Description

Technical Field

[0001] This utility model relates to the field of speed reducer technology, specifically a speed reducer that facilitates lubrication oil replacement. Background Technology

[0002] A speed reducer is an independent component consisting of gear transmission, worm transmission, or gear-worm transmission enclosed in a rigid housing. It is commonly used as a speed reduction transmission device between the prime mover and the working machine. It plays a role in matching speed and transmitting torque between the prime mover and the working machine or actuator. It is a widely used transmission device in modern machinery. For speed reducers, changing the lubricating oil is an important part of maintenance.

[0003] According to the application number CN202021620807.2, a speed reducer that facilitates lubrication oil replacement solves the problem of how to avoid the inconvenience of lubrication oil replacement in traditional speed reducers.

[0004] However, the following problems still exist in actual use:

[0005] (1) When using it, it is necessary to open the seal with the help of an external object and then put the lubricating oil into the inside of the reducer. Therefore, it is more complicated to inject the lubricating oil, which will increase the operating burden and is not conducive to its promotion and use in reality.

[0006] (2) During installation and use, it is only installed and used through the base plate and connecting holes. It cannot be installed and used according to different placement environments. This will reduce the stability in actual use and also reduce the corresponding range of installation and use.

[0007] Therefore, this utility model introduces a speed reducer that facilitates lubrication oil replacement. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides a speed reducer that facilitates lubricant replacement, offering advantages such as easier lubricant replacement and greater stability during installation and use, thus solving the problems mentioned in the background art.

[0009] This utility model provides the following technical solution: a speed reducer that facilitates lubrication oil replacement, comprising a base plate, a moving mechanism provided on the upper surface of the base plate, the moving mechanism comprising a main body, a cover plate, a rotating rod, a gear, a toothed plate and a baffle, the bottom of the main body being fixedly installed with the upper surface of the base plate, the cover plate being snapped into the interior of the main body on all four sides, the outer surface of the rotating rod being rotatably connected to the interior of the cover plate, the interior of the gear being fixedly installed with the outer surface of the rotating rod, the front of the toothed plate meshing with the outer surface of the gear, and the left side of the baffle being fixedly installed with the right side of the toothed plate.

[0010] Preferably, the base plate has mounting mechanisms on both the front and rear sides of its upper surface. Each mounting mechanism includes a fixed rod, a rotating block, and a limiting groove. The outer surface of the fixed rod is fixedly installed to the interior of the base plate, the interior of the rotating block is rotatably connected to the outer surface of the fixed rod, and a limiting groove is formed inside the rotating block.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This type of reducer, which facilitates lubricant replacement, utilizes a through groove and an oil inlet. These features allow for easy lubricant replacement by opening the groove and inlet. The rotating rod, gears, gear plate, and baffle allow for the movement of the baffle, opening or closing the through groove and inlet without external assistance. The movable groove ensures stable sliding of the baffle, facilitating smooth operation and solving the problem of simplifying lubricant replacement. This reduces the number of steps involved in lubricant replacement, simplifying operation, reducing the workload, and promoting its widespread adoption.

[0018] 2. This type of reducer, which facilitates lubrication oil replacement, utilizes a fixed rod, a rotating block, and a limiting groove. The position of the limiting groove on the upper surface of the base plate can be changed to adapt to different installation needs. The mounting holes are used to ensure that different mounting hole positions coincide with the limiting groove, resulting in a more stable overall installation. This solves the problem of installation stability, allowing for installation based on specific requirements and improving practical stability. Attached Figure Description

The outer surface of the rotating rod 9 is rotatably connected to the interior of the cover plate 5. The interior of the gear 10 is fixedly installed to the outer surface of the rotating rod 9. The front of the gear plate 11 meshes with the outer surface of the gear 10. The left side of the baffle 12 is fixedly installed to the right side of the gear plate 11. The bottom of the gear 10 is in contact with the upper surface of the cover plate 5. The bottom of the toothed plate 11 is in contact with the upper surface of the cover plate 5. The cover plate 5 has a movable groove 13 inside. The inner wall of the movable groove 13 is slidably connected to the outer surface of the bottom end of the baffle 12, and the bottom of the movable groove 13 is in contact with the upper surface of the cover plate 5. The main body 2 has an oil filling port 8 inside, and the cover plate 5 has a through groove 7 inside. By using the main body 2, cover plate 5, rotating rod 9, gear 10, toothed plate 11, baffle 12, movable groove 13, through groove 7 and oil filling port 8, the steps when changing lubricating oil can be reduced, which improves the ease of operation in reality, helps to reduce the operational burden, and will also help to promote its use in practice.

[0026] Please see Figure 4 The base plate 1 has mounting mechanisms 19 on both the front and rear sides of its upper surface. Each mounting mechanism 19 includes a fixed rod 14, a rotating block 15, and a limiting groove 16. The outer surface of the fixed rod 14 is fixedly installed to the interior of the base plate 1.

By using the fixed rod 14, the rotating block 15, the limiting grooves 16, and the mounting holes 17, the installation effect can be achieved according to the actual situation, and it can adapt to different installation requirements, thus improving the stability of actual use.

[0027] Please see Figure 1 and Figure 2 An oil plug 4 is inserted inside the right side of the main body 2. A limit screw 6 is connected to the internal thread of the cover plate 5, and the outer surface of the limit screw 6 is connected to the internal thread of the main body 2.

[0028] Working principle: During installation, the entire assembly is first moved to the installation location. Then, depending on the installation location, the rotating block 15 can slide on the outer surface of the fixing rod 14 inside the base plate 1, allowing the rotating block 15 to rotate. Then, depending on the installation environment, the rotating block 15 is rotated to the corresponding position, so that the position of the limiting groove 16 inside the rotating block 15 coincides with the mounting holes 17 at different positions. Finally, the mounting rod is installed inside the limiting groove 16 and the mounting holes 17 to ensure the position of the base plate 1 and the main body 2 on the upper surface of the base plate 1, ensuring stability during use.

[0029] When changing the lubricating oil, first open the oil plug 4 to drain the old lubricating oil, and then reinsert the oil plug 4 into the main body 2. When injecting new lubricating oil, first rotate the rotating rod 9. When rotating the rotating rod 9, the gear 10 fixedly mounted on the outer surface of the rotating rod 9 can rotate synchronously. When the gear 10 rotates, the position of the toothed plate 11 meshing with the gear 10 can be changed on the upper surface of the cover plate 5. Move the position of the toothed plate 11 to the left so that the position of the baffle 12 fixedly mounted on the right side of the toothed plate 11 can slide to the left along the inner wall of the moving groove 13, exposing the positions of the through groove 7 and the oil inlet 8. Then, align the lubricating oil with the oil inlet 8 and inject the lubricating oil into the interior of the main body 2. After injecting the lubricating oil, move the position of the baffle 12 to the right, and then block the positions of the through groove 7 and the oil inlet 8 again.
