Description

Technical Field

[0001] This utility model mainly relates to the field of speed reducers, and specifically to a base for mounting speed reducers. Background Technology

[0002] In modern industrial production, speed reducers, as a key transmission device, are widely used in various heavy machinery fields such as mining, metallurgy, chemical industry, and hoisting and transportation. Their core function is to reduce speed and increase torque through gear meshing, thereby meeting the power requirements of different equipment.

[0003] To ensure stable and reliable operation of the speed reducer, a sturdy base is typically required. This base is fixed to the foundation using anchor bolts or other fasteners. Simultaneously, the speed reducer body is rigidly connected to the base via mounting holes on its bottom, forming a so-called "hard connection." This connection method is simple in structure, has good rigidity, and can effectively withstand the vibrations and torques generated during speed reducer operation. It is currently the most common and traditional installation method.

[0004] However, the inventors of this application have discovered through long-term practice and application that this traditional hard-connection method has a long-overlooked but far-reaching technical defect: During continuous operation of the speed reducer, the multi-stage gears inside inevitably generate metal shavings and tiny impurities such as sludge formed by aging lubricating oil during high-speed or heavy-load meshing transmission. These impurities mix with the circulating lubricating oil. Because the speed reducer housing and base are tightly fitted with rigid connecting surfaces, there are no gaps between them for maintenance or inspection. After the equipment has been running for a period of time, the lubricating oil mixed with impurities can easily leak slowly from the speed reducer output shaft seal, housing mating surfaces, and other extremely small gaps.

[0005] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0020] See attached document Figure 1-3A base for mounting a speed reducer includes a base structure 1, a speed reducer body 2 is provided on the top of the base structure 1, and fixing strips 3 are rotatably connected to the four corners of the speed reducer body 2, the fixing strips 3 being threadedly connected to the base structure 1. The base structure 1 includes a base body 101, a sealing ring 105 on the top of the base body 101, a material discharge bin 106 inside the base body 101, a filter feeding structure inside the material discharge bin 106, the top of the filter feeding structure being located inside the reducer body 2, side support bars 102 on both sides of the base body 101, fixing bolt holes 103 inside the side support bars 102, and positioning bolt holes 104 on the top of the base body 101. The positioning bolt holes 104 are threadedly connected to the fixing bars 3. The reducer body 2 is installed on the top of the base body 101, with the sealing ring 105 aligned with the groove at the bottom of the reducer body 2. Then, the fixing bars 3 are inserted into the reducer body 2, with one end of the fixing bars 3 contacting the positioning bolt holes 104, thereby fixing the fixing bars 3. Finally, lubricating oil is poured into the reducer body 2 for lubrication during operation.

[0021] The filter feeding structure includes a filter baffle 107 and a servo motor 112. The filter baffle 107 is disposed on the inner wall of the discharge bin 106, and the two sides of the filter baffle 107 are inclined. An opening is provided on one side of the discharge bin 106, and a plug is provided inside the opening. A connecting pipe 108 is disposed in the middle of the filter baffle 107. Guide pipes 109 are provided on both sides of the top of the connecting pipe 108. A horizontal pipe 110 is provided at the top of the guide pipe 109, and a liquid outlet 111 is provided on the inner side of the horizontal pipe 110. The servo motor 112 is disposed at the bottom of the discharge bin 106, and a feeding screw 113 is provided at the output end of the servo motor 112. The feeding screw 113 is rotatably connected to the connecting pipe 108. The inner wall of the connecting pipe 108 and the discharge bin 106 is provided with a liquid inlet 114. The outer wall of the liquid inlet 114 is provided with a liquid inlet 115. After passing through the gears inside the reducer body 2, the lubricating oil enters the discharge bin 106. The discharge bin 106 filters the impurities inside the lubricating oil. At the same time, the filtered lubricating oil enters the bottom of the discharge bin 106. The servo motor 112 is started, and the servo motor 112 drives the feeding screw 113 to rotate. The lubricating oil enters the connecting pipe 108 through the liquid inlet 115. Then, the lubricating oil enters the guide pipe 109 through the connecting pipe 108 and enters the horizontal pipe 110 and is discharged through the liquid outlet 111, so that the lubricating oil comes into contact with the gears inside the reducer body 2 again. At the same time, the plug is opened, and impurities on the surface of the filter baffle 107 can be cleaned through the opening that is flush with the top of the filter baffle 107.

[0022] Installation and sealing: Place the reducer body 2 on top of the base structure 1, ensuring that the groove at the bottom of the reducer body 2 is aligned with the sealing ring 105 at the top of the base body 101 to form a sealed connection and prevent lubricating oil leakage.

[0023] The reducer body 2 is fixed to the base structure by threading the fixing strip 3 into the positioning bolt holes 104 on the top of the base body 101. The fixing strip 3 is rotatably connected to the four corners of the reducer body 2, providing stable rigid support.

[0024] Lubricating oil circulation and filtration: Lubricating oil is injected into the reducer body 2 for lubrication during gear meshing. During operation, after the lubricating oil comes into contact with the gears, it flows into the discharge bin 106 inside the base structure through the bottom of the reducer body 2 due to gravity or circulating pressure.

[0025] After the lubricating oil enters the discharge bin 106, it first comes into contact with the filter baffle 107. The filter baffle 107 has an inclined design on both sides, which facilitates the accumulation of impurities in the central area, while allowing the lubricating oil to flow downward through gaps or holes. Impurities are trapped at the top of the filter baffle 107.

[0026] The filtered clean lubricating oil accumulates at the bottom of the discharge hopper 106.

[0027] Lubricating oil return and circulation: The servo motor 112 is started, and its output drives the feeding screw 113 to rotate inside the connecting pipe 108. The rotation of the feeding screw 113 generates a pumping action, drawing the lubricating oil at the bottom of the discharge bin 106 into the inlet bin 114 through the inlet port 115 and into the connecting pipe 108.

[0028] The lubricating oil then enters the horizontal pipe 110 through the guide pipe 109 at the top of the connecting pipe 108, and is finally discharged from the outlet 111 inside the horizontal pipe 110, and is sprayed again or returned to the gears inside the reducer body 2 to complete the circulation and filtration of the lubricating oil.

[0029] Impurity removal: During regular maintenance, open the plug on the side of the hopper 106 and filter through the top of the opening filter baffle 107. Because the filter baffle 107 is inclined on both sides, impurities tend to accumulate near the opening. The trapped impurities can be cleaned manually or with tools to ensure filtration efficiency.

[0030] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
