[0001] This utility model relates to the field of speed reducer support technology, and in particular to a speed reducer support structure for sedimentation tanks. Background Technology

[0002] In fields such as the production of phosphate inorganic salts and wastewater treatment, thickeners are indispensable equipment. Their function is to separate solid particles in slurry or wastewater by gravity. As a key transmission component of the thickener, the performance and lifespan of the reducer directly affect the operating efficiency and reliability of the thickener. However, the traditional reducer support structure has many problems, which limits the further improvement of the thickener's service life.

[0003] During operation, traditional gearbox support seats are prone to bearing damage from vibration and impact loads, which may cause the main shaft to deform excessively due to unstable support, affecting rotational accuracy. In addition, there is also the problem of lubricant leakage inside the bearing. When external impurities can easily enter the bearing, they will accelerate the wear of internal bearing components, thereby reducing the service life of the equipment and increasing maintenance costs. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of many problems existing in the traditional reducer support structure, which reduces the service life of the equipment, and to propose a reducer support structure for sedimentation tanks.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A sedimentation tank reducer support structure includes a reducer base and a main shaft used in conjunction with the reducer base. The reducer base is equipped with a transmission component capable of driving the main shaft to rotate. The transmission assembly includes a base flange and a support flange fixedly mounted on the reducer base. The outer wall of the main shaft is provided with a lower coupling and an upper coupling.

[0015] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figure 1 - Figure 5 As shown, the present invention provides a sedimentation tank reducer support structure, including a reducer base 10 and a main shaft 11 used in conjunction with the reducer base 10. The reducer base 10 is equipped with a transmission assembly 20 that can drive the main shaft 11 to rotate. The transmission assembly 20 ensures the normal operation of the thickener and extends its service life. The transmission assembly 20 includes a base flange 21 and a support flange 22 fixedly mounted on the reducer base 10. The reducer base 10 can be installed through the base flange 21 and the support flange 22. The base flange 21 is usually used to connect the reducer base 10 to the foundation (such as the ground, ground or foundation steel frame, etc.). With fasteners such as bolts, the base flange 21 can firmly fix the entire reducer base 10 assembly to the foundation, preventing the equipment from shifting or tilting due to vibration or other reasons during operation, and ensuring the stability and safety of the equipment. The support flange 22 is used to connect the reducer base 10 assembly to the external support structure (such as bracket, frame, etc.). It can tightly combine the reducer base 10 assembly with the support structure to form a stable overall structure, enhance the overall rigidity and stability of the equipment, prevent unnecessary movement or shaking during operation, and ensure the normal operation and service life of the equipment.

[0017] The outer wall of the main shaft 11 is provided with a lower coupling 23 and an upper coupling 24. The upper coupling 24 is installed at the top of the main shaft 11 and is connected to the output shaft of the reducer. It transmits the torque from the output shaft of the reducer to the main shaft 11, ensuring that the main shaft 11 can obtain sufficient torque to rotate, thereby driving the rake frame and other components of the thickener to mix and process materials. It can play a certain role in overload protection. If the main shaft 11 or the components of the thickener are jammed or overloaded, the upper coupling 24 can protect the reducer and the main shaft 11 from damage by sliding or slipping. The lower coupling 23 is installed at the bottom of the main shaft 11 and connected to the output shaft of the motor. It transmits the torque from the motor output shaft to the main shaft 11, enabling the main shaft 11 to obtain driving torque to rotate, thereby driving the thickener's rake frame and other components to mix and process materials. This arrangement ensures the stability and reliability of the entire transmission system, reduces equipment vibration and wear, and improves the service life of the equipment. The outer wall of the spindle 11 is also equipped with a bearing 25. The bearing 25 provides support for the rotating spindle 11, bearing the weight of the spindle 11 and its components, as well as various loads (such as torque and bending moment) generated during equipment operation. This allows the spindle 11 to rotate stably and maintain its position and orientation. Without the support of the bearing 25, the spindle 11 may bend, vibrate, or even break during rotation, causing the equipment to malfunction. The stable support of the bearing 25 ensures the rotational accuracy of the spindle 11 and the normal operation of the equipment. The reducer base 10 is also equipped with a protective component 26 that can protect the bearing 25, and an auxiliary component 27 that is used in conjunction with the protective component 26.

[0018] like Figure 3 - Figure 5 As shown, the protective component 26 includes a bearing housing 261 fixedly installed inside the reducer base 10, a cover plate 262 placed on the top of the bearing housing 261, and a gasket 263 provided inside the bearing housing 261.

[0019] In more detail, the bearing 25 is installed inside the bearing housing 261, which provides stable support for the bearing 25, ensuring that the bearing 25 can maintain the correct position and posture during operation. The shim 263 is located between the bearing 25 and the bearing housing 261, and the shim 263 is made of rubber. The shim 263 can be used to adjust the relative position between the bearing 25 and the bearing housing 261, ensuring the concentricity and alignment of the bearing 25 with other related components. Good concentricity and alignment can reduce vibration and stress concentration during equipment operation, and extend the service life of the bearing 25 and related components.

[0020] In more detail, a pressure cap 264 is installed at the bottom of the bearing housing 261 and the top of the cover plate 262, respectively. The bearing 25 is axially fixed by the pressure cap 264 and the cover plate 262. Through the tight fit with the bearing housing 261, the pressure cap 264 and the cover plate 262 limit the bearing 25 in the axial direction to prevent the bearing 25 from moving axially due to the action of axial force during operation. An oil seal 265 is provided in the middle of the pressure cap 264. Its main function is to prevent lubricant (such as lubricating oil or grease) from leaking out from the gap between the bearing 25 and the shaft, and also to prevent external contaminants from entering the interior of the bearing 25.

[0021] In more detail, the inner ring of the oil seal 265 contacts the surface of the main shaft 11. The oil seal 265 is made of nitrile rubber, which has good elasticity and wear resistance. It can fit tightly against the surfaces of the main shaft 11 and the bearing 25 to form an effective sealing barrier. Rubber vibration isolation pads are also provided on the bearing housing 261 and the cover plate 262. The rubber vibration isolation pads are located at the upper and lower ends of the bearing 25. The rubber vibration isolation pads can effectively isolate the vibration generated by the bearing 25 during operation and prevent these vibrations from being transmitted to other parts of the equipment or the foundation structure. Through its elastic deformation, it absorbs and dissipates vibration energy, thereby reducing the vibration level of the entire equipment, improving the stability and reliability of the equipment operation, thereby extending the service life of these components and reducing the maintenance cost and downtime of the equipment.

[0022] In more detail, the auxiliary component 27 includes a locking block 271 fixedly installed at the bottom of the cover plate 262. Grooves 272 are respectively formed on both sides of the locking block 271, and a slot 273 is formed at the top of the bearing seat 261. Sealing rings 274 are symmetrically installed in the slots 273. After the bearing 25 is installed onto the bearing seat 261, the cover plate 262 is placed on the bearing seat 261. At this time, the locking block 271 at the bottom of the cover plate 262 will insert into the slot 273. When the locking block 271 is fully inserted, the sealing rings 274 will also engage in the grooves 272. Figure 5 As shown, the sealing between the bearing housing 261 and the cover plate 262 effectively prevents external impurities (such as dust, moisture, oil, etc.) from entering the bearing 25, while also preventing lubricant leakage. Maintaining the cleanliness and good lubrication of the bearing 25 is one of the key factors in extending the service life of the bearing 25.

[0023] In more detail, the size of the locking block 271 is adapted to the locking groove 273, the size of the groove 272 is adapted to the sealing ring 274, and the bearing housing 261 and the cover plate 262 are respectively connected to the reducer base 10 by screws with reinforcing members. The reinforcing members can improve the connection between the bearing housing 261 and the cover plate 262 and the reducer base 10, and can effectively improve the rigidity and deformation resistance of the bearing housing 261.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
