Description

Technical Field

[0001] This utility model relates to the field of engine vacuum pump installation technology, and in particular to an engine direct drive vacuum pump assembly. Background Technology

[0002] An engine-driven vacuum pump assembly is a high-efficiency, compact vacuum pump system that directly transmits engine power to the vacuum pump, thus avoiding energy loss in traditional transmission methods. An engine-driven vacuum pump assembly refers to a system where the vacuum pump is directly mounted on the engine, and the engine's power is transmitted to the vacuum pump through some transmission method. Currently, engine-driven vacuum pump assemblies generally connect the engine and vacuum pump shafts directly via a coupling. However, a direct connection, if the shafts are not aligned, may cause additional wear and vibration due to misalignment. While a coupling can compensate for shaft misalignment caused by manufacturing or installation errors between the engine and vacuum pump, if the clearance between the engine and vacuum pump output shafts is too large, or if the shaft misalignment is too significant, the coupling cannot be easily modified to accommodate such situations, thus affecting the connection between the engine and vacuum pump.

An L-shaped rod is connected to one side of the mounting plate, and an L-shaped tube is slidably connected to the surface of the L-shaped rod. A sleeve is slidably connected to one end of the L-shaped tube.

[0006] The surface of the L-shaped tube is provided with a movable groove, and a connecting ring is threaded onto the surface of the L-shaped tube. A connecting rod connected to the L-shaped rod is also connected inside the connecting ring.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-4 The engine direct-drive vacuum pump assembly includes a connecting shaft mounted on the surfaces of the engine body 1 and the vacuum pump body 2. A mounting base 3 is connected to the surface of the connecting shaft, and a mounting plate 4 is connected to one side of the mounting base 3. An L-shaped rod 5 is connected to one side of the mounting plate 4, and an L-shaped tube 6 is slidably connected to the surface of the L-shaped rod 5. A sleeve 7 is slidably connected to one end of the L-shaped tube 6. A movable groove 8 is formed on the surface of the L-shaped tube 6, and a connecting ring 9 is threaded onto the surface of the L-shaped tube 6. A connecting rod 10 connected to the L-shaped rod 5 is connected inside the connecting ring 9. By rotating the connecting ring 9, it can rotate and move, thereby driving the L-shaped rod 5, the mounting plate 4, and the mounting base 3 to move via the connecting rod 10. This can be adjusted according to the deviation between the engine and vacuum pump shafts for easy installation and use.

[0025] Furthermore, the connecting rod 10 is movably connected to the interior of the moving groove 8, which allows the connecting ring 9 to rotate and move, thereby driving the connecting rod 10 to move inside the moving groove 8.

[0026] Furthermore, the inner wall of the connecting ring 9 is provided with a groove 11, and a slider 12 connected to the connecting rod 10 is slidably connected inside the groove 11. This is to facilitate the connecting ring 9 to rotate and move on the surface of the L-shaped tube 6, so that the connecting ring 9 can rotate on the surface of the connecting rod 10 through the slider 12 and the groove 11. At the same time, the connecting rod 10 can also be driven to move inside the moving groove 8 through the slider 12 and the groove 11.

[0027] Furthermore, a screw 13 is connected to the surface of the L-shaped tube 6, and a connecting tube 14 is threaded to one end of the screw 13. A fixing rod 15 is connected to the surface of the sleeve 7, and a bearing 16 connected to the connecting tube 14 is connected to one end of the fixing rod 15. By rotating the connecting tube 14, the screws 13 on both sides inside the sleeve 7 can drive the L-shaped tube 6 to move within the sleeve 7, thereby allowing the L-shaped tube 6 to drive the L-shaped rod 5, the mounting plate 4, and the mounting base 3 to be adjusted according to the gap between the engine and the vacuum pump shaft.

[0028] Furthermore, the threads on both sides of the inside of the connecting pipe 14 are arranged in opposite directions, which is to facilitate the simultaneous movement of the screws 13 connected by the threads on both sides of the inside of the connecting pipe 14 in opposite directions or in opposite directions when the connecting pipe 14 rotates.
