Description

Technical Field

[0001] This invention relates to the field of precision speed reducers, specifically to a pollution-resistant precision speed reducer with anti-clogging lubrication channels. Background Technology

[0002] A precision reducer is a high-precision transmission device that can reduce the speed of a power source and increase the output torque. It is widely used in fields such as robotics, aerospace, and precision machine tools where transmission accuracy and stability are extremely important. Its core feature is that it achieves micron-level or even nanometer-level transmission error control through the cooperation of precision meshing components such as gears and worm gears, ensuring high efficiency and precision in the power transmission process.

[0003] Currently, after lubricating oil is injected into a precision reducer, the lubricating oil needs to flow through pre-set narrow channels to each meshing component to achieve lubrication, cooling, and reduced wear. However, during continuous operation, impurities such as metal particles generated by gear meshing will flow with the lubricating oil in the channels, causing blockage. Consequently, the lubricating oil cannot provide sufficient lubrication, reducing the lubrication effect and affecting the service life and operating accuracy of the precision reducer. To address this issue, we propose a pollution-resistant precision reducer anti-blockage lubrication channel to solve the above problems. Summary of the Invention

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0025] According to an embodiment of the present invention, in conjunction with the appendix Figure 1-4 As shown.

[0026] A pollution-resistant precision reducer anti-clogging lubrication channel includes an oil injection pipe 1, a connecting pipe 2 fixedly connected to one side of the oil injection pipe 1, a telescopic hose 3 fixedly connected to the bottom end of the connecting pipe 2, a micro circulation pump 5 located below the telescopic hose 3, an extraction pipe 6 fixedly connected to the input end of the micro circulation pump 5, a filter cover 7 fixedly connected to the bottom end of the extraction pipe 6, a circular cover 9 inside the filter cover 7, a threaded sealing plug plate 10 fixedly connected to the bottom end of the circular cover 9, a circulation pipe 8 fixedly connected to the outer surface of the filter cover 7, and a permanent magnet filter screen 11, a metal sintered mesh 12, and a glass fiber filter screen 13 respectively inside the circular cover 9. Through the permanent magnet filter screen 11, the metal sintered mesh 12, and the glass fiber filter screen 13 inside the circular cover 9, a three-stage filtration can be formed, which can efficiently remove metal particles, large-diameter debris, and small impurities in the lubricating oil, preventing these impurities from accumulating in the small channels inside the precision reducer and reducing the risk of clogging.

[0027] In this embodiment, the inner ring at the bottom of the filter cover 7 is threaded, and the outer surface of the threaded sealing plug 10 is threadedly connected to the inner ring at the bottom of the filter cover 7. A hexagonal rotating block 15 is fixedly connected to the bottom surface of the threaded sealing plug 10. An annular sealing gasket 14 is provided inside the filter cover 7. The upper surface of the threaded sealing plug 10 is in contact with the bottom surface of the annular sealing gasket 14. The outer surface of the micro circulation pump 5 is provided with multiple fixing protrusions 17. Each fixing protrusion 17 has a fixing hole 18 on its outer surface. The threaded connection between the filter cover 7 and the threaded sealing plug 10 facilitates quick disassembly and assembly to clean internal impurities. The hexagonal rotating block 15 provides a force application point for easy operation. The annular sealing gasket 14 enhances the sealing performance of the bottom of the filter cover 7 and prevents lubricating oil leakage. Through the multiple fixing protrusions 17 and fixing holes 18, the micro circulation pump 5 can be securely installed in a suitable position on the reducer by bolts or other components to prevent it from shifting due to vibration during operation.

[0028] In this embodiment, the output end of the micro circulation pump 5 is fixedly connected to the discharge pipe 4, and the top end of the discharge pipe 4 is fixedly connected to one end of the telescopic hose 3. The outer surfaces of the permanent magnet filter screen 11, the metal sintered mesh 12, and the glass fiber filter screen 13 are all threadedly connected to the inner ring of the circular cover 9. The outer surface of the circular cover 9 is provided with annularly arranged through holes 16, and the through holes 16 are located below the permanent magnet filter screen 11. The bottom end of the oil injection pipe 1 is fixedly connected to the injection flange 20, and one end of the circulation pipe 8 is fixedly connected to the oil outlet flange 21. The inner ring of the top end of the oil injection pipe 1 is threaded. A sealing plug 22 is connected to the outer surface of the connecting pipe 2, and a one-way valve 19 is fixedly connected to it. The permanent magnet filter screen 11, the metal sintered mesh 12, and the glass fiber filter screen 13 are threadedly connected to the inner ring of the circular cover 9, which facilitates the individual replacement of damaged filter screens. The through hole 16 allows lubricating oil to smoothly enter the filter screen for filtration. The injection flange 20 and the oil outlet flange 21 facilitate the connection of the oil injection pipe 1, the circulation pipe 8 and the corresponding interface of the reducer. The sealing plug 22 at the top of the oil injection pipe 1 seals the pipe opening when no oil is being injected to prevent impurities from entering. The one-way valve 19 can prevent the backflow of lubricating oil in the connecting pipe 2 and ensure the stability of the circulation direction.

[0029] Working principle: When lubricating oil is injected into the reducer through the oil injection pipe 1, the micro circulation pump 5 starts and draws the lubricating oil containing impurities into the filter cover 7 through the extraction pipe 6. At this time, the lubricating oil first flows through the permanent magnet filter screen 11 in the circular cover 9, and uses magnetism to attract the metal particles generated by gear meshing. Then, it passes through the metal sintered mesh 12 to intercept larger particles of debris, and finally passes through the glass fiber filter screen 13 to filter out small impurities. The purified lubricating oil flows back to the main channel through the telescopic hose 3 and the connecting pipe 2 in sequence, ensuring the cleanliness of the lubricating oil entering the precision reducer and avoiding blockage of small channels.

[0030] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
