[0037] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0038] Reference below Figure 1-Figure 3 A mounting structure 100 according to an embodiment of the first aspect of the present invention will be described.

[0039] The mounting structure 100 according to the first embodiment of the present invention is used to mount an oil-gas separator 200. Figure 1 and Figure 2 As shown, the oil-gas separator 200 has an oil outlet 210 , and the mounting structure 100 includes: a support plate 10 , a mounting portion 20 and a flow guide 30 .

[0040] Specifically, a plurality of through holes 11 are formed on the support plate 10 and pass through the support plate 10 along the thickness direction of the support plate 10. The mounting portion 20 is provided on the support plate 10. The mounting portion 20 is used to install the oil-gas separator 200. The guide member 30 is connected to the support plate 10. The guide member 30 is formed with a guide surface. The guide surface is arranged on the lower side of the oil outlet 210 and is opposite to the oil outlet 210 up and down. The guide surface is configured to guide the oil flowing out of the oil outlet 210 to the through hole 11.

[0041] Among them, the oil-gas separator 200 and the mounting structure 100 are arranged in the oil tank. The oil-gas separator 200 separates the oil and gas discharged from the oil tank. The periphery of the support plate 10 is connected to the inner wall of the oil tank. The oil-gas separator 200 is installed on the support plate 10 through the mounting part 20.

[0042] It is understandable that the gas in the oil tank will contain a portion of lubricating oil vapor. When the oil tank is vented, the lubricating oil mixed gas enters the oil-gas separator 200. The oil-gas separator 200 separates the lubricating oil from the mixed gas, and then discharges the separated gas to the exhaust port of the oil tank, and discharges the separated lubricating oil from the oil outlet 210. The lubricating oil discharged from the oil outlet 210 will drip onto the guide member 30, and the lubricating oil flows along the guide surface to the support plate 10 and drips into the oil tank from the through hole 11 on the support plate 10.

[0043] Compared with the lubricating oil level in the oil tank, the distance between the guide member 30 and the oil outlet 210 is shorter. In this way, the speed of the lubricating oil from the oil outlet 210 when dripping onto the guide member 30 is lower. In the process of the lubricating oil flowing along the guide surface, the guide surface can slow down the lubricating oil, and after the lubricating oil flows along the guide surface to the support plate 10, the support plate 10 can further reduce the speed of the lubricating oil. As a result, the lubricating oil flowing out of the oil outlet 210 can be made to drip onto the lubricating oil level in the oil tank at a slower speed. On the one hand, the noise generated by the collision of lubricating oil droplets is less, which can improve the quiet performance of the lubrication system. On the other hand, the probability of bubbles generated by the collision of lubricating oil droplets is lower, and when bubbles are generated, the bubbles are also smaller, thereby improving the oil-gas separation effect in the oil tank.

[0044] According to the installation structure 100 of the embodiment of the first aspect of the present invention, the speed at which the lubricating oil flowing out of the oil outlet 210 contacts the lubricating oil liquid surface in the oil tank can be reduced, thereby improving the quietness performance of the lubrication system and improving the oil-gas separation effect in the oil tank.

[0045] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the guide member 30 is cylindrical, with at least a portion of its outer circumference forming a guide surface. The cross-sectional dimensions of at least a portion of the guide member 30 gradually increase from top to bottom. In other words, the cross-sectional dimensions of the guide member 30 can gradually increase from top to bottom, either partially or as a whole. This enhances the deceleration effect of the guide member 30 on the lubricating oil. Furthermore, when the lubricating oil drips onto the inclined guide surface, the impact noise is reduced, further enhancing the quietness of the lubrication system.

[0046] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the flow guide 30 includes a constant diameter section 31 and a variable diameter section 32. The variable diameter section 32 is connected to the end of the constant diameter section 31 facing the support plate 10. From top to bottom, the outer diameter of the constant diameter section 31 remains constant, while the outer diameter of the variable diameter section 32 gradually increases. This allows the cross-sectional dimensions of at least a portion of the flow guide 30 to gradually increase from top to bottom. During product design, the dimensions of the constant diameter section 31 and the variable diameter section 32 can be adjusted to meet various product design requirements.

[0047] In some embodiments of the present invention, Figure 1 and Figure 3As shown, from top to bottom, the outer wall of the reducing section 32 extends along the radially inwardly recessed arc line of the flow guide 30. This reduces the angle between the flow direction of the lubricating oil and the support plate 10 as it flows from the flow guide surface to the support plate 10, further improving the quietness of the lubrication system. Furthermore, compared to a straight line, the arc line is longer, which increases the flow time of the lubricating oil in the reducing section 32, further enhancing the deceleration effect of the flow guide 30 on the lubricating oil.

[0048] In some embodiments of the present invention, Figure 3 As shown, the radius R of the arc line is greater than or equal to 5 mm and less than or equal to 15 mm. For example, the radius R of the arc line can be 5 mm, 6 mm, 8 mm, 10 mm, 13 mm, or 15 mm. In this way, the deceleration effect of the guide surface on the lubricating oil can meet the needs of use. During the product design process, the radius R of the arc line can be adjusted to meet more product design needs.

[0049] In some embodiments of the present invention, Figure 2 As shown, the ratio of the maximum outer diameter D of the flow guide member 30 to the inner diameter of the oil outlet 210 is greater than or equal to 1.5 and less than or equal to 2.5. For example, the ratio of the maximum outer diameter D of the flow guide member 30 to the inner diameter of the oil outlet 210 can be 1.5, 1.7, 2.0, 2.3, or 2.5. This allows the flow guide surface to achieve the desired deceleration effect on the lubricating oil. During product design, the ratio of the maximum outer diameter D of the flow guide member 30 to the inner diameter of the oil outlet 210 can be adjusted to meet various product design requirements.

[0050] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the mounting portion 20 is formed as a supporting boss, the lower end of which is connected to the support plate 10, and the upper end of which is adapted to support the oil-gas separator 200. When assembled, the upper end of the supporting boss is connected to the oil-gas separator 200, thereby supporting and limiting the oil-gas separator 200. The relatively simple structure of the supporting boss reduces production complexity, and the size and shape of the supporting boss can be adjusted during product design to meet a variety of product design requirements.

[0051] In some embodiments of the present invention, the height of the flow guide 30 protruding from the support plate 10 is less than the height of the supporting boss protruding from the support plate 10. This allows sufficient space below the oil-gas separator 200 for arranging the flow guide 30, and when the oil-gas separator 200 is provided with a positioning tube 250, there is sufficient space for the flow guide 30 to extend into the positioning tube 250.

[0052] In some embodiments of the present invention, Figure 2As shown, there are multiple supporting bosses, for example, two, three or four supporting bosses, which are arranged around the guide member 30. Thus, the stability and reliability of the supporting bosses supporting the oil-gas separator 200 can be improved.

[0053] In some embodiments of the present invention, the supporting boss is snap-connected to the oil-gas separator 200. The snap-connection operation is convenient, which can reduce the difficulty in the production process and improve production efficiency.

[0054] Reference below Figure 1-Figure 3 An oil-gas separation device 1000 according to an embodiment of the second aspect of the present invention will be described.

[0055] According to the oil-gas separation device 1000 of the second embodiment of the present invention, Figure 1 As shown, it includes: the mounting structure 100 and the oil-gas separator 200 according to the embodiment of the first aspect of the present invention.

[0056] Specifically, the oil-gas separator 200 has an oil outlet 210 . The oil-gas separator 200 is connected to the mounting portion 20 . The flow guide 30 is vertically opposite to the oil outlet 210 .

[0057] During the operation of the oil-gas separator 200, the oil-gas separator 200 separates the lubricating oil mixed gas entering therein, and the separated lubricating oil flows out of the oil-gas separator 200 from the oil outlet 210. The guide member 30 and the support plate 10 can slow down the lubricating oil, so that when the lubricating oil drips to the lubricating oil liquid level in the oil tank, the speed of the lubricating oil is slower.

[0058] The oil-gas separation device 1000 according to the second embodiment of the present invention can improve the quietness performance of the lubrication system and the oil-gas separation effect in the oil tank by providing the mounting structure 100 according to the first embodiment of the present invention.

[0059] In some embodiments of the present invention, Figure 1 As shown, the oil-gas separator 200 further includes an oil outlet pipe 240, an oil outlet port 210 formed at the lower end of the oil outlet pipe 240, and a positioning pipe 250 disposed within the oil outlet pipe 240. The peripheral wall of the positioning pipe 250 is connected to the inner wall of the oil outlet pipe 240, and the flow guide 30 extends into the positioning pipe 250. The positioning pipe 250 allows the flow guide 30 and the positioning pipe 250 to cooperate during production, allowing the oil-gas separator 200 to be quickly positioned on the mounting structure 100, thereby reducing production complexity and improving assembly accuracy.

[0060] Among them, preferably, the inner wall of the positioning tube 250 is provided with a plurality of positioning plates 260 arranged at intervals along the circumference of the positioning tube 250, and the flow guide member 30 is provided between the plurality of positioning plates 260. Thus, the material of the positioning tube 250 can be saved. During the product design process, the size of the positioning plate 260 can be adjusted to adjust the size of the accommodating space in the positioning tube 250, thereby reducing the difficulty of product design.

[0061] In some embodiments of the present invention, Figure 1 As shown, the oil-gas separator 200 further includes an air inlet pipe 220, with an air inlet port 230 formed at the lower end of the air inlet pipe 220. The support plate 10 also includes a through-hole 12 extending through the thickness of the support plate 10, and the air inlet pipe 220 is disposed in the through-hole 12. Thus, the inner wall of the through-hole 12 can limit the displacement of the air inlet pipe 220, thereby further improving the stability of the oil-gas separator 200 on the mounting structure 100.

[0062] The lubrication system according to the embodiment of the third aspect of the present invention includes: an oil tank and the oil-gas separation device 1000 according to the embodiment of the second aspect of the present invention.

[0063] Specifically, the oil tank is used to contain lubricating oil, and the oil tank has an exhaust port. The oil-gas separation device 1000 is disposed in the oil tank. The oil-gas separator 200 has an air inlet 230 and an air outlet, and the air outlet is connected to the exhaust port.

[0064] Among them, by separately providing an oil tank for containing lubricating oil in the lubricating system, the flow of lubricating oil in the lubricating system is more stable and the cooling effect of the lubricating oil is better, thereby improving the lubricating effect of the lubricating system.

[0065] When the oil tank is vented, the lubricating oil mixed gas enters the oil-gas separator 200 from the air inlet 230. The oil-gas separator 200 separates the lubricating oil from the mixed gas, and then discharges the separated gas from the air outlet to the exhaust port of the oil tank. At the same time, the separated lubricating oil is discharged from the oil outlet 210. The lubricating oil discharged from the oil outlet 210 will drip onto the guide member 30, flow along the guide surface to the support plate 10, and drip into the oil tank from the through hole 11 on the support plate 10.

[0066] According to the lubrication system of the third embodiment of the present invention, by providing the oil-gas separation device 1000 according to the second embodiment of the present invention, the quietness performance of the lubrication system and the oil-gas separation effect in the oil tank can be improved.
