Description

Technical Field

[0001] This utility model relates to the technical field of speed reducers, specifically to a thin and light gear reducer. Background Technology

[0002] A speed reducer is a power transmission mechanism that uses the speed conversion function of transmission elements such as gears and worm gears to reduce the rotational speed of a motor or other prime mover to the required value while increasing the output torque. The lightweight gear reducer is a gear transmission device that achieves lightweight and compactness through structural innovation. Its core design lies in the integrated housing and bearing sharing mechanism, which significantly reduces the size and weight while maintaining high transmission efficiency, high precision and stability.

[0003] In the operation of a slim gear reducer, the internal lubricating oil plays a crucial role, ensuring efficient, stable, and long-term operation. However, with prolonged use, mechanical wear occurs between gears and bearings due to constant friction between components, generating impurities. These impurities often mix with the lubricating oil. If not treated promptly, they migrate with the lubricating oil between components, accelerating wear on gears and bearings and reducing the reducer's lifespan. Therefore, those skilled in the art have provided a slim gear reducer to address the problems mentioned in the background section. Utility Model Content

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A lightweight gear reducer includes a base, a cover at the top of the base, a drive shaft inside the base, a gear set between the base and the cover, and a collection assembly inside the base for collecting impurities in the lubricating oil. The collection assembly includes a magnet plate inside the base, a frame on the magnet plate, a push plate fixedly mounted on the frame, and a rotating plate fixedly mounted on the drive shaft for cooperating with the push plate to move the magnet plate.

[0006] Preferably, a limiting block is fixedly installed in the base, and a locking block is fixedly installed on the frame, with the locking block slidably connected in the limiting block.

[0007] Preferably, a spring is fixedly connected between the card block and the base, and the spring is located in the limiting block, and the magnet plate is slidably connected in the frame.

[0008] Preferably, the push plate has an arc surface, and the end of the rotating plate is arranged in an arc shape to match the arc surface.

[0009] Preferably, the magnet plate has several through holes for lubricating oil to pass through, thereby enhancing the fluidity of the lubricating oil in the base.

[0010] Preferably, the base is provided with a sealing part, a sealing plate is fixedly connected to the sealing part, and a sealing gasket is provided on the sealing plate.

[0011] Preferably, the magnet plate is provided with a screw, and the screw is threadedly connected to the frame through the magnet plate.

[0012] The beneficial effects of this utility model are:

[0013] This invention, by incorporating a collection component, enables the magnetic plate in the base of the speed reducer to adsorb and collect metal debris particles from the lubricating oil during use. This prevents metal debris impurities from further accelerating wear as they move between the gear sets with the lubricating oil, thus affecting the lifespan of the speed reducer. Simultaneously, the rotation of the drive shaft drives the rotating plate to rotate, and the combined action of the rotating plate and the push plate allows the magnetic plate to move up and down cyclically. This dynamic magnetic field enhances adsorption efficiency, expands the effective range, and reduces adsorption blind spots, significantly improving the adsorption effect. Consequently, the magnetic plate achieves higher adsorption efficiency and better results for metal debris in the lubricating oil. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to embodiments:

[0022] This utility model discloses a thin and light gear reducer. (Refer to...) Figures 1-6 The reducer includes a base 1, a cover 2 at the top of the base 1, a drive shaft 3 inside the base 1, and a gear set between the base 1 and the cover 2. The gear set and drive shaft 3 are existing technologies and work together in the base 1 and the cover 2, which will not be described in detail here. The base 1 is equipped with a collection component for collecting impurities in the lubricating oil in the base 1. By setting up the collection component, the metal debris and impurities generated by friction inside the reducer can be collected during long-term use, thereby preventing the metal debris and impurities from further accelerating wear and affecting the service life of the reducer as they float between the gear sets with the lubricating oil. The collection component includes a magnet plate 4 in the base 1, a frame 5 on the magnet plate 4, a push plate 6 fixedly installed on the frame 5, and a rotating plate 7 fixedly installed on the drive shaft 3 to cooperate with the push plate 6 to move the magnet plate 4.

[0023] Reference Figures 1-6 Specifically, a limiting block 8 is fixedly installed in the base 1, and a locking block 9 is fixedly installed on the frame 5. The locking block 9 is slidably connected in the limiting block 8. A spring 10 is fixedly connected between the locking block 9 and the base 1, and the spring 10 is located in the limiting block 8. The magnet plate 4 is slidably connected in the frame 5. The push plate 6 has an arc surface 11. The end of the rotating plate 7 is arc-shaped to match the arc surface 11. When the reducer is working, the transmission shaft 3 rotates as the gear set rotates. A lubricating oil pool is provided at the bottom of the inner cavity of the base 1. When the gear set rotates, the lubricating oil adheres to the gears, thereby lubricating the gears. As the gear set rotates and passes through the lubricating oil, the lubricating oil becomes fluid, allowing metal debris to flow in it. At this time, the magnet plate 4 can adsorb and collect the metal debris, preventing it from floating between the base 1 or the gear set with the flowing lubricating oil, thus preventing the metal debris from affecting the parts.

[0024] As the drive shaft 3 rotates, it drives the rotating plate 7 to rotate. When the rotating plate 7 rotates and contacts the push plate 6, the end of the rotating plate 7 is arc-shaped, matching the arc surface 11 on the push plate 6. Under the pressure of the rotating plate 7, the push plate 6 is pushed downward, which in turn pushes the bottom frame 5 downward. This causes the locking block 9 on the frame 5 to move downward within the limiting block 8. The spring 10 contracts under pressure, generating a reaction force. As the rotating plate 7 continues to rotate and disengages from the push plate 6, the pressure on the push plate 6 is released. Under the reaction force of the spring 10, the locking block 9 moves upward within the limiting block 8 to reset, thus resetting the frame 5. Therefore, during the continuous cyclical rotation of the rotating plate 7, the frame 5 can be repositioned. The magnet plate 4 moves up and down continuously, which enhances the adsorption efficiency, expands the effective range, and reduces the adsorption blind zone through the dynamic magnetic field, thereby significantly improving the adsorption effect. This makes the magnet plate 4 more efficient and effective at adsorbing metal debris in the lubricating oil. The magnet plate 4 has several through holes 12 for the lubricating oil to pass through, which enhances the fluidity of the lubricating oil in the base 1. The through holes 12 allow the lubricating oil to pass through the magnet plate 4 when it moves up and down, preventing the magnet plate 4 from blocking the lubricating oil. This increases the fluidity of the lubricating oil, which accelerates the diffusion and migration of metal debris in the lubricating oil, allowing it to enter the magnetic field range of the magnet plate 4 more quickly, thus accelerating the adsorption efficiency.

[0025] Reference Figures 1-6 Specifically, the base 1 is provided with a sealing part 13, and a sealing plate 14 is fixedly connected to the sealing part 13. A sealing gasket 15 is provided on the sealing plate 14. A screw 16 is provided on the magnet plate 4, and the screw 16 is threaded through the magnet plate 4 and connected to the frame 5. When the metal particles adsorbed on the surface of the magnet plate 4 reach saturation, the magnet plate 4 can be separated from the frame 5 by opening the sealing plate 14 and rotating the screw 16. Then the magnet plate 4 can be taken out through the inlet and outlet of the sealing part 13, the metal particles on the surface of the magnet plate 4 can be cleaned, and then it can be put back into the frame 5. The sealing gasket 15 on the sealing plate 14 is replaced, and then the sealing plate 14 is fixed back to the sealing part 13. This process is carried out when the reducer is maintained. When the reducer is maintained, the lubricating oil is replaced, and after draining the lubricating oil, the magnet plate 4 is cleaned.

[0026] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
