Description

Technical Field

[0001] This utility model relates to the field of speed reducer technology, and in particular to a speed reducer for an ultra-high torque heavy-duty briquetting machine. Background Technology

[0002] Ultra-large torque heavy-duty reducers are continuously operating reducers with advantages such as high torque, high transmission ratio, high transmission efficiency, and compact structure. They are high-strength, modern, large gearboxes. However, traditional reducers used in briquetting machines for customers in steel mills and other similar applications are generally large in size and weight, mostly consisting of one input shaft and two output shafts. To meet customer requirements for a relatively large distance between the two output shafts and similar rotational speeds, briquetting machine reducers typically employ at least three intermediate gear shafts to adjust the speed ratio and meet the distance requirements. This results in a large number of internal parts and a large overall footprint, which may not meet the standards of some customers' narrow workshops, limiting their application scenarios. Furthermore, their excessive weight makes them difficult to handle and move, and the cost of parts and materials is relatively high. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a high-torque heavy-duty ball press reducer that can meet the customer's requirement that the distance between the two output shafts is far and the speed ratio is close. It can also optimize the internal parts layout space, reduce the intermediate shaft, reduce the overall size and weight, and reduce costs.

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

[0005] A high-torque heavy-duty briquetting machine reducer includes a reducer housing and an input gear shaft, a first gear shaft, a second gear shaft, a first output shaft, and a second output shaft disposed within the reducer housing.

[0006] The input gear shaft, the first gear shaft, and the second gear shaft are arranged in a triangular configuration in the middle of the reducer housing. The first gear shaft meshes with the input gear shaft for transmission, and the second gear shaft meshes with the first gear shaft for transmission.

[0007] The first output shaft is located on the upper part of the reducer housing and meshes with the second gear shaft for transmission. A bridge gear is movably sleeved on the first gear shaft. The second output shaft is located on the lower part of the reducer housing and meshes with the second gear shaft through the bridge gear for transmission.

[0008] Furthermore, a deep groove ball bearing is sleeved on the first gear shaft, and the bridge gear is sleeved on the outer ring of the deep groove ball bearing.

[0009] Furthermore, a deep lubrication hole is provided at the end of the first gear shaft near the deep groove ball bearing.

[0010] Furthermore, a first gear is provided on the first gear shaft, and the toothed section of the input gear shaft meshes with the first gear;

[0011] A second gear is provided on the second gear shaft, and the toothed section of the first gear shaft meshes with the second gear.

[0012] Furthermore, a third gear is provided on the first output shaft, and the toothed section of the second gear shaft meshes with the third gear;

[0013] A fourth gear is provided on the second output shaft, which meshes with the bridge gear, and the toothed section of the second gear shaft also meshes with the bridge gear.

[0014] Furthermore, the toothed section of the input gear shaft is located at the rear, and the first gear is disposed at the rear of the first gear shaft;

[0015] The first gear shaft with toothed section is located in the middle, and the second gear is located in the middle of the second gear shaft.

[0016] Furthermore, the second gear shaft with toothed section is located at the front, and the third gear is located at the front of the first output shaft;

[0017] The fourth gear is located at the front of the second output shaft, and the bridge gear is fitted onto the front of the first gear shaft.

[0018] Furthermore, the first gear shaft, the second gear shaft, the first output shaft, and the second output shaft are located on a straight line along the diagonal of the reducer housing.

[0019] Furthermore, the front end of the input gear shaft extends out of the reducer housing, and the rear ends of the first output shaft and the second output shaft extend out of the reducer housing.

[0020] By adopting the above technical solution, this utility model has the following beneficial effects:

[0021] 1. This utility model utilizes a triangular distribution of the input gear shaft, the first gear shaft, and the second gear shaft within the reducer housing. The first and second output shafts are positioned far apart at the top and bottom of the reducer housing, respectively. A bridge gear is designed to coaxially and without interference with the first gear shaft. This allows the second gear shaft, with its toothed section, to drive the first output shaft while simultaneously driving the second output shaft via the bridge gear. This satisfies the customer's requirement for a relatively large distance between the two output shafts and a similar speed ratio. Furthermore, it optimizes the internal component layout, reduces the number of intermediate shafts, decreases the overall size and weight, and lowers costs.

[0022] 2. In this utility model, a deep groove ball bearing is added between the bridge gear and the first gear shaft for assembly. This ensures that there is no interference between the bridge gear and the first gear shaft, and that they can operate independently while sharing the space of a single shaft. This reduces space and enables lossless transmission between the toothed section of the second gear shaft and the second output shaft, which is beneficial for achieving a close speed ratio between the two output shafts.

[0023] 3. This utility model utilizes the arrangement design of the input gear shaft, first gear shaft, second gear shaft, first output shaft, and second output shaft within the reducer housing. In particular, the input gear shaft, first gear shaft, and second gear shaft are triangularly distributed, while the first gear shaft, second gear shaft, first output shaft, and second output shaft are located on a diagonal line. Combined with the staggered meshing transmission between the internal gears and gear shaft segments, this design ensures that the two output shafts are far apart and have similar speed ratios. It also allows for a compact arrangement of internal parts, optimizes the internal parts layout space, reduces internal volume, and consequently reduces the overall size and weight. This saves on housing and parts material costs, making it suitable for use in narrow workshops. It is also lighter, easier to handle and move, and meets the standard requirements of more customers, thus having a wide range of applications. Attached Figure Description

Detailed Implementation

[0028] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0029] like Figure 1-3As shown, this embodiment provides a high-torque heavy-duty briquetting machine reducer, which mainly consists of a reducer housing 1, input gear shaft 2, first gear shaft 3, second gear shaft 4, first output shaft 5, and second output shaft 6. All five shafts are housed within the reducer housing 1 and are rotatably mounted on the reducer housing 1 via self-aligning roller bearings. Taking this embodiment as an example, the user requires a rated input power of 218KW, a rated input speed of 2100 rpm, theoretical speed ratios of 14.784 and 13.83, and a distance of 1016mm between the two input shafts. Conventional designs would use one input shaft in the first stage plus two intermediate stages, with the output shaft in the last stage, requiring at least three intermediate shafts, which cannot meet the user's equipment installation and usage requirements. Furthermore, the user's dimensions do not allow for achieving two relatively close speed ratios of 14.784 and 13.83.

[0030] Therefore, refer to Figure 1-3 As shown, the structure of this embodiment is designed as follows. In this embodiment, the input gear shaft 2, the first gear shaft 3, and the second gear shaft 4 are arranged in a triangular distribution in the middle of the reducer housing 1. The first gear shaft 3 meshes with the input gear shaft 2 for transmission, and the second gear shaft 4 meshes with the first gear shaft 3 for transmission. The first output shaft 5 is located on the upper part of the reducer housing 1 and meshes with the second gear shaft 4 for transmission. A bridge gear 8 is movably sleeved on the first gear shaft 3. The second output shaft 6 is located on the lower part of the reducer housing 1 and meshes with the second gear shaft 4 through the bridge gear 8 for transmission. Thus, by the triangular distribution of the input gear shaft 2, the first gear shaft 3, and the second gear shaft 4 within the reducer housing 1, the first output shaft 5 and the second output shaft 6 are respectively positioned far apart at the upper and lower parts within the reducer housing 1. Through the design of the bridge gear 8, they are coaxially sleeved onto the first gear shaft 3 without interference. This allows the second gear shaft 4, with its toothed section, to drive the first output shaft 5 to rotate, while simultaneously driving the second output shaft 6 to rotate through the bridge gear 8. This satisfies the customer's requirement that the two output shafts be far apart yet have similar speed ratios. Furthermore, it optimizes the internal component layout space, reduces one intermediate shaft, shrinks the overall size and weight, and lowers costs.

[0031] To achieve interference-free operation between the bridge gear 8 and the first gear shaft 3, a deep groove ball bearing 7 is fitted onto the first gear shaft 3 in this embodiment, and the bridge gear 8 is fitted onto the outer ring of the deep groove ball bearing 7. This ensures that there is no interference between the bridge gear 8 and the first gear shaft 3, allowing them to operate independently. This guarantees that the two speed ratios do not affect each other, and that they share the space of a single shaft. This reduces space requirements and allows for lossless transmission between the toothed section of the second gear shaft 4 and the second output shaft 6, facilitating the achievement of a near-close speed ratio between the two output shafts. Furthermore, to extend the bearing's service life, a deep lubrication hole 9 is provided at the end of the first gear shaft 3 near the deep groove ball bearing 7 in this embodiment. Regularly adding lubricating oil ensures the reliability of the mechanism.

[0032] Specifically, to ensure the performance and normal operation of the reducer, in this embodiment, a first gear 30 is mounted on the first gear shaft 3 via a key, and the toothed section of the input gear shaft 2 meshes with the first gear 30; a second gear 40 is mounted on the second gear shaft 4 via a key, and the toothed section of the first gear shaft 3 meshes with the second gear 40. A third gear 50 is mounted on the first output shaft 5 via a key, and the toothed section of the second gear shaft 4 meshes with the third gear 50; a fourth gear 60 is mounted on the second output shaft 6 via a key, and the fourth gear 60 meshes with the bridge gear 8, and the toothed section of the second gear shaft 4 also meshes with the bridge gear 8. Thus, the input gear shaft 2 drives the first gear shaft 3 to rotate, which in turn drives the second gear shaft 4 to rotate, which in turn drives the first output shaft 5 to rotate; simultaneously, the toothed section of the second gear shaft 4 also drives the fourth gear 60 to rotate via the bridge gear 8, which in turn drives the second output shaft 6 to rotate.

[0033] More specifically, in order to further optimize the interior space, refer to Figure 1 , 2 As shown, in this embodiment, the toothed section of the input gear shaft 2 is located at the rear, that is... Figure 2 At the left end of the first gear 30, the first gear 30 is located at the rear of the first gear shaft 3; the toothed section of the first gear shaft 3 is located in the middle, and the second gear 40 is located in the middle of the second gear shaft 4. The toothed section of the second gear shaft 4 is located at the front, i.e. Figure 2 At the right end of the first output shaft 5, the third gear 50 is located at the front of the first output shaft 5; the fourth gear 60 is located at the front of the second output shaft 6; and the bridge gear 8 is fitted onto the front of the first gear shaft 3. Furthermore, in this embodiment, the first gear shaft 3, the second gear shaft 4, the first output shaft 5, and the second output shaft 6 are located on a straight line diagonally opposite the reducer housing 1; and the front end of the input gear shaft 2 extends out of the reducer housing 1, while the rear ends of the first output shaft 5 and the second output shaft 6 extend out of the reducer housing 1 for mounting other components. Of course, Figure 2 This is a cross-sectional unfolded view with multiple sections, intended only to illustrate the front-to-back position of the meshing gears and shafts. It does not represent the top-to-bottom position. Please refer to the diagram for further details. Figure 1 Refer to the overall layout and location.

[0034] refer to Figure 1-3As shown in the above design, this embodiment utilizes the arrangement of the input gear shaft 2, first gear shaft 3, second gear shaft 4, first output shaft 5, and second output shaft 6 within the reducer housing 1. In particular, the input gear shaft 2, first gear shaft 3, and second gear shaft 4 are arranged in a triangular configuration, while the first output shaft 3, second gear shaft 4, first output shaft 5, and second output shaft 6 are located on a diagonal line. Combined with the staggered meshing transmission between the internal gears and gear shaft segments, this design ensures that the two output shafts are far apart and have similar speed ratios. It also allows for a compact arrangement of internal components, optimizes the internal component layout space, reduces internal volume, and consequently reduces the overall size and weight. This saves on housing and component material costs, making it suitable for use in confined workshops. Its lighter weight facilitates handling and transfer, meeting the standard requirements of more customers and offering a wide range of applications.
