Description

Technical Field

[0001] The utility model belongs to the technical field of mixers, and in particular relates to a reducer box structure for a planetary mixer. Background Art

[0002] Vertical planetary mixers are a key piece of equipment widely used in fields like construction and road construction. One of their core components is the reducer housing. The design of the reducer housing directly impacts the driving force output for the mixer's rotation and revolution, as well as the equipment's stable operation.

[0003] Traditional reducer housings require the drive shaft bearings to be installed and positioned via bearing cap bosses. These bosses are typically bolted to the housing's inner wall to ensure bearing stability. However, this design presents the following issues:

[0004] 1. High manufacturing cost: The bearing cover boss needs to be processed and purchased independently, and high-precision processing and matching are required when assembling it with the housing, which increases the overall manufacturing cost and process complexity.

[0005] 2. Lubricant contamination: The reducer housing is filled with lubricating oil to lubricate the gears and bearings. However, gaps can easily form between the bearing cover boss and the housing. After prolonged operation, oil deposited on the housing wall can enter these gaps and be unable to drain with the lubricant. When the lubricant is replaced, any residual oil can contaminate the newly added lubricant, affecting lubrication effectiveness and reducing the equipment's service life.

[0006] 3. Difficulty in Maintenance: During long-term operation, gear meshing can generate iron filings, and foreign matter can also enter the reducer housing. These impurities easily accumulate on the housing surface or enter the bearing holes, making them difficult to clean thoroughly. This not only shortens the lubricant's operating cycle but also accelerates bearing wear, reducing bearing life and the overall stability of the reducer.

[0007] 4. Decreased equipment stability: Due to the existence of the above problems, the reducer is prone to poor lubrication and bearing failure during long-term operation, resulting in a decrease in the smoothness and reliability of equipment operation. Utility Model Content

[0047] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0048] like Figure 1 As shown, in an exemplary embodiment of the planetary mixer reducer housing structure of the present invention, the planetary mixer reducer housing structure includes a housing 1, an input shaft 2, an output shaft 3 and a gear transmission assembly 4;

[0049] The mixer comprises a main body and a mixing drum mounted thereon. A housing 1 is rotatably mounted on the main body and positioned above the mixing drum. An input shaft 2 and an output shaft 3 are both mounted on the housing 1. The input shaft 2, extending upward from the housing 1, is connected to a drive motor mounted thereon. The drive motor is connected to the input shaft 2 via a mechanical transmission mechanism such as a belt drive or gear drive. The output shaft 3, extending downward from the housing 1, is connected to a stirring mechanism, which extends downward into the mixing drum.

[0050] The gear transmission assembly 4 is mounted within the housing 1 and includes a plurality of gear transmission members 41 arranged sequentially from the input shaft 2 to the output shaft 3. The gear transmission member 41 includes a transmission shaft 42 and a transmission gear 43 mounted on the transmission shaft 42. The input gear 21 mounted on the input shaft 2 meshes with the transmission gear 43 of the adjacent gear transmission member 41, and the transmission gears 43 of adjacent gear transmission members 41 mesh with each other. The output gear 31 mounted on the output shaft 3 meshes with the transmission gear 43 of the adjacent gear transmission member 41, thereby providing a transmission connection between the input shaft 2 and the output shaft 3 through the gear transmission assembly 4.

[0051] When the driving motor drives the input shaft 2 to rotate, the input shaft 2 drives the output shaft 3 to rotate through the gear transmission members 41 of the gear transmission assembly 4, thereby driving the stirring device to rotate in the stirring barrel to stir the material in the stirring barrel.

[0052] The gear transmission assembly 4 also includes a revolving gear 44, located outside the housing 1 and fixedly mounted on the transmission shaft 42 of one of the gear transmission members 41. This revolving gear 44 meshes with an internal gear ring 5 fixedly mounted on the housing, which is coaxial with the housing 1. When the gear transmission assembly 4 drives the output shaft 3, it simultaneously rotates the revolving gear 44, which, through its engagement with the internal gear ring 5, drives the housing 1 to rotate. This causes the stirring mechanism on the output shaft 3 to revolve, stirring the material at various locations within the mixing drum.

[0053] To ensure smooth rotation of the shaft components, bearings 6 are installed on the input shaft 2, the output shaft 3, and the transmission shafts 42 of each gear transmission member 41. A boss 11 is integrally formed on the inner surface of the bottom plate of the housing 1. The bearings 6 installed at the lower ends of the output shaft 3, the input shaft 2, and each transmission shaft 42 are all located in corresponding bearing holes 12 provided on the boss 11. The bearings 6 installed at the upper ends of the output shaft 3 and each transmission shaft 42 are all located in corresponding bearing holes 12 provided on the top plate of the housing 1. The upper and lower bearings 6 are fixed by the upper and lower bearing holes 12 to achieve the installation of each shaft component in the housing 1. In order to ensure the long-term normal operation of the input shaft 2, the output shaft 3, and each gear transmission member 41 in the housing 1, the housing 1 is filled with lubricating oil to reduce the wear caused by the rotation of the shafts and the meshing of the gears.

[0054] After the reducer has been used for a long time, the lubricating oil filled in the housing 1 will produce oil stains, and the friction between the components during operation in the housing 1 will also produce impurities such as iron filings. The impurities and oil stains will settle to the lowest point in the internal space of the housing 1. Since the bearing hole 12 for mounting the bearing 6 is set on the boss 11,

[0055] After the reducer has been used for a long time, the lubricating oil filled in the box body 1 will produce oil stains, and the oil stains will settle to the lowest point in the internal space of the box body 1.

[0056] In the above-mentioned schematic embodiment, the planetary mixer reducer housing structure is provided with a boss 11 on the bottom plate of the housing 1, and the bearing hole 12 is provided on the boss 11. The boss 11 is used to provide an installation position for the bearing 6. The boss 11 and the bottom plate are integrally formed, and the manufacturing cost is low. There is no gap between the two, so that the connection between the two will not cause oil and dirt to remain. Since the top surface of the protrusion is higher than the top surface of the bottom plate, more or even all impurities and oil and dirt are deposited on the bottom plate, avoiding impurities and oil and dirt from falling into the bearing hole 12 and being retained therein, ensuring that impurities and oil and dirt can be more fully discharged with the lubricating oil when the reducer is maintained, thereby improving the convenience and maintenance effect of equipment maintenance, avoiding the contamination of newly added lubricating oil due to retained oil and dirt, improving equipment stability and service life, and solving the problems of high manufacturing cost, lubricating oil pollution, maintenance difficulty and reduced equipment stability of the current reducer housing 1.

[0057] In order to further prevent the formation of oil and impurities on the boss 11, the edges of the boss 11 are all chamfered, so that the oil and impurities falling on the boss 11 can slide smoothly onto the bottom plate.

[0058] In some embodiments, as Figures 1 to 3 As shown, a accommodating bin 7 is mounted on the bottom plate of the box body 1 , an oil communication port 13 communicating with the accommodating bin 7 is disposed on the bottom plate of the box body 1 , and a plug 71 is mounted on the oil discharge port of the accommodating bin 7 .

[0059] During the operation of the reducer, impurities such as iron slag and oil stains that settle on the bottom plate of the housing 1 will fall directly downward into the oil connection port 13 and then into the storage chamber 7, leaving the interior of the housing 1. This prevents them from adhering to the bottom plate surface due to long-term accumulation in the housing 1, thus ensuring the cleanliness of the interior of the housing 1. By removing the plug 71 and opening the oil drain port, the internal lubricating oil can be discharged so that new lubricating oil can be filled in to facilitate maintenance of the reducer.

[0060] In some embodiments, a filter screen 72 is installed in the storage bin 7, and the filter screen 72 covers the oil drain port, so that after impurities such as iron slag and oil stains are precipitated and fall into the storage bin 7, they fall on the filter screen 72. The filter screen 72 has mesh holes and low adhesion ability, thereby preventing impurities from adhering to the inner wall of the storage bin 7 and causing difficulty in cleaning.

[0061] In some embodiments, the storage compartment 7 includes a protective shield 73 and an end cap 74. The protective shield 73 surrounds the lower surface of the bottom plate of the housing 1 to form a storage space with a port on the lower side. The end cap 74 is mounted on the protective shield 73 and seals the port of the storage space. The oil drain port is provided on the end cap 74, and the filter 72 is mounted on the end cap 74.

[0062] After opening the oil drain port to drain the lubricating oil, the end cover 74 can be removed to open the accommodating chamber 7, so that the inside of the accommodating chamber 7 can be cleaned; the filter screen 72 is located on the removed end cover 74, which is convenient for further removing the filter screen 72 from the end cover 74. The filter screen 72 can be cleaned or replaced separately, thereby improving the cleanliness of the accommodating chamber 7 after cleaning, so that after the box body 1 is filled with new lubricating oil, it can once again accommodate impurities such as oil, iron filings, etc. generated during the operation of the reducer.

[0063] In some embodiments, as Figures 4 and 5As shown, end cap 74 is provided with a downwardly protruding oil collecting groove 75, with the oil drain port located at the bottom surface of oil collecting groove 75. The sidewalls of oil collecting groove 75 are inclined, and filter screen 72 is mounted on the top port of oil collecting groove 75. The downwardly recessed oil collecting groove 75 provides further space for impurities such as iron filings and oil to sink. Filter screen 72 is installed at the end of oil collecting groove 75, which can maximize the interception and retention of iron filings with a small structural area, achieving low cost and high efficiency. The gradually narrowing structure of oil collecting groove 75 from top to bottom allows more accumulated oil to be concentrated towards the drain port. Therefore, after the drain port is opened, the oil can be discharged as quickly as possible, ensuring the effectiveness of reducer oil change maintenance.

[0064] In some embodiments, the inner surface of the bottom plate of the box body 1 is inclined downward from the outside to the oil connecting port 13, so that when the oil stains fall onto the bottom plate, they will fall along the inclined surface into the oil connecting port 13, ensuring that impurities such as iron filings and oil stains are discharged from the box body 1.

[0065] Since the input shaft 2, the output shaft 3 and each transmission shaft 42 are all shaft components in the housing 1, and the shaft components are distributed over a large range in the housing 1, if only one boss 11 is provided for the installation of the bearing hole 12, the upper surface area of ​​the boss 11 will be too large, and oil stains will still be easily retained thereon. In addition, the large-area boss 11 will also occupy the layout space of the oil connecting port 13, so that it can only be arranged at the corners of the bottom plate. The oil stains deposited at the edge of the other end of the bottom plate away from the oil connecting port 13 will find it difficult to fall into the oil connecting port 13, resulting in poor sedimentation and discharge effect of impurities such as oil stains.

[0066] To this end, in some embodiments, the outside of the oil communication port 13 is provided with a plurality of bosses 11, that is, a plurality of bosses 11 are provided, thereby ensuring that the upper surface area of ​​each boss 11 is small, preventing oil from being deposited on the surface of the bosses 11. The bosses 11 are all located outside the oil communication port 13, that is, the oil communication port 13 is located in the center of the plurality of bosses 11, so that it is in the center of the bottom plate. Impurities such as oil deposited on the bottom plate will be concentrated from the outside to the inside toward the oil communication port 13. Impurities such as oil that fall on the bosses 11 will also fall into the oil communication port 13 nearby, thereby discharging impurities in the housing 1 into the storage chamber 7 to the greatest extent possible, thereby improving the cleanliness of the housing 1, ensuring the lubricating effect of the lubricating oil on the shaft components, and improving the stability of the reducer operation.

[0067] In some embodiments, the transmission gear 43 on the gear transmission member 41 includes a primary gear 43A and a secondary gear 43B. The input gear 21 mounted on the input shaft 2 meshes with the primary gear 43A of the adjacent gear transmission member 41. The output gear 31 mounted on the output shaft 3 meshes with the secondary gear 43B of the adjacent gear transmission member 41. The secondary gear 43B of a gear transmission member 41 meshes with the primary gear 43A of another adjacent gear transmission member 41. The outer diameter of the primary gear 43A is larger than that of the secondary gear 43B. The primary gears 43A of adjacent gear transmission members 41 are arranged axially stacked.

[0068] Gear transmission element 41 is connected to two adjacent shaft components via different transmission gears 43. The gear ratio between primary gear 43A and secondary gear 43B increases the speed of output shaft 3, achieving the speed reduction or acceleration function of the reducer. Furthermore, the primary gears 43A are axially layered, i.e., the primary gears 43A are arranged alternately from inside to outside. This not only improves the transmission ratio but also allows for a more compact arrangement of adjacent gear transmission elements 41, reducing the space occupied by gear transmission assembly 4 and the volume of housing 1.

[0069] In some embodiments, the box body 1 includes an upper shell 14 and a lower shell 15, the lower shell 15 is a bottom plate, the lower side of the upper shell 14 is open, the lower shell 15 is installed on the upper shell 14 and closes it, the output mounting seat 16 is integrally arranged on the lower shell 15, and the output shaft 3 is passed through and installed on the output mounting seat 16.

[0070] Traditional vertical-shaft planetary mixer reducer housings consist of an upper housing, a lower housing, an output shaft mounting base, and a bearing end cap. The output shaft mounting base is installed below the lower housing, increasing the housing interface, the risk of oil leakage, and manufacturing costs. To address this issue, the output mounting base 16 is integrated into the lower housing 15. The housing 1 is assembled solely from the upper and lower housings 14, 15, reducing the assembly interface and reducing the risk of oil leakage in the reducer.

[0071] In addition, the bottom plate of the box body 1 is used as the lower shell 15. After it is removed from the upper shell 14, the upper surface of the lower shell 15 is the top surface of the bottom plate, which is the place where oil and dirt are most likely to accumulate. The lower shell 15 has a smaller structure and is easy to remove for cleaning.

[0072] In some embodiments, a retaining ring 8 is mounted in a mounting groove formed around the inner wall of the bearing hole 12, and the retaining ring 8 is attached to the corresponding bearing. For two bearings 6 mounted at both ends of the same shaft component, the upper and lower retaining rings 8 respectively limit the axial position of the corresponding bearing 6 from the upper and lower directions, ensuring a stable installation of the bearing 6 in the bearing hole 12 and preventing the bearing 6 from falling onto the bottom surface of the bearing hole 12 and making large-area contact with it. A space for accommodating lubricating oil is formed between the bearing 6 and the bottom surface of the bearing hole 12, allowing the oil to more fully contact the bearing 6 axially, thereby improving lubrication.

[0073] The retaining rings 8 can be installed on both the upper and lower sides of the same bearing 6. The retaining rings 8 on the inner side are respectively mounted on the transmission shaft, input shaft and output shaft. They can serve as a closed structure to prevent large particles of impurities such as iron filings from falling into the bearing hole 12 and contacting the bearing 6 when it is reversed, causing wear. The gap between the retaining ring 8 and the shaft component ensures the infiltration of lubricating oil, ensuring that the lubricating oil effectively lubricates the bearing 6. The retaining ring 8 is installed in the installation groove for stable installation.

[0074] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0075] The above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention. They should all be included in the scope of the technical solution for which protection is requested in the present invention.
