[0002] The Roots blower belongs to the positive displacement blower. It drives the main impeller to rotate through a driving device, and the main impeller synchronously drives the driven impeller to rotate in the opposite direction through gear meshing, thereby realizing the transportation of gas. The gears meshing in the oil tank will generate a relatively high temperature. The gear oil tray structure can play a certain role in cooling the lubricating oil in the oil tank. However, the traditional gear oil tray structure has problems such as inconvenient installation and disassembly of gears and inability to be compatible with both vertical and horizontal blowers at the same time. Summary of the Invention

The gear oil tray oil pool is formed by fixedly connecting a rear connecting plate, a right bottom plate, a left bottom plate, a support plate, a front connecting plate, and an oil baffle. It can meet the vertical and horizontal installation and use of Roots blowers at the same time, has strong versatility, and the oil baffle can be disassembled separately, which facilitates the installation and disassembly of gears.

[0004] Therefore, the technical solution of the present invention is a gear oil tray structure that is applicable to both vertical and horizontal installations, including a rear connecting plate, a right bottom plate, a left bottom plate, a support plate, a front connecting plate, and an oil baffle.

[0025] The following further describes the present invention in conjunction with embodiments.

[0026] Figures 1-7 This is an embodiment of a gear oil tray structure that is universal for vertical and horizontal use in the present invention, which includes a rear connecting plate 1, a right bottom plate 2, a left bottom plate 3, a support plate 4, a front connecting plate 5 and an oil baffle 6. The rear connecting plate 1, the right bottom plate 2, the left bottom plate 3, the support plate 4 and the front connecting plate 5 are fixed by welding. The oil baffle 6 is connected and fixed to the front connecting plate 5 through a connecting bolt 7, a spring washer 8 and a nut 9. The right end of the rear connecting plate 1 is provided with a first arc hole 101 of the rear connecting plate, the left end of the rear connecting plate 1 is provided with a second arc hole 102 of the rear connecting plate, and a fixing hole 301 of the rear connecting plate is provided below the first arc hole 101 and the second arc hole 102 of the rear connecting plate. The rear connecting plate 1 is fixedly connected to the wall panel 12 of the Roots blower through the fixing hole 301 of the rear connecting plate and a fixing bolt 10.

[0027] The shape of the right bottom plate 2 is arc-shaped. The middle of the right half of the right bottom plate 2 is provided with a vertical oil inlet hole 201 of the right plate, and the middle of the left half of the right bottom plate 2 is provided with a horizontal oil inlet hole 202 of the right plate. The shape of the left bottom plate 3 is arc-shaped, and the middle of the left bottom plate 3 is provided with an oil inlet hole of the left plate. The support plate 4 is located between the right bottom plate 2 and the left bottom plate 3, and an oil return hole 11 is provided between the support plate 4 and the rear connecting plate 1, the right bottom plate 2 and the left bottom plate 3.

[0028] In a specific embodiment, the height of the support plate 4 is lower than the upper edges of the right bottom plate 2 and the left bottom plate 3. The support plate 4 and the rear connecting plate 1, the right bottom plate 2, the left bottom plate 3 and the front connecting plate 5 enclose an oil sump, and the oil return hole 11 is located on one side of the oil sump.

[0029] The right end of the front connecting plate 5 is provided with a first circular arc hole 501 of the front connecting plate, the left end of the front connecting plate 5 is provided with a second circular arc hole 502 of the front connecting plate, and a fixing hole 503 of the front connecting plate is provided below the first circular arc hole 501 and the second circular arc hole 502 of the front connecting plate.

[0030] The right end of the oil baffle 6 is provided with a vertical oil baffle edge line 601, the left end of the oil baffle 6 is provided with a horizontal oil baffle edge line 602, and a fixing hole 603 of the oil baffle is provided below the vertical oil baffle edge line 601 and the horizontal oil baffle edge line 602.

[0031] In a specific embodiment, the circular arc radii of the first circular arc hole 101 and the second circular arc hole 102 of the rear connecting plate are the same, and the circular arc radii of the first circular arc hole 101 and the second circular arc hole 102 of the rear connecting plate are larger than the outer circle radius of the bearing of the Roots blower. The radian of the circular arc of the first circular arc hole 101 of the rear connecting plate is 180±5 degrees, and the radian of the circular arc of the second circular arc hole 102 of the rear connecting plate is 90±5 degrees. If the radian of the first circular arc hole 101 and the second circular arc hole 102 of the rear connecting plate is too large, oil slinging will affect the oil slinging effect and is not conducive to oil slinging; if the radian is too small, too little is wrapped and the separation of internal and external lubricating oil cannot be achieved, which is not conducive to the circulating cooling of the lubricating oil.

[0032] In a specific embodiment, the circular arc radii of the right bottom plate 2 and the left bottom plate 3 are the same, and the circular arc radii of the right bottom plate 2 and the left bottom plate 3 are larger than the outer circle radius of the gear 13 of the Roots blower. The radian of the circular arc of the right bottom plate 2 is 180±5 degrees, and the radian of the circular arc of the left bottom plate 3 is 90±5 degrees; the circular arc radii of the first circular arc hole 501 and the second circular arc hole 502 of the front connecting plate are the same, and the circular arc radii of the first circular arc hole 501 and the second circular arc hole 502 of the front connecting plate are larger than the outer circle radius of the gear 13 of the Roots blower.

[0033] The vertical and horizontal universal gear oil tray structure is formed by fixedly connecting the rear connecting plate 1, the right bottom plate 2, the left bottom plate 3, the support plate 4, the front connecting plate 5 and the oil baffle 6 to enclose an oil sump of the gear oil tray. When used horizontally, the oil level line of the lubricating oil is determined by the height of the horizontal oil baffle edge line 602. The oil level line is lower than the upper edges of the right bottom plate 2 and the left bottom plate 3 and higher than the heights of the horizontal oil inlet hole 202 of the right plate and the oil inlet hole 301 of the left plate. The lubricating oil directly downward after gear meshing flows back to the fuel tank through the oil return hole 11, avoiding the hot lubricating oil after meshing from entering the inner oil sump of the gear oil tray. When used vertically, the oil level line of the lubricating oil is determined by the height of the vertical oil baffle edge line 601, and the oil level line is higher than the height of the vertical oil inlet hole 201 of the right plate.

[0034] When the Roots blower is working, the synchronous gears move in opposite directions, driving the lubricating oil in the oil sump of the gear oil tray structure to splash, achieving the lubrication of the bearings and gears. The hot lubricating oil after lubrication returns to the upper surface inside the oil tank, and the cold lubricating oil enters the oil sump of the oil tray through the oil inlet hole of the lubricating oil. In this way, the circulation of hot and cold lubricating oil is realized inside the oil tank, achieving the purpose of reducing the temperature of the lubricating oil in the oil tank.

[0035] This vertical and horizontal universal gear oil tray structure can meet the vertical and horizontal installation and use of the Roots blower at the same time, with strong versatility; the oil baffle can be disassembled separately, facilitating the installation and disassembly of the gears; this gear oil tray structure is conducive to the decrease in the temperature of the lubricating oil in the oil tank, and can reduce the temperature of the lubricating oil in the oil tank by 3 - 5 °C.

[0036] Only as described above are specific embodiments of the present invention. However, the scope of implementation of the present invention cannot be limited thereby. Therefore, the replacement of equivalent components or equivalent changes and modifications made according to the scope of protection of the present invention patent shall still fall within the scope covered by the claims of the present invention.
