light weight and elastic deformation, so that the sliding component 30 can be smoothly installed on the fixing component 20 to ensure that the sliding component 30 can be pushed by the lubricating oil and overcome its own centrifugal force and the pressure of the oil discharge chamber 40 to move toward the axial direction of the rotating shaft 10.

[0066] When the lubricating oil enters the inside of the rotating shaft 10 from the oil inlet side, due to the rotation of the rotating shaft 10, the lubricating oil will flow along the inner wall of the rotating shaft 10. If the rotating shaft oil-spinning distribution component is not installed, the lubricating oil will first flow out from the oil outlet hole 11 closer to the oil inlet side, and as the rotation speed of the rotating shaft 10 increases, the amount of lubricating oil flowing out of the oil outlet hole 11 becomes larger and larger. After the rotating shaft oil-spinning distribution component is installed, the lubricating oil can flow into the active chamber 200 and the oil discharge chamber 40 of the distribution component while flowing out from the oil outlet hole 11. As the lubricating oil continues to enter the active chamber 200 and the oil discharge chamber 40 and is centrifuged, the lubricating oil will flow out of the active chamber 200 and the oil discharge chamber 40. Under the action of , a certain oil pressure is formed. When the difference between the force of the oil pressure acting on the upper end surface and the lower end surface of the sliding component 30 is greater than the centrifugal force of the sliding component 30 itself, the sliding component 30 will gradually move toward the axial direction of the rotating shaft 10. The higher the rotation speed of the rotating shaft 10, the greater the moving distance. When the sliding component 30 moves toward the axial center of the rotating shaft 10, the oil-blocking section 32 of the sliding component 30 can effectively prevent the lubricating oil from flowing out of the oil outlet 11. At this time, the lubricating oil can flow out more from other oil outlets 11, which can effectively solve the problem of uneven distribution of the oil outlets 11 in the rotating shaft 10 due to the centrifugal force.

[0067] According to another specific embodiment of the present application, an oil-cooled electric drive hybrid system is also provided. The oil-cooled electric drive and hybrid system includes a shaft oil-swinging distribution component. The shaft oil-swinging distribution component includes a fixed component 20 and a sliding component 30. The fixed component 20 is used to connect with the oil outlet hole 11 of the shaft 10.
