Description

Technical Field

[0001] This utility model relates to the field of lubricating oil pump technology, and in particular to a lubricating oil pump for a gearbox. Background Technology

[0002] In modern industry, gearboxes are widely used in various mechanical equipment, and their stable operation is crucial to the overall performance of the equipment. The gearbox lubrication pump, as a key component ensuring the normal operation of the gearbox, is responsible for delivering lubricating oil to all critical parts of the gearbox, playing a role in lubrication, cooling, and cleaning. This ensures that gears, bearings, and other components within the gearbox operate under optimal conditions, reducing wear and extending the equipment's service life.

[0003] Currently, some transmission lubricating oil pumps use welding to fix the pump to the filter plate in their filter plate connection design. This connection method has revealed many problems in actual use. Welding makes the filter plate and the lubricating oil pump an inseparable whole. When the filter plate needs cleaning due to accumulated impurities from long-term use or needs to be replaced due to damage, it is impossible to operate the filter plate directly. To maintain or replace the filter plate, the entire lubricating oil pump must be removed from the equipment. This is not only cumbersome, but also prone to damaging other components of the lubricating oil pump during removal and handling. Furthermore, the entire maintenance process is time-consuming, leading to prolonged equipment downtime and severely impacting production efficiency. To address this technical problem, this application proposes a transmission lubricating oil pump. Utility Model Content

[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1-3 An embodiment of this utility model provides a gearbox lubricating oil pump, including a housing 1. The top of the housing 1 is connected to a top cover 4 via a magnet 1 2 and a magnet 2 3. A sound insulation pad 9 is fixedly connected to the inner wall of the housing 1. A pump body 6 is fixedly connected to the inner wall of the housing 1. A drive shaft 7 is provided at the left end of the pump body 6. An oil inlet pipe 10 is fixedly connected to the right end of the pump body 6. A fixing ring 11 is fixedly connected to the outer wall of the oil inlet pipe 10. A fixing ring 22 is provided at the right end of the fixing ring 11. An oil inlet pipe 23 is fixedly connected to the inner wall of the fixing ring 22. A retaining ring 12 is provided on the outer wall of both the fixing ring 11 and the fixing ring 22. A retaining ring 24 is rotatably connected to the bottom end of the retaining ring 12. The front end of the retaining ring 12 is connected to the retaining ring 24 via a limiting block 13, a limiting block 25, a nut 16, a screw 17, a butterfly plate 18, and a washer 19. A filter plate 20 is provided at the near end of the fixing ring 11 and the fixing ring 22.

[0026] Specifically, the groove on the top cover 4 is accurately fitted onto the oil outlet pipe 8 at the top of the pump body 6. Then, the positioning tenon 5 at the bottom of the top cover 4 is aligned with the corresponding groove on the housing 1 and inserted. When the top cover 4 moves to the appropriate position, the magnet 2 at the top of the housing 1 and the magnet 3 at the bottom of the top cover 4 will have a magnetic attraction. This magnetic attraction can effectively limit the position of the top cover 4 and ensure that the top cover 4 is installed firmly. The sound insulation pad 9 has several honeycomb grooves, which can absorb the noise generated by the pump body 6 during operation, reduce the noise of the lubricating oil pump during operation, and reduce the impact of noise on the surrounding environment. The noise generated by the pump body 6 during operation can be reduced through the housing 1, the top cover 4, and the sound insulation pad 9. When the filter plate 20 needs maintenance and replacement, first pull the top cover 4 upward to pull the positioning tenon 5 out of the housing 1. At this time, the pump body 6 will be exposed. Then, pinch the butterfly plate 18 and rotate it. The butterfly plate 18 will drive the screw 17 to rotate together. Since the screw 17 and the nut 16 are threadedly connected, the rotation of the screw 17 will increase the distance between the washer 19 and the nut 16. Then rotate the nut 16 to make the screw 17 disengage from the groove of the limiting block 13. In this way, the retaining ring 12 and retaining ring 24 can be removed from the fixing ring 11 and fixing ring 22, and then the filter plate 20 can be removed from the fixing ring 11 and fixing ring 22.

[0027] Reference Figure 1 , Figure 4 and Figure 5 The housing 1 has a magnet 2 at its top, and a magnet 3 at its top. The magnet 3 is fixedly connected to the bottom of the top cover 4. The bottom of the top cover 4 is fixedly connected to a positioning tenon 5, which is located on the inner wall of the housing 1. The retaining ring 12 has a limiting block 13 at its front end, and the retaining ring 14 has a limiting block 15 fixedly connected to its front end. The inner wall of the limiting block 15 is connected to the limiting block 13 via a nut 16, a screw 17, a butterfly plate 18, and a washer 19. The nut 16 is located on the inner wall of the limiting block 15. A screw 17 is threaded onto the inner wall of the pump body 6. A butterfly plate 18 is fixedly connected to the top of the screw 17. A gasket 19 is fixedly connected to the bottom of the butterfly plate 18. The gasket 19 is located at the top of the limit block 13. An oil outlet pipe 8 is fixedly connected to the top of the pump body 6. The oil outlet pipe 8 is located in the groove of the top cover 4. A rubber ring 21 is fixedly connected to the right end of the fixing ring 11. The rubber ring 21 is located at the right end of the fixing ring 22. Both the fixing ring 11 and the fixing ring 22 are made of rubber. An installation rod is fixedly connected to the top of the top cover 4.

[0028] Specifically, after cleaning and maintaining the filter plate 20, the filter plate 20 is snapped into the groove between the first fixing ring 11 and the second fixing ring 22. Then, the first fixing ring 11 and the second fixing ring 22 are engaged by the first retaining ring 12 and the second retaining ring 24. After that, the nut 16 is rotated so that the washer 19 on the screw 17 is positioned above the first limiting block 13. Then, the butterfly plate 18 is pinched and rotated. Because the screw 17 is threadedly connected to the nut 16, rotating the butterfly plate 18 will cause the screw 17 to move within the nut 16, thereby reducing the distance between the first limiting block 13 and the second limiting block 15. This process secures the retaining rings 11 and 14, completing the installation of the filter plate 20. Both retaining rings 11 and 22 are made of rubber. Due to their elasticity, the threads between the nut 16 and the screw 17 are tightened. The rubber ring 21 on the right end of retaining ring 22 acts as a seal to prevent lubricant leakage. The butterfly plate 18 is fixed to the top of the screw 17, allowing the operator to easily squeeze and rotate it, thereby driving the screw 17 to rotate and adjusting the connection status of retaining rings 12 and 14.

[0029] Working principle: The groove on the top cover 4 is fitted onto the oil outlet pipe 8. The positioning tenon 5 is aligned with the corresponding groove on the housing 1 and inserted. When the top cover 4 moves to the appropriate position, the magnetic attraction between magnet 2 and magnet 3 limits its position. After connecting the oil inlet pipe 23 and the oil outlet pipe 8 to the appropriate positions, the drive source is connected to the drive shaft 7, driving the pump body 6 to run. During operation, the noise emitted by the pump body 6 is absorbed by the sound insulation pad 9 inside the housing 1, thus reducing the noise during operation. When maintenance or replacement of the filter plate 20 is required, first pull the top cover 4 upwards to remove the positioning tenon 5 from the housing 1, exposing the pump body 6. Then, pinch the butterfly plate 18 and rotate it, driving the screw 17 to rotate, increasing the distance between the washer 19 and the nut 16. Then, rotate the nut 16 to make the screw... Once rod 17 disengages from the groove of limiting block 13, retaining ring 12 and retaining ring 24 can be removed from fixing ring 11 and fixing ring 22. Then, filter plate 20 can be disassembled from between fixing ring 11 and fixing ring 22. After cleaning and maintaining filter plate 20, fixing ring 22 is inserted into the groove between fixing ring 11 and fixing ring 22. Then, retaining ring 12 and retaining ring 24 are used to engage fixing ring 11 and fixing ring 22. Then, nut 16 is rotated so that washer 19 on screw 17 is positioned above limiting block 13. Then, butterfly plate 18 is pinched and rotated. Because screw 17 and nut 16 are threadedly connected, the distance between limiting block 13 and limiting block 25 will be reduced, fixing retaining ring 12 and retaining ring 24, thus completing the installation of filter plate 20.
